  • Safety syringe system
    Patent number: 6716199
    Abstract: A system for converting an off-the-shelf syringe into a safety syringe for preventing accidental needle stick or infection. The preferred embodiment of the present invention is configured to mount to an off-the-shelf syringe via threaded, snap, permanent, or other engagement to the cannula hub of the syringe, wherein the device may include the needle for mounting to the syringe, or via barrel rings configured to mount about the barrel of the syringe. The device is configured to convert the syringe into a safety syringe including a protective cover in longitudinal communication with the syringe needle, the protective cover configured to longitudinally envelope the base of the needle in a storage position, and engage and cap the needle tip in a protected configuration after the instrument has been utilized.

  • Safety syringe system
    Patent number: 5312372
    Abstract: A safety system for use in conjunction with an instrument having a needle, wherein there is included a spring biased, locking pushbutton or activation tab apparatus which communicates with a locking safety sheath situated at the base of the hypodermic needle prior to activation. The safety sheath is in sliding, longitudinal communication about the needle, and is activated to its sheathing position by pressing a pushbutton or activation tab on the locking pushbutton or activation tab apparatus, directing the sheath from about the base of the needle to over the tip of the needle. Upon communication with the tip, the safety sheath deploys a locking hatch, preventing the urging of the sheath back to the base, and rendering the needle unreuseable.
