Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the drawings.

[0018] Such as figure 1 As shown, a non-invasive detection device for human biochemical indicators with a controllable detection depth. The near-infrared light emitted by the light source 2 is transmitted to the detector 4 via the incident optical fiber 1-1. The detector 4 contacts the human skin surface, and the incident light is projected to the human body The skin surface enters the exit fiber 1-2 after reflection and scattering on the skin surface. The exit fiber 1-2 has three sets of fiber cores with different core distances, and the three sets of fiber cores are respectively conducted to the detector 3-1, In the detector two 3-2 and the detector three 3-3, each detector converts the optical signal into an electrical signal to achieve the purpose of detection.

[0019] Such as figure 2 As shown, the center position of the probe 4 is the incident fiber 1-1, the short cor...

Abstract

The invention discloses a detection depth adjustable non-invasive detection device for human body biochemical criteria, belongs to the field of optical sensing technology, and aims to solve the problem of incapability of specially detecting skin tissues at specific heights in the prior art. Near-infrared light emitted by a light source of the device is conducted into a detection head via an incident optical fiber, the detection head contacts with human skin surface, incident light is projected to the surface of the human skin surface, and enters an emergent optical fiber after being reflected and scattered by the skin surface, the emergent optical fiber comprises three optical fibers with different core distances, the three optical fibers are conducted into a first detector, a second detector and a third detector respectively, each detector converts light signals into electric signals, and detection is achieved. By the device, detection depth adjustable non-invasive detection for the human body biochemical criteria is achieved.

Description

Technical field [0001] The invention relates to a non-invasive detection device for human biochemical indicators with a controllable detection depth, and belongs to the technical field of optics and sensing. Background technique [0002] The biochemical components of the human epidermis are of great significance in clinical and research fields. Among them, moisture, oil, etc. can be used as important indicators for judging the skin quality and health of human skin, and the physiological indicators such as sugar, lipids, hemoglobin in the epidermis and dermis are related to the corresponding indicators in the blood to a large extent. It can obtain blood glucose, blood lipids, hemoglobin and other indicators through optical analysis of the epidermis. [0003] In the near-infrared non-invasive detection of human epidermal biochemical indicators, the near-infrared light is incident on the human epidermal tissue from the light source, absorbed and scattered by the human tissue, and the...
