Problems solved by technology

However, since a single contact element for detecting biological information is used, it is difficult to separate the light passing through the dimple portion 622 from the light passing through the dimple portion 623, so there is a possibility of interference between the two signals

Embodiment 1

[0049] FIG. 1 is a schematic diagram of an optical element for measuring biological information and a biological information measuring device using the optical element in an embodiment of the present invention. As shown in FIG. 1 , a biological information measuring device 100 in this embodiment is formed with a light source 11 , an optical lens 12 , an optical element 13 for measuring biological information, a light separating device 14 , a spectroscopic device 15 and a light detecting device 16 .

[0050]The positional relationship between the light splitting device 14 and the spectroscopic device 15 is not limited to the positions shown in FIG. 1 . The light separating device 14 and the spectroscopic device 15 may be interposed between the light source 11 and the optical element 13 for measuring biological information. In the case where the spectroscopic device 15 and the light splitting device 14 are not used, the spectroscopic function can also be implemented by changing ...

Embodiment 2

[0107] As shown in FIG. 1 in Embodiment 1, the light passing through the first light-transmitting body 17 a , the second light-transmitting body 17 b and the third light-transmitting body 17 c may partially interfere with each other. In order to prevent interference more reliably, the optical element for measuring biological information in this embodiment is formed as shown in FIG. 7 .

[0108] FIG. 7 is a schematic diagram of the optical element 13 for measuring biological information in this embodiment and a biological information measuring device using the optical element. In FIG. 7, the light-shielding body 19 is located between the first light-transmitting body 17a and the two second light-transmitting bodies 17b. Based on this structure, the light-shielding body 19 prevents signals from the first light-transmitting body 17a and the second light-transmitting body 17b from interfering with each other, which is very preferable.

[0109] The light-shielding body 19 is prefe...

Embodiment 3

[0121] As a simpler structure of the optical element for measuring biological information in the present invention, a structure as shown in FIG. 9 is involved. FIG. 9 is a schematic diagram of an optical element 13 for measuring biological information in this embodiment and a biological information measuring device using the optical element.

[0122] In FIG. 9, the light-shielding body 19 is interposed between the first light-transmitting body 17a and the second light-transmitting body 17b. Based on this structure, the light-shielding body 19 prevents signals from the first light-transmitting body 17a and the second light-transmitting body 17b from interfering with each other, which is very preferable.

[0123] Other structures may be the same as those in Embodiment 1 or Embodiment 2 above.

[0124] The biological tissue measured by the optical element for measuring biological information and the biological information measuring device in the present invention is not particul...

Abstract

The present invention provides a bioinformation measuring optical element and bioinformation measuring instrument for measuring optical parameters concerning bioinformation. The bioinformation measuring element is for measuring bioinformation by applying light to an organism and using light absorbed / reflected by a tissue of the organism. The element comprises at least two different light transmitting bodies for applying / receiving light to / from the organism. The light transmitting bodies each has an organism contact portion brought into contact with the organism.

Description

technical field [0001] The present invention relates to an optical element for measuring biological information non-invasively measuring glucose, cholesterol, urea or triglyceride in body fluid by optically measuring biological tissue and a biological information measuring device using the optical element sour fat. Background technique [0002] Generally, a method of measuring biological information by using an optical element including a dimple portion in contact with a surface of a living body has been proposed (for example, Patent Document 1). As shown in FIG. 10, the biological information measuring device disclosed in Patent Document 1 includes a light source 11; having a plurality of concave portions 621, 622, 623, 624, and 625 and convex portions 631, 632, 633, 634 on the surface. , 635 and 636 and a contact element for detecting biological information; a photodetector 16; a signal processing unit 64 and a display device 65. [0003] When using the above-mentioned b...
