Classification: CPC G  A | IPC A  G

Claim 0:
1. A blood pump system comprising:
a fluid pump configured to pump a fluid, the fluid pump including an excitation device, a magnetic bearing, and a delivery element mounted in the magnetic bearing; and
a sensor, a time detection device, or a combination thereof;
wherein a coil of the excitation device is configured to cause an oscillation of the delivery element by generation of a thrust force against the delivery element, the thrust force caused by an application of an excitation signal to the coil of the excitation device;
wherein a coil of the magnetic bearing is configured to apply a counter-force against the thrust force;
wherein the coil of the excitation device and the magnetic bearing are configured to generate the thrust force and the counter-force, respectively, along an axis in which the delivery element is configured to deliver the fluid, wherein the coil of the magnetic bearing is configured to generate the counter-force so as to stabilize a position of the delivery element along the axis, wherein the coil of the excitation device is a second coil of the magnetic bearing;
wherein the sensor is configured to measure an oscillation frequency of the delivery element, the time detection device is configured to measure an oscillation build-up behaviour of the delivery element, the time detection device is configured to measure an oscillation decay behaviour of the delivery element, or any combination thereof.
