Abstract
Hypodermic syringes with accompanying hypodermic syringe needles may readily utilize the disclosed safety device to achieve less operator risk of needle stick injury and less risk of body fluid contamination. In the preferred embodiment the safety device, which can be releasably affixed to the barrel of a hypodermic syringe having an attached hypodermic syringe needle, has a channel-like member that houses a forwardly movable, generally L-shaped member and a rocker spring. After injecting substances into or withdrawing body fluids from a human being or an animal, the L-shaped member is pushed forwardly somewhat beyond the tip of the hypodermic syringe needle. The downwardly action of the rocker spring cooperating with the design features of the L-shaped member causes the L-shaped member to move downwardly past the tip of the hypodermic syringe needle and then rearwardly so that the tip of the hypodermic syringe needle becomes embedded into the L-shaped member.
