Abstract

There is provided a mobile blood-sugar level measuring system enabling a diabetic patient to accurately and easily perform management of blood-sugar level measurement timing, management of changes in blood-sugar level, and further prediction of a future blood-sugar level. The blood-sugar level measuring system is formed by using a blood-sugar level processing device including a data-arithmetic-processing unit for arithmetically processing the measurement-data, an external data importing unit for entering and accumulating external data on blood-sugar level, a display device for displaying the result of the arithmetic-processing, and a display device control unit for controlling the display device, in combination with a conventional, mobile blood-sugar level monitoring device.

a measurement-data accumulation unit for accumulating measured blood-sugar level as measurement-data,

a measurement-control data-pre-processing unit for pre-processing said measurement-data,

a first display device for displaying the pre-processing result,

a first display-device control-unit for controlling said first display device,

a time-management unit for managing measurement timing of said blood-sugar level,

a control switch for controlling said monitoring unit, said measurement-data accumulation unit, said measurement-data pre-processing unit, said first display device, said first display-device control-unit, and said time-management unit, and

a first interface unit; and

a blood-sugar level processing device including

a data-arithmetic-processing unit for arithmetically processing the measurement-data from said measurement-control data-pre-processing unit or external data,

a second display device for displaying the result of the arithmetic-processing,

a second display-device control-unit for controlling the second display device, and

a second interface unit;

wherein said blood-sugar monitoring device and said blood-sugar level processing device are connectible via said first interface unit and said second interface unit, and transmit to and receive from each other at least one of said measurement-data, the result of the pre-processing, and the result of the arithmetic-processing.

2. The blood-sugar level measuring system in accordance with claim 1, wherein said data-arithmetic-processing unit has a means for creating a graph in which the measured blood-sugar level is plotted against time based on said measurement-data, and said second display device has a means for displaying said graph.

3. The blood-sugar level measuring system in accordance with claim 1 or 2, wherein said data-arithmetic-processing unit is provided with a means for creating a graph in which said measured blood-sugar level is plotted against elapsed time from immediately after a start of a breakfast, lunch, or dinner intake based on said measurement-data;

and said second display device is provided with a means for displaying said graph.

4. The blood-sugar level measuring system in accordance with claim 2 or 3, wherein said data-arithmetic-Processing unit is provided with a period-changing means for changing a period of said time by said control switch.

5. The blood-sugar level measuring system in accordance with any of claims 1 to 4, wherein said measurement-data accumulation unit is provided with a means for changing the accumulation period of said measurement-data.

6. The blood-sugar level measuring system in accordance with any of claims 1 to 5, wherein said external data is a target blood-sugar level set by a medical doctor.

7. The blood-sugar level measuring system in accordance with claim 6, wherein said second display device is provided with a means for plotting said target blood-sugar level on said graph in cooperation with said data-arithmetic-processing unit.

8. The blood-sugar level measuring system in accordance with any of claims 1 to 7, wherein said data-arithmetic-processing unit is provided with a means for creating a smoothed blood-sugar spline curve in which said measured blood-sugar level is plotted against time based on said measurement-data;

and said second display device is provided with a means for displaying said smoothed blood-sugar spline curare on said graph.

9. The blood-sugar level measuring system in accordance with any of claims 1 to 8, wherein said data-arithmetic-processing unit is provided with a means for creating a target blood-sugar response curve showing a target blood-sugar level against time by assigning said measurement-data in a higher order approximation function;
