Endoscope washer disinfector and method of controlling the supply of the cleaning and disinfecting agent used thereby

摘要

In an endoscope washer disinfector, a liquid agent is supplied from a tank (11) to a washing bath (5). A first supply passage (16) communicates between the tank and a pressurizing member (22, 19, 17). A second supply passage (12) communicates between the washing bath and the tank. A discharging member (17, 28, 27) opens the inside pressure of the tank to the atmosphere. A detector (13) 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 (S1) starts agent supply from the tank to the bath via the second supply passage. Based on the detection signal, means (S4) 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 (55) ends the agent supply by making the inner pressure of the tank open to the atmosphere by driving the discharging member.
