[0002] Blood sugar is a key medical indicator in the detection, diagnosis and treatment of diabetes. Clinically, blood sugar concentration is often tested to determine the dose of insulin that a patient needs to inject, thereby effectively regulating glucose metabolism, preventing the deterioration of diabetes, and reducing the occurrence of complications. Therefore, monitoring blood sugar levels is a necessary means of diagnosing and treating diabetes.

[0003] When the glucose concentration in the blood changes, the light reflection characteristics in the skin tissue will also change. A blood glucose bracelet is a non-invasive blood glucose measurement device that uses this change to infer blood glucose levels, such as a new type of blood glucose bracelet disclosed in the utility model patent with announcement number CN215191493U and a blood glucose bracelet disclosed in the appearance patent with announcement number CN304987584S. The accuracy of blood glucose bracelets is one of the issues that people are most concerned about. However, the accuracy of existing blood glucose bracelets is often different from that of traditional blood glucose meters, which needs to be solved urgently. [Utility Model Content]
