The present invention relates to a plurality of electrodes used in the therapeutic method that can see the efficacy through the current to the organism having a skin.

When direct current is used by using a conventional electrode, ionic burns are frequently generated on the cathode side of the patient's skin. These burns are not caused by an increase in temperature, but are caused by an electric current flowing through the skin.

This burn will take a relatively long time, resulting in unsightly and extremely undesirable scars. However, according to the present invention, at least the cathode portion in contact with the skin is covered with a felt-like material with a thickness of 3 mm or more, appropriately wetted, and the relationship between current and time is limited within a certain range depending on the treatment method Inevitably, the ion mobility image can be avoided.

Optionally, the use of a cathode structure increases the size of the anode, making the treatment current much higher while eliminating discomfort.

The negative electrode and the positive electrode may be mixed and used.

For centuries, many types of electrodes have been developed for the electrical treatment of the human body. The electrodes are usually placed on the skin in relation to the affected area.

Such electrotherapy has a wide range of applications. For example, in the past, direct current therapy has been used because of the polarity effect of ionizing molecules that can transport the ionized molecules through the skin.

This phenomenon is called ion transport, which has been used to inject drugs into the patient's skin or simply to add water.

More specifically, zinc and copper ions can be used to treat skin infections and chlorine ions can be used to clear skin scars. Furthermore, vasodilators can be used to treat rheumatic and peripheral vestibular diseases, and skin anesthesia can be performed using ion transport of local anesthetics. This means that an anesthetic effect can be obtained by carefully selecting a portion of the live animal and galvanizing it.

In general, these electrodes were merely used as components and did not take into account the undesirable side effects of electrical current on the skin. As an example, in US Pat. No. 562,765, the primary goal was simply to reduce contact resistance with the skin.

According to the report of 'Archives of Darmatology', Vol. 98, No. 5, 505-7P, there is a method of electrolysis of feet or hands to have long-term effects. However, this method only uses a 2in ² lead sheet as an electrode. In other words, the electrode is placed in a dish-shaped container filled with water so that the palm or sole of the foot can be locked and the other electrode is placed on the palm or sole of the foot. The results of this experiment show that sweating is suppressed where current flows through.

Although the ion transfer therapy as described above was effective, direct current through such a conventional electrode would cause ion transfer burns at the site of the cathode. The findings of Lemming and Howland in the Journal of the American Medical Association, Vol. 214, give examples of some burns, but these wounds There is no mention of preventive measures. In spite of the great effect of the ion transfer treatment, the ion transfer treatment method was not favorably accepted, although various advantages can be obtained in using and developing the method in the medical field.

Therefore, there is a need for a convenient and effective method and device for preventing ion mobility burns occurring while applying electrical energy to human skin. As described above, the present invention satisfies this need.

The present invention relates to a method and apparatus that can greatly minimize or eliminate adverse side effects of locally applying electrical energy to human skin.

The electrode arrangement of the present invention consists of two conducting surfaces which are adjacent to each other and are supplied with currents of opposite polarities, respectively. Adjacent electrodes can prevent current from flowing through or through an electric shock organ, such as the heart.

The method and apparatus of the present invention can be used in connection with electrotherapy for antiperspirant as a prevention of ion-moving burns, but it should be noted that the method and apparatus are similar to those of the above-mentioned examples. It can be used properly for treatment.

One side effect that can be eliminated with the electrode arrangement according to the present invention is ion-moving burns. This is possible by inserting a relatively thick porous moisture material between the cathode and the skin.

Another side effect, such as pain when passing currents or tingling tingling, can be made much less. This can be done by increasing the anode area.

The same effect can be obtained by using a porous material and mixing and arranging the size of the anode and the cathode to be smaller.

The present invention will be described in detail with reference to the accompanying drawings.

Referring to the first drawing (1), the conductive electrode can be flexible or hard, and is generally made of metal such as stainless steel or aluminum.

Marked as (2) refers to the skin and the insert (4) is to be loosely in contact with the bottom of the electrode (1) to be replaced or discarded after use.

What can be used as the insert 4 is felt which can be purchased anywhere. The thickness defined as an important factor in the present invention is not generally available thickness but can be specially customized.

The quality control requirement in the manufacture of this material is that it should never contain scraps or the like.

When it is necessary to increase the size of a factor having a relationship of (current) x (treatment time), the thickness may be 3 mm or more.

The flexible electrical conductor 5 may be electrically connected to the electrode 1, and the shape of the electrode 1 may be a metal plate or a conductive plastic such as silicon, or a snap fastener.

2 and 3 illustrate the electrode arrangement. Referring to FIG. 2, the porous material 4 is positioned under the cathode 1. The electrode 6 in FIG. 2 is 1-sq cm away from the electrode 1 and a conductor 7 is used to connect the anode 6 to the power source 8, which is simply a metal electrode thick. May or may not insert a thick porous insert 4.

The power source 8 simply uses a DC power source such as a battery, and generally requires a current in the range of 1-20 milliamps. Known adjustable resistors are included in the power source 8 to allow the user to generate an appropriate current for the required process.

In order to suppress sweating, the current density of the anode should be 1 / 20-1 / 2 milliampere per cm 2. Of course, in applying the present invention as described above, the actual current density and treatment time should be appropriately selected. It must be adapted to special circumstances. The actual values herein are written as one therapeutic example in which the present invention can be implemented.

The power supply 8 is likewise known constant current power supply and has the same requirements as described above, so that the user can select the constant current value required. As another element of the proposed device, the maximum current to be applied should be limited.

The power supply may be in the form of a unidirectional pulse or a constant current, but not an alternating current or a high frequency current at a commercial frequency.

The arrangement of the electrodes 1 and 6 can take many forms, depending on the treatment area and the designer's choice. You may install these electrodes in the frame <tangential line 9 of FIG. 2> which is an insulator.

This can be used conveniently to suppress the sweating of the hands or feet.

As another method, the anode 6 may be installed in the palm to suppress sweating of the palm. At this time, the cathode is installed on the back of the hand or the wrist.

The attachment device 3 is used to fix the electrodes 1 and 6 to the frame 9.

Of course, the negative electrode can be arranged in harmony with the positive electrode, such as in the glove. Sweating is suppressed at the anode, where the cathode is placed adjacent to the current return. In the case of the foot, a similar device may be used, such as stockings. This gives a slight pressure between the two electrodes and the skin so that it is fixed in place.

To suppress the sweating of the armpits, bend the anode and attach it to the underarms. At this time, close the cathode or insert an electrically insulating material between the cathode and the anode to occupy half of the area in the armpit.

Elements 5, 7 and 8 in FIG. 3 are as described above, but the anode 10 is made relatively large and the cathode 1 'is made relatively small. The shape of the anode is rectangular rather than square as described above. If necessary, the electrode may be in any shape.

The electrode arrangement shown here is useful for suppressing sweating of the hand. The electrode 10 is placed on the palm of the hand and the cathode 1 'is placed on the finger of the same hand.

Indeed, when suppressing sweating or performing similar treatments, it is known that conventional devices can cause incident ion burns at the current densities necessary to achieve the desired results.

In the present invention, the image phenomenon is separated, so that the metal terminal or the metal plate of the cathode is properly covered with a thick felt pad so that the ion mobility image can be avoided by limiting the current x time element.

The nature of the thick felt electrode has been described, which is used by soaking it in tap water. Distilled or demineralized water can also be used.

For example, the palm is treated with an anode having an area of 90 cm 2, where the cathode is 30 cm 2 in contact with the finger and the thickness of the felt is 6 mm.

If a current of 15 milliamps is passed for 10 minutes, no ion-moving burn occurs. Alternatively, the processing time may be 20 minutes at 7.5 milliamps and 40 minutes at 3.75 milliamps.

The corroborating fact is that as the current flows into the skin 2, certain particles or substances move from the metal electrode 1 into the insert 4. These particles or substances must not migrate completely towards the skin. The reason is that if you move, you will be burned. Therefore, the thickness of the insert acts as a moving barrier or retarder, preventing the burn-causing particles from reaching the skin within the time of treatment at a given current.

Since inserts are not easily reproducible, they should be discarded after practical use of the negative inserts for treatment. The insert 4 is made of natural fibers such as wool or cotton without metal.

Kita Equivalent synthetic fibers such as viscose nylon and polyester can also be used. Alternatively, porous materials such as foams or sponges may also be used.

Induction of antiperspirant electrical effect does not appear immediately after treatment, but rather about two weeks after 1-2 weeks to continue for 6 weeks.

The skin area where the therapeutic effect is exhibited shows a leaching or diffusion effect in a range larger than that of the part directly contacting the electrode. The fact that the experimental device has been confirmed is that current spreading itself is extremely insignificant compared to the spread of antiperspirant effects. Therefore, the inhibitory effect may be attributed to the chemical action of producing keratin plugs on sweat glands.

Since the treatment spreads to the limited area of the skin that is in contact with the electrode, flatness occurs on the palms or soles of the feet regardless of the curvature of the skin. In the conventional electrode treatment method, such a diffusion effect is not seen or recognized, because all these methods are not mentioned.

In FIG. 2 and FIG. 3, the spacing between each electrode pair can be close as long as current does not pass through the skin but between the electrodes.

A battery is used as the power source 8 to ensure maximum stability and convenience to the user. The required voltage varies with the total resistance of the load circuit and typically uses 45 volts. Small batteries with these full voltages are available on the market and are suitable because they provide only a few milliamps of current.

An advantage of the adjacent electrode arrangements in FIGS. 2 and 3 is the fact that at the start of treatment the user can rapidly increase the treatment current without feeling bad. It is desirable to increase the current at zero or a low value at the beginning of treatment. By placing electrodes adjacent to each other, the current can be increased to a therapeutic amplitude within 1 second.

If you use electrodes with a spacing of several centimeters, such as attaching to other parts of the body, the current should be gradually increased.

Allow the user or device operator to gradually and gradually adjust the current-controlled potentiometer to avoid pain and shock. However, the same effect on the prevention of burns can be obtained also in the method of treatment using electrodes with a long distance.

If the distance between electrodes is not close, the current should be gradually reduced at the end of treatment.

Inhibition of sweating occurs mainly at the positive electrode, but the degree of suppression is small at the negative electrode.

Antiperspirant, that is, the basic time required for the treatment of latent treatment is 40 minutes, the first six treatments, in this case once every two days is good.

You do not need to care for your skin before electrotherapy. However, to achieve consistent results, it is necessary to scrub the skin where the electrode will be installed with alcohol.

FIG. 4 is a diagram in which electrodes are alternately configured for each terminal. In this figure, the small positive electrode 14 and the negative electrode 15 are mixed, and the size of these electrodes is about 1 cm 2 and is several mm apart from each other. It forms the necessary felt layer between all electrodes and the skin, and forms a connection system with the conductor 16 on the anode and the conductor 17 on the cathode, so that all electrodes and power sources (8) ).

FIG. 5 is also a mixed electrode configuration method, in which the positive electrode 18 has a larger area than the negative electrode 19, and other parts of the mixed electrode may use the same configuration method as in FIG.

In making the positive electrode area larger than the negative electrode in the present invention, there is actually an allowable limit in the difference in area. That is, the ratio is about 3: 1. As in the case of FIG. 3, the area of the anode is 90 cm 2 and the area of the cathode is 30 cm 2.

In the case of simultaneous treatment for both hands or the time limit of the head, two sets of electrodes are connected to the constant current power source 8 as shown in FIG. However, each uses a separate constant current power source and connects a separate battery for each power source to obtain output. This makes it possible to vary the current in each hand to provide a compensation for the different sensitivity of each hand.
