(Functional configuration of control unit 110)
FIG. 5 is a functional configuration diagram centering on the functions of the control unit 110 described above. The control unit 110 includes an intake energy acquisition unit 111, a consumed energy acquisition unit 112, a calculation unit 113, an analysis unit 114, and a generation unit 115.
The intake energy acquisition unit 111 acquires intake calories for meals taken by the user. That is, the intake energy acquisition unit 111 acquires the intake calories from the calorie information 3100 for meal information input by the user from the operation unit 130 in the input mode, and is analyzed by the server 30 in the server mode. The calorie intake is acquired via the communication unit 170. The consumed energy acquisition unit 112 acquires the calorie consumption as the user's consumed energy information from the activity amount measuring unit 120 at regular intervals.

  The calculation unit 113 acquires blood glucose level data input by the user from the operation unit 130, and based on the intake calorie acquired by the intake energy acquisition unit 111 and a predetermined first prediction algorithm, the blood glucose level for the intake calorie A prediction curve (hereinafter referred to as a first prediction curve) that predicts a change in the above is obtained. Further, the calculation unit 113 predicts a change in blood sugar level relative to the calorie consumption based on the calorie consumption acquired by the energy consumption acquisition unit 112 and a predetermined second prediction algorithm (hereinafter, second prediction). (Referred to as a curve).

  Here, calculation of the first prediction curve and the second prediction curve will be described. Fig.6 (a) is a figure which shows an example of the 1st prediction curve in this embodiment. The first prediction curve is obtained based on the calorie intake and the first prediction algorithm. The first prediction curve has a delay period d1, a rising period d2, an equilibrium period d3, and a falling period d4. Hereinafter, an example of a first prediction algorithm for obtaining a blood glucose level curve in each period will be described.

  The delay period d1 indicates a period from the start of a meal until the blood glucose level (reference value) C0 at the start of the meal is exceeded. In the delay period d1, a predetermined time (for example, 15 minutes) from the start of the meal is set, and the blood glucose level C0 at the start of the meal is maintained. Note that the blood glucose level C0 at the start of the meal uses the blood glucose level measured by the user at the time, but if the measurement cannot be made, for example, a preset standard value of the user's blood glucose level is used. May be.

The rising period d2 indicates a period starting from the end of the delay period d1 until the blood sugar level starts to rise and reaches a peak value (peak value). The peak value is a value obtained by adding the blood sugar level increase h11 to the blood sugar level C0 at the start of the meal, with the blood sugar level increasing at the slope s1.
The blood glucose level increase amount h11 is obtained, for example, by h11 = (calorie intake) × (insulin secretion amount) × (coefficient α). In the present embodiment, the insulin secretion amount and the coefficient α (> 0) are fixed values set in advance according to the user. The insulin secretion amount and the coefficient may be not only fixed values set in advance, but also values or variable values determined according to user attributes (age, sex, height, weight).

  The equilibrium period d3 is a period in which the blood sugar level is maintained at the peak value from the end of the rising period d2, and in this embodiment, a predefined fixed value is set. In addition, for example, the value obtained by multiplying the calorie intake by a coefficient specific to the user is divided by a coefficient corresponding to the difference from the previous calorie intake, and the equilibrium period using the calorie intake and a predetermined arithmetic expression d3 may be obtained.

  The falling period d4 indicates a period from the end of the equilibrium period d3 until the blood sugar level starts to decrease at the slope s2 and reaches the reference value. That is, the descent period d4 is a period until the blood glucose level returns from the peak value to the reference value (blood glucose level C0 at the start of the meal). The slope s2 is obtained by, for example, s2 = (calorie intake) × (coefficient β). In the present embodiment, the coefficient β is a fixed value (<0) that is predetermined according to the user, but is a value or variable value that is predetermined according to the user's attributes (age, sex, height, weight). It may be.

  Next, the second prediction curve will be described. FIG. 6B is a diagram illustrating an example of the second prediction curve in the present embodiment. The second prediction curve is obtained based on the calorie consumption and the second prediction algorithm. The second prediction curve includes a delay period e1 and a falling period e2. Hereinafter, an example of the 2nd prediction algorithm which calculates | requires the blood glucose level curve in each period is demonstrated.

  The delay period e1 indicates a period from the start of exercise until the blood sugar level starts to decrease, and is a period during which the blood sugar level at the start of exercise is maintained. In the present embodiment, a predetermined period (for example, 2 minutes) is set as the delay period e1. The falling period e2 is a period during which the blood sugar level falls with a slope s3 (the amount of decrease in blood sugar level per unit time Δc) from the end of the delay period e1.

  The amount of decrease Δc is obtained, for example, by Δc = (calorie consumption) × (insulin secretion amount) × (coefficient γ). The calorie consumption is the user's calorie consumption measured by the activity amount measuring unit 120. In the present embodiment, the user's calorie consumption is calculated by the activity amount measuring unit 120 even during normal operation when the user is not conscious of exercise. Calculated and sequentially input. The amount of insulin secretion is a fixed value preset according to the user, and the coefficient γ (<0) may be a variable value according to the blood glucose level, or a fixed value determined according to the user's attribute It may be.

  Returning to FIG. 5, the description will be continued. The analysis unit 114 extracts the user information 200 using the extraction condition for extracting the user information 200 corresponding to the meal information input from the operation unit 130, and uses the extracted user information 200 for the user's blood glucose level for the meal information Analyze value changes. Specifically, for example, when the input meal information is Japanese food A, the next action (meal or exercise) from the time when the Japanese food A is ingested as a waveform representing a change in blood glucose level when the Japanese food A is ingested. Waveform data for a period until it is performed is extracted. In the example of the blood glucose level information 200a shown in FIG. 3A, the waveform data for the period from the time when the breakfast on February 1, 2010 is ingested until the next action, that is, walking is extracted. If walking is not performed, waveform data for a period from when breakfast is consumed until lunch is extracted is extracted. In this way, a waveform representing a change in blood glucose level when the same meal content is ingested is extracted as the first model waveform. In addition, when a plurality of waveforms are extracted, the analysis unit 114 performs processing such as averaging the plurality of extracted waveforms, and generates a first model waveform indicating a change tendency of the blood sugar level with respect to the meal information. To do.

  Further, the analysis unit 114 extracts the user information 200 using the extraction condition for extracting the user information 200 corresponding to the exercise information input from the operation unit 130, and uses the extracted user information 200 for the user for the exercise information. Analyzes changes in blood glucose levels. In the present embodiment, the calorie consumption of the user is sequentially calculated by the activity amount measuring unit 120, but it is distinguished what operation the calculated calorie consumption is performed. Therefore, for an exercise other than the normal operation, the exercise type is input before the user exercises.

  Specifically, for example, when the input exercise information is walking, a waveform representing a change in blood glucose level when walking is performed as a waveform representing a change in blood glucose level in 2010 in the blood glucose level information 200a shown in FIG. Waveform data is extracted from the start of walking on the 1st month until the next action, that is, taking a snack. In this way, a waveform representing a change in blood glucose level when the same exercise is performed is extracted as the second model waveform. In addition, when a plurality of waveforms are extracted, the analysis unit 114 performs processing such as averaging the plurality of extracted waveforms, and generates a second model waveform indicating a blood glucose level change tendency with respect to the exercise information. Generate.

  The generation unit 115 deforms the first prediction curve and the second prediction curve calculated by the calculation unit 113 based on the analysis result of the analysis unit 114, and integrates the deformed first prediction curve and the second prediction curve. Generate a predictive blood glucose curve. Specifically, the generation unit 115 compares the amount of increase h11 up to the peak value of the blood glucose level during the increase period d2 of the first prediction curve with the amount of increase up to the peak value of the first model waveform, and When the difference is equal to or greater than a predetermined threshold, the coefficient α is adjusted so that the increase amount h11 of the first prediction curve becomes the increase amount of the first model waveform. Further, the generation unit 115 compares the equilibrium period d3 of the first prediction curve with the continuation period in which the peak value of the blood sugar level continues in the first model waveform, and the difference between the equilibrium period d3 and the continuation period is determined in advance. If it is equal to or greater than the threshold, the equilibrium period d3 is set so that the equilibrium period d3 of the first prediction curve matches the duration. In the first model waveform, it is assumed that the peak value continues during the period in which the peak value of the blood sugar level falls within the predetermined threshold value Δcth, and continues when the peak value falls below the threshold value Δcth. Judged as the end of the period.

  In addition, the generation unit 115 compares the amount of decrease (h11) in which the blood sugar level has decreased from the peak value in the falling period d4 of the first prediction curve with the amount of decrease in which the blood sugar level has decreased from the peak value of the first model waveform. When the difference in the amount of decrease is equal to or greater than a predetermined threshold, the coefficient β of the slope s2 is set so that the amount of decrease (h11) in the decrease period d4 of the first prediction curve becomes the amount of decrease in the first model waveform. adjust.

  The generation unit 115 deforms the second prediction curve in the same manner as the first prediction curve. Specifically, the generation unit 115 compares the decrease amount Δc per unit time of the blood glucose level in the falling period e2 of the second prediction curve with the decrease amount per unit time of the blood glucose level in the second model waveform, When the difference in the amount of decrease is equal to or greater than a predetermined threshold, the coefficient γ is adjusted so that the amount of decrease Δc of the second prediction curve becomes the amount of decrease in the second model waveform. The generation unit 115 deforms the first prediction curve and the second prediction curve as described above, generates a predicted blood glucose level curve that integrates the deformed first prediction curve and the second prediction curve, and generates the generated prediction. The blood glucose level curve is output to the display unit 150.

  In the present embodiment, the process of deforming the prediction curve based on the analysis result is to extract a parameter indicating the feature quantity of the user's blood glucose level change from the waveform (model waveform) based on the analysis result, (1 prediction curve, second prediction curve) is a process of extracting a parameter corresponding to this feature amount and bringing the prediction curve parameter closer to the analysis result parameter.

The functional configuration of the control unit 110 in the present embodiment is as described above. Returning to FIG. 2, the server 30 according to the present embodiment will be described.
(Server 30)
As illustrated in FIG. 2, the server 30 includes a control unit 310, a communication unit 320, and a storage unit 330. The control unit 310 includes a CPU, a ROM, and a RAM, and a function that performs processing related to the SNS service and a function that performs processing related to the analysis service by executing a control program stored in the ROM in advance using the RAM as a working area. Is executed to control each unit connected to the control unit 310. The process related to the SNS service is a process of transmitting a WEB page related to the SNS service, that is, a WEB page (input screen information) constituting an input screen for inputting a diary in response to a request from a user registered in advance. In addition, a process of receiving data input on a diary input screen or the like and storing it in the server 30 is included. In addition, the process related to the analysis service is based on the data transmitted from the blood sugar level prediction device 10 of the user who uses the SNS service, and specifies the calorie intake for the meal estimated to have been ingested by the user. Is transmitted to the blood glucose level prediction device 10 of the user. Details of the processing related to the analysis service will be described later.

  The communication unit 320 is connected to the communication line 20 and communicates with the blood glucose level prediction device 10 of the user who uses the SNS service under the control of the control unit 310 to transmit and receive data. The storage unit 330 is configured by a storage medium such as a hard disk, and stores a database such as accumulated information 331. Details of the accumulated information 331 will be described later.

  Next, the functional configuration of the control unit 110 of the server 30 will be described. FIG. 7 shows a functional configuration diagram centering on the control unit 110. The control unit 110 includes a reception data analysis unit 311, a data extraction unit 312, and a calorie identification unit 313.

  The received data analysis unit 311 performs morphological analysis and structural analysis on data (hereinafter referred to as diary data) received by the communication unit 340 for an input screen (hereinafter referred to as diary input screen) of a user's diary using the analysis service. Or a character string that matches a character string (hereinafter referred to as an extraction target character string) such as a food name, a dish name, or a menu that is defined in advance as a character string to be extracted. The character string is extracted as information relating to the meal consumed by the user (hereinafter referred to as intake information).

  Note that the extraction target character strings are stored in advance in a food database (not shown) in the storage unit 330 in units of groups indicating food classifications. For example, “Beef Curry”, “Chicken Curry”, “Vegetable Curry”, etc. are remembered as the “Curry and Rice” group, and “Soy sauce Ramen”, “Miso Ramen”, “Salt” as the “Ramen” group. "Ramen" etc. are memorized. In this embodiment, the standard calorie corresponding to the extraction target character string is also stored in the food database. The diary data includes a user ID for identifying a user who has transmitted the diary data, time information, and diary contents.

  The data extraction unit 312 extracts information about calories (hereinafter referred to as calorie information) corresponding to the intake information extracted by the reception data analysis unit 311 from the accumulated information 331 and sends it to the calorie identification unit 313. Here, the accumulation information 331 will be described. The accumulated information 331 includes service user information 331a shown in FIG. 8A and user input information 331b shown in FIG. 8B.

  The service user information 331a includes a user ID uniquely given to a user who uses the SNS service, a user name of the user, and an analysis target indicating whether the user is a use target of the analysis service (1: Analysis target person, 0: non-analysis target person), and attribute information (gender, age, height, weight, hobbies, ...) of the user are stored in association with each other. Each record of the service user information 331a is registered when the user starts using the SNS service. Further, the user input information 331b stores a user ID for each user, a date (time) when the user inputs data on the diary input screen, and content data indicating the content of the diary in association with each other. In this example, the content data mainly includes information about meals eaten by the user, but also includes data other than meals.

  For example, when “ramen” is extracted as ingestion information from the analysis target user's diary data, the data extraction unit 312 extracts calories corresponding to “ramen” from the content data of the user input information 331b. In this example, the character string “ramen” is included in the record 3310 of the user ID 102 and the record 3311 of the user ID 121. As a calorie corresponding to “ramen”, the record 3311 includes a character string “700 kcal”, but the record 3310 does not include a character string indicating calorie. Therefore, in this case, “700 kcal” of the user ID 121 is extracted as the calorie for the intake information “ramen”.

  In addition, since the intake information is an example of “ramen”, calories corresponding to “soy sauce ramen” are extracted. For example, when the intake information is “Miso ramen”, the data extraction unit 312 In the input information 331b, if there is a character string that completely matches the character string of the intake information, calories for that character string are extracted. If there is no completely matched character string, the user inputs the calories for the character string that matches the extraction target character string in the “ramen” group to which “Miso Ramen” belongs in the food database (not shown) in the storage unit 330. Extracted from information 331b.

  As a result of the analysis processing of the received data analysis unit 311, the data extraction unit 312 includes a character string indicating the position of the character string and a calorie consisting of a character string of “kcal” and the character string in the sentence including the character string of the intake information When the positional relationship with the position (hereinafter referred to as calorie data) satisfies a predetermined relationship (for example, the calorie is located within several bits from the last character string of the intake information), the calorie The user ID and the calorie data associated with the content data including the data are extracted as calorie information.

Returning to FIG. 7, the description will be continued. The calorie specifying unit 313 specifies calories corresponding to the intake information in the diary data based on the calorie information extracted by the data extracting unit 312, and sends the specified calories to the communication unit 340 as the intake calorie information for the diary data. .
For example, in the above example, when “700 kcal” of the user ID 102 is extracted as the calorie information, the attribute information of the user of the user ID 102 matches the attribute information of the analysis target user under certain conditions. The calorie information is specified using the calorie information of the user ID 102. The condition that the attribute information matches may be, for example, a condition that calorie information that matches the gender of the attribute information of the analysis target user is used, and the difference from the age of the user is within a predetermined threshold. It is good also as conditions on using calorie information. Moreover, it is good also considering using the calorie information whose difference with the BMI value of the analysis object user calculated using height and weight is within a predetermined threshold, or combining a plurality of conditions. Good.

When there are a plurality of pieces of calorie information that matches the attribute information of the analysis target user, the calorie specifying unit 313 specifies the average, intermediate value, mode, etc. of the calorie data of the calorie information as calories for the intake information. In addition, when there is no calorie information that matches the attribute information, the calorie specifying unit 313 specifies the average value, the intermediate value, the mode value, and the like of the calorie data of the extracted calorie information as the calories for the intake information of the received data. To do. Moreover, the calorie specific | specification part 313 specifies the calorie with respect to intake information from a food database (not shown), if calorie information is not extracted.
As described above, in this embodiment, calorie data for the intake information of the analysis target user is extracted from the content data of the diary, and the calorie data of other users having attribute information with content close to the attribute information of the analysis target user is used. The calorie with respect to the ingestion information of the analysis target user is specified.

The functional configuration of the control unit 310 of the server 30 according to the present embodiment is as described above. Next, the operation of the blood sugar level prediction system 1 will be described.
(Operation)
FIG. 9 shows an operation flow showing the overall operation of the blood glucose level prediction apparatus 10 in the present embodiment. In the following description of the operation, an example will be described in which the user B in the service user information 331a in FIG. 8A acquires ingested calorie information from the server 30 using the SNS service. Further, it is assumed that an input mode is set in advance in the storage unit 140 as an intake energy acquisition mode in the blood sugar level prediction apparatus 10.

When the user B performs an operation of switching the acquisition mode to the server mode via the operation unit 130 (step S100: YES), the control unit 110 changes the input mode stored in the storage unit 140 to the server mode. (Step S200). If the user B does not perform an operation for switching to the server mode (step S100: NO), the control unit 110 performs the process of step S300.
The user B inputs data obtained by actually measuring the blood glucose level once a day via the operation unit 130 of the blood glucose level prediction apparatus 10. When control unit 110 accepts the blood glucose level data and the input time input via operation unit 130, control unit 110 sets the input blood glucose level data as reference value C0, and starts blood glucose level prediction processing (step S300).
The control unit 110 performs a process of calculating the first prediction curve using the reference value C0 input in step S300 and the intake energy information acquired in the server mode set in the storage unit 140 (step S400). ).

  Here, the process of acquiring the intake energy in the server mode will be described using the operation flow of the blood sugar level predicting device 10 and the server 30. FIG. 10 is an operation flow showing an intake energy acquisition process in the blood glucose level prediction apparatus 10 in the server mode. As described above, in the case of the server mode, the user B acquires the intake energy information from the server 30 using the diary data input when using the SNS service. The user B accesses the SNS service WEB site of the server 30 using the blood sugar level predicting apparatus 10 and inputs the meal contents he / she eats on the diary input screen.

When the URL of the SNS service WEB site provided by the server 30 is input via the operation unit 130, the control unit 110 accesses the SNS service WEB site via the communication unit 170 (step S111).
When the user B performs an operation of inputting the user ID “102” via the operation unit 130 on the SNS service WEB site, the control unit 110 inputs the input user ID “102” via the communication unit 170. It transmits to the server 30 and receives a response from the server 30 that permits login to the WEB site and logs in to the WEB site (step S112).
When the user B designates a WEB page indicating his / her diary input screen set in advance in the SNS service via the operation unit 130, the control unit 110 designates the WEB page designated via the communication unit 170 as the server 30. Are displayed on the display unit 150 (step S113). FIG. 11A shows an example of a diary input screen displayed on the display unit 150. In this example, on the diary input screen, the input date 151, the input field 152 for inputting the diary content data, the OK button 153 for instructing to transmit the diary data to the server 30, and the deletion without transmitting the input data. A cancel button 154 for instructing to do so is displayed.
As shown in FIG. 11B, the user B inputs data related to a meal he / she eats and other data through the operation unit 130 in the input field 152, and performs an operation of pressing an OK button 153. The control unit 110 transmits the diary data input on the diary input screen to the server 30 via the communication unit 170 (step S114). And the control part 110 receives the intake calorie information with respect to the diary data transmitted in step S114 from the server 30 during access to a SNS service (step S115). Note that if the intake calorie information cannot be received from the server 30 while accessing the SNS service, the controller 110 may receive the intake calorie information from the server 30 the next time the SNS service is accessed.

Here, an operation of the calorie intake analysis service for the diary data transmitted from the blood glucose level prediction apparatus 10 in the server 30 will be described. FIG. 12 is a diagram showing an operation flow showing the processing of the analysis service of the server 30.
When the control unit 310 receives the diary data transmitted from the blood glucose level prediction device 10 of the user B via the communication unit 320 (step S311: YES), the user input information in the storage unit 330 is shown in FIG. In 331b, as the record 3320 corresponding to the user ID “102”, the reception time and the content data are accumulated, and the analysis target of the service user information 331a is referred to and whether or not the user B is the analysis target person is determined. Judgment is made (step S312).
Since “1” is stored as the analysis target of the user B in the user input information 331b, the control unit 310 determines that the user B is the analysis target (step S312: YES), and the received diary data An analysis process is performed, and it is determined whether or not ingestion information matching the extraction target character string defined in the food database in the storage unit 330 is included in the diary data (step S313). The control unit 310 determines that the character string of “curry” that matches the character string to be extracted is included in the diary data (step S313: YES), and extracts the character string of “curry” as intake information (step S313). S314).
The control unit 310 determines whether or not the user input information 331b in the storage unit 330 includes data including the character string of the intake information “curry” extracted in step S314 (step S315). In the user input information 331b illustrated in FIG. 13, the control unit 310 includes a character string “curry” in each content data of the record 3321 corresponding to the user ID 101, the record 3322 corresponding to the user ID 120, and the record 3323. (Step S315: YES), it is determined whether or not these contents data include calorie data corresponding to “curry” (step S316).
The control unit 310 determines that the calorie data “750 kcal” and “600 kcal” are included after the character string “curry” in the contents data of the records 3321 and 3322 (step S316: YES). The calorie data included in the respective content data 3321 and the record 3322 and the user ID associated with the content data are extracted as calorie information (step S317).
The control unit 310 specifies calories for the ingestion information “curry” of the user B using the calorie information of the user having attribute information that matches the attribute information of the user B among the calorie information extracted in step S317 (step S31). S318).

  In this embodiment, calorie information of a user who matches the sex of the attribute information of the user B and whose difference from the age of the user B is less than 5 years old is used. In this example, the sex of the user B is “male” and the age is “38”. Of the calorie information extracted in step S317, the sex of the user A corresponding to the user ID 101 is “male” and the age is “35”, and the sex of the user C corresponding to the user ID 120 is “female”, age Is “34”. Therefore, in this case, the calorie data “750 kcal” of the calorie information of the user A that matches the sex and age of the user B is specified as the calorie for the ingestion information of the user B. In this example, there is only one calorie information that matches the attribute information of the user B. However, when there are a plurality of calorie information, the average value of the calorie data included in the plurality of calorie information is calculated. It is specified as a calorie for the intake information of the user B.

  In addition, the control unit 310 estimates the time when the ingestion information “curry” is ingested in the diary data of the user B received at step S311 (step S319). For example, when a sentence including a character string indicating intake information includes a predetermined character string (breakfast, lunch, dinner, etc.) indicating the intake timing of a meal, the date of reception of the diary data and the character string are If the character string indicating the intake timing is not included, the time when the diary data is received is estimated as the intake time.

  In this example, as shown in the record 3320 in FIG. 13, in the sentence including the character string of the intake information “curry”, the character string “lunch” is included before the character string “curry”. Unit 310 generates intake calorie information in which intake time information “lunch”, intake information “curry”, and calorie “750 kcal” corresponding to the intake information specified in step S318 are associated with each other via communication unit 320. The ingested calorie information is transmitted to the blood glucose level prediction device 10 of the user B (step S320).

Note that in step S311, the control unit 310 does not receive diary data from the user via the communication unit 320 (step S311: NO), or in step S312, the user who transmitted the diary data is subject to analysis. If it is not a person (step S312: NO), or if intake information is not included in the diary data in step S313 (step S313: NO), the process ends.
Also, in step S315, when the user input information 331b does not store data including the character string of the intake information (step S315: NO), or when it is determined in step S316 that calorie data is not included (Step S316: NO), the control unit 110 extracts the calorie corresponding to the intake information from the food database in the storage unit 330, and specifies the calorie corresponding to the intake information (Step S321). When the intake information is a character string representing a food group, the calories of the food contained in the group are extracted. In this case, the average value of the calories in the group is specified as the calories corresponding to the intake information.

  The processing of the analysis service of the server 30 is as described above. Returning to FIG. 10, the description of the operation of the blood sugar level prediction apparatus 10 will be continued. Control unit 110 calculates a first prediction curve based on the calorie intake information received from server 30 in step S115 (step S116). That is, the control unit 110 calculates the first prediction curve based on the intake information “curry” and the calorie “750 kcal” included in the intake calorie information at the time corresponding to the date included in the intake calorie information and the intake timing “lunch”. To do. In addition, when the intake time information includes the intake timing “lunch”, a preset lunch time (for example, 12:00 pm) is applied as the time corresponding to lunch, and “breakfast” is included. If it is, apply a preset breakfast time (for example, 8:00 am) as the time corresponding to breakfast, and if “dinner” is included, the time corresponding to dinner is set in advance Apply dinner time (eg 8pm).

  The control part 110 calculates the 1st prediction curve based on the calorie contained in intake calorie information about the blood glucose level in lunch time using the 1st prediction algorithm, for example, the 1st prediction curve shown in Drawing 14 (a). Is generated. In addition, the control unit 110 extracts user information 200 corresponding to the intake information “curry” included in the intake calorie information received in step S115, analyzes past blood glucose level changes with respect to the intake information, and generates a first model waveform. Generate (step S117). Specifically, the control unit 110 extracts waveform data until the next action when “curry” is ingested in the waveform of the blood sugar level information 200a, and averages the extracted waveform data, for example, A first model waveform shown in FIG. 14B is generated. If the blood glucose level information 200a does not include a waveform when the same meal content as the intake information is ingested, the process ends without performing the first model waveform generation process.

  The control unit 110 deforms the first prediction curve generated in step S116 based on the first model waveform generated as the analysis result in step S117 (step S118). Specifically, the control unit 110 increases the blood sugar level increase amount h11 in the rising period d2 of the first prediction curve shown in FIG. 14A and the blood sugar level rise of the first model waveform shown in FIG. The amount h21 (C4-C1) is compared, and if the difference in the amount of increase is equal to or greater than the threshold, the first prediction algorithm is set so that the amount of increase h11 in the first prediction curve is h21 (C4-C1). The coefficient α at is adjusted. In addition, after t2 when the blood sugar level of the first model waveform reaches the peak, the control unit 110 performs the duration d31 (t3−t2) from the peak value to t3 within the threshold Δcth range, and the first prediction curve. Is compared with the equilibrium period d3. When the difference between the continuation period d31 and the equilibrium period d3 is greater than or equal to the threshold value, the control unit 110 sets the continuation period d31 as the equilibrium period d3. In addition, the control unit 110 compares the amount of decrease in blood glucose level (h12) in the descending period d4 of the first prediction curve with the amount of decrease in blood glucose level h22 (C4-C2) of the first model waveform. When the difference is greater than or equal to the threshold, the coefficient β in the first prediction algorithm is adjusted so that the amount of decrease h12 becomes the amount of decrease h22 in the first model waveform. FIG. 14C shows the result of deforming the first prediction curve based on the first model waveform in this way.

  The calculation process of the 1st prediction curve in this embodiment is as above. Returning to FIG. 9, the description will be continued. The control part 110 performs the process which calculates a 2nd prediction curve based on the consumption energy measured in the active mass measurement part 120, and the exercise | movement information input by the user B (step S500).

  Here, details of the second prediction curve calculation processing will be described according to the operation flow of FIG. The control unit 110 receives, as energy consumption information, the user's calorie consumption measured at regular intervals by the activity amount measurement unit 120 from the activity amount measurement unit 120 (step S131), and a second prediction curve for the received calorie consumption. Calculation is performed using the second prediction algorithm, and a second prediction curve illustrated in FIG. 16A is generated (step S132).

  When the user performs an operation for displaying an exercise information input screen (not shown) via the operation unit 130, the control unit 110 displays the exercise type information 3200 on the display unit 150 and accepts an input from the user (step S133). ). When the exercise type is input by the user via the operation unit 130 as the exercise information (step S133: YES), the control unit 110 stores the input exercise information in the user information 200 and also adds the input exercise information to the exercise information. Corresponding user information 200 is extracted, a past blood glucose level change with respect to exercise information is analyzed, and a second model waveform is generated (step S134).

  For example, if the input exercise information is the exercise type “3” and the exercise content “walking”, in the example of the blood glucose level information 200a in FIG. 3A, “walking” was performed on February 1, 2010 Waveform data for the period from the start of walking until the next action “snack” is ingested is extracted. In this way, the control unit 110 extracts and averages the waveform data when “walking” is performed from the blood glucose level information 200a, and generates the second model waveform shown in FIG. If the waveform when the same exercise as the exercise information is not included in the blood glucose level information 200a, the process is terminated without generating the second model waveform.

  The control unit 110 transforms the second prediction curve generated in step S132 based on the second model waveform generated as the analysis result in step S134 (step S135). Specifically, the control unit 110 reduces the blood glucose level decrease Δc during the falling period e2 of the second prediction curve shown in FIG. 16A and the blood glucose level reduction of the second model waveform shown in FIG. The quantity Δc1 is compared. The amount of decrease Δc1 of the second model waveform is the amount of decrease per unit time T0 when the blood glucose level decreases by h31 from the blood glucose level at the start of exercise between times t1 and t2. When the difference in the amount of decrease per unit time T0 is equal to or larger than the threshold, the control unit 110 adjusts the coefficient γ in the second prediction algorithm so that Δc in the second prediction curve becomes Δc1. FIG. 16C shows the result of deforming the second prediction curve based on the second model waveform in this way.

  The calculation process of the second prediction curve in the present embodiment is as described above. Returning to FIG. 9, the description will be continued. The control unit 110 generates a predictive blood sugar level curve in which the first predictive curve generated in step S400 and the second predictive curve generated in step S500 are integrated along the same time axis, and the generated predictive blood sugar level curve is generated. The displayed image is displayed on the display unit 150 (step S600).

When the intake energy acquisition mode is the input mode, in the blood sugar level prediction apparatus 10, the control unit 110 displays an input screen (not shown) for inputting meal timing and meal content on the display unit 150, Data input for these items is accepted via the operation unit 130. When the user performs a meal timing input operation, the control unit 110 reads out meal timing data in the meal timing information 3300 in the storage unit 140 and displays the meal timing data on the display unit 150. Accept. When the user performs an operation for inputting meal contents, the control unit 110 reads out meal menu data in the calorie information 3100 in the storage unit 140 and displays the meal menu data on the display unit 150. Accept.
The control unit 110 identifies the calorie intake for the meal content input in the input mode from the calorie information 3100, stores the meal information including the specified intake calorie, the input intake timing and the meal content in the user information 200, and Using the meal information, the same processing as in steps S116 to S118 of FIG. 10 described above is performed, and a first prediction curve based on the intake energy is calculated.

  In this embodiment, when the user uses the SNS service, other users stored in the server 30 that provides the SNS service can enter other information stored in the server 30 that provides the SNS service by inputting ingestion information regarding the meal that he / she has consumed. The calorie corresponding to the intake information is specified from the written diary data. For this reason, even if the user does not input the content of the meal ingested by the blood sugar level prediction device 10, the calorie intake information necessary for predicting the blood sugar level by writing the intake information on the diary input screen provided by the SNS service. And the accuracy of blood glucose level prediction can be improved as compared with the case where there is no calorie intake data necessary for blood glucose level prediction.

  Moreover, the calorie specified in the server 30 is specified based on the calorie ingested by the user who matches the attribute information of the user to be analyzed under a certain condition. For example, even if the same menu is consumed by men and women, the amount of intake (such as large servings) of the menu may differ between men and women. Therefore, the data written by the user whose attribute information matches to some extent is likely to reflect the tendency of the user to be analyzed to eat, and blood glucose level suitable for the user can be predicted.

  In the example of the present embodiment, the user input information 331b is an example in which calorie data is not included in the diary data input in the past by the user who is the target of blood sugar level prediction. If the diary data includes intake information and calorie data, the user's calorie data may be prioritized and included in the user's calorie data and other user's input data. The calorie data to be extracted may be extracted.

<Modification>

Environmental information includes information that indicates where the user to be analyzed has eaten (for example, store name, address, telephone number, etc.), information that indicates other users who have eaten together with the user to be analyzed (user name, etc.) ) Etc. In the case of environment information representing other users, it is a condition that the user is using the same service as the SNS service used by the analysis target user. Relationship information indicating other users having a relationship is stored.

  If the analysis target user sends the diary data sent to the server 30, for example, if the sentence “I ate a hamburger at Y store at dinner” is included in the diary data, the control unit 310 of the server 30 The data is analyzed, and “XX Hamburg” is extracted as intake information, and “Y store” is extracted as environmental information indicating a place. Then, the control unit 310 extracts input data including the intake information “XX Hamburg” from the user input information 331b, and extracts input data including the environmental information “Y store” from the extracted data. . The controller 310 extracts the calorie information for “XX Hamburg” from the extracted input data, extracts the calorie information of the user that matches the attribute information of the user to be analyzed from the extracted calorie information, and the calorie information Is used to identify the calorie for “XX Hamburg”. If there is no content data including environmental information, the calorie is specified based on intake information and user attribute information, as in the embodiment.

  In addition, if the diary data transmitted to the server 30 by the analysis target user includes, for example, the sentence “I ate chicken curry with user A today”, the control unit of the server 30 310 analyzes the diary data and extracts “chicken curry” as intake information and environmental information “user A” representing other users. Then, the control unit 310 extracts input data including the intake information “chicken curry” in the user input information 331b. In addition, the control unit 310 refers to the relationship information of the analysis target user and determines whether “user A” is included. If “user A” is included in the relational information, the diary data of “user A” is extracted from the extracted data, and the diary data of user A corresponding to the received date of the analysis target user's diary data is extracted. When the calorie data for the intake information is included, the calorie data is specified as the calorie for the “chicken curry”. When there is no user A's diary data corresponding to the reception date of the analysis target user's diary data, or when calorie data is not included, the control unit 310, as in the embodiment, The calorie is specified based on the attribute information.

The intake information may be transmitted to the server 30, and the calorie corresponding to the intake information may be specified by the server 30. In this case, the control unit 110 of the blood sugar level predicting apparatus 10 accumulates schedule data in which the schedule content input using the schedule function and the time information of the schedule are combined in a predetermined area of the storage unit 140. The control unit 110 determines whether or not intake information is included in the schedule data every time the schedule data is input. When the intake information is included, the control unit 110 accesses the server 30 when the user uses the SNS service or whenever the schedule data is input, and the intake information A request for specifying the calorie is transmitted to the server 30.

  In response to the request transmitted from the blood sugar level predicting device 10, the server 30 specifies calories for the intake information by the same method as in the embodiment, and transmits calorie information indicating the specified calories to the blood sugar level predicting device 10. The blood glucose level prediction apparatus 10 calculates a first prediction curve based on calorie information transmitted from the server 30, time information of schedule data including the intake information, and the intake information, and predicts a blood glucose level.
