Drug injector for muscle recovery

Abstract

The invention discloses a drug injector for muscle recovery. The drug injector comprises an injector pipe, a needle head is arranged at one end of the injector pipe, the end, away from the needle head, of the injection pipe is sleeved with a third circular ring, a piston pipe is arranged in the injection pipe, a rubber piston sleeve is arranged at the end, close to the needle head, of the piston pipe, the end, away from the rubber piston sleeve, of the piston pipe is sleeved with the third circular pipe, and a vent channel is formed in the side wall of the piston pipe. The drug injector is simple in structure, gas is compressed so that the rubber piston sleeve can expand and be tightly attached to the inner wall of the injection pipe, liquid in the injection pipe is prevented from leaking from a gap between the rubber piston sleeve and the injection pipe to avoid waste, the needle head can be taken down after injection is completed and put into a placing groove to be prevented from being damaged, a stop rod is inserted into the placing groove and is fixed by attractive force between two annular magnets, and the needle head is fixed under the action of spring force and prevented from waggling and then being damaged.

Description

technical field [0001] The invention relates to the technical field of syringes, in particular to a drug syringe for muscle recovery. Background technique [0002] Syringe is a common medical equipment, the emergence of syringe is an epoch-making revolution in the field of medical equipment, and the process of needle extraction or injection of gas or liquid is called injection. The syringe consists of a syringe with a small hole at the front end and a matching piston core rod, which is used to inject a small amount of liquid or inject it into areas that are inaccessible by other methods or withdraw it from those places. When the core rod is pulled out, the liquid Or the gas is inhaled from the small hole at the front end of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in; when the existing syringe is injected, it is easy to appear that the piston and the syringe are not tightly bonded, causing the liquid medicine to leak , causing waste. ...
