PROBLEM TO BE SOLVED: To safely and easily store a medical needle and to inexpensively execute sanitary abandonment with a simple structure by covering a needle tube to its tip when a cylindrical body is moved forward, permitting a needle base part to have a part with a diameter being larger than that of an inner cavity in the cylindrical body in a free state and extending/contracting the inner cavity by means of the movement of the large diameter part in the cylindrical body. SOLUTION: When injection is completed, the wings 9 are grasped by one hand, the needle is pulled-out and an injected part is pressurized by sterilizing cotton by the other hand to stop bleeding. Then two wings surfaces are put together in the opposite direction of a notch forming side to open the notch 6 of the cylindrical body 5, the notch 6 is largely opened, the inner cavity of the cylindrical body is extended so that a duct 4 is pulled by on hand while grasping the wings 9 by the other hand. Then the needle tube 2 is pulled in to the cylindrical body 5 and stored. The large diameter part 8 of the needle base end part is moved to the base end side end point 10 of the notch 6 and, then, the inner cavity of the cylindrical body is hardly extended to stop it. The needle tube 2 is perfectly stored inside the body 5 to the tip of it at that position so that an injection needle 1 with the wings are abandoned without worrying about erroneous piercing. |
