The invention discloses a multi-technology fusion non-invasive blood sugar detection device and a measurement method. The device combines near-infrared spectrum non-invasive blood sugar detection technology and optical rotation non-invasive blood sugar detection technology, improves detection sensitivity and accuracy, and suppresses human background and individual Due to the influence of differences, AOTF can be used to achieve tunable light splitting and the outgoing light is two beams of orthogonal linearly polarized light. Combining the two methods in hardware has the advantages of simple structure, strong anti-interference ability and low cost. The random forest algorithm and data fusion algorithm are used to combine the two methods in software, which effectively improves the prediction accuracy of non-invasive blood glucose concentration, and can achieve the purpose of high-precision non-invasive blood glucose concentration detection, which is suitable for the field of blood glucose detection.
Description
technical field [0001] The invention relates to the field of human blood sugar detection, in particular to a high-precision non-invasive blood sugar detection device and a measurement method. Background technique [0002] Regular and continuous blood glucose testing is of great value in understanding the blood sugar changes of diabetic patients, helping doctors determine the best treatment plan, using drugs accurately, and delaying the development of the disease. The conventional method of blood sugar detection is mainly to draw blood samples from the hospital for analysis or to use acupuncture to prick the finger, and test it through test strips. These methods all need to pierce the skin, and frequent blood collection not only causes psychological fear in patients, but also easily causes infection. At the same time, the detection cost is high, and continuous blood glucose monitoring cannot be achieved. [0003] At present, non-invasive blood glucose detection technologies ...
