Noninvasive blood glucose detection device

Abstract

The invention relates to a noninvasive blood glucose detection device. The device comprises a microwave cavity, a voltage system, a temperature and moisture signal processing module, a signal demodulation processing module, a microcontroller, a display system module, a warning system module, a memory and a calibration reset module; the microcontroller module analyzes and processes temperature andmoisture blood glucose signals and demodulation signals to generate a blood glucose concentration value and compares the generated blood glucose concentration value with a normal value of the blood glucose concentration in the memory; the device can conduct continuous, noninvasive and accurate blood glucose detection on patients.

Description

technical field [0001] The invention relates to the field of medical testing, in particular to a microwave-based non-invasive blood sugar testing device Background technique [0002] Diabetes is a common chronic systemic metabolic disease with a relatively high incidence and has become the second largest killer in the world after cancer. According to the statistics of the World Health Organization, my country has become the second largest country in the number of diabetic patients. Long-term diabetic patients are prone to complications such as cardiovascular and cerebrovascular diseases, kidney failure, blindness, heart disease, stroke, and high blood pressure, which seriously endanger human health. At present, there is no effective method to completely cure diabetes. The blood sugar concentration of the human body will change with factors such as diet and exercise. Therefore, effective control of diet, exercise, and insulin injections are used to achieve the purpose of co...

AI Technical Summary

Problems solved by technology

At present, diabetic patients usually go to the hospital or self-test at home, and the methods used are generally invasive testing, that is, more accurate biochemical enzyme detection through blood sampling through the vein, or colorimetric measurement with test paper after blood sampling from fingertips , these methods usually consume a lot of biochemical reagents, take a long time to detect, and take too many samples, which brings unavoidable pain and inconvenience to patients.

In addition, this method only provides an instantaneous value of blood glucose concentration, which may change rapidly during the detection period, which is not ideal for the detection of diabetes and the prevention of complications

At the same time, this invasive detection method will cause long-term damage to the patient's skin and is also prone to infection
