FIG. 5 is a conceptual diagram showing an application state of the smart blood glucose meter 100 according to another embodiment of the present invention

The smart blood sugar self-meter relating to the present invention can use the blood glucose measurement principle as shown in the following formula.

(1) Glucose + GOx-FAD? Gluconic acid + GOx-FADH2

(2) GOx-FADH2 + electron transfer mediator (oxidation state) → GOx-FAD + electron transfer mediator (reduction state)

Wherein GOx is glucose oxidase and GOX-FAD and GOX-FADH2 represent oxidation state and reduction state of FAD (flavin adenine dinucleotide), which is an active site of glucose oxidase, respectively.

As shown in Reaction Scheme (1), (1) glucose in the blood is first oxidized to gluconic acid by the catalytic action of the glucose oxidase. At this time, FAD which is an active site of glucose oxidase is reduced to FADH2. (2) Thereafter, the reduced FADH2 is oxidized to FAD through an oxidation-reduction reaction with the electron transfer mediator, and the electron transfer mediator is reduced. The electron transport medium thus formed is diffused to the surface of the electrode. At this time, the concentration of the glucose is measured by measuring the current generated by applying the oxidation potential of the reduced electron transport medium on the working electrode surface.

According to the above measurement principle, the configuration of the smart self-glucose meter is composed of an electrode called a strip, a converter (analog digital converter) circuit for reading the current value and the ambient temperature of the electrode into a digital signal, a current value and a temperature value of the read electrode And a microcomputer for calculating blood glucose values using the blood glucose meter. The microcomputer includes a user input unit for reading a user command, a display for displaying a value, a memory for storing a value, a communication unit for transmitting a value to a remote place such as a PC, and a clock unit for performing a timer function. Since the microcomputer has to perform various functions, the higher the performance, the easier to implement the function. The structure of the existing self-glucose meter is structurally complicated to implement various functions. The communication section is limited to a system equipped with a general-purpose OS such as Windows and Linux, or a system with a hardware serial port, so that the communication section can communicate with a smartphone equipped with a serial port like an iPhone. However, Such as smart phones, can not communicate with devices that do not support serial communication. In order to use a component with USB to Serial function to communicate serial communication with Android-based smart phone, you have to install Rooting (super user right) and install USB to Serial driver.
