Abstract
A blood pump with a rotor can be driven to rotate about an axis of rotation for conveying blood. A control is being configured to operate the rotor successively in time, or alternately several times, in a first conveying mode and at least in one second conveying mode. In order to avoid dead water areas in the region of the rotor and possible thrombus formation the direction of rotation of the rotor is reversed in the second conveying mode compared to operation in the first conveying mode.
Claims18
A system comprising:
- a blood pump with a rotor which can be driven to rotate about an axis of rotation for conveying blood;
- and
- a control unit for the blood pump that is configured to operate the rotor in a first conveying mode and at least in one second conveying mode, wherein the second conveying mode comprises a direction of rotation of the rotor is reversed with respect to a direction of rotation of the rotor in the first conveying mode;
- wherein the rotor is configured such that a conveying direction of the blood pump in the second conveying mode is the same as a conveying direction of the blood pump in the first conveying mode.
