Description

Body fat measuring method and body fat measuring equipment

The present application claims priority from the chinese patent application filed on 3/5/2017 under the name of "a method and apparatus for measuring body fat" by the chinese patent office having application number 201710305773.4, the entire contents of which are incorporated herein by reference.

Technical Field

The application relates to the field of terminals, in particular to a body fat measurement method and body fat measurement equipment.

Background

4600 million people in China "obese" and 3 hundred million people "overweight" in 2015. Fifty percent of type 2 diabetes, thirty percent of ischemic cardiovascular and cerebrovascular diseases, and ten to forty percent of cancer are caused by obesity or being overweight. The first four causes of death, which are about ten of the causes of death published by the Wei Ji committee, are highly related to obesity. Both obese and overweight people in modern life need to lose weight for a healthy life. However, obesity is equivalent to an excessively high fat rate, i.e. weight loss is equivalent to fat loss rather than weight loss. When losing weight, the fat rate can reflect the weight losing effect and whether the weight losing direction is correct or not better than the weight. In order to scientifically lose weight, the body fat of each part of the whole body needs to be known, and then targeted scientific body building is carried out on the obese part.

In order to obtain body fat rate of various parts of the body, people usually purchase tools such as body fat scales to measure body fat in daily life. However, the current body fat scale and other tools can only measure fixed parts due to the measurement mode, for example, as shown in fig. 1(a), only upper limbs can be measured by using a Tomtom bracelet; as shown in fig. 1(b), only the lower limb can be measured using a general body fat scale (only the impedance between both feet can be measured); as shown in fig. 1(c), only the whole body can be measured using an Inbody body fat scale (the impedance between both hands and the impedance between both feet can be measured). Therefore, the user can only measure the fixed part and cannot flexibly measure the body fat rate of different parts of the body according to the user requirement.

It is understood that, when measuring the whole body fat, the body fat measuring apparatus can also calculate the body fat of the upper limb, the abdomen, and the lower limb of the human body, respectively.

In this embodiment, when this body fat measuring equipment is intelligent bracelet or intelligent wrist-watch and measuring electrode fixes on this intelligent bracelet or intelligent wrist-watch. The structure may be as shown in fig. 8, wherein the body fat measurement device 800 comprises at least two electrodes, the first electrode 801 is located in an inner ring of the body fat measurement device 800, and the second electrode 802 is located in an outer ring of the body fat measurement device 800. For example, when the body fat measurement device is a smart watch, the first electrode may be located on a front and back surface of a dial of the smart watch, and then the second electrode may be located on an outer ring of the smart watch facing the front and back surface of the dial. Wherein the first electrode and the second electrode both have a measuring function. In practical application, the function of the first electrode can be realized by division of the driving electrode and the measuring electrode, and can also be realized by one electrode. The same is true for the second electrode. Meanwhile, the body fat measuring device may also comprise a plurality of electrodes as long as the measurement requirements are met, and the specific number is not limited here.

202. And the body fat measuring equipment measures the impedance between the measurement reference point and each point to be measured in the point set to be measured according to a preset sequence.

The body fat measuring device measures impedance between the measurement reference point and each point to be measured in the point set to be measured according to a preset sequence.

Taking the measurement point set shown in fig. 3 as an example, the measurement reference point is the measurement point with the reference number 7, and each point to be measured is the measurement point with the reference numbers 1 to 6. The preset sequence may be, in order: the measurement point marked 7 and the measurement point marked 1; the measuring point with the reference number 7 and the measuring point with the reference number 2; the measuring point with the reference number 7 and the measuring point with the reference number 3; the measuring point with the reference number 7 and the measuring point with the reference number 4; the measuring point marked 7 and the measuring point marked 5; the measuring point denoted by 7 is compared with the measuring point denoted by 6. Of course, the preset sequence may also be in other possible manners, and the specific manner is not limited herein.

In this embodiment, a measurement schematic diagram of the body fat measurement device is shown in fig. 9: this skin layer corresponds to the resistance shown in fig. 9; then the two driving electrodes generate current, and a current loop is formed between the skin layer and the two measuring electrodes; then a voltmeter between the two measuring electrodes measures the divided voltage of the skin layer; and finally, solving the resistance (namely the impedance) of the skin layer according to the relation among the current, the resistance and the voltage.

In this embodiment, when measuring impedance, the body fat measurement device needs to ensure that at least two electrodes on the body fat measurement device are respectively in contact with the measurement reference point and the point to be measured. When the body fat measuring device is worn on the left hand as shown in fig. 10 and the impedance between the measuring point with the reference number 7 and the measuring point with the reference number 1 needs to be measured, the measuring electrodes on the body fat measuring device located on the outer ring are only required to be in contact with the measuring electrodes on the right hand with the reference number 1 (the two hands intersect in fig. 10) because the wrist of the left hand has been in contact with the measuring electrodes on the inner ring of the body fat measuring device. Similarly, when other points to be measured need to be measured, the left hand is moved and closed to the other points to be measured, so that the measuring electrode positioned on the outer ring of the body fat measuring equipment is in contact with the points to be measured.

In this embodiment, the measurement process may be performed in the following ways according to different body fat measurement devices:

in one possible implementation, the body fat measurement device is a smart watch (which possesses a display) as shown in fig. 11. The measurement process of the body fat measurement device may then be as follows: firstly, after the body fat measurement is started by the intelligent watch, a prompt message for measuring the body fat can be displayed on a display screen of the intelligent watch. It is to be understood that the smart watch may initiate the body fat measurement by a touch action on the body fat measurement icon; or the body fat measurement may be initiated by voice, in a manner not limited herein. Then, while the smart watch is measuring, an image indicating that measurement is taking place is displayed on the display screen. Finally, after the body fat measurement is completed, the smart watch may display the last measurement on the display screen. It can be understood that the smart watch may also prompt the measurement result by means of voice prompt, and the specific manner is not limited herein. In this embodiment, when the smart watch is measuring, the image on the display screen for indicating that the smart watch is measuring may be displayed by a text of "… … in measurement" or may be displayed by a progress bar, and a specific manner is not limited herein as long as it can indicate that the smart watch is measuring. In practical application, the body fat measuring device can directly start measurement as long as the measuring electrodes of the inner ring and the measuring electrodes of the outer ring are both contacted with the skin (here, the skin can be contacted with the skin through clothes); it may also be desirable to start the measurement after the measurement function has been initiated. When the body fat measurement device starts measurement after the measurement function is started, the body fat measurement device may prompt the user if the on time is too long and no measurement is performed or the measurement time is too long and the user wants to stop the measurement. Specific modes include but are not limited to at least one of vibration, ringing, voice prompt or display prompt information. For example, when the body fat measurement device includes a display screen, a screen as shown in fig. 12 appears on the display screen of the body fat measurement device. In fig. 12, the measurement is suspended when the user selects "yes", and the measurement is continued when the user selects "no". It should be understood that fig. 12 only shows one display manner, and in practical applications, the specific display manner is not limited herein as long as the function shown in fig. 12 can be implemented. It is understood that, in practical applications, if the user does not perform the measurement for a long time after the measurement function is turned on, the body fat measurement device may directly stop the measurement and display a prompt message on the display screen. Such as directly displaying "stopped measurement". And if the user needs to measure again after seeing the prompt message, restarting the measurement function.

In another possible implementation manner, the body fat measurement device includes a smart band without a display screen as shown in fig. 13, and a terminal connected to the smart band. In this embodiment, the terminal includes, but is not limited to, a mobile phone, a tablet, and the like. The measurement process of the body fat measurement device can now be as shown in fig. 13: firstly, the mobile phone controls the smart band to start a measurement function or starts the measurement function through a function button which is arranged on the smart band and starts the measurement function, and then prompt information for measuring body fat can be displayed on the mobile phone; then when the smart band is measuring, displaying an image for representing processing on the mobile phone; and finally, after the measurement of the intelligent bracelet is completed, displaying the final measurement result on the mobile phone. In this embodiment, when the smart band is measuring, the image used for indicating that the measurement is being performed on the mobile phone may be displayed by a text of "… … in measurement" or may be displayed by a progress bar, and a specific manner is not limited herein as long as it can indicate that the measurement is being performed. In practical application, the body fat measuring device can directly start measurement as long as the measuring electrodes of the inner ring and the measuring electrodes of the outer ring are both contacted with the skin (here, the skin can be contacted with the skin through clothes); it may also be desirable to start the measurement after the measurement function has been initiated. When the body fat measurement device starts measurement after the measurement function is started, the body fat measurement device may prompt the user if the on time is too long and no measurement is performed or the measurement time is too long and the user wants to stop the measurement. The specific mode can include but is not limited to at least one of vibration, ringing, voice prompt, vibration, ringing, voice prompt or prompt message sent by the mobile phone. For example, a screen as shown in fig. 14 appears on the display screen of the mobile phone. In fig. 14, the measurement is suspended when the user selects "yes", and the measurement is continued when the user selects "no". It should be understood that fig. 14 only shows one display manner, but in practical applications, the specific display manner is not limited herein as long as the function shown in fig. 14 can be implemented. In practical application, if the user does not measure for a long time after starting the measurement function, the body fat measurement device can also directly stop measuring and display prompt information on a display screen of the mobile phone. For example, as shown in fig. 15, "measurement stopped" is directly displayed. And if the user needs to measure again after seeing the prompt message, restarting the measurement function. Meanwhile, the user can be reminded that the measurement is stopped by means of voice, ringing and the like.

203. The body fat measuring equipment stores the measurement reference point, the points to be measured and the impedance between the measurement reference and the points to be measured as a mapping relation table.

The body fat measuring equipment establishes a one-to-one mapping relation table for the impedance between the measurement reference point and each measurement point, and then stores the mapping relation table.

In this embodiment, the mapping relationship table may be as shown in table 1:

reference point for measurement	Point to be measured	Impedance/ohm
7	1	300
7	2	100
7	3	800
7	4	800
7	5	100
7	6	25

TABLE 1

In this embodiment, the part to be measured, which is formed by combining the measurement reference point and different points to be measured, and the corresponding calculation formula may also be stored as a mapping relationship table, as shown in table 2:

TABLE 2

In this embodiment, the body fat measurement device may store the table 1 and the table 2 in advance for recall when measuring again.

In this embodiment, steps 201 to 203 are preset procedures in the first measurement procedure of the body fat measurement device. In practical applications, for example, the smart band is used, the process of presetting may be as shown in fig. 16, where the mobile phone prompts the user to perform presetting before the first measurement is performed, and when the user clicks certain, the preset process is entered. Firstly, the mobile phone prompts a user to select a measurement reference point and a point set to be measured, and then the next step is clicked; then entering an interface for determining a measurement sequence, and clicking the next step after determining the measurement sequence; and finally entering a measurement interface. In this embodiment, when the user determines the measurement reference point and the set of points to be measured, the user may manually input the measurement reference point and the set of points to be measured, or may select the measurement reference point and the set of points to be measured in a drop-down box, and a specific manner is not limited here. Similarly, the user may use the same method in determining the measurement sequence. Meanwhile, in the process of the first measurement of the body fat measurement device, the body fat measurement device can also calculate the body fat of each measurement part of the user in the first measurement process according to a preset formula, and then store the body fat of each measurement part of the user as initial comparison data. In this embodiment, if the measurement reference point is the measurement point denoted by reference numeral 7 shown in fig. 3, and the set of points to be measured is the measurement point denoted by reference numeral 1 to the measurement point denoted by reference numeral 6 shown in fig. 3, the preset formula includes:

the formula of the body fat weight of the upper limb is as follows: m1 ═ Z71 × P1+ Z76 × P2+ C1;

the formula of the weight of the body fat of the abdomen is as follows: m2 ═ P3+ (Z75-Z76) × P4+ C2 (Z72-Z76);

the body fat weight formula of the lower limb is as follows: m3 ═ P5+ (Z74-Z75) × P6+ C3 (Z73-Z72);

the body fat ratio formula of the whole body is as follows: u ═ Z (P1 × Z71+ P2 × Z72+ P3 × Z73+ P4 × Z74+ P5 × Z75+ P6 × Z76+ C4)/m;

wherein m1 is the body fat weight of the upper limb; m2 is the body fat weight of the abdomen; m3 is the body fat weight of the lower limb; u is the body fat rate of the whole body; the Z71 is the impedance between the measurement point labeled 7 and the measurement point labeled 1; z72 is the impedance between the measurement point labeled 7 and the measurement point labeled 2; z73 is the impedance between the measurement point labeled 7 and the measurement point labeled 3; z74 is the impedance between the measurement point labeled 7 and the measurement point labeled 4; z75 is the impedance between the measurement point labeled 7 and the measurement point labeled 5; z76 is the impedance between the measurement point labeled 7 and the measurement point labeled 6; the P1, P2, P3, P4, P5 and P6 are preset coefficients; the C1, C2, C3 and C4 are preset constants; the m is the user's weight. Assuming that the weight of the user is 120 jin during the initial measurement, and the measured body fat percentage of the whole body is 27%, the weight of the whole body fat is 32.4 jin; wherein the weight of the upper limb is 3 jin, the weight of the abdomen is 18 jin, and the weight of the lower limb is 11.4 jin.

Optionally, in this embodiment, the steps 201 to 203 may not be executed, and after the user starts the measurement function or the body fat measurement device has acquired the impedance between two measurement points, as shown in fig. 17, the display screen of the body fat measurement device or the display screen of the terminal in the body fat measurement device may display the corresponding information of the combination of the measurement reference point and the point to be measured and the part to be measured. Therefore, the user can be directly informed to select the point to be measured and the measurement reference point after determining which part to measure, the use by the user is more convenient, and the user experience is improved. Of course, it is also possible to select to display the part to be measured through the first interface as shown in fig. 18 after the user starts the measurement function or has measured and acquired the impedance between two measurement points, and then to display the corresponding second interface after clicking the part to be measured. If the user clicks "measure upper body fat" in fig. 18, the corresponding second interface is as shown in fig. 19; if the user clicks "measure abdominal body fat" in FIG. 18, the corresponding second interface is as shown in FIG. 20; if the user clicks "measure lower limb fat" in FIG. 18, the corresponding second interface is as shown in FIG. 21; if the user clicks "measure full body fat" in fig. 18, the corresponding second interface is as shown in fig. 22. It is understood that, in this embodiment, in the process that the body fat measurement device has acquired the impedance between two measurement points, the two measurement points may be any point of the human body, as long as the impedance can be acquired, and the method is not limited specifically.

It can be understood that the body fat measuring device can also prompt the combination of the measuring reference point and the point to be measured and the corresponding information of the part to be measured through voice prompt. For example, after the user starts the measurement function or has measured and acquired the impedance between two measurement points, the body fat measurement device may prompt with voice "please select the measurement site, 1, the upper limb; 2, abdomen; 3, the lower limbs; 4 whole body ". Then, after the user selects a measurement site by inputting numbers, the body fat measurement device prompts the measurement point and the measurement reference point by voice. For example, if the user selects to measure the upper limb, the user inputs the number "1", and at this time, the body fat measurement apparatus may voice-prompt "the measurement reference point is a point located at the right-hand wrist, and the points to be measured are a point located at the left-hand wrist and a point located at the chest". Finally, when the user completes the measurement, the body fat measurement device may prompt the body fat at the measurement site by voice.

204. The body fat measuring equipment measures and acquires impedance between the measurement reference point and a target point to be measured, the target point to be measured is contained in the set of points to be measured, and the measurement reference point and the target point to be measured indicate a part to be measured.

The body fat measuring apparatus acquires a target point to be measured when measuring again, and then measures the impedance between the measurement reference point and the target point to be measured.

In this embodiment, if the body fat measurement device performs the preset process from step 201 to step 203, the body fat measurement device may determine the part to be measured according to the impedance between the measurement reference point and the target point to be measured. For example, if the body fat measurement device measures the impedance between the measurement point labeled 7 and the target point to be measured includes: 300 ohms, 25 ohms; then, as can be seen from table 1, the target points to be measured by the body fat measuring apparatus are the measuring point with the reference number 1 and the measuring point with the reference number 6; then, as can be seen from table 2, the body fat weight of the upper limb was measured by the body fat measuring apparatus; and finally, the upper limb body fat weight calculation formula and the 300 ohm and 25 ohm calculation are used for obtaining the upper limb body fat weight of the user.

If the body fat measurement device does not perform the preset process from step 201 to step 203, by directly displaying the combination of the measurement reference point and the point to be measured and the corresponding information of the part to be measured, the body fat measurement device acquires the information of the part to be measured before measuring the impedance of the measurement reference point and the target point to be measured. For example, it is known at the beginning of the measurement that the impedances between the measurement point labeled 7 and the measurement points labeled 1 and 6, respectively, need to be measured, resulting in impedances of 300 ohms and 25 ohms, respectively; then, the upper limb body fat weight calculation formula and the 300 ohm and 25 ohm calculation are called to obtain the upper limb body fat weight of the user.

205. The body fat measuring device calculates the body fat rate of the part to be measured by using a preset formula and the impedance between the measurement reference point and the point to be measured.

The body fat measuring equipment acquires a preset formula corresponding to the part to be measured, and then calculates the body fat rate of the part to be measured by using the preset formula and the impedance between the measurement reference point and the target point to be measured.

In this embodiment, if the measurement reference point is the measurement point denoted by reference numeral 7 shown in fig. 3, and the set of points to be measured is the measurement point denoted by reference numeral 1 to the measurement point denoted by reference numeral 6 shown in fig. 3, the preset formula includes:

wherein m1 is the body fat weight of the upper limb; m2 is the body fat weight of the abdomen; m3 is the body fat weight of the lower limb; u is the body fat rate of the whole body; the Z71 is the impedance between the measurement point labeled 7 and the measurement point labeled 1; z72 impedance between the measurement point labeled 7 and the measurement point labeled 2; z73 impedance between the measurement point labeled 7 and the measurement point labeled 3; z74 impedance between the measurement point labeled 7 and the measurement point labeled 4; z75 impedance between the measurement point labeled 7 and the measurement point labeled 5; z76 impedance between the measurement point labeled 7 and the measurement point labeled 6; the P1, P2, P3, P4, P5 and P6 are preset coefficients; the C1, C2, C3 and C4 are preset constants; the m is the user's weight.

In practical application, after the body fat of the part to be measured is measured, the body fat measuring device can prompt the measurement result to a user, and meanwhile exercise opinions can be given in a targeted mode. Specific ways include, but are not limited to, at least one of voice prompts or displaying results on a display screen. In this embodiment, the terminal display is taken as an example, and a specific manner may be as follows, when the user selects to measure the upper body fat, the measurement result and the exercise suggestion displayed on the mobile phone screen may be "when the weight of the front body fat is 3 jin as shown in fig. 23; the body fat is normal, please maintain! "; when the user selects to measure the abdominal body fat, the measurement result and exercise suggestion displayed on the mobile phone screen may be "when the weight of the front body fat is 18 jin as shown in fig. 24; the body fat is higher, and 10 jin of fat is recommended to be reduced, so that two-month fitness courses are set for you to carry out targeted abdomen fat reduction. "; when the user selects to measure the lower body fat, the measurement result and exercise suggestion displayed on the mobile phone screen can be as shown in fig. 25 "when the weight of the front body fat is 11.4 jin; the body fat is higher, and 6.4 jin of fat is recommended to be reduced, so that the targeted lower limb fat reduction is carried out for the two-month fitness course set for you. "; when the user selects to measure the whole body fat, because all the measurement points are measured, the body fat measurement device can calculate the whole body fat of the user and the weight of the body fat of each individual part, so the measurement result and the exercise suggestion displayed by the mobile phone screen can be that "the current body fat rate is 25%, the weight is 120 jin, and the body fat is 32.4 jin as shown in fig. 26; the weight of the fat of the upper limb is 3 jin, the weight of the fat of the abdomen is 18 jin, and the weight of the fat of the lower limb is 11.4 jin; weight loss of 16.4 jin is recommended, and two-month fitness courses are set for you to perform targeted abdominal and lower extremity fat reduction. "

In this embodiment, the body fat measurement device may store the measurement result of each time of the user, compare the measurement result of each time with the measurement result of the last time, and then give feedback. For example, taking the smart bracelet as an example, if the measurement result obtained when the user measures the abdominal body fat for the first time is "the current body fat weight is 18 jin; the body fat is higher, and 10 jin of fat is recommended to be reduced, so that two-month fitness courses are set for you to carry out targeted abdomen fat reduction. "; after the user exercises according to the two-month fitness course, the measurement result obtained by measuring again is' when the weight of the front body fat is 15 jin; the body fat is higher, and 7 jin of fat is recommended to be reduced, so that a one-month fitness course is set for you to carry out targeted abdomen fat reduction. ". The handset can then give a feedback word as shown in figure 27. When the user exercises according to the fitness course of the month, the measured result obtained by measuring again is that the current body fat weight is 11 jin; the body fat is higher, and 3 jin of fat is recommended to be reduced, and one month of fitness course is set for you to carry out targeted abdomen fat reduction ". The handset may then give a feedback word as shown in figure 28. When the user exercises according to the fitness course of the month, the measured result obtained by measuring again is that the current body fat weight is 8 jin; if body fat is normal, please maintain. ". The handset can then give a feedback word as shown in figure 29.

In this embodiment, the fitness course may be set according to the actual situation of the user, for example, before measurement, the user may be evaluated for fitness habits at ordinary times. If the evaluation result shows that the user has good fitness habits (such as always exercising or rich fitness knowledge) the user can provide a more difficult fitness course when the fitness course is recommended; if the evaluation result shows that the user has no fitness habit (such as initial contact with fitness or less fitness knowledge) the fitness course can be recommended, so that the fitness course which is simpler and easier to implement is provided. For example, when an abdominal fat reduction course is recommended, if the body fat measurement device determines that the user has good fitness habits, the following fitness courses may be recommended to the user: rising two ends of each leg in a supine way, alternately turning the beetles in a supine way, bending knees in a supine way and lifting hips and lifting knees and abdomen on one side; if the body fat measurement device determines that the user has a good fitness habit, the following fitness course can be recommended for the user: turning and twisting waist, touching knee coil, climbing mountain and supporting leg lifting with flat plate in sitting posture; if the body fat measurement device determines that the user is not in fitness habit, the following fitness course can be recommended for the user: alternately contacting heels on the back, alternately contracting knees on opposite angles on the back, bending knees on the back, lifting legs to rotate waist and lifting legs to roll abdomen on the side. In this embodiment, the fitness course may be directly displayed on the display screen of the body fat measurement device, or may be sent to a mailbox or a social account of the user, so that the user may look up the fitness course. The specific manner is not limited herein.
