Abstract: A single-use hypodermic syringe having a syringe barrel with distal and proximal ends. The syringe barrel includes a flange at the proximal end thereof and a luer locking collar at the distal end thereof. A needle assembly is removably coupled to the distal end of the syringe barrel. The needle assembly includes a hub and a needle extending from a distal end of the hub. A plunger is telescopically positionable within the barrel. A tubular shield is disposed around the syringe barrel such that the syringe barrel can be moved relative thereto. The shield includes locking prongs extending proximally therefrom, and a spring for moving the syringe barrel from an unused position, where the shield allows exposure of the needle assembly, into a used position where the shield covers the needle assembly.
