In article approach to creation of the mechatronic unite of system of the auxiliary blood circulation (ABC) on the basis of the reversive executive mechanism and the high-torque, low-speed engine is offered. As the executive mechanism it is offered to use a spatial cam which is set in motion from rollers established on a rotor of the electric motor of an original design. Geometrical parameters of the cam mechanism are received in result of the carried-out synthesis on the basis of the known exponential law of emission of blood from the left ventricle of heart. Schedules of laws of movement and the speeds considering radius of a role on three intervals of interaction of a roller and a cam are received: when approaching roller to a forward edge of a cam, at movement of a roller on top of a cam and, at last, at a descent of a back edge of a cam from a roller. Use received the law will allow to avoid rigid blows and to increase mechanism service life. By results of the carried-out synthesis, and proceeding from constructive reasons, ABC mechatronic unite configuration on the basis of the spatial cam mechanism and the high- torque engine was developed.
