Abstract
A bio-hazardous waste compactor is described which provides a negative air pressure and venting system while allowing for the filtration of the air and control of sound. The compactor contains a sealed chamber which includes a sump area in the bottom of the chamber for fluid control. Waste is weighed so that the operator knows when to remove the waste. Ultraviolet light is provided to prevent the growth of vegetative pathogenic organisms. Finally, a disposable bag to be used in connection with such a bio-hazardous waste compactor is described which has an inner porous layer, an intermediate, biocide-containing, super-absorbent polymer layer and an outer non-porous layer.
Claims22
A bio-hazardous waste compactor comprising:
- a sealable compartment having an opening;
- open-ended receptacle means for receiving bio-hazardous waste;
- reciprocal support means mounted within said sealable compartment for detachably supporting and reciprocally moving said open-ended receptacle means into and out of said sealable compartment through said opening;
- a compaction boot movable into and out of said open-ended receptacle means;
- reciprocating means extending into said sealable compartment for reciprocally moving said compaction boot into and out of said open-ended receptacle means;
- cover means for covering said opening when said open-ended receptacle means is moved into said sealable compartment;
- first sealing means disposed between said sealable compartment and said cover means for providing an airtight seal;
- second sealing means provided where said reciprocating means extends into said sealable compartment, said second sealing means further ensuring said airtight seal;
- and
- means in fluid communication with said sealable compartment for creating a condition of negative gauge pressure within said sealable compartment while said cover means and said first and second sealing means prevent replacement of the atmosphere within said sealable compartment.

A bio-hazardous waste compactor comprising:
- a sealable compartment;
- a trash receptacle disposed in said sealable compartment;
- a compaction boot movable into and out of said trash receptacle;
- reciprocating means extending into said sealable compartment for reciprocally moving said compaction boot into and out of said trash receptacle;
- means in fluid communication with said sealable compartment for transporting atmosphere from said sealable compartment and providing a condition of negative gauge pressure in said sealable compartment;
- filter means in fluid communication with said sealable compartment for removing bacteria and other particles from atmosphere transported from said sealable compartment;

- a trash receptacle disposed in said sealable compartment;
- a compaction boot movable into and out of said trash receptacle;
- reciprocating means extending into said sealable compartment for reciprocally moving said compaction boot into and out of said trash receptacle;
- means disposed beneath said sealable compartment for measuring a weight of bio-hazardous waste in said sealable compartment when said sealable compartment is sealed;
- means associated with said weight measuring means for displaying said weight of said bio-hazardous waste;
- means in fluid communication with said sealable compartment for creating a condition of negative gauge pressure within said sealable compartment;
- and
- sealing means associated with said sealable compartment for preventing replacement of the atmosphere within said sealable compartment when said sealable compartment is under said condition of negative gauge pressure.

A bio-hazardous waste compactor comprising:
- a sealable compartment;
- a trash receptacle disposed in said sealable compartment;
- a compaction boot movable into and out of said trash receptacle;
- reciprocating means extending into said sealable compartment for reciprocally moving said compaction boot into and out of said trash receptacle;
- means operatively connected with said reciprocating means for overriding said reciprocating means when said receptacle is not disposed in the sealable compartment to allow reciprocation of said compaction boot when said trash receptacle is not disposed in said sealable compartment;
- and means in fluid communication with said sealable compartment for creating a condition of negative gauge pressure within said sealable compartment;
- and
- sealing means associated with said sealable compartment for preventing replacement of the atmosphere within said sealable compartment when said sealable compartment is under said condition of negative gauge pressure.
