Patent ID: 7465428

Claim:
A system for generating an oxygen-rich gas, comprising: a housing, a puncturing mechanism, a first cartridge sized to fit within a first portion of the housing, the first cartridge comprising: a first rigid water containment chamber having a first gas exhaust opening positioned in a top portion of the water containment chamber, a first flexible chemical storage pouch positioned within the first water containment chamber, a first pressure delivery channel coupled to the first flexible chemical storage pouch and adapted to couple with the puncturing mechanism, a first foam breaker positioned in an upper portion of the first water containment chamber, a first filter positioned above the foam breaker, a second cartridge sized to fit within a second portion of the housing, the second cartridge comprising: a second rigid water containment chamber having a second gas exhaust opening positioned in a top portion of the water containment chamber. a second flexible chemical storage pouch positioned within the second water containment chamber, a second pressure delivery channel coupled to the second flexible chemical storage pouch and adapted to couple with the puncturing mechanism, a second foam breaker positioned in an upper portion of the second water containment chamber, a second filter positioned above the foam breaker and below the second gas exhaust opening, a manifold fluidly coupling the first gas exhaust opening and to the second gas exhaust opening, wherein each of the first and second flexible chemical storage pouches comprise: a flexible oxygen releasing powder storage pouch comprising: a first side sheet, a second side sheet, a bottom seal coupling the first side sheet to the second side sheet, a catalyst storage chamber positioned within the flexible oxygen releasing powder storage pouch and adjacent to the bottom seal, the catalyst storage chamber comprising: a first web sheet positioned between the first side sheet and the second side sheet, a second web sheet positioned between the first side sheet and the second side sheet, and a web seam coupling the first web sheet to the second web sheet, such that in a first position the web seam faces an interior of the flexible oxygen releasing powder storage pouch.
