Abstract
Abstract A hand carried, hand operated portable device for destroying hypodermic cannulas and syringe barrels, Luer and slip tips of plastic syringe barrels is disclosed. The device comprises a portable housing enclosing a needle chamber for the safe storage of sheared cannula pieces. Mounted on the housing is a means for shearing cannulas, (20 to 30 guage) whereupon the sheared cannula falls into the storage compartment. Once a sheared cannula has entered the storage compartment, it cannot be conveniently removed unless the device is destroyed. Optionally mounted on the housing is a means for shearing the plastic barrel, Luer and slip tip of a hypodermic syringe, to prevent its misuse after its intended use. The device of the invention is highly portable, hand operated and disposable following a plurality of uses.
