Embodiment approach 1
[0069] figure 1 It is a side view showing the state of use of the biological information measuring device according to the embodiment of the present invention. figure 2 is shown in detail figure 1 Partial front view of the biological information measuring device shown. image 3 is as figure 1 A perspective view of the detection part of the contact piece of the biological information measuring device shown. Figure 1 ~ Figure 3 In , components having the same functions are denoted by the same symbols, and repeated explanations are omitted.
[0070] Such as figure 1 As shown, the biological information measuring device 1 of the present invention is, for example, desktop, has a prism 4 as a contact member that contacts the lip mucosa 3 of the lower lip 2, and an arm 5 with the prism 4 at the front end, as figure 2 shown. Although not shown in the figure, a light source is built in, and the light from the light source is incident on the prism 4, and the first light that di...
Embodiment approach 2
[0083] Use Figure 6~ Figure 8 A biological information measuring device according to Embodiment 2 of the present invention will be described. Fig. 6 is a perspective view of a contact used in Embodiment 2 of the present invention.
[0084] In this embodiment, as an example, it will be described that the concentration of a specific component called glucose is measured by bringing the contact member into contact with a biological tissue as a measurement object.
[0085] The light source 11 is preferably a light source that generates mid-infrared light, for example. For example, a light source such as tungsten or SiC is preferable. Especially when measuring glucose and other absorption wavenumbers at 1000cm -1 ~1180cm -1 , and then at 1080cm -1 and 1033cm -1 These light sources are best used when the concentration of the substance is high. This light source can also be used in other embodiments of the invention.
[0086] As the material constituting the contact member 12...
Embodiment approach 3
[0098] use Figure 8 A biological information measuring device according to Embodiment 3 of the present invention will be described. Figure 8 is a probability cross-sectional view of the contacts in the biological information measuring device according to Embodiment 3 of the present invention.
[0099] The light 32 emitted by the light source 31 is emitted in all directions, but it is preferable to use a curved mirror or a lens (not shown) to converge these lights as much as possible, and simultaneously enter the light input portion of the contact member 33 as parallel light (the second light) 40.
[0100] However, when the light source 31 is not a point light source, it is difficult to make the light 32 perfectly parallel, so the incident angle θ of the light incident on the contact portion 34 is not constant. Therefore, there is Figure 8 The angle of incidence θ shown in 1 The light, which reaches the photodetector 36 through the light output part 35, often has a great...
