Abstract
Abstract A needle guard for use with a hypodermic syringe comprising a substantially cylindrical hollow body, having a first end that is open and a second end that is closed, wherein said guard has attached to an external surface thereof and projecting therefrom a grasping tab adapted so that the user can hold the body of the needle guard by grasping the tab, thus removing the user's hand from the projected line of force described by the insertion of the needle into the needle guard. The improved needle guard reduces the incidence of accidental puncture wounds which users of hypodermic syringes often experience.
