    Abstract: The invention concerns an apparatus for controlled irrigation of the natural cavities and tubes of the human body. It is characterized in that it includes correcting means for equalizing the measuring signal which represents the pressure and which is emitted by a pressure gauge (10) according to the pressure losses and according to the difference of height between the area of measurement of the pressure and the intervention area which corresponds to an organ (2). These correcting means includea correcting circuit (14B) adapted to effect a correction according to said difference of heightand a correcting circuit (14C) adapted to take into account the pressure loss, namely the flow rate of the fluid injected through the inner duct (6) of the endoscope (1) and the cross section of this duct.
