ENDOSCOPE REPROCESSOR AND ACTUATION METHOD FOR ENDOSCOPE REPROCESSOR

An endoscope reprocessor includes: a pump; a port; a tube connected to the port; a connector disposed in the tube and connected to a pipe sleeve of a treatment instrument channel, which is a pipe of an endoscope, and configured to allow a fluid to be leaked from a connection region of the connector to the pipe sleeve to an outer circumferential surface of the pipe sleeve; a valve disposed in a flow path; a pressure sensor configured to measure a pressure of the fluid; and a processor configured to repeatedly control the valve such that the valve is closed when the pressure exceeds a first pressure and the valve is opened when the pressure is lower than a second pressure, and determine a feeding state of the fluid based on a time period until an opening/closing number of the valve reaches a predetermined number more than one.
