Height correction device, altitude correction method and blood pressure measurement system using a height correction device

摘要

A height correction device measures height information about the reference position of the heart and height information about the wrist to which a blood pressure measurement device is attached using communication technology, when a person's body rotates or moves during the measurement time including the sleep time, subjecting the detected blood pressure measurements to altitude correction Using height information, and approximates the detected blood pressure readings to the blood pressure readings measured at the reference position of the heart to thereby obtain highly accurate readings.
