Description

Medical atomizing injector capable of increasing recognition degree

Technical Field

The utility model relates to the technical field of injectors, in particular to a medical atomizing injector for increasing recognition degree.

Background

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 method of removing air from the syringe to avoid embolism is to invert the syringe, tap it gently, and then squeeze out a little liquid before injecting 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.
