The system consists of a rigid chamber (1) inside which a bag (2) is placed containing the perfusion liq. By means of a liq. or gaseous interphase a common volume is formed with another chamber (3), with which it is in communication and which acts as a pump or impeller. The chamber (1) incorporates a membrane (4) which possesses high distension capacity and acts on the walls of the bag (2), the residual air being extracted by suction through air vent (8). This is equipped with a valve (5), and the perfusion liq. flows out through the connection line (6) to the patient, a gate valve (7) being provided in the communication line between compartments (1,3).
