Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0019] A blood flow guiding device for a centrifugal magnetic levitation artificial heart pump, including a rotor thrust disc and a guide wire on the disc, such as figure 1 Shown is the structural diagram of the blood flow guiding device of the magnetic levitation centrifugal pump. The rotor thrust disc 1 rotates around the column in the middle of the shell. Due to the application of the magnetic levitation bearing, there is a gap between the rotor thrust plate 1 and the shell. When the rotor thrust plate 1 rotates, the blood is sucked in from the inlet, reaches the blood outlet along the arrow in the figure, and flows out along the outlet; in addition, a small part of blood enters the box and dotted line area in the figure, and due to the pressure difference, it flows from the rotor to the center The gap between the fixed shafts flows from bottom to to...
