Abstract: A system for disposing of large amounts of infectious hospital waste includes a generally sealed enclosure containing an apparatus for delivery, disintegration, and decontamination of waste materials. A dual conveyor arrangement provides a positive delivery of large waste containers to be disposed to a disintegrator while preventing material from being thrown from the disintegrator. The disintegrator comprises two, large, counter-rotating hammermills capable of effectively disintegrating articles of substantial size. The system enclosure is maintained at a negative pressure and adapted to prevent escape of airborne contamination from the system. A variety of protective features is also incorporated into the system to clear the disintegrator in cases of overload, to avoid power surges upon system start-up, and to effect an orderly shutdown of the system.

Abstract: A system is provided having a generally sealed cabinet and separator. A blower is provided in the sealed cabinet to provide a negative pressure within the cabinet. A waste entrance is provided in the cabinet which provides a sealed, rotatable input for the introduction of hospital waste to the system. In the system, the input rotates upon operation of a switch to direct solid waste to a disintegrator, such as a hammermill, wiht a flow of disinfectant fluid. Upon disintegration, the waste particles and disinfectant fluid are carried to the separator which is sealed with the cabinet. The solid waste is separated from the decontaminant fluid which is then directed to a public sewer.

Abstract: A tray is provided with a display area and housing area, the display area having an array of grooves for reception of hypodermic syringes, and pockets for reception of oral medications. Medication card slots are provided adjacent the grooves and pockets. A vertical wall is provided facing the needle end of syringes to prevent them from accidentally falling off the edge of the tray, and to prevent accidental brushing against the needles by the tray user or passerby. The housing portion includes a used cotton and swab receiver pocket, and a door-covered syringe receiver chamber having a sloped bottom and manually operable, when desired, to dump used syringes into a suitable final disposal container without again handling them. The tray may be made of a single piece of formable or moldable material such as plastic or metal, for example, and the door may be made of plastic or metal to best suit the circumstances.
