ABSTRACT:
A hypodermic syringe and needle combination with a releasable, automatic needle enclosing sheath. A syringe barrel having an open and a closed end includes first and second longitudinally extending guide channels for guiding push rods secured to the thumb platform of a plunger rod. Ball-end engaging sockets are located at the ends of the guide channels for capturing ball-ends secured to the needle sheath which is slidably supported and displaceable between (1) a first position where the needle sheath is locked by engagement of the ball-ends in the sockets and which exposes the needle, and (2) a second position where the needle sheath encases the needle. The needle sheath is spring biased so that it travels from the first position to the second position when the ball-ends are released from the sockets by pressure applied on the thumb platform which causes the pushrods to push the ball-ends out of the sockets.
