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: A method is provided for controlling the gas temperature in medical devices by means of a state observer, e.g., in the field of laparoscopy or respiration, and to devices for carrying-out said method.

Abstract: The invention relates to a method for determining compliance of a cavity in minimally invasive surgery and to devices for carrying out said method.

Abstract: The present disclosure relates to a medical apparatus for use in laparoscopic surgery, that includes an insufflator supplying a gas; a heating and humidification system which includes a heating element and humidification material, the heating and humidification system receives the gas supplied by the insufflator and warms and humidifies the gas; and a computing device for measuring at two or more time periods a resistance value associated with a component of the heating and humidification system and based in part on the measured resistance values, determines a water content of the humidification material.

Abstract: The invention relates to a method for determining cavity volumes of rubber-elastic medical products (e.g., latex products) for destruction-free leakage testing and to devices for carrying out said method.
