A hypodermic, preferably a disposable hypodermic syringe has provision for rendering the needle (12) incapable of harming anyone when the syringe has been used or is discarded. The syringe operates with an initially retracted needle (12) which is driven to a protruding position when the syringe is used. After use, the needle (12) is retracted from the protruding position and bent into a safe position by rotation of a disc (6) about a post (18). |
