Description

technical field [0001] The invention relates to the field of blood glucose meters, in particular to a multi-spectrum transceiver integrated sensor and a non-contact non-destructive blood glucose meter. Background technique [0002] The use of a non-contact blood glucose meter can avoid the risk of the person under test being infected by bacteria or viruses and the risk of cross-infection among the people being tested by traditional blood glucose meters using finger blood collection or skin collection to detect blood sugar. The non-contact non-destructive blood glucose meter is a new type of blood glucose meter that does not directly contact the skin or cause damage to the skin surface. The working principle of non-contact nondestructive blood glucose meter is to use optical means to characterize the change of blood sugar concentration by detecting the change of absorption intensity of sugar molecules in blood to light of special wavelength. It has the characteristics of simp...
