Disposable, reusable safety syringe for human or animal use. When in use, the needle protective sleeve is cut along the parallel direction of the needle, the protective sleeve is pulled away from the needle for injection, and the protective sleeve is reset after the injection, so that the needle no longer hurts people, so as to achieve the purpose of one-time prevention of repeated use. The protective cover has a limited position for the blade of the special attachment, which can easily cut the protective cover under any circumstances [1]. $ The combination of protective cover and needle can be used with other types of syringes without storage bag.
How it works
Safety syringes add protection to medical staff on the basis of self-destructing syringes. The structure is as follows: on the basis of self-destruction, the needle is retracted and the sheath and the sheath are moved forward to protect the needle, thereby realizing safe injection.
