Problems solved by technology
Acupuncture will cause pain to the subject, and secondly, the test paper needs to be replaced for each measurement; resulting in high cost of measurement and cumbersome steps, and inconvenient operation due to multiple links such as acupuncture, blood collection, and measurement
The third category is non-invasive blood glucose meters. Non-invasive blood glucose meters have always been considered the dawn of blood glucose detection. The current non-invasive blood glucose meters use spectral detection or other photoelectric sensing methods for detection, but the signal interference caused by environmental factors, the accuracy of the measurement site setting , as well as the portability and ease of use of the blood glucose meter itself, all limit its real use

The invention relates to a noninvasive glucometer which comprises a noninvasive glucometer body, a signal collecting and processing unit and a power management unit. The noninvasive glucometer body comprises a shell and a detection part; the detection part is arranged on the shell and is used for accommodating an organism to be detected; the power management unit is arranged in the shell and is used for supplying power to the signal acquisition and processing unit; the signal collecting and processing unit is arranged in the shell and used for detecting and processing physical sign parameters and environment characteristic parameters of a detected organism and generating and outputting blood glucose detection result data. Wherein the physical sign parameters comprise a pulse photoplethysmography (PPG) signal of the measured living body, a contact conduction temperature of the measured living body and a thermal radiation temperature of the measured living body; the environment characteristic parameters comprise the temperature and the humidity around the measured living body and the temperature and the humidity of the environment where the noninvasive glucometer is located.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a non-invasive blood glucose meter. Background technique [0002] Diabetes is a common metabolic endocrine disease characterized by hyperglycemia. In recent years, its incidence has shown a significant upward trend. Currently, about 10% of adults in the world suffer from this disease. As of 2019, there are about 463 million diabetics among people aged 20 to 79 in the world, among which the number of diabetic patients in China ranks first, with a total of about 116.4 million people. [0003] The current treatment method for diabetic patients is mainly to regulate the glucose metabolism in the patient's body. The important basis in clinical treatment is to determine the dosage of the drug through the level of glucose content in the patient's blood. Therefore, blood glucose monitoring is very important for tracking and evaluating the control and curative effect of diabetes...
