Blood pump

The invention relates to a blood pump (1) comprising a hollow body (2), in which an impeller (3) with a blading (4) is provided for producing an axial propulsion of the blood along the impeller (3), as well as an at least partly actively stabilised magnetic bearing device (15, 15', 16, 16'...

More Information
Summary:The invention relates to a blood pump (1) comprising a hollow body (2), in which an impeller (3) with a blading (4) is provided for producing an axial propulsion of the blood along the impeller (3), as well as an at least partly actively stabilised magnetic bearing device (15, 15', 16, 16', 17, 17', 18, 18') and a hydrodynamic bearing device (7) for the impeller, wherein the impeller may be set into a rotation about a rotation axis (R) of the impeller (3) with a motor stator (19) located outside the hollow body, and wherein the hollow body (2) comprises an inlet (5) for the flow of blood into the hollow body (2) in an inflow direction (E) which is essentially parallel to the rotation axis (R), and an outlet (6) for the outflow of the blood out of the hollow body (2) in an outflow direction (A), wherein the outlet (6) is arranged offset to the rotation axis (R) of the impeller (3); for producing an outflow angle ([alpha]) between the inflow direction (E) and the outflow direction (A), said angle being differen
