Abstract: The invention discloses a syringe construction which permits use of standard hypodermic needles and allows the hypodermic needle to be retracted into the body of the syringe after use to minimize accidental pricking from the needle by withdrawing the needle into the syringe body such that it is not exposed. The invention provides for a syringe body having an engaging thread on the distal end for receiving a hypodermic needle, adjacent to the engaging thread is a positioning groove and locking surfaces for engaging a needle carrier, a needle carrier is removably engaged to the body which has a distal end which will mate with the needle and a proximal end providing an engaging means for engaging the syringe plunger. The plunger has a engaging means for engaging the needle carrier such that the needle carrier can be rotated and retracted into the syringe body.
