The appearance of the syringe is an epoch-making revolution in the field of medical appliances. The process of using a needle to extract or inject gas or liquid is called injection. Medela Medical Syringe is composed of a syringe with a small hole at the front end and a matching piston core rod, which is used to inject a small amount of liquid or inject it into areas that cannot be accessed by other methods or withdraw it from those places, and then pull out the core rod. When the liquid or gas is inhaled from the small hole at the front end of the syringe, the liquid or gas is squeezed out when the mandrel is pushed in.
Syringes can also be used in medical devices, containers, and scientific instruments such as some in chromatography to inject through rubber septa. Injecting gas into a blood vessel will cause an air embolism. The way to remove air from the syringe to avoid embolism is to turn the syringe upside down, tap it lightly, and squeeze out a little bit of fluid before injecting into the bloodstream.
In some occasions where precision rather than germs is a concern, such as quantitative chemical analysis, glass syringes are still used due to the small error of the glass syringe and the smooth movement of the push rod.
You can also inject some of the juices into meat with a syringe to improve taste and texture while cooking, or into pastries when baking. Syringes can also fill ink cartridges with ink. Generally use 2 ml, 5 ml, 10 ml or 20 ml syringe, occasionally use 50 ml or 100 ml, and use 1 ml syringe for intradermal injection.
Syringe barrels can be either plastic or glass, and usually have a graduated indication of the volume of liquid in the syringe. Glass syringes can be sterilized with an autoclave, but because plastic syringes are less expensive to dispose of, most modern medical syringes are made of plastic, which further reduces the risk of blood-borne diseases. The transmission of disease, especially HIV and hepatitis, among intravenous drug users is associated with needle and syringe reuse.
