1. A heart pump having a bearing device, the bearing device comprising:
a stand unit;
an impeller; and
an intermediate space formed between the impeller and the stand unit for conducting a flushing fluid flow from a fluid;
wherein the stand unit comprises a subsection enclosed by the impeller and configured to align the impeller about an axis of rotation,
wherein the impeller is configured to rotate about a longitudinal axis aligned with the axis of rotation when the heart pump is in operation to convey a pump fluid flow of the fluid in a flow direction,
wherein the impeller comprises at least one flushing outlet for discharging the flushing fluid flow from the intermediate space,
wherein the at least one flushing outlet comprises a first discharge opening for discharging the flushing fluid flow, which has an opening cross-section in which, an opening cross-section normal vector faces away from the axis of rotation and is radial to the axis of rotation,
wherein the impeller is disposed in a housing section comprising at least two second discharge openings for discharging the pump fluid flow and connected to an inlet hose for supplying the fluid, and
wherein the opening cross-section normal vector intersects with one of the at least two second discharge openings of the housing section at a time and is perpendicular to the axis of rotation.
