  • Patent number: 6585943
    Abstract: A fluid delivery system (26) for an automated processor (A) delivers washing, microbial decontaminant, and rinse fluids to spray nozzles (102, 104, 106, 108, 110) in a chamber (12) for sequentially spraying the fluids over a lumened device (B), such as an endoscope. The fluid delivery system also delivers the fluids to connection ports (150, 152, 154) which connect with internal passages (187) of the device for delivering the fluids thereto. Leaking connectors (184) connect the automated processor connection ports with inlet ports (196) of the device and allow a portion of the washing, decontaminant, and rinsing solutions to leak from each inlet port. A computer control system (80) controls cleaning, decontamination, rinsing, and drying stages of a cycle, which are all carried out within the chamber, obviating the need for human contact with the device during processing.

  • Patent number: 6558620
    Abstract: A method of washing, microbially decontaminating, and rinsing of a lumened device (B), such as an endoscope includes positioning the device in a chamber (12) of an automated processor (A). Spray nozzles (102, 104, 106, 108, 110) within the chamber sequentially spray washing, microbial decontaminant, and rinse fluids over the device. Fluid connection ports (150, 152, 154) connect with internal passages (187) of the device for delivering the fluids thereto. Leaking connectors (184) connect the automated processor connection ports with inlet ports (196) of the device and allow a portion of the washing, decontaminant, and rinse solutions to leak from each inlet port. A computer control system (80) controls leak testing, cleaning, decontamination, rinsing, and drying stages of a cycle, which are all carried out within the chamber, obviating the need for human contact with the device during processing.

  • Patent number: 6485684
    Abstract: A fluid disinfection or sterilization system includes spray nozzles (26) for spraying an anti-microbial fluid on the exterior of an endoscope (14) supported in a microbial decontamination chamber (10a, 10b). The endoscope includes interior lumens which are microbially decontaminated by flowing anti-microbial fluid from outlets (28) through the lumens. A port (36) is connected with a leak detector. In order to ensure that the proper leak detector and anti-microbial fluid ports of the disinfection or sterilization system are interconnected with the proper lumen ports of the endoscope, a tethered connection assembly (50) is provided. The tethered interconnection assembly includes fittings (60, 62, 64) which are uniquely configured for interconnection with an appropriate one of a high pressure port, a low pressure port, and the leak detector port. Fittings at the other end of the tube assemblies (56) are configured for interconnection with appropriate corresponding ports of the endoscope.
