A flow rate estimation method of a blood pump of the present invention includes a first step which has a step in which a plurality of blood pumps are prepared, and a general flow rate estimation formula which includes a correction term is formed using the plurality of respective blood pumps and a step in which measured data obtained by using the objective blood pump implanted inside a body of a patient is substituted into a correction term, thus forming a flow rate estimation formula of the objective blood pump based on the general flow rate estimation formula, and a second step which estimates the flow rate Q of the blood pump based on the flow rate estimation information formula and the values of N, I and Z of the objective blood pump which are obtained by measuring the rotational speed N of the motor and the consumption current I of the motor of the objective blood pump which is implanted inside the body of the patient, and the attribute data Z of the blood of the patient. Due to the flow rate estimation method of a blood pump of the present invention, it is possible to effectively suppress the deterioration of the accuracy of the flow rate estimation result attributed to the individual difference of the property of the blood pump. |
