Abstract
The utility model relates to a safety protective sleeve of an injector injection needle. The safety protective sleeve comprises a protective sleeve body and a needle base. The protective sleeve body is provided with a cavity used for containing the injection needle and a needle head. A syringe connecting device is arranged above the needle base, and a needle head connecting device is arranged below the needle base. The protective sleeve body and the needle base are arranged in a connected mode. A turnover fold line connected in an integrated mode is arranged on the lower portions of the protective sleeve body and the needle base. A side-by-side state fixing buckling device and a bottom butt joint state locking device are arranged between the protective sleeve body and the needle base. In the use process, a syringe is connected above the needle base. The needle head is connected below the needle base. After injection, the protective sleeve body is turned over so that the protective sleeve can rotate around the turnover fold line by 180 degrees, at the moment, the injection needle and the needle head are placed in the cavity of the protective sleeve, and therefore the purpose that an injection needle point is prevented from hurting and infecting medical staff and other personnel is achieved. The safety protective sleeve has the advantages of being simple in structure, low in manufacturing cost, convenient to operate and the like.
