Title:
SPHYGMOMANOMETER AND METHOD FOR MEASURING BLOOD PRESSURE
Document Type and Number:
WIPO Patent Application WO/2024/057620
Kind Code:
A1
Abstract:
This sphygmomanometer (100) is provided with a blood pressure measurement unit (220) that measures a blood pressure of a user on the basis of a pulse wave signal during a pressurization process of increasing a cuff pressure indicating an inner pressure of a cuff (20) worn on a part of the user to be measured. The blood pressure measurement unit (220) sets a pressurization speed during a predetermined period of the pressurization process lower than the pressurization speed during a period other than the predetermined period of the pressurization process. The predetermined period is set on the basis of a timing at which the amplitude of the pulse wave signal during the pressurization process takes the maximum or a timing at which the cuff pressure during the pressurization process takes an average blood pressure of the user. The sphygmomanometer (100) further comprises a determination unit (230) that determines arrhythmia of the user on the basis of the pulse wave signal during the pressurization process.
