Description

Disposable syringe destroyer

Technical Field

The invention belongs to the technical field of syringe destroying devices, and particularly relates to a disposable syringe destroying device.

Background

In order to prevent the used disposable syringes from being used repeatedly to cause cross infection, the national health administration department requires that each medical unit destroys the used disposable syringes on the spot, so as to meet the requirements of 'separation of the needle and the barrel, and destruction of the needle and the barrel'. To achieve this, a number of syringe destroyers have been developed.

At present, people generally adopt a mode of bending a needle of the syringe, such as a syringe destroyer (publication No. CN202539168U) disclosed in chinese patent literature, in which destruction is realized by bending the needle at 90 °. However, the needle is also easily bent back after being bent, and is easily repaired, so that the syringe may be reused, and the syringe cannot be destroyed completely.

Disclosure of Invention

The purpose of the invention is: aims to provide a disposable syringe destroyer which is used for solving the problems that the existing destroyer has structural defects that only a needle head can be destroyed, a needle cylinder cannot be destroyed, and the destruction efficiency is low.

In order to achieve the technical purpose, the technical scheme adopted by the invention is as follows:
