Abstract

The invention relates to a method and device for insufflating gas, in particular CO.sup.2 into the human or animal body, especially for laparoscope, with an insufflation instrument, for example, a Veress inflow needle, with the following structures arranged successively along a gas line a: pressure reducer 1a throughflow meter and pressure meter and with a control circuit connected with the throughflow meter and a pressure meter via respective control lines. The device is without noise-generating magnetic valves, and the intra-abdominal pressure can be measured continuously without elaborate switch overs. The pressure reducer is electrically controllable and connected with the evaluating and control circuit via a control line and is controllable via control line as a function of a clock generator and a nominal pressure generator. In this device, the apparatus pressure is varied, whereby the nominal pressure is reached more rapidly and sudden gas losses can be accommodated better, while a pure filling process can be carried out continuously as well as an actual pressure measurement and also a test cycle.
