[0002] The pre-filled syringe is a new type of medicine and equipment integrated packaging system combining medicine storage and injection function, originated in the 1990s, mainly used for precise drug delivery of vaccines, biological agents and high value medicines, and its core components include a tube sleeve made of glass or polymer material, a rubber piston, a push rod and a stainless steel injection needle. Through the pre-filling process, the drug and the packaging are directly compatible, reducing the pollution risk and liquid absorption loss in the transfer process. Compared with the traditional ampoule and syringe separation drug delivery method, this technology significantly improves the dose accuracy, operation safety and clinical efficiency, and is especially suitable for biochemical drugs that need to be stored for a long time. In recent years, with the progress of material technology, plastic pre-filled syringes have gradually solved the problems of glass material fragility and specification limitations, further expanding the application scenarios in veterinary medicine and large dose drug delivery fields, and becoming an important innovation direction in the pharmaceutical packaging field.
