The extracorporeal blood circuit (1) is connected to the blood system of a patient and contains in front of and behind the dialyzer (2) a blood pump (3,4). Between the two blood pumps and the dialyzer is connected a sensor device (5,6) in the extracorporeal blood circuit. The dialyzer fluid circuit (7) contains similarly on both sides of the dialyzer a fluid pump (8,9). At a position in the flow direction behind the dialyzer branches a by-pass conduit (10), in which is connected an ultrafiltration pump (11). In the flow direction behind the one fluid pump (8) and before the other fluid pump (9) and the ultrafiltration pump sensors (12,13,14) are arranged. The sensors measure the flow amount and determine the concentration of substances dissolved in the fluid. |
