Hereinafter, the activity amount measuring apparatus according to the present invention, and with the amount of activity measurement system like the preferred embodiment will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the activity amount measuring device 10 is configured as a device (walking measuring device: pedometer) for measuring the amount of activity such as the number of walks, the fast walking time, and the walking intensity of the user 100, for example. The activity amount measuring device 10 is a device that exclusively detects the activity amount of the user 100, and is hereinafter also referred to as an activity amount meter 10. Alternatively, the activity amount measuring device 10 may be attached to another device, and may be applied to a device carried and used by the user 100, for example, a smartphone, a mobile phone, a PDA, a wearable computer, or the like. It is possible.

Further, the activity meter 10 according to the present embodiment is configured to be able to cooperate with the glucose meter 12 for measuring the component amount (blood glucose level) of the glucose component contained in the blood of the user 100. That is, the activity meter 10 and the glucose meter 12 constitute an activity amount measuring system 14 that measures and monitors the activity amount of the user 100 so that the blood glucose level of the user 100 is within an appropriate range based on the blood glucose level of the user 100. doing.

The activity measurement system 14 is configured to enable data communication between the activity meter 10 and the blood glucose meter 12. When the blood glucose level is measured by the blood glucose meter 12, the user 100 performs an operation of transmitting the obtained blood glucose level data GD to the activity meter 10. This makes it possible to use the blood glucose level data GD in the activity meter 10. Hereinafter, the activity amount measuring system 14 will be specifically described.

The blood glucose meter 12 of the activity measurement system 14 is configured as a self-measurement (SMBG: Self Monitoring of Blood Glucose) device in which the user 100 himself / herself measures the blood glucose level, and the measured blood glucose level data GD of the user 100 is used. Make records and calls. The blood glucose meter 12 includes a blood glucose meter main body 16 that is gripped and operated by the user 100. As shown in FIG. 2, the glucose meter main body 16 is provided with an operation unit 18, a notification unit 20, a communication unit 22, a detection unit (measurement unit) 24, a control unit 26, and a storage unit 28.

As shown in FIGS. 1 and 2, the operation unit 18 of the blood glucose meter 12 is composed of a group of operation buttons and the like that the user 100 presses when measuring the blood glucose level or calling the blood glucose level data GD. .. For example, the operation unit 18 has a move button for moving the selection frame displayed on the monitor 20a (notification unit 20), a selection button for selecting or deselecting the function of the item in which the selection frame is located, and a read button for reading the recorded data. , A power button for switching on / off of the blood glucose meter 12 and the like are included. Further, the notification unit 20 is a functional unit that provides the user 100 with information related to the blood glucose level, and includes a monitor 20a composed of a liquid crystal, an organic EL, an LED, etc., and a speaker (not shown) that outputs sound including voice. can give.

The communication unit 22 of the glucose meter 12 is a communication module that performs information communication with an external device by a well-known communication method. Examples of this type of communication method include short-range wireless communication methods such as Bluetooth (registered trademark), ZigBee (registered trademark), wireless LAN, and NFC and RF-ID. Further, for example, the communication unit 22 may be configured to automatically construct a wireless communication line with a predetermined external device (activity meter 10) based on the user 100 bringing the devices close to each other.

Further, the glucose meter 12 may be configured to open a communication line only to a device having a preset access authority in communication with an external device. For example, the communication command includes the device identification code of the activity meter 10 itself, and the blood glucose meter 12 performs data communication with the activity meter 10 by registering the device identification code in advance. Tolerate. The device identification code is pre-registered by a medical worker such as a doctor, and by preventing the user 100 from changing it, it is possible to prevent the blood glucose level information from being leaked to an external device that has not been registered.

The detection unit 24 of the glucose meter 12 performs optical measurement on the blood taken into the chip (not shown) attached to the glucose meter main body 16. Therefore, the detection unit 24 has a light emitting unit and a light receiving unit (not shown), emits measurement light from the light emitting unit to the test paper to which blood in the chip is attached, and detects the reflected light of the test paper by the light receiving unit. .. The method for measuring the blood glucose level is not limited to detection by optical means, and measurement may be performed by, for example, electrical means, magnetic means, or antibody reaction. An example is a glucose meter to which the enzyme electrode method is applied. Further, the blood glucose meter 12 may be configured such that a sensor is inserted under the skin of the user 100 and the blood glucose level is continuously calculated based on the glucose concentration of the interstitial fluid detected by the sensor.

The control unit 26 is configured as an electronic circuit (computer) having an input / output I / F, a processor, and the like (not shown). The storage unit 28 of the glucose meter 12 is connected to or mounted on this electronic circuit. The control unit 26 controls the operation of the entire glucose meter 12 by the processor reading and executing the blood glucose measurement program (not shown) stored in the storage unit 28. For example, the control unit 26 controls the drive of the detection unit 24 to measure the blood glucose level, notifies the measured blood glucose level by the notification unit 20 (monitor 20a or speaker), and notifies the blood glucose level to the storage unit 28. Remember. When the communication unit 22 recognizes the connection of the external device, the control unit 26 transmits the blood glucose level data GD or other information (blood glucose level, etc.) to the external device as needed.

The blood glucose meter 12 has a function of converting the blood glucose level into a plurality of stages so that the user 100 can easily recognize how much (high, low, etc.) the blood glucose level is. That is, as shown in FIG. 3, the control unit 26 sets a plurality of boundary values B (predetermined values) for the parameters of the entire blood glucose level, and sets one blood glucose level between the adjacent boundary values B. For example, in FIG. 3, blood glucose levels classified into hypoglycemia, low, normal, slightly elevated, elevated, and hyperglycemia are set, and the blood glucose level is applied according to the measured blood glucose level.

As shown in FIG. 2, the control unit 26 of the glucose meter 12 has a blood glucose level setting unit 26a, and the boundary value of the blood glucose level is set by the user 100 (including a medical worker such as a doctor in this case). B can be set arbitrarily. For example, the user 100 operates the operation unit 18 of the glucose meter 12, connects an external device to the glucose meter 12 so as to be communicable, and classifies (hypoglycemia, low, normal, slightly high, high, hyperglycemia). Enter the boundary value B that separates. In the illustrated example, the boundary value B between hypoglycemia and low is 73 mg / dL, the boundary value B between low and normal is 100 mg / dL, the boundary value B between normal and slightly high is 116 mg / dL, and the boundary value between slightly high and high is slightly high. B is set to 148 mg / dL, and the boundary value B between high and hyperglycemia is set to 177 mg / dL.

Then, when the blood glucose meter 12 measures the blood glucose level of the user 100, the blood glucose level is added to the obtained blood glucose level data GD, and the blood glucose level is output to the monitor 20a. As a result, the user 100 can easily recognize what the blood glucose level is. As for the blood glucose level, it is preferable that the boundary value B can be set separately before and after a meal. As a result, the blood glucose level measured before the meal and the blood glucose level measured after the meal do not extremely deviate from each other, and the user 100 can satisfactorily recognize the blood glucose level.

This blood glucose level is also shared by the activity meter 10. That is, the activity meter 10 receives and stores the blood glucose level from the blood glucose meter 12, and converts it into the blood glucose level when the blood glucose level data GD measured from the blood glucose meter 12 is transmitted. As a result, the amount of activity can be set based on the blood glucose level that is easy for the user 100 to understand.

Returning to FIG. 1, the activity meter 10 of the activity measurement system 14 has a disk-shaped activity meter main body 30 that the patient carries and operates. The activity meter main body 30 measures the activity amount of the user 100 by being attached to or stored in clothes or the like during the activity of the user 100. In the present embodiment, the walking motion of the user 100 is detected as the amount of activity of the user 100. Therefore, as shown in FIG. 2, an activity sensor 32 for detecting the vibration of the user 100 is provided inside the activity meter 10.

As the activity sensor 32, for example, a 3-axis acceleration sensor capable of detecting vibration during operation of the user 100 on three axes (XYZ axes) orthogonal to each other is used. The configuration of the activity sensor 32 is not particularly limited, and for example, a piezoelectric resistance type, a capacitance type, a heat detection type, or the like can be applied.

In addition to the activity sensor 32, the activity meter 10 is provided with an operation unit 34, a notification unit 36, a communication unit 38, a control unit 40, and a storage unit 41.

As shown in FIG. 1, the operation unit 34 is composed of several operation button groups. The activity meter main body 30 according to the present embodiment is provided with a setting button 34a and a recording button 34b on its side peripheral surface, and has a display switching button 34c on a surface on which a monitor 36a (notifying unit 36) is provided. .. The setting button 34a is used when setting items to be registered in the activity meter 10 (for example, age, gender, height, weight, etc.), when switching between a plurality of modes (setting mode, measurement mode, etc.), and the like.

The record button 34b reads out a record of past activities (number of walks, time of fast walking, walking distance, calories burned, total calories burned, walking intensity, etc.) under the operation of the user 100, and monitors 36a of the notification unit 36. Display on.

The display switching button 34c switches the contents (number of walks, fast walking time, walking distance, calories burned, total calories burned, walking intensity, etc.) displayed on the monitor 36a of the notification unit 36 under the operation of the user 100. For example, each time the display switching button 34c is pressed, the above contents are switched in order.

Further, the notification unit 36 is composed of a monitor 36a, a speaker (not shown), and the like, similarly to the blood glucose meter 12. Further, the communication unit 38 of the activity meter 10 adopts a communication module that adopts the same communication method as the blood glucose meter 12. The communication unit 38 of the activity meter 10 accesses the blood glucose meter 12 and receives various data (blood glucose level data GD and information on the blood glucose level) under the operation of the control unit 40.

Like the glucose meter 12, the control unit 40 of the activity meter 10 is also configured as an electronic circuit (computer) having an input / output I / F, a processor, etc. (not shown), and the storage unit 41 is connected to or mounted on the electronic circuit. Has been done. The control unit 40 controls the operation of the entire activity meter 10 by the processor reading and executing the activity meter program (not shown) stored in the storage unit 41. Specifically, a blood glucose level acquisition unit 42, an activity amount monitoring unit 44, and a setting control unit 46 are constructed inside the control unit 40.

The blood glucose level acquisition unit 42 is a functional unit that controls the operation of the communication unit 38 to acquire the blood glucose level data GD from the blood glucose meter 12. For example, the blood glucose level acquisition unit 42 determines the communicable state of the activity meter 10 and the blood glucose meter 12 based on the radio signal received by the communication unit 38, and sends a plurality of types of transmission commands to the blood glucose meter 12 in the communicable state. Send. Examples of the transmission command include a device identification code, a blood glucose level request command for requesting the blood glucose level data GD from the blood glucose meter 12, and the control unit 40 of the blood glucose meter 12 receives the blood glucose level request command, and the blood glucose level data GD. Is transmitted to the activity meter 10.

The activity amount monitoring unit 44 is a functional unit that receives a detection signal from the activity amount sensor 32 and calculates the activity amount of the user 100. In the measurement of the activity amount, for example, the noise included in the detection signal is removed, and the number of walks is counted from the vibration of each of the three axes of the activity amount sensor 32 accompanying the walking of the user 100. Further, the activity amount monitoring unit 44 measures the vibration time together with the vibration (large vibration) of the user 100 during walking by a timer unit (not shown) to obtain the walking speed, and when the walking speed is equal to or higher than a predetermined speed. Detects that the user 100 is walking fast. A well-known method can be adopted for the detection of this type of gait.

The activity amount monitoring unit 44 measures the time for fast walking and calculates the walking intensity (activity intensity) according to the walking speed. The number of walks, the time for fast walking, the walking intensity, and the like are calculated in predetermined time units (for example, 1 hour, 10 minutes, 2 minutes, etc.). In the present embodiment, a predetermined time unit is set to one hour, but this time unit can be freely designed. Then, the activity monitoring unit 44 links the calculated parameters such as the number of walks, the walking time, and the walking intensity with the date and time measured by the timer unit, and adds them to the actual measurement database 62 (see also FIG. 4B) of the storage unit 41. I will remember.

Here, the activity meter 10 according to the present embodiment uses METs, which are indicators of activity intensity, with respect to walking intensity. The METs are units that fluctuate according to a multiple of the oxygen uptake based on the oxygen uptake in the resting state (sitting state, etc.) of the user 100 (1 MET). For example, taking walking exercise as an example of physical activity, it is about 2 METs when standing, about 3 METs when walking, about 4 METs when walking fast, and about 5 METs when walking fairly fast. The activity monitoring unit 44 digitizes the METs by performing processing such as conversion using a preset function formula based on the measured number of walks and the time of fast walking.

The setting control unit 46 is a functional unit that sets the activity plan of the user 100 when the activity meter 10 is used. The activity meter 10 according to the present embodiment includes a target value for the number of walks, a target value for the fast walking time (hereinafter, the target value for the number of walks and the target value for the fast walking time are collectively referred to as an activity target value AT), and walking. The intensity target value (METs target value MT: intensity target value) can be set in 1-hour units. Therefore, the target setting unit 48 and the METs setting unit 50 are provided in the setting control unit 46.

The setting control unit 46 operates the target setting unit 48 and the METs setting unit 50 when the setting mode is selected under the operation of the operation unit 34 by the user 100. The target setting unit 48 and the METs setting unit 50 raise or lower their respective target values to set them to appropriate values. Specifically, as in the target database 60 shown in FIG. 4A, the user 100 himself inputs the amount of activity based on the daily behavior. For example, the user 100 inputs the activity target value AT and the METs target value MT, which have a large number of walks and a long fast walking time when commuting to work or school, based on his / her own behavior. The target setting unit 48 and the METs setting unit 50 store the activity target value AT and the METs target value MT input by the user 100 in the target database 60 of the storage unit 41 in association with the date and time.

It is preferable that the activity meter 10 has a configuration in which the activity target value AT and the METs target value MT can be set separately during work or holidays of the user 100. Further, the setting control unit 46 may perform a guidance display on the notification unit 36 (monitor 36a) in setting the target value to guide the input of the user 100. Alternatively, the activity meter 10 stores a general target value of the user 100 according to the work form (desk work, outer circumference, etc.) as an initial parameter, and even if the configuration is such that the setting is finely adjusted from the initial parameter. Good.

The activity amount monitoring unit 44 described above measures the activity amount AM (measured value of the number of walks, the measured value of the fast walking time) and the METs measured value MM as shown in FIG. 4B in accordance with the measurement of the activity amount of the user 100. It is stored in the actual measurement database 62 in units of time. In this way, the setting control unit 46 uses the target database 60 and the actual measurement database 62 to compare the activity actual measurement value AM with respect to the activity target value AT and the METs actual measurement value MM with respect to the METs target value MT in a predetermined time unit. It can be easily done.

That is, the activity amount monitoring unit 44 reads out the target database 60 during the measurement of the activity amount, compares the activity actual measurement value AM and the activity target value AT in the time unit, and also compares the METs target value MT and the METs actual measurement in the time unit. Compare the values MM. Then, for example, when the activity actual measurement value AM is less than a predetermined ratio to the activity target value AT, the activity amount monitoring unit 44 presents to review the activity target value AT via the notification unit 36 (inquiry). To do). As a result, the user 100 can review his / her own activity plan and past activities.

As an example, in FIGS. 4A and 4B, the target value of the number of walks is 2000 when the time is around 17:00, while the measured value of the number of walks at 17:50 is 901. Further, while the target value of the fast walking time is 5 minutes, the measured value of the fast walking time is 2 minutes. In this way, when the measured value (the number of walks, either one or both of the fast walking times) is less than 50% of the target value, the activity monitoring unit 44 changes the activity target value AT at 18:00. Inquire (suggest). For example, the activity monitoring unit 44 notifies the user that the target value of the number of walks at 18:00 is 1500 steps, which is half of 3000 steps, and the target value of the fast walking time is 7.5 minutes, which is half of 15 minutes. It is good to do it.

Further, the setting control unit 46 sets activity target values AT and METs targets set by the user 100 based on the blood glucose level data GD acquired from the blood glucose meter 12 in order to reduce the possibility that the user 100 becomes hypoglycemic during activity. The value MT can be maintained or changed. Therefore, a set value determination unit 52 and a tendency monitoring unit 54 are provided inside the setting control unit 46.

The set value determination unit 52 determines the maintenance or change of the activity target value AT and the METs target value MT based on the blood glucose level data GD (blood glucose level converted from the blood glucose level data GD) acquired by the blood glucose level acquisition unit 42. To do. For example, the set value determination unit 52 determines that the activity target value AT and the METs target value MT within a predetermined time from the blood glucose level measurement time are maintained as they are when the blood glucose level is above normal. On the other hand, the set value determination unit 52 determines the change of the activity target value AT and the METs target value MT within a predetermined time from the blood glucose level measurement time when the blood glucose level is low or lower. The set value determination unit 52 may determine the setting of the activity target value AT and the METs target value MT based on the blood glucose level data GD and the threshold value (predetermined value) corresponding thereto.

Upon receiving the change determination of each target value from the set value determination unit 52, the target setting unit 48 and the METs setting unit 50 appropriately change the activity target value AT and the METs target value MT set by the user 100. The details of the changes in this case will be described in detail in a later processing flow.

In addition, the trend monitoring unit 54 monitors the amount of activity during the set period by referring to the amount of activity (actual measurement value AM and METs actual measurement value MM) when the user 100 has hypoglycemia in the past, and the current activity. It is a functional unit that determines whether or not the quantities have similar tendencies. That is, the activity meter 10 linked with the blood glucose meter 12 can memorize the process in which the blood glucose level of the user 100 reaches hypoglycemia by the acquired blood glucose level data GD. Further, the activity meter 10 can also store the activity amount of the user 100 in the process leading to hypoglycemia (may include the METs measured value MM in addition to the activity measured value AM). Therefore, when the activity amount of the user 100 shows a tendency similar to the activity amount that has led to hypoglycemia in the past, the activity meter 10 warns that the user 100 may become hypoglycemic. ..

Specifically, the setting control unit 46 generates a hypoglycemia period database 64 showing the activity of the user 100 at the time of hypoglycemia and a recovery period database 66 showing the activity of the user 100 when the blood glucose level recovers from the hypoglycemia. It has a tendency data generation unit 56.

As shown in FIG. 5, the hypoglycemia period database 64 includes the date and time when the hypoglycemia was reached, the blood glucose level tendency information Gf, the activity amount tendency information Af, and the like. The blood glucose level tendency information Gf is the initial blood glucose level before hypoglycemia, the post-decrease blood glucose level at the time of hypoglycemia, the amount of change from the initial blood glucose level to the post-decrease blood glucose level, and the like. The activity amount tendency information Af is a compilation of the actual activity value AM up to the set period before the time when the hypoglycemia was measured. Examples of this setting period include 3 hours before the time when hypoglycemia is measured.

The tendency data generation unit 56 extracts the blood glucose level tendency information Gf and the activity actual measurement value AM during the set time associated with the blood glucose level when the user 100 becomes hypoglycemic. Further, the tendency data generation unit 56 may generate an average tendency of the hypoglycemic period by calculating an average value for each time during the set time when there is a plurality of information on the hypoglycemic period.

Further, as shown in FIG. 6, the recovery period database 66 also includes the date and time when the blood glucose level is recovered from the hypoglycemia, the blood glucose level tendency information Gf, the activity amount tendency information Af, and the like, similarly to the hypoglycemia period database 64. The blood glucose level tendency information Gf is an initial blood glucose level at the time of hypoglycemia, a post-recovery blood glucose level at the time of recovery from hypoglycemia, a change amount of the post-recovery blood glucose level from the initial blood glucose level, and the like. The activity amount tendency information Af is a summary of the activity measurement value AM from the time when the hypoglycemia level is measured to the time after a predetermined period. Further, the tendency data generation unit 56 may generate an average tendency for the recovery period by calculating an average value for each time during a predetermined period when there is a plurality of information on the recovery period.

When the tendency monitoring unit 54 receives the activity measured value AM from the activity monitoring unit 44, for example, as shown in FIG. 7, the tendency monitoring unit 54 takes out the activity measured value AM (current activity measured value AM1) up to 3 hours ago, and is in the hypoglycemic period. The similarity with the activity amount tendency information Af (or the hypoglycemic period average tendency) of the database 64 is determined. In determining the similarity, it is preferable to calculate the correlation coefficient R between the current activity actual measurement value AM1 and the activity amount tendency information Af by, for example, an appropriate calculation method.

Then, for example, the tendency monitoring unit 54 determines that the similarity is high when the correlation coefficient R is equal to or greater than the comparison value (R ≧ 0.8, etc.), and sets a target for changing the activity target value AT and the METs target value MT. Instruct unit 48. On the other hand, when the correlation coefficient R is less than the comparison value (R <0.8, etc.), the tendency monitoring unit 54 determines that the similarity is low (dissimilarity), and keeps the activity target value AT and the METs target value MT as they are. Make a decision to maintain. The details of the changes in this case will be described in detail in a later processing flow.

The activity meter 10 and the activity measurement system 14 according to the present embodiment are basically configured as described above, and the effects thereof will be described below together with an example of a processing flow.

The activity meter 10 may be used in cooperation with the blood glucose meter 12 (transmission / reception of mutual data) at the time of use, or may be used alone (non-cooperation with the blood glucose meter 12). The case where the activity meter 10 and the blood glucose meter 12 are linked will be described first with reference to FIG. 8A. The activity measuring system 14 wirelessly communicates at the initial stage when the activity meter 10 and the blood glucose meter 12 are linked, or by proximity. Every time it becomes possible, a level-linked process that matches the blood glucose level is performed.

As described above, in the activity measurement system 14, the boundary value B of the blood glucose level of the blood glucose meter 12 is set by the user 100 (step S10). For example, the blood glucose level setting unit 26a of the blood glucose meter 12 stores the boundary value B in the storage unit 28 when the user 100 inputs the boundary value B via the operation unit 18, and the boundary value B is stored when the blood glucose level is measured. The blood glucose level according to the above can be read out.

In the level cooperation process, the user 100 communicates between the devices by bringing the activity meter 10 and the blood glucose meter 12 close to each other, and authenticates the cooperation between the activity meter 10 and the blood glucose meter 12. Specifically, when the activity meter 10 can wirelessly communicate with the blood glucose meter 12 due to proximity, the activity meter 10 transmits an identification command including a device identification code related to access authority to the blood glucose meter 12 (step S11).

When the glucose meter 12 receives the identification command, it determines whether or not the device identification code is pre-registered, and if the device identification code is registered, the activity meter issues a cooperation response command indicating that cooperation is possible. It is transmitted to 10 (step S12). If the device identification code is not registered, a response command that cannot be linked is sent.

Upon receiving the cooperative response command, the activity meter 10 transmits a blood glucose level request command to the blood glucose meter 12 (step S13). The blood glucose level request command may include date and time information when the blood glucose level was transmitted in the past.

When the blood glucose meter 12 receives the blood glucose level request command, it refers to the date and time information and generates transmission information including the blood glucose level at the time of initial access or when the boundary value B of the blood glucose level is changed. Is transmitted to the activity meter 10 (step S14). If the boundary value B of the blood glucose level is not changed, the transmission information indicating that the blood glucose level is the same is transmitted. As a result, the activity meter 10 receives the transmission information from the blood glucose meter 12 and sets (newly registers, updates or maintains) the blood glucose level in the apparatus (step S15).

Next, as shown in FIG. 8B, in the cooperation between the activity meter 10 and the blood glucose meter 12, the activity meter 10 performs a blood glucose level acquisition process for acquiring the blood glucose level data GD from the blood glucose meter 12. Specifically, when the blood glucose meter 12 measures the blood glucose level, it stores the measurement date and time information together with the blood glucose level data GD in the storage unit 41 (step S20). Further, the blood glucose meter 12 displays the blood glucose level data GD stored based on the operation of the user 100 on the monitor 20a.

Then, when the user 100 brings the activity meter 10 and the blood glucose meter 12 close to each other, communication is performed between the devices, and the activity meter 10 has an identification command including a device identification code for the blood glucose meter 12 as in the level linkage process. Is transmitted (step S21). When the glucose meter 12 receives the identification command, it determines whether or not the device identification code is pre-registered, and if the device identification code is registered, the activity meter issues a cooperation response command indicating that cooperation is possible. It is transmitted to 10 (step S22). If the device identification code is not registered, a response command that cannot be linked is sent.

Upon receiving the cooperative response command, the activity meter 10 transmits a blood glucose level data request command to the blood glucose meter 12 (step S23). The blood glucose meter 12 transmits the latest measured blood glucose level data GD to the activity meter 10 when the blood glucose level is being measured (step S24). As a result, the activity meter 10 receives the blood glucose level data GD and stores the blood glucose level data GD in the storage unit 41.

Then, the activity meter 10 uses the received blood glucose level data GD to perform a process of monitoring the activity amount of the user 100 (blood glucose level linkage process) (step S25). As shown in FIG. 8B, the blood glucose level linkage process can be further divided into the latest process and the past trend process. The latest process is a process for monitoring the activity amount and activity intensity of the user 100 corresponding to a time close to the blood glucose level measurement time (for example, within one hour from the blood glucose level measurement time). The past tendency process is a process for monitoring the activity amount and activity intensity of the user 100 by using the past blood glucose level and activity amount. The activity meter 10 automatically performs these processes based on the acquisition of the blood glucose level data GD.

Further, the activity meter 10 also performs a non-cooperative monitoring process for monitoring the activity amount and activity intensity of the user 100 by the activity meter 10 alone without linking with the blood glucose meter 12. The activity measurement system 14 performs this non-cooperative monitoring process even if the activity meter 10 is configured to be able to cooperate with the blood glucose meter 12, for example, when the blood glucose level is not acquired. Next, this non-cooperative monitoring process will be described with reference to FIG.

First, the activity monitoring unit 44 of the activity meter 10 continuously receives the detection signal of the activity sensor 32, and sets the activity measured value AM and the METs measured value MM of the user 100 in units of predetermined time (1 hour). (Step S30).

Then, the set value determination unit 52 of the setting control unit 46 extracts the activity actual measurement value AM for each hour and compares it with the activity target value AT stored in the target database 60 (step S31). As described above, the activity target value AT and the METs target value MT are set by the user 100 himself. Therefore, by comparing the activity target value AT and the activity actual measurement value AM, and the METs target value MT and the METs actual measurement value MM, respectively, it is determined whether or not the target has been achieved, and the ratio at the time of achievement and the ratio at the time of non-achievement is calculated. be able to.

The set value determination unit 52 determines whether or not the activity actual measurement value AM is less than a predetermined ratio (for example, 50%) of the activity target value AT (step S32). Then, when the activity actual measurement value AM is less than 50% of the activity target value AT, the process proceeds to step S33, and when the activity actual measurement value AM is 50% or more of the activity target value AT, the process proceeds to step S35.

In step S33, the target setting unit 48 receives a determination result that the activity actual measurement value AM is less than 50% of the activity target value AT from the set value determination unit 52, and performs a process of inquiring the user 100 to update the activity amount target value. That is, when the activity actual measurement value AM is less than 50% of the activity target value AT, the activity actual measurement value AM of the user 100 does not reach the activity target value AT significantly, so it is better to review the activity target value AT. It can be said that it is good. Therefore, the setting control unit 46 generates notification information as to whether or not to change the activity target value AT and outputs it to the notification unit 36. The user 100 can confirm whether or not the activity target value AT is appropriate based on this notification information.

Further, it is preferable that the activity target value AT to be changed is indicated in the notification information, and the user 100 determines the activity target value AT to be changed and resets the activity target value AT. For example, the activity target value AT to be changed is set to a value such as 80% of the set activity target value AT. Upon receiving the user 100's selection of setting a new activity target value AT or maintaining the current activity target value AT, the setting control unit 46 updates or maintains the activity target value AT for the next time (step S34). As a result, the activity amount monitoring unit 44 monitors the activity amount of the user 100 by comparing the activity target value AT and the activity actual measurement value AM at the next time.

Further, in step S35, the set value determination unit 52 determines whether or not the activity actual measurement value AM is less than a predetermined ratio (for example, 400%) with respect to the activity target value AT. If the activity measured value AM is less than the predetermined ratio of the activity target value AT, the process proceeds to step S36, and if the activity measured value AM is equal to or more than the predetermined ratio of the activity target value AT, the process proceeds to step S37.

In step S36, the target setting unit 48 receives the determination result that the activity actual measurement value AM is less than 400% of the activity target value AT from the set value determination unit 52, and does not change the activity target value AT, that is, the current activity target value AT. To maintain. That is, when the actual activity value AM for the last 1 hour is 50% or more and less than 400%, it can be regarded as an appropriate amount of activity assumed for the activity target value AT set by the user 100. Therefore, the activity amount for the next time is monitored without changing the activity target value AT that has already been set.

On the other hand, in step S37, when the target activity measurement value AM receives a determination result of 400% or more of the activity target value AT from the set value determination unit 52, the target setting unit 48 outputs an exercise excess alert from the notification unit 36. That is, when the activity actual measurement value AM of 400% or more is measured with respect to the activity target value AT set by the user 100, it can be said that the activity target value AT is low or the exercise is excessive and the burden on the body is large. Therefore, by outputting an exercise excess alert, the activity target value AT is changed, or the user 100 is warned to suppress the activity. As a result, the user 100 can immediately review the content of his / her activities.

In the non-cooperative monitoring process, by performing the above processing, the activity amount of the user 100 is monitored so as to meet the target, or the activity target value AT is reset to an appropriate target according to the activity of the user 100. Can be changed.

On the other hand, in the blood glucose level linked processing, the activity meter 10 carries out the latest processing and the past tendency processing as described above. The latest processing is simply the activity target value processing that maintains or changes the activity target value AT from the blood glucose measurement time based on the blood glucose level, and the METs target value MT from the blood glucose measurement time based on the blood glucose level. There is activity intensity target value processing to maintain or change.

First, the activity target value processing (blood glucose level linked processing) will be described with reference to FIG. 10A. In this case, the blood glucose level acquisition unit 42 converts the acquired blood glucose level data GD into a blood glucose level when the above-mentioned blood glucose level acquisition process is performed (step S40). Since the blood glucose level is stored in advance in the storage unit 41, the blood glucose level can be easily obtained by applying the acquired blood glucose level data GD to the blood glucose level.

Then, the setting control unit 46 reviews the activity target value AT set by the user 100 based on the blood glucose level, and maintains or changes the activity target value AT. For example, the set value determination unit 52 determines whether the obtained blood glucose level is above normal or below normal (lower or lower) (step S41). If the blood glucose level is above normal, the process proceeds to step S42, and if the blood glucose level is below normal, the process proceeds to step S43.
It should be noted that the determination of the blood glucose level is not limited to the boundary between normal and low, and for example, the determination of the blood glucose level may be determined to be lower or higher and lower than hypoglycemia.

In step S42, the target setting unit 48 uses the set activity target value AT within a predetermined time after the blood glucose measurement as it is, based on the blood glucose level being above normal. That is, if the blood glucose level is above normal, even if the user 100 performs the activity according to the activity target value AT, there is little possibility that hypoglycemia will occur. Therefore, by maintaining the activity target value AT set by the user 100, the user 100 is encouraged to perform an appropriate activity.

On the other hand, in step S43, the target setting unit 48 performs a process of lowering the activity target value AT within one hour after the set blood glucose measurement based on the blood glucose level being less than normal (lower or lower). .. That is, when the blood glucose level is low or lower, if the user 100 performs an activity in accordance with the activity target value AT, hypoglycemia may occur. Therefore, by lowering the activity target value AT set by the user 100 by a predetermined ratio, the activity of the user 100 is suppressed.

The predetermined time for maintaining or changing the activity target value AT based on the blood glucose level is not particularly limited, and may be performed until, for example, the next blood glucose level is measured. Further, the predetermined rate of lowering the activity target value AT is not particularly limited, and for example, the current activity target value AT may be uniformly set to a value of 50% or less. In addition, the predetermined ratio may change according to the activity target value AT, and when the activity target value AT is set high (5,000 steps or more as an example), the activity target value can be increased by increasing the ratio. The AT may be significantly lowered (for example, 1000 steps). Alternatively, the target setting unit 48 may be changed depending on the blood glucose level. For example, in the case of hypoglycemia, a predetermined ratio may be larger than the ratio at the lower blood glucose level.

On the other hand, as shown in FIG. 10B, in the activity intensity target value processing (blood glucose level linkage processing), when the above-mentioned blood glucose level acquisition processing is performed, the acquired blood glucose level data GD is converted into a blood glucose level (step S50). ..

Then, the METs setting unit 50 reviews the METs target value MT set by the user 100 based on the blood glucose level, and maintains or changes the METs target value MT. For example, the METs setting unit 50 determines whether the obtained blood glucose level is above normal or below normal (lower or lower) (step S51). If the blood glucose level is above normal, the process proceeds to step S52, and if the blood glucose level is below normal, the process proceeds to step S53.

In step S52, the METs setting unit 50 uses the set METs target value MT within a predetermined time after the blood glucose measurement as it is, based on the fact that the blood glucose level is above normal. That is, if the blood glucose level is above normal, there is little possibility that hypoglycemia will occur even if the user 100 performs activities in accordance with the METs target value MT. Therefore, by maintaining the METs target value MT set by the user 100, the user 100 is encouraged to perform an appropriate activity.

On the other hand, in step S53, the METs setting unit 50 performs a process of lowering the METs target value MT within a predetermined time after the set blood glucose measurement based on the blood glucose level being lower than normal. That is, when the blood glucose level is lower or lower, if the user 100 performs an activity in accordance with the METs target value MT, hypoglycemia may occur. Therefore, by lowering the METs target value MT set by the user 100, the activity of the user 100 is suppressed.

In the process of lowering the METs target value MT, for example, the current METs target value MT may be uniformly set to the minimum during activity (METs = 2), or the METs target value MT may be lowered by a predetermined step (for example, one step). Conceivable. Further, the METs setting unit 50 may be lowered according to the METs target value MT, and when the METs target value MT is set high (for example, METs = 5 or more), the METs target value MT may be significantly lowered. Good (for example, METs = 2). Further, the METs setting unit 50 may be changed depending on the blood glucose level. For example, when the blood glucose level is hypoglycemic, the METs target value MT is set, and when the blood glucose level is low, the METs target value MT is higher than the METs target value MT. You should lower it.

Further, when the activity target value AT or the METs target value MT is lowered, the setting control unit 46 asks the user 100 whether or not to reset the activity target value AT or the METs target value MT via the notification unit 36. It is preferable to change the activity target value AT and the METs target value MT under the operation of the user 100. Alternatively, the setting control unit 46 may automatically lower the activity target value AT or the METs target value MT and notify the reset activity target value AT or the METs target value MT.

The above-mentioned activity target value processing and activity intensity target value processing are examples of setting the amount of activity and the intensity of activity based on the blood glucose level. Then, the activity meter 10 according to the present embodiment is a comprehensive management process in which the activity amount monitoring unit 44 monitors the activity amount and the METs in addition to the blood glucose level, and processes both the activity target value AT and the METs target value MT. It is configured to carry out. Next, this comprehensive management process will be described with reference to FIG.

In the comprehensive management process, as in the activity target value process and the activity intensity target value process, first, the acquired blood glucose level data GD is converted into the blood glucose level in accordance with the blood glucose level acquisition process (step S60). Further, the set value determination unit 52 extracts the activity actual measurement value AM at a predetermined time before the blood glucose measurement from the actual measurement database 62 based on the command of the blood glucose level acquisition unit 42 (step S61). In the present embodiment, the predetermined time before the blood glucose measurement is set to 1 hour.

Then, the set value determination unit 52 determines whether or not the blood glucose level is normal or higher and the activity actual measurement value AM reaches 50% or more of the activity target value AT (step S62). If the blood glucose level is above normal and the measured activity value AM has achieved 50% of the activity target value AT, the process proceeds to step S63, and the blood glucose level is below normal or the measured activity value AM is 50 of the activity target value AT. If it is less than%, the process proceeds to step S64.

Here, if the blood glucose level is above normal and the actual activity value AM reaches 50% of the activity target value AT, it is estimated that it is unlikely that the user 100 will reach hypoglycemia even if he / she exercises normally. it can. Therefore, in step S63, the target setting unit 48 and the METs setting unit 50 maintain the activity target value AT and the METs target value MT set by the user 100 as they are.

On the other hand, when the blood glucose level is lower than normal (lower or lower) or the actual activity value AM is less than 50% of the activity target value AT, it is determined in step S64 whether or not the blood glucose level is lower or lower. Then, if the blood glucose level is lower or lower, the process proceeds to step S65, and if the blood glucose level is higher than the lower level (above normal), the process proceeds to step S66.

When the blood glucose level is lower or lower, as described above, if the user 100 performs an activity in accordance with the activity target value AT or the METs target value MT, hypoglycemia may occur. Therefore, in step S65, the target setting unit 48 lowers the activity target value AT to a predetermined ratio (for example, 50%) or less, and the METs setting unit 50 lowers the METs target value MT to a predetermined stage (for example, the lowest level during activity: METs). = 2) is reduced to. As a result, it is possible to promote suppression of activity and reduce the possibility that the user 100 becomes hypoglycemic.

On the other hand, when the blood glucose level is higher than lower (above normal), the activity measured value AM for 1 hour before the blood glucose measurement is equal to or less than a predetermined ratio of the activity target value AT (for example, 50% of the activity target value AT). ), Which means that it has not been achieved. Therefore, in step S66, the setting control unit 46 performs a process of inquiring the user 100 to update the activity target value AT and the METs target value MT via the notification unit 36. As a result, the user 100 recognizes that his / her activity amount is low.

Then, the target setting unit 48 lowers the activity target value AT to a predetermined ratio (for example, 80%) based on the permission operation of the user 100, and also sets the METs target value MT based on the permission operation of the user 100. Lower (step S67). As a result, the user 100 is recommended to perform an appropriate activity based on the changed activity target value AT and METs target value MT. When the user 100 does not allow the change of the activity target value AT or the change of the METs target value MT, the current activity target value AT and the METs target value MT are maintained.

When the activity target value AT and the METs target value MT are set (maintained or changed) in steps S63, S65, and S67, the control unit 40 uses the notification unit 36 to set (maintain or change) the activity target value AT and the METs target value based on the blood glucose level. Notify that the value MT has been set (step S68). Then, the activity monitoring unit 44 can prompt the user 100 to perform an appropriate activity by monitoring the activity measured value AM detected by the activity sensor 32 using the activity target value AT and the METs target value MT. It becomes.

Further, returning to FIG. 8B, the activity meter 10 performs the past trend processing in addition to the latest processing (comprehensive management processing) in the blood glucose level linkage processing. The past tendency processing informs the user 100 of the possibility of hypoglycemia based on the amount of activity in which the user 100 has hypoglycemia in the past. Hereinafter, this past trend processing will be described with reference to FIG.

In the past trend processing, the activity monitoring unit 44 of the activity meter 10 continuously receives the detection signal of the activity sensor 32, and sets the activity measured value AM of the user 100 in a predetermined time unit (1 in the present embodiment). The measurement is performed in units of time (step S70). Then, the activity amount monitoring unit 44 stores the calculated activity actual measurement value AM in the actual measurement database 62 of the storage unit 41.

When the tendency monitoring unit 54 receives an instruction from the activity amount monitoring unit 44 that the activity amount has been updated on an hourly basis, the tendency monitoring unit 54 reads out the hypoglycemic period database 64 and the convalescent period database 66 of the storage unit 41 (step S71).

After that, the trend monitoring unit 54 sets the activity measurement value AM (current activity measurement value AM1) from the present to the past set time before (3 hours ago) and the activity amount tendency information Af (hypoglycemia) of the hypoglycemia period database 64. The similarity with the past activity measured value AM) of the reached set time is compared (step S72). When there are a plurality of hypoglycemic period data, the similarity between the current activity measured value AM1 and the hypoglycemic period average tendency may be compared, or the similarity may be compared for each individual data.

Then, the tendency monitoring unit 54 determines whether or not the current activity actual measurement value AM1 and the activity amount tendency information Af are similar (step S73). For example, when the correlation coefficient R (see FIG. 7) is calculated in step S72, similarity is determined when the correlation coefficient R is equal to or greater than the comparison value (0.8) held in advance, and step S74. Proceed to. On the other hand, the tendency monitoring unit 54 determines the dissimilarity when it is less than the comparison value, skips the subsequent steps, and ends the current past tendency processing.

In step S74, the trend monitoring unit 54 outputs a hypoglycemia alert via the notification unit 36. As a result, when the current activity actual measurement value AM1 and the past activity actual measurement value AM are high and similar, the user 100 can be alerted.

Further, the target setting unit 48 and the METs setting unit 50 change the activity target value AT and the METs target value MT when receiving a high similar determination result from the tendency monitoring unit 54 (step S75). At this time, the tendency monitoring unit 54 analyzes the past activity measured value AM (activity amount tendency information Af of the recovery period database 66) in the recovery period in which the blood glucose level is recovered from hypoglycemia, and sets the target setting unit 48 and METs. The unit 50 may change the activity target value AT and the METs target value MT based on the analysis result.

Specifically, the target setting unit 48 changes the setting of the activity target value AT set by the user 100 to a value of a predetermined ratio (for example, 50%) or less. Further, the METs setting unit 50 changes the setting of the METs target value MT to the lowest level (METs = 2). Further, when the setting is changed, the setting control unit 46 notifies via the notification unit 36 that the activity target value AT and the METs target value MT based on the blood glucose level have been set (step S76).

As described above, the activity meter 10 and the activity measurement system 14 according to the present embodiment set the activity target value AT and the METs target value MT based on the blood glucose level data GD to obtain the blood glucose level for the user 100. It is possible to satisfactorily present the corresponding target value. That is, by recognizing the activity target value AT and the METs target value MT based on the blood glucose level data GD, the user 100 becomes aware of appropriate activities, and as a result, hypoglycemia can be suppressed. .. Therefore, the activity meter 10 can provide higher convenience.

In this case, when the blood glucose level is lower than normal (lower or lower), the activity meter 10 lowers the activity target value AT or METs target value MT set by the user 100, so that the user 100 having a low blood glucose level Can be made to recognize that the activity is suppressed. Further, since the activity target value AT includes the target value of the walking number of the user 100 and the target value of the fast walking time, the activity meter 10 can walk the walking number and the fast walking based on the blood glucose level during the walking exercise of the user 100. The time can be presented well. Further, the activity meter 10 can appropriately present the walking intensity (METs) such as the walking speed during the walking exercise of the user 100 based on the blood glucose level.

Then, when the activity measurement value AM is less than a predetermined ratio of the activity target value AT, the activity meter 10 can make the user 100 recognize its own activity amount by inquiring about the change of the activity target value AT. it can. In addition, the user 100 can make a reasonable activity plan by appropriately changing or maintaining the activity target value AT. Further, the activity meter 10 determines the similarity of the current activity amount by using the activity amount that has become hypoglycemic in the past, thereby suppressing the user 100 from becoming hypoglycemic again during the activity. Can be done. Moreover, the activity meter 10 can easily and quickly promote the improvement of the activity to the user 100 by notifying the alarm that there is a possibility of hypoglycemia.

The present invention is not limited to the above-described embodiment, and various modifications can be made according to the gist of the invention. For example, in the above-described embodiment, an example in which the activity meter 10 and the glucose meter 12 are configured as separate devices has been described. However, the activity measuring system 14 (activity measuring device 10) can integrally configure the activity meter 10 and the blood glucose meter 12 as one device, and for example, the activity meter 10 has a function of measuring the blood glucose level. May be provided.

Further, the configuration according to the present invention is not limited to the walking measurement device that measures the walking of the user 100, and can be applied to the activity amount measuring device 10 that measures various activities. For example, other activity measuring devices include devices for measuring cardiopulmonary function and devices for measuring the amount of exercise of various exercises (measurement devices for abdominal muscles and push-ups, etc.).
