べた如くの安全注射器。[Scope of Claim for Utility Model Registration] (1) A cylindrical drug container with an open end and a neck with a reduced diameter; a pinching device is provided in the neck; the pinching device has an elastic pinching portion; The pincer has an inward pinching tendency, and has a needle support part for attaching the injection needle, the needle support part is tightly gripped by the pincer part, and the injection needle extends outside the drug container to perform the injection. It is located in a storage position. There is a spring, which exerts elasticity on the needle support and tends to move the needle support in the axial direction, and a small part is inserted into the open end of the container and joined with the container wall by a push-fit method. a hollow piston having a distal end surface and a hollow body, the distal end surface having an opening in communication with the hollow body, and the opening being obstructed by a temporary closure component, the hollow piston having a medicament When pushed toward the neck of the container, the closure part comes into contact with the needle support and breaks first, and almost at the same time is pushed by the tip end face of the hollow piston and the pinch part expands outward. , whereby the pinching part releases the pinching action of the needle support part and also pushes the needle support part into the hollow body of the hollow piston by the elasticity of the spring. (2) The utility model registration claim (1) is characterized in that the hollow piston has a stopper, and if the hollow piston is not held down to the position where it contacts the needle support part, its return movement is restricted. Safety syringe as mentioned. (3) Safety as stated in claim (2) of the utility model registration, characterized in that the stopper is composed of mutually mating wedge-shaped limiting protrusion rings provided on the inner wall of the container and the outer wall of the hollow piston, respectively. Syringe. (4) A fitting protrusion is provided on the contact surface of the pincer part with the needle support part, and there is a recessed groove on the needle support part to fit it, so that when the pincer part tightly pinches the needle support part, the fitting protrusion is provided. Utility model registration claim (1) characterized in that the fitting protrusion is fitted into the groove.
Safety syringe as described in ). (5) According to claim (1) for registration of a utility model, the needle support part has at least one protrusion extending downward, which destroys the blocking part when it comes into contact with the blocking part. Safety syringe as mentioned. (6) A safety syringe as described in claim (1) for utility model registration, characterized in that a pinching device is integrally connected to a drug container.
