Integral artificial heart device capable of storing venous blood in dynamic atria, without interrupting the continuous return of the blood. The device comprises a right ventricle (A1) and left ventricle (A2) pulsing simultaneously, and the reactive right atrium (C1) and left atrium (not illustrated) thereof, immersed in a pneumatic spec (D) having a variable vacuum D, which is driven by a solenoid (35), acting sequentially, by repulsion, on the permanent magnet discs (20, 21) included in the elastic ventricular membranes (18, 19), which beat simultaneously in the ventricular spaces (A1) and (A2), and, in the opposite direction, in pneumatic space (D) which houses elastic tubes acting as atria. The device simultaneously ejects systolic volumes, and accepts the proportion of continuously returning venous blood to store in the atria, during the systole, such that said continuous return is not interrupted by sequential systolic closure of the intake ports.
