Abstract
A guard for a hypodermic syringe needle which keeps the extremities and particularly the hands well away from the syringe to prevent accidental punctures with contaminated needles. The needle guard is in the form of a cylindrical cap which slides over the needle having a manipulating device to remove and replace the guard while keeping the hands well away from the needle. In one embodiment the manipulating device is in the form of a flexible handle for removing the cap. As an alternative the end of the needle guard can be flared to provide a flat surface for receiving an adhesive. The needle is then removed by pressing the adhesive base to any convenient surface. The needle guard is replaced by simply inserting the needle in the guard and snapping the guard from the surface by giving the syringe a quick twist when the cap is fully seated over the needle.
