Abstract
A blood pump includes a hollow body in which an impeller with blading is provided for producing an axial propulsion of blood along the impeller. An at least partly actively stabilised magnetic bearing device is provided wherein the impeller may be set into a rotation about a rotation axis of the impeller, with a motor stator. The hollow body has an inlet for the flow of blood into the hollow body in an inflow direction which is essentially parallel to the rotation axis, and an outlet for the outflow of the blood out of the hollow body in an outflow direction.
Claims17
A blood pump, comprising a hollow body, in which an impeller with a blading is provided for producing an axial propulsion of the blood along the impeller, wherein the impeller is configured to be set into a rotation about a rotation axis of the impeller with a motor stator, and wherein the hollow body comprises a hollow cylinder and an inlet for the flow of blood into the hollow cylinder in an inflow direction which is essentially parallel to the rotation axis, and an outlet for the outflow of the blood out of the hollow cylinder in an outflow direction, wherein the outlet is arranged offset to the rotation axis of the impeller, for producing an outflow angle between the inflow direction and the outflow direction, said angle being different from zero, wherein, at an outlet-side end of the hollow cylinder, an inner radius of the hollow body is enlarged and forms a discharge channel, and a cross-sectional area of the discharge channel enlargens from a beginning of the discharge channel towards the outlet.
