NFC-based continuous blood glucose testing instrument and testing method

Abstract

The invention belongs to the field of medical monitoring equipment and discloses a NFC-based continuous blood glucose testing instrument and a testing method. The NFC-based continuous blood glucose testing instrument comprises a blood glucose acquisition front end, and the blood glucose acquisition front end comprises an enzyme chemical biosensor, a constant-potential circuit, a signal processingcircuit, a microprocessor and NFC tags. An output end of the enzyme chemical biosensor is electrically connected with the microprocessor through the signal processing circuit, the constant-potential circuit is electrically connected with an input end of the enzyme chemical biosensor, and the NFC tags are integrated in the microprocessor. The NFC-based continuous blood glucose testing instrument and the testing method have advantages that on the one hand, advantages on the basis of the blood glucose testing method are realized, fast connection is realized, low power consumption is kept constantly in operation, and accordingly cost saving is realized; on the other hand, long-term measurement storage is realized, patients or monitoring personnel can check monitoring data at any time to timelyknow health conditions of the patients and realize effective blood glucose control.

Description

technical field [0001] The invention relates to an NFC-based continuous blood glucose detector and a detection method, which belong to the field of medical monitoring equipment. Background technique [0002] According to the latest eighth edition of Diabetes Map, the report shows that as of 2017, about 425 million adults around the world suffer from diabetes, accounting for 8.8% of the total population. It is estimated that by 2045, the number of diabetic patients may reach 629 million. The treatment of diabetes is mainly to monitor the glucose metabolism in the patient's body. The doctor gives the treatment method and daily routine according to the glucose content in the blood, so that the blood sugar can be effectively controlled. [0003] In the past, clinical blood glucose monitoring methods were usually invasive monitoring, the operation process was cumbersome, and professional medical staff were required to read the data. Therefore, a non-invasive blood glucose monito...

AI Technical Summary

Problems solved by technology

The dynamic continuous blood glucose monitoring system based on body fluids can only have a certain accuracy after the plasma glucose diffuses into the interstitial fluid and reaches an equilibrium state, and the concentration of blood glucose and tissue serous glucose is not much different. The blood glucose monitoring value is (38±15)% lower than the blood-based blood glucose measurement value, which will exaggerate the hypoglycemia of liquid monitoring and cause the influence of false blood glucose value accuracy
