Blood Pump And Driving Device Thereof

A blood pump (100) and a driving device (10) thereof. The driving device (10) comprises a driving shell (11), a rotor (12), a stator mechanism (13), and an electric wire (17); the driving shell (11) is provided with a mounting cavity (11a) and an accommodating cavity (114) which are separated from each other; the rotor (12) comprises a rotating shaft (121) and a magnetic assembly, the rotating shaft (121) is capable of rotating relative to the driving shell (11), and the magnetic assembly is fixedly connected to the rotating shaft (121); the stator mechanism (13) is accommodated in the mounting cavity (11a), the stator mechanism (13) is capable of generating a rotating magnetic field for driving the magnetic assembly to rotate, and the magnetic assembly is capable of driving the rotating shaft (121) to rotate around the axis of the rotating shaft (121); the part of the electric wire (17) located between the magnetic assembly and the driving shell (11) is accommodated in the accommodating cavity (114), so that the cavity wall of the accommodating cavity (114) prevents the electric wire (17) from contacting the magnetic assembly.
