After bringing the inflatable flexible body (2) at the predetermined pressure, the pressure sensor (5) will abut the intestinal wall and the measured pressure development, which represents a measure for the blood flow of the gastrointestinal tract, is transformed into a graphical image with the 10 help of the device (4) and/or is transformed into actual values for the blood flow of the gastrointestinal tract. Further, the measuring member measures the development of the pressure within the inflatable flexible body (2), which represents a measure for the intestinal persistalsis. 15 Fig. 11/1 Fig. 1 5 6 3 Fig. 2 6 3 1 /6 Fig. 3 2 Fig. 4 7 kw8
