Problems solved by technology

[0002] Ordinary medical syringes can easily cause the spread of blood-borne diseases (such as hepatitis B, AIDS, etc.) among the crowd because they can be reused, causing serious social harm
In recent years, people have researched and developed many kinds of disposable syringes with destruction devices that can be automatically destroyed after use, but there are not many types of such disposable self-destructing syringes that can be practically used. Most disposable self-destructing syringes have complex structures and difficult assembly. There are defects in the design function, and the performance is not stable enough

Abstract

The invention relates to the field of medical injector, and discloses a disposable self-destruction injector. The disposable self-destruction injector comprises a needle cylinder, a push rod and a piston, wherein the piston is provided with a piston hole in which an inserter is inserted; the inserter is provided with an inserter upper part and an inserter lower part; the inserter lower part is inserted into the piston hole to seal the piston; the inserter upper part protrudes out of the piston hole; the inserter upper part is smaller than the diameter of the piston hole; and the lower part of the piston is provided with a containing layer which is arranged on the needle cylinder bottom or push rod. On the premise of not changing the application method and operation steps of the common medical injector, the drop of the inserter exposes the piston hole, thereby achieving the goals of disposable use and self-destruction of the injector. The invention is simple, convenient, practical, economical and the like.

Description

technical field [0001] The invention relates to the field of medical syringes, in particular to a disposable self-destructing syringe. Background technique [0002] Common medical syringes can easily cause the spread of blood-borne diseases (such as hepatitis B, AIDS, etc.) among the crowd because they can be reused, causing serious social harm. In recent years, people have researched and developed many kinds of disposable syringes with destruction devices that can be automatically destroyed after use, but there are not many types of such disposable self-destructing syringes that can be practically used. Most disposable self-destructing syringes have complex structures and difficult assembly. There are defects in the design function, and the performance is not stable enough. Contents of the invention [0003] The purpose of the present invention is to provide a disposable self-destructing syringe. The present invention achieves the purpose of disposable self-destructing b...
