The present invention relates to a body fat analyzer, and more particularly, in addition to the body fat measurement function of the subject, by taking light irradiated to a specific site such as the waist, abdomen, pelvis of the subject to obtain the contour information, using the waist circumference, abdominal circumference The present invention relates to a body fat measuring device having a body circumference measuring function for efficiently managing body fat and obesity of a subject by having a function of accurately measuring the pelvic circumference and the like.

In general, the body fat analyzer is a device that measures the components of the human body by measuring the electrical impedance of the human body. In such a body fat analyzer, a bioelectrical impedance analysis (BIA) method is used to measure the components of the human body. The bioelectrical impedance analysis method transmits a weak alternating current into the human body to measure the human body electrical impedance, and measures the body water content of the subject through the height and weight of the subject, and calculates biometric information such as body fat amount, inorganic mass, and muscle mass based on this. That's how.

As described above, the existing body fat analyzer for measuring components in the human body including body fat includes an electrode for making electrical connection by contacting the body of the subject, an impedance measuring unit, an input unit, a display unit, and a controller. Here, the electrode usually comprises a pair of power generating poles in contact with the sole and the heel of the subject, and a hand electrode in contact with both hands of the subject. In addition, the impedance measuring unit is an impedance measuring circuit that measures the bioimpedance of the subject is module inside the apparatus. The control unit controls the entire apparatus, and generates a measurement result by processing the bioimpedance measured by the impedance measuring unit, and is installed in the form of an IC chip inside the measuring apparatus.

Meanwhile, a method of diagnosing abdominal obesity is a method of measuring waist circumference and hip circumference by measuring a waist circumference and hip circumference to calculate waist circumference and hip circumference ratio (WHR, Waist-Hip Ratio), and comparing the result with a standard value distinguished by gender. This is commonly used.

However, in the case of measuring body circumference with a tape measure, the subject was uncomfortable to perform the measurement by the subject himself, and the measure was performed by various factors such as the level of the tape, the degree of pulling, or whether the subject inhales or exhales. Since the measurement results are different, there is a problem in that the accuracy of the measured abdominal obesity is inferior.

Therefore, the present inventors provide a technique for adding a function to accurately measure the waist circumference or hip circumference of the human body regardless of the external environment of the subject or the subject using optical technology to the body fat analyzer to more accurately determine the state of the subject. After the study, the present invention was completed.

Therefore, the present invention adds the body circumference measurement function to accurately and easily measure the circumference of a specific body part such as waist or pelvis to the body fat measurement function so that the body fat or obesity of the subject can be efficiently managed.

In addition, the body fat analyzer 100 according to the present invention, a control unit for analyzing the body composition from the body impedance measured by controlling the overall device, and together with the contour information of the subject 101 photographed by the imaging unit 40 90 is built in.

Here, the power generating electrode 60 used as the body fat measuring means is a part which is in contact with both feet of the subject 101, and consists of a current application electrode 61 and a voltage measurement electrode 62. The current applying electrode 61 is a terminal for applying current to the human body through the foot of the examinee 101. The voltage measuring electrode 62 is a terminal that connects a circuit of an impedance measuring unit modular therein to detect impedance flowing through the human body through the foot of the examinee 101.

The footrest 50 is provided to be seated on the ground so that the subject 101 can stand on it, and a pair of power generating poles 60 corresponding to both feet of the subject 101 is provided on the upper portion of the footrest 50. Is formed. The inside of the scaffold 50 may be used by installing a weight measuring means (not shown) for measuring the weight of the subject 101.

In this case, the body fat analyzer 100 may further include a handle 70 gripped by both hands of the examinee 101. Preferably, a hand electrode (not shown) having an electrode for applying a current and an electrode for measuring a voltage may be formed on the handle 70, similarly to the power generating electrode 60. When the hand electrode is provided as described above, the body impedance of each part of the human body can be measured. In addition, when the handle 70 is configured to manually adjust the height of the operation unit 20 to be described in detail later, the examinee 101 is the operation unit 20 in a state in which both hands grip the handle 70 It can also play a role in allowing the height of the variable to vary. Here, the position of the handle 70 is freely selectable without being restricted, and preferably, may be installed on the upper or side surface of the operation unit 20, or may be variously formed by connecting with a separate wire. To reveal.

The operation part 20, which is one of the circumference information measuring means, is preferably formed in the shape of a "U" shape like a horseshoe as shown in FIG. The operation unit 20 is preferably formed smoothly in a streamline, because the circumference of the human body forms a streamlined gentle curve. However, the operation unit 20 is not necessarily limited to the gentle curved form of the "U" shape, it is obvious that the angle can be formed as the "c" shape.

The operation unit 20 may have an inner wall 22 formed at a predetermined height on an inner surface facing the examinee 101. When the light of the light source unit 10 to be described later is irradiated beyond the range of the subject 101, the inner wall 22 serves to block the light from proceeding infinitely outside the device. Therefore, even without a separate dark room or a separate light progress blocking means, the user is not restricted by the place in using the body fat measuring device 100 having a circumference measurement function of the present invention, the configuration is simpler to carry And the installation is considerably easy, and the economic cost is saved.

At least one light source unit 10 is installed in the operation unit 20 so that light is irradiated onto the surface of the body circumference of the subject 101. Preferably, the light source unit 10 may be irradiated in the form of slit light having a linear shape. The light source for irradiating the slit light may use any light source capable of forming an outline on the surface of the human body. Preferably, it is preferable to employ a laser beam that is excellent in straightness and can form a clear outline on the surface of the subject 101. In this case, the light source unit 10 may further include a separate means for further sharpening the outline as necessary. The contour is temporarily or continuously formed on the surface of the subject 101 and photographed by the photographing unit 40 which will be described later. The contour thus captured is used to provide size or shape data of the body circumference of the subject 101.

More preferably, the light source unit 10 may be formed on the inner wall 22 of the operating unit 20. In this case, the light source unit 10 emits light to the surface of the subject 101 located inside the operating unit 20. Irradiation forms an outline. At this time, the light outside the range of the examinee 101 is absorbed or reflected by the inner wall 22 in the opposite direction so that the light does not flow out. The light source unit 10 may be formed on the surface of the inner wall 22 of the operating unit 20, but is not necessarily formed on the surface of the inner wall 22 of the operating unit 20, by a separate connecting member It is obvious that it may be connected.

Here, the light source unit 10 is implemented so that light is irradiated to the human body of the subject 101 in the horizontal direction. When the light is irradiated to the human body of the subject 101 in the horizontal direction, the light source unit 10 can measure the circumference information of the subject 101. In this case, the shape of a specific part of the human body can be used as useful information by measuring the degree of obesity of the abdomen. In this case, the light is preferably irradiated in the form of a slit.

The photographing unit 40 is provided with one or a plurality. Preferably, the photographing unit 40 adopts a Charged Coupled Device (CCD) camera. The CCD camera helps to obtain a clear picture quality by converting the photographed image into an electrical form and transmitting the same.

The photographing unit 40 is formed at a different height so as to be spaced apart from the light source unit 10 by a predetermined distance. When the photographing unit 40 is positioned on the same horizontal line as the light source unit 10, the contour of the surface of the subject 101 photographed by the photographing unit 40 appears in a straight line shape so that the circumference information of the subject 101 is measured. Can't get it. The photographing angle at which the photographing unit 40 photographs the contour of the surface of the subject 101 is not limited, but is appropriately set so that the surface shape of the subject 101 can be photographed without distortion. At this time, the distortion phenomenon may be solved through a correction operation in the controller 90 to be described later.

The controller 90 analyzes contour information of the examinee 101 photographed by the photographing unit 40. The controller 90 is embedded in the body fat analyzer 100 having an IC measurement function of the present invention in the form of an IC chip. The controller 90 generates a bioimpedance measurement result by analyzing a body component from a bioimpedance measured by an impedance measuring unit (not shown) modularized therein, and together with the subject photographed by the photographing unit 40 ( The contour circumference information of the human body is analyzed from the contour image of 101). At this time, the contour circumference information of the human body analyzed by the controller 90 may be the size of the contour circumference of the human body, or may be the contour circumference shape of the human body.

The transfer part 30 is formed at one side of the operation part 20. In this case, the examinee 101 measures the circumference of the pelvis or abdomen in a state of rising on the footrest 50. Even when only a specific portion is continuously measured, the height of measurement varies according to the height of the examinee 101. Therefore, the operation unit 20 should be configured to vary the height so that the light source unit 10 formed in the operation unit 20 to be irradiated appropriately the site to be measured by the subject 101. To this end, the transfer unit 30 is configured to be able to vary the height of the operating unit (20).

In this way, the transfer unit 30 for varying the height of the operating unit 20 may be applied to various known techniques to make the operating unit 20 vertically movable. For example, the transfer unit 30 may be configured by adjusting the height by a screw method, adjusting the height by a piston and a rod, adjusting the height by a pinion gear and a rack gear, and the like. In addition, the transfer unit 30 may be configured by selecting from a manual type operated by the user's muscle strength, a semi-automatic type operated by a motor or the like by a button operation, and an automatic type which automatically recognizes a measurement part of the subject by a sensor. Preferably, the transfer unit 30 may be configured to be semi-automatic or automatic.

According to a preferred embodiment of the present invention, the operation unit 20 is formed to surround at least a portion around the subject 101. The operation unit 20 is a body in which the light source unit 10 is installed, and wraps the circumference of the subject 101 so that the light irradiated to the light source unit 10 does not diffuse to the outside. In order for the slit range of light not to deviate from the range of the subject 101, the shape of the operation part 20 may be manufactured in a donut shape.

The body fat analyzer 100 having a measurement of body circumference may further include a display unit 80 and an operation button 81 for outputting a bioimpedance measurement result generated by the controller 90 or contour circumference information of the human body. Can be.

According to a more preferred embodiment of the present invention, as shown in Figure 1, the operating portion 20 may be formed with an opening on at least one side. The opening is formed within a range in which the light of the light source unit 10, which is outside the range of the subject 101, does not infinitely travel outside the device. The opening is a passage through which the examinee 101 enters and leaves the examinee 101 so that the examinee 101 can be easily positioned inside the operation unit 20.

In addition, according to another preferred embodiment of the present invention, as shown in Figure 2, the operation unit 20 may be provided with a door 29 for opening and closing the opening. The door 29 may be fastened to the operating part 20 by a connecting means such as a hinge, but the door 29 may be used to open and close any of the openings formed in the operating part 20. Can be. As such, when the door 29 is provided in the operation unit 20, the operation unit 20 takes an integral continuous ring shape, thereby preventing light from leaking to the outside by the opening.

At this time, the transfer unit 30 may be provided with a drive motor (not shown) so that the height of the operation unit 20 by the drive motor is variable. In this case, as described above, the transfer unit 30 may be operated semi-automatically or automatically.

If provided by the person skilled in the art corresponding to the present invention implemented embodiment so that the transfer unit 30 can be changed to semi-automatic or automatic as follows.

As shown in FIG. 3, the transfer part 30 includes a fixed member 32, a transfer member 31 inserted into the fixing member 32 to move vertically up and down, and one surface of the transfer member 31. The rack gear 37 is formed, and the pinion gear 36 is meshed with the rack gear 37 and coupled to the drive shaft 35 of the drive motor. The fixing member 32 is fixed to one side of the footrest 50 seated on the ground. The transfer member 31 linearly moves up and down by the rotation of the drive motor. The drive motor is provided with an encoder to control the amount of rotation and the speed of rotation, and transmits the rotation pulse signal of the drive motor to the control unit 90 to utilize the information, such as height, elongation of a specific portion of the subject 101. do.

Meanwhile, the transfer unit 30 may further include a sensor to automatically set the measurement height based on the height of the person's navel. For example, when the transfer unit 30 is automatically configured, a sensor detects a position of a specific part such as the navel of the examinee 101 so that the transfer unit 30 moves the operation unit 20 by an appropriate height. can do. At this time, the sensor may calculate the transport distance of the transfer unit 30 to obtain the height of the navel of the examinee (101). In addition, the height of the subject 101 may be measured using the belly height information measured by the sensor. That is, the height of the navel calculated by the sensor as described above may be converted into the height of the examinee 101. This is because, in general, men and women and various ages, the position of the navel is formed very close to the height of 0.62 ~ 0.63.

As such, when the sensor is provided in the transfer unit 30, the height of the operation unit 20 is automatically changed to the height of the navel and the height of the navel is converted into the height to obtain the height information of the subject. It does not need to be installed, and the test subject or the measurer does not need to input height information separately, thereby providing convenience of measurement.

According to another embodiment of the present invention, the light source unit 10 may be provided to face the light to irradiate the front, rear, left and right of the subject 101. Since the front and the back of the human body are asymmetrical as described above, the light source 10 is positioned before and after the subject, respectively, to form an outline by irradiating light, and then synthesize the image photographed by each of the photographing units 40. The entire circumference of the subject 101 can be completed. Therefore, in this case, the entire circumference of the subject 101 can be efficiently scanned as compared with the case where the light source unit 10 is formed as a single unit, and thus the accuracy can be increased. The cost can be reduced.

On the other hand, the light source unit 10 is formed so as to be positioned on the side of the subject and the symmetrical circumference image of one of the left or right side of the subject photographed by the photographing unit 40 by using a relatively symmetrical point of the human body It is also possible to work in such a way that it is synthesized.
