Description

[Technical field]

[0001] The present invention relates to a biological information measuring device. [Background technology]

[0002] As weight scales have been improved, biological information measuring devices called body composition monitors that measure biological information other than weight have become widespread. For example, the following Patent Document 1 describes a biological information measuring device that displays measurement results in an order corresponding to the purpose of use of the biological information measuring device. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2007-296093 A Summary of the Invention [Problem to be solved by the invention]

[0004] The biological information measuring device described in Patent Document 1 only displays the measurement results in an order corresponding to the intended use of the biological information measuring device, and the user of the biological information measuring device has to judge for himself whether the changes in his / her body (more specifically, body composition, which is an index of the body) are favorable for the intended use or not. In particular, if the user does not have specialized knowledge, he / she cannot understand what to pay attention to in the measurement results of body composition, and so only learns the measurement results vaguely, making it difficult to judge whether the changes in his / her body are favorable for the intended use.

[0005] Therefore, one of the objectives of the present invention is to provide a vital information measuring device that is capable of determining whether changes in a user's body composition obtained by the vital information measuring device are desirable for the purpose of using the body composition monitor. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides This is a biological information measuring device having a control unit that determines the degree of match between a plurality of measured body composition data and a set purpose of use, based on a purpose of use match relationship in which the degree of match with the purpose of use is associated depending on a combination relationship regarding the direction of change of a plurality of body composition data that are associated in display order with the purpose of use. Effect of the Invention

[0007] According to at least the embodiment of the present invention, it is possible to determine how well a change in body composition data matches the intended use of the body composition monitor. [Brief description of the drawings]

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The description will be given in the following order. <One embodiment> <Modification> The embodiments and the like described below are preferred specific examples of the present invention, and the content of the present invention is not limited to these embodiments and the like.

[0010] <One embodiment> An embodiment of the present invention will be described in detail below with reference to the drawings. In the embodiment described below, an example in which the present invention is applied to a biological information measuring device (hereinafter, referred to as a body composition meter) that measures data related to body composition (hereinafter, referred to as body composition data) will be described. Types of body composition include body weight, fat percentage, visceral fat level, body water content, muscle mass, basal metabolic rate, bone mass, fat-free mass, body cell mass, visceral fat area, BMI, obesity level, intracellular fluid volume, extracellular fluid volume, etc. In this embodiment, types of body composition are described using "body weight", "body fat percentage or body fat mass", "body age (an index indicating the age of the body composition obtained based on basal metabolic rate, body fat, and body weight)", "basal metabolic rate", "visceral fat level", "muscle mass", "estimated bone mass", and "BMI". These body composition data are acquired by the body composition meter by performing known measurements and calculations.

[0011] [About body composition scales] (External appearance of the body composition scale) Fig. 1 is a diagram showing the external appearance of a body composition monitor according to an embodiment of the present invention. As shown in Fig. 1, the body composition monitor 1 has electrodes, a display unit, and an operation unit formed on an upper surface 11 of a platform 10 on which a user stands.

[0012] The top surface 11 of the platform 10 is made substantially flat so that the user can stand (stand) on it. The top surface 11 of the platform 10 is a placement area that is in contact with the soles of the feet, which are part of the user's body, when measuring body composition data, and current supply electrodes 15R, 15L, voltage measurement electrodes 16R, and voltage measurement electrodes 16L, which are made of metal plates, are formed on the top surface 11 at a distance from each other. Note that each electrode does not have to be made of a metal plate as long as it is conductive. Although each electrode is not limited to a specific one, by forming each electrode from a metal plate as described above, the user can easily recognize the position on which to place the foot.

[0013] The current supplying electrode 15R and the current supplying electrode 15L are electrodes for supplying a current into the user's body from a part of the body that the user touches (for example, the sole of the foot on the toe side). On the other hand, the voltage measuring electrode 16R and the voltage measuring electrode 16L are electrodes for detecting a voltage generated between parts of the body that the user touches (for example, between the sole of the right heel side and the sole of the left heel side). The bioimpedance of the user can be obtained 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 supplying electrode 15R, and the sole of the heel side of the user's right foot contacts the voltage measuring electrode 16R. Also, the sole of the toe side of the user's left foot contacts the current supplying electrode 15L, and the sole of the heel side of the user's left foot contacts the voltage measuring electrode 16L.

[0014] A display unit 17 is provided on the upper surface of the platform 10. As the display unit 17, an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescence) display, etc., can be used. As shown in FIG. 1, the display unit 17 according to this embodiment has two displays. The display contents described below are displayed, for example, on the display on the lower side of the display unit 17. The display unit 17 may have one or three or more displays, or may be a display separate from the body composition meter 1. When the display unit 17 is a display separate from the body composition meter 1, the body composition meter 1 transmits the measurement result of the body composition to the display unit 17 by wired or wireless communication. The measurement result of the body composition is then received and displayed by the display unit 17. The display unit 17 may be a display of a smartphone or a personal computer owned by the user.

[0015] An operation unit 30 that accepts various inputs is provided on the upper surface of the platform 10. For example, the operation unit 30 is provided below the display unit 17 located near the center of the body composition monitor 1. This prevents the user from accidentally operating the operation unit 30 with the sole of the foot and performing unintended operation input when placing the user's foot on the platform 10. In addition, by forming the operation unit 30 and the display unit 17 along the user's approach direction, the user can perform operation input to the operation unit 30 while checking the display of the display unit 17, and set the user's date of birth, etc.

[0016] The above describes an example of the external appearance of the body composition meter 1. The user lifts one foot and places it on a pair of electrodes (e.g., current supply electrode 15R and voltage measurement electrode 16R) formed on the upper surface 11. Next, the user lifts the other foot and places it on another pair of electrodes (e.g., current supply electrode 15L and voltage measurement electrode 16L) formed on the upper surface 11. Then, measurement of the user's body composition data begins.

[0017] [About the operation panel] The operation unit 30 according to this embodiment has six touch switches (touch switch 30a, touch switch 30b, touch switch 30c, touch switch 30d, touch switch 30e, and touch switch 30f), and these touch switches are arranged as shown in FIG. 2. The number and arrangement of the touch switches in the operation unit 30 can be changed as appropriate. The operation unit 30 is not limited to touch switches, and may be mechanical switches (for example, push switches pressed by the user).

[0018] Here, an example of a function assigned to each touch switch constituting the operation unit 30 will be described. The touch switch 30a and the touch switch 30b are an up key and a down key for increasing and decreasing a numerical value, respectively. The touch switch 30c is a menu key for displaying a menu. The touch switch 30d is a decision key used to confirm a selection. After touching the touch switch 30c, the menu items are switched such as (1) call measurement, (2) guest measurement, (3) previous value, (4) change of result display speed, (5) setting of purpose of use, (6) display selection of measurement results, (7) data registration, (8) data deletion, (9) date and time change, and (10) area change by touching the touch switch 30d. Then, the user can set one of the menu items by touching the touch switch 30d. In this case, if the number of registered data users is 0, the above-mentioned menu items (1), (3), (4), (5), (6) and (8) will not be displayed. Also, if the registered data user is 17 years old or younger, menu item (5) will not be displayed.

[0019] Touch switch 30e is a weight key used when only weight is to be measured. After touching touch switch 30e, stepping on body composition scale 1 measures only weight. Touch switch 30f is an OFF key used to turn off the power or to interrupt settings or measurement. For example, when selecting the above-mentioned menu items, if the user wishes to interrupt the selection, he or she can simply press touch switch 30f.

[0020] "Example of the internal configuration of a body composition analyzer (electrical configuration)" Next, an example of the internal configuration of the body composition meter 1 according to one embodiment will be described. Fig. 3 is a block diagram showing an example of the internal configuration of the body composition meter 1 according to one embodiment. In addition to the above-mentioned display unit 17 and operation unit 30, the body composition meter 1 includes a calculation and control unit 50 (hereinafter, appropriately abbreviated to control unit 50), a bioimpedance measuring unit 60, a body weight measuring unit 70, and a storage unit 80. Details of the display unit 17 and operation unit 30 have already been described, so description thereof will be omitted here.

[0021] The control unit 50 performs overall control of each unit of the body composition monitor 1 based on a program. The control unit 50 determines the degree of matching of the measured data relating to the body composition with the set purpose of use based on a purpose of use matching degree relationship in which the degree of matching with the purpose of use is associated with a combination relationship regarding the change direction of the data relating to the body composition that is associated with the purpose of use in the display order of the data. The control unit 50 is supplied with an operation signal corresponding to an operation input to the operation unit 30. The control unit 50 executes control corresponding to the operation signal. The control unit 50 also executes other known controls. Details of the processing performed by the control unit 50 will be described later.

[0022] The bioimpedance measuring unit 60 has a current supply circuit 61, a voltage detection circuit 62, and the above-mentioned current supply electrodes (15R, 15L) and voltage measurement electrodes (16R, 16L). When the user stands on the platform 10, the current supply circuit 61 applies a high-frequency, weak constant current to the soles of the user's feet via the current supply electrodes 15R and 15L formed on the upper surface 11 of the platform. The voltage detection circuit 62 detects a potential difference via the voltage measurement electrodes 16R and 16L, and outputs it to the control unit 50.

[0023] The weight measuring unit 70 has, for example, a weight sensor 71 and a weight detection circuit 72. For example, a load cell consisting of a strain body and a strain gauge can be applied to the weight sensor 71. One end of the strain body is supported inside the platform 10, and the other end of the strain body is supported by a leg (not shown) on the rear side of the platform 10. When the strain body is bent by the load when the user stands on the upper surface 11 of the 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. This change in resistance value can be used to measure the weight as a change in the load signal output. 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.

[0024] 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 non-volatile memory, and stores programs for causing the control unit 50 to execute various processes. The ROM also stores arithmetic expressions for calculating the body fat percentage, body age, basal metabolic rate, visceral fat level, muscle mass, estimated bone mass, BMI, and body weight. Note that these programs may be stored in a storage device other than the ROM, for example, a program stored in an optical storage medium such as a hard disk or a compact disk.

[0025] The RAM functions as a work area for the control unit 50. The rewritable memory stores personal data such as height, age, sex, and previously measured body composition data in association with identification information for identifying an individual.

[0026] Display order data and advice information associated with the intended use are also stored in the storage unit 80. The display order data is data that specifies the order in which measured body composition data is displayed.

[0027] FIG. 4 shows display order data and advice information associated with the intended use. As shown in FIG. 4, one of the intended uses of the body composition meter 1, "dieting," is associated with display order data for displaying the 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. One of the intended uses of the body composition meter 1, "I want to train and get toned," is associated with display order data for displaying the 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. One of the intended uses of the body composition meter 1, "maintaining health," is associated with display order data for displaying the 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. One of the intended uses of the body composition meter 1, "I want to gain weight," is associated with display order data for displaying the 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 "not set" purpose of use of the body composition meter 1 is associated with display order data that displays the measurement results in the following order: weight, body fat percentage, visceral fat level, muscle mass, body age, basal metabolic rate, estimated bone mass, and BMI. The display order data is specified to display the order of body composition considered important for each purpose of use.

[0028] Furthermore, in addition to the display order data, advice information with contents corresponding to the intended use is associated with each intended use. As shown in Fig. 4, for example, advice information AD1 is associated with one intended use, "diet." Also, advice information AD2 is associated with one intended use, "get in shape and get fit." Although not shown in the figure, each of the intended uses, "maintain health," "gain weight," and "don't set," is also associated with a specific piece of advice information.

[0029] Furthermore, the storage unit 80 stores a degree of match with respect to the intended use. The degree of match with respect to the intended use is a relationship in which the degree of match with respect to the intended use is associated with a combination relationship of the change direction of a plurality of pieces of body composition data associated with the intended use in the display order. In other words, the relationship is such that, in the order of the body composition data with the highest importance for the intended use, each category of the change direction of the body composition data is associated with the category of the change direction of the body composition data with the next highest importance.

[0030] Fig. 5 shows an example of a usage purpose match degree relationship corresponding to the usage purpose "diet". Note that the usage purpose match degree relationship shown in Fig. 5 is a usage purpose match degree relationship used when a man goes on a diet, that is, a usage purpose match degree relationship for men.

[0031] When the purpose of use is "diet", the degree of matching with "diet" is associated according to the combination relationship of the change direction of "body fat percentage (%)", "internal age", and "basal metabolic rate" which are associated in the display order with "diet". Here, "body fat percentage (%)", "internal age", and "basal metabolic rate" are body composition meter data in order of importance with respect to the purpose of use "diet". That is, the purpose of use matching relationship corresponding to the purpose of use "diet" in this example is a relationship in which, in the order of data related to body composition ("body fat percentage (%)" in this example) with a high importance with respect to the purpose of use "diet", each category of the change direction of the data related to the body composition of the next rank ("internal age" in this example) is associated with each category of the change direction of the data related to the body composition of the next rank ("basal metabolic rate" in this example) and each category of the change direction of the "internal age" is associated with each category of the change direction of the data related to the body composition of the next rank ("basal metabolic rate" in this example).

[0032] As shown in Fig. 5, the degree of matching with "diet" is associated with the combination relationship of the change direction. In this example, the degree of matching is the goal matching evaluation rank associated with the combination relationship of the change direction and the goal matching evaluation data obtained by scoring the goal matching evaluation rank. The goal matching evaluation data is displayed as a body composition change overall evaluation.

[0033] The use purpose matching relationship is further associated with advice information according to the degree of matching with the use purpose. Fig. 6A shows an example of advice information when the use purpose is "dieting", "body fat percentage (%)", "internal age", and "basal metabolic rate" show favorable changes compared to "dieting", and the purpose matching evaluation rank is high (for example, the purpose matching evaluation rank is 1st or 2nd). Fig. 6B shows an example of advice information when the use purpose is "dieting", and the purpose matching evaluation rank is medium, specifically, the "body fat percentage (%)" has decreased but the "basal metabolic rate" has also decreased (the purpose matching evaluation rank is 3rd, 6th, 9th).

[0034] [Example of body composition monitor operation] (About setting mode) Next, an example of the operation of the body composition monitor 1 will be described. First, with reference to the flowchart shown in FIG. 7, an example of the operation of the body composition monitor 1 in a setting mode in which various settings are made to the body composition monitor 1 will be described. The process described below is executed under the control of the control unit 50 in response to an input to the operation unit 30. The setting contents are stored in the storage unit 80. In the following description, information about the user that can be set in the setting mode (such as a personal number, date of birth, and gender information described later) may be referred to as an attribute.

[0035] In step ST1, the touch switch 30c (menu key) is touched, and thereby menu items are displayed on the display unit 17. Then, the process proceeds to step ST2.

[0036] In step ST2, the menu items are switched by the user's operation. The menu items 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 (decision key).

[0037] When menu item (7) (data registration) is set in step ST2, the process proceeds to step ST3. In step ST3, a personal number setting screen is displayed on display unit 17, and the personal number is set. The personal number is an identification number between users (e.g., family members) who use the same body composition meter 1, and is, for example, an integer from 1 to 5. In this case, up to five users can be registered. After the identification number is selected by touching touch switch 30a (up key) or touch switch 30b (down key), the personal number is set by touching touch switch 30d (decision key). Then, the process proceeds to step ST4.

[0038] In step ST4, the user's year of birth is set. The year of birth can be set, for example, by the Gregorian calendar. After the year is selected by touching the touch switch 30a (up key) or the touch switch 30b (down key), the user's year of birth is set by touching the touch switch 30d (decision key). Then, the process proceeds to step ST5.

[0039] In step ST5, the month of birth of the user is set. After the month is selected by touching the touch switch 30a (up key) or the touch switch 30b (down key), the month of birth of the user is set by touching the touch switch 30d (decision key). Then, the process proceeds to step ST6.

[0040] In step ST6, the user's birthday is set. After the day is selected by touching the touch switch 30a (up key) or the touch switch 30b (down key), the user's birthday is set by touching the touch switch 30d (decision key). Then, the process proceeds to step ST7.

[0041] In step ST7, the user's gender is set. After the gender is selected 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 (confirmation key). Then, the process proceeds to step ST8.

[0042] In step ST8, the height of the user is set. After the height (numerical value) is selected 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 (confirmation key). Then, the process proceeds to step ST9.

[0043] In step ST9, the purpose of use of the body composition meter 1 is set. The purpose of use is the purpose for which the user of the body composition meter 1 wants to manage his or her body, and in this embodiment, four purposes of use can be set: "diet," "get in shape," "maintain health," and "gain weight." It is also possible to "not set" the purpose of use. After the purpose of use is selected by touching touch switch 30a (up key) or touch switch 30b (down key), the purpose of use of the body composition meter 1 is set by touching touch switch 30d (decision key). Then, the process proceeds to step ST12, and the process of setting various information is completed.

[0044] The above-described processes of steps ST3 to ST9 are performed as initial registration when the body composition meter 1 is used for the first time after it is purchased, for example.

[0045] In step ST2, when menu item (5) (setting of purpose of use) is selected, the process proceeds to step ST10. In step ST10, a personal number is set. In setting the personal number in step ST10, a personal number whose attributes have already been registered is selected. Once the personal number is selected, the process proceeds to step ST11.

[0046] 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, where the process of setting a new purpose of use or changing the purpose of use is completed.

[0047] By performing the processes of steps ST10 and ST11, even if the purpose of use of the body composition meter 1 is not set at the time of initial registration, it becomes possible to set the purpose of use later. Even if the purpose of use of the body composition meter 1 is set at the time of initial registration, the user can change the purpose of use of the body composition meter 1 in response to changes in life rhythm, etc.

[0048] (About measurement mode) Next, an example of the operation of the body composition monitor 1 in the measurement mode will be described with reference to the flowchart shown in FIG.

[0049] In step ST21, processing related to the measurement mode is started in body composition scale 1 in response to the action of the user standing on top surface 11 of stand 10. In this example, it is assumed that a user whose attributes have been registered stands on body composition scale 1. The personal number, which is one of the attributes, may be input when the user stands on body composition scale 1, or may be automatically recognized by body composition scale 1. Then, processing proceeds to step ST22.

[0050] In step ST22, the body weight and bioelectrical impedance are measured by the body composition meter 1, and various body composition data are measured by calculations using this information. The body composition data measured at this stage is appropriately referred to as the user's current measurement result data. Also, body composition data previously measured by the user and stored in the storage unit 80 is appropriately referred to as past measurement result data. Then, the process proceeds to step ST23.

[0051] 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.

[0052] In step ST24, the control unit 50 refers to the information stored in the memory unit 80 and determines whether or not 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.

[0053] 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.

[0054] In step ST26, the measurement results of the body composition are displayed, and then advice information associated with the intended use is displayed. Then, the process proceeds to step ST32, where the series of processes ends.

[0055] In the determination process of step ST24, if 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 presence status of measurement result data relating to a plurality of past body composition measurements, specifically, the number of past measurement result data stored in the storage unit 80. If there are 2 to 4 past measurement result data, the process proceeds to step ST28.

[0056] In step ST28, the control unit 50 determines an approximation line using past measurement result data measured within a predetermined period as samples. For example, consider an example in which three past measurement result data are stored in the storage unit 80 for each body composition. The control unit 50 determines an approximation line using the three past measurement result data for each body composition. The approximation line is a straight line obtained by plotting the three past measurement result data with the horizontal axis as the time axis and the vertical axis as the measurement result data of the body composition, and applying the least squares method or the like to the plot. Then, the control unit 50 determines the difference between the current measurement result data and the measurement result data on the approximation line corresponding to the present ("current measurement result data" - "measurement result data on the approximation line corresponding to the present"). Then, the process proceeds to step ST29.

[0057] In step ST29, the control unit 50 judges the change tendency for each body composition from the difference obtained in step ST28. For example, the control unit 50 judges the difference to be "no change" if it is within a certain range, judges the difference to be "+change" if it is + and above a certain range, and judges the difference to be "-change" if it is - and above a certain range. The control unit 50 judges the purpose conformity evaluation rank according to the combination relationship of the change tendency for each body composition and the purpose conformity evaluation data obtained by scoring the purpose conformity evaluation rank based on the use purpose conformity relationship. For example, if the change tendency of "body fat percentage (%)" is a negative change, the change tendency of "internal age" is a negative change, and the change tendency of "basal metabolic rate" is a positive change, the purpose conformity evaluation rank is "1st place" and the purpose conformity evaluation data is "100 points" (see FIG. 5).

[0058] In addition, in the process of step ST29, an evaluation (e.g., scoring) of the change tendency is performed for each body composition. For example, with respect to "body fat percentage," if the change tendency based on the difference obtained in step ST28 is "-change," a high score is assigned, if the change tendency based on the difference obtained in step ST28 is "no change," a medium score is assigned, and if the change tendency based on the difference obtained in step ST28 is "+change," a low score is assigned.

[0059] Furthermore, the control unit 50 determines advice information associated with the purpose conformance evaluation ranking and the purpose conformance evaluation data. In the following description, the process of step ST29 is appropriately referred to as "processing B." When the process of step ST29 ends, the process proceeds to step ST30.

[0060] In step ST30, the current measurement result data for each body composition is displayed based on the display order data determined in the above-mentioned process A. Then, the process proceeds to step ST31.

[0061] In step ST31, the control unit 50 displays the goal conformity evaluation data and advice information determined in process B. Then, the process proceeds to step ST32, where the series of processes ends.

[0062] In the determination process in step ST27, if the number of past measurement result data items is five or more, the process proceeds to step ST33.

[0063] In step ST33, the control unit 50 determines an approximation line using past measurement result data measured within a predetermined period as samples. For example, consider an example in which 10 past measurement result data are stored in the storage unit 80 for each body composition. The control unit 50 determines an approximation line using the 10 past measurement result data for each body composition. The approximation line is a straight line obtained by plotting the 10 past measurement result data with the horizontal axis as the time axis and the vertical axis as the measurement result data of the body composition, and applying the least squares method or the like to the plot. Then, the control unit 50 determines the difference between the current measurement result data and the measurement result data on the approximation line corresponding to the present ("current measurement result data" - "measurement result data on the approximation line corresponding to the present"). Then, the process proceeds to step ST29.

[0064] The specific contents of the processing in steps ST29 to ST31 have already been described, so only a brief description will be given. In step ST29, the control unit 50 determines the change tendency for each body composition from the difference obtained in step ST33. The control unit 50 also determines the purpose conformity evaluation rank according to the combination relationship of the change tendency for each body composition and the purpose conformity evaluation data obtained by scoring the purpose conformity evaluation rank based on the use purpose conformity relationship. In the processing in step ST29, the change tendency is evaluated (e.g., scored) for each body composition. The control unit 50 also determines advice information associated with the purpose conformity evaluation rank and the purpose conformity evaluation data. Then, the processing proceeds to step ST30.

[0065] In step ST30, the current measurement result data for each body composition is displayed based on the display order data determined in the above-mentioned process A. The process proceeds to step ST31.

[0066] In step ST31, the control unit 50 displays the goal conformity evaluation data and advice information determined in process B. Then, the process proceeds to step ST32, where the series of processes ends.

[0067] In the determination process in step ST27, if there are not multiple pieces of past measurement result data, in other words, if there is one piece of past measurement result data, the process proceeds to step ST34. In step ST34, the difference between the current measurement result data and one piece of past measurement result data is determined. Then, the process proceeds to step ST29.

[0068] In step ST29, the control unit 50 judges the change tendency for each body composition based on the difference judged in step ST34. For example, the control unit 50 judges the difference judged in step ST34 to be within a certain range as "no change", judges the difference to be "+ change" if it is + and above a certain range, and judges the difference to be "- change" if it is - and above a certain range. Then, the control unit 50 judges the purpose conformity evaluation ranking according to the combination relationship of the change tendency for each body composition and the purpose conformity evaluation data obtained by scoring the purpose conformity evaluation ranking based on the use purpose conformity relationship. In addition, in the process of step ST29, the evaluation (e.g., scoring) of the change tendency is performed for each body composition. In addition, the control unit 50 judges the advice information associated with the purpose conformity evaluation ranking and the purpose conformity evaluation data. Then, the process proceeds to step ST30.

[0069] In step ST30, the current measurement result data for each body composition is displayed based on the display order data determined in the above-mentioned process A. Then, the process proceeds to step ST31.

[0070] In step ST31, the control unit 50 displays the goal conformity evaluation data and advice information determined in process B. Then, the process proceeds to step ST32, where the series of processes ends.

[0071] 9 shows a specific display example of the process in step ST25 described above when "diet" is set as the purpose of use. Since "diet" is set as the purpose of use, the display order data associated with "diet" in FIG. <1> ~ <8> The body composition measurement results data are displayed in the order shown (weight → body fat percentage → body age → basal metabolic rate → visceral fat → muscle mass → estimated bone mass → BMI).

[0072] Fig. 10 shows a specific display example of the process in step ST26 when "diet" is set as the purpose of use. As shown in Fig. 10, advice information AD1 associated with the purpose of use "diet" is displayed on the display unit 17. Note that, since there is no past measurement result data in step ST26 and purpose conformity evaluation data cannot be determined, as shown in Fig. 10, a message is displayed in step ST26 indicating that the specific content of the "overall evaluation of changes in body composition" cannot be determined this time; in other words, a comment C1 is displayed indicating that the "overall evaluation of changes in body composition" will be determined from the next time.

[0073] 11 shows a specific display example of the process in step ST30 described above when "diet" is set as the purpose of use. Since "diet" is set as the purpose of use, the display order data in FIG. <1> ~ <8> The current measurement result data is displayed in the order indicated by (body 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 for each body composition determined in step ST29 is displayed in association with the change trend. That is, if the change trend for body composition is "no change", "→" is displayed next to the display showing the type of body composition, if the change trend for body composition is "+change", "↑" is displayed next to the display showing the type of body composition, and if the change trend for body composition is "-change", "↓" is displayed next to the display showing the type of body composition.

[0074] FIG. 12 shows a specific display example of the process in step ST31 described above when "diet" is set as the purpose of use. As shown in FIG. 12, the control unit 50 displays advice information AD5 in the upper half of the display unit 17. The control unit 50 also displays an item called "overall evaluation of changes in body composition" under the advice information AD5, and displays "90 points" as the purpose conformity evaluation data to the right of the item. The control unit 50 also displays "body fat percentage," "internal age," and "basal metabolism," which are body compositions with high importance for the purpose of use "diet," in descending order of importance under the item called "overall evaluation of changes in body composition." Next to the display showing the type of body composition, an arrow corresponding to the change tendency determined in step ST29, a bar with a length corresponding to the score for each body composition assigned to the change tendency, and a specific score are displayed. In the example shown in Fig. 12, for example, an arrow "↓" indicating a change trend of "-change" is displayed to the right of "body fat percentage", a bar "**********" is displayed to the right of that, and further to the right of that is the score "99 points" assigned to the change trend of "body fat percentage". The higher the score, the further the bar is displayed to the right.

[0075] According to the embodiment described above, it is possible to judge whether the changes occurring in one's body are good or bad 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 specialized knowledge, it is possible to know whether the changes in the body based on the daily life tendency and the direction of effort are suitable for the purpose of use, and it is possible to understand the measurement result with practical meaning. Therefore, not only is it easy to feel the change, but it is also easy to continue the effort and lifestyle improvement toward the goal, so it is effective in maintaining motivation and the body composition meter can be effectively used for guidance in sports gyms, beauty facilities, etc.

[0076] <Modification> Although one embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment, and various modifications are possible within the scope of the technical concept of the present invention.

[0077] Fig. 13 is a diagram showing another example of the use purpose match degree relationship. The example shown in Fig. 13 is an example of the use purpose match degree relationship when the use purpose of the body composition meter 1 is "to train and get fit". In the use purpose match degree relationship for the use purpose "to train and get fit", "muscle mass", "body fat percentage", and "basal metabolic rate" are used as multiple body compositions in order of importance.

[0078] Fig. 14 shows an example of advice information associated with a use purpose matchability relationship in which the use purpose is "I want to train and get toned." Specifically, this is an example of advice information associated with a user's body composition that has not changed much and the purpose matchability evaluation data that is a medium score (for example, a score that corresponds to the 14th place in the purpose matchability evaluation ranking in the use purpose matchability relationship shown in Fig. 13).

[0079] Fig. 15 is a diagram showing another example of the use purpose match degree relationship. The example shown in Fig. 15 is an example of the use purpose match degree relationship when the use purpose of the body composition meter 1 is "maintenance of health". In the use purpose match degree relationship for the use purpose of "maintenance of health", "body fat percentage", "visceral fat level", and "internal age" are used as multiple body compositions in order of importance.

[0080] The example shown in FIG. 16 is an example of the purpose of use match degree relationship when the purpose of use of the body composition meter 1 is "diet". Even if the purpose of use is the same, the purpose of use match degree relationship shown in FIG. 5 is for men, whereas the purpose of use match degree relationship shown in FIG. 16 is for women. When the user is a woman, even if the body fat mass is reduced during the period when the body is swollen, the weight increases, so the body fat percentage in the total body weight does not decrease. In consideration of such a case, it is possible to perform a more appropriate evaluation for women by using "body fat mass" rather than "body fat percentage". Therefore, when the attribute of the individual set in the setting mode is "female", the purpose of use match degree relationship shown in FIG. 16 is used even if the purpose of use is the same. In this way, even if the purpose of use is the same, the purpose of use match degree relationship to be used may be changed depending on the attribute of the individual.

[0081] In the above embodiment, an approximation line based on the measurement result data measured within a predetermined period in the past is determined, and the difference between the current measurement result data and the measurement result data on the approximation line corresponding to the present is determined. The above-mentioned predetermined period may be set by the user. Generally, in order to evaluate whether a change in the body matches a "diet", past measurement result data over a relatively long period is required. However, during that period, the user may behave in a manner contrary to the purpose of use. For example, even if the purpose of use is "diet", there may be a period in which the user binge-eats and drinks. It is preferable to use the measurement result data excluding such periods, that is, the period in which the user was seriously working on a diet. Therefore, the user may be able to set the range of use of past measurement result data (for example, within the past week or a specified date range).

[0082] In the above-described embodiment, if there is a large variance in the past measurement result data, comments such as "The measurement results are not regular" or "It seems like you have a very eventful life. It might be time to reconsider your daily routine" may be displayed.

[0083] In the above-described embodiment, the purpose conformity evaluation data and advice information are displayed after each body composition measurement result data is displayed, but the purpose conformity evaluation data and advice information may be displayed first. Since it takes a certain amount of time to display all body composition measurement result data, the purpose conformity evaluation data and advice information may be displayed to the user first. Also, the purpose conformity evaluation data and advice information may be displayed first, and each body composition measurement result data may be displayed only when a predetermined operation is performed. Also, the user may be able to set whether the purpose conformity evaluation data and advice information or the body composition measurement result data is displayed first. This allows the user to display information that interests him or her first.

[0084] Even if past measurement result data is not stored in the memory unit 80, the current measurement result data may be compared with the average value of the body composition measurement result data for a certain attribute. Then, the change trend may be determined from the difference between the current measurement result data and the average value, and the change trend may be scored and the score may be displayed.

[0085] The information displayed in step S31 may be changed depending on the number of past measurement result data. For example, if there are five or more past measurement result data, step ST31 may display that the reliability of the overall evaluation of body composition change is high. Conversely, if there is only one past measurement result data, step ST31 may display that the reliability of the overall evaluation of body composition change is low.

[0086] The degree of matching associated with the use purpose matching relationship may be something other than the purpose matching evaluation rank or the purpose matching evaluation data, and may be any index indicating the degree of matching. In addition, in the above-mentioned embodiment, the three most important body compositions are used in determining whether or not the use purpose matches (is suitable), but the number may be two or four or more.

[0087] A configuration may be added to the body composition monitor 1 in the above-described embodiment so that it can be held in the left and right hands, and electrodes for the left and right hands may be placed on the parts to be held in the hands, so that impedance can be measured through the hands and feet.

[0088] A configuration different from the configuration shown in Fig. 3 may be added to the body composition scale 1. For example, a communication module that performs close-proximity wireless communication with a mobile device such as a smartphone, or a communication module for connecting to a network such as the Internet may be added to the body composition scale 1. All or part of the calculations performed by the body composition scale 1 may be performed by a smartphone or a server device on the cloud. In addition, the purpose conformity evaluation data and advice information may be played by voice. [Explanation of symbols]
