PURPOSE: To avoid influence of recirculation and heighten the efficiency by operating an artery pump and a vein pump at a higher transport efficiency at the time of starting the respective pump phases. CONSTITUTION: A pressure sensor 31 provided in an artery leg 35 or a vein leg 35 is connected to a control unit 25 through an adjusting device 37 for adjusting the making connection of each pump 30, 49. The adjusting device 37 is operational-connected to the pumps 30, 40 disposed opposite to each other. Accordingly, the adjusting device 37 is operated with the maximum transport capability at the time of starting the making connection operation, and subsequently the making connecting operation of the pump can be adjusted to lower lower the transport capability to keep constant transport capacity. Thus, an effective blood flow from a patient or to a patient can be enlarged to the maximum to remarkably heighten the efficiency. |
