Description

Glucose measuring device {GLUCOSE MEASURING DEVICE}

The present invention relates to a glucose measuring device, and more particularly, to a glucose measuring device that irradiates a light beam to a user's finger to measure glucose.

In general, measuring and managing the concentration of blood glucose is essential to manage diabetes, which is one of the chronic diseases of modern people.

There are two main ways to continuously manage blood sugar. It can be divided into a method of using a self-measurement system and a system that monitors blood sugar by attaching it to a specific part of the body.

The self-measurement system is portable and can manage diabetes by classifying and checking blood sugar that changes daily before/after meals using a measuring instrument and disposable test strips.

In the case of using the self-measurement system, it is possible to measure using a small amount of blood from the fingertip or replacement site using a blood sampling tool on a regular basis every day.

Accordingly, the basic measurement principle will be described. When an oxidase that breaks down glucose in blood breaks down glucose, hydrogen peroxide is generated, and when a constant voltage is applied to decompose it at the electrode, it is decomposed. At this time, the generated electrons appear as the intensity of a certain amount of current at the electrode through the electron transport medium. And since the generated current is proportional to the concentration of glucose in the blood, the blood glucose level can be quantified.
