Abstract
An artificial heart comprising a rigid housing whose dimensions and shape are close to those of the natural heart. A rigid central partition divides the housing into two halves corresponding to the right and left hearts, respectively. Each half is divided by a rigid lateral partition into two chambers. One of these chambers is adjacent to the central partition; this is an auricle chamber. The second chamber is between said auricle chamber and the wall of the housing; this is a ventricle chamber. Each auricle chamber is divided by a flexible diaphragm into two cavities. One of these cavities adjoins the central partition and is intended to contain a working medium. The other cavity adjoins the lateral partition and is intended to receive blood. Each chamber of the ventricle is also divided by a flexible diaphragm into two cavities. One of these cavities adjoins the lateral partition and is intended to receive blood, whereas the second cavity adjoins the housing wall and is intended for the working medium. Installed in each of the lateral partitions are check valves which serve to communicate the blood cavities of the auricle chamber with those of the ventricle chamber and transfer blood from the auricle chamber to the ventricle chamber.
