Abstract
Apparatus for providing passive protection against accidental needle-stick for a hypodermic needle extending from a hub. There is a tip protector comprising a cross-piece disposed transverse to the needle having an elongated first bore therethrough through which the needle passes and having a bell-shaped tip-guard extending from the cross-piece concentrically about the first bore and covering a tip portion of the needle with the tip protector in an extended position. The tip protector is slidably moveable along the needle supported by the elongated first bore between the extended position and a retracted position with the tip portion of the needle exposed for use. Guide apparatus guides the tip protector between the extended position and the retracted position. A coil spring biases the tip protector to the extended position. A releasable lock automatically and releasably locks the tip protector in the extended position when the tip protector moves to the extended position from a position retracted therefrom. The tip protector can ride on guide rails extending from hub parallel to the needle of on support rails extending from the cross-piece into guide tubes extending from hub parallel to the needle by away from it.
