Abstract: An apparatus for washing and disinfecting an endoscope is provided. First and second chemicals and dilution water, which dilutes the chemicals to be used for disinfecting the endoscope, are charged into a tank. The tank includes a first portion, a second portion having an area of base smaller than that of the first portion, a first sensor detecting that the dilution water is charged into the first portion up to a first level, a second sensor detecting that the first chemical is charged into the second portion up to a second level, and a third sensor detecting that the second chemical is charged into the second portion up to a third level. A unit measures a first volume of the first chemical based on a result of the second sensor and measures a second volume of the second chemical based on results of the third sensor and the second sensor.

Abstract: An endoscope washer disinfector comprises a chemical cassette, a loading unit, and a chemical tank. The chemical cassette is charged with a chemical. This chemical cassette has a delivery port to deliver the chemical therethrough. The loading unit allows the chemical cassette to be detachably loaded thereto and is formed to deliver the chemical in the chemical cassette when the chemical cassette is loaded. The loading unit comprises a blade used to forcibly open the delivery port and to sense whether or not the chemical is delivered to the chemical tank via the opened delivery port. The chemical tank stores the chemical delivered from the chemical cassette loaded to the loading unit.

Abstract: In an endoscope washer disinfector, a liquid agent is supplied from a tank to a washing bath. A first supply passage communicates between the tank and a pressurizing member. A second supply passage communicates between the washing bath and the tank. A discharging member opens the inside pressure of the tank to the atmosphere. A detector detects an amount of the agent passing along the second supply passage to output a detection signal corresponding to the agent amount. By driving the pressurizing member to pressurize the inside of the tank via the first supply passage, means starts agent supply from the tank to the bath via the second supply passage. Based on the detection signal, means determines whether the amount of the agent passing along the second supply passage reaches a specified volume. When it is determined that the agent amount reaches the specified volume, means ends the agent supply by making the inner pressure of the tank open to the atmosphere by driving the discharging member.
