At its proximal end, it is provided with a dosing attachment. The dosing attachment is preferably a spray attachment. In another embodiment, the cylinder open at one end serves to receive commercially available disinfection vials.

Description

Mobile device for antimicrobial door opening

description

The mobile antimicrobial door opening device of the present invention serves to effectively reduce microbiological transmission pathways of surfaces such as e.g. from door handles to palms.

State of the art

In public buildings, such as clinics and hospitals but also in toilets or other high-traffic public spaces, such as children's nursery, commercial kitchens, administrative buildings, airports or railway stations, it can be assumed that a not insignificant number of different pathogens on the Door openers are located. Disinfection of the hands is not always done. Especially in toilet facilities or clinics and

Hospitals is this transmission path of so-called

Smear infections are crucial for the transmission of numerous

pathogenic germs. Occasionally there are containers with a disinfectant in hospitals next to the doors

Hand disinfection.

In addition to the possibility of individual hand disinfection before and after entering a room a number of measures are presented in the prior art, which should remedy this problem.

Thus, in DE 202009012556 U discloses a device for the hygienic use of door opening means which a receiving box for a

Foil sheet stack or disinfection wipes and a disposal part comprises. The device is designed so that the uppermost sheet of foil by hanging up the user's hand and moving it

Foil sheet is removable. The receiving box is above the

Door opener attached.

[0005] DE 202009013271 U1 discloses an antibacterial coating on grip elements. This covering can be firmly connected to the door opener or formed as a coating.

In DE 10014472 A1, in turn, a self-disinfecting door opener is presented, which contains a reservoir for disinfectant and a pump mechanism. By depressing the door opener, a lever presses on the pump mechanism, so that the

Disinfectants via openings in the handle area, e.g. is distributed on a sponge rubber.

The document KR 1020090084051 A discloses a device for disinfecting the hands, which is attached to the door handle and has a receptacle for a disinfecting bottle.

US 20100294806 A1 and US 20060153733 A1 disclose solid

Disinfecting devices on the door. In US 20100294806 A1 the door handle itself is equipped so that the disinfectant can be removed from the door handle in a dispenser. In

US 20060153733 A1 discloses a device which is mounted above the door opener and sprayed by pressure on the door opener with disinfectant.

All of these prior art devices have in common that high investments are required for the retrofitting of all doors in the corresponding facilities with disinfection devices. In addition, have antibacteriostatic coatings or

Coatings only have a temporary effect, so they need to be renewed at regular intervals.

A mobile device for opening doors is in

US 20070046050 A1. A short handle is with a hook connected, which can fold out of the handle by a mechanism like a car key by pressing a button.

Presentation of the invention

[001 1] The invention is therefore based on the object to develop a device for antimicrobial door opening, which is easy to handle with high efficiency and cost-effective production.

The problem is solved by the inventive features in the

Claims.

The mobile device according to the invention is provided with a curved,

hook-like part connected at its distal end. An inside hollow, adapted to the palms grip part in the form of a one-sided open cylinder is designed with a dosing attachment at its proximal end for receiving disinfectant. The dosing attachment is preferably a spray attachment.

In another embodiment, the one-sided opened

Cylinder as a receptacle for commercial disinfectant bottles.

Before the bent part, a closed end of the handle portion is arranged as a support surface for a finger or a thumb.

The device consists of a disinfectant-resistant plastic, a metal or a metal alloy. The bent part is covered with silicone or consists of a non-slip material.

It is advantageous if over the handle part and the lower end of the

bent part a handle cover is arranged. The handle cover can be adapted to the shape of the palm.

Advantages of the invention are an individual hand disinfection in

Needed. The use of much more expensive hygiene products or Self-opening doors, antibacterial-coated surfaces or door handles equipped with UV light are unnecessary.

Embodiment of the invention

The invention will be explained in more detail with reference to drawings. 1 shows the device according to the invention with dosing attachment,

FIG. 2 is an exploded view of FIG. 1;

3 shows a first embodiment with disinfectant vial, Figure 4 is an exploded view of Figure 3 and

Figure 5 shows another embodiment with integrally formed bent part.

The device for antimicrobial door opening is shown in FIG. It consists of a handle part adapted to the palm part 1. In the embodiment, this is a hollow, advantageously unilaterally open cylinder. At the distal end facing away from the opening, a bent part 2, similar to a hook, is arranged. The curved part 2 is about 10 cm long and the bow has a diameter of about 5 cm, so that any door opener can be conveniently included. The device can also be carried out in other dimensions, but offers by its form the smallest possible contact surface and thus the lowest possible attack surface for germs. The curved part 2 is covered with silicone or made of a non-slip material to prevent slipping from the door opener. For use, the device is placed over the door opener, which can then be depressed with the device. Likewise handles of swing doors can be enclosed and opened.

An advantageous embodiment is that in front of the curved part by the closed end of the handle part, a support surface 4 is formed for the fingers or the thumb. This will handle facilitated in that the leverage of the device is further supported and slipping can be avoided.

The handle part 1 consists of a disinfectant-resistant plastic or a metal / a metal alloy. Inside the

Handle part 1 is a chamber 5 for receiving

Disinfectant (Figure 2). The handle part 1 is connected at its proximal end with a metering attachment 3, advantageously with a spray attachment. The dosing attachment 3 can be screwed or plugged. A seal to protect against unwanted leakage of the disinfectant is provided in any case.

In the figures 3 and 4 is alternatively shown that the handle part 1 as a receptacle for commercial disinfectant bottles 6 with

Can serve spray attachment. For this purpose, the existing dosing attachment 3 is removed and the disinfectant vial 6 is inserted into the chamber 5 of the handle part 1. The attachment can be done by clamping effect or a corresponding, not shown here union nut. Another useful embodiment is to provide a handle cover 7 on the handle part 1 and the welded or glued bent part 2 here. The handle cover 7 may be adapted to the shape of the palm, for example, for right and left handers.

In Figure 4, the device of the invention as a

Exploded view of Figure 3 shown. Here, in addition to the disinfectant bottle 6, the handle part 1 and the bent part 2 together with the handle cover 7 and the silicone sheath 8 for the bent part 2 can be seen.

Figure 5 shows a further possibility of how the bent part 2 can be attached to the handle part 1. For this purpose, the bent part 2 is formed in the area adjacent to the handle portion 1 9 in order to achieve a slim connection between the handle part 1 and 2 bent part. Of course it is also possible, the curved part 2 directly with the support surface 4, be it by welding or screws to connect.

By this device, it is possible that the wearer can not only open doors without touching them directly by hand, but he also has at any time a disinfectant at hand. As a result, this device is of particular interest for nursing professions.
