The present invention relates to controlling an electrode moving device to maintain a fixed posture to measure an accurate human body impedance in a correct posture.

In general, a body composition measuring device is configured to measure and analyze an impedance measured differently according to parts of a human body by flowing a microcurrent to a human body, and various types of measuring devices have been developed.

An example of a conventional body composition analyzer will be described with reference to FIGS. 1 to 3.

The body composition measuring device 1 is formed in a substantially L-shaped shape, and a weight scale 2 is installed at the bottom. The scale 2 includes a footrest 2a for measuring the weight of the subject, and the footrest 2a and the electrode handles 8a and 8b have electrode portions 10 and 22 in contact with both hands. Install it.

The electrode part is a palm electrode (10a), (10b), (10b, 10d, 22c, 22d) and the electrode handles (8a, 8b) formed on the footrest (2a) 22a) and 22b.

The sole electrode is composed of electrodes 10c and 10d for flowing a current, and electrodes 22c and 22d for measuring a voltage, and electrodes 10a and 10b for passing a current to the palm electrode. It consists of electrodes 22a and 22b for measuring overvoltage.

2 is a block diagram of the body composition measuring device 1, in which eight electrodes 10a, 10b, 10c, 10d, 22a, 22b, 22c and 22d are in contact with the left and right limbs. Connected to (19).

The electrode exchange device 10 is connected to the control device 13 via the current supply device 11 and the voltage measuring device 12.

This control apparatus 13 is equipped with the microcomputer, and has the memory | storage device 14 which stores various data.

In addition, the display-use screen 7 shown in FIG. 1 is provided with an input device 15 and a display device 16 therein in an electrical circuit, and a control device via an input / output control device 17 for controlling them. It is connected with (13).

Meanwhile, the weight measured by the scale 2 is configured to be connected to the input / output controller 17 and the controller 13.

Reference numeral 18 denotes a power source for supplying power to the control device 13 or other device.

The body composition measuring device configured as described above is initialized when the power source 18 of the measuring device is turned on, and the mode is measured so that the weight of the subject can be measured.

Using the input device 15, the subject can input his / her weight or directly measure the weight with the scale 2 of the measuring device and store the weight in the storage device 14.

When the weight is measured or input, the personal information of the subject, ie, gender, age, age, height, and the like, is sequentially input to the input device 15 according to the guidance display of the display device 16 in the next step. Store that data in.

Subsequently, the electrode exchange device 19 is driven in a mode that guides the measurement object through the display device 16 so as to be in contact with the electrode and can measure the human body impedance of each part of the body.

The electrode exchange device 19 controls the on / off of the palm electrode and the sole electrode to measure the impedance of the body part of the subject.

1, the subject goes up to the measuring instrument of FIG. 1 to cover the electrode handles 8a and 8b with both hands so that the palm electrodes 10a, 22a, 10b and 22b are in contact with each other, and the feet are attached to the sole electrode 10c. When it comes into contact with (10d), (22c) and (22d), the human body impedance of the subject is measured.

For example, the circuit is controlled so that current flows through the sole electrode 10c and the palm electrode 10a of FIG. 3, and the voltage is measured through the sole electrode 22c and the palm electrode 22a. The impedance to the body can be measured.

On the contrary, if the circuit is controlled so that the current flows through the sole electrode 10d and the palm electrode 10b and the voltage is measured through the sole electrode 22d and the palm electrode 22b, the impedance of the right part of the subject is measured. You can measure it.

In addition, if the circuit is controlled so that current flows through the sole electrode 10c and the sole electrode 10d, and the voltage is measured through the sole electrode 22c and the sole electrode 22d, the impedance of the lower body of the subject can be measured. Can be.                         

In the same way, the circuit is controlled so that a current flows through the palm electrode 10a and the palm electrode 10b, and the voltage is measured through the palm electrode 22a and the palm electrode 22b. Can be measured.

In addition, by connecting the two palm electrodes and both the sole electrode in the same manner at the same time to measure the voltage through the current through the entire human body can measure the impedance of the entire human body.

Of course, it is possible to measure the impedance of the human body diagonal through the electrodes of one palm and one sole, the other palm and the other sole.

As described above, the body value (body fat, muscle mass, etc.) of the subject is measured by combining or calculating the impedance value of each body part and the information of the subject already input to the memory device 14.

The body composition measuring device configured as described above is configured such that the sole electrodes 10c, 10d, 22c, and 22d, which are formed on the flat footrest 2a of the scale, are exposed and fixed on the footboard surface. The front and rear soles of the meter are in contact with each electrode.

In the structure in which the electrode is configured as described above, as shown in FIG. 4A, a factor causing an error in human body impedance measurement occurs according to the measurement posture of the subject. In other words, the posture to be measured is changed according to the user's physical condition. These postures are separated from the correct posture and thus increase the measurement error.

In addition, in order to measure accurate human impedance, it is inconvenient and laborious because the arm must be kept at least 1 minute by opening the arm approximately 30% during measurement as shown in FIG. 4B. Moreover, in order to make such accurate measurement, there is a disadvantage that accurate measurement is possible only with the help of an expert when measuring body composition.

The present invention has been made to solve the above problems, in order to accurately induce the measurement posture of the subject when measuring the human body impedance of the subject, so that both arms of the subject to be in contact with the front to be in contact with the electrode The electrode is configured to move forward by the arm length when the subject extends the arm forward. Since the posture may be distorted according to the height of the person to be measured, the electrode moves according to the height of the person to be measured, so that the body is configured to induce a correct posture when measuring impedance.

Accordingly, an object of the present invention is to provide a structure of a moving electrode that can reduce the measurement error, and to provide a body composition measuring instrument that can accurately measure the human body impedance by reducing the measurement error.

Hereinafter, the technical configuration and measuring method of the body composition analyzer of the present invention will be described in detail with reference to FIGS.

Is done. The above-described devices are configured so that the measurer can read the measured values well. This technique is similar to the prior art.

The impedance measuring unit includes an electrode exchanger, a current supply device, a voltage measuring device, two pairs of sole electrodes in which the feet of the subject are in contact with the foot of the scale, and the soles of the subject instead of the soles of the subject. The pair of ankle electrodes 102b in contact with each other, and two pairs of palm electrodes 210 in which both hands of the subject are in contact with each other, and the pair of palm electrodes are configured to be wrapped by hands, respectively. Are arranged in pairs.

On the other hand, with respect to the footrest of the scale 102, the electrode handle 210 is controlled to be movable up, down, forward and backward by an electrode movement means constituted by a solenoid, for example.

In the present embodiment, the electrode moving means is installed to be movable up and down with respect to the pillar 100 and the pillar 100 which is rotatably set with respect to the scale 102 in order to move the electrode handle 210. It may be configured as a rod 100 for fixing and supporting 210. In this way, the arm of the subject is placed side by side to provide stable measurement conditions.

6A is a side view of the measuring device in a state in which the pillar 100 is rotated at an angle to increase the length and the front and rear lengths of the measuring device in the basic state.

6B shows a state in which the rod 101 is raised and a state in which the pillar 100 is rotated in the state.

The application of this operating state is illustrated in FIGS. 7A and 7B, where FIG. 7A is taken at the original position when the average person is measuring, and FIG. 7B is a rod (when measured by a tall and bulky person). In addition to increasing the length of 101, the pillar 100 is also rotated at an angle to show a state in which an accurate measurement posture is provided.

Since the impedance measuring method between the electrodes can use the mechanism of FIG. 3 mentioned in the prior art, repeated description is omitted.

The body composition measuring method of the present invention will be described in detail with reference to FIG. 8.

The body composition analyzer of the present invention is set to the weight measuring mode in which the device is in an initial state when the power is turned on, and the weight is measured when the subject is placed on the display unit on the footrest 102a of the scale (S1).

The controller detects fine movements on the scale of the scale and the deviation of the subject to determine whether normal weight measurement is performed (S2). When it is determined that normal weight measurement is performed, the controller stores the measured weight data in a memory device and displays the display device. Output through (S3). If it is determined that the normal weight measurement is not made, the controller moves back to the initial weight measurement mode.

When the weight measurement is finished, the user is guided through the display device 200 such as a speaker or a screen to input personal information of the subject, and the subject enters personal information such as gender, age, height, etc. according to the guidance. Input by using (S4).

When the personal information is input, the control unit determines whether the personal information is correctly input (S5), and simultaneously determines whether the change in the weight of the subject is in the error range in the process of inputting the personal information (S6).

If the personal information is correctly input and it is determined that the change in the weight of the subject is in the error range, the electrode moving means is adjusted to the front of the arm to measure the body impedance in a stable state.

When the height of the subject is large or small, the electrode moving means may be moved up and down as in the examples shown in FIGS. 6 and 7 to adjust it to its height and set it.

Subsequently, if the weight of the subject is within the error range during the personal information input process and there is an error in the input of the personal information, the controller moves to step S4 to control the personal information to be modified and input the personal information. If the information is correctly input, but the change in the weight of the subject falls outside the error range, it is determined that the subject has moved away from the scaffold 102 and moves to step S1.

On the other hand, in step (S7) and guided through the display device 200 so that the body of the subject to be precisely in contact with the sole electrode and the palm electrode position (S8), the subject is wrapped around the electrode handle 210, the control device Determining whether each electrode has a poor contact from the body of the subject (S9).

If there is no contact failure of each electrode, the measured impedance is measured (S10).

The impedance measurement is performed by supplying a current to the palm electrode and the sole electrode or the ankle electrode selected by the electrode exchanger through a current supply device, and calculating the voltage of the electrode section by a voltage measuring device.

In the process of measuring the impedance, the control device determines whether a contact failure or separation of the electrode occurs during the impedance measurement (S11). If there is no detachment or poor contact of the electrode, the controller calculates the measured impedance data by combining the measured impedance data with the personal information of the subject, and the body mass, body fat, body fat percentage, obesity, body mass index, and basic metabolic rate of the subject. Etc. are calculated, and the result is stored in the storage device and output through the display device 200 (S12).

If separation of the electrode or contact failure occurs in step S11, the process moves to step S7 to allow the impedance to be measured again.

Subsequently, after the impedance measurement is finished, when the subject descends on the scale of the scale, the meter tilted in all directions is turned off and automatically moves backward to return to the initial state as shown in FIG. 7B.

If you hold the mobile electrode device according to the present invention, the arm does not hurt so that the impedance can be measured in a comfortable posture, regardless of the height of the person to measure the human body impedance by measuring the human body side by side in front of the tall or large people By inducing, it is possible to measure the correct impedance according to the correct posture.
