Syringe is a common medical instrument. As early as the 15th century, the Italian Cartinel put forward the principle of the syringe. Gas or liquid is extracted or injected mainly with a needle.
Syringes can also be used to inject medical devices, containers, and some scientific instruments in chromatography through a rubber diaphragm.
Use of disposable syringe
Syringes can also be used to inject medical devices, containers, and some scientific instruments in chromatography through a rubber diaphragm. Injecting gas into the blood vessels can cause an air embolism. The way to remove air from the syringe to avoid embolism is to turn the syringe upside down, tap it gently, and then squeeze out a little liquid before injecting it into the bloodstream.
In some cases where precision is not the primary concern of germs, such as quantitative chemical analysis, glass syringes are still used because of their small error and smooth push rod movement.
You can also use syringes to inject juices into meat during cooking to improve flavor and texture, or into pastries during baking. A syringe can also fill the cartridge with ink.
Specifications of disposable syringe
Generally, 2 ml, 5 ml, 10 ml or 20 ml syringes are used, occasionally 50 ml or 100 ml syringes are used for intradermal injection.
Syringes can be made of plastic or glass and usually have a scale indicating the volume of liquid in the syringe. Glass syringes can be sterilized with autoclaves, but because plastic syringes are cheaper to dispose of, modern medical syringes are mostly made of plastic, which further reduces the risk of blood-borne diseases. Reuse of needles and syringes is associated with the spread of diseases, particularly HIV and hepatitis, among intravenous drug users.
