7 is an exemplary diagram illustrating a blood sugar profile generated based on a general blood sugar measurement.

As shown in FIG. 7 , the blood glucose profile is obtained from the blood glucose measurement device (combustion blood glucose meter) 100 at the same time as the actual blood glucose information periodically measured through the disposable blood glucose device (disposable blood glucose meter) and the time at which the actual blood glucose information is measured. It may include blood sugar information corrected based on the skin temperature.

Specifically, the blood sugar measurement device 100 measures blood sugar at a time when actual blood sugar information is measured through a disposable blood sugar device (not shown). Also, the blood glucose measurement device 100 senses the skin temperature at the time the blood glucose value is measured. Thereafter, the blood sugar measurement device 100 corrects the pre-measured blood sugar value based on the sensed skin temperature.

Meanwhile, the skin temperature may be the external skin temperature, and the external skin temperature directly exposed to the external temperature causes a difference in the internal skin temperature according to a change in the external temperature. That is, when the external temperature is high, the outer skin temperature may be measured relatively higher than the inner skin temperature, and when the external temperature is low, the outer skin temperature may be measured relatively lower than the inner skin temperature.

For example, the disposable blood sugar device (not shown) may measure a blood sugar value between 90 and 100 mg/dL at the first time point 710 . Meanwhile, at the first point 710 , the outer skin temperature may be sensed to be low by the external temperature of the region where the user wearing the blood glucose measurement device 100 is located. In this case, the blood sugar measurement device 100 overcorrects the blood sugar value so that it can be measured higher than the blood sugar value measured through the enzyme sensor 110-1 based on the detected external skin temperature. Accordingly, the blood sugar measurement device 100 may determine the blood sugar value corrected to be between 100 and 110 mg/dL as the user blood sugar information at the first point 710 .

Accordingly, the blood sugar value determined as the user blood sugar information through the blood sugar measurement device 100 at the first point 710 has an error of about +10 mg/dL based on the blood sugar value measured by the disposable blood sugar device (not shown). will occur

In addition, a high external skin temperature may be detected at the second point 720 by the external temperature of the region where the user wearing the blood glucose measurement device 100 is located. In this case, the blood sugar measurement device 100 overcorrects the blood sugar value so that it can be measured lower than the blood sugar value measured through the enzyme sensor 110-1 based on the detected external skin temperature. Accordingly, the blood sugar measurement device 100 may determine the blood sugar value corrected to be between 90 and 100 mg/dL as the user blood sugar information at the second point 720 .

Accordingly, the blood glucose value determined as the user blood glucose information through the blood glucose measurement device 100 at the second point 720 has an error of about - 20 mg/dL based on the blood glucose value measured through the disposable blood glucose device (not shown). will occur

Accordingly, the blood sugar measurement device 100 may determine the blood sugar value corrected to be between 100 and 110 mg/dL as the user blood sugar information at the first point 810 .

Accordingly, the blood glucose value determined as the user blood glucose information through the blood glucose measurement device 100 at the first point 810 has an error of about +10 mg/dL based on the blood glucose value measured through the disposable blood glucose device (not shown). will occur

Meanwhile, the electronic device 200 according to the present invention provides an enzyme sensor 110- of the blood glucose measurement device 100 based on the external temperature sensed at the first point 810 and the skin temperature sensed from the blood glucose measurement device 100 . 1) determines the predicted temperature of the inserted inner skin. Thereafter, the electronic device 200 corrects the blood sugar information received from the blood sugar measurement device 100 based on the predicted internal skin temperature. Accordingly, the electronic device 200 may determine the blood sugar value corrected to be between 95 and 100 mg/dL as the user blood sugar information at the first point 810 .

Accordingly, the electronic device 200 according to the present invention may correct the blood sugar value measured by the disposable blood sugar device (not shown) to a blood sugar value that falls within a smaller error range than the blood sugar value corrected by the blood sugar measurement device 100 . there is.

Meanwhile, the disposable blood sugar device (not shown) may measure a blood sugar value between 110 and 120 mg/dL at the second point 820 . In addition, at the second point 820 , the outer skin temperature may be detected to be high by the external temperature of the region where the user wearing the blood glucose measurement device 100 is located. In this case, the blood sugar measurement device 100 overcorrects the blood sugar value so that it can be measured lower than the blood sugar value measured through the enzyme sensor 110-1 based on the detected external skin temperature. Accordingly, the blood sugar measurement device 100 may determine the blood sugar value corrected to be between 90 and 100 mg/dL as the user blood sugar information at the second point 820 .

Accordingly, the blood sugar value determined as the user blood sugar information through the blood sugar measurement device 100 at the second point 820 has an error of about −20 mg/dL based on the blood sugar value measured by the disposable blood sugar device (not shown). will occur

Thereafter, the blood sugar measurement device 100 transmits blood sugar information including a current value corresponding to the measured blood sugar value and skin temperature information sensed at the point in time when the blood sugar value is measured to the electronic device 200 .

When such blood glucose information and skin temperature information are received, the electronic device 200 obtains external temperature information of an area in which the user wearing the blood glucose measurement device is located ( S920 ).

Here, the predicted temperature of the outer skin is a predicted temperature based on the external temperature information and the time exposed to the external temperature, which can be calculated from the above-mentioned [Equation 2].

As a result of the comparison, if the predicted temperature of the outer skin and the skin temperature information received from the blood glucose measurement device 100 are different, the electronic device 200 sets the skin temperature information received from the blood glucose measurement device 100 to the first region of the inner skin.

The predicted temperature of the second region may be calculated from the above-mentioned [Equation 3]. Accordingly, the electronic device 200 may determine the value calculated by [Equation 3] as the predicted temperature of the second region.
