Method and device for controlling blood pump, electronic equipment and storage medium

Abstract

The invention provides a method for controlling a blood pump, which comprises the following steps of: obtaining preset target aorta systolic pressure and target aorta systolic flow; on the basis of an iterative algorithm, obtaining the nth aorta systolic pressure and the nth aorta systolic flow detected during the nth iteration; determining an nth pressure difference value based on the target aorta systolic pressure and the nth aorta systolic pressure; determining an nth flow difference value based on the target aorta systolic flow and the nth aorta systolic flow; based on the nth pressure difference value and the nth flow difference value, determining the nth rotating speed of a motor during the nth iteration; determining the nth operation power of the motor matched with the nth rotation speed during the nth iteration, and controlling the motor to operate at the nth operation power; and if the mth aorta systolic pressure detected during the mth iteration and the target aorta systolic pressure meet a first iteration stopping condition and the detected mth aorta systolic flow and the target aorta systolic flow meet a second iteration stopping condition, stopping the iteration.

Description

Technical field [0001] The present application relates not limited to, in particular, in particular, a method, apparatus, electronic device, and storage medium that controls blood pumps, and more. Background technique [0002] The artificial heart is simply referred to as "blood pump", which generally passes through the ventricular auxiliary device to extract from the left ventricle, pressurized to the aorta to assist the cardiac. The correlation speed control method is used to control the blood pump, that is, the blood pump is controlled to rotate at a constant speed to achieve rated operating performance. When the patient's physiological state has improved, the speed is reduced to reduce hemolysis. [0003] However, this manual controlled blood pump work does not only increase human cost, but also problems with complicated manual operation. Inventive content [0004] The present application provides a method, apparatus, electronic device, and storage medium that controls the b...
