Insufflator

摘要

The invention relates to an insufflator with a supply connection (22) and a delivery connection (14) and a pressure and flow measuring device arranged between said connections (14, 22) for determining measured quantities characterizing a gas pressure at a delivery connection and a gas volume flow at the delivery connection. The pressure and flow measuring device comprises a multilayer board (20) which comprises on its interior at least one flow channel (26) that is connected at its input to the supply connection (22) and at its output (8) to the delivery connection (14). Arranged on the board (20) are pressure measurement sensors (32, 34) and electronic components (4, 6) for the wiring of the pressure measurement sensors. The pressure measurement sensors are each directly connected to the flow channel (26) via a corresponding opening of a board layer that otherwise tightly covers the flow channel (26) and are designed to provide an output value representing a static pressure at the point of the respective opening.
