Embodiment Construction

[0013] figure 1 is a block diagram of the non-invasive blood glucose monitor of the present invention. Such as figure 1 As shown, the monitoring instrument of the present invention includes a power supply 1-4, and the power supply has two electrodes A and B, and realizes reverse iontophoresis by applying a voltage to the skin 1-9 with the power supply 1-4. After a certain voltage is applied and a certain current is generated, ions will permeate from the skin surface, and the glucose molecules in the permeated ions are absorbed by the gel disc, which contains glucose oxidase, and the glucose molecules are absorbed by the glucose oxidase (glucose oxidase). Oxidase) oxidation, into gluconic acid (glucose acid) and hydrogen peroxide, namely

Abstract

A gegenionic electromosis equipment with a single-chip microprocessor for continuously monitoring blood sugar at intervals of 20 min for 12 hr without incision is disclosed. Its monitoring method includes such steps as penetrating a very-low current through skin to sample the glucose on a gel tray containing the glucose oxidase, inverting the glucose to hydrogen peroxide by said glucose, oxidase, detecting the hydrogen peroxide by a biosensor to generate an electric signal, and determining the concentration of blood sugar according to the signal intensity which is proportional with the concentration of blood sugar. Its advantages are high correctness and automation level, no pain and simple operation.

Description

technical field [0001] The present invention relates to a non-invasive blood sugar monitoring method and its device, in particular to a non-invasive blood sugar monitoring method and device using reverse iontophoresis technology Background technique [0002] The "Diabetes Control and Complications Trial" (DCCT) and the UK Prospective Diabetes Study (UKPDS) conducted in the United States and Canada in recent years have shown that regardless of type 1 or type 2 diabetes, good blood sugar control can reduce diabetic retinopathy. , kidney and neuropathy; at the same time, there is also a tendency to decrease in large vessel diseases, such as myocardial infarction, angina pectoris, stroke or peripheral vascular disease. In the United States, complications caused by poor blood sugar control cost about 100 billion medical expenses each year. Therefore, the American Diabetes Association (ADA) recommends that blood sugar be controlled at 80-120mg / dl before meals and 100-140mg / dl befo...
