Abstract: Disclosed is a device for insufflating gas into a corporal cavity of a human or animal body having a connection for a gas source, a measuring unit provided with sensors for the fill gas pressure and the fill gas flow, which are disposed outside said corporal cavity, and a control unit, to which the output signal of the sensors are applied, and which triggers a pressure regulator which reduces or regulates the fill pressure of the gas source to an insufflation pressure (desired gas pressure), which can be set, and a flow regulator which regulates the fill gas flow to a value (desired gas flow), which can be set.
