AI Technical Summary

Problems solved by technology

The piston is a cone made of rubber. Due to the characteristics of rubber and its chemical materials, it has certain toxic and side effects, especially direct contact with the injection liquid, which is likely to cause adverse effects on human health.
More importantly, although the existing syringes are all nominally disposable, they often cannot be reused from the structure of the syringe itself, so it is easy to cause cross-infection of infectious diseases and bring great harm to human health.
In addition, the end of the push rod is flat against the outer surface of the hand. This structural design makes the operation feel unsatisfactory, which will bring inconvenience to the work of medical staff.

Abstract

An expendable self-destroy aseptic injector is composed of an external graduated sleeve tube and a tubular or cross bar-type push rod. It features that the front end of said push rod has a movable push plug matched with the liquid outlet of external sleeve tube, its front segment has one or more slots for embedding one or more sealing rings made of silica gel or PVC in them, and its back end has a concave surface for matching with finger end.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable self-destructing aseptic syringe. Background technique [0002] At present, the single-use syringes are all composed of a syringe jacket with a graduated line, a push rod and a piston connection. The piston is a cone made of rubber. Due to the characteristics of its chemical material, the rubber has certain toxic and side effects, especially direct contact with the injection liquid, which is likely to cause adverse effects on human health. More importantly, although the existing syringes are all nominally disposable, they often cannot be reused from the structure of the syringe itself, so it is easy to cause cross-infection of infectious diseases and bring great harm to human health. Furthermore, the end of the push rod is flat according to the outer surface of the hand, and this structural design makes the operation feel unsatisfactory, which will bring inconvenience to the work...
