Abstract
A hypodermic needle removal and disposal device (10) for removing hypodermic needle assemblies (62) from hypodermic syringes (60) comprises an elongated storage container (12) which can be held in one hand having at a top end thereof a needle removing shield (24). The needle removing shield includes an apron (26) for extending laterally outwardly beyond an outer surface (14) of the elongated storage container and a funnel-shaped top surface (30) slanting toward a cone shaped needle-removal plateau (28). The needle-removal plateau forms an elongated hole (44) through a plateau surface (46) thereof having a size that is only slightly larger than hubs (66) of hypodermic needle assemblies. Hypodermic syringes can be maneuvered so that needle assemblies mounted thereon extend into the elongated hole and the hypodermic syringe can then be rotated laterally about the hub of the hypodermic needle assembly. The hub is held stationary by the elongated hole and cannot follow this rotation, thus, threads which engage the hypodermic syringe with the hypodermic needle assembly are separated. The needle assembly falls into the elongated storage container.
