    • 专利摘要:
    A double pump adapted for use as an artificial heart includes two ventricle-simulating chambers that are provided with respective inlets and outlets having valves incorporated therein and that are separated by a common partitioning wall structure. The wall structure has sections that are driven away from each other to reduce the volumes of respective ventricle chambers and expel liquid from the chambers through the outlets. The wall structure can also move laterally in response to differences in pressure between the chambers and hence change the volumetric ratio between them. This ensures a balanced action between the two halves of the heart- simulating pump during a systole phase and a diastole phase. The link mechanism is actuated by a cord through a motor, although only in one direction in the pressure phase, and hence the aforementioned changed volumes are readjusted primarily through the pressure exerted by the inflowing fluid. The pump may also include a variable volume atrium-simulating chamber communicating with the inlet to each ventricle-simulating chamber and having volume that is controlled in part by an externally acting gas pressure that varies in accordance with changes in the volumes of the ventricle chambers.

    Claim
    1. An artificial heart that contains at least two adjacent chambers with an inlet and outlet for liquids, in which valves and an actuator are installed that provides reciprocating movement of the working fluid, the chambers being artificial ventricles and atria, the chambers have a common wall contains at least one section configured to move and forming a cavity with the wall of the corresponding chamber, while the cavity of one chamber communicates with the cavity of another chamber and with the drive of the working fluid , Characterized in that, with the aim of bringing the work is1618276

    to the physiological heart by balancing the flow in the chambers and ensuring a smooth flow during bullet-. sirukyatsem discharge, the common wall has the ability to move and is equipped with
    two flexible sections that can move
    [2]
    2. Heart by π. 1, that is, in that the two flexible sections have spring means.
