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...

Abstract

In order to solve the problem of a prior art biological attribute measuring device, i.e., measurement data is apt to vary because of unstable contact due to difficulty in controlling a thickness of a saliva layer and pain caused during the measurement, is provided a biological attribute measuring device including a contact device having a portion, at least part of which is a curved surface, for abutting against a measuring region to apply light to the measuring region, a light detecting means for detecting at least one selected from the group consisting of transmitted light, reflected light, scattered light and transmitted / reflected light from the measuring region and a measuring means for measuring a specific component in the measuring region based on the detection result.

Description

technical field [0001] The present invention relates to biological information measurement for non-invasively measuring biological information such as the blood sugar level of living beings by using transmitted light, reflected light, scattered light or transmitted reflected light. Specifically, the present invention relates to a method for measuring the concentration of a specific component such as glucose, cholesterol, or ethanol, and a contact for concentration measurement used therefor. Background technique [0002] Conventionally, various measurement methods have been proposed for measuring a specific component of an object to be measured, such as a living thing or a solution, using an attenuated total reflectance (ATR) measuring device. [0003] Individuals with severe diabetes have a blood-sampling type blood glucose measuring instrument that is easy to operate, and adopt the method of self-sampling blood glucose measurement. More recently, however, the development o...
