Abstract

A medical apparatus for supplying fluids into body cavities includes a controllable fluid pump, a memory device, a feed line, a pressure sensor in the feed line, a medical instrument to be connected to the feed line. The pressure measured by the pressure sensor is an input variable of a mathematical estimation system, which mathematically describes a state space, which estimates the actual pressure in the body cavity and controls the output of the pump by means of this estimated value. The resistance coefficients ζ1 and ζ2 of the medical instrument required for the estimation of the pressure are determined when starting the pump. The pressure behavior is evaluated for a certain time, therefrom a characteristic curve is determined, and the characteristic curve is stored in a memory device of the pump.
