Non-invasive blood glucose meter

Abstract

The invention relates to a non-invasive blood glucose measuring device comprising: a measuring module comprising: a light source configured to illuminate with a combined wavelength onto the finger of the subject to be measured; and a signal receiver for detecting and receiving the radiation signal transmitted through or reflected from the finger of the subject to be measured; and a controller electrically connected to and receiving the measurement result signal from the measuring module, which includes a microprocessor linked to a data storage unit; wherein the microprocessor is configured to control the light source to emit light with a single wavelength or combined wavelength; analyze and calculate the blood glucose concentration of the subject to be measured; and display the measurement result through a display device.
