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 ?1 and ?2 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.

Abstract: The present disclosure is directed to an insufflator which includes a controller, an insufflation line, a desufflation line, and one pressure sensor and one volume flow sensor associated with each of the insufflation and desufflation lines. The insufflation line is in fluid communication with a gas source and the desufflation line in fluid communication with a suction pump. Wherein the controller controls ventilation of a gas present in patient by adjusting an amount of suction in the desufflation line as a function of pressure measurements obtained from the pressure sensors associated with the insufflation and desufflation lines. Additionally, the controller includes an activation blocking system that prevents suction in the desufflation line when a pressure measured by means of the pressure sensor associated with the insufflation line is lower than a preset threshold value.

Abstract: Disclosed are methods for measuring and controlling the gas temperature in medical procedures. In embodiments of the disclosed methods a gas is supplied to a patient using a gas supply device and a supply line. A heating system heats the gas using a heating wire prior to the gas being provided to the patient. A controller electrically controls the heating power of the heating wire based on an estimated value of a temperature at an exit of the heating system obtained from a mathematical estimation system, wherein a resistance of the heating wire is an input variable of the mathematical estimation system.

Abstract: Disclosed is a method for determining and controlling the internal body pressure during a medical procedure that includes controlling the output of a fluid pump by means of an estimated pressure value, wherein resistance coefficients ?1 and ?2 of a medical instrument required for the estimation of the pressure value are determined by evaluating a pressure behavior during pump start up.
