Title:
BLOOD PRESSURE MONITORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/080329
Kind Code:
A1
Abstract:
Provided is a blood pressure monitoring device that can reduce a burden on a living body and estimate blood pressure at short intervals.　According to the blood pressure monitoring device 10, a unique relationship generation unit 92 generates a unique relationship of a living body between a blood pressure value AP, a compressive pressure Pc, and a pulse wave propagation velocity PWV by applying a measured blood pressure value APR, actual compression pressures PcH1 and PcH2 in a low pressure section, and actual pulse wave propagation velocities PWV1 and PWV2 in the low pressure section, to a pre-stored linear relationship between a value obtained by squaring pulse wave propagation velocities PWV2 detected under a plurality of compression pressures Pc of a compression band and an arterial penetration pressure (=blood pressure AP-compression pressure Pc) in the low pressure section in which a pressure is lower than a minimum blood pressure value DAP for the living body. The blood pressure estimation unit 94 calculates an estimated blood pressure value APe for the living body by sequentially applying, to the linear relationship, actual compression pressures PcHm and actual pulse wave propagation velocities obtained in the low pressure section.
