A system and method are disclosed for controlling blood flow or flow of biologic fluid in an artificial organ or extracorporeal blood circuit. Selected parameters relating to blood flow are sensed and used to automatically optimize blood flow while assuring proper and safe operation. Utilized in conjunction with a reciprocating dialyzer apparatus (21), the system controls blood flow into and out of the dialyzer apparatus by controlling pressure on a slurry around the dialyzer membrane package. Slurry pressure is controlled by an actuator (16), such as a bellows pump, the pumping action of which is controlled by an electric motor (21), which motor, in turn, is electrically controlled by a control unit (29) which receives sensed indicators of blood flow, pressure and/or motor current. Blood contamination is also monitored for assuring safe operation of the dialyzer apparatus. |
