Abstract
A heart pump and a method for operating a VAD (ventricular assist device) heart pump, in which method a time-dependent pressure of the blood to be delivered is measured directly by means of at least one pressure sensor arranged on the pump inlet and/or on the pump outlet. A temperature of the blood is additionally detected. By evaluating the measured pressure profiles and/or corresponding rates of change of the measured pressure, it is possible for delivery parameters of the pump, and physiological values of the heart assisted by the pump, to be determined in a convenient and reliable manner.
Claims23
-21. (canceled)
A blood pump comprising:
- a pump inlet;
- a pump outlet;
- at least one pressure sensor;
- and
- at least one temperature sensor,
- wherein the blood pump is configured to directly measure a time-dependent pressure of blood to be delivered by means of the at least one pressure sensor arranged on the pump inlet, the pump outlet, or both the pump inlet and the pump outlet, and wherein the blood pump is further configured to detect a temperature of the blood to be delivered by means of the at least one temperature sensor.
A method comprising:
- receiving blood at an inlet of a blood pump;
- delivering the blood at an outlet of the blood pump;
- directly measuring a time-dependent pressure of the blood with at least one pressure sensor, the at least one pressure sensor arranged on the pump inlet or on the pump outlet or on both the pump inlet and the pump outlet;
- and
- detecting a temperature of the blood with a temperature sensor arranged in or on the blood pump.
