Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same reference numerals are attached to the same structural elements, and overlapping descriptions are omitted.

[0025] The pulse sensor according to the present invention is assembled and used in, for example, a watch-type living body information measuring device having a pulse measuring function and a time keeping function, or a living body information measuring device having a tablet shape. Hereinafter, as an example, a pulse sensor incorporated in a wristwatch-type biological information measuring device will be described.

[0026] figure 1 It is a partial cross-sectional view showing a pulse sensor and its surroundings according to an embodiment of the present invention. Such as figure 1 As shown, the pulse sensor 1 includes a sensor substrate 10 , a light emitting element 20 and a reflected light detecting element 30 . The sensor su...

Abstract

A pulse wave sensor includes a sensor substrate that has a first main surface and a second main surface that are in a front-back relationship with each other, has formed therein a first opening part and a second opening part that pass through the first and second main surfaces, and includes a non-transparent portion at least between the first opening part and the second opening part, a light emitting element disposed within the first opening part and having a light emitting surface, and a reflected light detection element having a detection surface on which light reflected after being emitted from the light emitting surface of the light emitting element is incident.

Description

technical field [0001] The present invention relates to a pulse sensor for optically measuring the pulse of a detection subject, and a biological information measuring device using the pulse sensor. Background technique [0002] When the heart contracts and blood flows from the left ventricle to the aorta, the internal pressure of the aorta changes, and the change in internal pressure is transmitted to the peripheral arteries. Capturing changes in the pulsation (pulse) of the blood vessels that occur with the outflow of blood from the heart as a waveform is called a pulse. It can be said that information having the same meaning as an electrocardiogram is obtained indirectly by measuring not the beating of the heart itself but the volume change of the peripheral vascular system. [0003] In the pulse measurement using photoelectric conversion, the wrist, finger, or earlobe of the detection target is used as the measurement site, and a pulse sensor having a light emitting ele...
