Abstract
Abstract An apparatus for neutralizing and disposing of infectious solid waste and non-hazardous solid waste includes a housing having an upper chamber for receiving the infectious solid waste and a lower chamber for receiving the non-hazardous solid waste. The upper chamber includes an exterior loading door, and an interior discharge door. A discharge ram forms one wall of the upper chamber opposite to the discharge door. The upper chamber includes door seals and pressure fittings so that the infectious waste placed therein may be sterilized by steam introduced under pressure. The neutralized wastes are ejected by the discharge ram through the interior door into the lower chamber. One wall of the lower chamber comprises a compactor ram which is extendable through a discharge opening to compress the neutralized and non-hazardous wastes into a closed compactor container.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
166 words
Apparatus for receiving, treating, and disposing of bio-hazardous or infectious solid wastes and non-hazardous or non-infectious solid wastes, comprising a housing defining a pair of discrete separate adjacent chambers, the first of said chambers being enclosed and having an opening therein through which infectious waste may be introduced, said first chamber being adapted to permit steaming and sterilization of the infectious waste, the second of said chambers being enclosed and having an opening therein through which non-infectious material may be introduced, means defining a passage interconnecting said first and second chambers, a closure for selectively opening and closing said passage, means for ejecting the sterilized contents from said first chamber into said second chamber through said passage when said closure is in an open position, and compaction means in said second chamber for selectively compacting the non-infectious waste and for compacting the infectious waste received from said first chamber and for ejecting all of such waste from said housing at one end of said second chamber.
Claim 2
Dependent Claim
166 words
Apparatus for receiving, treating, and disposing of bio-hazardous or infectious solid wastes and non-hazardous or non-infectious solid wastes, comprising a housing defining a pair of discrete separate adjacent chambers, the first of said chambers being enclosed and having an opening therein through which infectious waste may be introduced, said first chamber being adapted to permit steaming and sterilization of the infectious waste, the second of said chambers being enclosed and having an opening therein through which non-infectious material may be introduced, means defining a passage interconnecting said first and second chambers, a closure for selectively opening and closing said passage, means for ejecting the sterilized contents from said first chamber into said second chamber through said passage when said closure is in an open position, and compaction means in said second chamber for selectively compacting the non-infectious waste and for compacting the infectious waste received from said first chamber and for ejecting all of such waste from said housing at one end of said second chamber.
Claim 3
Dependent Claim
42 words
Apparatus as set forth in claim 1 in which said compaction means comprises a ram extending across said second chamber, said second chamber end has a discharge opening, and said ram is translatable towards said discharge opening and away from the same.
Claim 4
Dependent Claim
47 words
Apparatus as set forth in claim 1 in which said first chamber overlies said second chamber and said passage permits gravital deposit of said sterilized waste from said first chamber to said second chamber, and said ejection means includes a ram translatable towards and from said passage.
Claim 5
Dependent Claim
19 words
Apparatus as set forth in claim 3 in which said passage overlies said second chamber adjacent said discharge opening.
