  • Patent number: 8337717
    Abstract: The present invention provides for a method of generating an aqueous solution comprising chlorine dioxide using a chlorine-containing chemical oxidant; an effector having the capacity to reduce said chlorine-containing chemical oxidant; a chemical reductant; and water, and operating in either batch or continuous-flow modes. In batch mode, the aqueous chlorine dioxide solution can be generated in a sprayer device, a bottle, or a bucket to disinfect objects by spraying and wiping, by pouring, or by immersion, respectively. In continuous-flow mode, the aqueous chlorine dioxide solution can be generated in flow tubes or continuous-stirred tank reactors, then placed inside a suitable sprayer device, bottle, or bucket.

  • Patent number: 8182715
    Abstract: This invention comprises a lightweight, portable chemical combination of reagents for sterilizing or disinfecting objects in the absence of electrical power or fire. The chemical combination includes a chemical oxidant with the capacity to liberate a biocidal intermediate, a chemical reductant of the oxidant with the capacity to react with the oxidant, and an effector to induce a reaction between the oxidant and reductant. In one embodiment, the oxidant comprises chlorite, the reductant comprises sulfite, and the effector comprises ascorbate. In another embodiment, the chemical combination comprises the oxidant, reductant, effector and iron-activated magnesium. When water or water solutions are added to either embodiment, the chemical combination generates heat, steam and a biocidal intermediate that can destroy contaminating microorganisms. In one embodiment, the biocidal intermediate is a halogen-based biocidal intermediate, such as chlorine dioxide.

  • Patent number: 8133449
    Abstract: A portable, lightweight, easy-to-carry, reusable, durable, and environmentally-friendly assembly for sterilizing contaminated equipment using conditions of a chemical sterilant, heat, and humidity generated in situ without requiring external electricity, fuels, or other exogenous energy sources for operation. The carry assembly includes a plastic carry-case or insulated aluminum pressure vessel having an inner chamber for accepting microbiologically contaminated objects, a vessel disposed in the chamber for serving as a reaction chamber and/or boiler, a chemical combination which upon mixing generates at least minimally sufficient conditions of the sterilant, heat, and humidity to effect sterilization of the objects, and outlet valves mounted on the carry-case for controllably venting pressures above ambient air pressure.
