Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the connection and connection of medical instruments.
The present invention relates to an automatic exchange apparatus for automatically performing detachment, and more particularly to an automatic exchange apparatus for peritoneal dialysis provided with a sterilizing means for preventing contamination and infection when connecting and exchanging a connector for peritoneal dialysis.

[0002]

2. Description of the Related Art Peritoneal dialysis therapy has been used as an excellent renal failure therapy because the bag can be exchanged at home or the like and does not involve extracorporeal blood circulation. In addition, since the cost is lower than that of hemodialysis therapy, it is a promising method in the medical field where medical cost reduction is required.

[0003] However, this therapy has a problem of contamination and infection due to operation mistakes and carelessness, because the patient or his or her caretaker must replace the bag and detach the connector. Even ordinary patients need to attach and detach connectors with great care. However, many dialysis patients are unable to follow their eyes and limbs, and cannot follow up sufficiently.

For this reason, recently, a device for automatically replacing a connector has been devised. With the above-mentioned device, it is possible to reduce contamination and infection due to operation errors and carelessness. However, the sterilizing means and the automatic exchange device without the sterilizing means merely substitute for a part of the manual operation of the patient (caregiver), and the problems of contamination and infection still remain. For example, it is a countermeasure against erroneous operation before being attached to the automatic exchange device, care for contamination and infection due to carelessness, and assurance of sterility inside the automatic exchange device.

[0005] However, the provision of the sterilizing means in the automatic connector changing apparatus has various problems and limitations as described below, and the means is also limited. That is, (1) the human body may be harmed by the sterilization / sterilization means. (2) The sterilization and sterilization effect is required in a short time. (3) Unless the device is simple and compact, it is inconvenient to carry. (Four)
Long-term use may cause deterioration of the material inside the device.

[0006]

For example, a disinfectant such as isodine has been widely used as a disinfection method before an automatic exchange device was considered. However, there have been problems such as that it is difficult for isodine to fall off once it adheres, and the effect of mixing isodine into the abdominal cavity has not been confirmed. Also,
In addition, products that melt and fuse tubes together with sterilization by heat have been commercialized.

[0007] However, this device is not simple in structure, and there remain problems such as limitations on tube specifications, difficulty in downsizing the device, and an increase in cost. In addition, sterilization means by ozone, sterilization means by microwave irradiation, etc. have been devised, but all are widely spread in terms of simplicity of structure, increase in cost, and reliable sterilization effect by short time treatment. Not.

[0008] The most common sterilization method that has been put to practical use in peritoneal dialysis exchange devices is ultraviolet irradiation.
However, this sterilization method has a drawback that there is no (sterilization) effect in a portion where light has not reached, and that the material inside the device is deteriorated due to frequent use. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an automatic connector changer provided with a sterilizing means so that the above-mentioned problems can be solved.

[0009]

SUMMARY OF THE INVENTION The present invention relates to an automatic exchange device for a peritoneal dialysis connector having a sterilization means, wherein the sterilization means is a cylindrical ultraviolet irradiation lamp, and wherein the automatic exchange device includes a patient. The connector and the bag connector are mounted so as to be substantially parallel, and the ultraviolet light is disposed between the patient connector and the bag connector, and the connection between the patient connector and the bag connector (in a direction perpendicular to the connector axis).
Peritoneal dialysis, characterized in that the opening end of the patient connector faces the ultraviolet irradiation lamp by relative movement, the ultraviolet irradiation lamp is inserted into the lumen of the patient connector from the opening end, and the interior of the patient connector is irradiated with ultraviolet light. The above problem has been solved by an automatic exchange device.

[0010] In peritoneal dialysis, the possibility of contamination or infection is high during the detachment operation between the patient connector and the bag connector or the detachment operation between the caps of the connectors, and the time to open the connector end is prolonged. The greater the risk of contamination. In the present invention, by disposing an ultraviolet irradiation lamp as a sterilizing means in the vicinity of the both connectors, by sterilizing with ultraviolet light before connecting the two connectors,
Quick and reliable sterilization can be performed after opening the connector. In addition, by inserting and irradiating an ultraviolet irradiation lamp into the connector lumen, a sterilizing effect can be improved,
It is also possible to protect against contamination on the inner side of the connector (which directly causes contamination and infection).

As a further advantage, since the ultraviolet irradiation is performed in the connector cavity, deterioration inside the connector exchange device due to the ultraviolet irradiation can be suppressed. It is possible to adopt a material that is difficult to transmit ultraviolet light as the material of the connector, and by selecting a material with low UV transmittance,
It is possible to suppress not only the inside of the connector exchange device but also the deterioration of the connector itself. This is a great advantage for a patient connector that has to be used for a certain period of time. As described above, in the past, in order to improve the sterilizing effect of the connector lumen, high UV transmission performance was required for the connector material, but in the replacement device of the present invention, since the ultraviolet irradiation lamp is inserted into the connector lumen, It is not necessary to select a material having high transparency as a material of the connector.

Also, after connecting both connectors (for filling and draining), the connectors are detached and caps are attached to each connector again, but before the patient connector cap is attached to the patient connector, the patient connector inner cavity is again attached. Insert an ultraviolet light into the
By irradiating the inside of the connector, a sterilizing effect can be further improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Various preferred embodiments of the present invention will be described below. In general peritoneal dialysis, the patient connector 2 is, as shown in FIG.
And the patient connector cap 2b (hereinafter, also referred to as a patient side cap). The bag connector 3 includes a bag connector main body 3a and a bag connector cap 3b.
Prior to mating of the patient and bag connectors, each cap is removed from both connectors.

One embodiment of the present invention is a switching device as shown in FIG. This automatic exchange device has a first mounting table 4 on which the patient connector main body 2a is mounted, and a second mounting table 5 on which the bag connector main body 3a and the ultraviolet irradiation lamp 1 are mounted. As shown in the drawing, the first mounting table 4 and the second mounting table 5 are arranged to face each other, and the patient connector main body is connected to the ultraviolet irradiation lamp by either or both of the above-mentioned mounting tables and relative movement thereof. Face-to-face (FIG. 3), the interior of the patient connector is illuminated with ultraviolet light (FIG. 4).

Here, the patient connector cap 2b is
When mounted on the mounting table 5 and the bag connector cap 3b is mounted on the first mounting table 4, the cap is attached to and detached from each connector, the connectors are connected to each other (patient and bag), and ultraviolet irradiation is performed. The moving mechanism becomes simple.

The relative movement between the two mounting tables is shown in FIG.
Two types, one parallel to the connector axis (moving in the left-right direction) as shown in 4, 5 and 7, and one vertical (moving in the vertical direction) to the connector axis as shown in FIGS. There is. By the former movement, the caps 2b and 3b of the patient connector 2a and the bag connector 3a are detached from the caps 2b and 3b, and by the movement of the latter, the patient connector main body 2a and the ultraviolet irradiation lamp 1 or the bag connector main body 3a face each other. .

Further, in the above automatic exchange device for peritoneal dialysis, before the relative movement between the patient connector and the bag connector, the patient side cap is detached from the patient connector, and the bag connector cap is detached from the bag connector. The caps of the two connectors are detached substantially simultaneously.

In order to keep the patient connector 2 aseptic, it is desirable to remove the cap immediately before sterilization. However, if the patient connector cap is to be detached or moved after the patient connector 2 faces the ultraviolet irradiation lamp, the destination of the cap is restricted, and (with each connector and cap)
A moving mechanism for facing and a moving mechanism for removing each cap are separately required, which is uneconomical.

Therefore, as shown in FIGS. 1 and 2, the ultraviolet irradiation means 1 is placed between the connector mounting portions, and each connector is moved parallel to the cap in the axial direction and detached.
3, the patient connector main body 2a and the bag-side cap 3b are moved in a direction perpendicular to the axis and relatively displaced to the patient-side cap 2b and the bag-side connector main body 3a.

Here, the patient connector mounting portion and the bag side cap mounting portion are provided on the first mounting table 4, and the patient side cap mounting portion and the bag side connector mounting portion are provided on the second mounting table 5, and at least one of them is provided. By adopting a structure in which the mounting table can be moved in parallel and perpendicular to the axis, the attachment and detachment of each connector to and from the cap can be saved.
As a result, it is not necessary to individually move and control each of the mounting portions, and the structure is simplified and the cost can be reduced. With the above embodiment, the detachment of the cap from both connectors occurs substantially simultaneously. This is preferable from the viewpoint of shortening the opening time of the connector end.

The second embodiment of the present invention relates to an automatic peritoneal dialysis exchange apparatus as shown in FIG. 15, wherein the outer diameter D1 of the ultraviolet irradiation lamp 1 is 0.6 to 0.9 times the inner diameter D2 of the patient connector. It is. When D1 is within the above range, it is easy to insert the ultraviolet irradiation lamp into the inner cavity of the patient connector, and it is possible to select one that does not significantly decrease the ultraviolet irradiation ability as compared with a large diameter one.

A third embodiment of the present invention is the above-mentioned automatic exchange device for peritoneal dialysis in which 60 to 90% of the ultraviolet irradiation part of the irradiation lamp is inserted into a patient connector lumen. Many of the currently used patient connectors are of the double-cylinder type as shown in the figure. In this type of connector, a portion where the sterilization process is particularly desired is a region from the opening end 2c of the outer cylinder to the opening 2d of the inner cylinder of the patient connector as shown in FIG. And, it is desirable that most of the irradiation part of the irradiation lamp is present in the above-mentioned region of the patient connector lumen. If the irradiating section is larger than the above-mentioned region, the exposure of the connector exchanging device to ultraviolet rays becomes a problem.
Contaminated (potentially) portions of the connector connection may not be sufficiently sterilized.

As shown in FIGS. 4 to 7, a fourth embodiment of the present invention irradiates the inside of the patient connector with ultraviolet rays and then moves the first mounting table 4 to remove the patient connector (main body) 2a which is not at the facing position. Displace the bag connector (body) 3
a, and the two connectors are connected. Then, the connection is maintained for a predetermined time required for draining and injecting the liquid, and thereafter, the relative position of both connectors is displaced, so that the patient connector (main body) 2a faces the patient side cap 2b, It connects the two. That is, after the two connectors are connected, the order of the steps is reversed, and the steps are as shown in FIG. 7 → FIG. 6 → FIG. 2 → FIG. In this case, it is preferable to prepare a new cap separately from the old cap before detachment, instead of the old cap before detachment.

As shown in FIGS. 4 to 6, after irradiating the inside of the patient connector with ultraviolet rays, the first mounting table 4 is moved to the right side in parallel with the (connector) axis, so that the patient connector is moved from the ultraviolet irradiation lamp. keep away. In addition, the patient connector 2a and the bag connector 3a face each other by moving the mounting table 4 downward (displacement), and further, both connectors are connected by moving parallel to the axis of the mounting table 4.

After the connection, after draining the stored liquid from the body and injecting the dialysate into the body for a predetermined period of time, the patient connector 2a and the bag connector 3a are detached in the reverse of the connection, and the first mounting table 4 is moved. The patient connector 2a and the patient connector cap 2b are displaced by being moved upward (in the direction perpendicular to the connector axis) so that the patient connector 2a and the patient connector cap 2b face each other. In the above example, by moving only the first mounting table 4,
Although the position of each connector is relatively moved, only the second mounting table 5 may be moved instead, or both mounting tables may be moved.

After the dialysate is injected and drained and before the patient connector cap 2b is attached to the patient connector 2a, the automatic exchange device of the present invention is provided with a mechanism for irradiating the inner cavity of the patient connector once more with ultraviolet rays. Is also good. As shown in the drawing, in addition to the steps of FIG. 7 → FIG. 6 → FIG. 2 → FIG. 1, FIGS. 5 to 3 are added, and FIG. 7 → FIG. 6 → FIG. 5 → FIG. 4 → FIG. 3 → FIG. The order is as follows.

After the two connectors are connected to each other and the liquid is poured and drained for a predetermined time (FIG. 7), the mounting table 4 is detached in parallel with the axial direction, and the facing patient connector 2a and bag connector 3a are moved perpendicularly to the axis. Relative movement (displacement). The displacement causes the patient connector to face the ultraviolet irradiation lamp 1 and moves the patient connector in parallel to the axis, so that the connector 2a
The ultraviolet irradiation lamp 1 is inserted therein (FIGS. 5 and 4). After irradiation,
By moving the patient connector 2a away from the ultraviolet irradiation lamp 1 (FIG. 3) and displacing the first mounting table 4 upward, the patient connector 2a faces the patient connector cap 2b,
Connect the two close together. (Figs. 2 and 1)

Further, an automatic exchange device as shown in FIGS. 8 to 14 is also useful. It has a plurality of ultraviolet irradiation lamps 1a and 1b, and at least one pair of the irradiation lamps is arranged in a facing position, and when one of the ultraviolet irradiation lamps 1a is inserted into the lumen of the patient connector 2a, the other ultraviolet irradiation lamp 1a is irradiated. The automatic exchange device for peritoneal dialysis as described above, wherein the light 1b is inserted into the inner cavity of the bag connector 3a.

As shown in FIG. 8, the automatic exchange apparatus includes one of the ultraviolet irradiation lamps 1b, the first mounting table 4 on which the patient connector main body 2a is mounted, the bag connector main body 3a, and the other 1a of the ultraviolet irradiation lamps. Mounting table 5 on which is mounted
Respectively. The first mounting table 4 and the second mounting table 5 are arranged to face each other, and the patient connector main body 2a faces the ultraviolet irradiation lamp 1a due to the relative movement of one or both of the mounting tables. The connector lumen can be irradiated with ultraviolet light.

Also in this embodiment, the patient connector cap 2b is mounted on the second mounting table 5, and the bag connector cap 3b is mounted on the first mounting table 4, as in the above-described embodiments. Thereby, the moving mechanism becomes simple.

In this embodiment, a pair of ultraviolet irradiation lamps 1a and 1b are arranged between the patient connector 2 and the bag connector 3, which are arranged in parallel, with the irradiation lamp front ends facing each other. In this example, since a pair of ultraviolet irradiation lamps are separately provided on each mounting table, the patient connector 2 is displaced by displacing one or both of the mounting tables 4 and 5 as in the previous embodiment. Not only that, an ultraviolet irradiation lamp (1b) is inserted into the lumen of the bag-side connector 3 (FIG. 11), and both connector lumens 2a and 3a are almost simultaneously sterilized. Therefore, the patient connector 2 and the bag connector 3 do not need to be sterilized separately, and the working efficiency increases. Further, by sterilizing not only the patient connector but also the lumen of the bag connector connected thereto, contamination can be further prevented.

In this example, as in the above-described example, the relative movement of the two mounting tables is different from that of the mounting table parallel to the connector axis.
(Perpendicular to the connector axis). The movement of the former (in the horizontal direction shown in FIGS. 9, 11, 12, and 14) causes the patient connector and the bag connector to be attached to and detached from each cap, and the movement of the latter (in the vertical direction shown in FIGS. 10 and 13). ), The patient connector main body and the ultraviolet irradiation lamp or the bag connector main body face each other.
