  • Publication number: 20050136118
    Abstract: Disclosed herein are germicidal compositions, kits, methods for preparing the germicidal compositions, and methods of using the compositions for disinfection or sterilization. In one aspect, a solid composition may include a solid having water solubility greater than phthalaldehyde, and a germicide diluted in the solid. In another aspect, a kit for preparing a germicide solution may include a germicide, an enhancer for the germicide, and at least two compartments to contain the germicide and the enhancer. In yet another aspect, an apparatus may be used to prepare a germicidal solution. The apparatus may include a first port to receive a first composition including a germicidally effective compound, a second port to receive a second composition including an enhancer for the germicidally effective compound, a source of water, and germicidal solution preparation logic to control preparation of the germicidal solution from the first and the second compositions and the water.

  • Patent number: 6884393
    Abstract: Disclosed herein are methods of sterilizing a device in a sterilizer, methods of sterilizing a device in an enclosure in a sterilizer, and enclosures for retaining a device capable of being sterilized in a sterilization process. The sterilization process comprises hydrogen peroxide vapor or gas. The sterilization load may include an enclosure, which can be a tray or a container. The tray or container comprises at least a volume of aluminum oxide. The ratio of the amount of hydrogen peroxide gas or vapor introduced into the sterilizer to the volume of aluminum oxide is at least 24 mg/cm3.

  • Patent number: 6692693
    Abstract: A sterilization container for sterilizing, storing and transporting instruments is formed of a liquid crystal polymer, such as a wholly aromatic polyester. The container is strong yet has thin walls so that condensation is minimized. Suitable polymers include wholly aromatic polyesters such as: polybenzoate-naphthalate; polybenzoate-terephthalate-bisphenol-isophthalate; polybenzoate-terephthalate-ethylene glycol; and polynaphthalate-amino terephthalate.

  • Publication number: 20030211023
    Abstract: A sterilization container for sterilizing, storing and transporting instruments provides enhanced diffusion. Cut-out portions of the lid sidewalls and base sidewalls interact to form openings through the side of the container. Apertures are also preferably formed through upper and lower surfaces of the container. Such design is particularly useful when the container is formed of a liquid crystal polymer, such as a wholly aromatic polyester.

  • Publication number: 20030192799
    Abstract: A packaging enclosure for receiving a flexible endoscope during a sterilization procedure and sterile storage thereafter has a portion thereof which is semi-permeable. Provision is made for hanging the packaging enclosure over a hook or peg. In one embodiment the packaging enclosure conforms to the endoscope so that its two flexible portions may hang over opposite sides of the hook. Alternatively, a hook or aperture may be provided on the packaging enclosure for hanging it over the hook.
