BLOOD PUMP CONTROL SYSTEM AND METHOD FOR CONTROLLING A BLOOD PUMP

摘要

Methods are provided for controlling the speed of a pump based on a valve state index and/or for deriving a valve state from time-series signal representing a pressure difference or a flow rate. The methods may be employed in blood pump systems or in blood pump control systems.

1. A method for generating a signal indicative of a valve state, the method comprising:
receiving a time-series signal representing a pressure difference between a first blood pressure and a second blood pressure over at least one heartbeat cycle; deriving at least one signal characteristic from the time-series signal; classifying the valve state of a heart valve during the at least one heartbeat cycle based on the at least one signal characteristic; and generating the signal indicative of the valve state based on the classification.
