The invention discloses an infrared-light non-invasive blood glucose measurement device based on a PCA (principal component analysis)-NARX (nonlinear autoregressive exogenous model) correction algorithm. An external parameter acquisition device acquires external parameters; a finger clip device can be fixed on a detected finger for non-invasive blood glucose measurement of a detected person; a laser source emits first near-infrared light and second near-infrared light to the detected finger at different moments; a first photoelectric detector and a second photoelectric detector are mounted onthe finger clip device; an application for generating blood glucose information of the detected person is stored in a memory. Blood glucose measurement accuracy is improved by comprehensively considering the following conditions: a nonlinear relation is to be contained between blood glucose concentration and near-infrared absorbance of blood glucose, human blood glucose concentration has certain fluctuation pattern with time change, external factors can affect near-infrared non-invasive blood glucose measurement, and the like.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to an infrared light non-invasive blood sugar detection device based on a PCA-NARX correction algorithm. Background technique [0002] Diabetes is a common endocrine disease worldwide. According to the Global Diabetes Status Research Report (2016 Edition), the number of diabetic patients worldwide exceeds 400 million, and diabetes has become one of the most serious public health problems in the world. The number of diabetic patients in my country is as high as 150 million, which is the largest country with diabetes, and it is showing an increasing trend and a younger trend. Therefore, the prevention and treatment of diabetes has very positive significance. At present, the commonly used blood sugar detection method is to take blood samples from the patient's fingertips. Although this method has greatly improved the level of care for diabetic patients, it also has some disa...
