SPHYGMOMETRIC ELECTRODE UNIT, AND SPHYGMOMETER

摘要

A sphygmometric electrode unit (200) is equipped with a plurality of electrodes (41-46) including a pair of electrodes for current application and a first pair of electrodes for voltage measurement, a support member (210) for supporting a plurality of electrodes on a first main surface (211) side opposite the body surface of a measurement subject when being worn by the measurement subject, and a fluid bag (24) configured to be inflatable and deflatable that presses the plurality of electrodes (41-46) toward the body surface of the measurement subject by inflating during measurement. The support member (210) has a length direction that is a circumferential direction when worn by the measurement subject and a width direction (W) that is orthogonal to the length direction (L) and the thickness direction. The plurality of electrodes (41-46) are arranged side-by-side in the width direction (W). A low-rigidity portion having lower rigidity than a portion overlapping an electrode in the thickness direction is provided between each adjacent electrode.
