Sphygmomanometer, blood pressure measurement method, blood pressure measurement program, learning model construction method, and learning model construction program

A blood pressure measurement method comprising:

• controlling, by a computer, pressure applied to an arm of a measurement subject by a cuff wound around the arm;
• detecting, by the computer, cuff pressure received by the cuff from the arm;
• measuring, by the computer, blood pressure of the measurement subject by an oscillometric method by using a time-series change in the cuff pressure;
• correcting, by the computer for a subject, the blood pressure measured in the measuring based on an error output by a correction model, by inputting the information of the waveform related to the time-series change in the cuff pressure detected in the detecting to the correction model constructed by machine learning using information of a waveform related to the time-series change in the cuff pressure as an explanatory variable and using an error of blood pressure measured in the measuring with respect to blood pressure adopted as a true value as an objective variable;
• and
• outputting, by the computer, the blood pressure corrected in the correcting.

A non-transitory computer readable medium storing a blood pressure measurement program for causing a computer to execute:

• controlling pressure applied to an arm of a measurement subject by a cuff wound around the arm;
• detecting cuff pressure received by the cuff from the arm;
• measuring blood pressure of the measurement subject by an oscillometric method by using a time-series change in the cuff pressure;
• correcting, for a subject, the blood pressure measured in the measuring based on an error output by a correction model, by inputting the information of the waveform related to the time-series change in the cuff pressure detected in the detecting to the correction model constructed by machine learning using information of a waveform related to the time-series change in the cuff pressure as an explanatory variable and using an error of blood pressure measured in the measuring with respect to blood pressure adopted as a true value as an objective variable;
• and
• outputting the blood pressure corrected in the correcting.
