Description
Technical Field
The invention relates to a blood sugar detection technology, in particular to a method for judging the accuracy of non-invasive blood sugar detection.
Background
Diabetes mellitus is a common metabolic endocrine disease, is mainly characterized by hyperglycemia, has a remarkably rising trend in recent years, and is currently suffered by about 10 percent of adults all over the world. By 2019, about 4.63 hundred million diabetics exist in 20-79 years old worldwide, wherein the number of Chinese diabetics is the first rank, and the total number of Chinese diabetics is about 1.164 hundred million. The current treatment mode of the diabetes patient is mainly to regulate and control the glucose metabolism in the body of the patient, and the dosage is determined according to the glucose content in the blood of the patient in the clinical treatment, so that the blood glucose monitoring is very important for tracking and evaluating the control and curative effect of the diabetes.
The most direct and accurate method for detecting the blood sugar value at present is a method for detecting collected venous blood, namely a biochemical analyzer is used for analysis, which is the currently accepted 'gold standard' for measuring the blood sugar concentration, but the method has strong operation expertise and high cost, and brings pain and inconvenience to patients. The second type is a invasive blood glucose meter, which uses a blood sampling pen to prick a finger to collect fingertip blood, drops the blood into test paper, and then puts the test paper into a detection instrument to obtain blood glucose data. The pricking can cause the pain of the testee, and the test paper needs to be replaced every time of measurement; the measurement cost is high, the steps are complicated, and the operation is inconvenient in multiple links such as needle insertion, blood sampling and measurement. The third category is noninvasive blood glucose meters which are always considered as the blood glucose detection eosins, a large number of noninvasive blood glucose measurement methods have been researched in recent thirty years, but no method is approved by the national drug administration for production and application, the main reason is that the system accuracy and the measurement repeatability are not good, because the existing noninvasive glucometer adopts the spectrum detection or other photoelectric induction modes for detection, because the type selection of the sensor, the interference signal are complex and various, and the difference of various human bodies is too large, no method reaches the practical level so far, but the method is still a worthy direction, compared with the traditional glucose analyzer and the traditional glucometer which adopt a biological enzyme reaction method to obtain the content of the glucose in the blood, the system accuracy and the measurement repeatability are also obtained by repeatedly detecting samples with different concentrations prepared from collected whole blood samples by an enzyme reaction method for multiple times and obtaining accuracy and stability numerical values through statistical analysis.
In the current noninvasive blood glucose detection process, whether an algorithm and hardware have problems is judged, detection data of system accuracy and measurement repeatability of the noninvasive blood glucose meter needs to be provided, and a human body cannot be used as a data source at the moment, so that the detection methods of the system accuracy and the measurement repeatability of the noninvasive blood glucose meter are different from manufacturers at the moment, and because the detection methods are different, whether detection results have referential meanings are different, so that the noninvasive blood glucose meter does not have more accurate evaluation basis on the use effect.
