PURPOSE:To prevent the generation of the rising of the internal pressure of a circuit and to eliminate trouble such as the damage of the circuit accompanied by the rising of internal pressure, hemolysis, the extension of the restriction time of a patient or the like by mounting an apparatus capable of controlling a water removing amount to a control means and mounting an apparatus capable of equalizing the flow rate of plasma separated by a plasma separation means and that of the plasma controlled by the control means to a reflux means. CONSTITUTION:A reflux means 6 consists of pumps 61, 62, 63... and tubes 71, 72, 73, 74... and a blood pump 61 is controlled to 0.5-100ml/min, desirably, 10-30ml/min in its flow rate. A plasma pump 62 is controlled to 0.1-100ml/min, disirably 1-50ml/min in its flow rate. A controlled plasma pump 63 is controlled so that the flow rate thereof becomes equal to that of the plasma pump 62. Pref., as the plasma pump 62 and the controlled plasma pump 63, the same pump, for example, a two-throw peristaltic pump is used. In this case, when the same tubes are used as both tubes, the flow rates of both of them can be made equal. |
