Publication number: 20080152539Abstract: 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.Type: ApplicationFiled: December 20, 2007Publication date: June 26, 2008Applicant: OLYMPUS MEDICAL SYSTEMS CORPORATIONInventors: Shinichiro KAWACHI, Eiri SUZUKI, Shintaro SUZUKI
