Transportable contaminated remains pouch
View Patent ↗A gas-tight, liquid-impervious, transportable contaminated remains pouch designed and configured for storage and/or movement of remains or other items such as evidence in forensic applications that have been or are suspected to have been contaminated.
1. A container for storing or transporting at least one contaminated item, comprising:
a plurality of polymeric, multi-layered chemical composite flexible walls that are impervious to gases and liquid and define an interior chamber that has sufficient dimensions to accommodate said contaminated item;
a gas-tight closable and openable opening for placing and removing said contaminated item in the interior chamber; and an
air management system that filters and releases pressure from the inside of said interior chamber and includes:
a pressure relief valve to allow the release of gasses to prevent over pressurization in the container, and
an air-purifying system that comprises at least one of an air-purifying cartridge or canister to filter air exiting the container through the valve.
2. The container of claim 1 , wherein said at least one contaminated item is a human or animal body, bodily remain, or forensic sample.
3. The container of claim 1 , wherein said multi-layered chemical composite is a thermoplastic resin selected from the group consisting of polyvinyl chloride, chlorinated polyethylene, chlorinated butyl, polyethylene, high density polyethylene, low density polyethylene, linear low density polyethylene, polypropylene, polyurethane, PTFE, combinations thereof, or multiple-layered coextruded films which include one or more layers of ethylene-vinyl acetate, ethylene vinyl alcohol, polyvinyl alcohol, nylon, Surlyn (ionomer), polyester.
4. The container of claim 1 , wherein the air-purifying canister comprises a nuclear, biological, and/or chemical filter canister.
5. The container of claim 1 , wherein the air-purifying respirator cartridge or canister comprises at least one layer of chemsorptive media.
6. The container of claim 5 , wherein the chemsorptive media is activated carbon.
7. The container of claim 5 , wherein the chemsorptive media is nuclear, biological, and chemical absorbent.
8. The container of claim 1 , wherein the container maintains about 4-inch positive air pressure with up to about a 20 percent drop in pressure after four minutes in a standard inflation test.
9. The container of claim 1 , wherein said gas-tight closable and openable opening is a zipper.
10. The container of claim 9 , wherein the zipper comprises PVC, PE, Hytrel, PP, butyl, neoprene.
11. The container of claim 9 , further comprising a thermoplastic interface material that joins the zipper with the multi-layered chemical composite.
12. The container of claim 1 , wherein the multi-layered chemical composite is resistant to at least one of Sarin, Mustard, Soman, nerve agent, Lewisite, tear gas.
13. The container of claim 1 , wherein the multi-layered chemical composite is resistant to toxic industrial chemicals.
14. The container of claim 1 , wherein said multi-layered chemical composite is layered with a thermoplastic polyolefin elastomer layer.
15. The container of claim 1 , wherein said walls form an extended tubular body.
16. The container of claim 1 , wherein said walls are joined by hermetic seams.
17. The container of claim 16 , wherein said seams are sealed with a chemically resistant tape.
18. The container of claim 16 , wherein said seams are sealed with heat, radio frequency welding, or impulse welding.
19. The container of claim 1 , further comprising a polymeric abrasion-resistant fabric surface.
20. The container of claim 19 , wherein the polymeric abrasion-resistant fabric comprises polyvinyl chloride.
21. The container of claim 1 , wherein the interior chamber comprises a super adsorbent polymer.
22. The container of claim 21 , wherein the interior chamber comprises adsorbent pads adhered to the walls that define said chamber.
23. A container for storing or transporting at least one contaminated item, comprising:
a polymeric composite flexible wall that is impervious to gases and liquid and define an interior chamber that has sufficient dimensions to accommodate said contaminated item;
a gas-tight closable and openable opening for placing and removing said contaminated item in the interior chamber; and an
air management system that filters and releases pressure from the inside of said interior chamber and includes:
a pressure relief valve to allow the release of gasses to prevent over pressurization in the container, and
an air-purifying system that comprises at least one of an air-purifying cartridge or canister to filter air exiting the container through the valve.
