Interventional blood pump comprising magnetic drive

The invention relates to an intrusive blood pump which comprises an impeller sleeve (4), a first rotating shaft (2), an impeller (3) arranged in the impeller sleeve (4) and fixedly arranged on the first rotating shaft (2) in a sleeving mode, and a motor used for driving the impeller (3) to rotate. The motor comprises a motor shell, a second rotating shaft (12) arranged in the motor shell, a rotor (13) fixedly arranged on the second rotating shaft (12) in a sleeving mode, and a stator (14) coaxially arranged with the rotor (13) and surrounding the rotor (13). A second magnet (10) is arranged on the second rotating shaft (12) and can generate a rotating magnetic field when being driven by the second rotating shaft (12) to rotate, and a first magnet (6) is arranged in the impeller (3) and can drive the impeller (3) to rotate under the action of the rotating magnetic field; and the first rotating shaft (2) and the second rotating shaft (12) are different rotating shafts. 本发明涉及一种介入式血泵，包括叶轮套筒（4），第一转轴（2），设置在所述叶轮套筒（4
