Claim 9:
10. The device according to claim 1, wherein the first pump comprises:
a Y-shaped inlet duct, for the inlet of the blood aspired from the blood flow of the treated patient, provided with an electrovalve connected to a non-collapsible duct of the first catheter;
a Y-shaped outlet duct, for the outlet of the blood inserted into the blood flow of the treated patient, provided with an electrovalve, connected to the elastic duct of the first catheter;
a machine body containing two internal chambers, separated by a rigid median septum provided with an electrovalve, connected to the inlet and outlet ducts by unidirectional valves, working by difference of pressure, imposing to the blood entering and leaving the two internal chambers to always move in a same direction;
hydraulic cylinders with relative pistons that cyclically manage compression and expansion of an operating fluid that is kept separate from the blood contained in the two internal chambers by elastic membranes; and
an electromechanical mechanism for operating pistons of the hydraulic cylinders, provided with eccentric kinematic mechanism coupled to a frame integral with the pistons and linearly sliding on guides with a stroke limited by cushioning springs.
