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 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.
