ABSTRACT:
An artificial heart comprising two ventricles (8) and two atria (9) adapted for inclusion in a blood circulation system via valves (17), to operate in the same manner as a live heart. The heart comprises a rigid housing (1) containing in its top part two inlet ports (2) and two outlet ports (3). Elastic ventricle (8) and elastic atrium (9) constitute a symmetrical half of the heart. The bottom part of housing (1) is shaped in the form of two parallel cylinders (4) capped tightly and slidably with buckets (5) having convex bottoms, these bottoms forming pistons (6). An elastic movable diaphragm (7) is located above each piston (6), and is circumferentially attached to the inside of cylinder (4) and to the elastic ventricle (8). Physiological liquid is contained between ventricle (8) and diaphragm (7). The top part of housing (1) is connected with a branched shank designed for attachment to the human skeleton, and buckets (5) are attached to the branched elastic, membranaceous and pedate bearer designed to rest against respiratory muscles and their bony lining. The volume of ventricles (8) and of atria (9) is about four times larger in comparison with that of a live heart. The heart is actuated by the motion of respiratory muscles which exert a pressure on buckets (5) via the bearer, the operation of the heart being similar to that of a hydraulic diaphragm-piston pump.
