The syringe can be made of plastic or glass. The glass syringe can be sterilized with an autoclave. In 1956, New Zealand doctor Colin Murdoch invented a disposable plastic syringe, which not only upholds the advantages of traditional glass syringes that are transparent and inert, but also has the characteristics of not being easily damaged, easy to transport, low in cost, easy to recycle, etc. Unmatched by glass syringes, it greatly reduces the risk of blood-borne diseases. Since then, large-scale production of new syringes has begun, and have gradually become the first choice of doctors'.
