  • Publication number: 20170332891
    Abstract: An apparatus is operable to process a medical instrument by passing a detergent and a disinfectant through a plurality of channels defined by the medical instrument. The apparatus includes a detection system, a set of instrument profiles, and a control system. The detection system is configured to collect information regarding the channels of the medical instrument. The control system is configured to pass a detergent and a disinfectant through the channels of the medical instrument based at least in part on a selected instrument profile selected from the set of instrument profiles. The selected instrument profile is selected based at least in part on the information collected by the detection system.

  • Patent number: 7686761
    Abstract: A method detects proper connection of an endoscope to an endoscope processor by measuring pressure pulses applied to the connection point. The method can include measuring for the pressure pulses at a second connection point on the endoscope processor and measuring for a beat frequency produced variations in the frequency of pressure pulses input at each connection point. The method can also include looking for echoes of the pressure pulsations from physical structures within a lumen of the endoscope connected to the connection point.

  • Patent number: 7670550
    Abstract: A method of sterilizing an article includes placing the article into a chamber containing an inner atmosphere and exhausting the inner atmosphere to lower pressure in the chamber. Hydrogen peroxide vapor is present in the chamber during at least a portion of the step of exhausting the inner atmosphere. Exhaustion of the inner atmosphere is terminated and additional hydrogen peroxide is admitted into the chamber. Hydrogen peroxide vapor contacts the article for a sufficient period to effect sterilization of the article.

  • Patent number: 7179419
    Abstract: A method for sterilizing medical devices and similar instruments in diffusion-restricted containers is provided. The sterilization method includes placing a liquid solution containing vaporizable germicide such as hydrogen peroxide into the diffusion-restricted container and vaporizing the germicide. The containers can be attachable and detachable to a sterilization system, and used as a vacuum chamber. An attachable/detachable container containing an article to be sterilized can be nested with a second container, and the article and inside and outside of the inner container are sterilized. The sterile article inside the nested containers can be transported and the sterile inner container with the sterilized article can removed from the outer container and placed in a sterile environment without contaminating the sterile environment. The sterile article can then be removed from the sterile container and utilized.
