  • Patent number: 8684233
    Abstract: A fluid container unit including: a container coupling for coupling a supply/discharge port of a first container with a supply/discharge port of a second container; a single nozzle member having a nozzle tube; a connection cap having a first end for holding a base portion of the nozzle member and a second end for covering one side of the container coupling by fitting around an outer periphery thereof; an intermediate adaptor having a pair of pusher elements facing the first and the second supply/discharge ports, respectively; and a supply/discharge port opening mechanism for moving the intermediate adaptor toward the container coupling and opening the supply/discharge ports by the pusher elements. The pusher elements are movably held in a direction along a longitudinal axis of the nozzle tube in the connection cap.

  • Patent number: 7824608
    Abstract: An apparatus washes/disinfects, at a time, a plurality of endoscopes having a plurality of channels with different diameters, and dewaters the channels at a time. For the dewatering, the apparatus includes plural ports for receiving air supply, and a plurality of tubes for connecting between each of the plurality of ports and each of the plurality of channels in each of the plurality of endoscopes. The apparatus also includes an on-off valve for intermittently supply air to the ports, and a control unit for opening/closing the valve a plurality of times at a predetermined ratio. Water droplets remaining in a large-diameter channel are mainly moved by wind pressure of continuously flowing air while the valve is open, and discharged. Water droplets in a smaller-diameter channel are mainly moved by hammer effect of high-pressure air caused while the valve is closed, and discharged. The valve opening/closing is repeated for complete dewatering.

  • Patent number: 7758704
    Abstract: An endoscope cleaning/disinfecting apparatus of the present invention includes a cleaning tub, a chemical solution tank for storing a germicide, a chemical solution collection pipe, a chemical solution pipe, a feed pipe, a germicide bottle tray which can be drawn from the body of the cleaning/disinfecting apparatus, and a control unit for performing control to prepare the germicide by mixing a basis, a buffering agent, and a diluent. The germicide bottle tray includes a storage part which stores at least a first bottle body out of the first bottle body for storing the basis or a second bottle body for storing the buffering agent, and a detection portion for outputting a detection signal in a state in which the bottle body is stored in the storage part. The control unit performs control based on the detection signal outputted from the detection portion to prepare the germicide.
