Injection syringe |
摘要 |
A hypodermic injection system with a retractable needle wherein the needle retracts within the interior cavity of a syringe plunger, so that the needle is safely and confinedly held within the plunger for ease of handling and transport, while remaining safely therein. A cylindrical spring housing has resilient fingers which can capture a coiled spring which biasly holds a needle holder against the retaining force of the resilient fingers. The plunger has a frangible end, which, when engaging the resilient fingers under a pre-determined amount of force, dissociate while remaining inwardly-tapered shoulders spread the resilient fingers, allowing the coiled spring to eject the needle and its holder into the interior cavity of the syringe plunger. |
