Description

[Technical Field]

[0001] The present invention relates to a measuring device for the human body. [Background technology]

[0002] BACKGROUND ART As a method for measuring the body composition of a human body, a measuring device using BIA (Bioelectrical Impedance Analysis), a so-called measuring device, is known (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-220855 Summary of the Invention [Problem to be solved by the invention]

[0004] BIA-based measuring devices measure the electrical resistance of a subject by passing a weak current through the body. The measured electrical resistance, along with other information such as the subject's gender, age, height, and weight, is used to estimate (measure) the subject's body composition. Specifically, the electrical resistance of muscle tissue varies depending on its thickness (cross-sectional area); the larger the cross-sectional area, the lower the electrical resistance; the smaller the cross-sectional area, the higher the electrical resistance. Therefore, the length of muscle tissue is calculated from the measured electrical resistance and pre-entered height, and muscle mass can be estimated by combining the thickness (cross-sectional area) and length. The estimated muscle mass is then used with information such as measured weight, gender, and age to calculate the body fat percentage.

[0005] On the other hand, if the subject has some kind of artificial object on their body, and that object is an insulator, electricity will not flow through that object, and the electrical resistance value will be roughly the same whether or not there is an artificial object. As a result, even though muscle mass due to electrical resistance does not change, the weight will increase by the amount of the artificial object, which creates the problem of not being able to accurately calculate things like body fat percentage. [Means for solving the problem]

[0006] In view of the above problems, the inventors have invented a measuring device that can calculate body composition more accurately than conventional devices, even if the subject of the present invention has some kind of artificial object in their body.

[0007] One embodiment of the measuring device has an electrical resistance value measuring unit that measures the electrical resistance value of one or more parts of the subject's body, and a body composition calculation unit that calculates body composition information of the subject using the electrical resistance value, wherein the measuring device receives information about artificial objects, including at least whether or not an artificial object has been placed in the subject's body, and the body composition calculation unit calculates the body composition information based on the information about the artificial object.

[0008] If a person has an artificial object inside their body, electricity will not flow through it depending on the material. Therefore, although the muscle mass calculated using electrical resistance and height will be roughly the same, the weight of the person will be calculated as an increase in the weight of things that do not conduct electricity, that is, an increase in the weight of fat (which does not conduct electricity), and the body fat percentage (one of the body composition) will be calculated higher than the person's actual state (without artificial objects).

[0009] For example, when something is visible from the outside, like clothing, it is easy to understand that the weight of the clothing can affect body weight and therefore body composition information. However, since artificial objects are placed inside the body, not many people understand that this can affect body composition information. If body composition information is measured without understanding this, accurate body composition information will not be obtained, and people may neglect to measure their body composition.

[0010] Furthermore, since most people who have their body composition measured are wearing clothes, it is possible to set a uniform setting to deduct the weight of clothing. However, whether or not an artificial object is inside the body varies from person to person, so a uniform setting is not possible. Also, unlike clothing, there are cases where the person being measured wants to hide the fact that an artificial object is inside the body from those around them. Therefore, even if an artificial object is inside the body, there are cases where the person being measured wants to obtain accurate body composition information without those around them realizing it.

[0011] On the other hand, if a subject wishes to conceal the fact that they have an artificial object inside their body, they may hesitate to ask the manufacturer or seller of the measuring device about the body composition information measurement results that do not take the artificial object into account, and as a result, they may miss the opportunity to obtain accurate body composition information.

[0012] Therefore, by using the measuring device of the present invention to receive information about an artificial object placed inside the body of the subject and calculating body composition information based on that information, it is possible to calculate body composition more accurately.

[0013] In the above-mentioned measuring device, the information about the artificial object may further include information about the weight of the artificial object, and the body composition calculation unit may calculate the body composition information of the subject using the electrical resistance value and a weight obtained by correcting the measured weight of the subject using at least the information about the weight of the artificial object.

[0014] By configuring the present invention as described above, even if the subject has an artificial object inserted into their body, the influence of the artificial object on the calculation of body composition information can be reduced and the subject's body composition information can be calculated.

[0015] In the above-mentioned measuring device, the body composition calculation unit may calculate the body composition information of the subject using the subject's weight, the weight of the person wearing the body, and the weight of an artificial object inserted into the subject's body.

[0016] When the subject is measured, they will be carrying not only items inside their body but also items on their body (external), such as clothing and accessories, so it is advisable to further correct for the weight of these items.

[0017] In the above-described measuring device, the body composition calculation section may accept input of information relating to an artificial object placed inside the body of the subject when measuring the body weight or when calculating the body composition information.

[0018] In cases where there is a possibility that information about artifacts may change depending on the timing of measurement, as in the present invention, more accurate measurements and calculations can be achieved by accepting input of information about artifacts at the time of measurement or calculation.

[0019] In the above-described measuring apparatus, the body composition calculation section may receive, from a device carried by the subject, input of information relating to an artificial object placed inside the subject's body.

[0020] Some subjects may not want others to know that they have an artificial object inside their body. Therefore, by receiving information about the artificial object from a device carried by the subject, input operations can be omitted and the subject can prevent others from knowing that they have an artificial object inside their body.

[0021] In the above-described measuring device, the body composition information calculated by the body composition calculation section may be sent to the device and stored in the device.

[0022] By sending the body composition information calculated using the corrected weight to the device and storing it, the person being measured can check the body composition information later rather than immediately.

[0023] The above-mentioned measuring device may include an authentication unit that authenticates the person being measured, and a storage means that stores information about the person being measured and the artificial object of the person being measured in association with each other, and the body composition calculation unit may use the identification information of the authenticated person to read out information about the artificial object, and calculate a corrected body weight using the measured body weight of the person being measured and the read-out information about the artificial object.

[0024] This allows the person being measured to avoid the trouble of having to input information about the artifact every time, and also prevents people around the measuring device from knowing that an artifact has been inserted.

[0025] The measuring device may prompt the subject to input the weight of an artificial object placed inside the subject's body.

[0026] The subject may not be aware that the weight of an artificial object placed inside the body affects the calculation of body composition, or may be unaware of this. Therefore, by displaying this information, the subject can be made aware of the need to enter this information.

[0027] In the above-described measuring device, an input of information on the site in the body of the subject where the artificial object is placed or information on the type of the artificial object may be accepted.

[0028] The location or type of artificial object placed may affect the electrical resistance measurement. Therefore, by accepting input of information about the location or type of artificial object placed, body composition information can be calculated more accurately.

[0029] In the above-mentioned measuring device, the algorithm for calculating the body composition information of the subject may be changed or the electrical resistance value may be corrected depending on information about the part of the subject's body where the artificial object is inserted or information about the type of the artificial object.

[0030] When information on the area where the artificial object has been inserted or the type of artificial object is input, the algorithm can be changed or the electrical resistance value corrected accordingly, thereby making it possible to calculate body composition information with greater accuracy.

[0031] The above-mentioned measuring device is equipped with a display unit, and the display unit may display the weight or body composition information of the person being measured as a value different from the corrected weight or body composition information based on the corrected weight, or may not display any value, or may change the display format from normal.

[0032] If the subject's weight corrected for the weight of artificial objects or body composition information based on the corrected weight is displayed as is, people around the measuring device may feel uncomfortable with the weight and body composition information predicted from the subject's physique, etc. Therefore, by processing the display, it is possible to prevent this feeling of discomfort.

[0033] In the above-mentioned measuring device, the display unit may display the subject's uncorrected weight as the subject's weight, and display body composition information calculated using the weight corrected by the body composition calculation unit as the subject's body composition information.

[0034] If a corrected weight, for example, is displayed that differs from the subject's appearance, it may cause discomfort to people around the measurement device. Therefore, by displaying the weight measured before correction and displaying body composition information calculated using the corrected weight, the subject can know a weight that matches their appearance and body composition information based on their own body.

[0035] The measuring device may send the corrected weight or body composition information based on the corrected weight to a device carried by the person being measured.

[0036] If the displayed information is different from the person's appearance, such as corrected weight or body composition information based on the corrected weight, the person will not be able to check the weight or body composition information without artificial objects. Therefore, by sending this information to a device carried by the person, the person can check the information from the device later.

[0037] An information processing device according to one embodiment has an acquisition unit that acquires body composition-related information, and a body composition calculation unit that calculates the body composition information of the subject using the body composition-related information and information regarding artificial objects, including whether or not the subject has placed an artificial object in his or her body.

[0038] The above-described measuring device can be realized by loading and executing one aspect of the program into a computer, that is, the program causes the computer to function as a body composition calculation unit that calculates, from the measured weight of the subject, a weight corrected for at least the weight of an artificial object placed inside the subject, and calculates information on the body composition using the measured electrical resistance value of the subject and the corrected weight.

[0039] The above-described measuring device can be realized by loading and executing one aspect of a program into a computer, that is, the program causes the computer to function as a display unit that, when receiving an input of the weight of an artificial object placed inside the subject's body, displays a corrected weight or a value different from the body composition information based on the corrected weight, does not display any value, or changes the display format from the normal format, with respect to the subject's weight or body composition information. [Effects of the Invention]

[0040] By using the measuring device of the present invention, it is possible to calculate the body composition more accurately than before, even if the subject has some kind of artificial object in their body. [Brief explanation of the drawings]

[Figure 8] 10 is an example of a screen displayed on a device such as a smartphone when the display of the measuring device is as shown in FIG. 7 in Example 4. DETAILED DESCRIPTION OF THE INVENTION

[0042] An example of a schematic configuration diagram of a measurement device 1 according to an embodiment of the present invention is shown in Fig. 1. The measurement device 1 is a device that measures electrical resistance values ​​of the body, such as impedance, reactance, and resistance, by passing a weak current through a subject.

[0043] Measuring device 1 comprises main body 2, right hand grip 3R, and left hand grip 3L. Main body 2 comprises platform 20 on which the subject stands, display 21, weight measurement unit 22, electrical resistance measurement unit 23, body composition calculation unit 24, and memory unit 25. It is preferable to measure the body composition of the subject by standing barefoot on platform 20 and holding right hand grip 3R with the right hand and left hand grip 3L with the left hand, but it is also possible to use only platform 20 without using right hand grip 3R or left hand grip 3L, or to use only right hand grip 3R and left hand grip 3L without using platform 20.

[0044] The platform 20 is equipped with a right-foot current-carrying electrode 201R, a right-foot measurement electrode 202R, a left-foot current-carrying electrode 201L, and a left-foot measurement electrode 202L. The right hand grip 3R is equipped with a right-hand current-carrying electrode 31R and a right-hand measurement electrode 32R, and the left hand grip 3L is equipped with a left-hand current-carrying electrode 31L and a left-hand measurement electrode 32L.

[0045] Display unit 21 is a display device that displays the results of calculation processing by body composition calculation unit 24 and the like, and may be, for example, a liquid crystal display, an organic EL display, or the like, but is not limited to these.

[0046] The weight measurement unit 22 is equipped with a load cell for measuring the weight of the person being measured. The load cell is composed of a strain element made of a metal member that deforms in response to a load, and a strain gauge attached to the strain element. When the person being measured stands on the platform 20, the load of the person being measured causes the strain element of the load cell to bend, causing the strain gauge to expand and contract. The resistance value (output value) of the strain gauge changes in response to this expansion and contraction.

[0047] The electrical resistance value measuring unit 23 measures the electrical resistance value based on the potential difference generated in the current path measured by passing a weak current of a predetermined frequency from each current-carrying electrode to a predetermined part of the subject's body and the current.

[0048] Measurement of electrical resistance values ​​such as impedance (biological impedance) of the subject's whole body and each body part is carried out, for example, as follows. (1) When measuring the bioimpedance of the whole body, current is supplied using the left hand current-carrying electrode 31L and the left foot current-carrying electrode 201L, and the potential difference is measured between the left hand measurement electrode 32L in contact with the left hand and the left foot measurement electrode 202L in contact with the left foot in the current path that flows through the left hand, left arm, chest, abdomen, left leg, and left foot. (2) When measuring the bioimpedance of the right leg, current is supplied using the right hand current-carrying electrode 31R and the right foot current-carrying electrode 201R, and the potential difference between the left foot measurement electrode 202L in contact with the left foot and the right foot measurement electrode 202R in contact with the right foot is measured along the current path that flows through the right hand, right arm, chest, abdomen, right leg, and right foot. (3) When measuring the bioimpedance of the left leg, current is supplied using the left hand current-carrying electrode 31L and the left foot current-carrying electrode 201L, and the potential difference between the left foot measurement electrode 202L in contact with the left foot and the right foot measurement electrode 202R in contact with the right foot is measured along the current path that flows through the left hand, left arm, chest, abdomen, left leg, and left foot. (4) When measuring the bioimpedance of the right arm, current is supplied using the right hand current-carrying electrode 31R and the right foot current-carrying electrode 201R, and the potential difference between the left hand measurement electrode 32L in contact with the left hand and the right hand measurement electrode 32R in contact with the right hand is measured along the current path that flows through the right hand, right arm, chest, abdomen, right leg, and right foot. (5) When measuring the bioimpedance of the left arm, current is supplied using the left hand current-carrying electrode 31L and the left foot current-carrying electrode 201L, and the potential difference between the left hand measurement electrode 32L in contact with the left hand and the right hand measurement electrode 32R in contact with the right hand is measured along the current path that flows through the left hand, left arm, chest, abdomen, left leg, and left foot.

[0049] The electrical resistance value measuring unit 23 may pass a weak current of one frequency, or may pass currents of multiple frequencies such as low-frequency current and high-frequency current. Furthermore, the electrical resistance value to be measured may be not only impedance, but also reactance and resistance, which may be measured separately as electrical resistance values.

[0050] Body composition calculation unit 24 calculates the measured values ​​of the body composition of the whole body and / or each body part by applying a predetermined regression equation to the subject's weight and the electrical resistance measured by electrical resistance measurement unit 23, in addition to the subject's age, sex, and height. The corrected weight of the subject is used in this calculation. That is, the weight of the artificial object attached to the subject's body is corrected by, for example, subtracting the weight of the artificial object from the weight measured by weight measurement unit 22. The weight to be corrected may be input via the touch panel of display unit 21, for example, or may be input from an arbitrary device such as a portable communication terminal such as a smartphone, an activity meter (pedometer), or a card capable of contactless communication, which the subject carries.

[0051] The body composition calculation unit 24 calculates body composition measurements such as fat percentage, fat mass, lean mass, muscle mass, visceral fat mass, visceral fat level, visceral fat area, subcutaneous fat mass, basal metabolic rate, bone mass, total body water percentage, BMI, intracellular fluid volume, and extracellular fluid volume. The processing related to the calculation of body composition measurements can use a configuration similar to that of a general measuring device 1 (body composition analyzer). The subject's age, gender, and height information may be input by the subject, or may be stored in advance in a device carried by the subject, and information input may be received from the device. Furthermore, the subject's age, gender, height, and other information may be stored in the storage unit 25 (described later) and retrieved by a predetermined operation for use in processing.

[0052] For example, if a subject has had breast augmentation surgery using silicone implants, electricity does not flow through the implants. Therefore, the muscle mass calculated using electrical resistance and height is roughly the same for subjects with and without breast augmentation surgery. However, the weight of the subject increases with the addition of the implants. This increases the weight of non-conductive materials, i.e., fat (which does not conduct electricity), and the calculated body fat percentage, a component of the body composition, is higher than the subject's actual state (without implants). Therefore, the body composition calculation unit 24 applies the corrected weight of the subject and the electrical resistance measured by the electrical resistance measurement unit 23 to a predetermined regression equation to calculate accurate body composition measurements for the whole body and / or each body part.

[0053] Body composition calculation unit 24 can be realized by a predetermined arithmetic processing unit in main body unit 2 executing a predetermined computer program.

[0054] The memory unit 25 stores computer programs executed by the arithmetic processing unit in the measuring device 1 of the present invention and information for calculations performed by the computer programs. For example, it stores computer programs for executing regression equations and calculation formulas used in the body composition calculation unit 24, as well as information such as the subject's age, gender, and height. The memory unit 25 is configured with a storage medium such as an SSD or HDD. The memory unit 25 may also be a portable storage medium that is detachable from the main body unit 2. The arithmetic processing unit reads and writes information from the memory unit 25. The display unit 21, the arithmetic processing unit, and the storage device may be integrated into a tablet computer, smartphone, or the like. The computer programs may be stored in the memory unit 25 in advance, downloaded by the arithmetic processing unit via a network, and stored in the memory unit 25, or stored in the memory unit 25 via a portable storage medium.

[0055] The measuring device 1 may have a function for communicating with other information processing devices such as a server. [Example]

[0056] Next, an example of processing when the measurement device 1 of the present invention is used will be described with reference to the flowchart of FIG.

[0057] First, when using measuring device 1, the subject or a third party such as a doctor inputs information about the subject's age, sex, and height, for example, via display unit 21. This input is accepted by body composition calculation unit 24 (S100). This input may be made by the subject themselves, or a third party performing the measurement, such as a medical professional including a doctor, nurse, or clinical laboratory technician, may input the information by asking the subject.

[0058] Then, the person being measured or a third party such as a medical professional inputs the weight of the clothes, accessories, etc. worn by the person being measured (the weight of items worn by the person being measured externally) via, for example, display unit 21. This input is similarly accepted by body composition calculation unit 24 (S110). Note that the weight of the clothes, accessories, etc. of the person being measured may be preset as a fixed weight rather than being input individually.

[0059] Similarly, the subject or a third party such as a medical professional may input, via display unit 21, whether or not the subject has inserted an artificial object, particularly an insulator, into their body, and if the input indicating that the artificial object has been inserted is received, the weight of the artificial object is input. This input is received by body composition calculation unit 24 (S120). An example of an insulator artificial object is a silicone bag.

[0060] The subject sits barefoot on the platform 20 of the measurement device 1, with their right foot positioned on the right-foot current-carrying electrode 201R and the right-foot measurement electrode 202R, and their left foot positioned on the left-foot current-carrying electrode 201L and the left-foot measurement electrode 202L. They also hold the right handgrip 3R with their right hand and the left handgrip 3L with their left hand. The electrical resistance measurement unit 23 passes weak currents of one or more frequencies from each current-carrying electrode to a predetermined part of the subject's body and measures the potential difference generated in the current path. The electrical resistance value is then calculated based on the measured potential difference and current (S130). Furthermore, the weight measurement unit 22 measures the subject's weight (S140).

[0061] The body composition calculation unit 24 subtracts the weight of the subject's clothing, accessories, etc. and the weight of any artificial objects placed inside the subject's body from the weight measured by the weight measurement unit 22, and calculates the subject's corrected weight.

[0062] Then, body composition calculation unit 24 calculates the measured values ​​of the body composition of the whole body and / or each body part by applying the subject's age, sex, height, corrected weight of the subject, and the electrical resistance value measured by electrical resistance value measurement unit 23 to a predetermined regression equation (algorithm) and performing calculations (S150). Note that this algorithm can use not only the regression equation that calculates the value of body composition using the measured electrical resistance value described above, but also a machine learning model that uses the measured electrical resistance value as an input value and outputs the value of body composition as an output value.

[0063] After calculating the body composition, the measured values ​​of the body composition are displayed on the display unit 21 (S160). An example of this display is shown in Fig. 3. In Fig. 3, the body fat percentage calculated using the corrected body weight is displayed.

[0064] Through the above processing, the subject or a third party such as a medical professional performing the measurement can obtain accurate body composition measurements of only the subject's original body parts (only the body parts without artificial objects).

[0065] The input of information, measurement of electrical resistance, and measurement of body weight in the above-mentioned S100 to S120 may be performed in any order. The timing for accepting the input of the weight of the artificial object inside the subject's body in S120 may be any timing, and may be set as appropriate, for example, before, during, or after measuring body weight, before calculating the measured body composition, or when calculating body composition. The subject may be notified of the information by various methods, such as by display on display unit 21, audio, vibration, or the like. [Example]

[0066] The display unit 21 of the measuring device 1 in the above-described first embodiment may display a message prompting the subject or a third party performing the measurement to input the weight of any artificial object placed inside the body. For example, the display unit 21 may prompt the subject to input the weight of any items worn (external) by the subject, such as clothing or accessories, and after receiving this input, prompt the subject to input the weight of any artificial object placed inside the body by a message or the like, and then receive this input. This prevents the subject from forgetting to input the weight of any artificial object placed inside the body. An example of a screen prompting the subject to input the weight of any artificial object placed inside the body is shown in FIG. 4.

[0067] Furthermore, if the subject has an artificial object inside their body, it is possible to accept input of not only the weight of the object but also the part where it is placed. For example, by accepting the subject's selection of the part where the artificial object is placed from an image of the human body, if there is a change in the electrical resistance value depending on the part where the artificial object is placed, it is possible to respond to the change in the electrical resistance value itself at that part. An example of a screen for accepting the selection of the part where the artificial object is placed is shown in Figure 5.

[0068] In addition, input of the type of artifact may be accepted. Depending on the type of artifact, there are artifacts that conduct electricity (conductive artifacts), artifacts that do not conduct electricity (insulating artifacts), and artifacts that are somewhere between conductors and insulators (semiconductor artifacts). Therefore, input of the type of artifact placed by the person being measured may be accepted, and a regression equation according to the type of artifact may be applied or the electrical resistance value may be corrected accordingly. An example of a screen for accepting input of the type of artifact is shown in Figure 6. [Example]

[0069] In each of the above-described embodiments, the information to be input in S100 to S120 is explained as being input by a third party such as the subject or a medical professional, but input may also be unnecessary by storing the information in any device carried by the subject, and having the measuring device 1 receive the information from the device via contact or contactless communication.

[0070] In this case, measuring device 1 may display a button or the like on display unit 21 or the like that enables the correction processing function in body composition calculation unit 24, and the subject may perform a predetermined operation to enable the button, thereby enabling the correction processing function in body composition calculation unit 24. Then, measuring device 1 may be configured to communicate with the device when the device is brought into contact with measuring device 1, or to communicate with the device contactlessly when the device is located within the communication range, receive information from the device in S100 to S120, and automatically perform the correction processing by body composition calculation unit 24.

[0071] Furthermore, if the correction processing function in the body composition calculation unit 24 is enabled but the weight information of the artificial object placed inside the body of the subject is not received from the device carried by the subject, a message may be displayed to prompt the subject to input the type, location, weight, etc. of the artificial object placed inside the body, as in Example 2, and the input may be accepted.

[0072] In the processing of the third embodiment, for example, if the device is a portable communication terminal such as a smartphone capable of near-field wireless communication (NFC), predetermined application software is installed on the smartphone. Information such as the subject's age, gender, height, and the type, location, and weight of any artificial objects placed inside the body is pre-stored in a predetermined storage means referenced by the application software. When the subject stands on the platform 20 and the smartphone is brought close to a predetermined location on the measuring device 1, near-field wireless communication is initiated between the smartphone and the measuring device 1. The subject's age, gender, height, and the type, location, and weight of any artificial objects placed inside the body are read from the storage means referenced by the application software, and the read information is sent to the measuring device 1.

[0073] Upon receiving this information, the measuring device 1 automatically executes a correction process by the body composition calculation section 24 and a calculation process of the body composition by the body composition calculation section 24.

[0074] Furthermore, information such as the subject's age, gender, height, and the type, location, and weight of any artificial objects placed inside the body may be stored in the storage means of the measuring device 1 in association with the subject's identification information. In this case, when the authentication unit (not shown) in the measuring device 1 performs authentication processing to identify the subject, information such as the subject's age, gender, height, and the type, location, and weight of any artificial objects placed inside the body is read from the storage means based on the identification information of the authenticated subject. Based on the read information, the measuring device 1 automatically performs correction processing and body composition calculation processing using the body composition calculation unit 24. Note that information such as the subject's age, gender, height, and the type, location, and weight of any artificial objects placed inside the body may be stored in any storage means, such as a database, a portable communication terminal such as a smartphone, the measuring device 1, or the like. This database may also be stored on the cloud.

[0075] The authentication process to confirm the identity of the person being measured can be performed using biometric authentication, which reads biometric information such as the person's face, fingerprint, or palm print. Various authentication methods can also be used, such as authentication based on an ID and password, or receiving authentication information stored on a portable communication terminal such as a card or smartphone carried by the person being measured.

[0076] By using this type of processing, the person being measured can simply bring their smartphone close to a specified location on the measuring device 1 to execute a body composition calculation process that takes into account the weight of any artificial objects placed inside the body.

[0077] The short-range wireless communication can be realized by various communication standards such as Bluetooth (registered trademark), ZigBee (registered trademark), FeliCa (registered trademark), and RFID. [Example]

[0078] The display unit 21 of the measuring device 1 in each of the above-described embodiments may display a value different from the measured value of body composition calculated by the body composition calculation unit 24 or the weight measured by the weight measurement unit 22.

[0079] For example, any device carried by the subject stores the body composition measurement values ​​and weight information to be displayed on display unit 21. Display unit 21 also displays a button or the like that enables a function to display values ​​different from the pre-correction weight measured by weight measurement unit 22 and the body composition measurement values ​​calculated by body composition calculation unit 24 based on the pre-correction weight, and the subject activates this function by performing a predetermined operation to activate the button. Measurement device 1 then communicates with the device by bringing it into contact with measurement device 1, or by communicating with the device contactlessly by placing the device within the communication range, and receives the body composition measurement values ​​and weight information to be displayed on display unit 21 from the device, and displays the received information from the device on display unit 21 separately from the calculated body composition measurement values ​​and measured weight. This allows display unit 21 to display values ​​different from the calculated and measured values, thereby eliminating any sense of embarrassment or shame felt by the subject.

[0080] When this function is enabled, the display unit 21 may display a different display format than normal, for example, by displaying a predetermined mark M or changing the color, font, or size of letters and numbers, thereby allowing the subject to recognize that information different from the pre-correction weight and the body composition information based thereon is being displayed on the display unit 21. Alternatively, the display unit 21 may display an animated image instead of displaying the body composition measurement value or weight information. In these cases, the subject's device may receive information indicating that the function is enabled, rather than the information to be displayed on the display unit 21. Upon receiving this information, the measuring device 1 may change the display on the display unit 21. An example of a screen in this case is shown in FIG. 7. In FIG. 7, the display format is different from normal, with the mark M displayed, the post-correction weight being displayed, and the body fat percentage being calculated using the post-correction weight being displayed.

[0081] The body composition measurement value based on the pre-correction weight calculated by body composition calculation unit 24, the pre-correction weight information measured by weight measurement unit 22, and information such as height and gender (collectively referred to as "body information") are sent from measurement device 1 to the device, and the person being measured can view the device to learn the pre-correction weight and the body composition measurement value based thereon. In this case, the pre-correction weight and the body composition measurement value based thereon may be stored in measurement device 1. Figure 8 shows an example of a screen displayed on a device such as a smartphone when the display of measurement device 1 is as shown in Figure 7. [Example]

[0082] In the measuring device 1 in each of the above-described embodiments, the display unit 21 may display the weight measured by the weight measuring unit 22, while the body composition calculation unit 24 may display the measured value of the body composition calculated using the corrected weight (weight corrected by subtracting the weight of artificial objects, etc. from the weight measured by the weight measuring unit 22). This allows the weight to be displayed as it appears, and the measured value of the body composition to be displayed as the actual physical measurement of the person being measured. [Example]

[0083] As another example of each of the above-described embodiments, functions such as the body composition calculation unit 24 and the memory unit 25 may not be provided in the measuring device 1. Instead, information about the body composition measured by the measuring device 1 (body composition-related information) may be acquired by an acquisition unit (not shown) and implemented as an application program in an information processing device other than the measuring device 1, such as a computer including a portable communication terminal such as a smartphone or tablet computer, or a server. The body composition-related information includes one or more of electrical resistance value, body weight, and body composition information calculated using these. As an example, the measuring device 1 may include a weight measurement unit 22 and an electrical resistance value measurement unit 23. The uncorrected body weight measured by the weight measurement unit 22, the electrical resistance value measured by the electrical resistance value measurement unit 23, and information about artificial objects are acquired by the information processing device, and the body composition calculation unit 24, etc., implemented by the application program of the information processing device, executes processing similar to that described above. The information about artificial objects may be acquired by the acquisition unit or may be stored in advance in the information processing device.

[0084] As another example of the above, body composition calculation unit 24 calculates a body composition measurement value based on the pre-correction weight using the pre-correction weight measured by weight measurement unit 22 of measurement device 1 and the electrical resistance value measured by electrical resistance measurement unit 23. Then, the body composition measurement value based on the pre-correction weight is acquired by an acquisition unit of the information processing device from measurement device 1, and body composition calculation unit 24, implemented by an application program of the information processing device, may be configured to accept input of information on the weight of an artificial object placed inside the subject's body and correct the acquired body composition measurement value based on the pre-correction weight using the information on the weight of the artificial object. In this case, body composition calculation unit 24 may pre-store a regression equation that calculates a corrected body composition measurement value using the body composition measurement value based on the pre-correction weight and the information on the weight of the artificial object, and calculate a body composition measurement value corrected using the information on the weight of the artificial object using the regression equation. [Industrial Applicability]

[0085] By using the measuring device 1 of the present invention, it is possible to calculate the body composition more accurately than before, even if the subject has some kind of artificial object in their body. [Explanation of symbols]
