Blood-sampling-free type blood sugar monitoring device and use method thereof

Abstract

The invention relates to the field of medical instruments, in particular to a blood-sampling-free type blood sugar monitoring device and a use method of the blood-sampling-free type blood sugar monitoring device. The blood-sampling-free type blood sugar monitoring device comprises a host and a PCB arranged in the host. The PCB is provided with an LCD display screen, a microprocessor, a blood sugar detection circuit, a storage module and a power module, wherein the blood sugar detection circuit, the storage module and the power module are electrically connected with the microprocessor. The blood sugar detection circuit comprises a blood sugar detection module. The PCB is further provided with a human body resistance collecting circuit electrically connected with the microprocessor. The human body resistance collecting circuit comprises a human body resistance collecting module used for detecting the value of resistance between two points of the human skin, and converting a detection result to a blood sugar value through the microprocessor to be displayed on the LCD display screen of the host. The human body blood sugar changes are reflected by testing skin resistance, a traditional mode that blood sampling is needed every time a blood sugar test is carried out is omitted, pains of patients are relieved, and the blood sugar changes can be conveniently mastered in time.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a blood-sampling-free blood glucose monitoring device and a method for using the same. technical background [0002] Blood sugar level is a very important indicator for diabetes, so many diabetics are very concerned about it. In fact, when diagnosing diabetes, it is judged from two aspects: fasting blood sugar level and two-hour blood sugar level after meals. Normal fasting blood glucose: The normal range of fasting blood glucose is 3.9-6.1mmol / L (70-110mg / dL), if it is higher than 7.0mmol / L (126mg / dL), it is diagnosed as diabetes. Then the diagnostic standard of fasting diabetes is 7.0mmol or 126 mg. You can see that there is a gap between the normal value and the fasting diagnosis of diabetes. Some people are neither normal nor diabetic. We call this symptom increased fasting blood sugar (impaired). Normal postprandial blood glucose level: The normal two-hour postprandial bloo...

Problems solved by technology

[0006] 2. Susceptible to interference

[0007] 3. Affected by the test conditions, temperature, humidity and altitude will affect the test results of the blood glucose meter

[0009] Since it involves blood collection to detect blood sugar levels, in addition to testing in hospitals, various factors such as the environment, professional knowledge, and operating proficiency of household detectors will cause large errors in monitoring results. Therefore, it is necessary to develop A blood glucose meter that can monitor the change of blood sugar in real time without blood collection, so that patients can monitor the change of blood sugar more conveniently anytime and anywhere, so as to adjust their living habits and diet in time
