Blood sugar non-invasive detection instrument based on near infrared spectrum analysis and realization method thereof

Abstract

The invention discloses a blood sugar non-invasive detection instrument based on near infrared spectrum analysis and a realization method thereof. The detection instrument comprises a casing, an intelligent processor, a semiconductor laser module, an optical fiber coupler, a beam splitter, a flange, a signal processing circuit, a detection probe and a display, and is characterized in that the intelligent processor comprises an analog-to-digital conversion module, a CPU (central processing unit), a filtering module, a memory, a power supply module and a communication module; the detection instrument realizes non-invasive detection and analysis on the human body blood sugar on the basis of the human body blood sugar information obtained through near infrared spectrum analysis by using diffused reflection signals after two kinds of light sources are irradiated to the human body limb positions through the detection probe. The blood sugar non-invasive detection instrument has the beneficial effects that the structure of a light path transmission system is reasonable; the multi-time measurement is performed on the basis of the near infrared spectrum analysis; the average value is taken to reduce errors; the blood sugar non-invasive detection can be conveniently realized; the blood sugar information of a detected person can be stored; the blood sugar concentration change condition of the detected person can conveniently realize health management; the diagnosis and the treatment can be better performed.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a non-invasive blood glucose detector based on near-infrared spectrum analysis and an implementation method thereof. Background technique [0002] Diabetes is a worldwide epidemic disease. According to the World Health Organization (WHO) estimates, there are currently 180 million people worldwide suffering from diabetes, and this number will more than double by 2030. [0003] There are more than 100 million people with diabetes in my country, which has become the country with the largest number of people with diabetes in the world, and the pre-diabetic population is as high as 50.1%. Among people with diabetes, only 30.1% were previously diagnosed, 25.8% were treated, and only 39.7% of treated patients were controlled. Therefore, the large number of diabetic patients in my country, the prevalence of diagnosis and treatment is far from enough, and the remission rate of...
