DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin treatment device which is used in contact with the skin to restore health, and more particularly to a skin treatment device which is effective for relieving muscle stiffness and indefinite complaints.

[0002]

2. Description of the Related Art Conventionally, as an instrument for treating stiffness and pain of muscles such as shoulders at home, a biological battery is formed at the time of skin contact, and an ion that heals muscle and nerve fatigue by applying a weak DC electromotive force to stimulate stimulation. Penetrator (JP-B-61-55979, JP-B-61-55980, JP-B-62-32944,
Japanese Utility Model Publication No. 3-50927). This ion penetrator electrically connects a semiconductor crystal to a metal having a higher standard monopolar potential than the semiconductor crystal. This ion osmosis device provides a continuous electromotive stimulus to muscle and nervous system tissue by stable electromotive force after skin contact, and there is little deterioration even after prolonged skin contact, making it a practical treatment tool for stiffness and pain As a high therapeutic effect. The mechanism for eliminating such stiffness and pain is considered to be due to current stimulation of the biological battery. For this reason, in order for the ion permeator to obtain a strong therapeutic effect, the current of the biological battery may be increased. However, when the muscle and nervous system tissue are physiologically activated by the skin cell energization of the biological battery, the impedance between the electrodes in the skin is significantly reduced. As a result, the current in the skin increases, resulting in overstimulation of the skin tissue, which may result in skin damage. To solve this problem, as shown in FIG. 6, a protection resistor 13 in which a first element 11 serving as a metal positive electrode and a second element 12 serving as a semiconductor negative electrode are arranged in a non-contact region with each other is provided. A skin treatment device electrically connected via a cable has been proposed (JP-A-8-173554). Hereinafter, the skin treatment device shown in FIG. 6 will be described. The first element 11 is obtained by plating a copper disk having a projection at the center with gold, and becomes a positive electrode of a biological battery when used (at the time of skin contact). Second
The element 12 is an n-type semiconductor in which the surface of a zinc ring having a hole in the center is oxidized to be zinc oxide, and serves as a negative electrode of a biological battery at the time of skin contact. The protection resistor 13 is made of an epoxy-based synthetic resin in which carbon powder is dispersed,
Is formed of a film uniformly applied to the surface (the upper surface in the figure) and dried. The protection resistor 13 is connected to the second element 1.
2 is adhered to the upper surface. The external circuit of the biological battery as a skin treatment device is connected by a protective resistor 13. 17 is an adhesive cloth and 18 is skin. A method for producing a skin treatment device will be described. First, an epoxy-based synthetic resin serving as a protective resistor 13 is uniformly applied to the surface of a flat portion, which is the upper surface of the disc-shaped first element 11, and then the second element 12 is dried before the synthetic resin is dried. Is placed on the flat portion, and then the synthetic resin is dried. By this operation, a skin treatment device in which the first element 11 and the second element 12 are laminated with the protective resistor 13 interposed therebetween, and the center projection protrudes from the center hole of the second element is completed. Is done. The conventional skin treatment device as shown in FIG. 6 achieves the initial purpose of eliminating indefinite complaints such as stiffness of muscles such as shoulders and low back pain, but has an epoxy for forming a protective resistor in the manufacturing process. It is necessary to work to uniformly apply the synthetic resin. This uniform application requires not only skill but also time and labor. In addition, there is a problem that the manufacturing process becomes complicated because it is necessary to place the second element on the upper surface of the resin before the applied resin is dried, and then to dry the second element. As a result, there is a point to be improved in the conventional skin treatment device in order to efficiently produce a product of uniform quality in large quantities at low cost and efficiently. An object of the present invention is to make it possible to easily produce products of uniform quality in large quantities and at low cost.

And a second element 2, a conductive element (a resistor in this example) 3 for electrically connecting the two elements, and a pedestal 4. The first element 1 and the second element 2 and the resistor 3
It is provided on the upper surface of the pedestal 4 in a planar manner. A first element 1,
Each of the second element 2 and the resistor 3 is formed on an insulating substrate 5 such as a ceramic substrate in a thin film form integrally with the substrate. The first element 1 is made of a conductive metal such as a noble metal, and serves as a positive electrode of a biological battery when a skin treatment device is used, that is, at the time of skin contact. In the example shown in the figure, the first element 1 is a conductive element made of a film formed by baking gold paste on the substrate 5, for example. The second element 2 is made of an n-type semiconductor, and serves as a negative electrode of a biological battery at the time of skin contact. In the example shown in the figure, the second element 2 is a semiconductor element made of a zinc oxide film formed by baking a zinc paste on the substrate 5, for example. The resistor 3 (in FIG. 2, the resistor is shown by stippling and the first and second elements 1 and 2 are distinguished from each other in the drawing). 2 is electrically connected,
It has a current limiting function. The positional relationship between the first and second elements 1 and 2 and the resistor 3 is such that the first and second elements are arranged at both ends of the resistor with the first and second elements located at both ends of the resistor.
The second elements 1 and 2 are connected respectively. As a method of manufacturing the first and second elements 1 and 2 and the resistor 3, for example, the first and second elements 1 and 2 are formed on the upper surface of the original substrate by a method such as silk printing.
After the resistor 2 and the resistor 3 are sequentially formed in a strip shape, the original substrate is cut into a chip shape having a predetermined size. This manufacturing method is the same as the manufacturing method of the chip resistor of the electronic component, the manufacturing is easy, and the manufacturing cost can be reduced. The pedestal 4 is made of an insulating member such as a synthetic resin, and is formed in a disk shape in the illustrated example. The pedestal 4 has a mounting recess 4a formed on the upper surface thereof, and the first and second elements 1 and 2 and the resistor 3 integrated with the substrate 5 are mounted in the mounting recess. An adhesive is used to fix the position of the substrate 5 in the mounting recess 4a.

[0005] In the method of manufacturing a skin incision treatment tool, a substrate 5 having first and second elements 1 and 2 and a resistor 3 on its upper surface is fitted into a mounting recess 4 a of a pedestal 4 and fixed with an adhesive. . Regarding the method of using the skin treatment device, as shown in FIG. 1, the skin contact surface 4 b of the pedestal 4 is strongly pressed against the skin 8 by using an adhesive cloth 7 on the surface of the skin 8 where there is stiffness or pain. Hit and fix.

The principle when the skin treatment device according to the present invention is in skin contact with the skin will be described with reference to FIG. Electrons e ⁻ flowing from the second element 2 made of an n-type semiconductor to the first element 1 via the resistor 3 flow into the skin 8 to cause a reducing action. On the other hand, holes h ⁺ generated in the n-type semiconductor, which is the second element 2 deficient in electrons e ⁻ , are concentrated on the skin contact surface due to the internal electric field of the Schottky barrier generated on the skin contact surface, Is ionized, and penetrates into the skin 8 together with the cation S ⁺ by an internal electric field. The holes in the skin 8 have an oxidizing effect. This oxidizing action is stably continued by the action of preventing the inflow of electrons and negative ions from inside the skin 7 of the Schottky barrier in contact with the skin, and the electromotive force of the biocell is generated for a long time. Reference numeral 6 denotes a high electric field region.

According to the illustrated skin incision treatment tool, the first element 1, the second element 2, and the resistor 3 are formed on the same plane and are not configured to be vertically overlapped. It is simple, can be manufactured in large quantities, can reduce product cost and uniformity of quality without skill, and can perform manufacturing operations simply, quickly and efficiently.

The constituent members of the first element 1 and the second element 2 are not limited to gold paste or zinc paste. Resistor 3
1 is half the thickness of the first and second elements 1 and 2 in FIG. 1, but is appropriate depending on the resistance value and is not limited to the illustrated one. Although a resistor is used as the conductive element 3 in the above example, the resistor is not necessarily required. The conductive element 3 is formed by using a method of coating a conductive member such as carbon on the substrate 5. By such a method, the resistance value of the conductive element can be set in a range from 0 ohm to an arbitrary resistance value, and a current limiting function can be added. In other words, the resistance value of the conductive element 3 can be set to 0 ohm or an appropriate value of 0 ohm or more in order to add a current limiting function, depending on the manufacturing method. The conductive element 3 can electrically connect the first and second elements 1 and 2 and can add a current limiting function to the conductive element 3. Further, as a method of forming the conductive element 3, a resistance value of 0 ohm can be realized by using the same member as the first element 1 or the second element 2 instead of the carbon coating described above. Pedestal 4
Is not limited to those formed of a synthetic resin. The pedestal made of an insulating member includes one that covers the main body with an insulating member. In the above example, the method of fixing the substrate 5 to the pedestal 4 is described using an adhesive, but the method is not limited to this example. For example, there is a fixing method using heat. That is, in this fixing method, first, the substrate 5 is heated, and the heated substrate is brought into contact with the synthetic resin pedestal 4.
When the contact surface of the pedestal that contacts the back surface of the substrate is melted, the back surface and the contact surface are bonded to each other.
