Disclosed is an improved safety injector equipped with needle winding-and-storing means (4,24). It comprises a cylindrical container (6,26) and a needle winding axle (5,25) rotatably fixed therein. The hub (2) of a needle-and-hub body is fixed to the syringe (1) to draw or purge liquid therefrom, and to the bottom of the winding axle (5,25) at an eccentric position relative to the center axis of the cylindrical container (6,26) to permit the needle (3) of the needle-and-hub body to pass therethrough. After using the injector the cylindrical container (6,26) is made to turn about the winding axle (5,25), thereby pulling in and winding the used needle of the needle-and-hub body around the winding axle (5,25). <IMAGE> <IMAGE> |
