As shown in the figure, an internal detailed circuit portion 21, an ADC detailed circuit portion 431, and a detailed circuit portion 451 of a control portion are shown in a power supply electrode.

As described above, the operation of each circuit section 11 in the measuring electrode for measuring the impedance of each body part in the impedance measuring apparatus 10 will be described in detail with reference to FIG. 7 below.

FIG. 7 is an enlarged view of each circuit part 11 of the measuring electrode for measuring the impedance of each body part in FIG.

As shown in FIG. 7, input terminals 121, 131, 141, and 151 having different impedances and receiving current through each predetermined body part of the left hand by 5V of the energizing electrode, and impedances The load values 112, 113, 114, and 115 corresponding to the impedance magnitudes of the respective body parts are connected to each other so that the impedances at the output terminals 182, 183, 184, and 185 are the same.

As an example, each of the input terminals includes an input terminal 121 through which a current is inputted through a left hand detection, an input terminal 131 through which a current is inputted through the left hand side and the left front side of the left hand palm, An input terminal 141 for inputting a current, and an input terminal 151 for inputting a current through the left-hand thumb.

In addition, each of the output terminals has an impedance output terminal 182 of the left hand detection, an impedance output terminal 183 of the left hand palm and a front left hand portion of the left hand palm, and an impedance output terminal 184, and an impedance output terminal 185 of the left hand thumb.

Each of the loads 112, 113, 114 and 115 is connected between the respective input terminals 121, 131, 141 and 151 and the respective output terminals 182, 183, 184 and 185 for voltage or current distribution. The magnitude of the impedance and the proportional value are connected. The impedance of each body part is measured in advance and the load value corresponding thereto is also stored in a memory unit (not shown) through experiments in advance.

As one example, since the impedance of the body part connected to the input terminal 141 is the largest, the resistance value 114 according to the impedance is the largest.

Hereinafter, the operation of the present invention will be described with reference to FIG.

As shown in FIG. 2 or FIG. 3, a predetermined voltage, for example, a direct current of 5 V is applied to a predetermined first body part of the subject, for example, a right hand finger and / or a right hand palm, And measuring an output impedance of a body part in a device in which a current flows through a measurement electrode contacting the predetermined second body part of the subject, e.g., the left hand finger and / or the palm,

The respective circuit portions of the measurement electrode 11 to measure the impedance for each predetermined body part as shown in FIG. 3 or 4 are configured to correspond to the respective body parts, and the respective circuit parts of the respective measurement electrodes have different load values 112, 113, 114, and 115, respectively.

On the other hand, the respective resistance values connected in parallel to the respective different load values are the same load value (1K).

 As shown in FIGS. 1, 3 and 4, a sensor unit 17 is connected to each measurement electrode to measure impedance of each body part, , Each current flowing through each of the body parts and each of the measuring electrodes of the body part flowing through the sensor part contacting each body part is measured by a predetermined circuit part (voltage / The output impedance of each of the body parts output from the output terminals 182, 183, 184, and 185 of the respective measurement electrodes becomes equal to each other.

Further, 5V is applied to each of the branches to be branched, and the currents flowing through 1K divided by different resistance values (112, 113, 114, 115) and 1K are equal in each circuit part. Therefore, the output impedance at each output terminal for each body part will be the same, and the state of the subject can be accurately diagnosed by using all of the same output impedance.

As shown in FIGS. 1, 6 and 7, the measuring electrodes connected to the energizing electrodes are connected to each other in series, and the measurement electrodes connected to the energizing electrodes measure each impedance The electrode circuit portions are connected in parallel with each other. (The respective circuit parts by the input stages 121, 131, 141 and 151 in Fig. 7 are connected to each other in parallel)

The magnitude of the load value connected to each circuit part of each measuring electrode 11 is proportional to the impedance magnitude of each body part.

When a current flows through a body part having a large impedance, a corresponding load value among the load values 112, 113, 114, and 115 for voltage or current distribution is increased in the corresponding circuit part, So that the output impedance is the same.

3, the order of magnitude of self-impedance of each body part of the present invention is the left hand palm front right side part 14, the left hand palm and left hand palm front left side part 13, 12, and a left thumb 15, which are pre-measured results. Therefore, a load value for distributing a voltage or a current corresponding to the self-impedance magnitude of each body part is set. That is, since the self-impedance of the right-hand side portion 14 of the left-hand palm is the largest, the resistance value 114 in the circuit portion connected to the input terminal 141 is the largest.

The measuring electrode is configured inside the mouse type shown in FIG. 1, and a plurality of sensor units 17 are arranged outside the mouse type to contact predetermined body parts of the subject. (121, 131, 141, 151) of the measuring electrodes of the electrodes (7, 7).
