PULSE WAVE PROPAGATION TIME MEASUREMENT DEVICE AND BLOOD PRESSURE MEASUREMENT DEVICE

WIPO Patent Application WO/2020/013006

A1

A pulse wave propagation time measurement device according to one aspect of the present invention is provided with: a belt part to be wound around a measurement site of a user; an electrode group provided on the belt part and comprising a first electrode, a second electrode, a third electrode, and a fourth electrode; a current source for applying an alternate current between the first electrode and the second electrode; a potential difference signal detection unit for detecting a potential difference signal between the third electrode and the fourth electrode; an electrocardiogram acquisition unit for acquiring an electrocardiogram which is a waveform signal representing the electrical activity of the user's heart on the basis of the potential difference signal; a pulse wave signal acquisition unit for acquiring a waveform signal representing the electrical impedance at the measurement site of the user as a pulse wave signal on the basis of the potential difference signal; and a pulse wave propagation time calculation unit for calculating the pulse wave propagation time on the basis of the electrocardiogram and the pulse wave signal.
