Abstract
The present blood flow monitoring and control apparatus is especially use in connection with the so-called single needle technique, for example, for treatments such as dialysis, perfusion, or diafiltration. The blood pressure control is accomplished by a measuring chamber including a pressure equalizing device operatively connected between the blood cleaning apparatus and the blood pump. Sensors are operatively connected to the volume measuring chamber. The volume sensors provide electric control input signals to a control circuit which in turn controls the blood pumps and/or valves. A reading may be provided on a display or an alarm may be given when the blood pressure or blood quantity or volume is not within predetermined limits as calculated by an electronic computer.
