Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The invention relates to the pathophysiology of various organs in the human body, and the change in the impedance value due to the abnormal autonomic nerve function of various organs is examined by measuring the impedance using meridian acupuncture points. The present invention relates to a meridian impedance measuring device.

2. Description of the Related Art When acupuncture points (pots) on human skin are given appropriate stimuli such as heat, pressure, electric potential, and lines of magnetic force, they act on the internal organs of various organs via meridians, and the immune function, biological defense function, and autonomy of the body. The homeostatic function of the nervous system is activated and abnormal biological functions are normalized. In the autonomic nervous system, when the sympathetic nervous system and the parasympathetic nervous system maintain an equilibrium state, the organ that holds the nerve is said to be in a normal (normal) state. But,
When the sympathetic nervous system of the organ is tensely excited, the pulse increases, the basal metabolic rate increases, the meridian current carrying amount decreases, and the electrical resistance value increases, resulting in an abnormal state. Then, the specific therapeutic action performed by balancing the functions of both nervous systems is
Made by acupuncture and moxibustion. On the other hand, when the parasympathetic nervous system is excited, the pulse rate is decreased, the basal metabolic rate is lowered, and indefinite complaints, headache, and shoulder / lumbar pain often occur, causing various disease states.

By the way, in general, muscle pain and stress due to overwork, exercise, and spraining of bruises can be easily diagnosed by visual inspection or palpation, and the positions of corresponding acupuncture points can be easily selected.

On the other hand, in the case of indefinite complaints, weakness, and pain in the lower back and shoulders, it is difficult for the patient to objectively recognize whether any part of internal organs is in a diseased state. In such a case, an acupuncture point representing each organ can be electrically measured and diagnosed for diagnosis in a patient suffering from an unknown cause. As this diagnostic device, a skin current measuring device (trade name: NeuRomet
er = neurometer) is known, and this device applies a high current of 200 μA to the acupuncture point (vessel) to know the impedance related to the degree of ataxia of the autonomic nervous system of various organs. It directly measures the size of.

FIG. 3 shows a state of use of the conventional inspection apparatus,
The equivalent circuit is shown in FIG.

In the electric circuit 2 shown in FIG. 3, a power supply battery 7 having a voltage Vo = 12V is provided in the housing 1, and a variable resistor 8 having a resistance Ro connected to the anode side of the power supply battery 7 is connected via an ammeter 3. An acupuncture point contact electrode 5 that comes into contact with the acupuncture point 6 is provided at the tip of the cord 4 drawn out into the housing. The ammeter 3 brings the electrode 5 for acupuncture point contact and the electrode 9 in the palm of the hand into contact with each other so that the current is 200 μm.
It is for calibrating to A and for directly measuring the reaction current value. The acupuncture point contact electrode 5 has a pointed shape in which a water absorbent material is enclosed in a hollow portion of a brass material, and the acupuncture point 6 of the wrist on either side 6
To one point while applying a slight pressing force. The middle electrode 9 is a brass cylindrical body, and reaches the cathode side of the power supply battery 7 via the cord 10.

In the above-mentioned use state, as shown in the equivalent circuit of FIG. 4, an impedance Ra of the contact portion of the acupuncture point 6 including the skin occurs. This impedance value is very small and does not fluctuate much during the measurement operation. When current is applied to the palm-mid electrode 9 held by the palm of the other side along the meridian in the body through the acupuncture point 6, the value of the impedance Rx of the meridian does not change during the measurement operation, but the value changes during the healing process after treatment. To do. It is extremely preferable and easy to grasp the electrode 9 in the palm with the palm in terms of the current measurement operation, and Rb is not so large because it contacts the conductor with a wide contact area of the palm. By measurement, I
= Vo / (Ro + Ra + Rx + Rb) holds, and the change in the meridian impedance Rx can be seen. However, in the mid-palm electrode 9, the nervous patient suddenly sweats, changes the grip force, and changes the contact area, so that the impedance Rb of the contact part between the central electrode 9 and the palm is measured. It is recognized that during operation, it fluctuates greatly from moment to moment.

[0008]

As described above, in the conventional inspection apparatus, the impedance Rb value generated at the contact portion of the palm-held electrode held by the palm forming the electric circuit changes from moment to moment. Therefore, the measured current value I changes greatly during the measurement, and the value is different each time the measurement is performed, so that the value is not reproducible and becomes extremely inaccurate. Therefore, in order to compensate for this inaccuracy, the measurement value of the total value repeatedly measured is taken, but of course it is difficult to accurately measure the abnormality of organ organs with this inaccurate value. is there.

Further, since the conventional inspection apparatus is a two-point type measurement system, a high current of 200 μA is passed through the power supply battery, but the allowable value of the patient measurement current is specified to be 10 μA, which is exceeded. It is hard to say that the current value is preferable from the viewpoint of electrical safety for the body. Then, when the driving current amount is lowered, the indication of the ammeter needle or the digital number becomes unclear, and in the case of the aged, the impedance Rb of the electrode in the palm increases and the current decreases because the skin is dry. Not only becomes inaccurate, but also it becomes difficult to read visually, and in some cases, it becomes unreadable.

Therefore, the present invention provides a meridian impedance measuring device capable of accurately measuring the meridian impedance without being affected by the impedance of the contact portion of the palm electrode held by the palm.

[0011]

A constant current that causes a constant current to flow from the acupuncture point contact electrode to the palm center electrode regardless of the impedance of the contact point of the acupuncture point contact electrode, the meridian impedance, and the impedance of the contact point of the palm center electrode between the electrode and the palm center electrode And a voltmeter for measuring the voltage of the impedance of the contact portion of the acupuncture point contact electrode and the impedance of the path.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a usage state of an impedance measuring device of the present invention, and FIG. 2 shows an equivalent circuit thereof.

In the apparatus of the present invention, as shown in FIGS. 1 and 2, a constant current source 15 is provided between the acupuncture point contact electrode 5 and the palm center electrode 9 by a constant current source 15 which keeps the current substantially constant even if the load impedance changes. The circuit is configured so that a constant current Io always flows. The constant current Io is set to an allowable value of the patient measurement current of 10 μA or less.

The constant current source 15 is provided, and the acupuncture point contact electrode 5 is connected to the tip of the cord 14 pulled out from the anode side of the constant current source 15. The constant current flowing from the acupuncture point 6 via the meridian flows to the palm-side electrode 9 held by the palm of the other side, and a circuit is formed from the palm-side electrode 9 to the cathode side of the constant current source 15 via the cord 10. There is. In this circuit, the voltage between the acupuncture point contact electrode 5 and the reference electrode 14 placed in the middle of the current circuit is measured by the voltmeter 11. As a result, the voltage V becomes V = (Ra + Rx) Io, and the impedance R of the contact portion between the palm and the electrode 9 in the palm is R.
Since b becomes irrelevant, it is completely unaffected by variations in impedance Rb. Therefore, by measuring the voltage V, the value of the target meridian impedance Rx and the change in Rx due to treatment can be accurately known. In particular,
Impedance R of the electrode in the palm due to the dry skin of an old man
Even if b becomes large, there is no problem and Rx can be accurately measured.

Further, since the constant current Io can be measured at 10 μA or less, it has a small effect on the living body and satisfies the electrical safety standard for medical equipment.

[0016]

According to the present invention, a stable three-point measuring system is constructed between each electrode by using a constant current source.
It has become possible to obtain an accurate meridian impedance Rb by measuring the potential difference which is rich in electrical safety, reproducibility and fidelity.

Further, the present invention establishes electrical safety for the human body by using 10 μA or less, and does not cause the conventional polarization phenomenon that would be expected at the time of high current of 200 μA. Since the unspecified stimulating effect on the biological reaction system via the autonomic nervous system is not electrically loaded, extremely stable reproducible and high fidelity measurement is possible. In particular, the measurement can be accurately performed even in the case of an elderly person whose skin has a dry contact resistance of the electrodes.
