Abstract

Provided are a pulse wave detection device and biological information measurement device which make it possible to flexibly change the state of pressing against a body surface by a sensor unit used bybeing pressed against the body surface, and to improve the accuracy of pulse wave detection. A biological information measurement device is provided with: a sensor unit 6 having element rows 60, 70,which are composed of a plurality of pressure detection elements lined up in a direction B, and which are arrayed in a direction A; an air bag 2 for pressing the sensor unit 6 against a body surface of a body in a state where the direction B intersects with a direction in which arteries under the body surface extend; a rotation mechanism 5 for causing the sensor unit 6 to rotate about a first axisX extending in the direction B; and a rotational drive unit 10 for driving the rotation mechanism 5. The rotation mechanism 5, the air bag 2, and the sensor unit 6 are arrayed in the stated order inthe direction of pressing by the air bag 2.

Description

technical field [0001] The invention relates to a pulse wave detection device and a biological information measuring device. Background technique [0002] A biological information measuring device capable of measuring biological information such as pulse, heart rate, or blood pressure using information detected by the pressure sensor in a state where the pressure sensor is brought into contact with the body surface of a biological part through which arteries such as the radial artery of the wrist pass known (refer to Patent Documents 1 and 2). [0003] Patent Document 1 discloses a biological information measuring device, which includes: a pressure sensor having a plurality of element columns composed of a plurality of pressure detection elements; a pressing part for pressing the pressure sensor; a rotation mechanism that rotates with an axis extending in a direction in which the plurality of element rows are arranged (direction perpendicular to the artery); and a drive uni...
