Description

Anti-acupuncture syringe

Technical Field

The utility model relates to a hospital nursing articles for use technical field, especially a prevent acupuncture syringe.

Background

The injector is an epoch-making revolution in the field of medical appliances, and consists of a syringe with a small hole at the front end and a matched piston core rod, and is used for injecting liquid into an area which cannot be accessed by other methods or extracting the liquid from the area, sucking the liquid or gas from the small hole at the front end of the syringe when the core rod is extracted and extruding the liquid or gas when the core rod is pushed in.

Syringes may also be used for injection through rubber septa in medical devices, containers, scientific instruments such as in some chromatography. Injecting gas into a blood vessel will cause air embolism. The removal of air from the syringe to avoid embolism is accomplished by inverting the syringe, tapping gently, and then squeezing a little liquid before re-injecting it into the bloodstream.

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. The transmission of diseases, particularly HIV and hepatitis, among drug addicts who inject drugs intravenously is associated with the reuse of needles and syringes.

In clinic, when medical staff use an injector to fill a liquid bottle with a medicament, the exposed sharp needle head is easy to stab the medical staff.
