AI Technical Summary
Existing interventional pumps used for cardiac position detection suffer from problems such as large pump head size, complex structure, and high cost, and a single pressure sensor is insufficient to accurately determine the position.
By acquiring the operating signal data of the interventional pump and the blood pressure data of the assisted subject, the cross-pump net pressure data is determined after conversion and processing. The phase information of the blood pressure signal and the cross-pump net pressure signal is used to determine the interventional position status in combination with the phase relationship.
It improves the accuracy of intracardiac pump position detection, reduces misjudgments under abnormal load conditions, simplifies the structure, and reduces costs.
