A protector for self-retractile hypodermic needles, the purpose of which is to hide and protect the needle used in injections, both before and after its use. Its basic features are a tubular body (1) opened on both ends and cylindrical, at least inside, including an inner ring-shaped projection (3) with minimum width and thickness, which holds the needle-holder (6). The body includes as well an expansion spring (5) placed between the end projection of the needle-holder provided to be held against the inner projection of the tubular body, and the strangled front end of the latter. The spring pushes the needle-holder in, hiding the needle (7), once the syringe has been used for an injection. The tubular body is provided with elongated side windows (4) to simultaneously hold both the tubular body and the syringe during use. <IMAGE> |
