  BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the activity measurement device, the activity measurement system, and the blood glucose meter according to the present invention will be described below in detail with reference to the accompanying drawings.

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

  Further, the activity meter 10 according to the present embodiment is configured to be able to cooperate with the blood glucose meter 12 that measures the component amount (blood sugar level) of the glucose component contained in the blood of the user 100. That is, the activity meter 10 and the blood glucose meter 12 configure the 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 falls within the appropriate range based on the blood glucose level of the user 100 doing.

  The activity measurement system 14 configures the activity meter 10 and the blood glucose meter 12 in data communication. When the user 100 measures the blood glucose level with 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. As a result, the blood glucose level data GD can be used in the activity meter 10. Hereinafter, the activity measurement system 14 will be specifically described.

  The blood glucose meter 12 of the activity measurement system 14 is configured as a device for self measurement (SMBG: Self Monitoring of Blood Glucose) in which the user 100 itself measures the blood glucose level, and the blood glucose level data GD of the measured user 100 is measured. Record and make calls. The blood glucose meter 12 includes a blood glucose meter main body 16 operated by the user 100 for gripping. As shown in FIG. 2, the blood 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 constituted by an operation button group or the like pressed by the user 100 at the time of measuring the blood glucose level or calling out the blood glucose level data GD. . For example, the operation unit 18 is 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. Further, the notification unit 20 is a functional unit that provides the user 100 with information related to the blood glucose level, and has a monitor 20a configured of liquid crystal, organic EL, LED, etc., and a speaker (not shown) that outputs sound including sound. can give.

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

  Furthermore, the blood glucose meter 12 may be configured to open the communication line only to the device having the access right set in advance in communication with the external device. For example, the communication command includes the device identification code of the activity meter 10 itself, and the blood glucose meter 12 communicates data with the activity meter 10 by the device identification code being registered in advance. Tolerate. Pre-registration of the device identification code is performed by a medical worker such as a doctor, and the user 100 can not change it, so that information on the blood glucose level can be prevented from leaking out to an external device that has not been registered.

  The detection unit 24 of the blood glucose meter 12 performs an optical measurement on the blood taken in a chip (not shown) attached to the blood glucose meter main body 16. For this reason, 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 adheres, and detects the reflected light of the test paper by the light receiving unit. . In addition, the measuring method of a blood glucose level is not limited to the detection by an optical means, For example, you may measure by the means by an electrical means, a magnetic means, and an antibody reaction. An example is a blood glucose meter to which the enzyme electrode method is applied. Further, as the blood glucose meter 12, a sensor may be inserted subcutaneously in the user 100, and the blood glucose level may be 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 (not shown), a processor, and the like. The storage unit 28 of the blood glucose meter 12 is connected to or mounted on this electronic circuit. The control unit 26 controls the overall operation of the blood glucose meter 12 by the processor reading out and executing a 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, reports the measured blood glucose level by the notification unit 20 (the monitor 20 a or the speaker), and stores the blood glucose level in the storage unit 28. Remember. Further, when the connection of the external device is recognized by the communication unit 22, the control unit 26 transmits the blood glucose level data GD or other information (blood sugar level etc.) to the external device as necessary.

  Then, the blood glucose meter 12 has a function of converting into a plurality of blood glucose level levels so that it can be easily recognized (high, low, etc.) the blood glucose level measured by the user 100. 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 between adjacent boundary values B as one blood glucose level. For example, in FIG. 3, blood glucose levels divided into hypoglycemia, low, normal, slightly high, and high, 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 blood glucose meter 12 has a blood glucose level setting unit 26a, and the user 100 (in this case, a medical worker such as a doctor is included) is a boundary value of the blood glucose level. B can be set arbitrarily. For example, the user 100 operates the operation unit 18 of the blood glucose meter 12, communicably connects an external device to the blood glucose meter 12, and the like to classify (low blood sugar, low, normal, slightly high, high, high blood sugar) Enter the boundary value B that separates. In the illustrated example, low blood sugar and low boundary value B 73 mg / dL, low and normal boundary value B 100 mg / dL, normal and slightly high boundary value B 116 mg / dL, somewhat high and high boundary value B is set to 148 mg / dL and boundary value B for high and high blood glucose 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 12 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 how much his / her blood glucose level is. In addition, it is preferable that the blood glucose level can set the boundary value B separately before and after a meal. As a result, the user 100 can well recognize the blood glucose level without the extreme divergence between the blood glucose level measured before the meal and the blood glucose level measured after the meal.

  This blood glucose level is also shared in 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 the blood glucose level data GD measured from the blood glucose meter 12 into the blood glucose level when it is transmitted. As a result, the activity amount 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 disc-shaped activity meter main body 30 which the patient carries and operates. The activity meter main body 30 measures the amount of activity of the user 100 by being attached to or stored in clothes or the like at the time of 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 amount sensor 32 for detecting the vibration of the user 100 is provided inside the activity meter 10.

  As the activity amount sensor 32, for example, a three-axis acceleration sensor capable of detecting vibrations during operation of the user 100 in three axes (XYZ axes) orthogonal to each other is used. In addition, the structure of the active mass sensor 32 is not specifically limited, For example, it is possible to apply structures, such as a piezoresistive type, an electrostatic capacitance type, a heat detection type.

  In addition to the activity amount sensor 32, the activity amount 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 configured by 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 circumferential surface, and has a display switching button 34c on the surface on which the monitor 36a (informing unit 36) is provided. . The setting button 34a is used, for example, when switching a plurality of modes (setting mode, measurement mode, etc.) when setting items to be registered in the activity meter 10 (eg, age, sex, height, weight, etc.).

  The record button 34 b reads the record of the past activity (the number of walks, the time of early walk, the walk distance, the consumed calories, the total consumed calories, the walk intensity, etc.) under the operation of the user 100, and the monitor 36 a of the notification unit 36 Display on

  The display switching button 34 c switches the content (the number of walks, the time of early walking, the walking distance, the calorie consumption, the total calorie consumption, the walking intensity, etc.) displayed on the monitor 36 a 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, similarly to the blood glucose meter 12, the notification unit 36 includes a monitor 36a, a speaker (not shown), and the like. Further, the communication unit 38 of the activity meter 10 employs 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 under the operation of the control unit 40 to receive various data (blood sugar level data GD and information on the blood sugar level).

  The control unit 40 of the activity meter 10 is also configured as an electronic circuit (computer) having an input / output I / F (not shown), a processor, etc., as in the blood glucose meter 12, and the storage unit 41 is connected or mounted to this electronic circuit. It is done. The control unit 40 controls the overall operation of the activity meter 10 by the processor reading and executing an activity meter program (not shown) stored in the storage unit 41. In detail, a blood sugar level acquiring unit 42, an activity amount monitoring unit 44, and a setting control unit 46 are built in the control unit 40.

  The blood glucose level acquisition unit 42 is a functional unit that controls the operation of the communication unit 38 and acquires the blood glucose level data GD from the blood glucose meter 12. For example, the blood sugar level acquiring 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 transmits plural types of transmission commands to the blood glucose meter 12 in the communicable state. Send. The transmission command includes a device identification code, a blood glucose level request command for requesting the blood glucose level data GD to the blood glucose meter 12, and the control unit 40 of the blood glucose meter 12 receives the blood glucose level request command. To the activity meter 10.

  The activity amount monitoring unit 44 is a functional unit that receives the detection signal from the activity amount sensor 32 and calculates the activity amount of the user 100. In the measurement of the amount of activity, for example, 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 amount-of-activity sensor 32 as the user 100 walks. In addition, the activity monitoring unit 44 measures the vibration time as well as the vibration (large vibration) of the user 100 while walking by the timer unit (not shown) to obtain the walking speed, and the walking speed is equal to or higher than a predetermined speed. To detect that the user 100 is walking early. The detection of this kind of walking can adopt a well-known method.

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

  Here, the activity meter 10 according to the present embodiment uses METs, which is an index of activity intensity, regarding the walking intensity. The METs are units that change according to a multiple of oxygen uptake based on oxygen uptake in a resting state (such as sitting state) of the user 100 (based on 1 MET). For example, if walking exercise is taken as an example of physical activity, it will be about 2 METs in the standing state, about 3 METs in the walking state, about 4 METs in the early walking, and about 5 METs in the relatively early walking. The activity amount monitoring unit 44 digitizes the METs by performing processing such as conversion using, for example, a previously-set functional expression, based on the measured number of walks and the time of early walking.

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

  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 and lower each target value and set the target value to an appropriate value. Specifically, as in the target database 60 shown in FIG. 4A, the user 100 itself inputs an activity amount based on the action of one day. For example, the user 100 inputs an activity target value AT and a METs target value MT, which have a large number of walks or long walk times at commuting time or school, based on their own actions. 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 be configured to be able to separately set the activity target value AT and the METs target value MT separately for the work and holidays of the user 100. Further, the setting control unit 46 may display guidance on the notification unit 36 (monitor 36 a) 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 type of work (desk work, outer circumference, etc.) as an initial parameter, and even if the setting is finely adjusted from the initial parameter Good.

  The above-described activity monitoring unit 44 measures the activity measurement value AM (the measurement value of the number of walks, the measurement value of the fast walking time) and the METs measurement value MM as shown in FIG. It stores in the measurement database 62 in units of time. As described above, the setting control unit 46 uses the target database 60 and the actual measurement database 62 to compare the actual activity value AM with the activity target value AT and the actual METs value MM with the METs target value MT in predetermined time units. It becomes easy to do.

  That is, the activity amount monitoring unit 44 reads the target database 60 while measuring the activity amount, compares the activity actual value AM in the time unit with the activity target value AT, and measures the METs target value MT in the time unit and the METs actual value Compare the values MM. Then, for example, when the activity actual value AM is less than a predetermined ratio with respect to the activity target value AT, the activity amount monitoring unit 44 presents the activity target value AT to be reviewed via the notification unit 36 (inquiry To do). This enables the user 100 to review his or her activity plan and past activities.

  As an example, in FIG. 4A and FIG. 4B, while the target value of the number of walks is 2000 when the time is 17 o'clock, the actual number of walks at 17:50 is 901. Also, while the target value for the early walking time is 5 minutes, the measured value for the early walking time is 2 minutes. As described above, the activity monitoring unit 44 changes the activity target value AT at 18 o'clock when the measured value (the number of walks, early walking time, or both) is less than 50% of the target value. Inquire (suggest) For example, the activity amount monitoring unit 44 informs the user that the target value for the number of walks in the 18:00 range be 1,500 steps of half of 3,000 steps, and the target value of early walking time be 7.5 minutes of half fifteen minutes. It is good to do.

  Further, the setting control unit 46 sets an activity target value AT and a METs target 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 of the user 100 becoming hypoglycemic at the time of activity. The value MT can be maintained or changed. For this reason, a setting value determination unit 52 and a trend monitoring unit 54 are provided inside the setting control unit 46.

  The set value determination unit 52 determines 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. Do. For example, when the blood glucose level is above normal, the set value determination unit 52 determines to maintain the activity target value AT and the METs target value MT within a predetermined time from the blood glucose level measurement time as it is. On the other hand, when the blood glucose level is lower than or equal to the set value determining unit 52, the set value determining 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. The setting 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 a threshold value (predetermined value) corresponding thereto.

  When the target setting unit 48 and the METs setting unit 50 receive the change determination of each target value from the setting value determination unit 52, the target setting unit 48 and the METs target value MT set by the user 100 are appropriately changed. The contents of the change in this case will be described in detail in the subsequent processing flow.

  In addition, the trend monitoring unit 54 monitors the amount of activity in the setting period with reference to the amount of activity (measured value of AM and measured value of METs MM) when the user 100 has become hypoglycemic in the past, and the current activity It is a functional unit that determines whether the quantities tend to be similar. That is, the activity meter 10 linked with the blood glucose meter 12 can store the process in which the blood glucose level of the user 100 has reached hypoglycemia based on the acquired blood glucose level data GD. In addition, the activity meter 10 can additionally store the amount of activity of the user 100 (which may include the METs actual measurement value MM in addition to the actual activity measurement value AM) in the process leading to hypoglycemia. Therefore, when the activity amount of the user 100 shows a tendency similar to the activity amount that led to hypoglycemia in the past, the activity amount meter 10 warns that the user 100 may become hypoglycemic. .

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

  As shown in FIG. 5, the hypoglycemic period database 64 includes the date and time when hypoglycemia was reached, the blood glucose level trend information Gf, the activity amount trend information Af, and the like. The blood glucose level trend information Gf includes an initial blood glucose level before hypoglycemia, a post-drop blood glucose level when hypoglycemia occurs, and an amount of change from the initial blood glucose level to the post-drop blood glucose level. The activity amount trend information Af is a summary of the actual activity values AM up to the setting period before the time when hypoglycemia was measured. The setting period may be, for example, three hours before the time of measurement of hypoglycemia.

  The trend data generation unit 56 extracts blood glucose level trend information Gf and an activity measurement value AM during a set time associated with the blood glucose level when the user 100 becomes hypoglycemic. In addition, when there is a plurality of pieces of information on the hypoglycemic period, the tendency data generation unit 56 may calculate the average value at every time during the set time to generate the hypoglycemic period average tendency.

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

  When the trend monitoring unit 54 receives the actual measurement value AM from the active amount monitoring unit 44, for example, as shown in FIG. 7, it extracts the actual measurement value AM (current activity measurement value AM1) up to three hours ago, and The similarity with the activity amount tendency information Af (or the hypoglycemic mean tendency) of the database 64 is determined. In the determination of the similarity, for example, the correlation coefficient R between the current activity actual measurement value AM1 and the activity tendency information Af may be calculated by an appropriate calculation method.

  Then, for example, the trend monitoring unit 54 determines that the similarity is high when the correlation coefficient R is equal to or more than the comparison value (R ≧ 0.8 or the like), and changes the activity target value AT and the METs target value MT as a target setting. Instruct the unit 48. On the other hand, when the correlation coefficient R is less than the comparison value (R <0.8 etc.), the trend monitoring unit 54 determines that the similarity is low (dissimilarity), and the activity target value AT and the METs target value MT are left unchanged. Make a decision to maintain. The contents of the change in this case will be described in detail in the subsequent 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 operation and effects thereof will be described below along with an example of the processing flow.

  The activity meter 10 may be used in cooperation with the blood glucose meter 12 (sending and receiving data mutually) at the time of use, and may be used by the activity meter 10 alone (in a non-cooperation with the blood glucose meter 12). The case where the activity meter 10 and the blood glucose meter 12 cooperate will be described first with reference to FIG. 8A. The active mass measurement system 14 performs wireless communication at the initial stage of linking the activity meter 10 and the blood glucose meter 12 or by proximity. Whenever possible, perform level coordination processing to match the blood sugar level.

  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, when the user 100 inputs the boundary value B via the operation unit 18, the blood glucose level setting unit 26a of the blood glucose meter 12 stores the boundary value B in the storage unit 28, and the boundary value B is measured when measuring the blood glucose level. It makes it possible to read out the blood sugar level according to.

  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 the cooperation between the activity meter 10 and the blood glucose meter 12 is authenticated. 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 the access authority to the blood glucose meter 12 (step S11).

  When the blood glucose meter 12 receives the identification command, it determines whether or not the device identification code is pre-registered, and when the device identification code is registered, the coordinated response command indicating that the cooperation is possible is an activity meter It transmits to 10 (step S12). When the device identification code is not registered, a response command incapable of cooperation is transmitted.

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

  When receiving the blood glucose level request command, the blood glucose meter 12 refers to the date and time information, and generates transmission information including the blood glucose level when the initial access time or the boundary value B of the blood glucose level is changed. And transmits to the activity meter 10 (step S14). In addition, when there is no change of boundary value B of a blood glucose level, transmission information to the effect that blood glucose level is the same is transmitted. Thereby, 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 device (step S15).

  Next, as shown in FIG. 8B, in cooperation between the activity meter 10 and the blood glucose meter 12, the blood glucose level acquisition processing is performed in which the activity meter 10 acquires the blood glucose level data GD from the blood glucose meter 12. Specifically, when the blood glucose level 12 is measured, the blood glucose meter 12 associates the measurement date and time information with the blood glucose level data GD and stores it in the storage unit 41 (step S20). The blood glucose meter 12 also displays the blood glucose level data GD stored based on the operation of the user 100 on the monitor 20 a.

  Then, communication between the devices is performed by bringing the activity meter 10 and the blood glucose meter 12 close to each other by the user 100, and the activity amount meter 10 performs the identification command including the device identification code to the blood glucose meter 12 as in the level cooperation processing. Is sent (step S21). When the blood glucose meter 12 receives the identification command, it determines whether or not the device identification code is pre-registered, and when the device identification code is registered, the coordinated response command indicating that the cooperation is possible is an activity meter It transmits to 10 (step S22). When the device identification code is not registered, a response command incapable of cooperation is transmitted.

  When the activity meter 10 receives the cooperation response command, the activity meter 10 transmits a blood glucose level data request command to the blood glucose meter 12 (step S23). When the blood glucose level is being measured, the blood glucose meter 12 transmits the latest measured blood glucose level data GD to the activity meter 10 (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 performs a process (blood sugar level cooperation process) of monitoring the amount of activity of the user 100 using the received blood sugar level data GD (step S25). The blood sugar level cooperation process can be further divided into the latest process and the past tendency process as shown in FIG. 8B. The latest process is a process for monitoring the amount of activity of the user 100 and the intensity of the activity corresponding to the time close to the measurement time of the blood glucose level (for example, within one hour from the blood sugar level measurement time). The past trend process is a process for monitoring the amount of activity and the intensity of activity of the user 100 by using the past blood glucose level and the amount of activity. The activity meter 10 automatically executes these processes based on the acquisition of the blood glucose level data GD.

  Further, the activity meter 10 performs non-cooperation monitoring processing for monitoring the amount of activity and the intensity of activity of the user 100 even in the activity meter 10 alone without linking with the blood glucose meter 12. The activity amount measurement system 14 performs this non-cooperation monitoring process, for example, when the blood glucose level is not obtained even if the activity meter 10 is configured to be able to cooperate with the blood glucose meter 12. Next, this non-cooperation 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 measures the activity measurement value AM and the METs actual measurement value MM of the user 100 in predetermined time (one hour) units. The measurement is made at step S30.

  Then, the set value determination unit 52 of the setting control unit 46 extracts the actually measured activity value AM for each hour, and compares it with the target activity 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 itself. Therefore, by comparing the activity target value AT with the activity actual measurement value AM, and the METs target value MT with the METs actual measurement value MM, it is determined whether the target has been achieved or not achieved, and the ratio when achieved or not achieved is calculated. be able to.

  The set value determination unit 52 determines whether the actual activity value AM is less than a predetermined ratio (for example, 50%) of the target activity value AT (step S32). Then, if the actual activity value AM is less than 50% of the activity target value AT, the process proceeds to step S33, and if the actual activity 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 the determination result that the actual measurement value AM is less than 50% of the target activity value AT from the setting value determination unit 52, and inquires the user 100 about updating the target activity value. In other words, if the actual measured value AM is less than 50% of the target value AT, the actual value AM of the user 100 does not reach the target value AT largely, so it is better to review the 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 the notification information to the notification unit 36. The user 100 can check whether the activity target value AT is appropriate based on the notification information.

  In addition, it is preferable that the activity target value AT scheduled to be changed is indicated in the notification information, and the user 100 determines the activity target value AT scheduled to be changed, and resets the activity target value AT. For example, the activity target value AT scheduled to be changed is set to a value such as 80% of the set activity target value AT. When the setting control unit 46 receives the setting of a new activity target value AT or the selection of the user 100 for 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). Accordingly, the activity amount monitoring unit 44 monitors the activity amount of the user 100 by comparing the activity target value AT of the next time and the activity actual measurement value AM.

  Further, in step S35, the set value determination unit 52 determines whether the measured activity value AM is less than a predetermined ratio (for example, 400%) with respect to the target activity value AT. If the actual activity value AM is less than the predetermined ratio of the activity target value AT, the process proceeds to step S36. If the actual activity 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 of the activity actual value AM being 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. Maintain. That is, in the case where the actual activity value AM of the latest one hour is 50% or more and less than 400%, it can be considered as a moderate activity amount assumed for the activity target value AT set by the user 100. Therefore, the amount of activity for the next time is monitored without changing the previously set activity target value AT.

  On the other hand, in step S37, the target setting unit 48 outputs an exercise excess alert from the notification unit 36 when the actual measurement value AM receives a determination result of 400% or more of the target activity value AT from the setting value determination unit 52. That is, when the activity 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 load is heavy with excessive exercise. Therefore, by outputting an exercise excess alert, the activity target value AT is changed, or the user 100 is warned to suppress the activity. Thereby, the user 100 can immediately review his / her activity content.

  The non-collaborative monitoring process performs the above processing to monitor the activity amount of the user 100 in line with the target, or resets the activity target value AT, to an appropriate target according to the activity of the user 100. It can be changed.

  On the other hand, in the blood sugar level cooperation process, the activity meter 10 performs the latest process and the past tendency process as described above. The latest processing is simply an activity target value processing for maintaining or changing the activity target value AT from the blood glucose level measurement time based on the blood glucose level, and the METs target value MT from the blood glucose level measurement time based on the blood glucose level There is activity intensity target value processing to maintain or change.

  First, the activity target value process (blood sugar level cooperation process) will be described with reference to FIG. 10A. In this case, when the above-described blood sugar level acquiring process is performed, the blood sugar level acquiring unit 42 converts the acquired blood sugar level data GD into a blood sugar level (step S40). Since the blood sugar level is stored in advance in the storage unit 41, the blood sugar level can be easily obtained by applying the obtained blood sugar level data GD to the blood sugar 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 setting value determination unit 52 determines whether the obtained blood glucose level is higher than normal or lower than normal (lower than or equal to) (step S41). If the blood glucose level is higher than the normal level, the process proceeds to step S42. If the blood glucose level is lower than the normal level, the process proceeds to step S43.
Note that the determination of the blood glucose level is not limited to the boundary between the normal and lower levels, of course. For example, it may be determined that the blood glucose level is lower than or equal to lower blood glucose.

  In step S42, the target setting unit 48 uses the target activity value AT within a predetermined time after measurement of the set blood sugar level as it is, based on the fact that the blood sugar level is equal to or higher than normal. That is, if the blood glucose level is equal to or higher than a normal level, there is little possibility that hypoglycemia will occur even if the user 100 performs an activity in accordance with the activity target value AT. Therefore, by maintaining the activity target value AT defined by the user 100, the user 100 is urged to perform an appropriate activity.

  On the other hand, in step S43, the target setting unit 48 performs processing to lower the activity target value AT within one hour after the set blood sugar level measurement based on the fact that the blood sugar level is lower than normal (lower). . That is, when the blood glucose level is lower than or equal to the blood glucose level, if the user 100 performs an activity in accordance with the activity target value AT, hypoglycemia may occur. Therefore, the activity target value AT set by the user 100 is reduced by a predetermined ratio to promote suppression of the activity of the user 100.

  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, for example, until the next blood glucose level is measured. Further, the predetermined ratio for lowering the activity target value AT is not particularly limited, and it is conceivable to uniformly set the current activity target value AT to a value of 50% or less, for example. In addition, the predetermined ratio may change according to the activity target value AT, and when the activity target value AT is set high (for example, 5000 steps or more as an example), the activity target value is increased by increasing the ratio. The AT may be lowered significantly (one step is taken as an example). Alternatively, the target setting unit 48 may change depending on the blood glucose level, and for example, in the case of hypoglycemia, the predetermined rate may be set larger than the rate in the lower blood glucose level.

  On the other hand, as shown in FIG. 10B, in the activity intensity target value process (blood sugar level cooperation process), when the above-described blood sugar level acquisition process is performed, the acquired blood sugar level data GD is converted to the blood sugar 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) (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 METs target value MT within a predetermined time after measurement of the set blood sugar level as it is based on the fact that the blood sugar level is equal to or higher than normal. That is, if the blood glucose level is above normal, even if the user 100 performs activities in accordance with the METs target value MT, the possibility of hypoglycemia is low. Therefore, by maintaining the METs target value MT defined by the user 100, the user 100 is urged to perform appropriate activities.

  On the other hand, in step S53, the METs setting unit 50 performs processing to lower the METs target value MT within a predetermined time after the set blood sugar level measurement, based on the fact that the blood sugar level is lower than normal. That is, if the blood glucose level is lower than or equal to the user's 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, it is possible to promote suppression of the activity of the user 100.

  In the process of lowering the METs target value MT, for example, the current METs target value MT may be uniformly made the lowest at the time of activity (METs = 2) or the METs target value MT may be lowered by a predetermined level (for example, one level). Conceivable. Also, the METs setting unit 50 may lower according to the METs target value MT, and when the METs target value MT is set high (for example, METs = 5 or more), even if the METs target value MT is significantly lowered. Good (eg, let's say METs = 2). Furthermore, the METs setting unit 50 may change depending on the blood glucose level, for example, when the blood glucose level is hypoglycemia, the METs target value MT is lower than the METs target value MT when the blood glucose level is lower. You should lower it.

  Further, the setting control unit 46 notifies the user 100 whether to reset the activity target value AT or the METs target value MT via the notification unit 36 when lowering the activity target value AT or the METs target value MT. And change the activity target value AT or 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 activity target value AT or the METs target value MT that has been set again.

  The above-described activity target value processing and activity intensity target value processing are an example of setting the amount of activity and the intensity of activity based on the blood sugar level. And the active mass meter 10 which concerns on this embodiment monitors the active mass and METs by the active mass monitoring part 44 other than a blood glucose level, and comprehensive management processing which processes activity target value AT and METs target value MT together It is the structure to carry out. Next, this general management process will be described with reference to FIG.

  In the general management process, similarly to the activity target value process and the activity intensity target value process, the acquired blood glucose level data GD is first converted to a blood glucose level along with the blood glucose level acquisition process (step S60). Further, based on the command from the blood sugar level acquiring unit 42, the setting value judging unit 52 extracts the activity measurement value AM of a predetermined time before the blood sugar level measurement from the actual measurement database 62 (step S61). In the present embodiment, the predetermined time before the blood sugar level measurement is one hour.

  Then, the set value determination unit 52 determines whether the blood glucose level is above normal and the actual measured value AM has achieved 50% or more of the target activity value AT (step S62). If the blood glucose level is above normal and the actual value AM of activity achieves 50% of the target activity AT, the process proceeds to step S63, and the level of blood glucose lower than normal or the actual value AM of activity is 50 the target activity AT. If it is less than%, the process proceeds to step S64.

  Here, in the case where the blood glucose level is above normal and the actual measurement value AM achieves 50% of the target activity value AT, it is presumed that the possibility of reaching low blood sugar is low even if the user 100 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, if the blood glucose level is lower than normal (lower) or the actual measured value AM is less than 50% of the activity target value AT, it is determined in step S64 whether the blood glucose level is lower than or equal to. Then, if the blood glucose level is lower than the above level, the process proceeds to step S65, and if the blood glucose level is higher than the lower level (or higher), the process proceeds to step S66.

  When the blood glucose level is lower than the above, as described above, when 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 sets the METs target value MT at a predetermined stage (for example, minimum level during activity: METs) Perform processing to lower to 2). As a result, suppression of activity can be promoted, and the possibility of the user 100 becoming hypoglycemic can be reduced.

  On the other hand, if the blood glucose level is higher than the lower level (more than normal), the actual measured value AM for one hour before the blood sugar level measurement is equal to or less than a predetermined ratio of the target activity value AT (eg, 50% of the target activity value AT) It is not achieved in). Therefore, in step S66, the setting control unit 46 inquires of the user 100 about updating of the activity target value AT and the METs target value MT via the notification unit 36. Thus, the user 100 recognizes that his activity amount is low.

  Then, the target setting unit 48 lowers the activity target value AT to a predetermined rate (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). Thus, the user 100 is recommended to perform appropriate activities based on the changed activity target value AT and the METs target value MT. When the user 100 does not permit 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 activity target value AT and METs target value MT are set (maintained or changed) in steps S63, S65, S67, control unit 40 controls activity target value AT and METs target based on the blood glucose level through notification unit 36. It notifies that the value MT has been set (step S68). The activity monitoring unit 44 can promote the user 100 with appropriate activities by monitoring the activity actual value AM detected by the activity sensor 32 using the activity target value AT and the METs target value MT. It becomes.

  Referring back to FIG. 8B, the activity meter 10 performs the past trend processing in addition to the latest processing (overall management processing) in the blood sugar level cooperation processing. The past trend processing is to notify the user 100 of the possibility of hypoglycemia based on the amount of activity of the user 100 having hypoglycemia in the past. Hereinafter, this past tendency processing will be described with reference to FIG.

  In the past trend process, the activity amount monitoring unit 44 of the activity meter 10 continuously receives the detection signal of the activity amount sensor 32, and the activity measurement value AM of the user 100 is determined in a predetermined time unit (1 in this embodiment) It measures by time unit) (step S70). Then, the activity amount monitoring unit 44 stores the calculated actual measurement value AM in the actual measurement database 62 of the storage unit 41.

  When the trend monitoring unit 54 receives an instruction to update the activity amount from the activity amount monitoring unit 44 in units of time, it reads out the hypoglycemic database 64 and the recovery period database 66 of the storage unit 41 (step S71).

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

  Then, the trend monitoring unit 54 determines whether the current actual measurement value AM1 and the activity amount trend information Af are similar (step S73). For example, when the correlation coefficient R (see FIG. 7) is calculated in step S72, the similarity is determined if the correlation coefficient R is equal to or more than the comparison value (0.8) held in advance, and the process proceeds to step S74. Go to On the other hand, the trend monitoring unit 54 determines non-similarity in the case of less than the comparison value, skips the subsequent steps, and ends the present past trend processing.

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

  Furthermore, the target setting unit 48 and the METs setting unit 50 change the activity target value AT and the METs target value MT upon receiving the high similar determination result from the trend monitoring unit 54 (step S75). At this time, the trend monitoring unit 54 analyzes the past activity actual measurement value AM (activity amount trend information Af of the recovery period database 66) in the recovery period in which the blood sugar level recovers 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 equal to or less than a predetermined ratio (for example, 50%). The METs setting unit 50 changes the setting of the METs target value MT to the lowest level (METs = 2). In addition, when the setting control unit 46 changes the setting, the setting control unit 46 notifies that the activity target value AT and the METs target value MT based on the blood glucose level are set via the notification unit 36 (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 the blood glucose level for the user 100. The target value according to can be presented well. 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 can be conscious of appropriate activity and can suppress hypoglycemia as a result. . Therefore, the activity meter 10 can provide higher convenience.

  In this case, the activity meter 10 lowers the activity target value AT or the METs target value MT set by the user 100 when the blood glucose level is lower than or equal to normal (low), thereby reducing the user 100 whose blood glucose level is low. It can be made to recognize to suppress activity. Further, since the activity target value AT includes the target value of the number of walks of the user 100 and the target value of the fast walking time, the activity meter 10 can walk the number of walks or the fast walk based on the blood glucose level during the walking exercise of the user 100. The time can be presented well. Furthermore, the activity meter 10 can appropriately present walking strength (METs) such as the speed of walking based on the blood glucose level when the user 100 walks.

  Then, the activity meter 10 makes the user 100 recognize the amount of activity of the user 100 by inquiring a change in the activity target value AT when the actual measurement value AM does not reach the predetermined ratio 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. Furthermore, the activity meter 10 suppresses the user 100 from becoming hypoglycemic again during activity by determining the similarity between current activity amounts using the amount of activity that has become hypoglycemic in the past. Can. Moreover, the activity meter 10 can urge the user 100 to easily and quickly improve the activity by notifying the user of the warning that there is a possibility of hypoglycemia.

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

  Moreover, the structure which concerns on this invention is not limited to the walk measuring apparatus which measures the walk of the user 100, It is applicable to the active mass measuring apparatus 10 which measures various activities. For example, as other activity measuring devices, devices for measuring cardiopulmonary function and devices for measuring the amount of exercise of various exercises (a measuring device for abdominal muscles, push-ups, etc.) can be mentioned.
