Blood pressure estimation device

Abstract

A blood pressure estimation device includes a display unit (10), a belt portion (20), a first contact electrode (61) and a second contact electrode (62) for detecting an electrocardiographic waveform, and a pulse wave sensor. The display unit (10) displays a blood pressure estimation result. The belt portion (20) is connected to the display unit (10) and surrounds a target measurement site. The pulse wave sensor includes a pulse wave detection unit (40E) that detects a pulse wave of an artery (91) passing through the target measurement site. The first contact electrode (61) and the pulse wave detection unit (40E) are provided on an inner circumferential portion (20a) of the belt portion (20). The second contact electrode (62) is provided on an outer circumferential portion (20b) of the belt portion (20). The first contact electrode (61) and the pulse wave detection unit (40E) are provided in a position where the first contact electrode (61) and the pulse wave detection unit (40E) are to be pressed against the target measurement site when the second contact electrode (62) is pressed from an outer circumferential side of the belt portion (20).
