Abstract

An extracorporeal blood circuit in which a blood oxygenator is placed in series between a first and second pump, the pumps being of the peristaltic or ventricular type, the inlet to the first pump being connected to patient's vein and the outlet of a second pump to a patient's artery. The useful internal volume of the body of the first and second pumps varies substantially proportional to the pressure of the blood at the inlet, between minimum and maximum values, the maximum useful volume of the first pump and the minimum useful volume of the second pump being reached at a pressure of the blood at the inlet of the respective pump within a range of atmospheric pressure +/- 20 mm mercury.
