The invention relates to a measuring member and a device to be used for determining the blood flow of the gastrointestinal tract, said measuring member comprising an intestinal probe, having its distal end provided with a flexible inflatable body and at least one pressure sensor mounted on this supporting body. After bringing the inflatable flexible body at the predetermined pressure, the pressure sensor 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 help of the device 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, which represents a measure for the intestinal peristalsis.

L'invention concerne un organe et un instrument de mesure destinés à être utilisés pour déterminer l'écoulement sanguin du tractus gastro-intestinal, ledit organe de mesure comportant une sonde intestinale, dont l'extrémité distale possède un corps gonflable flexible et au moins un capteur de pression monté sur ce corps-support. Après avoir amené le corps flexible gonflable à la pression prédéterminée, le capteur de pression aboute la paroi intestinale, et l'évolution de la pression mesurée, qui représente une mesure de l'écoulement sanguin du tractus digestif, est transformée en une image graphique à l'aide du dispositif et/ou est transformée en valeurs concrètes pour l'écoulement sanguin du tractus gastro-intestinal. De plus, l'organe de mesure selon l'invention mesure l'évolution de la pression à l'intérieur du corps flexible gonflable, ce qui représente une mesure du péristaltisme intestinal.
