[0007]

However, in the conventional electrode conductor using a silicon molded product or a polyethylene terephthalate sheet as the above-mentioned conventional support member, it may bend and warp when attached to a complicated curved surface of a human body such as a neck. Since the electrodes cannot be completely adhered to the treatment site, the current-carrying area is reduced, and when using a low-frequency treatment device, the strength between the electrodes due to unpleasant tingling sensations and differences in the degree of adhesion is low. There was a problem of feeling the difference in strength.

[0008] It is an object of the present invention to provide an electrode conductor that can sufficiently adhere each electrode to a treatment site even when the electrode conductor is stuck to a part of the human body that is complicated to some extent.

As shown in FIG. 1, the electrode conductor of the low-frequency treatment device of the present invention has a fabric 2 attached to both sides of a support member 1 made of a foamed resin material by heat fusion. The electrode part 2 is mounted on the support member 1 so that the electrode part 3 is flush with the electrode part 3.

Hereinafter, a method of manufacturing the electrode conductor of the low frequency treatment device according to the present invention will be described with reference to FIGS.

The support member 1 of the present invention is formed of a foamed resin material, which is a material having both flexibility and elasticity, unlike the conventional material such as silicon. The foamed resin material is, for example, polyurethane, natural rubber, chlorobrene rubber, nitrile rubber, butyl rubber, silicone rubber, fluoro rubber, chlorosulfonated polyethylene, isoprene rubber, butadiene rubber, styrene butadiene rubber, ethylene propylene rubber, polyvinyl chloride, It is a sponge having an open-cell structure made of an ethylene-vinyl acetate copolymer resin, phenol resin or the like. These foamed resin materials can be easily cut, punched, and heat-compressed, which is convenient for mass production. Further, the cost can be reduced as compared with a conventional silicon molded product.

[1] The fabric 2 is bonded to both surfaces of the support member 1 by heat fusion. The cloth 2 is a composite woven cloth of chemical fibers (among others, Gore-Tex) such as cotton woven cloth, hemp woven cloth, silk woven cloth, and polyester. By attaching the cloth 2, the deterioration of the supporting member 1 due to use is prevented, and by making the portion in contact with the skin a cloth, the supporting member 1 such as a foamed resin material is prevented from being discomfort due to irritation to the skin and is comfortable. You can feel it. It is also excellent in water absorption.

[2] The processed support member 1 is cut. The size of each support member 1 to be cut is
The width is 4 to 8 cm and the length is 11 to 15 cm so that it fits on the shoulders and waist.

[3] The above-processed and cut support member 1
At appropriate intervals, a plurality of heat-compressed recesses 4 are formed substantially linearly in a shape (horizontal 1-3 cm, vertical 4-6 cm) similar to the shape of the electrode portion 3. At this time, the depth of the groove subjected to the thermal compression processing corresponds to the thickness of the conductive gel adhesive pad 11.

[4] A hole 5 for connecting to the lead wire 12 is formed in a part of the portion subjected to the heat compression processing.

[5] On the other hand, an electrode sheet 8 having a conductive portion 7 printed on an insulating sheet 6 is formed. This electrode sheet 8
Are soft plastic sheets collectively, and individually, PVC, polyethylene, polystyrene,
It is a sheet made of polypropylene, polyamide, methacryl, or the like, or a sheet made of another nonwoven fabric.

[6] The electrode sheet 8 is cut.
The size of one electrode sheet 8 to be cut is 1-3 c in width.
m, length 4-6 cm.

[7] Holes 9 are formed in the electrode sheet 8 by cutting.
And attach the connection terminal 10.

[8] A conductive gel adhesive pad 1 having a shape similar to the shape of the electrode sheet 8 (1 to 3 cm in width and 4 to 6 cm in height)
1 is cut.

[9] The conductive gel adhesive pad 11 is attached to the electrode sheet 8 to form the electrode section 3.

[10] The above-mentioned electrode section 3 is
Is adhered to the concave portion 4 formed by using an adhesive or the like. At this time, the connection terminal is passed through the hole 5. At this time, the fabric and the conductive gel adhesive pad have a structure in which the surfaces are flush with each other, so that when worn on a human body, a comfortable touch can be obtained.

[11] The connection terminal 10 of the electrode section 3 and the lead wire 11 are connected.

[0028] With the above configuration, complex modifications, such as in FIG. 5, with respect to deformation of bending the side electrodes are arranged warps (arrow A) and opposite side (arrow B) However, as shown in FIG. 6, this can be dealt with by contracting the central portion in the direction of arrow X and extending both ends in the Y direction.
In addition, the deformation opposite to the deformation in the above example can be dealt with by the opposite contraction and expansion. For this reason, when sticking the electrode conductor main body to the treatment part of a human body, even if the site | part has a complicated curved surface to some extent, it can be stuck to a human body reliably. In addition, since the adhesion area of the electrode does not decrease due to the close contact of the adhesive pad, the tingling discomfort is eliminated.

Another example is shown in FIGS. In FIG. 7, the basic manufacturing method is the same as described above, but by arranging a plurality of (row) electrodes in the same conductor,
Many treatment sites can be stimulated with one attachment of one guide. In FIG. 8, the basic manufacturing method is the same as that described above, except that the support member is made circular, and each electrode is formed in an annular shape having a different diameter, concentrically, and arranged concentrically. By arranging the electrodes in this manner, the electrodes can be deformed corresponding to the uneven shape of the treatment site of the human body.

[0030]

Even if the electrode conductor is bent to the side with the electrode part and is warped in the direction opposite to the bending direction, complicated overlapping such as bending and elongation warping is caused by the elasticity and flexibility of the support member of this electrode conductor. Since the electrode portion is deformed in accordance with the shape, the electrode portion can be securely brought into close contact with the human body. In addition, the portion of the electrode conductor that comes into contact with the skin is made of fabric, so that it has water absorption.The electrode portion of the electrode conductor is mounted so as to be flush with the support member, so it can be applied to the human body. When worn, there is a pleasant touch.

[0031] In addition, in the present onset Akira, stuck on the support member
Since a plurality equipped with front Symbol electrode portion is sandwiched between the attached fabric construction, not only can stimulate many treatment site at one electrode Shirubeko, it is possible to complex treatment.

[0032]
