Abstract

The invention discloses a blood glucose detection method and device. The blood glucose detection device containing an antenna array is used for conducting blood glucose detection. The antenna array comprises a plurality of transmitting antenna array units and a plurality of receiving antenna array units. The method includes the steps that multiple paths of microwave detection signals of different frequencies are sent to conduct blood glucose detection; multiple paths of microwave reflection signals corresponding to the multiple paths of microwave detection signals are received; the multiple paths of microwave detection signals and the multiple paths of microwave reflection signals are analyzed, and a reflection spectrum of the multiple paths of microwave detection signals of different frequencies is obtained; the reflection spectrum of the multiple paths of microwave detection signals of different frequencies is analyzed, and the blood glucose concentration is determined. By means of the blood glucose detection method and device, the influence, on the microwave impedance magnitude, of the microwave frequency in the blood glucose detection process can be avoided, and thus the accuracy of microwave blood glucose detection is guaranteed; the reflection spectrum of the multiple paths of microwave detection signals of different frequencies is analyzed, and microwave blood glucose detection is achieved.

Description

technical field [0001] The invention relates to the field of blood sugar detection, in particular to a blood sugar detection method and device. Background technique [0002] With the development of science and technology, in the field of blood glucose detection, compared with other non-invasive blood glucose detection schemes, microwave noninvasive blood glucose detection scheme has the advantage of fast detection speed, and the basic principle of its realization of blood glucose detection is: when the microwave passes through the blood glucose solution Ions (especially sodium ions) in the blood glucose solution can affect the intended path of the microwaves. That is, the ions in the blood sugar solution present some resistance to the microwaves, reducing their amplitude and causing them to phase shift. The magnitude of this impedance is influenced by surrounding glucose molecules and varies with blood glucose concentration. [0003] Therefore, when using microwaves for no...
