The Englishman Ferguson was the first to use a glass syringe. The transparency of the glass is good, and you can see the situation of the injection of everything. Afterwards, there is a syringe made of glass tube metal and used, which can be sterilized by boiling method. The needle can also be sharpened and reused and sterilized. The syringes used today are made of plastic and thrown away once, greatly reducing the risk of infection during injection. In order to ensure hygiene and prevent cross-infection, contemporary injection responders mostly use plastic texture.
