Kind Code:
A1
Abstract not available for EP1284755
Abstract of corresponding document: WO0191810
A pulsed polychromatic light passthrough sterilization device (100) comprising a housing (102) having a first opening (105) accessible from a non-sterile environment (248) and a second opening (107) accessible from a substantially sterile environment (250). The housing includes a volume within the housing extending from the first opening (105) to the second opening (107). A transmissive barrier (114) is positioned within the housing, wherein the transmissive barrier defines a sterilization chamber (228) as a portion of the volume that is within the transmissive barrier. One or more flashlamps (210) are positioned within a lamp chamber (230) of the housing, wherein the lamp chamber is defined as another portion of the volume that is between an inner surface of the housing and the transmissive barrier. The one or more flashlamps (210) produce short duration, high intensity pulses of polychromatic light. Cooling means (222) are coupled to the lamp chamber for cooling the one or more flashlamps. A first door (104) is adapted to fit the first opening, wherein the first door has an open position and a closed position, wherein the closed position seals the sterilization chamber from the non-sterile environment. And, a second door (106) is adapted to fit the second opening, wherein the second door has an open position and a closed position, wherein the closed position of the second door seals the sterilization chamber from the substantially sterile environment.
