Interventional blood pump

The utility model relates to an intrusive blood pump which comprises a pump body and a driving unit (6), and the pump body comprises an impeller (4), a blood flow guide pipe (3), a blood flow inlet structure (2) and a blood flow outlet structure (5) which are in driving connection with the driving unit. Wherein the blood flow outlet structure (5) comprises an outlet shell (52), an outlet base (54) and a guide vane structure (56) arranged on the outlet base and connected with the outlet shell, and at least one part of the impeller (4) is contained in the outlet shell (52). The guide vane structure (56) is arranged to be able to convert rotational movement of blood flowing out of the impeller (4) into predominantly axial movement. The blood flow outlet structure with the guide vane structure can effectively promote the regularity of a blood flow field and reduce the destructive effect on red blood cells by controlling the flowing direction of blood pumped out by the impeller. 本实用新型涉及一种介入式血泵，包括泵体和驱动单元(6)，所述泵体包括与
