Abstract

PROBLEM TO BE SOLVED: To improve a skin contact feeling and to perform application or sticking to the lesion of a wide range by forming a skin contact treatment tool by dispersing and including metal grains and semiconductor grains in a conductive paste-like material or a liquid-like material capable of forming a conductive film. SOLUTION: This skin contact treatment tool is formed from the one for which the metal grains (white dots) and the semiconductor grains (black dots) are dispersed in the conductive paste-like material. Since the metal grains and the semiconductor grains are electrically connected by the conductive material, a battery is formed at the time of being in contact with the skin and a current is generated inside the skin. At the time, the metal grains act as a positive pole and the semiconductor grains act as a negative pole. A metal used for the metal grains is the metal or the alloy for hardly receiving chemical change whose electrode potential is higher than the semiconductor grains and gold or the like can be cited. Also, as for a semiconductor used for the semiconductor grains, an n type semiconductor provided with a standard monopole potential lower than the metal used for the metal grains can be exemplified.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin treatment device for relieving stiff shoulders and back pain.

[0002]

2. Description of the Related Art In recent years, the number of patients suffering from chronic stiff shoulders and low back pain has increased. It is commercially available. These treatment tools have the effect of promoting blood circulation in the affected area by various principles and purifying locally accumulated waste.

On the other hand, Japanese Unexamined Patent Publication No. Hei 8-173554 discloses a therapeutic device based on a principle different from that of the above general therapeutic device.
Discloses a skin treatment device for healing muscle and nerve fatigue by electrical stimulation. The skin treatment device forms a biological battery when it comes into contact with the skin and provides a direct current, and is an excellent treatment device having a treatment effect equivalent to or higher than that of the above-mentioned home treatment device. Has been demonstrated.

[0004] A skin treatment device utilizing electrical stimulation has a drawback that it is difficult to maintain a constant current intensity. However, the skin treatment device has a metal and n as electrodes. This problem has been overcome by using a combination of mold semiconductors. In other words, in a combination of a normal metal and a metal, an insoluble salt precipitates on the electrode and the electrode deteriorates, whereas when a combination of a metal and an n-type semiconductor is used, the salt does not precipitate and the current is stabilized. It is clear that it can be supplied. In general, the positive electrode and the negative electrode are generally directly electrically connected, but by providing a protective resistance having a resistance value similar to that of the skin, metabolism at the skin contact portion is activated. Even if the resistance value of the affected part is significantly reduced, the change in the current value of the biological battery can be suppressed at most twice.

As described above, the skin treatment device disclosed in JP-A-8-173554 is extremely useful as a treatment device for treating stiff shoulders, back pain, and the like.

[0006] However, there are still points to be improved in size, skin contact, shape, etc. in the conventional skin treatment device using a battery element. Regarding the problems of such prior art,
An overview is given with reference to FIG.

FIG. 5 shows the general shape of a conventional skin treatment device. The skin treatment device includes a pedestal 1, a semiconductor 2, and a support 3, and is attached to the skin 4. The pedestal 1 is a pedestal made of a synthetic resin plated with gold, and functions as a positive electrode of the battery. On the other hand, the semiconductor 2 is held upright on the pedestal 1 and acts as a negative electrode of the battery, and the pedestal 1 and the semiconductor 2 form one battery.

As is clear from the figure, the skin treatment device has a large skin area to be covered compared to the area of the skin contact, and it is difficult to apply a plurality of skin regions to mutually adjacent sites.

In addition, in the shape shown in FIG. 5, it is extremely difficult to attach to joints such as elbows and knees, and in addition, it may cause pain when attached to joints, soles, etc. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a view showing an embodiment of the skin treatment device according to the first aspect of the present invention, wherein fine metal particles (open circles) and fine semiconductor particles (black circles) are dispersed in a conductive paste-like substance. It shows how it is.

The skin treatment device according to the first aspect is disclosed in
Unlike the skin treatment device described in 173554, it is used by applying it to the skin. Therefore, the skin treatment device can be applied to a desired body part. Also, since it is only applied to the skin, there is almost no discomfort at the time of skin contact as compared with a conventional skin treatment device, and there is no pain at the time of skin contact.

Since the metal fine particles and the semiconductor fine particles are electrically connected by a conductive substance, a battery is formed when the fine particles come into contact with the skin, and a current is generated in the skin. In the battery, the fine metal particles function as a positive electrode, and the fine semiconductor particles function as a negative electrode.

The metal used for the fine metal particles serving as the positive electrode is a metal or an alloy thereof that is hardly subjected to a chemical change and has an electrode potential higher than that of the semiconductor fine particles serving as the negative electrode. For example, gold is a typical example. .

The semiconductor used for the semiconductor fine particles may be any n-type semiconductor having a lower standard unipolar potential than the metal used for the metal fine particles. Preferred n in the present invention

Further, by using a conductive paste-like substance impregnated with an ionic drug, a so-called iontophoresis action occurs, and the active ingredient of the drug is ionized.
It is also possible to forcibly penetrate the active ingredient ions into the skin current path by the electric repulsive force of the biological battery.

In this case, as shown in FIG. 4, it is more effective to apply metal fine particles serving as a positive electrode in the form of a foil beforehand at the center of the support to be applied.

FIG. 2 shows the skin treatment device according to claim 1 applied to the skin.

Since the battery is not formed unless the metal fine particles and the semiconductor fine particles are in contact with each other, the battery must be spread and applied to the skin surface so that the metal fine particles and the semiconductor fine particles are in contact with each other.

FIG. 3 shows a skin treatment device according to claim 2 attached to the skin. The skin treatment device according to claim 2 is
A skin treatment device according to claim 1 is applied to a support.
