  • Sterilization device for sterilization of lumen devices
    Patent number: 7300638
    Abstract: An apparatus for the sterilization of lumen devices. The apparatus for sterilizing lumen devices is comprised of a chamber defining a region for sterilization, an expansion tank assembly, and a mixing member. The chamber is adapted to receive the expansion tank. The expansion tank is adapted to fluidly connect to at least one lumen device. The mixing member is disposed within the expansion tank to mix gaseous sterilant within residual gas that may include contaminants.

  • High capacity flash vapor generation systems
    Patent number: 7157046
    Abstract: A flash vaporizer (34) provides a constant flow of vaporized hydrogen peroxide or other antimicrobial compounds for rapidly sterilizing large enclosures (10), such as rooms or buildings. The vaporizer includes a heated block (50) which defines an interior bore or bores (70, 72, 74). The flowpath created by the bore or bores increases in cross sectional area as the hydrogen peroxide passes through the block to accommodate the increase in volume during the conversion from liquid to gas. The vapor is injected into dry air in a duct that circulates it to the large enclosure.
