Novel push-out self-destructive injector

Abstract

The invention discloses a novel push-out self-destructive injector. A needle seat mounting column is arranged at the upper end of an injector barrel body, a needle seat is installed in the needle seat mounting column, a needle tube is arranged at the center of the needle seat, a baffle ring is disposed at the upper end of the needle seat, the upper end of the needle seat mounting column is inwards contracted to form a clamping ring which is matched with the baffle ring, the lower end of the needle seat is tightly sleeved with a seal ring which is tightly attached to the inner wall of the needle seat mounting column, a piston mounting portion is installed at the upper end of a push rod in the barrel body, an ejecting rod is formed in the middle of the piston mounting portion, the ejecting rod enables the needle seat to overcome resistance of the clamping ring on the baffle ring and then ejects the needle seat out of the needle seat mounting column when upwards pushed to a certain position, a piston is sleeved on the piston mounting portion, and a deforming cavity is arranged between the middle of the piston and the outer wall of the ejecting rod. According to the novel push-out self-destructive injector, the liquid medicine residues are minimal, which are close to 1 / 3 of national standards, environmental protection during subsequent recycling or destruction of the injector is facilitated, the self-destruction is complete, the operation is simple and convenient, and the novel push-out self-destructive injector is suitable for being used by medical workers.

Description

technical field [0001] The invention belongs to the technical field of disposable syringes, in particular to a novel ejector self-destructing syringe. Background technique [0002] With the progress and development of society, people's requirements for medical treatment are getting higher and higher, and medical devices are also constantly innovating and improving, especially the improvement in syringes has been greatly improved. At present, disposable plastic syringes have been widely used. Ordinary disposable syringes are discarded after one use, which can prevent virus infection caused by the reuse of the syringes, which is safer and hygienic. However, the disposable syringes currently on the market are troublesome to use due to their complicated structural design, and they cannot be completely self-destructed, and their production costs are relatively high, which is not conducive to popularization. Contents of the invention [0003] The purpose of the present inventi...
