The invention relates to an embedded micro streamline axial flow blood pump, which can be used for assisting blood circulation of failed heart. The blood pump comprises a pump body arranged in a sleeve body and a driving device arranged outside the pump body, wherein the pump body comprises the sleeve body, a front guide vane, a rotor and a back guide vane; the hubs of the front guide vane, a rotor and the back guide vane are designed integrally in an integral streamline form; and the front half part of the rotor is provided with an inductive blade. The blood pump can reduce the on-way pressure loss of the blood in the flow channel of the blood pump, improve efficiency and reduce hemolysis; and can promote the circumferential speed of the blood after entering into a rotor area due to the inductive blade arranged on the front half part of the rotor, and avoids the occurrence of vacuole phenomenon.
