Problems solved by technology

[0003] The traditional blood sugar detection method is invasive blood test, which is not conducive to continuous detection, but also has the risk of infection of other diseases during the detection process
For this reason, those skilled in the art have proposed a non-invasive blood glucose detection method, typical methods include: near-infrared spectroscopy, mid-to-far infrared spectroscopy, Raman spectroscopy, photoacoustic spectroscopy, light scattering, polarized light rotation, radio frequency impedance method, metabolic heat combination method and subcutaneous interstitial fluid or saliva enzyme method, etc., the algorithm of the above detection methods is complicated, and the detection sensitivity is low

Embodiment ( 1

[0033] see figure 1 A schematic flowchart of an embodiment of a non-invasive blood glucose detection method of the present invention is shown. Depend on figure 1 It can be seen that the method comprises the following steps:

[0034] Step 101: Determine the auricular points to be tested, and the auricular points include: eye points, inner ear points, tongue points or forehead points.

[0035] Based on the neurovascular coupling mechanism, auricular points have a reflex relationship with the corresponding human body areas. The eye points, inner ear points, tongue points, and forehead points are selected respectively, which not only takes into account the measurement sensitivity of blood sugar indicators of the organs involved, but also considers the light transmittance of the earlobe. better sake.

[0036] Step 102: According to the near-infrared transmission voltage signal of the auricular point to be measured obtained by the near-infrared modulation signal receiving-transmi...

[0047] see figure 2 A schematic structural diagram of another embodiment of a non-invasive blood glucose detection method of the present invention is shown. Depend on figure 2 As can be seen, this embodiment includes:

[0048] Step 101: Determine the auricular points to be tested, and the auricular points include: eye points, inner ear points, tongue points or forehead points.

[0049] Step 102: According to the near-infrared transmission voltage signal of the auricular point to be measured obtained by the near-infrared modulation signal receiving-transmitting circuit, the reduced scattering coefficient of the auricular point tissue is extracted.

[0050] Step 103: According to the first-order response and second-order response of the reduced scattering coefficient, determine the increment of the voltage signal between adjacent preset time bases and the increase of spectral impairment between adjacent preset time bases quantity.

[0051] Step 104: According to the preset...

Abstract

The invention discloses a method for testing blood glucose in a non-invasive manner. The method includes extracting first-order response and second-order response of reduced scattering coefficients of the tissues of the auricular point of a patient according to near-infrared transmission voltage signals of the to-be-tested auricular point of the patient; determining increments of the voltage signals among adjacent preset time bases and increments of spectral subtraction values among the adjacent preset time bases, and computing the concentration of the blood glucose of the tested patient according to a preset formula. The near-infrared transmission voltage signals are acquired by a near-infrared modulation signal receiving-transmitting circuit. The method has the advantage that the concentration of the blood glucose of the tested patient can be determined by the aid of the difference between the first-order response and the second-order response of the reduced scattering coefficients of the tissues of the auricular point of the patient when concentrations of blood glucose are different, so that the testing sensitivity can be improved.

Description

technical field [0001] The invention relates to the field of biological detection, in particular to a non-invasive blood sugar detection method based on auricular point near-infrared modulation signals. Background technique [0002] Diabetes mellitus is a common metabolic endocrine disease characterized by hyperglycemia, and is a worldwide epidemic. In recent years, with the development of my country's social economy, the improvement of residents' living standards, and the acceleration of population aging, the incidence of diabetes has been increasing year by year. There is currently no effective cure for diabetes, and blood sugar control is the only treatment. Timely blood glucose detection is of great significance for controlling diabetes, preventing complications, and improving the quality of life of diabetic patients. [0003] The traditional blood sugar testing method is invasive blood testing, which is not conducive to continuous testing, but also has the risk of inf...
