Beschreibung
Zusammenfassung:	Provided is an interventional blood pump, comprising a pump body and a driving unit (6). The pump body comprises an impeller (4), a blood flow catheter (3), a blood flow inlet structure (2), and a blood flow outlet structure (5) which are in driving connection to the driving unit (6), wherein the blood flow outlet structure (5) comprises an outlet housing (52), an outlet base (54), and a guide vane structure (56) arranged on the outlet base (54) and connected to the outlet housing (52). At least a part of the impeller (4) is accommodated in the outlet housing (52). The guide vane structure (56) is configured to be capable of converting the rotational motion of the blood flowing out of the impeller (4) into a primarily axial motion. The blood flow outlet structure (5) with the guide vane structure (56) can effectively promote the regularity of a blood flow field and reduce the destructive effect on red blood cells by means of controlling the flow direction of blood pumped out by the impeller (4).
