Tail fastening type vaccine injector

Abstract

The invention relates to the technical field of medical instrument, concretely to a tail clip vaccine syringe, in particular to a self-destructing mechanism of the tail clip vaccine syringe. According to the technical proposal provided by the invention, the tail clip vaccine syringe comprises an outer casing, a movable first core bar which is arranged in the outer casing and a second core bar which is connected with the tail part of the first core bar. The lower part of the second core bar extends to the outside of the outer casing. The self-destructing mechanism is characterized in that a head part of the first core bar is provided with a piston; the self-destructing mechanism is arranged between the tail inner wall of the outer casing and the tail external wall of the first core bar; the self-destructing mechanism prevents the first core bar from retracting to the tail part of the outer casing after the first core rod drives the piston to move to the head part position of the outer casing. The syringe can realize the automatic assembly line production. Therefore, the tail clip vaccine syringe can be used very simply and easily.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tail clip type vaccine injector, and in particular to its self-destruction mechanism. Background technique [0002] At present, there are many types of self-destructing vaccine syringes, but one thing is the same, but there is a need to change the usage habits to some extent, and they cannot be operated with one hand. Defects such as easy misoperation bring great inconvenience to medical staff when injecting vaccines. Contents of the invention [0003] The purpose of the present invention is to provide a new tail card type vaccine syringe, which can realize automatic assembly line production. So the implementation of this tail card type vaccine syringe is very simple and easy. [0004] According to the technical solution provided by the present invention, the tail clip type vaccine syringe includes an outer casing, a movable first core rod located in the outer casin...
