Description

Labor-saving injector capable of assisting in injecting medicine

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a labor-saving injector capable of assisting in injecting medicines.

Background

A syringe is a common medical device that primarily uses a needle to draw or inject a gas or liquid. Typically, a 2 ml, 5 ml, 10 ml or 20 ml syringe is used, occasionally 50 ml or 100 ml, and a 1 ml syringe is used for intradermal injection. The syringe barrel may be plastic or glass and is typically provided with a graduated indicator of the volume of fluid in the syringe. Glass syringes can be sterilized with an autoclave, but because of the low cost of disposal of plastic syringes, most modern medical syringes are made of plastic, which further reduces the risk of blood-borne diseases.

At present, when skin lesions such as herpes zoster are injected, because a needle head is thin, although an injector is still relaxed when medicines are sucked, the injector is very laborious when medicines are injected, and the problem of injection labor is solved. If the injector which can inject the medicine in a labor-saving way can be provided, the injector can provide convenience for the medical staff to finish injection during special injection operation.
