Vertical injection mechanism of needleless injector

Abstract

The vertical injection mechanism comprises a barrel, an injection push rod is arranged in the barrel, a medicine tube is arranged at the other end, away from the injection push rod, of the barrel, a fixing ring is arranged at the other end, away from the injection push rod, of the barrel, a center base is installed in the fixing ring, a rotating disc and a clamping spring are arranged on the center base, and the rotating disc is connected with one end of a traction rope; the other end of the traction rope is fixed to the center base, a plurality of equal-height columns are arranged at the lower end of the fixing ring, and a vertical observation window is further arranged in the fixing ring. The needle-free injector has the beneficial effects that the restriction that a conventional needle-free injector cannot perform vertical injection is overcome, the treatment effect in the injection process is guaranteed to the greatest extent, meanwhile, fear of an injected person in the injection process is eliminated, pain is reduced, comfort in the treatment and rehabilitation process is achieved, and the treatment effect is improved. And the pursuit of medical staff and patients on good treatment effect and wishes is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a vertical injection mechanism of a needle-free syringe. Background technique [0002] In addition to the wide application of needle-free syringes in basic medicine, clinical medicine, forensic medicine, laboratory medicine, preventive medicine, health care medicine, rehabilitation medicine and other fields, the needle-free syringe application industry also requires more convenient operability and more efficient practicability for medical workers and patients , The comfort is more superior, the research of needle-free injection technology is of great significance to the promotion of independent innovation in the field of medical engineering, technological progress and industry development, its importance lies not only in its economic benefits or economic role, but also in its social benefits. [0003] The conventional needle-free syringe mechanism includes an injection pu...

AI Technical Summary

Problems solved by technology

[0004] Conventional needle-free syringe mechanism, because its principle is to make the plastic silicone on the head of the injection push rod deliver the drug out of the nozzle of the drug tube through pressure, so as to complete the injection process. During the injection process, it is a needle-free injection. When the injection drug tube contacts In the human body, the injection angle cannot be controlled, which affects the dose of the injected drug into the subcutaneous tissue and affects the therapeutic effect
