A syringe is a common medical device. As early as the 15th century, the Italian Catinelle proposed the principle of the syringe. The gas or liquid is withdrawn or injected mainly with a needle.
Classification of models and specifications:
(1) Generally use 2ml, 5ml, 10ml or 20ml syringes, occasionally use 50ml or 100ml, and use 1ml syringes for intradermal injection.
(2) Syringe barrels can be made of plastic or glass, and glass syringes can be sterilized with an autoclave. However, because plastic syringes are less expensive to dispose of, most modern medical syringes are made of plastic. (This also further reduces the risk of blood-borne diseases, the spread of which among intravenous drug users, especially HIV and hepatitis, is associated with the reuse of needles and syringes)
