Abstract: Disclosed is a blood pump device. The blood pump device includes: a housing having an overflow passage, and an inlet and an outlet respectively connected to the overflow passage; a rotor assembly rotatably disposed in the overflow passage; a coil disposed in a side wall of the housing; a first permanent magnet portion disposed inside the rotor assembly; a second permanent magnet portion disposed in the side wall of the housing, the first permanent magnet portion and the second permanent magnet portion forming a radial permanent magnet bearing; a piece of electric motor magnetic steel disposed inside a rotor of the rotor assembly; and a magnetic protection portion disposed at a periphery of the coil, wherein the magnetic protection portion and the electric motor magnetic steel act together to provide an axial pre-tightening force for the rotor assembly.

Abstract: A blood pump control system includes a local processing terminal and a remote processing terminal. The local processing terminal is configured to transmit to the remote processing terminal, collected current state parameters of the blood pump and heart activity indexes, and to drive and control the blood pump according to blood pump adjusting parameters received from the remote processing terminal. The remote processing terminal is configured to obtain current blood pump adjusting parameters according to the current state parameters, and the heart activity indexes received from the local processing terminal, and set adjusting conditions; and to transmit the blood pump adjusting parameters back to the local processing terminal.
