    摘要: A blood pump having a pump casing with a blood flow inlet and a blood flow outlet, an impeller arranged in said pump casing so as to be rotatable about an axis of rotation. The impeller has blades sized and shaped for conveying blood from the blood flow inlet to the blood flow outlet. There is a drive unit for rotating the impeller, the drive unit having a magnetic core including a plurality of posts arranged about the axis of rotation and a back plate connecting the posts and extending between the posts in an intermediate area. A coil winding is disposed around each of the posts. The coil windings are controllable so as to create a rotating magnetic field. The impeller has a magnetic structure arranged to interact with the rotating magnetic field so as to cause rotation of the impeller.

    摘要: The invention generally relates to improved medical blood pump devices, systems, and methods. For example, blood pumps may be provided that include a housing defining a blood flow path between an inlet and an outlet. A rotor may be positioned in the blood flow path. A motor stator may be driven to rotate the rotor to provide the blood flow through the pump. Axial and/or tilt stabilization components may be provided to increase an axial and/or tilt stabilization of the rotor within the blood flow path. In some embodiments, biasing forces are provided that urge the rotor toward a bearing component. The biasing force may be provided by adjusting drive signals of the motor stator. Additionally, or alternatively, one or more magnets (e.g., permanent/stator magnets) may be provided to bias the rotor in the upstream and/or downstream direction (e.g., toward a bearing (chamfer, step, conical), or the like).

    摘要: A driving device and a blood pump. The driving device comprises a driving housing, a shaft sleeve assembly, a rotating shaft, a driving component and a sensing assembly. An accommodating cavity and a detection port in communication with the accommodating cavity are provided on the shaft sleeve assembly, and the detection port is located on an outer wall of the shaft sleeve assembly; the rotating shaft is rotatably arranged on the shaft sleeve assembly; the driving component can drive the rotating shaft to rotate; and the sensing assembly comprises a sensor, the sensor comprising a probe, the probe being accommodated in the accommodating cavity, a position of the probe corresponding to a position of the detection port, and the probe being capable of detecting pressure of a fluid outside the driving device.
