Abstract

Abstract A closure is provided comprised of a thin flexible material for use on a needle disposal container so that a contaminated blood collection needle may be removed from its holder and deposited in the container without the user touching the needle or the needle hub. The device includes an elongated tapered opening to accommodate varying diameters of needle hubs. A feature of the invention includes a plurality of spaced apart elongated slots extending from each side of the opening which enhances the flexibility of the edges of the opening, which, in turn increases the wedging or wrench-grip action for unscrewing a needle from a collection assembly and at the same time allows ready transfer to a disposal container. The cap of the invention is configured to be utilized with a large variety of collection containers of varying sizes and shapes.
