Abstract

A high-safety injector is composed of tube body, holding part, metallic needle and injecting rod. Its operation method is also disclosed. Its advantages are simple structure, easy assembling and automatic withdraw of needle.

Description

technical field [0001] The invention relates to a safety syringe, in particular to a safety syringe whose needle can be retracted automatically. Background technique [0002] In the process of medical treatment, drug injection is a common medical behavior, but medical staff are often accidentally punctured by injection needles, resulting in infection, so they must be very careful when handling needles to prevent medical staff or waste disposal personnel from Getting pricked by a dirty needle. [0003] China Taiwan No. M249673 patent discloses a retractable safety syringe with a retractable hook, which includes a syringe, a needle and an injection rod. The pull hook assembly of the push rod body is composed of a pull hook at the front end of the cork. The pull hook is made use of the negative pressure formed in the process of drawing the injection liquid and the pulling force applied to the injection rod through the structure of the check tenon. The assembly and the push ro...
