ABSTRACT OF THE DISCLOSURE The invented artificial heart consists of two ventricles and two atria and is designed for inclusion in a blood circulation system via valves to operate in the same manner as a live heart. The heart is made in the form of a rigid housing containing in its top part two inlet ports and two outlet ports. An elastic ventricle and elastic atrium constitute a symmetrical half of the heart. The bottom part of the housing is shaped in the form of two parallel cylinders capped tightly and slidably with buckets having convex bottoms these bottoms forming pistons. An elastic movable diaphragm is located above each piston, this diaphragm being circumferentially attached to the inside of the cylinder and to the elastic ventricle. Physiological liquid is contained between the ventricle and the diaphragm. The top part of the housing is connected with a branched shank designed for attaching to the human skeleton, and the buckets are attached to the branched elastic, membranaceous and pedate bearer designed to rest against respiratory muscles and their bony lining. The volume of ventricles and of atria in the artificial heart is about four times larger in comparison with that of a live heart. The heart is act- uated by the-motion of respiratory muscles which exert a pressure on the buckets via the bearer, the operation of the heart being similar to that of a hydraulic diaphragm-piston pump.
