Abstract

Method for determining the continuity of endoscope channels in which a predetermined fluid amount with a predetermined pressure is fed through a channel to be tested (9) and the resulting time taken to complete the fluid passage measured and evaluated. The predetermined fluid quantity is determined from the volume of the fluid container. The invention also relates to a corresponding device which comprises a fluid container (1), whose outlet is connected to the channel, a compressed air source (12) that acts on the fluid in the container, and a sensor (14) that measures the fluid level in the container and determines when it has fallen below a preset value. A control unit (16) measures the time duration within which a predetermined volume has flow through the channel under test.
