AI Technical Summary
Technical Problem
Current technology cannot accurately determine the placement of the catheter pump, which could potentially damage the heart and aorta, and relying on doctors' experience is not reliable enough.
Method used
By using the pump's own motor and pressure sensor to acquire current and pressure signals, and combining these signals with specific thresholds and frequency ranges, the position of the pump's blood outlet and inlet relative to the aortic valve can be determined, thus enabling the placement of the pump.
Benefits of technology
This enabled accurate determination of the catheter pump placement location, reduced the risk of hemodynamic support failure due to incorrect placement, and improved surgical safety.

Abstract
The application provides a catheter pump placement position judgment method, system, electronic equipment and medium. First, the catheter pump is started and controlled to operate at a predetermined rotating speed. Then, a current signal of a motor of the catheter pump and a pressure signal of a pressure sensor of the catheter pump within a predetermined time are acquired. The position of a blood outlet and a blood inlet of the catheter pump relative to an aortic valve can be judged based on the acquired current signal and pressure signal. The application only uses the data of the motor and the pressure sensor of the catheter pump, does not need to introduce other invasive measuring equipment, is beneficial to the doctor to quickly and accurately judge the placement position of the catheter pump, reduces the risk that the catheter pump cannot provide effective blood flow dynamics support due to the incorrect placement position of the catheter pump, and can directly and accurately reflect the state of the heart, greatly improving the safety of the operation.
