FIELD: medicine, as well as hydraulic systems with pulsating flow and amplitude oscillation process. SUBSTANCE: the offered device provides for creation of an artificial implanted organ of a human-being or animal-artificial hearth pump that can automatically change the rate of pulsation and its amplitude, coordinating these changes with the requirements of the human or animal organism, and prevent mechanical effect of the rotor on blood. A ball-type pump is known, which has a spherical detachable sealed body with ports and a rotor placed in it and formed by a disk and semi-disk hinge-joined to it; the disk divides the body into two hemispheres, one of which has the mentioned ports, and the semidisk divides it into working chambers. Innovation is in the fact that an annular groove is made in the body along the joint line of the hemispheres, the disk mounts the rotor for movement in it, and the hemisphere with ports is filled with working fluid, and its ports are in the same plane with the semi-disk and are fully overlapped by it in the position, in which it is perpendicular to the disk, and hermetically closed by a flexible or superflexible membrane; on the side of the other hemisphere in the central part of the hinge joint of the disk with the semi-disk provision is made for a recess with a rod installed perpendicularly to the longitudinal axis of the mentioned hinge joint and hinge-joined to the carrier, forming a mechanical coupling of the rotor with the rotor drive installed in this hemisphere and changing the angle of inclination of the semi-disk to the disk. EFFECT: improved design. |
