The utility model discloses a magnetic field drive type blood pump which comprises a pump body, a liquid drawing block arranged inside the pump body and a driving magnet arranged outside the pump body, the pump body is provided with a liquid inlet end and a liquid outlet end, the liquid drawing block is a permanent magnet, the outer side face of the liquid drawing block is tightly attached to the inner side face of the pump body, and the liquid drawing block can do relative movement or sliding in the pump body. A liquid passage arranged in the length direction of the pump body is arranged in the liquid drawing block, the liquid passage is a special-shaped passage, and when the liquid drawing block moves or rotates, a pressurization effect is generated so that liquid in the pump body can be pumped to the liquid outlet end from the liquid inlet end of the liquid drawing block through the liquid passage. According to the magnetic field driving type blood pump, linear motion or rotation of the liquid drawing devi
