To solve the problem that many tons of disposable syringes cannot be recycled, the structure of syringes has been redesigned. The syringe is provided with an inner box, the syringe tube and the liquid bottle are designed as a unit that can be placed in the inner box of the syringe to ensure the drug quality and stability of the syringe. Only the used needles and medicine bottles need to be replaced, and the syringes can be used again and again. This design is very suitable for use in remote areas and material shortage areas. This design will help more people to receive vaccines and protect their and the public's well-being.
