Description

Detailed Description of the Invention

[0001]

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

[0002]

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

On the other hand, Japanese Patent Application Laid-Open No. 8-173554 discloses a therapeutic device based on a principle different from the above general therapeutic device.
The publication discloses a skin treatment device for healing fatigue of muscles and nerves by electric stimulation. The skin contact treatment device forms a bio-cell when contacting the skin and allows a direct current to flow, and is an excellent treatment device having a therapeutic effect equivalent to or higher than that of the above-mentioned household treatment device. Has been proven.

The skin treatment device using electrical stimulation has a drawback that it is difficult to maintain a constant electric current strength, but the skin treatment device uses metal and n as electrodes.
This problem is overcome by the combination of type semiconductors. That is, in the case of the usual combination of metal and metal, salt which is an insulator is deposited on the electrode to prevent continuous supply of current, whereas in the combination of metal and n-type semiconductor, the The holes generated in the semiconductor when electrons flow out to the metal are forcibly pushed out to the skin contact surface by the internal electric field of the Schottky barrier formed on the skin contact surface, and to the skin as free holes and semiconductor ions. Since it flows out, excess electrons in the skin are neutralized, and it becomes possible to stably supply an electric current. As described above, Japanese Patent Laid-Open No. 8-173554
The skin-contacting treatment tool disclosed in Japanese Patent No. 3 is extremely useful as a treatment tool for treating stiff shoulders, low back pain and the like.

However, the conventional skin-contacting treatment instrument using the bio-battery element has some points to be improved in size, skin-contact feeling, shape and the like. The problems of the prior art will be outlined with reference to FIG.

FIG. 5 shows a general shape of a conventional skin-contact therapeutic device using a bio-cell device. FIG. 5 (a) is a sectional view in a state of skin-contact, and FIG. 5 (b) is a plan view. The skin treatment device has a positive electrode (gold) 11 and a negative electrode 12 (n-type semiconductor) connected to a current limiting resistor 13 on a ceramic substrate 15, and is fixedly integrated in a recess 14a of a pedestal 14 from an adhesive tape. It is affixed to the skin 17 by the support 16 that is formed. The support 16 and the skin 17 are not shown in FIG.

As is clear from the figure, the skin contact treatment device has a large skin area to be covered as compared with the area of the skin contact, and therefore it is difficult to attach a plurality of skin contact parts to adjacent sites.
Further, with such a shape, it is extremely difficult to apply it to joints such as elbows and knees, and further, it may cause pain when applied.

In order to facilitate attachment to joints such as elbows and knees, Japanese Patent Laid-Open No. 2000-237324 discloses a combination of a metal used as a battery element and an n-type semiconductor in an elongated metal piece and an elongated n-type. There has been proposed a skin contact treatment tool which is configured by a combination of semiconductor pieces and in which the metal piece and the semiconductor piece can rotate and / or slide with respect to each other.

[0009]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The skin treatment device disclosed in No. 7324 has a shape that flexibly conforms to the bending of joints and the like, but is adhered by a paper / cloth support to which an adhesive such as a plaster is attached, so that it has a wide range. It was not suitable for sticking to. Furthermore, it was not suitable when the site to which the support was attached contained a wound.

Therefore, there has been a long-felt demand for a skin-contacting treatment instrument having a shape that is flexibly adapted to the bending of joints and the like, and the size thereof can be freely changed, and the skin-contacting feeling is good.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to treat a pain site widely as a face rather than as a point as in the conventional case, and a skin contact that can be attached to a joint part. The purpose is to provide a therapeutic device.
