Background

As early as the 15 th century, kathler, italian, proposed the principle of the syringe. The first human trials were not performed until 1657 in the british boyle and rayne. Abel, a surgeon in the French Queen Louis sixteen (in 1774 and 1792) military, has also conceived a piston syringe. Prasutz in france is generally considered the inventor of the syringe. He manufactured the syringe in 1853, which was made of silver and had a volume of only 1 ml and a threaded plunger rod.

The first Fragren of England used a glass syringe. The glass has good transparency, and the condition of the injected medicine can be seen. The syringe made of glass tube metal can be used for sterilization by boiling, and the needle can be used for sharpening and sterilization. The existing syringe is made of plastic and is thrown away once, so that the risk of infection during injection is greatly reduced. In order to ensure hygiene and prevent cross-infection, modern syringes are often made of plastic.

Syringes are a common medical device. As early as the 15 th century, kathler, italian, proposed the principle of the syringe. Gas or liquid is primarily drawn or injected with a needle.
