ABSTRACT:
A compact medical waste disposal device, operable without water or other processing, disposal or disinfecting fluid or solution, for pulverizing Sharps into medically acceptably safe small particles, and directing the particles into a disposable container. The disposal device comprises a waste receiving and pulverizing chamber containing a pulverizing disc blade, with the disc blade being operable only when the pulverizing chamber is sealed. The pulverizing disc grinds the medical waste against the inner surface of a closely adjacent liner of the pulverizing chamber. Relatively heavy elements, rotatably swing on the upper surface of the pulverizing disc to direct medical waste materials and fragments, towards the pulverizing interface between disc and liner. Comminuted medical waste, falls beneath the blade into a disposal chamber, where a sweeper element, integral with the underside of the disc blade and rotatable therewith, continuously completely clears pulverized material, without fluid disposal carriers, into an outlet attached to a disposable container. The disc blade embodies at least one short recessed portion of the circumference thereof, preferably in the form of a flat, offset from the liner by up to 1/8", to permit resilient medical waste (rubber, plastic and similar materials) to pass therethrough without blade jamming.
