Abstract
An insufflation device for filling a body cavity, such as an abdominal cavity, with a gas from a gas bottle via an expansion valve and a feed pipe leading to the body cavity characterized by the feed pipe being formed along in length by two channels with the first of the two channels having an expansion valve for setting an overpressure for rapid filling of the body cavity during an initial period and the second channel having an expansion valve to adjust the pressure to the pressure desired in the body cavity. The pressure of the second flow is monitored and compared by an electronic evaluator system, which will interrupt the flow and sound alarms if the pressure exceeds a predetermined amount over the desired value and also if the pressure exceeds a predetermined maximum amount.
