AI Technical Summary

Technical Problem

Traditional catheter pump position judgment relies on DSA imaging technology, which has problems with radiation risks and prolonged surgical time. The interference between the guidewire and the impeller causes the motor to be unable to start, which restricts position judgment.

Method used

The position determination device of the conduit pump is used to collect the speed data of the drive motor, calculate the extreme difference value, judge the position status of the conduit pump, avoid interference between the guide wire and the impeller, and use the unique through-channel design of the guide wire.

Benefits of technology

It realizes accurate position judgment without additional sensors or multiple contours, reduces radiation risks, simplifies operating procedures, and improves positioning accuracy and safety.

Abstract

The invention relates to a catheter pump position judgment device and method, a catheter pump, a ventricular assist system, a storage medium and equipment.The catheter pump position judgment device comprises a sampling module, a processing module and a judgment module, and the sampling module is configured to collect operation data of a driving motor of the catheter pump in the conveying process; the operation data at least comprises rotating speed data; the processing module is configured to determine a range value of the rotating speed data; the judgment module is configured to determine the position state of the catheter pump according to the comparison result of the range value and a preset threshold value. The method does not need to depend on an additional pressure sensor or multiple times of radiography, and can judge whether the catheter pump is located in the aorta, the transvalvular position or the left ventricle by collecting the rotating speed data of the driving motor and analyzing the range value of the rotating speed data.
