Blood glucose detection device and detection method thereof

The invention discloses a blood glucose detection device. Collection cavities are formed in an upper clamping seat and a lower clamping seat; the collecting cavity comprises a collecting cavity inner top surface arranged on the upper clamping seat and a collecting cavity inner bottom surface arranged on the lower clamping seat; a first light source and a second light source are arranged on the top surface in the collection cavity; and a first receiver and a second receiver which respectively correspond to the first light source and the second light source are arranged on the inner bottom surface of the collecting cavity. By the adoption of the technical scheme, noninvasive blood glucose measurement can be achieved, the detection efficiency is improved, the infection risk and patient pain are reduced, and use and carrying are convenient; the device is comfortable to use, is less affected by the environment, and prevents the measurement result from being affected by different finger placement positions of a use
