The programming of a cleaning and disinfection (11) for an endoscope (69) prescribes a number of successive steps whereby the channels of the endoscope are flushed by various fluids under pressure, introduced via supply channels (72-78). The permeability and/or fluid tightness of an endoscope channel is tested by 1) pressurising the channel, 2) shutting off the supply channel, and 3) assessing whether the time elapsed between the shut-off and the moment when the pressure of the flushing fluid drops below a predetermined value is inferior to a predetermined time interval. A flow-through test unit (71) is provided with a number of outlets (79-85), connected to the channels of the endoscope (69) for cleaning and disinfection, and a number of inlets (87-90), connected to a system of pipes, pumps (98) and valves (39-42). Each channel which is connected to an endoscope channel, contains a pressure sensor (92-97) fitted between the valve (39-42) and the outlet (79-85). <IMAGE> |
