  This invention is based on the gender, age, height, weight, bioelectrical impedance, etc. of the person being measured for body fat mass (rate), body water content (rate), muscle mass (rate), built-in fat area (level), The present invention relates to a body composition information acquisition system that acquires body composition data such as bone mass, bone density, BCM (Body Cell Mass), and basal metabolism, and more particularly to a body composition information acquisition system that is suitable even when the subject is a child. .

  Based on the gender, age, height, weight and bioelectrical impedance of the person being measured, body fat mass (rate), body water content (rate), muscle mass (rate), internal fat area (level), bone mass, The body composition information acquisition system that acquires body composition data such as bone density, BCM (Body Cell Mass), basal metabolism, etc. (hereinafter simply referred to as “body composition data”) is now widely used in many general households. Have begun to do. In a so-called body scale type body fat scale that is particularly well-known as one type of such body composition information acquisition system, an electrode group for measuring bioelectrical impedance is disposed on the mounting surface of the electronic weight scale. Based on the bioelectrical impedance between both feet measured using, and personal information such as the subject's height, weight, sex, age, etc., using an appropriate regression equation based on the known bioelectrical impedance method, The body fat amount (rate) as the body composition data of the measurer is calculated (for example, see Patent Document 1).

  There is also known a body composition information acquisition system in which an electronic height meter is added to the weight scale body fat scale so that the height can be automatically measured in the same manner as the weight and bioelectrical impedance (for example, patents) See references 2 and 3.) There is also known a body composition information acquisition system in which the calculated body composition data is accumulated and the change history for each day, week, and month can be displayed as a graph (see, for example, Patent Document 4). .

Japanese Patent Publication No. 5-49050 Japanese Patent No. 2835662 JP 2001-252258 A JP 2001-190514 A Japanese Patent Application No. 2003-52410

  Since the conventional body composition information acquisition system as described above is mainly assumed to be an adult as a subject, particularly when the subject is a child, the following various problems occur. Improvement is desired.

  For one thing, these conventional body composition information acquisition systems only display kanji and English characters in the display of the acquired body composition data, or simply display numerical values and graphs that are simple and uninteresting. Or Such a display is, of course, concise and easy to understand for adults, but difficult for children and not interesting.

  It is desirable for children in the process of growth to acquire body composition data continuously using a body composition information acquisition system such as disclosed in Patent Document 4 and Patent Document 5, and observe the change history. Since the displayed body composition data is difficult and intriguing, children may stop using the body composition information acquisition system continuously.

  Therefore, if the display of the acquired body composition data is made easy to understand and enjoyable for children using, for example, hiragana and cartoon-like pictures, it is difficult for adults to view this time, or the acquired body composition data is dignified. This can make it impossible for adults to stop using it continuously.

  Alternatively, in these conventional body composition information acquisition systems, as disclosed in, for example, Patent Document 1 and Patent Document 4, an ideal value and a determination result relating to acquired body composition data are displayed to be measured. There are those that can know the suitability of a person's body composition data and those that can observe the progress of the change by displaying the acquired body composition data in time series.

  However, the ideal values displayed by the conventional body composition information acquisition system and the reference range for determination are usually provided for adults over 18 years of age, so it is helpful for those under 18 years of age including children. In addition, with regard to follow-up, it is natural that the body composition of growing children increases, but the conventional body composition information acquisition system only displays biological information in time series. For this reason, it is not possible to examine the suitability of the increase.

  Of course, the average values for height, weight, and sitting height are published by the Ministry of Health, Labor and Welfare and the Ministry of Education, Culture, Sports, Science and Technology. However, there is no such body composition data such as body fat mass, muscle mass, and bone mass.

Recently, a growth curve of BMI (Body Mass Index: body weight index / height ² ) with respect to age has been published, but in BMI calculated from body weight and height, the body weight is high due to the large amount of muscle mass. There is a fundamental problem that people who are so-called athletes who are heavy are evaluated as obese, and those who are so-called hidden obesity with a small body weight but a large relative body fat are evaluated as appropriate. In addition, especially in the case of a growing child, there is often a large difference in height even at the same age, and the BMI differs greatly between high and low heights. Is said to require attention.

  Therefore, an object of the present invention is to solve the above-described various problems and to provide a body composition information acquisition system suitable even when the measurement subject is a child.

  Next, control processing executed in the body composition information acquisition system 100 will be described with reference to the flowcharts of FIGS. 3 and 4. In addition, an output display example of the monitor screen 32 will be described with reference to FIGS.

  When the user presses any of the personal key switches 17a to 17d of the main body 11, the power of the battery 28 is supplied to each part of the main body 11 via the power supply circuit 27, and the microcomputer 20 corresponds to the pressed personal key switch. A personal number is specified, and control processing according to the flowchart of FIG. 3 is executed.

  First, in step S1, the entire control system of the main body 11 is initialized. With this initialization process, preparations necessary for the subsequent biometric information acquisition process such as zero point correction of the weight scale using the load cell 12 are prepared. At this time, the measurement date data is specified based on the date and time that is measured and updated by the internal clock of the microcomputer 20.

  Next, in step S2, it is confirmed whether or not the current personal number has been registered. Specifically, the microcomputer 20 checks whether or not the user's sex and date of birth corresponding to the current personal number are stored in the EEPROM 26 which is an internal memory, and these data are stored. If this is the case, these data are read out and the process proceeds to step S7 assuming that the current personal number has already been registered. On the other hand, when these data are not stored in the EEPROM 26, it is determined that the current personal number is not registered, and the process proceeds to step S3.

  In step S <b> 3, the microcomputer 20 displays sex input options on the liquid crystal display unit 15, and when a selection input is made from the input switch group 13, the user's sex data is specified based on this input signal.

  Next, in step S4, the microcomputer 20 displays the input option of the date of birth on the liquid crystal display unit 15. When a selection input is made from the input switch group 13, the date of birth of the user is based on this input signal. Identify day data.

  Next, in step S5, the microcomputer 20 stores the gender data specified in step S3 and the date of birth data specified in step S4 in the EEPROM 26 together with the current personal number.

  Next, in step S6, the microcomputer 20 transmits the same data stored in the EEPROM 26 in step S5 to the storage device 1 through the data bus D3 and the terminal 21 together with the personal number. At this time, in the storage device 1, the microcomputer 4 receives these data via the USB terminal 2 and the data bus D1, and stores them in the EEPROM 4 via the data bus D2. When the storage device 1 is detached from the main body 11, this step S6 is skipped.

  Next, in step S7, the microcomputer 20 specifies the age data of the user from the measurement date data specified in step S1 and the birth date data read in step S2 or specified in step S4.

  Next, in step S8, the microcomputer 20 reads the sex data read in step S2 or specified in step S3 and the age data specified in step S7 on the liquid crystal display unit 15 together with input options for affirming or denying them. indicate. When a selection input for affirming these data is performed from the input switch group 13, the process proceeds to step S9, and when a selection input for negation is performed, the process proceeds to step S3.

  In step S <b> 9, the microcomputer 20 displays the height input options on the liquid crystal display unit 15, and identifies the user's height data based on the selection input from the input switch group 13. The height data can be specified, for example, immediately after step S4, and the height data can be registered together with the personal number. However, in this embodiment, a child whose height is changing significantly during the growth process is assumed as the user, and therefore the height data is specified every time the system is used. It is also possible to add a height measuring device such as an electronic height meter using an electronic cursor or infrared rays to the main body 11 and to input the output of such a height measuring device to the microcomputer 20. In such a configuration, height data can be input almost automatically even for a child.

  Next, in step S <b> 10, the microcomputer 20 specifies user weight data based on an input signal from the load cell 12. At this time, a message prompting the user to place both feet in contact with the electrode group 14 and placing it on the upper surface 11a of the main body 11 or a similar symbol or the like is displayed on the liquid crystal display unit 15. If a buzzer or voice guidance is output instead of or in addition to the symbols, the system is easy for children to understand. Further, the weight data may be specified based on the selection input from the input switch group 13 as in the case of the height in step S9, for example. In this case, the load cell 12 and the scale circuit 22 can be omitted.

  Next, in step S11, the microcomputer 20 specifies the bioelectric impedance of the user based on the input signals from the electrode group 14 (particularly, the electrodes 14b and 14d). In this embodiment, the bioelectrical impedance is calculated from the potential difference generated between the user's feet as described above. However, the present invention is not limited to this, and is not limited to this. It may be calculated based on a potential difference generated between the two points.

  Next, in step S12, the microcomputer 20 uses the predetermined regression calculation formulas from the gender, age, height, weight, and bioelectrical impedance data specified so far, and the body fat mass (rate) of the user. Body composition data such as body water content (rate), muscle mass (rate), internal fat area (level), bone mass, bone density, BCM (Body Cell Mass), basal metabolism, etc. are calculated.

  Next, in step S13, the microcomputer 20 determines the measurement date data specified in step S1, the age data specified in step S7, the height data specified in step S9, the weight data specified in step S10, The body composition data calculated in S12 is stored in the EEPROM 26 as an internal memory together with the current personal number.

  Next, in step S14, the microcomputer 20 transmits the same data stored in the EEPROM 26 in step S13 to the storage device 1 through the data bus D3 and the terminal 21 together with the personal number. At this time, in the storage device 1, the microcomputer 4 receives these data via the USB terminal 2 and the data bus D1, and stores them in the EEPROM 4 via the data bus D2. When the storage device 1 is detached from the main body 11, this step S13 is skipped.

  Next, in step S15, the microcomputer 20 alternately displays the height data and weight data specified in steps S9 and S10 and the body composition data calculated in step S12 on the liquid crystal display unit 15 for a predetermined time (for example, 1 minute). Output to display. Thereafter, when such a predetermined time elapses, the power supply from the battery 28 is automatically cut off, and all the control processing in the main body 11 ends.
