Noninvasive blood glucose detector and blood glucose detection method thereof

Abstract

The invention discloses a noninvasive blood glucose detector and a blood glucose detection method thereof. The blood glucose detector comprises an electrochemical detection sensor, an excitation circuit, a constant potential circuit, a transimpedance amplification circuit, an FIFO memory and a central processing unit; and the electrochemical detection sensor is connected with the transimpedance amplification circuit, the electrochemical detection sensor is respectively connected with the input end of the constant potential circuit and the input end of the excitation circuit, the output end of the constant potential circuit is connected with the input end of the FIFO memory through the first AD converter, the transimpedance amplification circuit is connected with the FIFO memory through the second AD converter, the FIFO memory is connected with the central processing unit, the feedback output end of the central processing unit is connected with the excitation circuit through the DA converter, and the excitation circuit is connected with the electrochemical detection sensor end. The glucose content in blood glucose is converted by measuring the glucose content in saliva, noninvasive blood glucose detection is achieved, the detection error is small, the circuit performance is stable, and the threshold and risk of blood glucose detection can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of biomedical detection, and in particular relates to a non-invasive blood sugar detector and a blood sugar detection method thereof. Background technique [0002] At present, the number of people suffering from diabetes in my country exceeds 100 million, and the number of deaths due to diabetes is as high as one million people every year. Since the current medical level has not completely cured diabetes, how to detect blood sugar concentration to remind patients to use hypoglycemic drugs has become a major means. With the continuous development of technology, the new electronic blood glucose detector has been able to solve most of the problems of blood glucose measurement. The traditional blood glucose detector needs to collect blood samples frequently, and the needle sampling process is traumatic and painful. Long-term testing can easily lead to complications caused by diabetes, and bring great pain and s...
