Description

TECHNICAL AREA

The technical field relates to devices and methods for disinfecting fixed lines, for example supply lines filled with water, which lead to an operating theater. Methods for disinfecting the device are also affected. Disinfection can take place, for example, in preparation for medical operations in the hospital, in which sterility is particularly important, especially immediately after an operation.

BACKGROUND

Fixed pipelines or hoses are used in hospitals for medical technology media or fluids, which have to meet high purity requirements. For example, in hypothermia applications, especially in connection with surgical interventions (e.g. on the heart), there is a tendency to no longer set up hypothermia devices directly next to the patient in an operating room, but rather in an anteroom that is separated from it. This lowers the risk of introducing germs into the operating room using the hypothermia devices. This is particularly important in cardiology.

However, supply and discharge lines for medical technology medium or fluid from the vestibule to the operating room and back are then required. In hypothermia applications, these are supply lines filled with the heat carrier water, which provide a heat or cold supply for e.g. a heat exchanger of a heart-lung machine. At least four fixed lines are common, in particular two feed lines and two return lines, e.g. for a heart-lung machine and an operating table. Up to now it has not been possible to check in a simple manner whether or to what extent these lines are germ-free. This uncertainty is currently becoming less and less acceptable, especially with regard to bacteria, the influence of which on the human organism is not sufficiently well known up to now. There is often a requirement to at least comply with the Drinking Water Ordinance.

One of the reasons for the increased demands on the purity of such lines is the risk of introducing mycobacteria into the operating room or even introducing them to the patient. Mycobacterial infection is often difficult to diagnose. It is even feared that symptoms caused by mycobacteria will only show up after many months or years. This situation makes a diagnosis more difficult and increases the uncertainty regarding the origin of the bacteria. This means that even higher requirements must be placed on the purity of inlet and outlet lines.

In this context, mycobacteria or a biofilm that is deposited on the inner walls of medical technology lines are particularly worth mentioning. The biofilm is also problematic in that many fixed lines continuously carry water or are filled with water. The water remains in these pipes for a long time. A biofilm should therefore be removed with as little residue as possible. In particular, mycobacteria should also be killed as completely as possible.

Various methods and devices are known for disinfecting medical instruments in containers or chambers provided for this purpose, be it by applying liquid disinfectants or steam.

The patent specification DE 3838046 C2 describes a process for the thermal disinfection of a water supply system and sets itself the task of enabling disinfection without changes to the structure of the system. A water heater can provide water at an elevated temperature, which can be fed into the supply system.

The pamphlet DE 600 20 268 T2 describes a process in which special plastic lines in dialysis clinics are rinsed with disinfected hot water. The hot water should also be usable for the dialysis machines. The pamphlet US 2002/0102182 A1 describes a device by means of which water can be heated before it is made available in order to sterilize it. The pamphlet WO 02/11773 A1 describes a device for continuously providing sterile water. The pamphlet WO 2014/082855 A1 describes the provision of sterile water, especially for dialysis machines.

However, it has not yet been satisfactorily clarified which devices or which processes could be used to disinfect relatively voluminous fixed lines, preferably in such a way that disinfection can be carried out quickly or without special prior knowledge or without special infrastructure even after day-to-day operations in hospitals, for example. In cardiac clinics, this would be possible during a period of usually six to eight hours at night. A verifiability of the disinfection processes is also desired, in particular for the purpose of tracing the sources of germs.

The task is to provide a device or a method with which the disinfection of fixed lines can be done in a simple manner, in particular without the risk of infections from the environment, or without technical effort, or without complex preparatory and reworking, or even without special prior knowledge of a person Operator of the device. It is also the task to design a device in such a way that it can be traced or reconstructed in which way disinfection took place. Last but not least, it is the task of designing a device in such a way that the relevant components thereof can be kept sterile, even if the device is also arranged at least temporarily in non-sterile areas.

SUMMARY

The object is achieved by a disinfection device according to claim 1 or its use and by a method according to the independent method claim. Advantageous further developments are explained in the respective subclaims. The features of the exemplary embodiments described below can be combined with one another, unless this is explicitly denied.

Insbesondere kann das Reservoir kann derart dimensioniert sein, dass die Desinfektionsvorrichtung spülmediumautonom ist.

The object is achieved by a disinfection device for the thermal disinfection of inner surfaces of fixed lines, in particular medical lines, with:

• a reservoir for rinsing medium, in particular additive-free water, for disinfecting a respective fixed line;
• at least one feed line going out from the reservoir with an outlet for coupling the disinfection device to a respective fixed line to be disinfected;
• a heating device for providing the flushing medium with a setpoint temperature, which is higher than room temperature, of at least 73 ° C. for the stationary lines, in particular in the reservoir, at the outlet and / or at the inlet;
• a control device coupled to the heating device for setting, controlling and / or regulating a temperature of the flushing medium;
• at least one measuring device coupled to the control device for detecting at least one measured variable of the flushing medium including a temperature;
• a return line for returning flushing medium from the stationary line back into the disinfection device with an inlet for coupling the respective stationary line to be disinfected to the disinfection device or to the return line; wherein the disinfection device is rinsing medium autonomous without external rinsing medium supply and is designed as a mobile standing device. In particular, the reservoir can be dimensioned in such a way that the disinfection device is independent of the flushing medium.

The disinfection device is set up to disinfect inner surfaces or elongated, narrow, comparatively voluminous cavities with a large length-to-width ratio. Several stationary lines can be coupled together in series and form a longer line, e.g. four medical technology lines, each of which is connected to one another in pairs with a connecting hose. This arrangement requires three connecting hoses, which can be made of silicone, for example.

In contrast to the disinfection or sterilization of e.g. endoscopes or other medical-technical instruments in sterilization chambers, the disinfection device is set up to disinfect cavities outside or external to the disinfection device, i.e. cavities not integrated into the disinfection device and also not surrounded by the disinfection device. For this purpose, the disinfection device provides flushing medium with a specific volume flow, in particular also in a continuous manner. A continuously sustained, for example constant, flushing medium volume flow can enable good monitoring or control of the disinfection process.

The disinfection device can be set up to carry out the disinfection without supplying rinsing medium exclusively by means of a supply of energy, in particular by means of energy supplied via a power line. The disinfection device can optionally also have an energy store and also be energy self-sufficient, at least with regard to one or more disinfection processes. This is because disinfection or self-disinfection can then take place completely independently of any supply lines or energy flows, that is to say at any location.

The autonomy of the disinfection device enables numerous fixed lines in a hospital to be disinfected one after the other in a short time, e.g. the lines to two operating theaters every night. Time-efficient disinfection can provide advantages, especially in large heart centers with ten or more operating theaters, for example.

It has been shown that the control of bacteria can be made much easier, when disinfection processes are standardized and documented. The disinfection device is set up for thermal disinfection based on a fully automatic disinfection process with documentation of the disinfection location (cannot be manipulated), the disinfection temperature, the disinfection time, the amount of rinsing medium circulated, with fully automatic sampling being possible as an option. The disinfection device is set up to carry out the disinfection process completely without operating personnel. After the disinfection device has been used and transported to a service point, the fully automatic emptying, cleaning and disinfection of the disinfection device can take place there (self-disinfection). This disinfection process can also be fully documented.

The reservoir can be dimensioned in such a way that the disinfection device does not require any external supply of rinsing medium, but remains independent of the rinsing medium, even if a comparatively voluminous line is to be disinfected. The reservoir can be made of stainless steel, for example. Stainless steel is advantageous in terms of sterility. The reservoir can, for example, be temperature-resistant up to 110 ° C, 150 ° C, 200 ° C or well above 200 ° C. The reservoir can be made comparatively voluminous and, for example, have a volume in the range of 120 or 150 liters. The reservoir can be for receiving or holding a volume corresponding to a multiple of the volume of the respective stationary line, for example 3, 4 or 5 times (factor 3 to 5). This enables a comparatively large energy buffer to be provided. Last but not least, this also enables the desired minimum temperature (in particular 73 ° C) to be maintained, especially when the flushing medium is circulated. A reservoir with a multiple of the volume of the fixed line also provides great security. In particular, it can be ruled out that the flushing medium introduced and circulated reduces the energy content of the flushing medium in the reservoir to such an extent that the temperature falls below the minimum temperature. An amount of energy can be provided which is at least a difference greater than the amount of energy that is given off or lost to the environment when flowing through the stationary line. It can be ruled out that the disinfection process has to be repeated at a higher temperature.

The disinfection device can also provide a return tank for receiving used flushing medium. Used flushing medium can first be fed into the reservoir (circulation) and / or at least partially directly into the return tank. The return can lead to the return tank and / or reservoir.

The return tank can also be made comparatively voluminous and, for example, have a volume in the range of 125 or 150L. The return tank can be dimensioned in such a way that the disinfection device is independent of the flushing medium and also does not require a connection for discharging used flushing medium.

The return tank is preferably arranged separately or separately from the reservoir. This enables a separation of unused flushing medium and used flushing medium. Unused, aseptic flushing medium can optionally be made available at any point in the process. Optionally, part of the flushing medium held ready in the reservoir can be circulated, for example in a second step, after a line with a particularly high bacterial load is disinfected in a first step by introducing flushing medium directly into the return tank. Optionally, all of the flushing medium held ready in the reservoir can be circulated.

The reservoir is advantageously arranged above or above the return tank. This enables the reservoir to be emptied into the return tank without introducing energy, in particular through gravitational forces. A drain or drainage pipe can be provided at the bottom of the return tank. The entire disinfection device can then be emptied without the input of energy.

The return tank or a fitting connected to it can be temperature-resistant up to well over 100 ° C or up to over 200 ° C. A temperature resistance in the range of 150 ° C or 200 ° C also enables these components to be disinfected using a flushing medium in the gas phase.

The outlet can for example be provided on the feed line or a hose connected to it. A standardized plug-in coupling that closes tightly on both sides can be provided at the inlet or outlet. A temperature sensor can, for example, be arranged on the feed line and / or on the return line.

The control device can have a computing unit (CPU). The control device can have a control device. The control device can be coupled to a data or program memory or have this. Program data and / or measured values or predetermined target values can be stored in the memory. For example, program data for multiple wash programs are automatic to perform Rinsing or automatic disinfection stored. Optionally, program data for at least one processing program for the automatic processing of the disinfection device are also stored. Calendar or time data or time programs for autonomously establishing the operational readiness of the disinfection device, in particular for autonomous self-disinfection, can also be stored.

A stationary, in particular medical-technical line is to be understood as a pipe, a hose or any other pre-installed, stationary supply line for disinfected or sterile media or fluids required, for example, in connection with operations, especially in hospitals. The fixed line can also be referred to as a house line or a hospital line. An example of such lines are inlet and outlet lines for hypothermia devices, which are installed in a room in front of an operating room or operating room, e.g. in a washroom. However, the supply and discharge lines must meet strict purity requirements. The stationary line can be designed as a heat transfer line for hypothermic devices, with corresponding fluid-tight couplings. The fixed line can have an (internal) volume of e.g. 5L to 10L. Several lines coupled to one another can also have a volume of e.g. 15L or 20L. Another example of such a fixed pipe is a water pipe, which must comply with the Drinking Water Ordinance.

At one (respective) open end, the stationary line can have a coupling, in particular a stainless steel coupling, which closes tightly on both sides. This enables coupling without leaking water. Two open ends of a respective stationary line can be coupled to the outlet and the inlet. Two lines lying next to each other can be connected, for example, with a silicone hose, in particular with a hose arranged in an operating room. This can be done by a cardio technician, for example.

The flushing medium can then flow completely through the line. This also makes it possible to control the disinfection process by means of adjustable flow rates, pressure or dwell times and to optimize its effectiveness or efficiency. For example, water of at least drinking water quality can be used as the rinsing medium.

A measuring device is to be understood as a device for acquiring one or more measured variables or measured values. The measuring device can have one or more sensors each for one or more measured variables. The sensors can be provided at different positions or components of the disinfection device.

A feed line is to be understood as a line for supplying or forwarding flushing medium. The feed line comprises at least those line sections which lead from the reservoir to the outlet.

“Autonomous rinsing medium” is to be understood as a device which does not require a rinsing medium or disinfectant supply in order to be able to carry out the disinfection process. During one or more disinfection processes, the rinsing medium can be provided solely by the disinfection device. The disinfection device is then, at least temporarily, self-sufficient with regard to the flushing medium. The disinfection device is self-sufficient, for example also with regard to a comparatively large volume of a large number of stationary lines. For this purpose, the volume of the reservoir can be a multiple of the volume of the line (s) to be disinfected. The reservoir has, for example, a volume in the range of 100L or 150L or even up to 250L. By means of a disinfection device that is independent of the flushing medium, for example, all stationary lines of a hospital ward can be disinfected without the need for a flushing medium supply. Last but not least, this enables a hospital infrastructure to be made leaner.

Since several stationary lines can be disinfected by means of a single filling of the reservoir, a large part of the otherwise necessary cleaning work in the area of the line connections in the respective vestibule or operating room can be dispensed with.

A device that is independent of a flushing medium supply also provides the advantage that sterility of the flushing medium can be more easily monitored or logged. The disinfection device is also self-sufficient in that it can be provided in a disinfected, sterile state. In particular, the disinfection device is set up for self-disinfection. This reduces the risk of germs or bacteria entering fixed lines during disinfection. Couplings or connections can also be brought to a minimum temperature during disinfection. This can be ensured, for example, that the disinfection device has temperature sensors at both the outlet and the inlet.

The disinfection device can be designed as a displaceable, mobile standing device, in particular for absorbing weight forces well over 100kg or 200kg. The disinfection device can be mobile, in particular rollable or Have rollers or wheels for moving. At least one of the wheels can be lockable or coupled to a braking device. Each wheel can, for example, be designed for a static load of 300-500kg, but at least 100kg. The wheels can be designed according to the permissible floor load, in particular to avoid excessive pressure peaks. The wheels can be electrically dissipative.

The disinfection device can have a motor drive for controlled displacement. For example, individual roles can be driven. The disinfection device can have a considerable overall weight. If the reservoir, cold tank and return tank are all completely filled, the total weight can be e.g. 250-300kg, or in the range of up to 500kg. One or more motorized drives, which can optionally also be controlled via an input mask or e.g. a joystick, can facilitate or accelerate the displacement of the disinfection device. Automatic brakes can also be provided and / or a respective drive can also be set up to exert a braking force.

The disinfection device can have a display and input unit, by means of which an input mask is provided for displaying, for example, measured values and for entering, for example, target values. For example, a user can specify a desired disinfection temperature, e.g. a minimum value of 73 ° C and / or a minimum disinfection time, in particular at the specified disinfection temperature.

Further developments and exemplary embodiments are described below.

According to one embodiment, the disinfection device is set up to form a disinfectable, hermetic or sealable circuit which is also externally arranged with respect to the disinfection device by means of the feed line and the return in connection with a respective stationary line. In other words: the disinfection device can be set up to disinfect lines arranged externally from or outside the disinfection device, in particular also to document temperature, pressure and / or flow values with respect to an external section of the circuit. The circulation can also enable circulation. The entire circulation can be temperature-resistant up to e.g. 110 ° C or 150 ° C or 200 ° C. Circulation has the advantage that a large flow rate can also be achieved with a comparatively small volume. An energy buffer can also be provided. By creating a circuit, it is possible, for example, by recording measured values at the inlet, to determine which temperature and which flow rate or pressure a particular line section was exposed to. It can be useful to record the measured values at least at the inlet and at the outlet. In particular, the measured values recorded at the inlet can be used to assess and document the type of disinfection.

The disinfection device can be set up to provide a target temperature at the outlet and / or at the inlet. This enables the disinfection to be carried out outside the disinfection device, that is to say not in a chamber within the disinfection device, but in external sections of the circuit. Maintaining a target temperature at the inlet, ie in the area of the return, can ensure that external sections of the circulation, ie the fixed line, were exposed to a certain minimum temperature. The time is also preferably recorded.

According to one embodiment, the disinfection device is set up for the automatic rinsing and disinfection of a respective fixed line by a circuit or in a circuit (circuit management) by the heating device and / or a conveying device of the disinfection device from the control device depending on the feed line and the return recorded measured values, one or more operating variables can be specified, in particular power output, delivery rate, and / or operating interval. The control device for setting, controlling and / or regulating at least one measured variable can be in communication with at least one sensor of the measuring device.

According to one exemplary embodiment, the disinfection device has a conveying device designed to convey flushing medium through the feed line and a respective stationary line. The conveying device can be set up to convey fluid, that is to say both liquid and gas.

The delivery device can be connected to the flushing medium reservoir and the cold container via one or more lines. The delivery device can have at least one pump, in particular for providing the flushing medium with a predetermined pressure at the outlet.

The conveying device can be set up to build up a pressure in the range of, for example, 3 bar. The conveying device can be designed to flush stationary lines with a length in the range of, for example, 200 m. The conveying device can be set up to flush stationary lines that are located extend in the vertical direction over a height of, for example, 15 m or more. This makes it possible, for example, to flush lines from one floor which extend into other floors.

The disinfection device can e.g. be designed for the nominal pressure PN16 and approved for a working pressure of 10 bar. It is then possible to flush pipes with a height difference of up to approx. 100 m.

The delivery device can have a compressor for providing compressed air, in particular sterile, medical-technical compressed air from the supply network of a hospital.

The disinfection device can have a compressed air connection and compressed air lines connected to it, in particular for pressures in the range of 5 bara.

According to one embodiment, the reservoir is a hot reservoir for providing and holding flushing medium with a temperature of at least 73 ° C, in particular at least 102 ° C. The hot reservoir is set up to provide flushing medium with a temperature in the range from 73 ° C. to over 100 ° C., each of the temperature values in between can be provided or maintained. A temperature above 100 ° C can be used to provide flushing medium in the gas phase. The hot reservoir can hold ready a flushing medium volume corresponding to a multiple of the volume of the line (s) to be disinfected, in particular with a temperature above 73 ° C. Since a certain volume of flushing medium, in particular hot water, can be kept available, in particular at least in drinking water quality, a flushing medium-autonomous device can also be provided for comparatively long or voluminous fixed lines, in particular without chemical additives.

The reservoir can be designed to hold a comparatively large volume of flushing medium in the liquid phase. The reservoir can be supported on a frame or base of the disinfection device in order to transfer weight forces well over 100 kg.

A hot reservoir is to be understood as a container in which hot rinsing medium can be kept and / or heated to a desired temperature suitable for disinfection.

By means of a hot reservoir, it is also possible to flush a large volume of flushing medium with a high energy or heat content through the respective stationary line in a short time.

The heating device can be set up to increase a flushing medium volume of 60L or 100L or 150L or up to 250L with the heat capacity of water to a temperature of at least 70 ° C, in particular at least 80 ° C, optionally also to just below 100 ° C heat. In this way, the self-sufficiency or autonomy can be further improved.

The heating device can also be arranged at least partially on and / or in the reservoir. The heating device can, for example, have at least one heating rod or heating coil. The heating device can also be arranged at least partially on and / or in the feed line.

The heating device advantageously has at least two heating elements which extend in the reservoir. Each heating element can have its own power connection, in particular for 230V and / or 400V. Thus, depending on the power supply on site, heating energy can be entered with one or both or more heating elements. Last but not least, this can save time.

The heating device can be set up to heat up a volume of e.g. 20L to 60L water in a few minutes. A respective heating element can have a power consumption of e.g. 3KW to 12KW.

The reservoir can have thermal insulation, in particular for the purpose of efficient storage of thermal energy introduced into the flushing medium. For example, the insulation can be disposed outside of the reservoir.

The disinfection device can be set up to heat all components carrying rinsing medium to a minimum temperature, in particular at least 73.degree. C., preferably at least 80.degree. The limit of 80 ° C provides a good compromise between thermal load on the fittings and efficient and reliable heating of all components to at least 73 ° C. The minimum temperature of approx. 80 ° C is also useful for purely thermal self-disinfection.

The heating to the minimum temperature can take place either by means of a flushing medium or even without a flushing medium based solely on thermal conduction or thermal radiation. The heating device can be dimensioned and arranged in such a way that all components carrying the flushing medium can be heated to a minimum temperature, in particular at least 73.degree. As a result, sterility can be ensured with a high degree of security. The components are preferably heated to above 73.degree in the case of self-disinfection by means of a flushing medium in the gas phase, in particular water vapor.

According to one embodiment, the disinfection device is set up to disinfect exclusively by thermal disinfection, in particular against (myco) bacteria, germs and contamination at temperatures of at least 73 ° C., in particular also by means of a flushing medium in the gas phase. It has been shown that a temperature above 72 ° C can destroy, if not all, most of the bacteria, especially if the temperature is longer than 10 minutes. is held. The disinfection device can be set up to ensure a degree of disinfection in accordance with A0 600.

It has been shown that disinfection by means of (water) steam or air inclusions or flushing medium in the gas phase is more effective or can be carried out more efficiently. In particular, air inclusions can cause turbulence and, for example, attack a biofilm more efficiently than flushing medium that is exclusively present in the liquid phase.

According to one embodiment, the disinfection device is set up for purely thermal self-disinfection, and in particular also for self-diagnosis. Purely thermal self-disinfection is to be understood as a disinfection of the disinfection device by itself, in particular also independent of the flushing media. The purely thermal self-disinfection can in particular be carried out using a flushing medium in the gas phase. A self-diagnosis is to be understood as a control or regulating loop by means of which the disinfection device can check its own degree of disinfection (self-test). The self-diagnosis can include blocking the disinfection device or at least blocking connections or a disinfection process.

According to a variant, a sample of the used rinsing medium can be provided after self-disinfection, in particular fully automatically by filling a sampling container, e.g. with a volume of 0.5L. This enables an optional control by an independent testing laboratory. Such laboratories are often located in clinics, so that a certain degree of disinfection or sterility can also be certified in a simple manner from an external location for the disinfection device. The sampling container can, for example, be connected directly to the reservoir and / or a cold container or return container or a further component or line. The disinfection device can also comprise several sampling containers, in particular for fully automatic sampling both when disinfecting stationary lines and when disinfecting itself. This enables the sampling containers to be sent together to the laboratory, e.g. after several fixed lines have been disinfected or several self-disinfections have taken place.

According to one embodiment, the disinfection device further comprises a cold container, in particular a cold water container, connected to the reservoir, the cold container being connected to the reservoir by means of a supply bypass, in particular a pipe open on both sides, which supply bypass has two free ends which enter the cold container and protrude into the reservoir, in particular up to a predefined fill level. In particular, this arrangement also facilitates self-disinfection.

The cold container can provide flushing medium with a significantly cooler temperature compared to the reservoir, e.g. at room temperature. The cold container can be made comparatively voluminous and e.g. have a volume in the range of 40 or 50 liters. The cold container can be arranged at the same height as the reservoir, in particular with respect to the container bottom. This can enable an advantageous, compact arrangement of all containers and facilitate the emptying of the containers.

The stationary line can be rinsed by means of the cold container before and / or after a disinfecting step, in particular for the purpose of cooling the line. Lines or components of the disinfection device can also be washed around and cooled.

The cold container can be connected to the reservoir by means of one or more switchable lines as well as by means of a line that is constantly open (supply bypass). An open bypass can ensure self-disinfection without complex circuit technology, in particular by means of a flushing medium in the gas phase.

The cold tank can optionally also be connected to a / the return tank. The return tank can have a volume corresponding to at least the sum of the volumes of the reservoir and the cold tank. This means that the entire contents of the reservoir and cold container can be taken up by the return tank. This improves the self-sufficiency or autonomy of the disinfection device.

The cold container is advantageously arranged next to the reservoir and / or above the return container. With this arrangement, both the reservoir and the cold container can only enter the reservoir via a natural gradient without pumping work The return water tank must be emptied. The return tank is advantageously arranged under the reservoir and / or under the cold container. Last but not least, this minimizes a required conveying capacity.

The cold container is advantageously connected to the reservoir and the return container, in particular via valveless pipes that are open on both sides. Last but not least, this also enables effective or efficient device processing, in particular by means of (water) steam or flushing medium in the gas phase. A pipe connection between the reservoir and the cold container can be designed in such a way that no gas exchange can take place between these containers during normal disinfection operation when flushing fixed lines. A pipe connection between the cold container and the return water container can be designed in such a way that it can also function as an overflow of flushing medium to the return container.

The disinfection device can have a trolley on which the reservoir and the two containers are arranged and can be moved together.

The reservoir and the respective container can each have a drain. The reservoir and the respective container can each have valves on inlet and outlet lines as well as at least one temperature sensor and at least one level sensor.

As described above, the feed bypass can have two free ends. In the cold container, the free end can stand in the rinsing medium in the liquid phase, in particular in drinking water, in particular at least during the disinfection of a fixed line. In other words: In the cold container, the free end can be arranged at a height that is below the level in the cold container, and optionally also lower than the free end in the reservoir. This enables a hydrostatic barrier between the reservoir and the cold container, in particular during the disinfection process on the stationary line. In particular, it can thereby be avoided that the flushing medium passes into the cold container in the gas phase.

The supply bypass can connect the reservoir with the cold container in series, in particular for the purpose of common disinfection by means of a flushing medium in the gas phase. Flushing medium in the gas phase can be passed through these components and associated fittings, in particular without the need to build up excess pressure. Rather, a small pressure difference in the range of a few millibars, e.g. 10mbar, can be sufficient.

When disinfecting the fixed line, the feed bypass enables a safety mechanism. The feed bypass is arranged and shaped in such a way that liquid flushing medium cannot escape from the reservoir via the feed bypass. However, a pressure transition can take place, for example in the event that a phase change takes place and a gaseous flushing medium is formed. This means that reliable, low-risk operation can also take place at comparatively high temperatures (in particular at over 90 ° C or even 95 ° C, if desired). The supply bypass can prevent overpressure from building up in the reservoir. The supply bypass can remain open on both sides. The supply bypass can extend higher than a maximum fill level in the reservoir. This can ensure that liquid rinsing medium cannot get from the reservoir into the cold container, but only gaseous rinsing medium.

The supply bypass can also serve to pass on flushing medium, in particular flushing medium in the gas phase for processing or disinfecting the disinfection device. It has been shown that disinfection can be carried out in a particularly reliable and efficient manner by means of the supply bypass, in particular without the need to guide flushing medium by means of nozzles into certain corners or nooks and crannies of the components of the disinfection device that carry the flushing agent.

According to one exemplary embodiment, the supply bypass is designed to be open on both sides and without valves without valves. It has been shown that this comparatively simple structure provides many device-related and process-related advantages. Valves and control technology can be saved. In this way, it can also be completely excluded that a pressure builds up in the reservoir when the flushing medium in the reservoir is heated. The reservoir and cold container do not necessarily have to be designed, tested or approved as pressure vessels. Steam or flushing medium in the gas phase can escape through the supply bypass or the pipe. A valveless, open supply bypass provides a robust arrangement which can be operated by means of a simple control.

According to one exemplary embodiment, the supply bypass extends in a U-shape with ends that are open at the bottom on both sides. This enables flushing medium to be introduced in the gas phase in such a way that the flushing medium flows around or through the cold container from bottom to top. This can also prevent condensate from collecting in the feed bypass.

According to one embodiment, a free end of the supply bypass that extends vertically in the cold container overlaps in the vertical direction a free end of the discharge bypass that extends vertically in the reservoir. This can ensure that the flushing medium flows through the cold container as completely as possible. At the same time, the cold container and reservoir can be arranged at least approximately at the same height. The overlapping arrangement provides advantages with regard to a complete flow through the cold container and with regard to the arrangement of the containers relative to one another.

According to one embodiment, the free end of the supply bypass extends deeper or further down in the cold container than the free end of the supply bypass in the reservoir. This makes it easier to set a hydrostatic lock. Since the open end of the supply bypass in the cold container is arranged comparatively close to the floor, a small amount of flushing medium in the cold container can be sufficient to prevent an exchange between the reservoir and the cold container. The higher the level in the cold container, the greater the counter pressure.

According to one embodiment, the disinfection device has a return container, the cold container being connected to the return container by means of a discharge bypass, in particular a pipe open on both sides, which discharge bypass has two free ends which protrude into the cold container and into the return container, in particular each up to a predefined fill level. The discharge bypass enables an unobstructed gas exchange between the cold tank and the return tank. The discharge bypass can connect both containers in series, especially behind the reservoir. When disinfecting the fixed line, the discharge bypass also enables an overflow from the cold tank into the return tank.

According to one embodiment, the disinfection device has a return container and a cold container as well as a supply bypass and a discharge bypass, which bypasses form an open series connection of the reservoir with the two containers. This enables the reservoir and both containers to be disinfected in a simple manner, in particular by feeding flushing medium in the gas phase through the open series connection. The disinfection can also be carried out particularly efficiently, in particular in terms of time. Despite the voluminous container, the arrangement can be heated to over 80 ° C in just a few minutes.

The first end of the discharge bypass can be arranged above the supply bypass, in particular in an upper third of the cold container. The supply bypass and the discharge bypass can overlap in the cold container over the greatest possible length. This can ensure a comparatively long flow path for flushing medium in the gas phase.

According to one embodiment, the disinfection device is set up to automatically disinfect itself (self-disinfection) by flushing the reservoir with one or more further containers in an open series connection using flushing medium in the gas phase, in particular without valve switching in the series connection. The flushing medium can, for example, condense at the end of the series connection, in particular in the return tank, and then be discharged. Automatic switching of valves in the system can also ensure that all containers, pipes and fittings of the disinfection device are disinfected.

According to the invention, the disinfection device is designed as a mobile, displaceable standing device. As described above, a displaceable disinfection device facilitates handling and expands the possible uses and increases the autonomy. Shifting can at least be supported by the motor.

According to one embodiment, the disinfection device has a compressed air connection and is set up to introduce compressed air into the flushing medium and / or the respective stationary line or the flushing line.

According to one embodiment, the measuring device comprises at least one flow sensor coupled to the control device for detecting a flow rate of the flushing medium on a respective fixed line and / or in the feed line and / or in the return, and / or the one time recording unit coupled to the control device. A respective flow sensor can also be used for a balance of the flushing medium, in particular in that the flow rate of at least two flow sensors is continuously recorded and compared. This enables monitoring with regard to line breakage or leakage.

According to one embodiment, at least two flow sensors are provided, which are arranged both in front of (upstream) and behind (downstream) the reservoir. This enables leaks to be identified. The control device is set up to detect and store a difference value between the flow rate detected by these flow sensors, in particular to create a flow balance. The control device is set up for a difference value above to interrupt a disinfection process at a threshold value.

According to one exemplary embodiment, the measuring device is set up for the autonomous acquisition of geographical data or the respective place of use (location), in particular by means of a read-out unit. Thanks to automatic location detection, incorrect entries or manipulation of the disinfection protocol can be ruled out. The control device can be set up to control or regulate a disinfection process as a function of location-specific data stored in the control device and / or entered by an operator, in particular location, line volume, line length. This facilitates the exact recording and documentation of location-related disinfection data, in particular with reference to a respective operating theater of a hospital. The readout unit can, for example, also comprise a GPS for the autonomous acquisition of absolute geodetic data. The acquisition of geographical data or location information can also take place, for example, by reading out a chip which is installed in a respective vestibule or in the immediate vicinity of an operating room. Not only location information or room information can be stored in the chip, but also information about the length or volume of a respective fixed line, for example.

It has been shown that the autonomous reading of data stored at the respective location is more advantageous than, for example, the use of a barcode scanner. On the one hand, handling is made easier, and on the other, sources of error can be avoided. For this purpose, the readout unit can have a transmitter / receiver unit with a predetermined range, in particular a few centimeters or meters, so that only the data stored at the place of use are read out. The range can be adjustable, in particular to facilitate handling and to adapt the range to the distance between stationary data carriers / chips. Thanks to the adjustable range, the risk of errors when reading can be minimized without unnecessarily restricting the handling or the operating range of the disinfection device. Nevertheless, the disinfection device can also comprise a barcode scanner coupled to the control device.

According to one exemplary embodiment, the control device is set up to create and save a disinfection protocol or test report based on recorded measured values. The disinfection device can have a display or output unit for displaying or outputting a disinfection protocol, in particular in paper form for visual documentation at the place of use of the disinfection device. A status report can also be output before the disinfection device starts the disinfection process. The control device is then set up to check the status of the disinfection device before the start of the disinfection of stationary lines and to output a status report or at least to save or output it together with a disinfection protocol. If the disinfection device has not been disinfected or has not been disinfected properly, or if the disinfection process has already passed a minimum duration greater than a predefinable time threshold value, a warning message can be output and / or the method for disinfecting stationary lines can be blocked. The disinfection process can then be blocked until the disinfection device itself has been (re) disinfected, in particular in accordance with the reprocessing process described here. This self-monitoring or self-diagnosis increases safety and reduces the risk of bacteria or germs entering the fixed lines by means of the disinfection device.

The aforementioned object is also achieved by a disinfection device for the thermal disinfection of fixed lines, with: a reservoir for rinsing medium, for disinfecting a respective fixed line; at least one feed line outgoing from the reservoir with an outlet for coupling the disinfection device to a respective stationary line; a heating device for providing the rinsing medium with a set temperature that is higher than room temperature, in particular at least 73 ° C .; a control device coupled to the heating device for setting, controlling and / or regulating a temperature of the flushing medium; at least one measuring device coupled to the control device for detecting at least one measured variable of the flushing medium, in particular a temperature; a return line for returning flushing medium from the stationary line back into the disinfection device with an inlet for coupling the respective stationary line to the return line; the disinfection device being independent of the flushing medium, the disinfection device being set up to form a disinfectable, hermetic circuit that is also externally arranged with respect to the disinfection device by means of the feed line and the return in connection with a respective stationary line, the reservoir being a hot reservoir for providing and holding flushing medium with a temperature of at least 73 ° C, the disinfection device being set up for purely thermal self-disinfection, and in particular also for self-diagnosis, the disinfection device having a cold container connected to the reservoir, the cold container is connected to the reservoir by means of a supply bypass, in particular a pipe open on both sides, which supply bypass has two free ends which protrude into the cold container and into the reservoir, in particular up to a predefined fill level, the supply bypass Open on both sides and valveless without valves, the disinfection device being designed as a mobile device, and the reservoir providing a volume for flushing medium corresponding to a multiple, in particular at least a factor of 3 to 5, of the volume of the respective stationary line. This results in many of the advantages mentioned above.

The disinfection device can be provided together with two, three or even more connecting hoses, which facilitate coupling of the disinfection device to a respective fixed line. Such a connection hose, e.g. made of silicone, can also be used to short-circuit or connect two stationary lines. Optionally, one end of the feed line or the beginning of the return line (or the inlet) can also be designed in the form of a flexible hose with a coupling.

The above-mentioned object is also achieved by using a flushing medium-autonomous disinfection device designed as a mobile stand-alone device without external flushing medium supply, in particular a disinfection device described here, for the thermal disinfection of inner surfaces of stationary lines. For this purpose, a reservoir with a volume of flushing medium with a multiple of the volume of the fixed line to be disinfected can be provided. This results in advantages already described above.

The above-mentioned object is also achieved by using a disinfection device designed as a mobile stand-alone device, in particular a disinfection device described here, for the purely thermal disinfection of fixed lines, the disinfection device automatically in a purely thermal manner independently of the flushing medium, without external flushing medium supply, before or after a disinfection process processed or disinfected (autonomous self-disinfection). This results in advantages already described above. Automatic sampling can also take place in at least one sampling container of the disinfection device.

The above-mentioned object is also achieved by using a flush-medium-autonomous disinfection device designed as a mobile stand-alone device for disinfecting the inner surfaces of fixed medical lines for hypothermic applications against mycobacteria without external flushing medium supply, in particular a disinfection device described here, the disinfection device being exclusively supplied with energy from outside. This results in advantages already described above.

The above-mentioned object is also achieved by using a disinfection device designed as a mobile stand-alone device, autonomous from the flushing medium, for the thermal disinfection of inner surfaces of medical lines for hypothermic applications against mycobacteria, in particular a disinfection device described here, in an anteroom to an operating room for disinfecting lines leading into the operating room , with flushing medium being taken from an external reservoir of the disinfection device without flushing medium supply and being returned to the disinfection device. A circulation for the flushing medium can be provided here. The flushing medium can optionally be guided in just one loop and / or in a circle. The flushing medium can be temporarily stored or buffered.

The above-mentioned object is also achieved by using at least one bypass open on both sides between two rinsing medium receiving containers of a disinfection device designed as a mobile stand-alone device for disinfecting fixed lines, in particular two bypass pipes for connecting three containers in series, for processing or disinfecting the disinfection device by means of flushing medium in the gas phase (autonomous self-disinfection) without external flushing medium supply, in particular in a disinfection device described here. This results in advantages already described above.

• - Einstellen wenigstens eines Wertes wenigstens einer Messgröße des Spülmediums oder wenigstens eines Verfahrensparameters, insbesondere eines Wertes für eine Soll-Temperatur und/oder einer Mindest-Spüldauer zum Desinfizieren der (jeweiligen) ortsfesten Leitung, oder Abrufen des wenigstens einen Wertes aus einem Speicher der Desinfektionsvorrichtung, insbesondere eines Wertes abhängig vom Einsatzort der Desinfektionsvorrichtung, z.B. das Innenvolumen der zu desinfizierenden ortsfesten Leitung;
• - Erfassen wenigstens eines Messwertes und Regeln wenigstens einer Messgröße des Spülmediums, wobei der Messwert und die Messgröße jeweils zumindest eine Temperatur des Spülmediums im Reservoir umfassen;

• - Aufzeichnen und Abspeichern von erfassten Messwerten umfassend Ist-Temperaturen des Spülmediums an einem Rücklauf der Desinfektionsvorrichtung oder von der Dauer des Spülens.

The above-mentioned object is also achieved by a method for the automated disinfection of inner surfaces of fixed lines, in particular medical-technical lines, by using a disinfection device designed as a mobile stand-alone device, with the steps:

• - Setting at least one value of at least one measured variable of the rinsing medium or at least one process parameter, in particular a value for a target temperature and / or a minimum rinsing duration for disinfecting the (respective) stationary line, or retrieving the at least one value from a memory of the disinfection device , in particular a value depending on the place of use of the disinfection device, for example the internal volume of the fixed line to be disinfected;
• - Acquiring at least one measured value and regulating at least one measured variable of the flushing medium, the measured value and the measured variable each comprising at least one temperature of the flushing medium in the reservoir;
• - Autonomous disinfection without rinsing medium supply from external by automatically introducing rinsing medium at a target temperature of at least 73 ° C from the reservoir into the fixed line and returning the introduced rinsing medium from the fixed line back to the disinfection device;
• - Recording and storage of recorded measured values including actual temperatures of the rinsing medium on a return line of the disinfection device or of the duration of the rinsing.

• - Bereitstellen einer Desinfektionsvorrichtung mit einem Reservoir beinhaltend Spülmedium an wenigstens einer ortsfesten Leitung;
• - Anschließen sowohl wenigstens eines Auslasses als auch wenigstens eines Einlasses der Desinfektionsvorrichtung an die (jeweilige) ortsfeste Leitung.

Before setting or calling up measured variables or measured values, the following steps can also be carried out, be it manually, be it automatic or motorized:

• - Provision of a disinfection device with a reservoir containing rinsing medium on at least one stationary line;
• - Connecting both at least one outlet and at least one inlet of the disinfection device to the (respective) stationary line.

The disinfection of lines includes the disinfection of inner surfaces or of elongated narrow cavities with a large length-to-width ratio.

In an advantageous manner, each stationary line is disinfected separately. Several fixed lines are then disinfected chronologically one after the other. This means that a disinfection can be certified for each line. There is no risk of measurement results being assigned incorrectly. Optionally, several fixed lines can also be coupled together in series in order to disinfect them together. However, only one cycle is created: The flushing medium runs through all the lines before it is directed into the return tank.

According to a variant, several separate stationary lines can also be disinfected. Each stationary line is connected to an outlet and an inlet of the disinfection device. In other words: for each stationary line, the disinfection device has at least one outlet and one inlet. Furthermore, a separate sensor system can be provided for each stationary line or each circuit provided for it. This enables time-efficient, synchronous disinfection of several lines, whereby a specific disinfection program can be run through for each of the lines. In practice, this can save a lot of time, especially because there is no need for cooling phases.

The connection can take place, for example, by means of standardized couplings that seal on both sides, in particular in a fluid-tight manner.

Before or after the connection, the disinfection device can be activated by supplying electrical energy. Electrical energy can be supplied from an internal energy store and / or via an external power line.

The disinfection can include the execution of a disinfection process or disinfection program. A respective disinfection program can be stored in a data or program memory of the disinfection device. The disinfection or rinsing can also include a static lingering of the rinsing medium in the line, in particular during a predetermined period of time.

The introduction and return can in each case take place in such a way that the flushing medium is not circulated, but is only passed once through the line. This can also be done repeatedly with predefined volumes, the volumes being able to be specified as a function of the line volume to be flushed, for example 1.5 times the volume. A minimum dwell time can also be specified for each rinsing cycle, be it with flow, be it in a static state with a volume flow equal to ZERO.

The flushing duration is to be understood as meaning, in particular, a dwell time of flushing medium in the respective stationary line. Optionally, a flow rate can also be recorded and regulated. The recording of measured values can include recording the measured values and forwarding them to a control device.

The disinfection process can be ended by decoupling the disinfection device from the inlet or outlet. Couplings that seal on both sides can be used so that prior pumping out of the stationary line is not necessary. The line can remain filled.

According to one embodiment, the step of detecting and regulating comprises detecting a temperature at the inlet and the return line as well as a flow through the feed line and regulating a flow through the Feed line, in particular such that the temperature at the return is greater than or equal to 73 ° C and a difference between the temperature at the inlet and the temperature at the return is less than 5 ° C. Such a comparatively small difference can ensure that all line sections have essentially the same energy applied to them. The disinfection process is carried out comparatively homogeneously, in particular in a very controlled manner. Last but not least, this also minimizes the thermal load on the fittings.

According to one embodiment, a rinsing medium volume is held in a reservoir of the disinfection device, which is at least a factor of 3, in particular a factor of 3 to 5 greater than the internal volume of the fixed line to be disinfected, the rinsing medium being / is heated to a temperature which is higher than the minimum temperature (target temperature) to be maintained for disinfection. The temperature difference can be in the range of 5 to 10 ° C, for example. This can ensure that flushing medium returned to the reservoir does not cool the flushing medium held in the reservoir too much. A comparatively large energy buffer enables the desired minimum temperature (in particular 73 ° C) to be maintained, even at comparatively high flow rates. It has been shown that a volume that is 3 to 5 times larger provides a good compromise between handling the device and the energy content held ready.

According to one embodiment, the disinfection takes place in a purely thermal manner at target temperatures of at least 73 ° C., with the creation and storage of a disinfection protocol or test report based on recorded measured values including at least temperature values. The actual temperature is recorded at least also at the inlet or in the return. The actual temperature can be recorded, documented or output for checking in particular with regard to the return flow. A temperature higher than the minimum temperature can be set on the reservoir or on a feed line, in particular 1 to 10 ° C higher. The temperature on or in the feed line can be set and regulated by adding heating power or regulating the flow rate in such a way that at least the minimum temperature is present on the return line.

Water is advantageously used as the rinsing medium, in particular additive-free water of drinking water quality. This makes it possible to certify the fixed, in particular medical-technical lines, after disinfection has taken place, at least as clean as the drinking water quality. “Additive-free water” is to be understood as water to which no further, in particular chemical agents have been added for the purpose of disinfection. Disinfection can only be carried out thermally. The rinsing medium can be present exclusively in the liquid phase or also partially in the gas phase. The rinsing medium can be at least partially in the gas phase, that is to say also completely in the gas phase, at least temporarily during individual time segments of a disinfection process. By purging with the gas phase, disinfection can be carried out in a comparatively efficient or effective manner. According to a variant, the flushing medium used can also be completely in the gas phase, in particular for the purpose of self-disinfection.

According to one embodiment, the disinfection takes place by means of flushing medium in the form of water in the liquid and / or gas phase, in particular additive-free water with at least drinking water quality, in particular with at least temporarily continuous flushing medium volume flow. Disinfection can take place with flushing medium with a certain volume flow, in particular also with a continuously sustained constant volume flow. A continuously sustained, for example constant, flushing medium volume flow can enable good monitoring or control of the disinfection process.

According to a variant, the volume flow is varied for certain periods of the disinfection process. Then disinfection takes place with at least two predefined volume flows.

According to one embodiment, the introduction of flushing medium also includes flushing the stationary line with flushing medium from the reservoir or from a cold container of the disinfection device, in particular before and / or after the disinfecting step. The flushing can optionally take place at the target temperature or a lower temperature, in particular also at room temperature. During flushing, the flow rate can also be recorded, in particular to determine the volume of the fixed line.

According to one embodiment, the flushing takes place with flushing medium in the form of fresh water from the cold container, the stationary line being completely filled with fresh water. In this way it can be ruled out that air remains in the stationary line.

According to one embodiment, after completion of the disinfecting step, a temperature control is carried out on a return of the disinfection device, with an inlet of the disinfection device connected to the return being released when the temperature falls below a maximum. Releasing the inlet can also provide protection against scalding. The release can take place, for example, by or in conjunction with an acoustic signal. The release can include an unlocking of a coupling provided at the inlet. A release thus facilitates handling, even for untrained operators of the disinfection device.

If stationary medical technology lines have to be disinfected in a heart clinic, the operator can also be a cardio technician. This is usually trained. Nevertheless, easy handling is also advantageous for the cardio technician.

The aforementioned object is also achieved by a method for processing a disinfection device designed as a mobile standing device set up for disinfecting stationary lines, in particular a disinfection device described here, in particular in connection with or in chronological order with a method described here for disinfecting stationary lines, wherein purely thermal disinfection of flushing medium-carrying components of the disinfection device by means of flushing medium held ready in a reservoir of the disinfection device without external flushing medium supply, in particular in the gas phase (self-disinfection), and with the acquisition and storage of measured values characterizing the disinfection process including at least one temperature of the rinsing medium or the components (self-diagnosis) takes place, in particular also the duration of the thermal disinfection.

The reprocessing process can be part of the disinfection process. The disinfection method can include the processing method, in particular chronologically after the disinfecting step.

The disinfection is preferably carried out in a purely thermal or non-chemical manner without chemicals, that is to say free of chemicals. Purely thermal disinfection of such devices has not been possible up to now, in particular due to regulations. For example, hypothermia devices must not be technically capable of generating temperatures of over 40 ° C. Purely thermal disinfection also has the advantage that there is no risk of chemical residues.

There is a risk of chemical residues. In many cases, disinfection is required for a period of around one month. In other words: a disinfection process must be carried out every month.

According to one embodiment, the method furthermore also comprises the step of emptying a cold container of the disinfection device; during thermal disinfection, rinsing medium in the gas phase is fed from the reservoir via an open supply bypass into the cold container and optionally also via an open discharge bypass into a return container of the disinfection device, in particular without switching valves and by a vapor pressure generated in the reservoir. This enables a robust, reliable process which, not least, can also be carried out in an energy- and time-efficient manner.

• - Erstellen und Abspeichern eines Desinfektions-Protokolls bzw. Prüfberichts basierend auf den Messwerten. Der Prüfbericht kann durch Ausdruck oder Anzeige auf einer Anzeigeeinheit der Desinfektionsvorrichtung kenntlich gemacht werden.

According to one embodiment, the method for processing further comprises the steps:

• - Emptying a reservoir and / or a return container and / or a cold container of the disinfection device;
• - At least partial filling of the reservoir and / or return tank and / or cold tank with fresh, unused rinsing medium or fresh water;
• - thermal disinfection of at least the reservoir and return tank and optionally also the cold tank or other components of the disinfection device carrying rinsing medium at a temperature of the components of at least 73 ° C;
• - Detecting at least one measured value and regulating at least one measured variable of the rinsing medium, in particular the temperature of the rinsing medium and / or the temperature in or of the reservoir, return tank or cold tank or the temperature of at least one of the further components;
• - Recording of measured values and storage of recorded measured values, in particular the duration of the thermal disinfection and / or at least one temperature of the rinsing medium;
• - Creation and storage of a disinfection protocol or test report based on the measured values. The test report can be identified by a printout or display on a display unit of the disinfection device.

According to one embodiment, the reservoir and / or the return tank are filled or rinsed with cold rinsing medium or rinsing medium at room temperature, in particular cold water, in particular in each case before emptying. This allows the disinfection device to be cooled, in particular in a time-efficient manner.

According to one embodiment, only water of drinking water quality is fed to the disinfection device or only electrical energy and water of drinking water quality. This enables a strong autonomy. A water and / or power connection can be sufficient so that the disinfection device can be disinfected almost independently of location.

According to one embodiment, the disinfection is carried out at a pressure corresponding to the ambient pressure or ambient pressure increased by up to 20 mbar.

According to one embodiment, the thermal disinfection is carried out by means of flushing medium in the gas phase by directing flushing medium in the gas phase from the reservoir into a cold container and into the return container, in particular when the reservoir, return container and cold container are openly connected in series. Disinfecting using the gas phase enables a high level of efficiency and safety. All containers or fittings of the disinfection device carrying the flushing medium can be connected in series. This ensures that all of these components are disinfected equally. The recording of the temperature of the flushing medium in the gas phase downstream of all components enables reliable control of the treatment process.

According to one embodiment, the thermal disinfection is carried out within a time of less than 120 minutes, in particular less than 90 minutes. carried out, in particular without additives by means of flushing medium in the gas phase.

According to one embodiment, during disinfection and / or preparation, a sampling step is also carried out by introducing flushing medium into a sampling container of the disinfection device. In this way, reliability and control options or documentation options can be further improved.

In a cold container 40 there is a fill level z40 or. z40a , z40b in front of, which is above or below the level height z2 depending on the operating status. When disinfecting fixed lines is in the cold container 40 a level above the height z2 before, so that the second free end 15.2 is arranged in the flushing medium or cold water and forms a type of hydrostatic barrier (first fill level z40a ). With an automated self-disinfection of the disinfection device 10 can the cold container 40 be completely empty, or the level will at least be below the height z2 held (second level z40b ), so that the gaseous flushing medium enters the cold container 40 can get.

In 2 is an operating state with one level z40a shown with which flushing medium from the reservoir 20th not in the cold container 40 can reach, neither in the gas phase nor in the liquid phase, at least not via the supply bypass 15th . Its second free end 15.2 is from flushing medium or cold water MK surrounded so that a hydrostatic barrier is formed.

3 shows an operating state during device preparation. The disinfection device 10 disinfects itself, especially fully automatically with documentation. In the reservoir 20th there is a comparatively small volume of flushing medium in the liquid phase. The flushing medium surrounds the heating elements 16.1 , 16.2 , is heated, evaporated, passes through the open supply bypass 15th and gets into the cold container 40 . There has to be flushing medium in the gas phase from the second free end 15.2 to the first free end 17.1 a flow path SPz with a length corresponding to the distance between the two free ends. The free ends 15.2 , 17.1 can be arranged so that the vertical flow path SPz is as long as possible, in particular at least 2/3 the extension of the cold container 40 in this direction. The second free end can be used for this 15.2 in the lower third of the cold container 40 be arranged, and the first free end 17.1 can be arranged in the upper third of the cold container. This can ensure that the rinsing medium in the gas phase heats the cold container comparatively homogeneously and reliably disinfects it. Furthermore, from the discharge bypass 17th the function of an overflow for liquid flushing medium in the backwater tank can be fulfilled. When heating the cold container 40 condensate can build up K form which over the line 34 the return tank 30th can be fed. The relative position of the free ends 15.2 , 17.1 to each other and in relation to the dimensions of the cold container 40 thus enables comparatively homogeneous heating and steaming without the need for complex control or circuit technology. Condensate can run through the drain 32 be drained. The lines 32 , 24 and 34 can each at the lowest point of the corresponding container 20th , 30th , 40 be arranged. The containers 20th , 30th , 40 can each have an outlet at the lowest point, to which the respective line 32 , 24 , 34 connected. This allows the system to be drained without pumping.

The sampling line 35 is with the rewind 14th and the reservoir 30th connected and can be opened or closed by means of a (motor) valve M. To the valve M. can have at least one sampling container 36 be coupled. A control device can specify that a sample is taken automatically, in particular as a function of a time or as a function of the course of a disinfection process. For this purpose, the control device can use the corresponding valve M. control, for example open one minute shortly before the end of the disinfection process, so that the used flushing medium enters the sampling line 35 can flow. At the sampling line 35 a flow sensor can also be arranged. Then, after a minimum volume has flowed through, the valve can M. closed again automatically. Optionally, the valve M. be opened by default for a predefined or specifiable period of time.

the 4th shows an arrangement comparable to that of FIG 1 until 3 . In 4th is the return tank 30th to the right of the reservoir for the sake of clarity 20th shown. In addition, there is an appropriate position for each of temperature sensors 62 and flow sensors 64 (which can also include temperature sensors) and level sensors 69 shown. There is also a compressed air connection 11.2 on the feed line 12th indicated. On every container 20th , 30th , 40 are at least one temperature sensor 62 and a level sensor 69 arranged.

5 shows further components of a disinfection device 10 . The supply line 11th can have a connection 11.1 for flushing medium can be connected to a stationary supply line or a connecting hose (each not shown). There is also a compressed air connection 11.2 as well as a power connection 11.3 intended.

An output unit 90 , in particular a printer or a printer unit enables test reports to be documented, in particular in paper form.

6th shows steps of a method for the automated disinfection of inner surfaces of fixed lines. In a preparatory step S0 a displaceable disinfection device can be provided. In a first step S1 An outlet or an inlet can be connected, in particular by coupling by means of couplings that seal on both sides. In a second step S2 at least one value or parameter can be set or retrieved, in particular automatically or by an operator. For example, location-specific information such as the length of the fixed line or its volume can be entered or retrieved. In a third step S3 A measured value can be recorded or a measured variable can be regulated, in particular by a plurality of sensors and the control device. In particular, the heating power can also be regulated based on one or more temperature measured values. In step S3 For example, the temperature at the inlet can be recorded. It has been shown that a temperature at the inlet in the range from 74 ° C. to 78 ° C., in particular 74 ° C. to 76 ° C., especially 75 ° C., can be sufficient to cover the entire respective fixed line 5 to disinfect. For this purpose, the flow rate can also be regulated, for example in the range of 10-40L / min., Especially in the case of a line with a diameter of, for example, 15-35mm.

A not too high temperature at the inlet or a comparatively high flow rate provides several advantages. On the one hand, the energy requirement is comparatively low. On the other hand, the fittings are subjected to comparatively little stress. The disinfection device can be set up to maintain a temperature gradient of, for example, max. 4 or 5 ° C in circulation.

In a fourth step S4 The respective stationary line can be disinfected independently of the flushing medium, in particular in a purely thermal manner without chemical additives. The step S4 can, for example, be carried out using a disinfection temperature of up to 95 ° C. In one step S4a flushing can take place, in particular immediately before and / or after the disinfecting step. In one step S4b sampling can take place, in particular fully automatically. In a fifth step S5 recording and saving of measured values can take place. In one step S5a a measured value check can be carried out, in particular after the step S4 or S4a . In one step S5b A disinfection protocol or test report can be created and saved based on the measured values recorded.

The individual steps can be integrated into the process sequence independently of one another, in particular also in an order that differs from the order shown, e.g. also synchronously.

In a first point of regulation R1 the coupling at the inlet or outlet can be checked, in particular by means of contact sensors on a respective coupling part. In a second regulation point R2 can control an operator input or a plausibility check, in particular by comparing the operator input with stored values. In this way, site-specific data read out fully automatically from a stationary chip can also be verified. In a third regulation point R3 at least one measured variable can be regulated, in particular at least also the time or a temperature. A control device can be coupled to sensors provided in this context in order to carry out the corresponding regulation. The control points can be integrated into the process sequence independently of one another, in particular also in an order that differs from the order shown, for example also synchronously.

7th shows steps of a method for processing a previously described disinfection device set up to disinfect stationary lines, in particular in connection with or in chronology with a previously described method for the automated disinfection of inner surfaces of stationary lines. In a first step S11 the reservoir, a container and / or a fitting of the disinfection device can be emptied. All containers are preferably emptied. In this way it can be ensured that the containers can also be brought completely to a comparatively high temperature by means of steam or flushing medium in the gas phase. In a second step S12 an at least partial filling with fresh, unused flushing medium can take place, in particular excluding the reservoir 20th .

In a third step S13 the disinfection device can be thermally disinfected, in particular by means of a flushing medium in the gas phase. For this purpose, the flushing medium can be heated to a target temperature of 102 ° C., for example, in particular in the reservoir. It has been shown that the evaporation of approx. 2L of flushing medium can be sufficient for resilient, reliable self-disinfection. In this way, a steam volume of approx. 3,500L can be generated, corresponding to, for example, the factor 10 larger volume than the internal volume of the containers or fittings to be disinfected. The flushing medium is preferably generated in the gas phase in the reservoir, in particular by means of a heating device comprising at least one heating element arranged on or in the reservoir. The reservoir or the rinsing medium can be heated to a temperature above 100 ° C, for example 102 ° C. This can ensure that the gas phase is generated. The transition point from the liquid phase to the gas phase is dependent on the absolute pressure. At a location at an altitude of 2,500 m, for example, the flushing medium passes into the gas phase well below 100 ° C. The target temperature for the flushing medium in the gas phase in the reservoir can therefore be set. Nonetheless, a temperature of at least 102 ° C is recommended, especially in order to supply the flushing medium with sufficient energy to be able to heat the entire container and fittings to over 80 ° C. This provides a high level of security with regard to the effectiveness of the disinfection process.

In one step S13a it can be filled or flushed with cold flushing medium. In one step S13b sampling can take place, in particular fully automatically. In a fourth step S14 a measured value can be recorded or at least one measured variable is regulated, in particular at least also the time or a temperature. In a fifth step S15 recorded measured values can be recorded and saved. In one step S15b A disinfection protocol or test report can be created and saved based on the measured values recorded.

The individual steps can be integrated into the process sequence independently of one another, in particular also in an order that differs from the order shown, e.g. also synchronously.

In a first point of regulation R11 the level can be checked, especially in the reservoir. In a second regulation point R12 The filling volume can be recorded and set, in particular by reading out a filling level sensor which detects a minimum filling level required for self-disinfection, for example 5 to 10L. In a third regulation point R13 at least one measured variable can be regulated, in particular at least also the time or a temperature. A control device can be coupled to sensors provided in this context in order to carry out the corresponding regulation. The control points can be integrated into the process sequence independently of one another, in particular also in an order that differs from the order shown, for example also synchronously.

The one in the 7th and 8th The method steps described can be combined with one another, in particular carried out chronologically one after the other. A combined process can optionally be carried out with the steps S0 , S1 , ... or with the steps S11 , S12 , ... start. Optionally, a time programming can also be carried out. For example, a time of day can be specified at which the disinfection device is to start self-disinfection. This can facilitate the use of the disinfection device in a state that is as completely sterile as possible. In particular, the point in time for fully automatic self-disinfection can be specified in such a way that the disinfection device is available again shortly before a period in which fixed lines can be disinfected. In a clinic, for example, this has to be done at night between 11 p.m. and 5 a.m.

Based on 8th is a place of use for the disinfection device 10 explained in a clinic. The disinfection device 10 is in an anteroom 3 arranged, which is to a so-called introduction room 2 (Introduction) that adjoins an operating room 1 leads. There is also a separate area from these rooms 4th indicated for a device reprocessing, in which the disinfection device 10 can be turned off, especially for the purpose of self-disinfection. Between the anteroom 3 and the operating room 1 four fixed lines run 5 , especially laid in the wall (under the plaster) or in the floor structure. Any line 5 has first and second open ends 5.1 , 5.2 or a coupling arranged there. Any line 5 provides an input (IN) 7th and one output (OUT) 8th ready. At the entrance 7th can for example be supplied with drinking water and at the exit 8th in the operating room 1 can be removed.

The input (IN) 7th assumes the function of an inlet to the fixed line 5 during the disinfection process. The actual function of the entrance 7th can remain unaffected by this. The same applies to the output (OUT) 8th the fixed line. Depending on how several lines 5 are coupled to each other, the input (IN) and the output (OUT) can change.

The open ends 5.1 , 5.2 can be done in pairs by means of a connecting hose 6th connected together so that all four lines 5 together form a long line. Then you are in the operating room 1 two connecting hoses 6th on two lines each 5 coupled, and in the anteroom 3 is a connecting hose 6th on two lines 5 coupled. From the entrance 7th can flush medium in the direction of the outlet 8th flow, there in the connecting hose 6th be diverted and into another line 5 be directed to finally at the coupling point 5.2 to be brought back again.

The disinfection device 10 can comprise or have ready two or three hoses, by means of which the disinfection device 10 on two of the lines 5 can be coupled. These hoses can be the connecting hoses 6th or as part of a feed line or a return line.

Although at least one exemplary embodiment has been described in the preceding description, various changes and modifications can be made. The at least one described exemplary embodiment is only described as an example and is not intended to restrict the scope, applicability or configuration in any way. Rather, the preceding description provides the person skilled in the art with a plan or a technical teaching for implementing at least one exemplary embodiment, it being possible to make numerous changes in the function and arrangement of elements or features described by way of example without the scope of protection of the claims or legal equivalents listed to leave.
