Description

Door handle for preventing cross infection

Technical Field

The invention belongs to the field of medical supplies, and particularly relates to a door handle for preventing cross infection.

Background

Bacterial viruses often cause serious transmitted diseases, and especially in places with large accumulation of pathogens and high population density such as hospitals, the necessity of pathogen control is more important.

In the hospital department, in order to satisfy the patient's cold-proof condition and play better isolation, can set up multichannel insulated door usually, when daily use, the cross infection is realized through the door handle very easily to the germ, because insulated door quantity is more and the frequency of use of door handle is high, the cleaner is difficult to accomplish the effective cleanness many times a day, in addition, because the disinfectant volatility of configuration is strong, after spraying on the handle, the disinfection effect of its performance is very limited, and the duration is shorter, thereby leaves the opportunity for the propagation of germ.

To this end, we propose a door handle for preventing cross-infection to solve the above problems.

Disclosure of Invention

The invention aims to provide a door handle capable of timely sterilizing a handle and preventing cross infection, aiming at the problems of high cleaning difficulty and poor effect of the conventional door handle.

In order to achieve the purpose, the invention adopts the following technical scheme: a door handle for preventing cross infection, comprising a handle body and an upper connecting piece and a lower connecting piece, wherein the inside of the handle body is provided with:

the mixing cavity is arranged in the middle of the handle body;

the mixing mechanism comprises a mixing pipe which is fixedly arranged in a mixing cavity and is provided with an opening at the upper end and the lower end, the two ends of the mixing pipe are hermetically and slidably connected with piston blocks, the part of the piston block, which is positioned at the outer side of the mixing pipe, is hermetically and slidably connected with the mixing cavity, the piston blocks and the mixing cavity form a closed temporary storage cavity, the two piston blocks and the mixing pipe form a closed extrusion cavity, the temporary storage cavity is communicated with the extrusion cavity through a one-way input pipe, and two sides of the extrusion cavity are provided with one-way jet holes;

the storage cavities are arranged in the handle body, the two storage cavities are communicated with the two temporary storage cavities in a one-to-one correspondence mode, and the storage cavities are communicated with the temporary storage cavities through one-way discharge pipes;

two arc diving boards, arc diving board is made by netted elastic material, two the arc diving board sets up both sides around the handle body respectively, be equipped with the fluting that corresponds with arc diving board on the lateral wall of hybrid chamber, the both ends of arc diving board respectively with two piston piece fixed connection, work as arc diving board is close to when taking place deformation towards the handle body, can drive two piston pieces and remove towards the direction of keeping away from each other.

In the above door handle for preventing cross-infection, the connector is hollow inside and communicates with the storage chamber, and the connector is provided with a supplementary mouth.

In the door handle for preventing cross infection, the lower part of the arc-shaped elastic plate is coated with a water-absorbing non-woven fabric material, and the L-shaped spray pipe corresponding to the arc-shaped elastic plate is fixedly communicated with the one-way spray hole.

Compared with the prior art, the door handle for preventing cross infection has the advantages that:

1. according to the invention, by arranging the mixing mechanism and the arc-shaped elastic plate, when a pedestrian holds the door handle to open the door, the arc-shaped elastic plate is deformed and drives the piston block to move, so that water and disinfectant are sucked into the extrusion cavity to be mixed, and when the pedestrian leaves, the arc-shaped elastic plate recovers deformation and drives the piston block to move, so that the extrusion cavity ejects the mixed disinfectant water to disinfect the arc-shaped elastic plate and the handle.

2. The invention can be used for preparing the disinfectant at present by arranging the two separated storage cavities, and avoids the condition of invalidity caused by long-term placement of the disinfectant, thereby greatly improving the disinfection effect of the disinfectant.

3. According to the invention, the supplementary nozzle is arranged on the connecting piece, so that disinfectant and water can be conveniently added into the mixing cavity, the smoothness of the outer part of the handle body can be ensured, and the handle is convenient for a user to hold.

4. In addition, when the water column of the disinfectant is sprayed on the net-shaped part of the arc-shaped elastic plate, the net-shaped structure can further play a role in cutting the water column, so that the disinfectant can be divided into smaller water drops, the diffusion range of the disinfectant is further improved, and the disinfection effect is improved.
