Abstract
A device for insufflating gas into a corporeal cavity of a human or animal body has 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 corporeal cavity, and a control unit, to which the output signal of the sensors are applied, and which triggers a pressure regulator which reduces the fill pressure of the gas source to a pre-set insufflation pressure, and a flow regulator which regulates the fill gas flow to a pre-set desired gas flow value in accordance with first a square function, and then, after reaching the preset flow rate, in accordance with a linear function.
