ABSTRACT:
A protective cover for a hypodermic needle employs a pair of guide rods for guiding a protective cap from a retracted position to an extended protective position for shielding the hypodermic needle. A guide member projects transversely from the needle base and forms a pair of apertures which receive and interact with the guide rods. The guide rods are fixed to a protective cap portion of the cover. A guide rod mechanism is also employed in connection with a retractable, foldable sheath embodiment. The protective cover assembly may also take the form of telescopic shield sections which lock in the extended protective position by means of a cooperative projection/groove locking engagement.
