  • Patent number: 6986736
    Abstract: A method detects proper connection of fixtures to one or more channels in an endoscope during a cleaning or disinfection procedure. The endoscope has a first opening into one of its channels. The method includes the steps of placing the endoscope at the first opening in a liquid while leaving a gas within the channel, drawing a vacuum on the gas through a second opening into the channel and thereby drawing some of the liquid into the channel, and detecting for air leaking into the channel.

  • Patent number: 6939519
    Abstract: The present invention provides a power feedback control system for controllably maintaining a predetermined average power value of a power applied to a plasma of a sterilization system. The power has a frequency of from 0 to approximately 200 kHz. The power feedback control system includes a power monitor including a current monitor and a voltage monitor. The current monitor is adapted to produce a first signal indicative of a current applied to the plasma. The voltage monitor is adapted to produce a second signal indicative of a voltage applied to the plasma. The power monitor is adapted to produce a third signal in response to the first signal and second signal. The third signal is indicative of the power applied to the plasma. The power feedback control system further includes a power control module adapted to produce a fourth signal in response to the third signal from the power monitor and to a reference signal corresponding to the predetermined average power value.

  • Patent number: 5667753
    Abstract: An apparatus and process for hydrogen peroxide vapor sterilization of medical instruments and similar devices make use of hydrogen peroxide vapor released from an inorganic hydrogen peroxide complex. The peroxide vapor can be released at room temperature and atmospheric pressure; however, the pressure used can be less than 50 torr and the temperature greater than 86.degree. C. to facilitate the release of hydrogen peroxide vapor. The heating rate can be greater than 5.degree. C. Optionally, a plasma can be used in conjunction with the vapor.
