Embodiment Construction
[0017] Such as figure 1 As shown, the artificial heart blood pump disclosed by the present invention mainly includes an outer shell 7 and an inner shell 9. Both the outer shell 7 and the inner shell 9 are cylindrical and made of medical titanium alloy TC4. The outer casing 7 is set outside the inner casing 9 to form a sandwich, and the motor stator 8 is placed in the interlayer; one end of the outer casing 7 is sealed and connected with the inner casing 9 by an annular side plate, and the other end is sealed and connected with the inner casing 9 by an annular end cover 11. The inner shell 9 sequentially places the head support assembly 1 , the rotor assembly and the tail support assembly 15 , and the rotor assembly is supported between the head support assembly 1 and the tail support assembly 15 . Among them, the head support assembly 1 is composed of the head hemodynamic pressure suspension cone bearing 2 and the head guide vane 5, the head hemodynamic pressure suspension con...
