  • SPRING LAUNCHED NEEDLE SAFETY CLIP
    Publication number: 20080249480
    Abstract: A hypodermic needle assembly configured such that the movement of a needle shield into position to block the needle tip occurs as a direct consequence of a longitudinal force applied by insertion of a syringe plunger is provided. The hypodermic needle assembly according to the present invention includes a needle, a needle hub, and a safety spring clip assembly, the safety spring clip assembly being configured to automatically launch from the needle hub and slide along the needle to shield the needle tip, thus preventing accidental contact with the needle tip. Additional mechanisms for launching the safety spring clip are also provided, which include using a trigger ring for rotating and launching the safety spring clip. Methods for making and using the hypodermic needle assemblies are also disclosed.
