JPS607428Y2 - Cap for preventing back contamination - Google Patents

Description

[Detailed description of the invention] This invention is based on sterile water, that is, water in an aseptic or sterile state (
This is a cap that prevents back contamination of sterile water that is attached to a faucet or shower that supplies sterile water (hereinafter referred to as sterile water), and is related to a cap that prevents back contamination of sterile water at the outlet of sterile water from a faucet or shower used for hand washing in surgical procedures in hospitals, etc. The purpose is to prevent

Generally, when sterile water is supplied to a faucet or shower at the point of use through a supply pipe, when the sterile water is not in use, the sterile water outlet of the faucet or shower is in contact with the atmosphere, so bacteria adhere to the outlet of the sterile water, resulting in so-called back contamination.

In addition, faucets and showers used for washing hands during surgery are used less frequently and for a shorter total time, so they remain unused for a long time, leading to significant back contamination and adverse effects such as hospital-acquired infections.

Conventional heating methods and ultraviolet irradiation methods are available to improve this drawback, but in the case of the former heating method, sterile water is constantly heated by electric heat, so when using it, not only is it dangerous because boiling water comes out at first, but also There are disadvantages such as the consumption of money.

Furthermore, in the case of the latter ultraviolet irradiation method, continuous irradiation heats the ultraviolet germicidal lamp, which shortens its lifespan and reduces its bactericidal power.

The present invention compensates for and eliminates the above-mentioned drawbacks in the simplest way, by placing a cap on the sterile water outlet of a faucet or shower that communicates with the sterile water supply pipe and covering the outlet with a sealed seal. This is a cap for preventing reverse contamination, which is detachably attached as shown in FIG. By attaching the cap to the faucet or shower, back contamination of sterile water is prevented.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory view when the cap 3 of the present invention is attached to the sterile water outlet portion of the shower 2 which communicates with the sterile water supply pipe 1.

At this time, sterile water is not used, and the sterilizer is sterilized by the action of a valve mechanism 5 such as a ball valve attached to the cap 3 from a sterilizer container 4 installed on a wall higher than the shower 2. The drug is injected into the cap 3 through the drug injection tube 6.

The amount of sterilizing agent to be injected is adjusted by a float valve 8 in the sterilizing agent injection amount adjusting mechanism 7 which is made of a material such as polyethylene resin which has a specific gravity smaller than the specific gravity of the sterilizing agent.

That is, by injecting sterile water to a position 10 higher than the outlet portion 9 of the shower 2, the float valve 8 closes the outlet of the cap 3, and the amount of sterilizing agent to be injected can be saved.

In addition, when using sterile water, after removing the cap 3 of the present invention, hang it from the sterile water supply pipe 1 with something like a chain 11 to prevent it from coming into direct contact with other substances such as the floor. can do.

At this time, the disinfectant in the cap 3 flows out.

Fig. 2 is an explanatory diagram of an embodiment in which the sterilizer container 4 is installed on the floor lower than the shower 2, and at this time, as in Fig. 1, sterile water is not used, and the sterilizer is applied manually. Alternatively, the sterilizer is injected into the cap 3 through the sterilizer injection tube 6 by the action of a foot pump (not shown) and the valve mechanism 5, and the amount of sterilizer to be injected is adjusted in the same manner as in FIG.

As described above, by attaching the cap of the present invention to the sterile water outlet of faucets and showers, the sterilizing agent injected into the cap prevents back contamination of the sterile water outlet when sterile water is not in use. It has a very hygienic effect because it can prevent it.

In the case of a cap without a valve mechanism, the cap is immersed in a container containing a sterilizing agent and then attached to a faucet or shower that supplies sterile water.
