Blinks. The control device 30, blood glucose level measuring means 21, memories 23 and 25, communication means 24 and the like are provided in the main body 11.
[0014]
Next, the operation of the blood sugar level measuring apparatus 10 configured as described above will be described.
[0015]
First, personal reference data (personal reference data) for the wearer is created. This personal reference data is created by having three meals, breakfast, lunch, and dinner, and getting the appropriate energy required for the day. Then, blood glucose level data is measured at regular time intervals on the day, and this data is used as personal reference data.
[0016]
In measuring the reference data, the main body 11 is first attached to the arm by the wristband 12. With this attachment, the electrodes 13 and 14 provided on the back surface of the main body 11 come into contact with the skin of the arm. Then, the lid 15 is opened, the personal reference data creation mode is set by operating the switch S of the operation unit 19, the start switch of the operation unit 19 is pressed after breakfast or almost simultaneously with breakfast, and the lid 15 is closed.
[0017]
By the way, the appropriate energy is obtained from an individual's weight (Kg) × required energy (Kcal).
[0018]
The required energy is 25 (Kcal) mainly for people living in the room, 30 (Kcal) for those who are not working hard, and 40 (Kcal) for those who are working hard. The ratio of calorie intake is 6 in the morning, 5 in the day, and 4 in the evening.
[0019]
When the start switch of the operation unit 19 is pressed, the control device 30 operates the blood sugar level measuring means 21 every time a predetermined time elapses, and current is passed between the electrodes 13 and 14 to measure the blood sugar level. Blood glucose level obtained by the measurement (measurement values) while being stored in the memory 23, the measured value is displayed on the display unit 17. And the measurement is complete | finished after progress for a predetermined time from the peak time of the blood glucose level after having dinner.
[0020]
When the measurement is completed, the registration switch S of the operation unit 19 is pressed. Then, the data stored in the memory 23 is transferred to the memory 25, and the data transferred to the memory 25 is stored in the memory 25 as personal reference data.
[0021]
Here, one piece of data (one day's worth of data) is used as personal reference data. However, for example, data obtained by measuring three days and taking the average may be used as personal reference data. Data obtained by taking measurement data (when eating a normal meal) may be used as personal reference data. In this case as well, the measurement may be performed for several days and the average may be taken.
[0022]
When registration of personal reference data is completed, measurement will be performed from the next day. This measurement is performed by pressing the start switch of the operation unit 19. Then, the control device 30 operates the blood sugar level measuring means 21 at every elapse of a certain time, and measures the blood sugar level by causing a current to flow between the electrodes 13 and 14. The blood glucose level (measured value) obtained by this measurement is stored in the memory 23 and the measured value is displayed on the display 17. The latest blood glucose level stored in the memory 23 is displayed on the display 17.
[0023]
Based on the blood glucose level stored in the memory 23, the control device 30 creates a measurement graph G1 as shown in FIG. Further, the control device 30 creates a reference graph G 2 based on the personal reference data stored in the memory 25 and displays it on the display 20.
[0024]
In this case, the measurement starting measurement start and the reference graph of measurement graph G1 G2 are coincident, or the peak P1~P3 reference data any or all of the peaks R1~R3 measurement data for each predetermined time Displayed with matching.
[0025]
In addition, the control device 30 compares the maximum value and minimum value of the personal reference data, that is, the maximum value P1 and minimum value Q1 of the reference graph G2, with the measured value measured every certain time, and the measured value is the maximum value. When 20% or more is exceeded from P1, the warning indicator 18 blinks to indicate that the user is taking too much food or lacking exercise. When the measured value falls by 20% or more from the minimum value Q1, the warning indicator 18 blinks to warn that the blood glucose level is too low.
[0026]
When the subject opens the lid 15 of the main body 11, the latest blood sugar level displayed on the display 17 in addition to the flashing of the warning display 18, and the graphs G 1 and G 2 displayed on the display 20 It can be seen at a glance whether the measurement graph G1 is away from the reference graph G2. Also, the change in blood glucose level over time can be seen at a glance from the graph G1.
[0027]
The warning can also be configured so that it can be confirmed even when the lid 15 is not opened.
[0028]
In this way, since the personal reference data created for the individual wearer (subject) is compared with the measurement data, the wearer takes calories on the basis of a healthy daily life suitable for the individual. It is possible to know trends such as overshooting and lack of exercise, and to properly detect abnormalities. That is, it is possible to easily recognize that the blood glucose level measured in consideration of the life rhythm of the subject is an abnormal value or a value close to abnormal.
[0029]
In the above embodiment, the maximum and minimum values of the personal reference data are compared with the measured value, and the warning indicator 18 is blinked when the measured value exceeds 20% from the maximum value P1, but the measured data The maximum values R1 to R3 for each peak and the maximum values P1 to P3 for each peak of the personal reference data are compared, and the difference (R1-P1, R2-P2, R3-P3) exceeds the specified value In such a case, the warning indicator 18 may be blinked to notify the user that he / she is taking too much food or is exercising.
[0030]
In addition, a meal time serving as a reference time is input by operating the switch S of the operation unit 19, and when a predetermined time has elapsed from this meal time, the control device 30 operates the blood sugar level measuring means 21 to measure the blood sugar level. The measured blood glucose level is compared with the reference blood glucose level of the personal reference data that has passed a predetermined time from the meal time. When the measured blood glucose level exceeds the reference blood glucose level by a predetermined value or more, the warning indicator 18 May be blinked.
[0031]
Thus, measuring the blood glucose level when a predetermined time has elapsed from the meal time has the following advantages.
[0032]
While it is known that blood glucose levels rise for about an hour after meals and then gradually decline, people who are not diabetic but are generally called diabetic reserves will experience a decrease in blood glucose levels after meals. Is also known to be slow. Therefore, by measuring the blood glucose level after a predetermined time, for example, about 2 hours from the meal time, it becomes easy to recognize whether or not the subject is close to diabetes.
[0033]
In order to transfer the data stored in the memory 23 to, for example, a mobile phone, the main body 11 and the mobile phone are connected with a code (not shown). When the operation switch S is operated, the data stored in the memory 23 is read, and this data is transferred to the mobile phone by the communication means 24. The data transferred to the mobile phone can be transmitted to the hospital, for example, by the mobile phone. By this transmission, the doctor can grasp the temporal change of the blood glucose level without going to the hospital and can receive appropriate advice from the doctor.
[0034]
As described above, since the body 11 is simply worn on the wrist by the wristband 12, a current flows between the electrodes 13 and 14 every time set, and the blood sugar level is automatically measured. Therefore, there is no need to collect blood from the patient, and this does not cause discomfort to the subject. In addition, since the blood glucose level is automatically measured at the set time, the subject does not need to be aware of the time to measure the blood glucose level and can be measured at home. There is no heavy burden. Furthermore, since it can be automatically measured several times a day, it is possible to see changes in blood glucose level over time without placing a burden on the subject.
[0035]
In the above embodiment, the two electrodes 13 and 14 are provided on the back surface of the main body 11, but may be provided on the back surface of the wristband 12. Further, although the display device 20 is provided on the back surface of the lid 15, the display device 20 may be provided on the front surface 11 </ b> A of the main body 11 and the operation unit 19 may be provided on the back surface of the lid 15.
[0036]
In the above embodiment, the blood glucose level measuring device 10 to be worn on the arm has been described, but it may be worn on another part of the human body.
[0037]
FIG. 5 shows a second embodiment. In the second embodiment, the reference values P1a to P3a when the predetermined time T1 has elapsed from the respective peaks P1 to P3 of the personal reference data, and the predetermined values T1 to T3 from the respective peaks R1 to R3 of the measurement data. The measured values R1a to R3a are compared, and when the measured values R1a to R3a are larger than the reference values P1a to P3a by a predetermined value or more, the warning indicator 18 is blinked.
[0038]
FIG. 6 shows a third embodiment. In the third embodiment, when the difference between the reference graph (personal reference data) G2 and the measurement graph (measurement data) G1 exceeds a predetermined value, the exercise program that is preferably performed by the subject according to the difference. It is. For example, “Walking 60 minutes” or the like is displayed on the display 20. In this case, the walking time is changed according to the difference.
[0039]
The difference between the reference graph G2 and the measurement graph G1 is the difference when the measured value exceeds 20 percent or more from the maximum value P1, or the difference when the measured value falls by 20 percent or more from the minimum value Q1, and each of the measurement data The difference between the maximum value R1 to R3 for each peak and the maximum value P1 to P3 for each peak of the personal reference data, the reference value P1a when the predetermined time T1 has elapsed from the time of each peak P1 to P3 of the personal reference data It may be any difference between P3a and the measured values R1a to R3a when a predetermined time T1 has elapsed from each of the peaks R1 to R3 of the measurement data.
