Abstract
A gun-type needleless injector comprises a gun body and a launching mechanism, and is characterized in that: the gun is characterized in that internal threads are arranged in the muzzle, an exhaust hole is arranged on the gun barrel, an electronic igniter (known technology) is arranged in the gun body, the bullet head of the bullet in the gun barrel is flat, smokeless powder and an electronic initiation device are arranged in the bullet, and the rear head of the bullet is provided with a positive electrode and a negative electrode. When in use, the liquid medicine is pumped into the ampoule, the ampoule is arranged on the internal thread in the muzzle, the ampoule injection hole is aligned to the part to be injected, the electronic igniter switch is pressed to complete one-time injection, and the gas generated by gunpowder is discharged from the exhaust hole. The invention has the beneficial effects that: because the electronic lighter is arranged in the gun body, the gun can be repeatedly used, thereby saving trouble and labor, and being safe and cheap.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically a kind of gun type needleless injector.
Background technology
At present, known syringe is a kind of medical apparatus and instruments commonly used, but its shortcoming is a syringe needle people's skin is had damage, particularly need the patient that everyday injects, the invention of needleless injector can be removed patient's misery, but present needleless injector kind is few, the price height is hung back a lot of patients.
Summary of the invention:
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of gun type needleless injector is provided.This gun type needleless injector simple structure, cheap, be easy to produce.
The present invention solves the technical scheme that its above-mentioned technical problem adopts: a kind of gun type needleless injector, it comprises rifle body and trigger mechanism, it is characterized in that: in muzzle, be provided with female thread, on gun barrel, be provided with steam vent, be provided with electronic lighter (known technology) in the rifle body, the bullet of the bullet in the gun barrel is flat, and bullet is built-in to be cordite and electronics priming device, and the bullet back is provided with both positive and negative polarity.During use medicinal liquid is extracted in the ampoule, ampoule is installed on the female thread in the muzzle again, the ampoule injection orifice is aimed at the position that needs injection, press the electronic lighter switch and just can finish a shot, the gas that gunpowder produces is discharged at steam vent.
The invention has the beneficial effects as follows: because of being provided with electronic lighter in the rifle body, can be repeatedly used, not only save trouble, laborsaving, but also safe, cheap.
Description of drawings
