Abstract

The apparatus comprises a tube (1) for the passage of the blood in flow, one end (2) of which is capable of being connected onto a catheter introduced into the vein circulation and the other onto a catheter introduced into the artery circulation. This tube has at least one fastening device (4) allowing the mounting of miniaturised sensors in contact with the blood in flow. The apparatus is preferably made of a synthetic and non-thrombogenic material. It allows the observation of numerous parameters and of their development. <IMAGE>
