  • Patent number: 8206660
    Abstract: The present invention provides a sterilizer having a housing defining a sterilization chamber. An opening in the housing communicates with the chamber. A surface surrounds the opening, and a door is movable between one of an open position allowing access to the chamber through the opening and a closed position covering the opening. A seal element is associated with the surface for forming a fluid-tight seal between the door and the surface when the door is in the closed position. An operating system is provided for applying pressure to one side of the seal from a first source external to the operating system to force the seal into engagement with the door. Sensing means are provided for monitoring the pressure applied to the seal from the first pressure source. A second source of pressure is provided in the operating system and is connectable to the seal.

  • Patent number: 7265253
    Abstract: Mail which may be contaminated with a biotoxin, such as Anthrax, is received in a preliminary sorting area (16) including a dirty side sorting room (40) that is sealed to the ambient environment. The mail is loaded into a pass-through decontamination system (22) in which the mail is sterilized or otherwise decontaminated. The mail is removed from the pass-through system in a second or clean room (18) which is isolated from the first. The mail is then sorted and processed in the lean room (18). In the event that the sorting room (40) becomes contaminated or is suspected of being contaminated by pathogenic biological or chemical agents, a spray system (86) supplies a decontamination gas into the preliminary sorting area (16) to decontaminate the dirty side sorting room (40), any equipment (42, 44) in the room, and any mail located in the room.

  • Patent number: 7189349
    Abstract: An enclosure assembly (10, 10, 10) includes a framework (12) formed from structural members and a flexible transparent enclosure (14) which provides an enclosed space for isolation and or treatment of patients, equipment, and the like. A treatment material, such as hydrogen peroxide or other gaseous or vapor sterilant, may be fed to the enclosure to microbially decontaminate or otherwise treat the equipment. The enclosure is quickly assembled and disassembled after use, making it suitable for treatment of large pieces of equipment which are not readily moved or which are too large to be accommodated conventional sterilization equipment.

  • Publication number: 20030138344
    Abstract: A system for handling mail is in the form of a modular facility (10), which is capable of being isolated from the surrounding environment. The modular facility includes an enclosure or sorting area (40) for receiving and sorting incoming mail. A decontamination system (22) receives sorted mail and decontaminates the mail with a antimicrobial gas, such as ethylene oxide. A clean room (32), isolated from the enclosure and spaced from the enclosure by the decontamination system, is used for receiving processed mail from the decontamination system and sorting the mail for distribution. A source (92) of a decontaminant gas, such as vapor hydrogen peroxide, is fluidly connected with the enclosure for supplying the decontaminant gas to the enclosure in the event that the sorting room is contaminated or suspected of being contaminated with a pathogenic biological or chemical agent.

  • Patent number: 4650646
    Abstract: An improvement in a process for sterilizing goods comprising a method for substantially reducing condensate on the processed goods. The method includes producing an exothermic reaction during the process between effective amounts of at least two reactants to release at least a sufficient quantity of heat proximate the goods to substantially reduce condensate on the goods at the conclusion of the process. Hydratable salts may be housed in a liner which is permeable to a condensate vapor present in the process. Contact between the vapor, or condensate, and the salt produces the exothermic reaction during the process.

  • Patent number: 4459936
    Abstract: Apparatus for indicating whether the contents of a container have been sterilized during a sterilization process including a first member having a portion for coacting with the sterilization agent to indicate the sterility of the contents of the container. A second member is adapted to extend into the interior of the container to be sterilized and receive and releasably engage the first member so that said first member can be positioned within the interior of the container to be sterilized during the sterilization process and so that the first member can be placed in and withdrawn from the second member without exposing the contents of the container to the surrounding environment or the operator to the contents of the container.

  • Patent number: 4193818
    Abstract: Method and apparatus are provided for ultrasonic cleaning and decontaminating, disinfecting, or sterilizing articles, such as surgical instruments, in a single piece of equipment. Energy transmission through a unitized shell wall coupled with deep vacuum conditions in the chamber enables rapid degasification, enhanced cavitation providing effective and efficient ultrasonic cleaning in a sealed vessel capable of carrying out high pressure sterilization.Sonic energy transducers are rigidly mounted externally of the unitized shell to achieve desired cavitation substantially uniformly throughout the volume of the chamber established for placement of articles to be ultrasonically washed and biocidally treated.
