Tissue component non-invasive detection device and system, and wearable equipment

Abstract

The embodiment of the invention discloses a tissue component non-invasive detection device and system, and wearable equipment. The device comprises an incidence optical fiber, a detection module and aprocessing module, wherein the detection module is in communication connection with the processing module. The incidence optical fiber is used for emitting incident lights with various preset wavelengths to a detected part; the detection module is used for obtaining intensity values of lights emitted from the surface of the detected part at preset positions according to each preset wavelength andsending each light intensity value to the processing module; and the processing module is used for determining the concentration of tissue components to be detected according to the light intensity value under each preset wavelength. According to the embodiment of the invention, the intensity values of the lights emitted from the detected part can be directly processed, so that light loss is reduced, and detection efficiency is further improved. As the volume of the detection device is greatly reduced, the device is easy to wear and fix on a part to be detected, and stability of detection conditions can be ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of spectral detection, and in particular, to a high-precision wearable non-invasive detection device, system and wearable device for tissue components. Background technique [0002] The body fluids of the human body contain a variety of tissue components, such as blood sugar, fat, and white blood cells. The concentration of each tissue component must be within its corresponding concentration range to ensure the healthy operation of the human body. However, for some individuals, because their tissue components are prone to imbalance, that is, the concentration of tissue components is not within the range of values, which will cause the body to suffer from diseases, endanger health or even life. Perform real-time detection. [0003] Because the optical method has the characteristics of rapidity, non-invasiveness and multi-dimensional information, the prior art usually adopts the optical ...

AI Technical Summary

Problems solved by technology

[0004] However, it is found that at least the following problems exist in the prior art: one, the signal-to-noise ratio is low

Since the diffusely scattered light emitted by the tissue to be measured is relatively weak, the change of the diffusely scattered light caused by the concentration change of the tissue components to be measured is also weak, and the light receiving efficiency is low. Therefore, the signal of the received diffusely scattered light signal The noise ratio is low, which directly affects the detection accuracy of the tissue components to be tested, resulting in low detection accuracy; second, the detection conditions vary greatly

Since the tissue to be tested is soft tissue, each time the detection device is placed on the measured site for measurement, due to the different detection conditions, the change of diffuse scattered light caused by the detection conditions is much greater than that caused by the concentration of the tissue components to be measured. Changes in diffuse scattered light caused by changes, the above-mentioned results in low detection accuracy

Among them, the detection conditions can include the incident position of the incident light, the incident angle of the incident light, the contact pressure and the temperature of the measured part; third, the background noise of the measured individual itself is large

The water, fat and protein in the blood of the measured individual are easily affected by their own background noise such as physiology and psychology because the measured individual is a living body, making it difficult to extract weak signals under the interference of large background noise. The above results in low detection accuracy
