Description

Blood glucose management system

The present invention relates to a blood glucose management system for managing the blood glucose level of a measurement subject.

Diabetes causes abnormalities such as sugar, protein, and fat metabolism, and blood glucose (blood sugar) accumulation and stagnation continue. Therefore, a diabetic patient is required to continuously perform blood glucose control, for example, performing self-blood glucose measurement (SMBG: self-monitoring of blood glucose) using a blood glucose measurement device. In recent years, a blood glucose measuring device having various functions has been developed in conjunction with an increase in the number of diabetic patients (see JP 2011-117911 A).

The blood glucose measurement device disclosed in Japanese Patent Application Laid-Open No. 2011-117911 includes an imaging means (camera unit) in order to confirm the relationship between the content of a meal eaten by a diabetic patient and the blood glucose level. That is, when the user of the blood glucose measurement device takes a picture of meal contents before meals, the blood glucose measurement device stores the captured meal image information and blood glucose level information in association with each other. Thereby, the user can confirm later what kind of meal the blood glucose level has become.

However, even if the blood glucose measuring device has a function of photographing meal contents as described above, the user often forgets to photograph the meal contents before the meal. For this reason, there is a shortage of data in which meal image information and blood glucose level information are associated with each other, resulting in inconvenience that cannot be fully utilized for blood glucose management.

The present invention has been made in view of the above circumstances, and by notifying the user to take a picture, the situation of forgetting to take a picture of the meal content is greatly reduced. An object of the present invention is to provide a blood sugar management system that allows a user to recognize the relationship of values well.

In order to achieve the above object, a blood glucose management system according to the present invention includes an apparatus main body capable of storing blood glucose level information of a measurement subject, and the apparatus main body acquires blood glucose level information to acquire the blood glucose level information. And a notification means for performing notification for prompting acquisition of image information based on the acquisition of the blood glucose level information.

According to the above, the blood glucose management system has the blood glucose level information acquisition unit and the notification unit, so that the user is notified to take a picture of the meal content based on the fact that the apparatus main body acquires the blood glucose level information before the meal. can do. Therefore, the user is conscious of photographing meal contents. As a result, the blood sugar management system can greatly reduce the situation in which the user forgets to take a picture of the meal content, and allows the user to better recognize the relationship between the meal content and the blood sugar level.

In this case, it is preferable that the apparatus main body includes a discriminating unit that discriminates a measurement before a meal or a measurement after a meal when the blood glucose level information is acquired.

As described above, when the determination unit determines the measurement before the meal or the measurement after the meal, the apparatus main body can more surely perform the notification of prompting the photographing of the meal contents based on the blood glucose level information acquired before the meal. .

Further, when the measurement before the meal is determined, the determination unit may measure a preset time width for photographing, and perform notification by the notification unit after the time width for photographing is elapsed. .

Thereby, the notification means can prompt the photographing of the contents of the meal after the lapse of the photographing time width. Therefore, for example, even when the user cannot eat right after measuring blood glucose levels before eating, the situation where the user forgets to take a picture of the meal content is further reduced by encouraging the user to take a picture near the time of eating. Can do.

Further, when the determination means determines the measurement before the meal, the determination means measures the blood glucose level measurement time width that is set in advance, and after the elapse of the blood sugar level measurement time width, the blood glucose level by the notification means A notification that prompts the acquisition of information may be performed.

Thereby, the notification means can prompt the measurement of the blood glucose level after the measurement time width elapses. Therefore, the situation where the user forgets to measure the blood glucose level after meals can be greatly reduced.

Alternatively, the discriminating unit measures a preset time width for blood glucose level measurement based on the fact that the apparatus main body has acquired the image information, and notifies the notification after the time width for blood glucose level measurement has elapsed. A notification that prompts the user to acquire blood glucose level information may be performed.

Thereby, the blood glucose management system can prompt the measurement of the blood glucose level based on the acquisition of the image information. Since the image information of the meal content is acquired immediately before the user has a meal, the determination means can more accurately identify the user's meal time, and can accurately notify the blood glucose level after the meal. Can be done.

Here, the blood glucose management system further includes a measurement unit that measures the blood glucose of the measurement subject and calculates a blood glucose level, and an image information acquisition unit that acquires the image information, and the blood glucose level information acquisition unit includes The blood glucose level calculated by the measuring unit is acquired and stored in a management database for managing a plurality of blood glucose level information, and the image information acquiring unit is acquired immediately before the acquisition of the image information and is stored in the management database. The image information can be associated with the blood glucose level information stored in the table.

In this way, the blood glucose management system easily displays the image information of the meal content when the user confirms the blood glucose level information later by associating the image information with the blood glucose level information stored in the management database. Can do. Therefore, the user can grasp the contents of the meal together with the fluctuation of the blood sugar level, and can be used for blood sugar management.

The photographing lens 24 is linked to a photographing unit 26 (camera) provided in the smartphone 12 and is used for projecting a subject when taking a picture of meal contents. The photographing unit 26 can use what is preinstalled in the smartphone 12. For example, the photographing unit 26 projects a moving image preliminarily on the display unit 20 via the photographing lens 24, and when the user operates the operation unit 22, the image information (still image) at that timing is extracted and stored in the memory. .

Furthermore, a speaker unit 28 and a smartphone side transmitting / receiving unit 30 are provided inside the smartphone 12. The speaker part 28 can use what was previously mounted in the smart phone 12 in order to output a sound (call voice, music, an alarm, etc.) from the smart phone 12 outside. The speaker unit 28 is used when performing a notification for taking a photograph or a notification for prompting the measurement of a blood glucose level in blood glucose management.

The smartphone-side transmitting / receiving unit 30 has a function capable of short-range wireless communication with various external devices. Examples of the short-range wireless communication standard include Bluetooth, ZigBee, and wireless LAN. As the blood glucose management application 16 is constructed, the smartphone-side transmission / reception unit 30 can wirelessly communicate with the blood glucose meter 14 and receive blood glucose level information G from the blood glucose meter 14. Note that the blood glucose level input to the smartphone 12 is not limited to wireless communication from the blood glucose meter 14, and may be wired communication, or may be manually input by the user referring to the display of the blood glucose meter 14, for example.

As shown in FIG. 1, the blood glucose meter 14 has a housing 32 that houses various mechanisms that enable blood glucose levels to be measured. On the surface of the housing 32, there are provided a display screen 34 for displaying a blood glucose level measurement result or a blood glucose level measurement guide or an error, and an operation button 36 operated by a user when the blood glucose level is measured. It has been. Further, a measurement chip 38 capable of sucking blood that has flowed out onto the user's skin is attached to the distal end portion of the housing 32. A measuring unit 40 (measuring means: see FIG. 2) for optically measuring the blood sucked into the measuring chip 38 is provided inside the housing 32.

In this case, the measurement unit 40 emits measurement light having a predetermined wavelength to blood soaked in a test paper (not shown) in the measurement chip 38, receives the reflected light, and calculates a blood glucose level based on the received light intensity. The blood glucose level measured by the measurement unit 40 is displayed on the display screen 34. In addition, the measurement of the blood glucose level by the blood glucose meter 14 is not particularly limited, and for example, an electrochemical measurement method that generates electricity based on a chemical reaction with a reagent can be taken.

Furthermore, a blood glucose level information management unit 42 and a blood glucose meter side transmission / reception unit 44 are provided inside the blood glucose meter 14. The blood glucose level information management unit 42 has a function of storing and managing the blood glucose level measured by the measurement unit 40 on the blood glucose meter 14 side, and displays the measured or stored blood glucose level and date / time on the display unit 20 or on the smartphone 12. Processing such as generating information that can be transmitted is performed.

The blood glucose meter side transmitting / receiving unit 44 has a function of performing short-range wireless communication with the smartphone 12. The blood glucose meter 14 can generate blood glucose level information G for external transmission by the blood glucose level information management unit 42 and transmit the blood glucose level information G from the blood glucose meter side transmission / reception unit 44 to the smartphone 12.

When the smartphone 12 receives the blood glucose level information G from the blood glucose meter 14, the blood glucose management application 16 appropriately processes and stores the blood glucose level information G. The blood glucose management application 16 performs information transmission among the display unit 20, the operation unit 22, the photographing unit 26, the speaker unit 28, and the smartphone-side transmission / reception unit 30 described above to perform a predetermined operation. The blood glucose management application 16 functions by the CPU and the memory of the smartphone 12, and an icon 16 a for turning on / off the blood glucose management application 16 is formed on the display unit 20. In addition, a management control unit 50 (discriminating means), a management database 52 (hereinafter, database is abbreviated as DB), and a voice DB 53 are constructed in the smartphone 12 by the blood sugar management application 16.

The management control unit 50 has a function of overall control of blood sugar level management in the smartphone 12. In general, when the blood glucose level information G is acquired, the blood glucose level information G before or after a meal is determined, triggered by the blood glucose level before the meal as a trigger, and a notification for encouraging photography after a predetermined time has passed, Encourage the measurement of postprandial blood glucose levels after elapse.

In order to realize the above processing, the management control unit 50 includes a blood glucose level information acquisition unit 54 (blood glucose level information acquisition unit), an image information acquisition unit 56 (image information acquisition unit), and display information that operate according to a program. A generation unit 58, a timing setting unit 60, a timer unit 62, and a notification unit 64 (notification unit) are provided. In the management control unit 50, a plurality of registers (meal processing flag 66, photographing flag 68, measurement flag 70) that hold a value of 0 or 1 based on the processing of each unit are formed.

The blood glucose level information acquisition unit 54 has a function of storing the blood glucose level information G transmitted from the blood glucose meter 14 in the management DB 52. Specifically, when the smartphone-side transmitting / receiving unit 30 is set in a wireless communicable state under the control of the management control unit 50 and receives blood glucose level information G from the blood glucose meter 14, the blood glucose level information G is temporarily stored. When the management control unit 50 determines that the blood glucose level information G temporarily stored is before or after a meal, the blood glucose level information G is stored in an appropriate location in the management DB 52. For example, when the determination result is blood glucose level information G before meal, it is newly stored in the management DB 52 as pre-meal blood glucose level information G1, and when the determination result is blood glucose level information G after meal, it is stored as post-meal blood glucose level information G2. It memorize | stores in management DB52 so that it may link with blood glucose level information G1.

The image information acquisition unit 56 has a function of associating the image information of the meal content photographed by the photographing unit 26 (hereinafter referred to as meal image information I) with the blood glucose level information G stored in the management DB 52. That is, after the blood glucose level information G is stored in the management DB 52 as a blood glucose level before a meal, image information captured after a predetermined time has been stored in the memory in association with the blood glucose level information G1 before the meal.

Further, the meal image information I may be configured not only to use the photographing unit 26 of the smartphone 12 but also to acquire the meal image information I photographed separately. For example, when photographing is performed with a camera, the smartphone 12 and the camera can take the information communication (wireless communication or wired communication) and take in the smartphone 12. Generally, since image information is accompanied by date and time information, the image information acquisition unit 56 can associate the pre-meal blood glucose level information G1 and the meal image information I based on the date and time.

The display information generation unit 58 has a function of collectively displaying the blood glucose level information G stored in the management DB 52 and the meal image information I stored in the memory on the display unit 20. The blood glucose level information G can be displayed in various ways, for example, a list showing the blood glucose values for each date and a graph showing changes in blood glucose levels. On the other hand, for example, the meal image information I may be linked so as to jump from the displayed blood sugar level to another screen, and displayed on the display unit 20 when the user touches the blood sugar level. Accordingly, the user can arbitrarily check the blood glucose level information G and the meal image information I by operating the operation unit 22.

The timing setting unit 60 sets the timing for prompting photography and the prompting for blood glucose measurement after meal when the management control unit 50 determines the blood glucose level before meal. Specifically, a time width (imaging time width, measurement time width) from the acquisition point of the pre-meal blood glucose level information G1 is set in advance, and when the pre-meal blood glucose level information G1 is acquired, the image capture time width and the measurement time width are read out. Is set in the timer unit 62.

In addition, the structure set after the photography of a meal content may be sufficient as the measurement time width | variety which encourages the blood glucose level measurement after a meal. That is, the timing setting unit 60 reads out the preset measurement time width based on the acquisition of the meal image information I of the smartphone 12 and sets it in the timer unit 62.

The photographing time width and the measurement time width can be set in advance by operating the operation unit 22 by the user. For example, the photographing time width is preferably set in the range of about 0 minutes to 30 minutes. The user shortens the shooting time width when eating immediately after measuring blood glucose levels according to his / her own lifestyle, and increases the shooting time width when meals are prepared after a certain amount of time due to eating out, etc. Set a long time. On the other hand, the measurement time width is preferably set to about 2 hours 30 minutes to 3 hours in consideration of meal time or the like based on the guidance of a doctor or the like when, for example, the timing after 2 hours has elapsed after meal is desirable. When the measurement time width is set based on the meal image information I, a time width shorter than the measurement time width set by acquiring the pre-meal blood glucose level information G1 is set.

The timer unit 62 measures time according to the set of the photographing time width and the measurement time width by the timing setting unit 60. The management control unit 50 monitors the measurement of the imaging time width and the measurement time width by the timer unit 62, and prompts the user to take a picture when the measurement time width measurement ends, and measures the blood glucose level as the measurement time width measurement ends. Prompt.

When the elapse of the photographing time width or the elapse of the measurement time width is determined by the measurement of the timer unit 62, the notification unit 64 selects an appropriate piece of voice guide information stored in the voice DB 53 and selects this. Voice guide information is output from the speaker unit 28. Thereby, the user is encouraged to perform photography of meal contents and blood glucose level measurement after meals from the smartphone 12 carried on a daily basis. In addition, the notification method of photography or blood glucose level measurement is not limited to the voice guide, and may be notified by an alarm, a screen display on the display unit 20, or vibration. Further, a plurality of the various methods described above may be combined, and the user himself / herself may arbitrarily set music or the like.

The voice DB 53 manages a plurality of types of voice guide information for encouraging photography and blood glucose level measurement. For example, the voice guide information that prompts you to take a picture is selected, such as “Let's take a picture of a meal”, and the voice guide information that prompts you to measure a blood glucose level is “Let's measure your blood sugar level”. Selected. The notification unit 64 monitors the shooting flag 68 and the measurement flag 70, reads appropriate voice guide information from the voice DB 53, and outputs it to the outside via the speaker unit 28.

Also, the meal processing flag 66 constructed in the management control unit 50 is set when the management control unit 50 determines that the blood glucose level information G is before meal (0 → 1). Accordingly, the management control unit 50 performs a process flow when the user has a single meal, and performs a process of prompting acquisition of the meal image information I and acquisition of the blood glucose level information G. The meal processing flag 66 is cleared when the postprandial blood glucose level information G2 is acquired (0 → 1).

The photographing flag 68 is set when the management control unit 50 determines that the blood glucose level information G is before a meal (0 → 1) in the same manner as the meal processing flag 66. The timing setting unit 60 sets the shooting time width when the shooting flag 68 is 1, and the timer unit 62 measures the set shooting time width. In addition, the notification unit 64 selects the sound that prompts the user to take a picture when the shooting flag 68 is 1. The photographing flag 68 is cleared when the meal image information I is acquired (0 → 1).

The measurement flag 70 is set when the management control unit 50 determines that the blood glucose level information G is pre-meal (0 → 1) in the same manner as the meal processing flag 66 when the measurement time width is set based on the blood glucose level measured before the meal. And). The timing setting unit 60 sets the measurement time width when the measurement flag 70 is 1, and the timer unit 62 measures the set measurement time width. The measurement flag 70 is cleared when the postprandial blood glucose level information G2 is acquired (0 → 1). Further, when the measurement time width is set based on the acquisition of the meal image information I, the measurement flag 70 may be set instead by determining that the shooting flag 68 has been dropped.

As shown in FIG. 3, the management DB 52 of the blood glucose management application 16 stores pre-meal blood glucose level information G1 and post-meal blood glucose level information G2 in parallel according to the date and time. Further, the meal image information I stored in the memory is managed in association with the pre-meal blood glucose level information G1 and the post-meal blood glucose level information G2 related to the meal. That is, the management DB 52 manages the meal image information I by specifying the address space of the meal image information I stored in the memory.

Further, the blood sugar management application 16 can transmit the management DB 52 stored in the smartphone 12 to a predetermined computer via the smartphone-side transmitting / receiving unit 30. For example, a doctor or the like can obtain the management DB 52 from the smartphone 12 and check the patient's blood glucose level to better guide the patient on diet therapy or the like.

The blood sugar management system 10 according to the first embodiment is basically configured as described above. Hereinafter, a blood sugar management method (processing flow of the management control unit 50) using the system 10 is shown in FIG. This will be explained based on the above, and the effects will be described in detail.

The blood glucose management application 16 of the system 10 is activated (starts processing) by operating the icon 16a on the display screen 34 of the smartphone 12 in order for the user to manage his / her blood glucose level (step S1). Here, when the blood glucose management application 16 is activated, it is preferable to perform a substantial processing flow by prompting the user to input a preset password and determining whether the password matches. This improves security. With this activation, the management control unit 50 can display the pre-meal blood glucose level information G1, the post-meal blood glucose level information G2, and the meal image information I stored in the past in a table or graph.

Moreover, the blood glucose level information acquisition part 54 waits for the smart phone side transmission / reception part 30 in the state which can be wirelessly communicated with the blood glucose meter 14 after starting, and discriminate | determines whether the blood glucose level information G was acquired from the blood glucose meter 14 ( Step S2). The blood glucose management application 16 may be configured to automatically start based on the reception of the blood glucose level information G from the blood glucose meter 14 without starting at normal time (that is, not performing Step S1).

When the management control unit 50 receives the blood glucose level information G from the blood glucose meter 14 via the smartphone-side transmission / reception unit 30, the management control unit 50 determines whether the blood glucose level is measured before the meal or the blood glucose level measured after the meal (step S3). The determination by the management control unit 50 is performed by confirming the state of the meal processing flag 66. That is, when the meal process flag 66 is 0, it is determined as blood glucose level information G before a meal, and when the meal process flag 66 is 1, it is determined as blood glucose level information G after a meal.

The discrimination by the management control unit 50 is not limited to the above method, and various methods can be taken. For example, as another discrimination method, a method based on a time zone can be cited. That is, if it is 6 am to 8 am, 11 am to 1 pm, 6 pm to 8 pm, the blood glucose level information G before meal is used. Determine that there is. Moreover, the time width from the blood glucose level information G acquired last time may be measured. For example, if it is 3 hours or more, it may be determined as blood glucose level information G before a meal if it is within 3 hours. Furthermore, a threshold value of a blood glucose level before a meal may be set in advance based on a plurality of blood glucose level information G acquired, and the blood glucose level information G before the meal may be determined if the threshold is equal to or less than the threshold value. Furthermore, the management control unit 50 may display on the display unit 20 that the blood glucose level information G has been acquired as the blood glucose level information G is input, and may allow the user to select before meals or after meals during this display. .

In step S3, when the management control unit 50 determines the pre-meal blood glucose level information G, the blood glucose level information acquisition unit 54 stores the acquired blood glucose level information G in the management DB 52 as pre-meal blood glucose level information G1 (step S4). In addition, the blood sugar level information acquisition unit 54 sets the meal processing flag 66, the imaging flag 68, and the measurement flag 70 to 1 based on the discrimination result before meal (step S5).

In step S5, the timing setting unit 60 sets the preset shooting time width when the shooting flag 68 is set to 1 in the timer unit 62, and sets the measurement time 70 set when the measurement flag 70 is 1 in advance. The width is set in the timer unit 62 (step S6). Thereby, the timer unit 62 starts time measurement based on the set photographing time width and measurement time width.

Thereafter, the management control unit 50 determines the elapse of the shooting start time of the meal contents based on the measurement of the timer unit 62 (step S7). When it is determined that the shooting start time has elapsed, the notification unit 64 reads the voice data that prompts the user to take a picture stored in the voice DB 53, and performs a notification that prompts the user to take a meal via the speaker unit 28 (step S8).

After this notification, the management control unit 50 enters a standby state, and determines whether or not the user has taken a picture by the photographing unit 26 of the smartphone 12 and acquired the meal image information I (step S9). In addition, since what the user image | photographed does not necessarily copy the content of a meal, you may confirm whether it is the meal image information I with respect to a user. Further, when the meal image information I is input from the user during the time measurement of the timer unit 62 (that is, when a photograph is taken), step S10 is performed without notification.

When the acquisition of the meal image information I is determined by photographing by the photographing unit 26, in step S10, the image information acquisition unit 56 associates the pre-meal blood glucose level information G1 and the meal image information I stored in the management DB 52 with each other. Meal image information I is stored. Then, the image information acquisition unit 56 sets the shooting flag 68 to 0.

Note that the timer unit 62 measures the time of the measurement timer during steps S7 to S11 because the measurement flag 70 is 1. Therefore, the management control unit 50 determines the elapse of the blood sugar level measurement time based on the measurement of the timer unit 62 (step S11). When the elapse of the measurement time is determined, the notification unit 64 reads out the voice data that prompts the measurement of the blood glucose level stored in the voice DB 53, and performs notification that prompts the measurement of the blood glucose level via the speaker unit 28 ( Step S12).

After this notification, the process returns to step S2, and the management control unit 50 determines reception of the blood glucose level information G from the blood glucose meter 14. When the blood glucose level information G is received, the management control unit 50 determines that the blood glucose level information G is after meal by confirming that the meal processing flag 66 is 1 in step S3, and step S13. Proceed to

In step S13, the blood glucose level information acquisition unit 54 stores the acquired blood glucose level information G as postprandial blood glucose level information G2 in the management DB 52 so as to be associated with the pre-meal blood glucose level information G1 and the meal image information I stored in advance. save. Thereby, the pre-meal blood glucose level information G1, the post-meal blood glucose level information G2, and the meal image information I in one meal are stored in the management DB 52.

Finally, the management control unit 50 sets the meal processing flag 66 and the measurement flag 70 to 0 (step S14), and ends the series of processing flows.

When the timing for prompting the measurement of blood glucose level after meal is set based on photography, the measurement flag 70 remains 0 in step S5 and is set by changing the imaging flag 68 from 1 to 0 in step S10. . Thereby, the timer unit 62 sets a predetermined measurement time width and performs time measurement for performing notification for prompting measurement of the blood glucose level after a meal.

The system 10 can promptly notify the blood glucose level measurement by setting the time width of the notification prompting the measurement of the blood glucose level after the meal based on the acquisition time point of the meal image information I. That is, since the acquisition of the meal image information I is performed immediately before the user has a meal, the management control unit 50 can identify the user's meal time more accurately and prompts the user to measure the blood glucose level after the meal. Can be performed with high accuracy.

In addition, the management control unit 50 may have a snooze function in acquiring the meal image information I and the blood glucose level information G. For example, after the notification of prompting the photographing of meal contents by the notification unit 64 or the notification of prompting the measurement of blood glucose level, the acquisition of the meal image information I or the acquisition of blood glucose level information G even after a predetermined time has elapsed. If it is not determined, notification is performed again. Since the photographing flag 68 and the measurement flag 70 are 1 until the meal image information I and the postprandial blood glucose level information G2 are acquired, the management control unit 50 (timer unit 62) acquires information by monitoring each flag. Can be reliably determined. That is, the snooze function can be easily and effectively implemented by using the shooting flag 68 and the measurement flag 70.

In addition, the management control unit 50 takes a picture when the acquisition of the meal image information I or the blood glucose level information G is not determined for a predetermined time (long time) after the notification prompting the photographing of the meal content or the notification prompting the measurement of the blood sugar level. It is preferable to reset (drop) the flag 68 and the measurement flag 70. Thereby, it is possible to reliably determine that the blood glucose level information G before the next meal is before a meal.

As described above, the blood glucose management system 10 according to the first embodiment includes the blood glucose level information acquisition unit 54 and the notification unit 64, and thus captures the contents of meals based on the acquisition of the blood glucose level information G before the meal. The user can be notified to do so. Therefore, the user is conscious of photographing meal contents. As a result, the system 10 can greatly reduce the situation where the user forgets to take a picture of the meal contents. Moreover, the user can recognize the relationship between the meal content and the blood glucose level well.

In this case, the management control unit 50 discriminates the measurement before the meal or the measurement after the meal, so that the smartphone 12 more reliably performs the notification of prompting the photographing of the meal contents based on the blood glucose level information G acquired before the meal. Can do.

Further, the system 10 can make a notification that prompts the notification unit 64 to shoot meal contents after the lapse of the shooting time width measured by the timer unit 62. Therefore, for example, even when the user cannot eat right after measuring blood glucose levels before eating, the situation where the user forgets to take a picture of the meal content is further reduced by encouraging the user to take a picture near the time of eating. Can do. Further, the system 10 can prompt the blood glucose level to be measured by the notification unit 64 after the measurement time width measured by the timer unit 62 has elapsed. Therefore, the user can greatly reduce the situation of forgetting to measure the blood glucose level after meals.

The system 10 associates (links) the meal image information I with the blood glucose level information G stored in the management DB 52 so that the meal image information I can be easily obtained when the user confirms the blood glucose level information G later. Can be displayed. Thereby, the user can grasp the content of the meal together with the fluctuation of the blood glucose level, and can use it for blood glucose management (improvement of the content of meal, etc.).
