Abstract
A needle guard for a syringe having a forward annular member with an internal diameter sufficient to extend around a diameter of a syringe needle, a cap flexibly fastened to the forward annular member, a rearward annular member having a diameter suitable for attachment to the syringe, and a resilient member connected to the rearward annular member and connected to the forward annular member so as to urge the forward annular member away from the rearward annular member. The cap is fastened to an end of the forward annular member opposite said resilient member. The cap is movable from a first position in proximity to an end of the forward annular member and a second position away from the end of the forward annular member. A drawstring is connected at one end to the forward annular member and extends toward the rearward annular member so as to actuate a movement of the forward annular member toward the rearward annular member.
