  • Endoscope washing and disinfecting apparatus and leak detection method performed by the apparatus
    Patent number: 8176771
    Abstract: An endoscope washing and disinfecting apparatus includes: a connecting portion connected to a bending transmitting portion of an endoscope to transmit driving force; a distal end driving portion for transmitting the driving force to the bending transmitting portion through the connecting portion; a fluid supplying unit for supplying gas into an inner space of the endoscope; and a control unit for controlling a pressure detecting portion for detecting pressure in the inner space and the distal end driving portion to provide the bending portion with bending motion, and for determining occurrence or nonoccurrence of water leak in the endoscope by comparing the pressure detected by the pressure detecting portion and a preset threshold.
    Type: Grant

  • ENDOSCOPE WASHING AND DISINFECTING APPARATUS AND ENDOSCOPE WASHING AND DISINFECTING METHOD
    Publication number: 20090220377
    Abstract: An endoscope washing and disinfecting apparatus includes: a fluid supply unit that supplies fluid for washing and disinfecting; an electromagnetic valve provided in each of a plurality of connecting channels which are connected to a plurality of channels of an endoscope; a single flow rate meter provided between the fluid supply unit and the electromagnetic valve; and a flow rate limiting section for limiting flow rate so that the flow rate falls within a flow rate measurement range in which flow rate measurement by the flow rate meter is possible; or a flow rate padding section for padding a flow rate with a flow rate that can be detected by the flow rate meter; or a flow rate diverting section for diverting part of flow rate that flows to the flow rate meter through a bypass channel.
