Abstract

The invention discloses a noninvasive blood glucose detector and detection method based on multi-source information sensing and fusion. The detector is based on a near-infrared photoelectric detectiontechnology, corrects the interference of a measurement environment on blood glucose photoelectric response information by synchronously acquiring the temperature of a detection part and the pressureinformation of the detection part relative to a probe, and thus achieves noninvasive, rapid and high-precision detection. The invention further provides a noninvasive blood glucose detection method based on multi-source information sensing and fusion; the method utilizes a blood glucose value of invasive detection measured at the same time and a measurement value of the noninvasive blood glucose detector, a blood glucose prediction model and a data sample set individualized for a user are established, the influence of the characteristics of the user on the detection precision is eliminated, and finally, the purpose of improving the detection precision and stability is achieved.

Description

technical field [0001] The invention belongs to the field of human blood glucose detection, and in particular relates to a non-invasive blood glucose detector and detection method based on multi-source information perception and fusion. Background technique [0002] Regular and continuous blood sugar testing is of great value in understanding blood sugar changes in diabetic patients, helping doctors determine the best treatment plan, using drugs accurately, and delaying the development of the disease. The routine detection method of blood sugar is mainly to draw blood sample through the hospital to analyze or utilize the mode of acupuncture finger, detect through the test paper. These methods all need to puncture the skin, and frequent blood collection not only creates psychological fear in patients, but also easily causes infection. At the same time, the detection cost is high, and continuous blood sugar monitoring cannot be realized. [0003] Non-invasive blood sugar dete...
