Abstract

The invention discloses a dynamic photoacoustic characteristic spectrum nondestructive glucometer based on a nano marker and a preparation method of the nano marker, which relates to the technical field of blood glucose measuring instruments, the glucometer comprises a laser, a laser modulator, a microprocessor, a display module, a piezoelectric transducer array and a pre-amplifier, and further comprises an interstitial fluid adsorption device, a buffer reaction vessel and a nano marker box, the photoacoustic conversion efficiency is remarkably improved by using the nano marker, photoacousticsignals are enhanced, meanwhile, blood glucose detection is more direct by connecting the nano marker with blood glucose protein, and the influence of other tissue components is avoided.

Description

technical field [0001] The invention relates to the technical field of blood glucose measuring instruments, in particular to a non-destructive blood glucose meter based on a nanomarker-based dynamic photoacoustic characteristic spectrum and a preparation method of the nanomarker. Background technique [0002] Diabetes is a metabolic disease characterized by chronic hyperglycemia caused by various etiologies, accompanied by a series of metabolic disorders of sugar, protein, fat, water and electrolytes in the body caused by insulin secretion or insulin action defects. The implementation of blood sugar monitoring can better control the blood sugar changes of diabetic patients. It has important guiding significance for life rules, activities, exercise, diet and rational drug use. A blood glucose meter is an electronic instrument for measuring blood sugar levels. [0003] Noninvasive, continuously measurable, and portable continuous blood glucose detectors have become the current...
