ABSTRACT:
A syringe is molded with an integral needle cover or guard that pivots about a main living hinge on the side of the syringe near the base of the needle. A tension spring formed from an L shaped integrally molded part of the syringe and guard extends from a location closer to the syringe than the main living hinge to the center part of the pivoting guard. The user, while holding the syringe with one hand, can extend a finger to initiate rotation of the guard toward the needle. This extends the tension spring at first, but beyond a certain angle, the tension spring contracts again, pulling the guard the rest of the way into a position surrounding the needle.
