Abstract

The present invention provides a pulse wave detection device capable of improving the detection accuracy of a pulse wave, and a biological information measuring device including the pulse wave detection device. The pulse wave detection unit (100) includes: a sensor unit (6), an element row (60, 70) is formed by a plurality of pressure detection elements arranged along the direction (B), and the two element rows (60, 70) are along The direction (A) perpendicular to the direction (B) is arranged; and the air bag (2) presses the sensor part ( 6). The arrangement interval (distance L1) of the two element rows (60, 70) in the direction (A) is not less than 5 mm and not more than 15 mm.

Description

technical field [0001] The present invention relates to a pulse wave detection device and a biological information measurement device. Background technique [0002] There is known a biological information measuring device capable of measuring 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 living body part through which arteries such as the radial artery of the wrist pass. and other biological information (see Patent Document 1). [0003] Patent Document 1 discloses a biological information measurement device having a driving unit that surrounds a pressure sensor having a plurality of element rows composed of a plurality of pressure detection elements in a direction that is in the same direction as the arrangement direction of the plurality of element rows. The axis extending in the orthogonal direction (orthogonal to the artery) is rotated. This b...
