Abstract

The invention discloses a disposable all-plastic self-destruction syringe comprising a needle cylinder and a push rod, wherein the push rod is movably arranged in the needle cylinder. The disposable all-plastic self-destruction syringe is characterized in that the head of the push rod is provided with a sealed piston head, the sealed piston head comprises a piston body, the outer ring of the piston body is provided with two piston rings, and an M-shape cavity is formed between the piston ring and the piston body. The entry of the needle cylinder is provided with a needle cylinder holder, the needle cylinder holder and the tail of the needle cylinder form a card containing cavity, the tail of the push rod is provided with two or a plurality of cards, and the head of the card is in tapered shape. The invention can prevent leakage from happening between the push rod and the needle cylinder, and the push rod can not be pulled out after injection, so that the invention can thoroughly avoidthe phenomenon of secondary use and ensures safe pharmacy.

Description

technical field [0001] The invention relates to a disposable syringe, in particular to a disposable all-plastic self-destructing syringe. Background technique [0002] Existing disposable all-plastic syringes realize their tightness through rubber pistons and silicone oils, and rubber pistons and silicone oils are poisonous and harmful, threatening human health. [0003] If the existing disposable all-plastic syringes are not destroyed in time after use, they may be reused, resulting in the mutual transmission of various viruses and cross-infection among personnel. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a disposable all-plastic self-destruct syringe, which can prevent leakage between the push rod and the syringe. [0005] In order to solve the above-mentioned technical problems, the technical solution of the disposable all-plastic self-destructing syringe of the present invention is: [0006] It includ...
