Description
Technical field
This utility model belongs to injector for medical purpose technical field, especially relates to the improvement of a kind of needleless vaccine injection rifle structure.
Background technology
Needleless injection is a kind of in the new method that just can not carry out drug injection by syringe needle, because liquid medicine is directly entered body tissue, except medicine itself, other foreign bodies are not had to enter body, solving the drawback of above conventional injection, liquid medicine enters the gap Dispersed precipitate of tissue tailing edge tissue fibers, and the process that enters is to tissue injury and little, drug distribution disperse simultaneously, is beneficial to absorption.
At present, needleless injector is only applied on injection of insulin, outward appearance is the form of a stroke or a combination of strokes, and in vaccine injection scope, there is no suitable needleless injector occurs, vaccine injection object mostly is child, and have pin injection not only can increase the fear of child, and add pain, it is easy to hemorrhage, there is wound in skin surface, and drug residue rate is relatively larger.
Utility model content
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of needleless vaccine injection rifle.
A kind of needleless vaccine injection rifle of the present utility model, including injection gun body, sleeve, sleeve back-moving spring, rifle bolt, rifle bolt draw-in groove, brute spring, gunslinging part, rifle bolt brake lever, trigger, rifle bolt brake unit, medicinal liquid bullet, one end, top of injection gun body is provided with sleeve, and one end of sleeve is connected to sleeve back-moving spring, and be connected by sleeve back-moving spring is fixing with the fixing nut of one end of injection gun body, rifle bolt it is provided with in sleeve, and the medial wall of sleeve is provided with rifle bolt draw-in groove, rifle bolt is fixedly mounted on rifle bolt draw-in groove, rifle bolt is made up of brute spring and gunslinging part, one end of gunslinging part is fixing with brute spring to be connected, gunslinging part is connected by rifle bolt brake lever and trigger are fixing, one end of gunslinging part is arranged below rifle bolt brake unit, one end of gunslinging part is connected with medicinal liquid bullet.
As preferably, the lateral surface of described sleeve is provided with non-skid band, has certain skidproof effect.
The beneficial effects of the utility model: its reasonable in design, simple to operate, easy to use, by adopting Needleless injection, it is possible not only to make patient without fear and pain, and can reuse, have only to change syringe, environmentally-friendly sanitary, failure rate is low, greatly reduce consumptive material expense, improve work efficiency.
