Problems solved by technology

With this structure, although the optical probe 1 can be miniaturized, the optical probe 1 cannot be easily assembled.
In addition, the protection part 16 (contact part) of Patent Document 1 itself suppresses the transmission of light, and the detection accuracy of the biometric information detector is not high.

Embodiment Construction

[0042] Next, this embodiment will be described. In addition, this embodiment described below does not unduly limit the content of the present invention described in the claims. In addition, all the configurations described in this embodiment are not necessarily essential technical features of the present invention.

[0043] 1. Optical device (living body information detector)

[0044] 1.1 The first structure example

[0045] figure 1 of (A), figure 1 (B) shows a structural example of the optical device of this embodiment. In addition, in figure 1 of (A), figure 1 In (B), the size of each part does not exactly represent the actual size. That is, in figure 1 of (A), figure 1 In (B), the size of each component is enlarged or reduced for easy understanding of the following description. figure 1 of (A), figure 1 Drawings other than (B) do not show exact dimensions similarly.

[0046] Such as figure 1 of (A), figure 1 As shown in (B), the optical device has a...

Abstract

The invention provides an optical device and a biological information detector. The optical device including a contact part having a contact surface and an opposing surface, the contact surface coming into contact with a test subject and the opposing surface being opposite the contact surface; a support body installed on the opposing surface; a first element supported by the support body; and a second element disposed between the opposing surface and the support body; wherein one of the first element and the second element is a light-emitting element for emitting light towards a detection site of the test subject; another of the first element and the second element is a light-receiving element for receiving reflected light, the reflected light being light emitted by the light-emitting element and reflected at the detection site; and the contact part is formed from a material that is transparent with respect to a wavelength of the light emitted by the light-emitting element.

Description

technical field [0001] The present invention relates to an optical device, a living body information detector and the like. Background technique [0002] The biological information measuring device measures biological information such as a person's pulse rate, oxygen saturation in blood, body temperature, heart rate, etc., and an example of the biological information measuring device is a pulse meter that measures the pulse rate. In addition, a biological information measuring device such as a pulse rate meter may be incorporated in electronic equipment such as a clock, a mobile phone, a pager, or a personal computer, or may be combined with electronic equipment. The biological information measurement device has a biological information detector for detecting biological information. The biological information detector has: a light emitting element that emits light toward a detected part of a subject (user); and a light receiving element that receives light from the detected ...
