摘要： A physiological information measurement device includes: a pressure controller executes a measurement of increasing or decreasing an applied pressure of a cuff with respect to a predetermined site of a subject from an initial value; a pulse detector detects a pulse from a pressure received by the cuff from the predetermined site; a pulse determination unit determines whether the pulse detected by the pulse detector is a correctly detected pulse; a blood pressure calculation possibility determination unit determines whether calculation of a blood pressure of the subject is possible based on the pulse detected by the pulse detector; and a blood pressure calculator calculates the blood pressure of the subject based on a plurality of the pulses determined to be correctly detected by the pulse determination unit.

摘要： A control device is configured to: cause an inflating/deflating device to initiate a first air feeding to a cuff with a prescribed flow rate; calculate an estimated value of a capacity volume of the cuff based on a time length for which the internal pressure inflates from a first value to a second value; cause the inflating/deflating device to perform at least air exhausting before an inflation of the internal pressure reaches a steady state to deflate the internal pressure; determine, based on the estimated value, an air feeding flow rate for obtaining a prescribed inflating speed; cause the inflating/deflating device to initiate a second air feeding to the cuff with the air feeding flow rate before the internal pressure reaches zero; and measure blood pressure of the subject while the second air feeding is performed.
