Embodiment 1
[0046] figure 1 Shown is a magnetically driven high-flow pulsatile blood pump according to a preferred embodiment of the present invention, which includes four magnetic driving devices 1 and a sheet metal casing 2 covering the outside. Figure 2 ~ Figure 4 It is a schematic diagram of the installation of the magnetic propulsion device 1 , the magnetic propulsion device 1 is fixed on the support surface of the installation bracket 3 and works in linkage with the drive assembly 4 below, and is covered by a cover plate 5 above.
[0047] Each magnetic propulsion device 1 includes a driving coil 11 , a two-way joint 12 , an inner capsule 13 and a magnetic shielding cylinder 14 . Figure 5 It is an explosion schematic diagram of a single magnetic propulsion device 1 (inner capsule 13 sees Figure 6 ). The drive coil 11 is in the shape of a cylinder, and the inside is a blood pumping cavity. For the setting of the drive coil 11 and its control circuit, please refer to the patent CN...
