  • Patent number: 5686045
    Abstract: Methods for sterilizing an instrument contaminated with biological matter are disclosed. The apparatus generally includes a container for containing a room temperature antimicrobial solution and a lid that can seal the container such that a gas is trapped within the container and above the antimicrobial solution. The apparatus provides a pressure, independent of heat, within the sealed container to greater than one atmosphere. Vibration is also provided to vibrate the container, and its contents, such that biological matter on the instruments is removed and all microbes on the instrument are exposed to the antimicrobial solution. The pressure drives and forces the antimicrobial solution into the cracks and crevices of the instrument and also into the outer membrane of the microbe, which can be first softened or attenuated by the vibrations.

  • Patent number: 5683655
    Abstract: The apparatus of this invention can be used to disinfect a writing instrument used by a health care professional when working with a patient. The apparatus includes an absorbent material pad that has a breach formed, for example, with a slit or a series of slits extending entirely through the pad. The pad is soaked with disinfecting fluid, and a writing instrument is inserted through the breach in the pad to disinfect the writing instrument. To hold the pad in a fixed position, the apparatus includes a holder with first and second members that can be joined together or separated to allow insertion or removal of the pad. The first and second members of the holder define respective apertures that are aligned with the breach in the pad when the first and second members are joined together to enclose the pad.

  • Patent number: 5288462
    Abstract: A sterilization apparatus has a chamber within a housing in which the materials to be sterilized are placed and the chamber is supplied with liquid under pressure. A pressure sensitive, rapid acting implosion cartridge is in communication with the chamber and acts to depressurize the chamber in milliseconds when the desired sterilization pressure is reached. The cartridge then reseals the chamber for a subsequent pressure build-up.
