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.

Abstract: An endoscope cleaning instrument and an endoscope cleaning apparatus are provided that have a simple configuration and that can be manufactured easily and at a low cost. An endoscope cleaning instrument of the invention cleans a distal end portion of an endoscope by ejecting a fluid fed from a fluid supply section towards a side face and a front face of the distal end portion.

Abstract: A control section reads data such as a conduit diameter and a conduit length of an endoscope and a cleaning profile which are separately recorded in a storage section based on type information of the endoscope registered in the storage section. A cleaning degree suited to the endoscope is estimated by calculation based on a pressure value and a flow rate value which are measured, the diameter and the length of the conduit to be cleaned, and the cleaning profile.

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.
