It is a figure which shows the example of the content of the memory | storage part which concerns on embodiment of this invention. It is a functional block diagram concerning embodiment of this invention. It is a processing flowchart concerning an embodiment of the invention. It is a figure which shows typically the nighttime weight loss change which concerns on embodiment of this invention. It is a figure which shows the nighttime weight loss and the menstrual cycle in association. (A) and (B) are diagrams showing display examples.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following embodiments, the same or corresponding parts are denoted by the same reference numerals in the drawings, and description thereof will not be repeated.

  First, terms are defined. In the present embodiment, “morning time” relating to weight measurement refers to a time zone from 4 am to noon (12:00 noon), for example, and “evening time” refers to a time zone from 7 pm to 2 am, for example. Point to. “Morning weight” refers to the weight measured in the morning time, and “Evening weight” refers to the weight measured in the evening time. In the present embodiment, it is assumed that weight measurement is performed at a certain timing on the wake-up side in the day, and weight measurement is performed at a certain timing on the sleeping side. For the sake of simplicity, it is assumed that the body weight (evening body weight) is measured immediately before entering the bed to go to bed, and the body weight (morning body weight) is measured immediately after waking up. Note that “daytime” refers to a day from the measurement time of the person being measured to the bedtime.

  The “night weight loss” refers to a weight that decreases due to metabolism such as sweating from bedtime to the next wake-up time or excretion after wake-up.

  In the present embodiment, the menstrual start date (the first day of menstruation) is the beginning of the menstrual cycle (first day), and the period from the menstrual start date to immediately before the next menstruation is counted as one menstrual cycle. In the present embodiment, the menstrual cycle is estimated by estimating the menstrual start date.

  In the present embodiment, as a weight management device, a body composition meter capable of acquiring not only body weight but also body composition information such as body fat percentage by measuring bioimpedance is illustrated, but only body weight is measured. It may be a device having the function of

  In this embodiment, the person to be measured measures his / her body weight every morning and evening. Then, the menstrual cycle is estimated based on the characteristics of the change in the weight loss at night based on the measurement data. That is, it is known that the amount of metabolism and the amount of water in the body fluctuate with the menstrual cycle due to the action of secreted hormones. Therefore, the amount of water stored in the body increases and decreases according to the menstrual cycle. More specifically, it is known that during a period of about 2 weeks before the start date of menstruation, the metabolic rate is low and the amount of water in the body is high.

  Since the inventor should have less weight loss at night during the period of about two weeks before the start date of menstruation than at other periods, the inventor should set the menstrual cycle for each subject based on the characteristics of change in weight loss at night. The knowledge that it can be estimated was obtained. Specifically, as shown in FIG. 7 to be described later, it was found that changes in night-time weight loss due to changes in the metabolic amount and water content of the subject can be associated with the menstrual cycle. In the following description, a period of approximately two weeks before the start date of menstruation is abbreviated as “previous two weeks”.

  In the present embodiment, information on the estimated menstrual cycle and information on weight management based on the menstrual cycle are output. Specifically, in the previous two weeks when the metabolic rate is low, no effect can be expected even if dieting (decreasing), so a message prompting you to refrain from dieting is output. Will return, so it outputs a message that the effect of dieting can be expected. Thereby, the menstrual cycle can be estimated for each person to be measured, and information for weight management in light of the estimated menstrual cycle can be presented.

  The operation unit 14 includes a plurality of buttons and switches (see FIG. 1) on which operations such as pressing are performed. The measurement subject can input personal information / physical information of the measurement subject such as ID, sex, age, height, and weight by operating the operation unit 14. The input information is output to the control unit 18.

  Further, in the present embodiment, the menstrual cycle is determined for the measurement subject of the ID only when the ID is input and the predetermined button of the operation unit 14 is operated to designate the weight management function for women. The function for is applied.

  The display unit 15 is configured by a display device such as a liquid crystal screen (see FIG. 1), and displays images such as characters and graphics in accordance with an image signal supplied from the control unit 18.

  The constant current circuit unit 16 causes a high-frequency (alternating current) current supplied from the power source unit 17 to flow in one direction through the electrode unit 21 for current application based on the control of the control unit 18.

The power supply unit 17 supplies operating power to each unit including the control unit 18.
The control unit 18 includes a CPU 181 and a microcomputer (microcomputer) including a ROM (Read Only Memory) and a RAM (Random Access Memory) (not shown), and each unit according to a program and various data stored in the ROM or the like. Control operations and calculation operations are executed.

  The programs and data include programs and data for weight management.

  The double integration AD unit 19 is a double integration type AD conversion unit. In operation, the analog signal (voltage signal) output from the impedance detection unit 20 is converted into a digital signal and output to the control unit 18.

  The impedance detection unit 20 detects the biological impedance of the measurement subject based on the potential difference between the electrode unit 36 provided in the body weight measurement unit 30 and the electrode unit 21 provided in the display operation unit 10.

  The electrode unit 21 is provided on the surface of the grip portion (see FIG. 1) of the display operation unit 10 held by the person to be measured. The electrode unit 21 applies a high frequency (alternating current) current supplied from the power supply unit 17 to the palm of the measurement subject holding the grip portion.

  The weight measurement unit 30 includes an operation unit 31, a battery 32, a load detection unit 33, and an electrode unit 36. The operation unit 31 functions as an input switch operated to switch the power ON / OFF. When the operation unit 31 is operated, the operation unit 31 outputs an input signal corresponding to the operation to the control unit 18.

The battery 32 supplies power to each unit with the power supply unit 17 as the center.
The load detection unit 33 includes a plurality of load cells 34. The body weight of the person to be measured who rides on the upper surface cover part 35 (see FIG. 1) also serving as the upper surface cover of the housing is measured. The measured weight is output to the double integration AD unit 19.

  The electrode unit 36 is provided on the surface of the upper surface portion (see FIG. 1) of the body weight measurement unit 30 on which the measurement subject rides, and is an electrode for current measurement that detects current flowing from the sole of the measurement subject. is there. The electrode unit 36 includes four electrodes that contact the left toe side, the left toe side, the right toe side, and the right toe side of the measurement subject.

  Here, each of the load cells 34 of the load detection unit 33 is disposed below each electrode of the electrode unit 36 so that the load applied to the upper surface portion of the weight measurement unit 30 can be measured. Therefore, when the person to be measured gets on the upper surface part, both the bioimpedance and the weight can be measured.

  In the weight measurement, each load cell 34 is loaded with the weight of the person to be measured. Each load cell 34 includes a strained body made of a metal member that is deformed in accordance with an applied load and a strain gauge stretched on the strained body. When the strain body is distorted, the strain gauge expands and contracts and the resistance value changes according to the expansion and contraction of the strain gauge, and the resistance change is derived as a load signal output. Therefore, when the person to be measured rides on the upper surface portion and both feet are applied to each load cell 34, the weight is measured as the change in the load signal output described above when the strain body is distorted by the weight of the person to be measured applied to the load cell 34. The

  In this embodiment, the load cell 34 is used as a load sensor for detecting a load. However, any load can be used as long as the amount of force applied to the upper surface can be detected, for example, a spring or a piezo film. It may be a sensor using a sensor, an element for detecting compression, a displacement sensor, or the like.

  The server 5 includes a control unit 52, an operation unit 53, a display unit 54, and a storage unit 55 including a computer having a communication unit 51, a CPU 521, a ROM, and a RAM.

  The communication unit 51 transmits / receives data to / from the body weight / body composition meter 3 under the control of the control unit 52. The CPU 521 of the control unit 52 controls the operation of each unit according to a program and data stored in a ROM or the like and executes various calculations.

  The operation unit 53 includes a keyboard and a mouse. A signal input by being operated by the operator is output to the control unit 52.

  The display unit 54 corresponds to a liquid crystal display, a CRT (Cathode Ray Tube) display, or the like. The display unit 54 displays an image such as a picture / character according to a control signal given from the control unit 52.

  The storage unit 55 is a fixed storage device such as a hard disk or a computer of the CPU 521 such as a flexible disk, a CD-ROM (Compact Disk Read Only Memory), a ROM (Read Only Memory), a RAM (Random Access Memory), and a memory card. It corresponds to a readable recording medium.

  The storage unit 55 includes various data related to the subject such as data measured by the body composition meter 3 (body composition information, weight data, measurement date / time data, etc.) and personal information such as the name (ID) and address of the subject. Data is stored.

  In the present embodiment, the bioimpedance can be measured when measuring the body weight of the measurement subject. This makes it possible to calculate and output biometric information (such as body fat percentage) based on bioelectrical impedance along with the body weight. In the present embodiment, in order to simplify the description, description of processing related to calculation and output of biological information based on biological impedance is omitted.

  In the present embodiment, the body composition meter 3 is shared by a plurality of subjects by collecting and processing the measurement data for each subject based on the ID input from the operation unit 14. Can do. Here, in order to simplify the explanation, it is assumed that the weight / body composition meter 3 is dedicated to one female subject.

  Moreover, in this Embodiment, when the predetermined button of the operation part 14 is not operated, normal measurement is performed. That is, the presentation of the weight management information based on the menstrual cycle is omitted, and for example, measurement in which only the measured weight is displayed is performed.

  Referring to FIG. 3, each time the body weight is measured, the storage unit 12 stores an area E1 for storing measurement data and a change amount Vi (i = 1, 2, 3,..., N). Region E2, and region E3 for storing differences DF1, DF2 and DF3 for the past three days. The storage unit 12 stores a threshold value TH and a menstrual cycle date SD. Here, the cycle date SD indicates the menstrual start date (scheduled start date). The difference DFj (j = 1, 2, 3) will be described later.

  Each measurement data stored in the area E1 includes the measured weight data D1, the measurement date / time data D2 based on the timing data of the timing unit 13, and the body weight measurement of “morning time”, “evening time”, and other times. It includes data D3 for distinguishing and indicating in which case it has been implemented.

  The change amount Vi of the area E2 includes nighttime weight loss, date / time data based on the time data output from the time measuring unit 13, and a flag F corresponding to the nighttime weight loss. The flag F is set to “1” when the corresponding weight loss at night is calculated in the previous two weeks, and is set to “0” otherwise.

  The threshold value TH is a threshold value that is referred to in order to determine whether or not the previous two weeks are applicable. The threshold value TH is acquired in advance by an experiment or the like and stored in the storage unit 12 at the time of factory shipment. The cycle date SD indicates the estimated menstruation start date.

  FIG. 4 shows a functional configuration of the CPU 181. Each of these functions is realized by a program or a combination of a program and a circuit. The programs are stored in a predetermined area of the storage unit 12 in advance, and the functions of each unit are realized by the CPU 181 reading out and executing the instruction codes of these programs from the storage unit 12.

  The CPU 181 includes a cycle acquisition unit 182 for estimating a menstrual cycle (more specifically, a menstrual start date and the previous two weeks), a calculation unit 183 for performing various arithmetic processes, and a measurement date and time before the cycle date SD. A cycle determination unit 184 for determining whether the date is a day or a date after the cycle date SD, and an output processing unit 185 for outputting information to the display unit 15 are included.

  The period acquisition unit 182 includes a weight calculation unit 186 for calculating the weight of the measurement subject, a difference calculation unit 187 for calculating the difference DFj, and a change amount calculation unit 188 for calculating the change amount Vi.

  The difference calculating unit 187 calculates a difference between the average value of the nightly reduced weight corresponding to the previous two weeks for the past three months and the nightly reduced weight obtained by the current weight measurement when measuring the nighttime weight. The calculated difference is associated with date / time data based on the timing data output by the timing unit 13 and stored in the region E3 as the difference DFj.

  In the area E3, the difference DFj for a maximum of three days, that is, the differences DF1 to DF3 can be stored. Therefore, every time the difference is calculated, the difference DFj having the oldest associated date / time data (pointing to the past date / time) among the three differences DF1 to DF3 in the region E3 is calculated as the difference DFj calculated this time. Overwritten by and updated.

  With reference to FIG. 5, the process at the time of the weight measurement which concerns on this Embodiment is demonstrated. This process is started when an ON operation of the power supply unit 17 and a predetermined button operation are performed via the operation unit 14. When the process is finished, the CPU 181 turns off the power.

  First, when the person to be measured (female) gets on the weight measuring unit 30, the weight calculating unit 186 calculates the weight based on the output of the load cell 34 (step S3). The measurement data in which the calculated weight data D1, the measurement date data D2 based on the timing data of the timing unit 13, and the data D3 indicating whether the measurement time corresponds to morning time or evening time are associated with each other, It is stored in the area E1 of the storage unit 12 (step S5). Here, the data D3 indicating the distinction between morning and evening includes the data D2 of the measurement date, the morning time (for example, the time zone from 4 am to noon (12:00 noon)), and the evening time (for example, 7 pm to am It is determined on the basis of the comparison result with the 2 o'clock time zone (step S7).

  The data D3 may be determined based on data for distinguishing morning time and evening time, which is input by the measurement subject operating the operation unit 14.

  Subsequently, the cycle acquisition unit 182 determines whether or not the cycle date SD in the storage unit 12 is stored (step S7). Here, when the cycle date SD has not been estimated yet, such as at the time of factory shipment, empty data “NULL” is set in the cycle date SD of the storage unit 12. Therefore, when the cycle date SD is “NULL”, it is determined that there is no cycle date SD. If it is determined that there is no cycle date SD (NO in step S7), the output processing unit 185 displays the weight measured in step S3 on the display unit 15 (step S41), and then the process ends.

  On the other hand, if it is determined that the cycle date SD is not “NULL” (YES in step S5), the cycle determination unit 184 causes the clock data of the clock unit 13 and the evening time (for example, the time zone from 7 pm to 2 am) ) And based on the comparison result, it is determined whether the measurement time corresponds to “evening time” or other time (step S9). This determination may be made based on the data D3 stored in the storage unit 12 in step S5.

  When it is determined that the measurement time corresponds to “evening time” (“evening” in step S9), the period determining unit 184 indicates that the date and time indicated by the time measurement data of the time measuring unit 13 is the date indicated by the periodic date SD of the storage unit 12. It is determined whether or not the previous point is indicated (step S11). If it is determined that it indicates the previous date and time (YES in step S11), the output processing unit 185 displays the cycle date SD read from the storage unit 12 and the weight information measured in step S3 on the display unit 15. It is displayed (step S13). Thereafter, the process ends.

  An example of the display in step S13 is shown in FIG. In (A) of FIG. 8, information on the menstrual cycle of the person to be measured along with the measured weight and information on weight management based on the menstrual cycle (“a period of two weeks ago. Let's refrain because the effect of dieting cannot be expected”) ) Is displayed. In this display, the number of days until the menstrual start date (for example, 10 days) is presented as information related to the menstrual cycle by subtracting the date and time indicated by the timing data of the time measuring unit 13 from the date and time of the cycle date SD. The information regarding the menstrual cycle to present is not limited to this. For example, instead of the number of days until the menstrual start date, the cycle date SD may be displayed, or the number of days until the menstrual start date and the cycle date SD may be displayed.

  If it is determined that the date and time is later than the cycle date SD (NO in step S11), the output processing unit 185 displays the weight information measured in step S3 on the display unit 15 (step S15). Thereafter, the process ends.

  An example of the display in step S15 is shown in FIG. In FIG. 8B, information on weight management based on the menstrual cycle (“there is more than two weeks until the next cycle date. The effect of dieting can be expected”) is displayed together with the measured weight.

  If it is determined in step S9 that the measurement time corresponds to “morning time” (“morning” in step S9), the change amount calculation unit 188 determines the weight of the measurement data immediately before “evening time” from the region E1, that is, The previous day's evening weight data D1 is read and acquired (step S17).

  Subsequently, the change amount calculation unit 188 acquires the night-time weight loss and stores it as the change amount Vi in the area E2 of the storage unit 12 (step S18). That is, the change amount calculation unit 188 calculates the nighttime weight loss by subtracting the morning weight obtained in step S3 from the nighttime weight obtained in step S17, and the calculated nighttime weight loss and the timing unit 13 output Is stored in the area E2 as the change amount Vi associated with the date / time data based on the time measurement data. At this time, the flag F of the change amount Vi is set to “0”.

  Next, the cycle determination unit 184 compares the date and time indicated by the timing data output from the timing unit 13 with the date and time indicated by the cycle date SD in the storage unit 12, and based on the comparison result, the current date and time is determined as the cycle date SD. It is determined whether or not the date is later than the indicated date, that is, whether or not it has passed (step S19). If it is determined that the cycle date SD has not passed, that is, it is a day before the next scheduled menstrual start date (NO in step S19), the change amount calculation unit 188 determines the flag F of the change amount Vi stored in step S18. Is updated to "1" (step S20). Thereafter, the output processing unit 185 displays (B) in FIG. 8 (step S21), and the process ends.

  In this way, when the cycle date SD is updated by detecting the start of the previous two weeks in step S37, which will be described later, thereafter, it is acquired in the period until the cycle date SD passes (that is, the previous two weeks). The flag F of the change amount Vi to be set is set to “1”. Thereby, the change amount Vi acquired in the period corresponding to the previous two weeks can be identified based on the value of the flag F from the change amount Vi of the region E2.

  On the other hand, when it is determined that the current measurement date / time is later than the date / time indicated by the cycle date SD (YES in step S19), the change amount calculation unit 188 acquires the change amount average (step S25). Specifically, among the change amounts Vi for the past three months stored in the area E2, all the night-time weight loss of the change amount Vi with the flag F being “1” is added, and the average based on the addition result Is calculated.

  FIG. 6 schematically shows an average calculation procedure of the change amount Vi. As shown in the figure, the weight at night reduced by subtracting the morning weight from the night weight (however, the corresponding flag F is “1”) is added for a certain period (for example, for the past three months), and the average value is calculated. .

  Here, it is assumed that the change amount Vi of a sufficient number of cases, for example, the change amount Vi for the past three months is already stored in the area E2, but the number of changes Vi is limited to the past three months. What is necessary is just the number which can estimate a menstrual cycle instead of a thing. In order to estimate approximately two weeks before the next menstrual start date, this predetermined period is preferably a period including at least approximately two weeks before the previous menstrual start date.

  In addition, when the change amount Vi of the sufficient number which can estimate a menstrual cycle is not yet stored, let a predetermined value be a change amount average. This predetermined value is an average value of the weight loss at night for the previous two weeks within three months obtained from a plurality of general women. This predetermined value is stored in the storage unit 12 in advance.

  Subsequently, the difference calculation unit 187 acquires the difference between the average amount of change acquired in step S25 and the nighttime weight loss acquired in step S18. Then, the difference DFj that associates the acquired difference with the date and time based on the timing data output by the timing unit 13 is stored in the area E3 (step S27).

  The period acquisition unit 182 determines whether or not the differences DF1 to DF3 for three days are stored in the area E2 (step S29). If it is determined that the difference for three days is not stored (“None” in step S29), a message and information on the weight measured in step S3 are displayed in step S31 (see FIG. 8B). ). Thereafter, the process ends.

  On the other hand, when it is determined in step S29 that the differences DF1 to DF3 for three days are stored (“Yes” in step S29), the period acquisition unit 182 determines the difference DF1 to DF3 and the threshold value TH of the storage unit 12. And compare. Based on the comparison result, it is determined whether or not the conditional expression (difference ≧ TH) is satisfied for each of the differences DF1 to DF3 (step S33). If it is determined that the conditional expression is not satisfied for any of the differences DF1 to DF3 (NO in step S33), the display process in step S31 is performed. In step S31, the information shown in FIG. 8B is displayed.

  If it is determined that the above-described conditional expressions are satisfied for all of the differences DF1 to DF3 (YES in step S33), the cycle acquisition unit 182 calculates the cycle date SD (step S35). Specifically, the oldest (past) date and time is identified from the differences DF1 to DF3, the date two weeks after the identified date and time is calculated, and the calculated date is set as the cycle date SD that is the next menstrual start date. The data is stored in the storage unit 12 (step S37).

  Thereafter, the output processing unit 185 displays the screen of FIG. 8A using the cycle date SD in the storage unit 12 and the weight measured in step S3 (step S39). Thereafter, the process ends.

  Here, in order to determine whether or not the previous two weeks are entered, the difference DF1 to DF3 for three days and the threshold value TH are compared in step S33, but the number of difference DFj to be compared is equivalent to three days. It is not limited to. However, in order to accurately determine whether or not to enter the previous two weeks, it is desirable to use the difference DFj for a plurality of consecutive days.

  In this way, based on the change in the night-time weight loss indicated by the change amount Vi, it is possible to estimate the cycle date SD and the previous two weeks, and to report the information on these estimated menstrual cycles. In addition, it is possible to notify information related to weight management indicating that it is a period that is suitable or unsuitable for weight loss, such as whether or not a diet effect can be expected based on the estimated menstrual cycle.

  The above-described weight management method in the present embodiment can also be provided as a program. Such a program is recorded on a computer-readable recording medium such as a flexible disk, a CD-ROM (compact disk read only memory), a ROM, a RAM, and a memory card attached to the computer of the control unit 18 or the control unit 52. It can also be provided as a program product. Alternatively, the program can be provided by being recorded on a recording medium such as a hard disk built in the computer. A program can also be provided by downloading via a network.

  The provided program product is installed in a program storage unit such as a hard disk, and is read and executed by the CPU 181 (or 521). The program product includes the program itself and a recording medium on which the program is recorded.

(Modification)
The information stored in the storage unit 12 may be transmitted to the server 5, and the received data may be processed by the server 5 so that the information shown in FIG.

  In FIG. 8, the grace period until the estimated cycle date SD is displayed as the information on the menstrual cycle, but the estimated cycle date SD may be displayed together. Further, as shown in FIG. 7, the display unit 15 may display the measurement date, the change in the menstrual cycle / metabolite amount, and the measured change in the weight loss at night, in association with each other.

  In the present embodiment, when the body weight is measured, the information regarding the menstrual cycle is presented as shown in FIG. 8, but even if the body weight measurement is not performed, the cycle date of the storage unit 12 is determined according to the operation of the operation unit 14. Information related to the menstrual cycle based on SD may be displayed.

  In this embodiment, every time the periodic date SD is estimated in step S37, the periodic date SD in the storage unit 12 is updated. However, every time a new periodic date SD is estimated, the storage unit 12 may be additionally stored. In this case, by displaying the cycle date SD of each menstrual cycle and the amount of change Vi in the region E2 in association with each other based on the measurement date and time, a history display as shown in FIG. 7 is possible.
