Syringes are a common medical device. As early as the 15th century, the Italian Catinell proposed the principle of a syringe. Mainly used for injection of liquid medicine or liquid. Syringes can also be used to inject medical devices, containers, and scientific instruments, such as those used in some chromatographic methods, through rubber septa. Injecting gas into blood vessels will cause air embolism. The way to remove air from the syringe to avoid embolism is to invert the syringe, gently tap it, and then squeeze a little liquid before it is injected into the bloodstream.

The syringe consists of a syringe with a small hole in the front and a matching piston rod. The syringe is used to inject small amounts of liquid or other methods into the area near the syringe or to withdraw from those areas. Liquid or gas is sucked from the small hole at the front end of the syringe when the core rod is pulled out, and the liquid or gas is pushed out when the core rod is pushed in. The process of withdrawing or injecting a gas or liquid with a syringe and a needle is called an injection.

Syringe syringes can be made of plastic or glass, and are usually indicated on the scale above to indicate the volume of liquid in the syringe. Glass syringes can be sterilized with autoclaves, but because of the lower processing costs of plastic syringes, modern medical syringes are mostly made of plastic, which further reduces the risk of blood-borne diseases. The spread of disease, especially the spread of HIV and hepatitis, is related to the repeated use of needles and syringes among intravenous drug users.
