Abstract

A notification system (10) is provided with a meal-time-setting unit (42) for setting meal-time information, a meal-data-setting unit (44) for setting information based on meal content, a calculation processor (24) for setting the time for starting measurement of a blood sugar value using information based on the meal-time information and meal content, and an alarm-generating unit (34) for notification of the start of the blood sugar value measurement based on the measurement-start time set by the calculation processor (24).

Description

Notification system

The present invention relates to a notification system that informs a user of a measurement start time in blood glucose measurement performed after a meal.

Diabetes causes abnormalities such as sugar, protein, and fat metabolism, and blood glucose (blood sugar) accumulation and stagnation continue. Therefore, a diabetic patient (hereinafter also referred to as a user) is required to continuously perform blood glucose management (blood glucose control). For example, in blood glucose management, blood glucose level self-measurement (also called self-monitoring of blood glucose: SMBG) is performed using a blood glucose measurement device (see International Publication No. 2008/136437).

The blood sugar level starts to rise gradually from the time of eating, reaches the highest peak value when a certain amount of time has passed, and then shows a mountain shape that gradually falls. In blood glucose management, it is important to measure the peak value (or near the peak value) of blood glucose level after meals and recognize the peak value in order to make use for treatment (for example, instruction on meal contents and meal methods). It is said that.

By the way, in SMBG, a diabetic patient forgets to make a measurement or misunderstands and does not measure a blood glucose level or at a time significantly deviated from a time to be measured (a time near a blood glucose peak value). There are inconveniences such as measuring. For this reason, in the measuring apparatus disclosed in International Publication No. 2008/136437, when a predetermined time (for example, 2 hours) elapses after eating, an alarm sound is sounded to prompt the user to measure the blood sugar level. .

However, since various nutrients (for example, carbohydrates, proteins, lipids, and the like) ingested by meals have different rates and speeds of changing to blood sugar, the time during which the blood sugar level rises greatly varies depending on the contents of the meal. For example, when a carbohydrate-based meal is used and when a lipid-based meal is used, the carbohydrate-based meal has a faster blood sugar level rise time. Therefore, even if the measuring device disclosed in International Publication No. 2008/136437 reports that the blood glucose level is measured after a predetermined time since meal, the blood glucose level peak value (or near the peak value) is not necessarily displayed. The problem that it cannot measure and blood glucose control is not made enough arises.

The present invention has been made to solve the above-described problem, and sets a time when the blood glucose level is close to the peak value after a meal based on the content of the meal, and notifies the user of the time by changing the blood glucose level. An object of the present invention is to provide a notification system that facilitates measurement and thereby can better manage blood glucose.

In order to achieve the above object, the present invention provides meal time setting means for setting meal time information, meal data setting means for setting information based on meal contents, and the meal time set by the meal time setting means. Control side time setting means for setting a blood glucose level measurement start time using information and information based on the meal content set by the meal data setting means, and the measurement start time set by the control side time setting means And a notification means for notifying the time when the blood glucose level should be measured or the arrival of the time.

According to the above, the control-side time setting means sets the blood glucose level measurement start time using the meal time information and information based on the meal content, and the notification means should measure the blood sugar level based on the measurement start time. By notifying the time or the arrival of the time, the blood glucose level measured after a meal can be measured near the peak value at which the blood glucose level rises most. In other words, by using information based on meal content, it is possible to relatively easily determine the time it takes for nutrients ingested to be converted into blood sugar, and predict when the blood sugar level is near the peak value. It is possible to notify the user. As a result, the user can easily recognize the blood glucose level near the peak value, and can perform blood glucose management well.

In this case, the information based on the meal content may be a carbo value indicating the amount of carbohydrate for each meal content.

Thus, by using the carbo value indicating the amount of carbohydrate for each meal content as the information based on the meal content, it is possible to predict the time during which the carbohydrates consumed in the meal are converted into blood sugar. Therefore, if the blood glucose level measurement start time is set from the carbo value, the blood glucose level near the peak value can be measured.

Further, it may comprise database storage means for storing the carbo value for each meal content as a database, and display means for displaying the meal content associated with the carbo value.

Thus, if the meal content associated with the carbo value is displayed by the display means, the user can easily use the carbo value based on the displayed meal content.

Furthermore, the meal data setting means may set the carbo value of the selected meal content by selecting the meal content displayed by the display means.

Thereby, since the user can use the carbo value only by selecting the meal content displayed by the display means, the user can omit the work of converting the meal content into the carbo value. The measurement start time of the value can be set more easily.

Here, the control-side time setting means calculates the total value of the carbo value in a single meal, sets the amount of time until the blood glucose level becomes close to the peak value after eating based on the total value, The measurement start time of the blood glucose level can be set by adding the amount of time to the meal time information.

Thus, by setting the amount of time during which the blood sugar level increases from the total value of the carbo values in one meal, the blood glucose level measurement start time can be set easily. In this case, even if the user himself / herself does not set the blood glucose level measurement start time, the notification means notifies the time when the blood glucose level should be measured based on the blood glucose level measurement start time or the arrival of the time, so that the user It is possible to avoid forgetting to measure the value.

In addition, a user time setting unit is provided for a user to set the measurement start time of the blood glucose level, and the control side time setting unit calculates a total value of the carbo values in one meal, and based on the total value, It is also possible to set an amount of time for which the value is near the peak value, and reset the measurement start time set by the user time setting means based on the amount of time.

As described above, when the user sets the blood glucose level measurement start time in advance through the user time setting means, the start of blood glucose level measurement can be notified when the carbo value is not used. Also, when using the carbo value, if the measurement start time set via the user time setting means is reset based on the total value of the carbo value, the blood glucose level measurement start time can be easily changed (shifted). Thus, the blood glucose level near the peak value can be measured.

Furthermore, it is preferable to have a table associating the amount of time with the carbo value, and the control-side time setting means sets the amount of time based on the total value with reference to the table.

Thus, if the time amount is set with reference to the table in which the time amount and the carbo value are associated with each other, the blood glucose level measurement start time can be set more easily by the control side time setting means.

Here, it is preferable that the notification system is provided in a blood glucose measurement device that measures a blood glucose level contained in blood.

As described above, by providing the blood glucose measurement device with the notification system, the blood glucose measurement device can be used to measure the blood glucose level according to the blood glucose measurement start time notified by the blood glucose measurement device.

In this case, the blood glucose measuring device stores the blood glucose level measurement start time set by the control-side time setting means in association with the blood glucose level measured within a predetermined time before and after the measurement start time. It is preferable to have value data storage means.

In this way, by storing the blood glucose level measurement start time and the blood glucose level measured within a predetermined time before and after the measurement start time in association with each other, the user or doctor can recognize the blood glucose level near the peak value for each meal. Blood glucose control can be performed more satisfactorily.

According to the present invention, after the meal, the time when the blood sugar level is close to the peak value is set based on the content of the meal, and the time is notified to the user to facilitate the measurement of the blood sugar level, thereby performing the blood sugar management well. can do.

Hereinafter, preferred embodiments of the notification system according to the present invention will be described in detail with reference to the accompanying drawings. The “time” in the description of the present embodiment is used to mean a certain point in the day, such as 12:00, 12:30, and the like. Is used to mean the length (length) from one point in time to another point in time, such as 1 hour, 1 hour 30 minutes, etc., and “time” includes the concept of time and amount of time. Used in meaning.

First, as a premise for explaining the notification system according to the present embodiment, the relationship between meal content and blood glucose level change and the relationship between meal content and carbo value will be described in detail.

FIG. 1 is a graph showing changes in meal time and blood glucose level in vivo according to the present invention, and FIG. 2 is a table showing an example of the correspondence between meal contents and carbo values.

As shown in FIG. 1, it is known that a human body has a different rate and time (that is, speed) at which nutrients taken by meals change into blood sugar (glucose). For example, carbohydrates have a rate of change to glucose of approximately 100% and are digested relatively easily, so that the largest amount of carbohydrates changes to glucose around 1 hour after meals. On the other hand, protein has a rate of change to glucose of approximately 50%, and gradually changes to glucose as compared with carbohydrates. Therefore, the largest amount of protein changes to glucose around 3 hours after meal. In addition, since the rate of change of lipid to glucose is less than 10% and it takes time to digest, the peak of the amount of change to glucose is around 10 hours after meal.

That is, the rate of increase in blood glucose level after a meal differs depending on the content of the meal (nutrients in the meal), so it becomes difficult to set the time (time amount) at which the blood glucose level rises after the meal and reaches a peak value. In conventional blood glucose management, a doctor is often instructed uniformly and empirically to measure a blood glucose level 2 hours after meals.

Here, in order to simply determine an increase in blood glucose level, a counting method using carbo values (carbo count) is conceivable. This carbocount is used when adjusting the dose of insulin that stabilizes blood sugar. This “carbo value” is an index indicating the amount of carbohydrate contained in the meal content. For example, by setting the carbohydrate amount of 10 g to 1 carbo, the carbo value is converted for each meal content.

For example, as shown in the table of FIG. 2, the carbo value is 5.5 for rice (150g: one teacup), the carbo value is 3.0 for bread (60g: one cut), and fried shrimp (two fish) ), The carbo value can be converted for each meal content such as 1.0. If this carbo value is high, the amount of carbohydrate taken during the meal will be large, and it can be predicted that the amount of change to blood sugar will increase and the time for the blood sugar value to reach its peak value will be accelerated.

The notification system according to the present invention predicts the amount of time that the blood glucose level rises by effectively using the “carbo value” that has been used only for adjusting the amount of insulin in the past, and the blood glucose level reaches the peak value. The time (or the time in the vicinity thereof) is notified to the user, and the blood glucose level is measured.

The notification system 10 is built in a blood glucose measurement device 12 that actually measures the blood glucose level contained in the blood. Therefore, the configuration of the blood glucose measurement device 12 will be described in detail first. In addition, the alerting | reporting system 10 is applicable not only to the blood glucose measuring device 12 but to various devices. For example, the notification system 10 may be provided in a mobile terminal (for example, a mobile phone, a PHS, a PDA, a mobile game machine, a portable computer, a wearable computer, etc.), an alarm device, a digital watch, or the like.

FIG. 3 is a perspective view showing a blood glucose measurement device 12 to which the notification system 10 according to the embodiment of the present invention is applied, and FIG. 4 is a block diagram showing the structure of the blood glucose measurement device 12 of FIG.

The blood glucose measurement device 12 is constituted by an elongated casing 14 whose front end is slightly bent downward, and a display panel 16 (display means) and operation buttons 18 are provided on the upper surface of the casing 14. Further, a measurement chip 20 for actually collecting blood from a human body and an eject button 22 for removing the measurement chip 20 are provided on the distal end side of the housing 14.

The housing 14 of the blood glucose measurement device 12 is formed in a fitting shape that is easy for a user who self-measures blood glucose levels to hold with one hand, and the measurement chip 20 on the distal end side can be easily set as a measurement location (blood collection location) by a user operation. It is configured so that it can be pressed against. Inside the housing 14 is housed an internal mechanism used for blood glucose level measurement. In this case, as shown in FIG. 4, the internal mechanism includes an arithmetic processing unit 24 (control unit), a storage unit 26, a power source 28, a measurement unit 30, a data transmission / reception unit 32, an alarm generation unit 34 (notification unit), a timer. 36 (time measuring means). The blood glucose measurement device 12 performs measurement of blood glucose level, storage and display of the measured blood glucose level data, transmission of blood glucose level data, and the like (hereinafter collectively referred to as blood glucose level measurement processing) by these internal mechanisms.

As shown in FIG. 3, the display panel 16 is arranged on the upper surface of the housing 14 so as to have a relatively large display area. The display panel 16 can be constituted by, for example, a liquid crystal monitor or an organic EL. The display panel 16 is connected to an internal mechanism in the blood glucose measurement device 12 and displays information (for example, blood glucose level, date / time, error, etc.) necessary for blood glucose level measurement processing based on the control of the arithmetic processing unit 24.

On the other hand, the operation button 18 is a push-type button, and is disposed at a position adjacent to the display panel 16 on the top surface of the housing 14. Thereby, the user can perform an operation necessary for the blood glucose level measurement process by pressing the operation button 18 while checking the information displayed on the display panel 16.

Of course, the blood glucose measurement device 12 is not limited to the configuration including the display panel 16 and the operation buttons 18 as described above. For example, by adopting a touch panel type display panel, the blood glucose measurement process is performed. You may make it perform a display and operation integrally.

As shown in FIG. 4, the arithmetic processing unit 24 provided in the blood glucose measurement device 12 is configured using a known microcomputer (microprocessor: MPU) or the like. The arithmetic processing unit 24 reads out necessary programs and data from the storage unit 26 and performs arithmetic processing.

The storage unit 26 includes a ROM and a RAM, and a measurement program necessary for performing the blood glucose level measurement process is stored in the ROM in advance, and a plurality of data for storing the data measured by the blood glucose measurement device 12 is stored. A data area is allocated to an address space on the RAM.

As the power source 28, for example, a button-type battery, a round battery, a square battery, a secondary battery, an external power source, or the like can be applied. The power supply 28 supplies necessary power to the arithmetic processing unit 24, the storage unit 26, the measurement unit 30, the data transmission / reception unit 32, the alarm generation unit 34, the timer 36, and the like that are driven by power in the blood glucose measurement device 12.

The measuring unit 30 has a function of actually measuring the blood sugar level in the blood sugar measuring device 12. For example, the measurement unit 30 includes a light-emitting element (light-emitting diode), a light-receiving element (photodiode), a lens, a measurement circuit, and the like (not shown), and a mechanism that optically measures blood glucose levels in blood (light reflectance measurement method). Can be configured. Of course, the measurement unit 30 is not limited to an optical measurement mechanism. For example, the blood glucose level is measured electrically (electrochemical method) by an enzyme electrode method using glucose oxidase (GOD) or the like. It is good also as a mechanism.

The data transmitter / receiver 32 has a function of transmitting / receiving data to / from an external computer via an external transmitter / receiver. In this case, when the blood glucose measurement device 12 is brought close to the external transceiver, power is supplied from the external transceiver by electromagnetic induction, and the transmission data of the data transceiver 32 is automatically sent to the external transceiver (non-contact communication). If it is a function), workability can be improved.

The alarm generation unit 34 is configured as a speaker that outputs various sounds, and has a function of emitting a predetermined sound (alarm) to the outside of the blood glucose measurement device 12 based on the control of the arithmetic processing unit 24. For example, as a method of using the alarm generation unit 34 in the blood glucose level measurement process, it may be applied to various processes such as notifying the completion of the blood glucose level measurement, notifying the low battery level, and notifying the occurrence of an error. it can.

Furthermore, the timer 36 is provided for managing the time (date and time) in the blood glucose measurement device 12. The timer 36 is configured to automatically measure the time regardless of whether the power is on or off.

The blood glucose measurement device 12 measures the blood glucose level by linking the above-described components, and stores or transmits the measured blood glucose level data. Specifically, blood glucose level measurement using the blood glucose measurement device 12 will be described. First, the measurement chip 20 is attached to the distal end side of the housing 14 in order to collect the user's blood. Then, the measurement chip 20 is brought into contact with the fingertip of the user who has grasped the housing 14 and blood has flowed out. As a result, blood is sucked through the measuring chip 20, soaks into a test paper (not shown) accommodated therein, and the test paper is colored according to the amount of glucose in the blood.

After collecting the user's blood, the blood glucose measurement device 12 drives the measurement unit 30 to measure the blood glucose level. In this case, the test paper is irradiated with irradiation light from the light emitting element of the measurement unit 30, and the reflected light reflected by the test paper is received by the light receiving element, and the amount of light is measured.

The arithmetic processing unit 24 operates in accordance with a measurement program, and calculates the degree of coloration (density) of the test paper and the red density of red blood cells based on the amount of light measured by the measurement unit 30. At this time, blood glucose level data can be obtained by quantifying the glucose concentration while correcting the glucose value obtained from the color concentration using the hematocrit value obtained from the red concentration. This blood glucose level data is stored in a blood glucose level data storage area 38 (see FIG. 5) of the storage unit 26.

In addition, after the measurement is completed, an operation for removing the measurement chip 20 from the housing 14 is performed. In this case, the measurement chip 20 is removed by operating the eject button 22 with one hand. Thereby, the disposal process can be performed easily and quickly without touching the measuring chip 20. Thus, the user can easily self-measure the blood glucose level by using the blood glucose measuring device 12.

Here, in the blood glucose management of diabetic patients, as described above, it is important to measure the vicinity of the peak value of blood sugar level that rises after meals. For this reason, the notification system 10 according to the present invention sets a time (blood glucose level measurement start time) in which the blood glucose level rises after the meal and becomes around the peak value, and notifies the user of the measurement start time (hereinafter, referred to as “the blood glucose level measurement start time”). In order to distinguish from the blood glucose level measurement process, it is also referred to as a notification process). This notification system 10 is configured using the internal mechanism of the blood glucose measurement device 12 described above.

FIG. 5 is a functional block diagram showing the notification system 10 provided in the blood glucose measurement device 12 of FIG.

As shown in FIG. 5, a program (hereinafter, referred to as a measurement start setting program 40) related to the notification process is stored (stored) in the storage unit 26 of the blood glucose measurement device 12 in advance. The notification system 10 performs notification processing by the arithmetic processing unit 24 operating according to the measurement start setting program 40. Examples of the notification process include setting of meal time and meal content, setting of blood glucose level measurement start time, and notification based on the measurement start time.

In this case, the display panel 16 of the blood glucose measurement device 12 is configured to receive information necessary for setting the blood glucose level measurement start time by the notification system 10 based on the control of the arithmetic processing unit 24 operating according to the measurement start setting program 40 (for example, meal Time (meal start time), meal content, carbo value, measurement start time, etc.) can be displayed. Similarly, the operation button 18 can be used for various operations for setting a blood glucose level measurement start time and the like.

The notification system 10 also includes a meal time setting unit 42 (meal time setting unit), a meal data setting unit 44 (meal data setting unit), and a control-side time setting unit in the arithmetic processing unit 24 based on the measurement start setting program 40. 46 (control time setting means) and a user time setting section 47 (user time setting means) are provided. Correspondingly, a meal time storage area 48, a meal data storage area 50, and a measurement start time storage area 52 are formed in the data area of the storage unit 26. Furthermore, a carbo value database 56 and a time amount reference table 58 that are necessary information in the notification process are stored in the storage unit 26 in advance in the database storage area 54 (database storage means).

The meal time setting unit 42 stores meal time information in the meal time storage area 48 of the storage unit 26 based on an operation instruction from the user. Here, the “meal time information” is data relating to the time when the user has a meal, and the user inputs the time as meal time information to the blood glucose measuring device 12 after (or before) taking the meal. To do. When the user inputs the meal time information, it may be input as a time such as 12:00, 12:30, etc. On the other hand, one hour after the current time measured by the

timer

36, 1 hour 30 minutes It may be entered as an amount of time as later. However, the meal time storage area 48 is preferably stored as time information in order to easily have a correspondence with the time measured by the timer 36.

In addition, since the notification system 10 according to the present embodiment is configured to convert the setting of the measurement start time of the blood sugar level after a meal, the measurement accuracy can be improved by setting the meal time information after the meal. Of course, meal time information may be set by predicting the end time of a meal before meals, and if meals do not take much time, setting a meal time information before or during meals as a meal time information is a big error. It will not be.

In setting meal time information, since the time is measured by the timer 36, the user operates the operation button 18 based on the time of the timer 36 so that the meal time information is appropriately input and the meal time information is set. It can be stored in the storage area 48. Further, the blood glucose measurement device 12 may be provided with a dedicated button for inputting time, and the dedicated time may be automatically set as mealtime information by pressing the dedicated button once after the meal ends. . Furthermore, when the time to eat every day is approximately the same time zone, the meal time may be registered (stored) in the meal time storage area 48 in advance. In this case, a plurality of meal time information such as breakfast, lunch and dinner can be stored in the meal time storage area 48. Based on the time measured by the timer 36 and the meal time information stored in advance, the arithmetic processing unit 24 automatically activates the blood glucose measurement device 12 when the meal time is reached (or approaches), and is the meal time for the user. This may be notified and the input of the carbo value may be prompted.

The meal time information stored in the meal time storage area 48 is read when the arithmetic processing unit 24 performs a predetermined notification process (for example, setting a measurement start time of a blood sugar level), and is used for calculation. Used as data.

On the other hand, the meal data setting unit 44 stores information based on the meal contents in the meal data storage area 50 of the storage unit 26 based on an operation instruction of the user. Here, as “information based on meal content”, the carbo value indicating the amount of carbohydrate for each meal content described in the premise of the present invention is used.

That is, the meal data setting unit 44 stores (sets) the carbo value as numerical data in the meal data storage area 50 when the user operates the operation button 18. In this case, the carbo value for each meal content (item) in one meal is added by the user and stored in the meal data storage area 50 as a total value. Further, the blood glucose measuring device 12 may have a calculation function (not shown), and when the carbo value for each meal content is input by the user, the total value of the carbo values may be calculated. Further, the carbo value for each meal content may be stored in association with the meal time information stored in the meal time storage area 48. Even in this case, the arithmetic processing unit 24 can calculate the blood glucose level measurement start time by collectively reading and adding meal contents taken at the same time (time zone).

As described above, the carbo value database 56 is stored in the database storage area 54 of the storage unit 26 in advance. The carbo value database 56 is, for example, a plurality of data groups to which carbo values are assigned for each meal content as shown in FIG. The arithmetic processing unit 24 reads the carbo value database 56 based on the user's operation and displays it on the display panel 16. Thereby, the user can input the carbo value into the meal data storage area 50 while confirming the carbo value in the displayed carbo value database 56.

As a display method of meal contents using the carbo value database 56, for example, a large classification (main meal, rice, noodles, etc.) shown in FIG. 2 is selected, and further detailed classification (rice, rice cake, bread, etc.) is selected. It is conceivable to adopt a tree format that allows selection.

In addition, the meal data setting unit 44 allows the user to select the meal content (the carbo value database 56) displayed on the display panel 16 without directly inputting the carbo value. The carbo value may be stored in the meal data storage area 50. In this case, when a touch panel is adopted as the display panel 16, a plurality of meal contents registered in the carbo value database 56 can be displayed on the display panel 16 and selected by the user. It can be made easier.

In the storage unit 26 (for example, the database storage area 54), in addition to meal contents and carbo values, photo data associated with the meal contents may be stored. The photographic data associated with the meal content is displayed on the display panel 16, thereby making it easier for the user to input (select) the carbo value for each meal content.

Moreover, the control side time setting unit 46 actually sets the meal time information set by the meal time setting unit 42 and the carbo value set by the meal data setting unit 44 from the meal time storage area 48 and the meal data storage area 50, respectively. Read and set (calculate) blood glucose level measurement start time information. “Measurement start time information” is data relating to the time when the user measures the blood glucose level after eating. The blood glucose level measurement start time information set by the control side time setting unit 46 is stored in the measurement start time storage area 52. The specific operation of the control side time setting unit 46 will be described later.

Furthermore, the user time setting unit 47 has a function of storing blood glucose level measurement start time information in the measurement start time storage area 52 of the storage unit 26 based on a user operation instruction. As the measurement start time information, the user may input (set) a scheduled blood glucose level measurement start time based on, for example, the time measured by the timer 36, or as an amount of time such as 2 hours after meal. It may be input (set) to have a correspondence with the meal time information.

As will be described later, the notification system 10 can calculate and set blood glucose level measurement start time information based on meal time information and a carb value. Measurement start time information can also be stored in the measurement start time storage area 52. For example, the carbo value may not be known depending on the meal content, and there is a possibility that the measurement start time cannot be set using the carbo value. For this reason, for example, if measurement start time information is registered in advance, such as 2 hours after a meal, it is possible to notify the start of blood glucose measurement corresponding to various situations.

In the notification system 10, the arithmetic processing unit 24 performs processing according to the measurement start setting program 40 to operate each of the setting

units

42, 44, 46, and 47, and stores various information input by the user in the storage unit 26. It memorize | stores in area |

region

48,50,52. The arithmetic processing unit 24 appropriately reads information (data) stored in the storage unit 26 and calculates a time (measurement start time) near the peak value of the blood sugar level that rises after a meal. In the notification system 10 according to the present embodiment, the measurement start time of the blood glucose level can be obtained relatively easily based on the meal time information and the carbo value (information based on the meal content).

Here, the calculation of the blood glucose level measurement start time by the notification system 10 will be specifically described. As described above, the arithmetic processing unit 24 of the blood glucose measurement device 12 is provided with the control-side time setting unit 46 based on the measurement start setting program 40. The control-side time setting unit 46 reads meal time information from the meal time storage area 48 and reads a carbo value corresponding to the meal time information from the meal data storage area 50. At this time, if the carbo values are stored separately for each meal content, all these carbo values are added to obtain the total value of the carbo values. In addition, what is necessary is just to read the value simply, when the carbo value is memorize | stored in the meal data storage area 50 as a total value.

Next, the arithmetic processing unit 24 reads a time amount reference table 58 (lookup table) stored in advance in the database storage area 54. FIG. 6 is a table showing an example of the time amount reference table 58. The amount of time reference table 58 is set with the amount of time to start measuring the blood glucose level corresponding to a predetermined range of the carbo value (total value of one meal), that is, the predicted time when the blood glucose level reaches the peak value after the meal. Yes.

Specifically, in the time amount reference table 58 according to the present embodiment, the predetermined range of the carbo value is divided into three ranges of 3 or less, 3 to 10, 10 or more, and the time amounts corresponding to these three ranges are shown. It has been decided. That is, if the carbo value is 3 or less, the amount of time is 3 hours after eating, if the carbo value is 3 to 10, the amount of time is 2 hours after eating, and if the carbo value is 10 or more, the amount of time is after eating 1 hour. Thus, if the range of the carbo value is classified into about three patterns, the amount of data is reduced, and the processing in the arithmetic processing unit 24 is speeded up. Of course, the time amount reference table 58 is not limited to the table shown in FIG. 6. For example, if the carbo value range is divided into four or more ranges, the measurement start time of the blood sugar level can be more accurately determined. It is also possible to calculate.

The arithmetic processing unit 24 (control-side time setting unit 46) sets the carbo value (total value of one meal) and then starts the measurement of blood glucose level in one meal with reference to the time amount reference table 58. Determine the amount of time. Then, the blood glucose level measurement start time (measurement start time information) is calculated by adding the amount of time to the meal time information read from the meal time storage area 48.

Specifically, for example, when the user selects curry and rice at lunch and finishes eating at 12:30, the user sets (stores) 12:30 as mealtime information in the mealtime storage area 48. Then, 14 (see FIG. 2) is set in the meal data storage area 50 as the carbo value data for one meal. When the two pieces of information (meal time information and information based on the meal content) are input, the arithmetic processing unit 24 starts calculating the blood glucose level measurement start time.

In this case, since the carbo value is 14, referring to the time amount reference table 58 shown in FIG. Then, 1 hour is added to 12:30 read from the meal time storage area 48, and 13:30 is calculated as measurement start time information. The measurement start time information calculated by the arithmetic processing unit 24 is stored in the measurement start time storage area 52. Then, based on the time measurement by the timer 36, when 13:30 (or approaches), the arithmetic processing unit 24 operates the alarm generation unit 34 to generate a predetermined sound (alarm sound) to the blood sugar to the user. Notify that it is the measurement time of the value.

Thus, when the carbo value is as high as 14, it is assumed that the carbohydrate is glycated without taking time, so the blood sugar level rises rapidly and the highest peak value is about 1 hour after meals. Shows the vicinity. The user can measure the blood sugar level in the vicinity of the peak value of the blood sugar level by notifying the start of the blood sugar level measurement one hour after the meal by the notification system 10.

Of course, various methods can be taken when notifying the user of the start of blood glucose measurement based on the set measurement start time. That is, as a notification to the user, when the blood glucose level measurement start time is set by the control side time setting unit 46, the time when the blood glucose level should be measured is displayed on the display panel 16, or the alarm generation unit 34 (speaker) ) To inform the time to measure the blood glucose level by voice. In addition, when the set measurement start time arrives, a sound (alarm sound, voice, or the like) is output by the alarm generation unit 34, or a message indicating that the blood glucose level should be measured is displayed on the display panel 16. . Of course, a plurality of these methods may be combined. In addition, it is displayed on the display panel 16 so that the time is counted down toward the measurement start time, or a small sound is made gradually and loudly about 2 to 3 minutes before the set measurement start time. The notification method may be devised so as to be shifted.

Furthermore, the arithmetic processing unit 24 is configured to automatically stop the power supply of the internal mechanism after setting the measurement start time, and to drive only the arithmetic processing unit 24 and the timer 36 with low power, and to start measurement. The power supply may be automatically restarted when time comes. By comprising in this way, the power consumption of the blood glucose measuring device 12 can be suppressed.

The notification system 10 is basically configured as described above. Next, the operation and effect of the blood glucose measurement device 12 including the notification system 10 will be described. FIG. 7 is a flowchart showing an example of operation processing of the blood glucose measurement device 12 according to the present embodiment.

As shown in FIG. 7, the blood glucose measurement device 12 supplies necessary power to an internal mechanism (for example, the arithmetic processing unit 24) when the user switches on the power supply 28, and performs the above-described notification processing and blood glucose measurement. A start state is entered in which value measurement processing can be performed (step S10).

Next, the arithmetic processing unit 24 displays on the display panel 16 an initial menu for selecting a mode for setting the notification process and a mode for performing the blood glucose level measurement process, and prompts the user to select each mode. (Step S11).

When the mode for setting the notification process is selected by the user in step S11, the arithmetic processing unit 24 causes the display panel 16 to display a time input screen for inputting (setting) mealtime information (step S12). . In this case, the meal time information can be easily set by displaying the current time measured by the timer 36 and inputting the set time so as to shift from the current time. When meal time information is input from the user, the meal time information is stored in the meal time storage area 48 via the meal time setting unit 42.

Next, a screen for confirming whether or not to set blood glucose level measurement start time information is displayed on the display panel 16 (step S13).

When the user sets blood glucose level measurement start time information, an input screen for inputting (setting) the measurement start time information is displayed on the display panel 16 (step S14). When time data (time or amount of time) is input from the user based on this display, it is stored (set) as measurement start time information in the measurement start time storage area 52 via the user time setting unit 47. Of course, the setting of the blood glucose level measurement start time information by the user may be set separately from the present processing flow.

Next, the arithmetic processing unit 24 causes the display panel 16 to display a carbo value input screen for inputting (setting) carbo values (information based on meal contents) (step S15). In this case, the carbo value database 56 is displayed on the carbo value input screen, and the user inputs the carbo value based on the meal contents while referring to this database. In inputting the carbo value, the carbo value is individually input for each meal content, and a plurality of carbo values for each meal content are stored in the meal data storage area 50 via the meal data setting unit 44. At this time, the plurality of carbo values are stored in association with the meal time information. As described above, the total value of the carbo values in one meal may be input by the user.

Next, the arithmetic processing unit 24 (control-side time setting unit 46) reads and adds a plurality of carbo values stored in the meal data storage area 50, and based on the total value of the carbo values, the blood glucose level after the meal The amount of time for which is near the peak value is calculated (step S16). At this time, the time amount reference table 58 stored in the database storage area 54 is read, and the time amount corresponding to the carbo value (total value) is determined with reference to the time amount reference table 58.

Thereafter, the arithmetic processing unit 24 reads the meal time information stored in the meal time storage area 48, adds the amount of time calculated in step S16 to the meal time information, and calculates the measurement start time of the blood sugar level. (Step S17). In this case, by calculating the measurement start time of the blood sugar level as the time, it is possible to easily correspond to the time measured by the timer 36.

Next, the arithmetic processing unit 24 checks whether or not the measurement start time information is stored in the measurement start time storage area 52, that is, whether or not the measurement start time information is set by the user in step S14 (step S18). ). When the measurement start time information is not set, the process proceeds to step S19, and when the measurement start time information is set, the process proceeds to step S20.

In step S19, the blood glucose level measurement start time information calculated in step S17 is stored (set) in the measurement start time storage area 52. Then, the arithmetic processing unit 24 monitors the measurement start time information, and sets so as to generate an alarm when the time of the timer 36 reaches the measurement start time. In this way, by setting the blood glucose level measurement start time (alarm generation), even if the user himself / herself does not set the blood glucose level measurement start time information, if the blood glucose level measurement start time is reached, the alarm generation unit Since 34 notifies, it can avoid that a user forgets the measurement of a blood glucose level.

On the other hand, in step S20, based on the blood glucose level measurement start time information calculated in step S17, the measurement start time information stored in the measurement start time storage area 52 is shifted to obtain new measurement start time information. Store (reset) in the measurement start time storage area 52. For example, when the blood glucose level measurement start time information is set 2 hours after the meal by the user, and the amount of time calculated in step S16 is calculated as 3 hours, it is set to 2 hours previously set by the user. Then, the measurement start time information is reset by performing correction for adding 1 hour. The arithmetic processing unit 24 monitors the measurement start time information, and sets so as to generate an alarm when the time of the timer 36 reaches the measurement start time. Thus, even if the user sets the blood glucose level measurement start time in advance, if the measurement start time is reset based on the total value of the carbo values, the blood glucose level measurement start time can be easily changed (shifted). Thus, the blood glucose level near the peak value can be measured.

When step S19 or S20 is completed, the power supply 28 is partially turned off, and a standby mode in which only the arithmetic processing unit 24 and the timer 36 are driven is performed (step S21). In this standby mode, it is determined whether or not the time measured by the timer 36 has reached the time of the measurement start time information set in step S19 or S20 (step S22).

Then, when the measurement time of the timer 36 reaches the set time of the measurement start time information, the arithmetic processing unit 24 operates the alarm generation unit 34 to generate a predetermined alarm (step S23). Thereby, the blood glucose measuring device 12 can prompt the user to measure the blood glucose level.

After the measurement start time has elapsed, a blood glucose level measurement process is performed by the user, and the measured blood glucose level is stored in the blood glucose level data storage area 38 (step S24). In this case, the blood glucose measurement device 12 may be operated so as to omit steps S10 and S11, and guidance may be given to immediately perform the blood glucose level measurement process. The notification system 10 can prompt the blood sugar measuring device 12 to measure the blood sugar level by the processing flow as described above.

[Application example]
FIG. 8 is a flowchart showing an application example of operation processing during blood glucose measurement of the blood glucose measurement device 12 using the notification system 10 according to the present embodiment.

When the blood glucose level measurement start time (information) is set using the carbo value, the blood glucose measurement device 12 associates (links) a plurality of blood glucose levels (measurement results) measured based on the measurement start time. It can be configured. That is, when the measurement start time is set based on the carbo value, the blood glucose level near the peak value can be measured. Therefore, when blood glucose management is performed by obtaining a plurality of blood glucose levels near the peak value (for example, This is useful information when receiving instructions on meal contents and meal methods from a doctor.

Hereinafter, the processing flow for associating the measurement result when the measurement start time is set based on the carbo value will be described in detail. First, the blood glucose measurement device 12 obtains a blood glucose level measurement result by measuring the blood glucose level by a user operation (step S30).

Next, the arithmetic processing unit 24 determines whether or not a carbo value has been input before measuring the blood glucose level performed by the user (step S31). That is, when a carbo value is input, the blood glucose level measurement start time is set based on the carbo value, and thus the blood glucose level measurement is related to the carbo value. In this case, the process proceeds to step S32. On the other hand, if the carbo value is not input, the blood glucose level measurement is not related to the carbo value. In this case, the process proceeds to step S34.

In step S32, it is determined whether or not the blood glucose level measurement is within ± 30 minutes with respect to the time when the alarm is notified (that is, the set measurement start time). Thereby, it is possible to determine whether or not the blood glucose level has been measured in accordance with the measurement start time set using the carbo value. That is, when the blood glucose level measurement is within ± 30 minutes, it can be seen that the measurement result of the carbo level and the blood glucose level are related to each other. In this case, the process proceeds to step S33. On the other hand, when the blood glucose level measurement is ± 30 minutes or more, it can be considered that the measurement result of the carbo level and the blood glucose level is no longer relevant. In this case, the process proceeds to step S34. The determination of the blood glucose level measurement time is not limited to within ± 30 minutes, and can be set to various ranges such as ± 15 minutes.

In step S33, the measurement result and the carbo value are associated (linked) and stored in the blood glucose level data storage area 38. In addition, a display indicating that the measurement result (blood glucose level) is a measurement based on the carbo value may be added so that the user can check on the display panel 16.

On the other hand, in step S34, the measurement result is simply stored in the blood glucose level data storage area 38.

In this way, by inputting the carbo value and storing the blood glucose level measurement result in association with each other, when transmitting a plurality of blood glucose levels (measurement results) stored in the blood glucose level data storage area 38 as data, For example, only the measurement result linked to the input of the carbo value can be taken out. That is, a doctor who teaches blood glucose management can recognize the peak value (measurement result) of the user's blood sugar level by confirming the measurement result associated with the input of the carbo value. Can be done.

As described above, according to the notification system 10 according to the present embodiment, the measurement start time of the blood glucose level is set using the meal time information and the carbo value, and the measurement start time is notified, thereby performing after the meal. The blood glucose level can be measured near the peak value at which the blood glucose level rises most. In other words, by using the carbo value, it is possible to relatively easily determine the time from the nutrition taken in the meal to the conversion to blood glucose, and predicting the time when the blood glucose level is near the peak value, It is possible to notify. As a result, the user can easily recognize the blood glucose level near the peak value, and can perform blood glucose management well.

Further, by displaying the carbo value database 56 on the display panel 16, the user can easily use the carbo value based on the displayed meal contents. In this case, when the meal data setting unit 44 selects the meal content displayed on the display panel 16 and sets the carbo value of the selected meal content, the user can display the display panel 16 on the display panel 16. The carbo value can be used simply by selecting the contents of the meal. Therefore, the user himself / herself can omit the work of converting the meal contents into the carbo value, and the blood glucose level measurement start time can be set more easily.

Furthermore, if the time amount is set with reference to the time amount reference table 58 in which the blood glucose level measurement start time and the carbo value are associated with each other, the calculation processing unit 24 can more easily set the blood glucose level measurement start time. it can.

Further, in the blood glucose measurement device 12, by storing the blood glucose level measurement start time and the blood glucose level measured within a predetermined time before and after the measurement start time in association with each other, the user or doctor can make a vicinity of the peak value for each meal. Blood glucose level can be recognized, and blood glucose management can be performed more satisfactorily.

It should be noted that the notification system 10 according to the present invention is not limited to the above-described embodiment, and can of course have various configurations without departing from the gist of the present invention. For example, the notification system 10 may calculate the blood glucose level measurement start time using an arithmetic expression or the like without using the time amount reference table 58.
