Document Type and Number:
WIPO Patent Application WO/2018/180375
Kind Code:
A1
Abstract:
[Problem] To provide a biological information measurement device capable of reliably measuring pulse waves, changes in pulse beat and other biological information without resorting to oversized or high-cost devices. [Solution] This biological information measurement device is provided with: a light emission element for emitting measurement light of a predetermined wavelength; a light reception element for receiving return light from the measurement light via a subject; a biological information measurement unit for measuring biological information of the subject on the basis of the result of light reception by the light reception unit; a light emission control unit for causing the light emission element to emit the measurement light at times separated by predetermined intervals; and an attachment determination unit that, when measurement light is emitted at the predetermined intervals under the control of the light emission control unit, determines the state of attachment to the subject on the basis of the amount of return light, corresponding to measurement light for each emission time, received by the light reception element.
