BIOINFORMATION ACQUIRING DEVICE AND BIOINFORMATION ACQUIRING METHOD

摘要

At step S101, pulse data is acquired into a bioinformation acquiring device by means of a pulse data acquiring section. At step S102, the pass frequency band of a bandpass filter (11) is set as the range in which the pulse rate of the subject varies by means of a frequency setting section. At step S103, a specific frequency component of the pulse data acquired at step S101 is extracted by means of the bandpass filter the pass frequency band of which is set at step S 102. At step S104, the rise point of a pulse is detected by means of a rise point detecting section (13). At step S105, the pulse rate at the rise point is calculated from the reciprocal of the interval between the rise points of the pulses determined at step S104 by means of a pulse rate calculating section. At step S106, the pulse data in the interval between adjacent rise points is integrated and the intrapulse integration value of the pulse data is calculated by means of a blood pressure calculating section.
