ABSTRACT:
Apparatus for the insufflation of gas, particularly carbon dioxide, into the human or animal body, by means of which the gas is passed from a pressurized gas reservoir, preferably via one or more intermediate reservoirs and at least one pressure reducer, into a line and an insufflator, e.g. a Veress needle, the intraabdominal static pressure being measured by means of the apparatus. A gas flow regulator is positioned in the line between the pressure reducer and the insufflator. Downstream of the flow regulator is positioned a pressure gauge, whose measured value is fed as a function of time into an electronic evaluation circuit and is converted into the intraabdominal pressure.
