Medical device with improved desufflation

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 line and the 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 a 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 line and the desufflation line. 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. Still further, the activation blocking system further prevents suction in the desufflation line when the pressure measured by means of the pressure sensor associated with the insufflation line and a pressure measured by means of the pressure sensor associated with the desufflation line are not identical.
