Description

 Device for disinfecting skin and hands

The invention relates to a device for disinfecting the skin and hands, which attack a handle, in particular a door handle, wherein for placement on the handle, a shell is provided, in which a disinfectant is, which exits through openings in the shell. State of the art

Most of the germs we carry around are on the hands. We touch everything with our hands, shopping carts, doorbells, our face and we cough and sneeze into our hands. Not to mention the various hands being shaken. We carry the germs everywhere. We transfer them to other objects or even to humans. Especially in hospitals this becomes a danger, where freshly operated patients lie with an open wound and exactly there these germs can fix. That's why it's so important that we disinfect our hands so as not to endanger a patient.

Even when going out, it is advisable to disinfect his hands, as even dangerous germs inside the hospital are waiting to be taken outside. If especially emphasis is placed on sterility, first of all the hands have to be taken care of. Unfortunately, in hospitals and other facilities, the prescribed disinfecting of the hands is not always used for convenience. The device in DE 20 2004 006 845 U1 prevents this. The principle is that the door handle is surrounded by a plastic sheath and delivers disinfectant solution in use. Thus, it is impossible to enter or leave a room without disinfecting the hands. Here, a disinfectant solution is attached to a door, above the door handle. It is attached to a metal bracket, which is bolted to the door.

For the disinfectant solution commercially available solution should be used. This solution then runs in a plastic pipe of 1.5 mm diameter in the direction of the door handle or a shell around the doorknob. If the fingers exert pressure on the shell or channel walls, the plastic is pressed in, whereby flaps open and thus the disinfectant solution flows out.

The disadvantage of the above-mentioned invention is that extra a device for it must be screwed to the door. This is time consuming and not feasible when considering how many doors would need to be provided in a hospital, for example.

task

It is an object of the present invention to provide a device for disinfecting the skin, which overcomes the disadvantage mentioned above, which is easy to assemble and to handle. Solution of the task

To achieve this object, that the device for disinfecting the skin, comprising a shell with openings and at least one receiving element for receiving disinfectant, is set up so that disinfectant from the receiving element through the openings of the shell emerges when a pressure on the Shell is exercised.

Preferably, the disinfectant or the disinfecting liquid or the disinfecting solution is in a removable from the shell receiving element.

The receiving element is located in a shell that can be easily and easily placed at their destination, such as a doorknob or a door handle, the disinfectant escapes from openings in this case and reaches the skin of a person. This may be the skin of the hands, or other skin areas. The shell and the exception element contained therein have the great advantage that they are easy to install and change, in which case neither bored in a door, nor screwed must be.

It should be emphasized that not only door handles come into consideration as a handle, but by the present invention all conceivable handles be included. For example, carrying handles for carrying patients or injured persons, handles for furniture or even on the car or in airplanes are also included. It should be comprised of all elements that are attacked by hands and in which there is a desire that the hands be disinfected.

Furthermore, sheaths according to the present invention can be used in numerous other locations, surfaces, devices or articles which usually come into contact with human skin. It can be thought of switch of any kind, for example, to the operation button a toilet flush. Furthermore, it may be intended to other surfaces, such as door knob, means for holding, armrests, railings, or the like. The aforementioned surfaces or devices or objects are usually only in contact with the skin of the human hands or forearms. However, the present invention also encompasses devices that come into contact with the skin of other human body parts, such as toilet seat rings, seats and seat backs of chairs and benches, and the like.

All the aforementioned surfaces or devices, such as railings, doorknob, armrests, toilet seat rings, etc., are not only touched by the human skin, but the corresponding human body part also exerts a certain pressure on the surface or device. This pressure causes the release of the disinfectant from the shell to the skin.

The receiving element may be a cloth or sponge cloth, a fleece, a textile, a fabric or another absorbent or absorbable piece of material. This is particularly easy to place in the case and makes easy handling and replacement possible. The receiving element However, it may also be a reservoir or container which can be filled with disinfectant and which releases the disinfectant through corresponding openings during compression / compression. The sheath is preferably made of silicone, preferably of biosilicone, since silicone has the property of being very flexible and, above all, very long-lasting. In addition, the recycling idea also plays an important role in all things today and silicone is easily recyclable. Case for a door handle:

The cloth preferably has a thickness of 6-8 mm or thicker, whereby it is able to absorb a great deal of disinfecting liquid. This is associated with more frequent use and fewer replacements.

The amount of disinfecting liquid should also preferably be about 30 ml or more in the present invention. This is the optimum amount to be able to use the cover with the receiving element for about two to three days, depending on the traffic also daily, before the receiving element is replaced.

The shell in which the cloth is located and which is to be fastened via the door handle, is preferably made flexible. Thus, it can adapt to many types and shapes of door handles and can easily dispense the disinfecting fluid through appropriate openings.

The shell has edge trim and an end wall towards the end so that it can close and close the door handle well and no liquid can escape elsewhere except from the openings in the shell.

Inside the shell longitudinally extending support webs are attached, on the one hand hold the cloth in position and on the other hand, too much derive liquid so that only a small but sufficient amount of disinfectant can pass through the openings to a person's hand. The advantage here is that no disinfectant is wasted because too much may be dispensed through the openings.

The shell may be formed so that it consists of two shells, which can be connected to one another by an openable closure, in particular a plug-in closure. Thus, an easy installation on a door handle and also a non-slipping of the cloth is guaranteed inside.

The closure consists for example of mushroom-shaped nubs on a shell, which engage in the closed position in corresponding undercut openings in the other shell. The closure ensures that the shell sits firmly and securely on the door handle and can not be accidentally removed.

It should be noted that the openings in the shell, through which the disinfectant can escape, preferably have a diameter of about 1 mm. This is the optimal size to deliver enough fluid to a person's hand.

The shell itself has a length of about 95 mm, an outer diameter of 38/39 mm and a wall thickness of 2.5-3.0 mm. This makes it universal and can be used for every task. Case for a toilet seat ring, a railing, an armrest or the like:

Cases for toilet seat rings, railings, armrests, sheaths, disinfectant pads, toilet bowl operating buttons or the like function in the same manner as described above for the cases adapted to door handles. The main difference is the shape and the connection to the place of installation. For example, a rectangular disinfection pad becomes simple glued or screwed at the desired location and is available.

Cases for toilet seat rings or buttons for toilet flushing or railing or the like, similar to the shell for the door handle, be shaped so that they can be subsequently attached to the desired location (seat ring, control button, railing, etc.). Such attachment can be positive, cohesive or material, so for example by gluing, screwing, clamping, hooking, snapping or the like. Furthermore, it may alternatively be thought to replace existing seat rings, control buttons or the like by those which are already equipped with a shell according to the present invention.

Whether retrospectively or replacing an existing device, the present invention can therefore be used, for example, in the following locations: handrails such as railing handrails, toilet seat rings, door handles, other handrails, handrails, control buttons, Toilettenspül-control buttons, toilet brush handles, railings, any surfaces.

The door handle 1 will not be described further below.

The device V has a shell 2 which is provided with a plurality of small openings 3. The openings 3 in the preferred embodiment have a diameter of about 1 mm. The sheath 2 should preferably be made of silicone in order to ensure a high elasticity or flexibility and also stability. The thickness of the silicone shell 2 should be about 2 mm. In longitudinal section according to FIG. 2, the casing 2 and the openings 3 are clearly shown. Within the shell 2, a receiving element 4, for example, a cloth or sponge cloth, inserted. The receiving element 4 has a thickness of 6-8 mm and can accommodate a liquid amount of about 30 ml.

Furthermore, a recess 5 can be seen, which serves to enclose the door handle 1 at this point. In addition to the recess opening 5 edge strips 6.1 and 6.2 and opposite a closed or also open end wall 7 can be seen, which enclose the door handle 1 and thus completely seal the shell 2 and the interior 8 of the shell 2 in the use position, so that no liquid can escape.

In the interior 8 continue to run longitudinally extending support webs 9.1 and 9.2, which are according to Figure 3, the cross section of the present invention, in the interior 8 of the shell 2 between receiving element 4 and shell 2. They serve, on the one hand, to absorb too much of the liquid and, on the other hand, to hold the cloth or receiving element 4 in the interior 8. Furthermore, it is clear that the sheath 2 consists of at least two shells 10.1 and 10.2, which can be connected to one another by an openable closure 11, in the preferred exemplary embodiment a plug-in closure. The closure 11 is made in the preferred embodiment

mushroom-shaped nubs 12, which engage in the closed position in corresponding undercut openings 13 in the other shell 10.2.

In a further embodiment of a closure 11.1 according to FIG. 4, a groove 15 is integrally formed on the casing at one end, into which a latch 16 integrally formed in the closed position engages.

Overall, it should be mentioned that the preferred embodiment of the shell 2 has a length of 95 mm and an outer diameter of 35 mm.

The operation of the embodiment of the present invention shown in Figures 1 to 4 is as follows: We carry most of the germs on our hands, since we touch everything, shake hands, etc. However, especially in hospitals, to prevent the germs Anyone who touches a handle must disinfect their hands. But not everyone does. The sheath 2 of the present invention serves to change this by being fixed around a handle 1.

Inside the envelope 2 there is a receiving element 4, for example a cloth or sponge cloth. This is squeezed when attacking the door handle 1 and immediately directs disinfectant liquid through the openings 3 in the shell 2 to the outside and thus wets the hand of the person who has grasped the door handle 1. Now the person only has to rub both hands together and both hands are disinfected, whereby For example, fewer germs can be taken in and out of hospitals.

The present invention can be used for any handle 1, and no extra structures are needed. In addition, the receiving element 4 in the interior 8 of the shell 2 is easily replaceable.

Figure 5 shows a device V for use as a seat or seat ring 16 of a toilet. The device V shown in Figure 5 can either be used in place of a known seat ring, or be applied to a known seat ring. The seat ring 16 is preferably made of silicone and comprises a shell 2 with openings 3, of which only a few are indicated in FIG. Furthermore, the seat ring comprises filling openings 17 for the disinfectant. Inside the seat ring 16 are one or more receiving elements 4 (not shown), for example in the form of wipes.

The operation of the device V shown in Figure 5 in the form of a seat ring 16 is the following: The seat ring 16 is analogous to the door handle according to Figures 1 to 4. Exercises a user pressure on the seat ring 16 by, for example, sits on it, so occurs Disinfectant from the openings 3. To disinfect the seat ring 16 before sitting on it, you can wipe it with toilet paper or the like. By a pressure exerted during wiping of the seat ring 16 pressure, disinfectant passes through the openings 3 and can be distributed using the toilet paper on the seat ring 16.

The receiving element 4 or the like in the interior of the seat ring 16 can be exchanged on the one hand after consumption of the disinfectant. For this purpose, the seat ring 16 comprise shells, as described above for the attachable to door handles 1 Case 2. On the other hand, it can alternatively be thought of the receiving element in the interior of the seat ring (in Figure 5 not shown) via the filling openings 17 to refill and regenerate, so to speak, after the disinfectant has been consumed.

Figure 6 shows a device V for use as operating buttons 18 of a known toilet flush. The device V shown in Figure 6 can either be used in place of known control buttons, or be placed on known control buttons. Of course, the principle shown in Figure 6 can be transferred to other controls for toilet flushing with one or more than two control buttons. The control buttons 18 are preferably made of silicone and each comprise a shell 2 with openings 3, of which only a few are indicated in FIG.

The operation of the device V shown in FIG. 6 in the form of control buttons 18 is as follows: If a user presses one of the control buttons 18, he exerts a certain pressure on this control button 18. As a result, the receiving element (not shown) inside the casing 2 emits disinfectants via the openings 3 to the hand of the user. The functional principle has already been described with regard to the exemplary embodiments according to FIGS. 1 to 5.

FIG. 7 shows a device V in the form of a disinfection pad 19 comprising a sleeve 2 with openings 3, of which only a few are indicated in FIG.

The disinfection pad 19 according to FIG. 7 functions in the same way as the devices V according to FIGS. 1 to 6. The functional pad can be installed in a suitable place and allows the users to disinfect those skin parts with which a pressure is exerted on the disinfection pad 19 becomes. FIG. 8 shows a device V, which differs from the device V shown in FIG. 2 only with respect to a cover 20 and with regard to the filling openings 17. The mode of operation of the device V shown in FIG. 8 is substantially the same as in accordance with FIG. 2 and has the following differences: Disinfectants can be introduced via the filling openings 17 in order to regenerate the receiving element 4. The lid

20 can be removed to replace the receiving element 4 as needed.

FIG. 9 shows a device V similar to that according to FIG. 3. The device according to FIG. 9 has a reservoir 21

The mode of operation of the device V shown in FIG. 9 essentially corresponds to the function of the devices V according to FIGS. 1 to 8. The reservoir 21 serves to receive the disinfectant, while the sponge 4 (represented by dashed lines) via an inner shell 22 from the reservoir 21 is separated and located between the inner shell 22 and the shell 2. The inner shell and the shell 2 each have (not visible in Figure 9) openings to deliver the disinfectant upon application of force / compression of the shell 2 by a hand from the reservoir via the sponge cloth 4 to the hand. Because the reservoir

21 and not the cloth 4 is used to receive and store the disinfectant, the cloth 4 can be made very thin in the embodiment of Figure 9. FIG. 10 shows a device V, which differs from the device shown in FIG. 9 only in that there is no sponge cloth 4 and no inner casing 22. The openings in the shell 2 are not visible for clarity. The disinfectant is in the reservoir 21. If the shell 2 and thus also the reservoir compressed / compressed, so disinfectant occurs through the openings to the outside and wets, for example, the hand which compresses the shell 2. There are numerous modifications of the above-described embodiments conceivable. Thus, the sheath 2 can be hinged in all embodiments of the present invention. For this purpose, the shell 2 have a folding mechanism and a closing mechanism, so that the shell 2 on the one hand unfolds easily and on the other hand is held securely in the operating position at the destination. The unfolding can serve to change the receiving element 4.

The envelope 2 can be held with a suitable closure on a door handle or other destination. It is also conceivable that the shell 2 is placed on a door handle, wherein the shell 2 can be made in one or more parts, in particular in two parts. On the other hand, it is conceivable to design a door handle so that it already provides a part of the shell. Such a door handle can be, for example, half-shell-shaped and semicircular in cross-section. The shell 2 forms the complementary half-shell and is placed on the door handle to complete this. Inside, a reservoir 21 and / or a sponge cloth 4 or the like can be located.

With regard to the embodiments of the inventive device V, which are attachable to a door handle 1, at least two basic mechanisms for opening the shell 2 are conceivable.

On the one hand can be thought of a folding mechanism as described above. A part of the shell 2 can in this case be firmly connected to the door handle 1, while another part is designed hinged. The parts may be, for example, the trays 10. On the other hand, the shell 2 may be configured in two parts. A part of the shell 2 is in this case permanently mounted on the door handle 1. The other part is replaced each time the disinfectant is used up. Both of these parts result in combination enclosing the door handle 1 2.

As an alternative or complementary to the unfolding mechanisms described above, all embodiments of the present invention may be equipped with filling openings 17. This may be thought to provide a closure or the like for a bottle for refilling, which is designed so complementary to the filling openings 17, that filling with other commercially available disinfectant bottles is not possible. As a result, abuse and incorrect operation, such as filling the wrong disinfectant avoided. Instead of the bottle for refilling, only its cap or filling tip or filling / filling pin can be designed to be complementary to the filling openings 17 as described above.

Instead of the cloth or sponge cloth may also be a tile, another textile or fabric or any for the (usually water or alcohol-based) disinfectant absorptive or absorbent substantially sheet-like piece of material to be considered. The cloth or sponge or textile, fabric, piece of material or the like can serve in all embodiments for one or more of the following purposes: receiving and storing and dispensing of the disinfectant; Passing or passing the disinfectant coming from the reservoir 21; Barrier against bacteria, viruses and / or germs (bacterial / viral / and / or germ filters) entering the shell 2 from outside, dirt particles or the like.

The shell 2 can be designed to be foldable in all embodiments of the present invention. After unfolding, the cloth, Piece of material or the like when it is consumed, contaminated with bacteria or dirt, or simply replaced after a certain interval. The number and arrangement of the filling openings 17 can be adapted to the circumstances of the individual case or place of use.

It may be thought of as any suitable closures as alternatives to the closure 11.

All measures mentioned with reference to the figures or elsewhere in the description of the present invention are exemplary and not restrictive. It may also be intended for devices of other dimensions. This concerns, for example, the measures concerning the diameter of the openings 3, the thickness of the silicone shell 2, the thickness of the cloth, the length of the shell and its outer diameter and their

Wall thickness and the amount of liquid.
