[A portable, movable pneumatic drive for an artificial heart with an autonomous electrochemical source of energy]. / Portativnyi perenosnoi pnevmaticheskii privod iskusstvennogo serdtsas avtonomym élektrokhimicheskim istochnikom énergii.

The authors have designed a pneumatic drive, which differs from the known ones in that it contains two electromagnetic two-linear and two-positioned air distributors while the motor operates in the mode excluding the change of its axis direction. This affords using a standard crank mechanism as a transformer of rotary motion to translational motion and reducing several times the power consumed. Besides, the two-linear and two-positioned air distributors allow a possibility of exercising a separate control over the time of the systole-diastole phases of the left and right ventricles. In this case both ventricles can work at 100% filling whereby maintaining the capacity of the artificial heart without additional energy consumption.
