Description

Medical syringe

Technical Field

Background

Syringes are common medical devices that primarily use needles to draw or inject gases or liquids, and syringes may also be used for medical devices, containers, and scientific instruments such as those used in chromatography to inject through rubber septa.

The principle of the syringe was proposed by katienel, italian as early as the 15 th century, but the first human trials were not conducted until 1657 in boile and rayne, the first fugren used a glass syringe. The glass has good transparency, so that the condition of injecting the medicine can be seen, the injector which is made of glass tube metal and is used for boiling sterilization, the needle head can be sharpened for reuse and sterilized, the existing injector is made of plastic and is thrown away once, so that the risk of infection during injection is greatly reduced, and in order to ensure sanitation and prevent cross infection, the modern injector is mostly made of plastic.

Syringes may also be used in medical devices, containers, scientific instruments such as those used in chromatography, where injection of gas into a blood vessel would cause air embolism, where removal of air from the syringe to avoid embolism is by inverting the syringe, tapping gently, and then squeezing out a little liquid before injection into the bloodstream, where accuracy is a primary concern rather than a pathogen, such as quantitative chemical analysis, is still in use due to the small error of the glass syringe and smooth plunger movement, or where the syringe is used to inject some juice into meat to improve taste and texture when cooking meat, or into pastries when baking.

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.
