[0001] This application is a divisional application of the parent application whose applicant is "Bailida Co., Ltd.", whose invention name is "Biological Information Measurement Device", whose application date is "March 03, 2020", and whose application number is "202080018364.6". Technical Field

[0002] The present invention relates to a biological information measuring device. Background Art

[0003] Biometric information measuring devices called body composition meters that measure biometric information other than body weight by improving a weight scale are becoming popular. For example, Patent Document 1 below describes a biometric information measuring device that displays measurement results in an order corresponding to the purpose of use of the biometric information measuring device.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2007-296093

[0005] In the biological information measuring device described in Patent Document 1, the measurement results are displayed only in the order corresponding to the purpose of use of the biological information measuring device, and the user of the biological information measuring device can only judge whether the change of his / her body (more specifically, the body composition as a body index) is preferable or undesirable for the purpose of use. In particular, if the user does not have professional knowledge, it is impossible to grasp where to pay attention to the measurement results of the body composition, and therefore the user only knows the measurement results randomly, and it is difficult to judge whether the change of his / her body is preferable for the purpose of use. Summary of the invention

[0006] Therefore, one of the objects of the present invention is to provide a biological information measuring device that can determine whether a change in the body composition of a user obtained by the biological information measuring device is preferable for the purpose of use of the body composition meter.

[0007] In order to solve the above-mentioned problem, the biological information measuring device of the present invention has a control unit, which determines the degree of matching with the purpose of use set in the measured data related to multiple body components based on the combination relationship of the change direction of the data related to multiple body components and based on the purpose of use matching relationship, wherein the above-mentioned data related to multiple body components establish a corresponding relationship according to the display order for the purpose of use, and the above-mentioned purpose of use matching relationship is associated with the degree of matching with the purpose of use.

[0008] According to at least one embodiment of the present invention, it is possible to determine how much a change in body composition data matches the purpose of use of the body composition meter. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The description will be given in the following order.

[0026] <One embodiment>

[0027] <Modification>

[0028] The embodiments and the like described below are preferred specific examples of the present invention, and the contents of the present invention are not limited to these embodiments and the like.

[0029] <One embodiment>

[0030] Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the embodiment described below, an example of applying the present invention to a biological information measuring device (hereinafter, appropriately referred to as a body composition meter) for measuring data related to body composition (hereinafter, appropriately referred to as body composition data) is described. As types of body composition, weight, fat rate, visceral fat level, body water content, muscle mass, basal metabolic rate, bone mass, fat-free mass, body cell mass, visceral fat area, BMI, obesity, intracellular fluid volume, extracellular fluid volume, etc. can be cited. In this embodiment, "weight", "body fat rate or body fat mass", "body age (an index indicating a body composition close to a few years old obtained based on basal metabolism, body fat and weight)", "basal metabolic rate", "visceral fat level", "muscle mass", "estimated bone mass", and "BMI" are used as types of body composition for description. These body composition data are obtained by the body composition meter through known measurements and calculations.

[0031] [About Body Composition Meter]

[0032] (Appearance of body composition meter)

[0033] Figure 1 FIG. 2 is a diagram showing the appearance of a body composition meter according to an embodiment of the present invention. Figure 1 As shown, the body composition monitor 1 has electrodes, a display unit, and an operation unit formed on an upper surface 11 of a mounting table 10 on which a user stands.

[0034] The upper surface 11 of the mounting platform 10 is formed to be approximately flat so that the user can step on (stand on). The upper surface 11 of the mounting platform 10 is a mounting area that the sole of the foot, which is a part of the user's body, contacts when measuring body composition data. The current supply electrode 15R, the current supply electrode 15L, the voltage measurement electrode 16R, and the voltage measurement electrode 16L formed of metal plates are formed separately from each other on the upper surface 11. In addition, each electrode may not be a metal plate as long as it has conductivity. Each electrode is not limited to a specific material, but as described above, by forming each electrode from a metal plate, the user can easily identify the position to place the foot.

[0035] The current supply electrode 15R and the current supply electrode 15L are electrodes for supplying current from the user's body part that makes contact (for example, the sole of the foot on the toe side) to the user's body. On the other hand, the voltage measuring electrode 16R and the voltage measuring electrode 16L are electrodes for detecting the voltage generated between the user's body parts that make contact (for example, between the sole of the right heel side and the sole of the left heel side). The user's biological impedance can be calculated based on the value of the supplied current and the detected voltage. In one embodiment, the sole of the toe side of the user's right foot contacts the current supply electrode 15R, and the sole of the heel side of the user's right foot contacts the voltage measuring electrode 16R. In addition, the sole of the toe side of the user's left foot contacts the current supply electrode 15L, and the sole of the heel side of the user's left foot contacts the voltage measuring electrode 16L.

[0036] A display unit 17 is provided on the upper surface of the mounting table 10. As the display unit 17, an LCD (Liquid Crystal Display), an organic EL (Electro Luminescence) display, etc. can be applied. Figure 1 As shown, the display unit 17 of the present embodiment has two displays. The display content described below is displayed on the display on the lower side of the display unit 17, for example. In addition, the display unit 17 can be one or more than three displays, or a display separate from the body composition meter 1. In the case where the display unit 17 is a display separate from the body composition meter 1, the measurement results of the body composition are sent from the body composition meter 1 to the display unit 17 through wired or wireless communication. And the measurement results of the body composition are received and displayed by the display unit 17. In addition, the display unit 17 can also be a display of a smartphone or a personal computer held by the user.

[0037] An operation unit 30 for accepting various inputs is provided on the upper surface of the mounting platform 10. For example, the operation unit 30 is provided on the lower side of the display unit 17 located near the center of the body composition meter 1. This can prevent the user from mistakenly operating the operation unit 30 with the sole of the foot when placing the foot on the mounting platform 10, thereby preventing the user from making an undesired operation input. In addition, by forming the operation unit 30 and the display unit 17 along the user's entry direction, the user can perform operation input on the operation unit 30 while checking the display of the display unit 17, and set the user's date of birth, etc.

[0038] The above is a description of the appearance example of the body composition meter 1. The user lifts one foot and places the foot on a pair of electrodes (e.g., the current supply electrode 15R and the voltage measurement electrode 16R) formed on the upper surface 11. Next, the user lifts the other foot and places the foot on another pair of electrodes (e.g., the current supply electrode 15L and the voltage measurement electrode 16L) formed on the upper surface 11. Then, the measurement of the user's body composition data starts.

[0039] [About the Operation Department]

[0040] The operation unit 30 of the present embodiment includes six touch switches (touch switch 30a, touch switch 30b, touch switch 30c, touch switch 30d, touch switch 30e, and touch switch 30f). Figure 2 The operation unit 30 is configured in the manner shown. In addition, the number and configuration position of the touch switches included in the operation unit 30 can be changed appropriately. In addition, the operation unit 30 is not limited to a touch switch, and may also be a mechanical switch (for example, a push button switch pressed by a user).

[0041] Here, an example of the functions assigned to the touch switches constituting the operation unit 30 is described. The touch switch 30a and the touch switch 30b are respectively an up key and a down key for increasing or decreasing a numerical value. The touch switch 30c is a menu key for displaying a menu. The touch switch 30d is a determination key used to confirm the selected switch. After the touch switch 30c is touched, by touching the touch switch 30a or the touch switch 30b, the menu items are switched such as (1) call measurement, (2) guest measurement, (3) last value, (4) speed change of result display, (5) setting of purpose of use, (6) display selection of measurement results, (7) data registration, (8) data deletion, (9) time change, and (10) region change. Furthermore, by touching the touch switch 30d, the user can set an item from the menu items. At this time, when the number of people registered in the data is 0, the above-mentioned menu items (1), menu item (3), menu item (4), menu item (5), menu item (6), and menu item (8) are not displayed. In addition, if the registered data is under 17 years old, the menu item (5) is not displayed.

[0042] The touch switch 30e is a weight key used when only weight measurement is desired. After the touch switch 30e is touched, if the body composition meter 1 is mounted, only weight measurement is performed. The touch switch 30f is an OFF key used when power is turned off or when setting or measurement is interrupted. For example, when the user wants to interrupt the selection at the stage of selecting the above-mentioned menu item, the touch switch 30f can be pressed.

[0043] "Example of the internal structure of a body composition meter (electrical structure)"

[0044] Next, an internal configuration example of the body composition monitor 1 according to one embodiment will be described. Figure 3 1 is a block diagram showing an example of the internal structure of a body composition monitor 1 according to an embodiment. The body composition monitor 1 includes, in addition to the display unit 17 and the operation unit 30, a calculation / control unit 50 (hereinafter, appropriately referred to as the control unit 50), a bioimpedance measurement unit 60, a weight measurement unit 70, and a storage unit 80. Since the display unit 17 and the operation unit 30 have been described in detail, their description is omitted here.

[0045] The control unit 50 uniformly controls each unit of the body composition meter 1 based on a program. The control unit 50 determines the degree of matching with the purpose of use set in the measured data related to the multiple body components based on the combination relationship of the change direction of the data related to the multiple body components and the purpose of use matching relationship, wherein the data related to the multiple body components are established in a corresponding relationship according to the display order for the purpose of use, and the purpose of use matching relationship is associated with the degree of matching with the purpose of use. An operation signal corresponding to the operation input to the operation unit 30 is supplied to the control unit 50. The control unit 50 performs control corresponding to the operation signal. In addition, the control unit 50 performs known control. In addition, the details of the processing performed by the control unit 50 will be described later.

[0046] The bioimpedance measurement unit 60 includes a current supply circuit 61 and a voltage detection circuit 62, as well as the current supply electrodes (15R, 15L) and the voltage measurement electrodes (16R, 16L) described above. When the user steps on the mounting platform 10, the current supply circuit 61 applies a high-frequency weak constant current to the sole of the user's foot via the current supply electrodes 15R and the current supply electrodes 15L formed on the upper surface 11 of the mounting platform. The voltage detection circuit 62 detects a potential difference via the voltage measurement electrodes 16R and the voltage measurement electrodes 16L, and outputs the difference to the control unit 50.

[0047] The body weight measurement unit 70 has, for example, a weight sensor 71 and a weight detection circuit 72. The weight sensor 71 can be, for example, a weighing sensor composed of a strain body and a strain gauge. One end of the strain body is supported inside the mounting platform 10, and the other end of the strain body is supported on a foot (not shown) on the back side of the mounting platform 10. If the strain body is bent due to the load when the user places it on the upper surface 11 of the mounting platform 10, the strain gauge expands and contracts, and the resistance value (output value) changes according to the expansion and contraction of the strain gauge. The change in resistance value can be used as a change in the load signal output to measure the body weight. The signal output from the weight sensor 71 is converted into weight data by the weight detection circuit 72 and output to the control unit 50.

[0048] The storage unit 80 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and a rewritable memory. The ROM is a nonvolatile memory, and programs for causing the control unit 50 to execute various processes are stored in the ROM. In addition, the ROM stores calculation formulas for calculating each of body fat percentage, body age, basal metabolic rate, visceral fat level, muscle mass, estimated bone mass, BMI, and body weight. In addition, as these programs, programs stored in a storage device different from the ROM, such as an optical storage medium such as a hard disk or a CD, can also be used.

[0049] The RAM functions as a work area of ​​the control unit 50. In the rewritable memory, personal data such as height, age, sex, and body composition data measured in the past are stored in association with identification information for identifying the individual.

[0050] In addition, display order data and advice information associated with the purpose of use are stored in the storage unit 80. The display order data is data that defines the display order of the measured body composition data.

[0051] Figure 4 Display order data and suggestion information associated with the purpose of use are shown. Figure 4As shown, "losing weight" as one of the purposes of using the body composition meter 1 is associated with display order data for displaying measurement results in the order of weight, body fat percentage, body age, basal metabolic rate, visceral fat level, muscle mass, estimated bone mass, and BMI. "Exercise and tightening" as one of the purposes of using the body composition meter 1 is associated with display order data for displaying measurement results in the order of weight, muscle mass, body fat percentage, basal metabolic rate, body age, visceral fat level, estimated bone mass, and BMI. "Maintaining health" as one of the purposes of using the body composition meter 1 is associated with display order data for displaying measurement results in the order of weight, body fat percentage, visceral fat level, body age, muscle mass, estimated bone mass, BMI, and basal metabolic rate. "Wanting to gain weight" as one of the purposes of using the body composition meter 1 is associated with display order data for displaying measurement results in the order of weight, BMI, body fat percentage, muscle mass, estimated bone mass, basal metabolic rate, visceral fat level, and body age. The purpose of use of the body composition monitor 1 is "not set" and is associated with display order data for displaying the measurement results in the order of weight, body fat percentage, visceral fat level, muscle mass, body age, basal metabolic rate, estimated bone mass, and BMI. The display order data is defined as the order of body components that are considered important for each purpose of use.

[0052] In addition to the display order data, each usage purpose is also associated with the recommended information of the content corresponding to the usage purpose. Figure 4 As shown, for example, "weight loss" as one of the usage purposes is associated with the advice information AD1. In addition, "exercise and tightening" as one of the usage purposes is associated with the advice information AD2. Although not shown in the figure, each of the usage purposes "maintain health", "want to gain weight", and "not set" is also associated with the prescribed advice information.

[0053] In addition, the purpose of use matching relationship is stored in the storage unit 80. The purpose of use matching relationship is a relationship in which the degree of matching with the purpose of use is associated with a combination of the related change directions of a plurality of body component-related data corresponding to each other in the display order for the purpose of use. In other words, in the order of the body component-related data from high to low importance to the purpose of use, each classification of the change direction of the body component-related data is associated with a classification of the change direction of the next ranked body component-related data.

[0054] Figure 5 An example of the usage purpose matching relationship corresponding to the usage purpose "weight loss" is shown. Figure 5 The usage purpose matching degree relationship shown is a usage purpose matching degree relationship used in the case of male weight loss, that is, a usage purpose matching degree relationship for men.

[0055] When the purpose of use is "weight loss", the degree of matching with "weight loss" is associated according to the combined relationship of the relevant change directions of "body fat percentage (%)", "body age", and "basal metabolic rate" that have a corresponding relationship according to the display order for "weight loss". Here, "body fat percentage (%)", "body age", and "basal metabolic rate" are body composition data from high to low importance for the purpose of use "weight loss". That is, the purpose matching relationship corresponding to the purpose of use "weight loss" in this example is that in the order of data related to body composition (in this example, "body fat percentage (%)") from high to low importance to the purpose of use "weight loss", each classification of the change direction of "body fat percentage (%)" is associated with the classification of the change direction of data related to the next ranked body composition (in this example, "body age"), and each classification of the change direction of "body age" is associated with the classification of the change direction of data related to the next ranked body composition (in this example, "basal metabolic rate").

[0056] like Figure 5 As shown, according to the combination relationship of the change direction, there is an associated degree of matching with "weight loss". The matching degree in this example is the purpose matching evaluation ranking associated with the combination relationship of the change direction and the purpose matching evaluation data obtained by scoring the purpose matching evaluation ranking. The purpose matching evaluation data is displayed as a comprehensive evaluation of body composition changes.

[0057] The usage purpose matching relationship also includes suggestion information corresponding to the degree of matching with the usage purpose. Figure 6 A shows an example of recommended information when the purpose of use is "weight loss", "body fat percentage (%)", "body age", and "basal metabolic rate" show good changes for "weight loss", and the purpose matching evaluation ranking is high (for example, the purpose matching evaluation ranking is first or second). In addition, Figure 6 B shows an example of recommended information when the purpose of use is "weight loss" and the purpose matching evaluation ranking is a medium ranking, specifically, the "body fat percentage (%)" is reduced but the "basal metabolic rate" is also reduced (the purpose matching evaluation rankings are third, sixth, and ninth).

[0058] [Example of body composition meter operation]

[0059] (About setting mode)

[0060] Next, an operation example of the body composition monitor 1 will be described. Figure 7The flowchart shown in FIG. 1 illustrates an example of the operation of the body composition monitor 1 in the setting mode for performing various settings on the body composition monitor 1. The processing described below is executed under the control of the control unit 50 according to the input made to the operation unit 30. The setting content is stored in the storage unit 80. In the following description, there is a case where information related to the user (such as the personal number, date of birth, and gender information described later) that can be set in the setting mode is referred to as attributes.

[0061] In step ST1, by touching the touch switch 30c (menu key), menu items are displayed on the display unit 17. Then, the process proceeds to step ST2.

[0062] In step ST2, the menu item is switched by the user's operation. The menu item can be switched by touching the touch switch 30a (up key) or the touch switch 30b (down key), and the menu item is set by touching the touch switch 30d (determine key).

[0063] In step ST2, if menu item (7) (data login) is set, the process proceeds to step ST3. In step ST3, the setting screen of the personal number is displayed on the display unit 17, and the setting of the personal number is completed. The so-called personal number is an identification number between users (for example, family members, etc.) who use the same body composition meter 1, for example, an integer from 1 to 5. In this case, 5 users can be registered. After selecting the identification number by touching the touch switch 30a (up key) or the touch switch 30b (down key), the personal number is set by touching the touch switch 30d (confirm key). Then, the process proceeds to step ST4.

[0064] In step ST4, the user's birth year is set. The birth year is set, for example, by the Gregorian calendar. After selecting a year by touching the touch switch 30a (up key) or the touch switch 30b (down key), the user's birth year is set by touching the touch switch 30d (confirm key). Then, the process proceeds to step ST5.

[0065] In step ST5, the user's birth month is set. After selecting a month by touching the touch switch 30a (up key) or the touch switch 30b (down key), the user sets the birth month by touching the touch switch 30d (determine key). Then, the process proceeds to step ST6.

[0066] In step ST6, the user's date of birth is set. After selecting a date by touching the touch switch 30a (up key) or the touch switch 30b (down key), the user's date of birth is set by touching the touch switch 30d (determine key). Then, the process proceeds to step ST7.

[0067] In step ST7, the user's gender is set. After selecting the gender by touching the touch switch 30a (up key) or the touch switch 30b (down key), the user's gender is set by touching the touch switch 30d (determine key). Then, the process proceeds to step ST8.

[0068] In step ST8, the height of the user is set. After selecting the height (numerical value) by touching the touch switch 30a (up key) or the touch switch 30b (down key), the height of the user is set by touching the touch switch 30d (determine key). Then, the process proceeds to step ST9.

[0069] In step ST9, the purpose of use of the body composition meter 1 is set. The so-called purpose of use refers to how the user who uses the body composition meter 1 wants to manage his or her body. In this embodiment, four purposes of use can be set: "weight loss", "exercise and tighten", "maintain health", and "want to gain weight". In addition, the purpose of use can also be set to "not set". After selecting the purpose of use by touching the touch switch 30a (up key) or the touch switch 30b (down key), the purpose of use of the body composition meter 1 is set by touching the touch switch 30d (confirm key). Then, the process enters step ST12, and the process of setting various information ends.

[0070] The processing of steps ST3 to ST9 described above is performed as initial registration when the body composition monitor 1 is used for the first time after purchase, for example.

[0071] In step ST2, if menu item (5) (setting of purpose of use) is selected, the process proceeds to step ST10. In step ST10, the personal number is set. In the personal number setting in step ST10, the personal number whose attributes have been registered is selected. When the personal number is selected, the process proceeds to step ST11.

[0072] In step ST11, the same operation as in step ST9 is performed to set the purpose of use of the body composition monitor 1. Then, the process proceeds to step ST12, and the process of newly setting or changing the purpose of use is terminated.

[0073] By performing the processing of step ST10 and step ST11, even if the purpose of use of the body composition monitor 1 is not set at the initial login, the purpose of use can be set later. In addition, if the purpose of use of the body composition monitor 1 is set at the initial login, the user can also change the purpose of use of the body composition monitor 1 according to changes in the rhythm of life, etc.

[0074] (About measurement mode)

[0075] Next, refer to Figure 8The flowchart shown in the figure explains an example of the operation of the body composition monitor 1 in the measurement mode.

[0076] In step ST21, in response to the user's action of stepping onto the upper surface 11 of the mounting table 10, the process related to the measurement mode is started in the body composition monitor 1. In addition, in this example, the user who has registered the attributes steps onto the body composition monitor 1. The personal number, which is one of the attributes, may be input when the user steps onto the body composition monitor 1, or may be automatically recognized by the body composition monitor 1. Then, the process proceeds to step ST22.

[0077] In step ST22, the body weight and the bioimpedance are measured by the body composition meter 1, and various body composition data are measured by calculation using these information. The body composition data measured at this stage is appropriately referred to as the user's current measurement result data. In addition, the body composition data of the user measured before and stored in the storage unit 80 is appropriately referred to as the past measurement result data. Then, the process proceeds to step ST23.

[0078] In step ST23, the control unit 50 determines the purpose of use corresponding to the personal number, and determines the display order data corresponding to the determined purpose of use. In the following description, the process of determining the display order data is appropriately referred to as process A. Then, the process proceeds to step ST24.

[0079] In step ST24, the control unit 50 refers to the information stored in the storage unit 80 to determine whether there is past measurement result data corresponding to the personal number. If there is no past measurement result data corresponding to the personal number, the process proceeds to step ST25.

[0080] In step ST25, the measurement result data of the body composition measured in step ST22 is displayed on the display unit 17 in the display order based on the display order data determined in the above-mentioned process A. Then, the process proceeds to step ST26.

[0081] In step ST26, after the body composition measurement result is displayed, advice information related to the purpose of use is displayed. Then, the process proceeds to step ST32, and a series of processes are terminated.

[0082] In the determination process of step ST24, if the past measurement result data is stored in the storage unit 80, the process proceeds to step ST27. In step ST27, the control unit 50 determines the existence of the measurement result data related to the plurality of body components measured in the past, specifically, the number of past measurement result data stored in the storage unit 80. If the number of past measurement result data is 2 to 4, the process proceeds to step ST28.

[0083] In step ST28, the control unit 50 determines an approximate line using the past measurement result data measured within a specified period as a sample. For example, consider an example in which three pieces of past measurement result data are stored in the storage unit 80 for each body component. The control unit 50 determines an approximate line using the three pieces of past measurement result data for each body component. The approximate line is a straight line obtained by plotting the three pieces of past measurement result data with the horizontal axis as the time axis and the vertical axis as the measurement result data of the body component, and applying the least squares method, etc. to it. In addition, the control unit 50 determines the difference between the current measurement result data and the measurement result data on the current corresponding approximate line ("current measurement result data" - "measurement result data on the current corresponding approximate line"). Then, the processing enters step ST29.

[0084] In step ST29, the control unit 50 determines the changing trend of each body component based on the difference calculated in step ST28. For example, if the difference is within a certain range, the control unit 50 determines it as "no change", and when the difference is + and above a certain range, the control unit 50 determines it as "+ change", and when the difference is - and above a certain range, the control unit 50 determines it as "- change". The control unit 50 determines the purpose matching evaluation ranking corresponding to the combined relationship of the changing trend of each body component and the purpose matching evaluation data obtained by scoring the purpose matching evaluation ranking based on the use of the purpose matching relationship. For example, when the changing trend of "body fat percentage (%)" is - change, the changing trend of "body age" is - change, and the changing trend of "basal metabolic rate" is + change, the purpose matching evaluation ranking is "first", and the purpose matching evaluation data becomes "100 points" (refer to Figure 5 ).

[0085] In addition, in the processing involved in step ST29, each body component is evaluated for its changing trend (e.g., scored). For example, regarding the "body fat percentage", if the changing trend based on the difference obtained in step ST28 is "-change", a high score is assigned, if the changing trend based on the difference obtained in step ST28 is "no change", a medium score is assigned, and if the changing trend based on the difference obtained in step ST28 is "+change", a low score is assigned.

[0086] In addition, the control unit 50 determines the advice information associated with the purpose matching evaluation ranking and the purpose matching evaluation data. In the following description, the process involved in step ST29 is appropriately referred to as "processing B". When the process of step ST29 is completed, the process proceeds to step ST30.

[0087] In step ST30 , the current measurement result data of each body component is displayed based on the display order data determined in the above-mentioned process A. Then, the process proceeds to step ST31 .

[0088] In step ST31 , the control unit 50 displays the purpose matching degree evaluation data and the advice information determined in process B. Then, the process proceeds to step ST32 , and a series of processes are terminated.

[0089] In the determination process according to step ST27 , when the number of past measurement result data is 5 or more, the process proceeds to step ST33 .

[0090] In step ST33, the control unit 50 uses the past measurement result data measured within a specified period as a sample to determine the approximate line. For example, consider an example in which 10 pieces of past measurement result data are stored in the storage unit 80 for each body component. The control unit 50 determines the approximate line using the 10 pieces of past measurement result data for each body component. The approximate line is a straight line obtained by plotting the 10 pieces of past measurement result data with the horizontal axis as the time axis and the vertical axis as the measurement result data of the body component, and applying the least squares method, etc. to it. In addition, the control unit 50 determines the difference between the current measurement result data and the measurement result data on the current corresponding approximate line ("current measurement result data" - "measurement result data on the current corresponding approximate line"). Then, the processing enters step ST29.

[0091] Since the specific contents of the processing involved in step ST29 to step ST31 have been described, only a brief description is given. In step ST29, the control unit 50 determines the change trend of each body component based on the difference obtained in step ST33. In addition, the control unit 50 determines the purpose matching evaluation ranking corresponding to the combination relationship of the change trend of each body component and the purpose matching evaluation data obtained by scoring the purpose matching evaluation ranking based on the use of the purpose matching relationship. In addition, in the processing involved in step ST29, each body component is evaluated for the change trend (for example, scored). In addition, the control unit 50 determines the recommendation information associated with the purpose matching evaluation ranking and the purpose matching evaluation data. Then, the processing enters step ST30.

[0092] In step ST30 , the current measurement result data of each body component is displayed based on the display order data determined in the above-mentioned process A. The process proceeds to step ST31 .

[0093] In step ST31 , the control unit 50 displays the purpose matching degree evaluation data and the advice information determined in the process B. Then, the process proceeds to step ST32 , and a series of processes are terminated.

[0094] In the determination process involved in step ST27, if there are not a plurality of past measurement result data, in other words, if there is only one past measurement result data, the process proceeds to step ST34. In addition, in step ST34, the difference between the current measurement result data and the one past measurement result data is determined. Then, the process proceeds to step ST29.

[0095] In step ST29, the control unit 50 determines the change trend of each body component based on the difference determined in step ST34. For example, if the difference determined in step ST34 is within a certain range, the control unit 50 determines that it is "no change", and when the difference is + and is above a certain range, the control unit 50 determines that it is "+ change", and when the difference is - and is above a certain range, it is determined that it is "- change". In addition, the control unit 50 determines the purpose matching evaluation ranking corresponding to the combination relationship of the change trend of each body component and the purpose matching evaluation data obtained by scoring the purpose matching evaluation ranking based on the use of the purpose matching relationship. In addition, in the processing involved in step ST29, each body component is evaluated for the change trend (for example, scored). In addition, the control unit 50 determines the recommendation information associated with the purpose matching evaluation ranking and the purpose matching evaluation data. Then, the processing enters step ST30.

[0096] In step ST30 , the current measurement result data of each body component is displayed based on the display order data determined in the above-mentioned process A. Then, the process proceeds to step ST31 .

[0097] In step ST31 , the control unit 50 displays the purpose matching degree evaluation data and the advice information determined in the process B. Then, the process proceeds to step ST32 , and a series of processes are terminated.

[0098] Fig. 9 The following is a specific display example of the processing involved in the above step ST25 when "weight loss" is set as the purpose of use. Since "weight loss" is set as the purpose of use, the display sequence data associated with "weight loss" is displayed in the following order. Fig. 9 The measurement result data of the body composition are displayed in the order shown in <1> to <8> (weight→body fat percentage→body age→basal metabolic rate→visceral fat→muscle mass→estimated bone mass→BMI).

[0099] Fig.10 2 shows a specific display example of the processing involved in step ST26 when "weight loss" is set as the purpose of use. Fig.10As shown in FIG. 1 , the suggestion information AD1 associated with the purpose of use "weight loss" is displayed on the display unit 17. In addition, in step ST26, since there is no past measurement result data, the purpose matching evaluation data cannot be determined. Therefore, in step ST26, as shown in FIG. Fig.10 As shown, the display this time cannot determine the meaning of the specific content of the "comprehensive evaluation of body composition changes". In other words, the display shows comment C1 that will determine the meaning of the "comprehensive evaluation of body composition changes" from next time.

[0100] Fig.11 FIG. 2 shows a specific display example of the processing involved in the above step ST30 when “weight loss” is set as the purpose of use. Since “weight loss” is set as the purpose of use, the display sequence data associated with “weight loss” is displayed in the following order: Fig.11 The current measurement result data is displayed in the order shown in <1> to <8> (weight → body fat percentage → body age → basal metabolic rate → visceral fat → muscle mass → estimated bone mass → BMI). In addition, in step ST30, the change trend of each body component determined in step ST29 is associated and displayed. That is, when the change trend of the body composition is "no change", "→" is displayed next to the display indicating the type of body composition; when the change trend of the body composition is "+change", "↑" is displayed next to the display indicating the type of body composition; when the change trend of the body composition is "-change", "↓" is displayed next to the display indicating the type of body composition.

[0101] Fig.12 2 shows a specific display example of the processing involved in the above-mentioned step ST31 when "weight loss" is set as the usage purpose. Fig.12 As shown, the control unit 50 displays the suggestion information AD5 in the upper half of the display unit 17. In addition, the control unit 50 displays an item such as "Comprehensive evaluation of changes in body composition" below the suggestion information AD5, and displays "90 points" as the purpose matching evaluation data on the right side of the item. In addition, the control unit 50 displays the body components that are more important for the purpose of use "weight loss" from top to bottom in descending order of importance below the item "Comprehensive evaluation of changes in body composition", namely "body fat percentage", "body age" and "basal metabolism". Furthermore, next to the display indicating the type of body composition, an arrow corresponding to the change trend determined in step ST29, a length bar corresponding to the score of each body component assigned to the change trend, and a specific score are displayed. Fig.12In the example shown, for example, an arrow "↓" indicating a change trend "-change" is displayed on the right side of "body fat percentage", a bar such as "******************" is displayed on the right side of the arrow "↓", and a score "99 points" assigned to the change trend of "body fat percentage" is further displayed on the right side of the bar. The bar is displayed so that the higher the score, the longer it extends to the right side.

[0102] According to the embodiment described above, it is possible to judge whether the changes in one's body are in a good direction or a bad direction according to the purpose of using the body composition meter. Since the judgment result is displayed to the user, even if the user does not have professional knowledge, it can be a clue to understand whether the body changes based on daily life tendencies and directions of efforts are in line with the purpose of use, and grasp the essential meaning of the measurement results. Therefore, it is not only easy to get a real feeling of the changes, but also easy to continue to work towards the purpose and improve life for a long time, so that enthusiasm can be effectively maintained, and the body composition meter can be effectively used for guidance in gyms, facilities for beauty purposes, etc.

[0103] <Modification>

[0104] Although one embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the technical concept of the present invention. Modifications will be described below.

[0105] Fig.13 This is a diagram showing another example of the usage purpose matching relationship. Fig.13 The example shown is an example of the purpose matching relationship when the purpose of use of the body composition meter 1 is "exercise and tightening". In the purpose matching relationship when the purpose of use is "exercise and tightening", "muscle mass", "body fat percentage" and "basal metabolic rate" are used as multiple body components in descending order of importance.

[0106] Fig.14 An example of suggestion information associated with the usage purpose matching relationship of "exercise and tightening" is shown. Specifically, the user's body composition has not changed much, and the purpose matching evaluation data is a medium score (for example, Fig.13 The example shown is an example of establishing associated suggestion information using the purpose matching relationship (the purpose matching evaluation ranking corresponds to the fourteenth score).

[0107] Fig.15 This is a diagram showing another example of the usage purpose matching relationship. Fig.15The example shown is an example of the purpose of use matching relationship when the purpose of use of the body composition meter 1 is "maintaining health". In the purpose of use matching relationship when the purpose of use is "maintaining health", "body fat percentage", "internal fat level" and "body age" are used as multiple body components in descending order of importance.

[0108] Fig.16 The example shown is an example of the usage purpose matching relationship when the usage purpose of the body composition monitor 1 is "weight loss". Figure 5 The purpose of use shown is for men. Fig.16 The purpose of use matching relationship shown is different for women. If the user is a woman, during the period of body swelling, even if the body fat amount is reduced, the weight will increase, so the body fat percentage of the total body weight will not decrease. Considering this situation, in the case of women, using "body fat amount" instead of "body fat percentage" can make an appropriate evaluation. Therefore, when the personal attribute set in the setting mode is "female", even if the purpose of use is the same, it is used. Fig.16 Thus, even if the purpose of use is the same, the purpose of use matching relationship used can be changed according to the attributes of the individual.

[0109] In the above-mentioned embodiment, an approximate line based on the measurement result data measured within a specified period in the past is judged, and the difference between the current measurement result data and the measurement result data on the current corresponding approximate line is judged. The above-mentioned specified period can also be set for the user. Generally, in order to evaluate whether the changes in the body are changes that match "weight loss", a long period of past measurement result data is required to some extent. However, during this period, the user may also take actions that violate the purpose of use. For example, there may be a period when the user overeats even if the purpose of use is "weight loss". It is preferred to exclude such a period, that is, the measurement result data during the period when the user is seriously committed to losing weight. Therefore, the user can also set the scope of use of the past measurement result data (for example, within the past week, the date range is specified).

[0110] In the above-described embodiment, when there is a large deviation in the past measurement result data, comments such as “The measurement results are not regular”, “It looks like an eventful life. Let’s review the rhythm of life” may be displayed.

[0111] In the above-mentioned embodiment, after the measurement result data of each body component are displayed, the purpose matching evaluation data and the suggestion information are displayed, but the purpose matching evaluation data and the suggestion information may be displayed first. It takes a certain amount of time to display the measurement result data of all body components, so the purpose matching evaluation data and the suggestion information may be displayed to the user first. In addition, the purpose matching evaluation data and the suggestion information may be displayed first, and the measurement result data of each body component may be displayed only when there is a prescribed operation. In addition, the user may be able to set which information to display first among the purpose matching evaluation data, the suggestion information and the measurement result data of the body component. In this way, the user can display the information that interests him first.

[0112] Even when past measurement result data is not stored in the storage unit 80, the current measurement result data can be compared with the average value of the measurement result data of the body composition related to a certain attribute. In addition, the change trend can be determined based on the difference between the current measurement result data and the average value, and the change trend can be scored and displayed.

[0113] The information displayed in step S31 may be changed according to the number of past measurement result data. For example, if there are more than five past measurement result data, it may be displayed in step ST31 that the reliability of the comprehensive evaluation of body composition changes is high. On the contrary, if there is only one past measurement result data, it may be displayed in step ST31 that the reliability of the comprehensive evaluation of body composition changes is low.

[0114] The degree of matching associated with the purpose of use matching relationship may also be an indicator other than the purpose matching evaluation ranking and the purpose matching evaluation data, as long as it is an indicator indicating the degree of matching. In addition, in the above-mentioned embodiment, when determining whether it matches (is suitable for) the purpose of use, three are set in descending order of importance of body composition, but it may also be two or more than four.

[0115] The body composition monitor 1 in the above-mentioned embodiment may be provided with a structure that allows the monitor to be held with the left and right hands, and electrodes for the left and right hands may be arranged on the portion held with the hands to perform impedance measurement with the hands and feet.

[0116] You can also add the following to the body composition meter 1: Figure 3 The structure shown in the figure is different from the structure shown in the figure. For example, a communication module for short-range wireless communication with mobile devices such as smartphones and a communication module for connecting to networks such as the Internet can be added to the body composition meter 1. All or part of the calculations performed in the body composition meter 1 can also be performed in a smartphone or a server device on the cloud. In addition, the purpose matching evaluation data and recommendation information can also be played by sound.
