ABSTRACT:
A guard assembly for a hypodermic needle comprising a hinge guard portion. The hinge is connected to the hypodermic needle at a location distal the pointed end of the needle. The guard portion is attached to the hinge such that the guard portion is movable relative to the needle. The guard portion has a receiving slot extending longitudinally therethrough for receiving the pointed end of a hypodermic needle. The receiving slot opens through the wall transverse to the longitudinal axis of the guard portion. The hinge is a flexible strip connected at one end to the needle and at the other end at the guard portion. The guard portion is a cylindrical member having a longitudinal V-cut narrowing from the wall of the cylindrical member to the receiving slot. An end cap is fixed to the end of the cylindrical member so as to cover the end of the longitudinal V-cut and receiving slot. The hinge may include a sheath portion with an inner area attached to the exterior of the hypodermic needle.
