Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subcutaneous fat meter for measuring a subcutaneous fat thickness, a body fat percentage and the like by digital values.

[0002]

2. Description of the Related Art In recent years, attention has been focused on managing body fat percentage instead of simply managing body weight in health management. As a method for measuring the body fat percentage, a method in which a weak current is applied to the body of the subject and the electrical resistance is measured to obtain the body fat percentage (electric resistance type),
There are those that measure the thickness of subcutaneous fat at a predetermined part of the body and estimate it from the value (fat thickness formula) and those that measure the specific gravity of the body and estimate it from the value. Among them, the electric resistance type and the fat thickness type are generally used from the viewpoint of simplicity and the price of a measuring instrument.

[0003]

However, it is difficult to reduce the size of an electric resistance type measuring instrument because an electrode in contact with the body must have a certain area.
If the electrodes are made of metal, the weight cannot be reduced. Further, the obtained electric resistance value is affected by sweating, the contact area with the electrode, and the like, so that it is difficult to obtain a stable measured value. In order to stabilize the measured value, it takes time and effort to apply a conductive paste or the like to a portion in contact with the electrode. Further, the price is high due to the complexity of the device configuration.

The fat-thickness measuring instrument is a simple instrument, but simply measures fat thickness. Therefore, it is necessary to obtain a conversion formula and a table for obtaining the body fat percentage from the measured values. In addition, it takes time to convert the fat thickness into the body fat percentage. Furthermore, since the thickness of the soft tissue called fat is mechanically measured, the measured value may fluctuate depending on the force applied to the measuring instrument. For this reason, it is difficult for a person to measure by himself / herself, and even though it is a simple measuring instrument, the measurement itself cannot be said to be easy.

As described above, the conventional fat meter cannot easily obtain a stable measured value. Further, it is not that the subject himself / herself can easily measure by himself.

The present invention has been made in view of the above conventional example, and has as its object to provide a subcutaneous fat meter which can obtain a stable measurement value and can be easily measured by a subject alone.

[0007]

In order to achieve the above object, a subcutaneous fat meter according to the present invention has the following configuration. That is, the main body portion, a slider portion slidably attached to form a measurement portion sandwiching the measurement site between the main body portion, and the slider portion approaching and separating from the slider portion, A finger hook slid in the same direction as the sliding direction of the slider section and urged by an elastic body in a direction away from the slider section; A detection unit that detects that the vehicle has approached a distance; and a measuring unit that reads a distance of the measurement unit at a timing detected by the detection unit and measures fat thickness based on the distance.

Preferably, the apparatus further comprises means for outputting an audio signal when detected by the detection unit.

Preferably, the main body, the slider, and the finger hook are formed of resin.

Preferably, the main body and the slider are formed such that a portion forming the measuring portion is lightened.

Preferably, the main body is provided with a holding portion formed in a waveform.

[0012] Preferably, a switch is provided in the main body, wherein a switch is provided in a crater-shaped recess provided in the main body.
The switch top is provided to be lower than the surface of the main body.

Preferably, a through hole is provided in the main body.

Preferably, the slider section is urged by an elastic body in a direction in which the measurement section closes.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION

<Configuration of Digital Body Fat Meter> FIG. 1 is a perspective view of a fat meter body according to the present invention. The measurer grasps the main body 100 and slides the slider 9 that slides along the guide groove 11 in the longitudinal direction of the main body together with the lever switch 9b while holding down the lever switch 9b with a thumb or the like. And
The measurement site is sandwiched between two claws constituting the measurement unit, namely, the fixed measurement claw 2 fixed to the main body side and the slide measurement claw 9a which is a part of the slider 9, and the thickness is measured. A predetermined process is performed on the measurement result, and the measurement result and the processing result for the measurement result are displayed on the display unit 1. Also,
Some settings associated with the measurement are performed by operating switches 4 to 8 provided on the main body. In this device, many parts such as body switch, lever switch and slider are made of polyether such as polyphenylene oxide, polyester such as polyethylene terephthalate and polybutylene terephthalate, acrylic resin such as polyacetal and polymethyl metaphthalate, and ABS resin. , Styrene resins such as high impact styrene,
It is formed of a synthetic resin that can be made opaque or opaque by coloring, such as a polyolein resin such as polypropylene or a polycarbonate resin.

FIG. 2 is a three-sided view of the fat scale of FIG. In the figure, (a) is a front view of the main body, (b) is a bottom view, (c)
Is a side view, and (d) is an AA cross-sectional view. Main unit 100
, The holding portion 22 is formed in a waveform so that the measurer can easily hold it. Further, a holder hole 10 for holding through a string or the like is also formed. A display unit 1 is provided on the front of the main body. As will be described later, the measurement conditions set by the switches 5 to 8, the measured body fat thickness, the body fat percentage, and their differences from the standard values are displayed there. Will be displayed. As the switches, in addition to the power switch 4, as a setting input unit, a gender setting switch 8 for setting gender of the subject as a measurement condition, an age increasing switch 6 for setting an age, an age decreasing switch 7. (Both are collectively called an age setting switch), and a decision switch 5 for confirming the set gender and age.

These switches have a top portion which is
The height of the main body 10
The button is not pushed if the operator does not leave the button 0 or if the operator simply squeezes it, and the button is not pushed unless the user presses the button consciously. Since the depression for storing the button has a crater shape, the depression gradually expands from the base of the switch to the vicinity of the top, so that the switch can be easily pressed.

The lever switch 9b functions as a switch for applying a trigger for measurement.

The lever switch 9b is used during measurement by a measurer putting his finger on the slider 9 and pulling the slider 9 to first open the measuring section, and then press the slider to apply a predetermined pressure to the measurement site. Therefore, in order to facilitate such an operation with one thumb, a finger hook portion provided with a chevron-shaped non-slip rib is provided.

The battery cover 3 is a cover for storing a button type battery.

As can be seen from FIG. 2B, the main body 100 is formed by joining the front member 20 and the back member 21 together.
A slider 9, a display unit or a control circuit is provided therein. FIG. 2D shows an AA cross section of FIG. 2A. The slider 9 is incorporated so as to sandwich the guide rails 21a and 21b formed integrally with the main body back side member 21, and slides along the guide rails 21a and 21b. On the side of the front side member 20 of the main body 100, a control board 12 provided with a control circuit is accommodated. A linear encoder of a capacitance type is attached to the slider 9 and the control board 12. The linear encoder has a slider section 9
When the sensor attached to the sensor is detected by the sensor, a detection signal is output. The detection signal is counted, and the amount of movement of the slider is detected. From this amount of movement, the fat thickness sandwiched between the measuring claws 2 and 9a is obtained.

The capacitance type linear encoder used here is a small, lightweight and inexpensive device, and has low power consumption. In addition, both the accuracy and the resolution have sufficient performance for measuring fat thickness.

FIG. 3A is a view of the main body 100 seen through the slider 9 and the guide rail 21 from the back side member 21 side. The measurement claws 2 and 9a are provided with hollow portions 2-1 and 9a-1, respectively, which are lightened for the purpose of weight reduction and high rigidity. Also, lever switch 9b
A hollow portion 9h is provided for the same purpose. In addition,
From the viewpoint of appearance, the lightening portions of the measuring claws 2 and 9a may be covered with the covering portions so that they are not visible.

The slider 9 has a hook 9g formed integrally with the slider 9 and a hook 21c formed integrally with the back member 21 of the main body 100. By the spring 9f which is an elastic body,
It is urged in the direction of arrow B. The sliding direction of the slider 9 is restricted only in the longitudinal direction of the main body by the guide rails 21a and 21b. Therefore, at the time of non-measurement, the measuring claw 9a
And the measurement claw 2 is in contact with each other, that is, in a state where the measurement section is closed. FIG. 3B is a partial sectional view from the lower surface of the main body. An electrical module 31 including a linear encoder, switches, and a display unit 1 is provided on the control board 12. The block configuration of these electrical modules will be described later. <Structure of Constant Pressure Mechanism> FIG. The slider section 9 is provided with a constant pressure mechanism for maintaining a pressure held between the measurement claw 2 and the slider 9 during measurement at a predetermined value.

The lever switch 9b is separate from the slider 9. The round bar-shaped projection 9e of the slider 9 is inserted into the hole 9h of the lever switch 9b, and the lever switch 9b slides along the projection 9e. A compression spring A, which is an elastic body serving as a second urging member, is inserted into the hole 9h, and is compressed by the end of the projection 9e and the bottom of the hole 9h. However, the lever switch 9b is restricted by the stopper 9j, and the lever switch 9b urged by the spring A comes into contact with the stopper 9j at a predetermined pressure and does not move any further. Therefore, when the slider 9 moves freely, the lever switch 9b also moves together with the slider. However, with the slider 9 fixed, the lever switch is pushed in the direction of the measuring claw 9a, and the force is
When a predetermined value determined according to the spring constant is reached, the spring A is compressed and the lever switch 9b moves until it comes into contact with the slider 9. The lever switch 9b is
A plate-like guide portion 9k provided on the slider 9 is sandwiched therebetween, thereby preventing rotation around the protrusion 9e.

The lever switch 9b has a protrusion 9
i is provided. Since the lever switch 9b is normally urged by the spring A so as not to press the switch 9d, the measurement switch 9d is in an off state when no measurement is performed. However, when the lever switch 9b is pressed against the slider 9, the protrusion 9i pushes the measurement switch 9d provided opposite to the switch 9d.
Is turned on.

When the measuring switch 9d is turned on, a trigger is used to take in a measured value from the linear encoder. The spring constant of the spring A is determined so that the pressure (measurement pressure) when the measurement switch 9d is turned on is 10 g / sq mm, which is the best. FIG. 5 is a block diagram of the present digital subcutaneous fat meter. The sensor unit 505 is a capacitance-type linear encoder, and outputs a detection signal according to the amount of movement when the slider 9 slides. The accuracy of the encoder is such that subcutaneous fat thickness can be measured in 1 mm units. The detection signal is counted by the counter 502a, and the counter value is read by the CPU 501 at the timing when the measurement switch 9d is turned on, and the counter 502a
Is converted into the movement amount of the slider 9 from the reset state. Since the capacitance encoder indicates the displacement of the slider 9, it is necessary to reset the counter 502a with the measuring unit closed. Since the slider 9 is urged against the measurement claw 2 by the spring 9f, the measurement claw 9a and the measurement claw 2 are in close contact with each other during non-measurement, and the measurement section is closed. Therefore, if the counter 502a is reset when the power is turned on, it can be expected that the counter is reset with the measuring unit closed.

The CPU 501 executes a control program or the like stored in the ROM to calculate the position of the slider 9 and also, based on the gender and age set from the switch group 503, the difference from the standard and the body fat percentage. It calculates and controls the entire system.

Various values calculated by the CPU 501 are as follows:
The image is displayed on a digital display 504 such as a liquid crystal display. These values can also be transferred to a host computer (not shown) via a data output unit 506 such as a serial I / O interface. The host computer receiving the data via the interface can store the measured values and display them, for example as a graph, to visualize the trend.

The set gender and age, the measured fat thickness, the calculated body fat percentage, and the like are stored in the RA of the CPU 501.
M. This RAM is backed up by a battery, and data remains even when the power is turned off.

Under the control of the CPU 501, the buzzer 507 sounds appropriately to call attention of the measurer. <Setting and Measurement Control Procedure> FIG. 6 is a state transition diagram showing a mode in which the digital body fat meter operates. FIG.
8 and 9 show a display example in each mode and an operation example by operating each switch. This digital subcutaneous fat meter
When the power is turned off, the apparatus is in the off mode 601. When the power switch 4 is pressed, the counter 502a is reset, and the mode transits to the gender setting mode 603.

(Gender setting mode) Gender setting mode 603
In, the last determined gender is displayed blinking, and when the gender switch 8 is pressed, the set values “male” and “female” are set.
Are alternately switched (process 603a), and the switched gender is displayed blinking (see the gender setting mode display field 701 in FIG. 7). When the confirmation switch 5 is pressed in a state in which either the gender of the subject or the gender is blinking,
The gender blinking at that time is determined, and the process proceeds to the age setting mode 604.

(Age setting mode) Age setting mode 604
When entering, first, the last determined age blinks (see FIG. 7, display field 702 of age setting mode), and “△”
When the switch 6 is pressed, the age currently displayed is set to one.
When the “▽” switch 7 is pressed, one is subtracted from the age. In addition, when these buttons are pressed continuously for more than one second, the age is continuously added or subtracted. When the age of the person to be measured is set and the confirmation switch 5 is pressed in a state where the age is blinking, the age displayed at that time is decided, and the mode shifts to the measurement mode 605.

In the setting flow, the age setting mode may be performed before the gender setting mode.

(Measurement Mode) In the measurement mode 605, until the measurement switch 9f is pressed, the gender and age set and determined so far are displayed, and
“00” is displayed as the measured fat thickness (FIG. 8,
Display column of measurement mode (a)).

In this state, the measurer slides the slider 9 to open the measurement claws 2 and 9a, grasps the fat layer of the measurement site such as the flank, and then sandwiches the measurement layer with the measurement claws 2 and 9a to strongly pinch the measurement site. Press the lever switch 9b (step 605a in FIG. 6). As described above, the linear encoder and the CPU 502 determine the amount of movement of the slider 9 from the point where the counter 502b is reset, that is, the body fat thickness from the value of the counter 502b. When a predetermined pressure is applied from the lever switch 9b to the slider 9 by the action of the spring A, the measurement switch 9d is turned on.

When the measurement switch 9b is turned on, the CPU 502 reads the value of the counter 502a at that time, and measures the position of the slider 9, that is, the body fat thickness at the measurement site based on the value. At the same time, a buzzer 507 for outputting sound as a leaving means is sounded to inform the measurer that the measurement is completed. Then, the body fat percentage, the body fat thickness based on the standard, and the obesity degree are also calculated, and these values are displayed (procedure 605b in FIG. 6). The processing procedure at this time is as follows. a: The measured value (the value of the counter 502a) is fetched. b: Calculate the body fat percentage. c: Determining the degree of obesity. d: The body fat thickness (FIG. 8, display column (b) 703 in measurement mode) converted from the measured value and the body fat percentage obtained in step b (FIG. 8, display column (b) 704 in measurement mode) Display for 2 seconds. e: Calculate fat thickness from standard. f: The fat thickness based on the standard obtained in step e is displayed for 2 seconds (FIG. 8, display column (c) 706 in measurement mode). g: Thereafter, the display of the calculated body fat thickness and body fat percentage,
The indication of fat thickness from the standard is alternately performed, and the measurement is repeated until the measurement is performed again or the power is turned off.

The obesity degree determined in step c is shown in FIG.
Are continuously displayed as an obesity degree display bar 705 in display columns (b) and (c). The obesity degree is determined in a plurality of stages (four stages in the present embodiment), and a display bar corresponding to each stage is turned on. As shown in FIG. 2A, on the main body side below the display unit, the obesity degree is written, for example, as "overweight", "standard", "overweight", "overweight", etc. corresponding to each display bar. Thus, the user can determine the obesity degree by looking at it.

In alternately displaying the fat thickness and the body fat percentage and the fat thickness from the standard, a display indicator 70 is provided to indicate what is currently displayed.
7 or 708 is displayed according to the display content. This indicator is, for example, a dot or an arrow.
"Fat thickness" written on the right side of the display panel as shown in (a)
It corresponds to the display "from standard".

FIG. 10 shows a display example including the display unit 1 and items displayed around the display unit 1 by printing or the like. In this case, the subject is a 20-year-old woman, which is set as such in the gender and age setting modes. When the measurement is performed here, as shown in FIG. 10B, the degree of obesity (here, “thickness”), the measured body fat thickness (18 mm), and the measured body fat percentage (26.0%) are obtained. The indicator 707 indicates that the displayed content at that time is “fat thickness”.
Indicated by After this display is done for 2 seconds,
Similarly, a fat thickness (+6 mm) above the standard as shown in FIG. 2A and the fact that the displayed content is a fat thickness above the standard are similarly shown.

Here, the arithmetic expressions in the above-mentioned steps b, c and e are as follows. Body fat percentage T (step b) [Female] T = 4.570 / {1.071- (0.00101 * S)-(0.00029 * N)}-4.142 [Male] T = 4.570 / {1.09055- (0.0012 * S)-(0.00026) * N)}-4.142 where S is the measured fat thickness, N is the set age,
T is the body fat percentage. T is obtained as a value obtained by rounding the fourth decimal place. That is, the body fat percentage is calculated using the measured fat thickness and the age and gender of the subject as parameters. Note that the calculated body fat percentage is displayed as a percentage. Obesity Degree Determination (Step c) The following determination is made according to gender and body fat percentage.

Gender Body fat percentage Judgment ----------------------------------- Female --- 0.000-0.200… Yasegi 0.201-0. 250… Standard 0.251-0.300… Overweight 0.301 or more… Overweight ------------------------------------------------ Male 0.000- 0.100… thin skin 0.101-0.150… standard 0.151-0.200… fat fat 0.201 or more… too fat That is, the degree of obesity is calculated by the calculated body fat percentage and the subject's It is determined based on gender. Fat thickness P from standard (step e) Calculated by the following formula according to gender.

P = SQ where [female] Q = {1.071-0.00029N-4.57 / (R + 4.142)} / 0.00101 [male] Q = {1.09055-0.00026N-4.57 / (R + 4.142) } /0.0012. In the above equation, P is fat thickness than standard, S is fat thickness, Q is standard fat thickness, and N is age. R is the boundary fat percentage with respect to the standard obesity level, and as described in the above-mentioned section on obesity level determination, in women, the lean boundary fat percentage is 0.20
1, the obesity-type boundary fat rate is 0.250, and in men, the lean-type boundary fat rate is 0.101, and the obesity-type boundary fat rate is 0.150.
It is. The fat thickness P above the standard is 0 when the obesity degree is normal, the obesity-type boundary fat percentage is used as the boundary fat percentage when the obesity degree is higher than the standard, and the boundary fat percentage is used when the obesity degree is lower than the standard. Is calculated using the lean boundary fat percentage. The value of P is displayed with a plus sign for an obese type and a minus sign for a lean type. In addition,
If the determined degree of obesity is “overweight”, a “+” sign may be used, and if “overweight”, a “++” sign may be used. That is, the fat thickness from the standard is calculated as the difference between the measured fat thickness and the standard fat thickness determined from the age and gender of the subject.

The above is the operation mode during the normal measurement.
A test mode described below is also provided.

(Test Mode) The test mode is entered by simultaneously pressing the three switches "▽", "△" and "power" from the off state. The test mode is a mode for testing the display and each switch.

When the test mode is entered, first, all the segments of the display section 1 are turned on (see FIG. 7, test mode display column). After that, an operation corresponding to the pressed switch is performed.

First, when the power switch is pressed, the normal mode where the power is turned off is changed to the gender setting mode in the test mode. When the gender setting switch is pressed, 1 is turned on for all of the number segments used for displaying the age, the body fat percentage, and the body fat thickness. Similarly,
When the confirmation switch is pressed, 4 is added to all the number segments,
When the “▽” switch is pressed, 2 is applied to all the numeric segments.
When the "△" switch is pressed, 3 is displayed on all the numeric segments, and when the measurement switch is pressed, 5 is displayed on all the numeric segments (see the test mode column in FIG. 7). As described above, the switches and the display panel, and the display contents corresponding thereto are determined in advance and the display is performed according to the operation, so that it is possible to test that the switches and the display panel and their control are correctly performed.

The above is an operation example in each mode. In addition, the following exception control is also performed. Error display: When an inappropriate operation is performed, such as when the measurement switch is continuously pressed, an error is displayed (Er
Wait for release by power switch or confirmation switch. Battery low display: Regardless of the mode, when the voltage supplied from the battery falls below a predetermined value, the battery warning light is turned on (FIG. 8, segment 709 in the battery low display column). This display is turned off when the battery voltage becomes higher than the predetermined value again. Auto-off: The power is turned off after a lapse of a predetermined time, for example, 5 minutes, after the last time any switch is pressed. Thereby, useless consumption of the battery can be prevented.

After replacement of the battery, the retained R
Since the contents of the AM are lost, the age and gender before the power is turned off cannot be displayed in each setting mode.
Therefore, in this case, the setting method changes as shown in FIG.

First, when entering the gender setting mode from the power-off mode, the segments "male" and "female" indicating the gender are simultaneously blinked, and "25" is lit as the age. Here, when the gender setting switch is pressed, "female" is displayed first.
Subsequent steps are the same as in the normal case.

The age setting mode is the same as the normal case except that the initial value of the age is set to 25.

With the configuration and procedure as described above,
By using the digital body fat meter according to the present embodiment, the subject can easily measure the body fat percentage by himself. Specifically, it has the following features. (1) Because a capacitance-type linear encoder was used for measuring fat thickness, the entire device could be made compact, lightweight and inexpensive. Further, the capacitance type linear encoder has low power consumption and can be used for a long time even with a small capacity battery. In addition, since a small battery can be used, this also contributes to downsizing of the main body. (2) The measuring section is urged to be always closed by the spring. Since the counter value of the encoder at the time when the power is turned on is reset, if the power is turned on while measurement is not being performed, the fat thickness from that state can be measured correctly. Therefore, there is no need to use an expensive and large absolute encoder, and the device can be manufactured at low cost. In addition, since the measurement unit is always urged to close, operation with one hand can be easily performed. (3) Since the measurement switch is provided with a constant pressure mechanism, the reproducibility of the measured value is good even when measuring a soft tissue such as fat. The constant pressure mechanism of the present apparatus is related not only to the spring A pressing the lever switch, but also to the pulling force of the spring 9f which urges the entire slider to close the measuring section. Although the tensile force of the spring 9f changes according to the amount of elongation, the spring coefficient of the spring 9f is sufficiently smaller than the spring coefficient of the spring A, so that the influence on the measured value can be almost ignored. (4) When the measurement is completed, the buzzer notifies the measurer of the completion, so that the measurement completion can be reliably notified to the measurer. (5) Most parts of the device, such as the main body, slider, lever switch, and guide rail, are made of resin, and the measuring claw and lever switch are lightened for weight reduction and rigidity. As described above, the light weight allows the subject to measure by himself, and a sufficient rigidity is ensured, so that the error of the measured value due to the bending of the measuring claw is small. Also, since the part that contacts the skin is resin,
It does not have the coldness of metal and does not cause discomfort. (6) It is formed according to the shape of the hand when the body is gripped. The lever switch is also provided with a finger hook that is easy to operate with one thumb, so that it is easy to handle with one hand and measurement by one person is easy. (7) Be careful not to accidentally press the switches when holding the main unit or placing it on a flat surface such as a desk.
In a crater-shaped depression provided in the main body, the switch top is provided so as to sink below the surface of the main body.
In addition, since the depression has a crater shape, operation with a fingertip is easy. (8) Since a hole is provided at one end of the main body to allow the strap to pass through, if the strap is inserted through the hole, it will not be damaged even if it is accidentally dropped. (9) Since an output port for sending measurement results and calculation results to the host computer is provided, data management such as creation of a trend graph can be performed by the host computer. (10) Since the body fat percentage is displayed in four grades “Yasagimi”, “Standard”, “Thickness” and “Overweight” according to gender and age, it is easy for the operator to understand and objective judgment can be made. (11) Since the difference between the measured body fat thickness and the standard is displayed, it is easy to understand the specific fat thickness, and the thickness of the subcutaneous fat can be accurately managed as a numerical value. For this reason,
It is easy to manage as a specific target when performing weight loss or weight increase. (12) Since only gender and age are input as attributes of the subject, the measurement procedure is very simple. (13) Since the measurement results such as fat thickness and body fat percentage and the difference from the standard value are alternately displayed in a time-sharing manner, both data can be displayed in a sufficiently easy-to-read size with a small number of segments. Therefore, the size of the liquid crystal can be reduced, and an inexpensive configuration can be realized.

[0053]

As described above, according to the present invention, it is possible to provide a subcutaneous fat meter which can obtain a stable measured value, is lightweight, and can be easily measured by the subject alone.
