2. Description of the Related Art A therapeutic electrode of this kind is disclosed in Japanese Utility Model Application Laid-Open No. 63-40955.
As shown in Japanese Patent Application Publication (A61N1 / 32), a low frequency emission electrode, an affected part contact pad and a heater are built in the frame, and a part of the affected part contact pad is exposed from the frame. Are known. When the electrode is normally used, the affected area contact pad is wetted with water to make it conductive, and the electrode is fixed to the user's body by a belt to treat the affected area.

However, with such a configuration,
Since the electrode is not flexible, if the affected part has a curved surface, even if the whole surface of the electrode is brought into contact with the affected part, only a part of the electrode is in contact and current flows only from a part, so the therapeutic effect is diminished. There was a problem that said.

[0004] In such a configuration, the contact pad is heated by the heater. If the pad is used several times, the contact pad tends to become brittle due to a change in temperature. There is a problem that the diseased part abutment pad adheres to the pad and becomes very dirty. When the contact pad is replaced, the frame must be disassembled and replaced, which is very troublesome and troublesome. If the frame cannot be disassembled, the entire electrode must be replaced, which is very expensive for the user.

SUMMARY OF THE INVENTION The present invention provides a therapeutic electrode capable of performing thermal treatment in close contact with a diseased part of a user, in which a part in contact with the diseased part can be easily replaced. It is an object of the present invention to provide a therapeutic electrode having a high quality.

[0006]

SUMMARY OF THE INVENTION The present invention is directed to a heating element which is attached to a flexible base and generates heat by passing an electric current, and which is attached to the heating element and printed with carbon so as to be lower than carbon. A sheet-shaped electrode sheet through which a frequency treatment current can flow, and a gel-like adhesive conductive pad attached to the electrode sheet and having an adhesive property, wherein the heating element generates a heat by passing a current. And a heating element, an electrode sheet, and an adhesive conductive pad are sequentially stacked from the base.

Further, the heating element is pattern-printed so as to be stretched over the entire surface while folding back the line portion.

[0008] The adhesive conductive pad is removably attachable to the electrode sheet.

When a user uses a treatment electrode, the entire surface of the electrode is bent and attached to the affected part, and a treatment current is supplied and the heating element is heated to perform treatment.

[0010] Further, since the heating element is pattern-printed by folding back the line portion, the entire electrode is warm and can be bent along the line portion, so that treatment can be performed without impairing flexibility.

[0011] Even if the adhesive conductive pad becomes contaminated after several treatments, the adhesive conductive pad alone can be removed from the electrode sheet and the adhesive conductive pad can be replaced with a new one.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

Reference numeral 1 denotes a flexible vinyl chloride insulating film serving as a base for a therapeutic electrode.
A heating element 2 having a resistance and generating heat by passing a current is attached to the heating element 2, and the heating element 2 is printed in a pattern with the line portion 3 being folded over the entire surface as shown in FIG. 4. . The current flows through the heating element 2 through the heating cord 4, and the current flowing through the heating cord 4 is supplied by an AC adapter (not shown).

FIG. 4 is a pattern diagram of the line portion 3 of the heating element 2. The pattern of the line portion 3 is formed such that the density of the central portion is higher than the density of the peripheral portion, and the conductive portion will be described later when energized. The pad 7 is wired so that the central portion is at a higher temperature than the peripheral portion.

FIG. 5 shows another embodiment of FIG. 4, which is also wired so that the central part of the conductive pad 7 becomes high in temperature.

FIG. 6 shows another embodiment of the present invention, in which the cross-sectional area of the central line portion 3 is reduced and reduced separately from the method of densely wiring the line portions 3 and raising the temperature. The resistance value is larger than that of the peripheral portion, and accordingly, the amount of heat generated when a current flows is larger in the central portion than in the peripheral portion.

5 is attached to the heating element 2 and is separated from the heating cord 4 by a treatment cord 6 separately from the A.
An electrode sheet through which the C adapter can flow as a power source. The electrode sheet 5 is formed by carbon printing on a rubber sheet.

Reference numeral 7 denotes a gel-like adhesive conductive pad attached to the electrode sheet 5. The adhesive conductive pad 7 has an adhesive property, and can be attached to an affected part to be treated by a user. Further, the adhesive conductive pad 7 can be attached to the electrode sheet 5 so that it can be replaced with a new one when the number of times of use increases and becomes dirty.
Here, the electrode sheet 5 and the adhesive conductive pad 7 are collectively referred to as an electrode 8.

Reference numeral 9 denotes a main body of an electrotherapy device through which a therapeutic current can flow, and a heating switch 10 and a therapeutic switch 11 provided on the main body 9 are turned on, so that the AC adapter is used as a power source, and the heating element 2 and the heating element 2 are turned on. The electrode sheet 5 is energized to perform thermal treatment and electric treatment. Also, a battery (not shown) is built in the main body 9, and when the thermal switch 10 on the surface of the main body 9 is turned off, only the electrode sheet 5 is energized using this battery as a power source to perform electrotherapy. be able to.

Next, the operation will be described.

When a treatment is performed, A is operated by operating the main body 9.
Using the C adapter as a power source, current flows through both the heating element 2 and the electrode sheet 5 via the cords 4 and 6. Then, the user sees that the adhesive conductive pad 7 has reached an appropriate temperature, attaches the electrode 8 to the affected part, and performs electric therapy and thermal treatment simultaneously. At this time, the temperature of the central portion of the adhesive conductive pad 7 becomes higher than that of the peripheral portion, so that the attached diseased part can be locally subjected to thermal treatment.

Also, unlike the above treatment, when only electric treatment is performed without heat treatment, the AC adapter can be removed and only electric treatment can be performed using the battery in the treatment device body 9 as a power supply. Such switching of the treatment contents is performed by the treatment switch 11 and the heat switch 10 of the main body 9. Whether the AC adapter or the battery built in the main body 9 is used as the power supply is determined by turning on the heat switch 10, OF
It is switched by F.

Next, the method of using the above-described electrode 8 will be described. The entire surface of the adhesive conductive pad 7 is attached to the affected part of the user. In this state, treatment is performed by operating the treatment device body 9. When the treatment is performed several times, the adhesive conductive pad 7 gradually becomes dirty. Therefore, the adhesive conductive pad 7 is peeled off from the electrode sheet 5 and a new one is stuck so that it can be used again.

As described above, since the wiring of the wire portion 3 of the heating element 2 is densely wired at the central portion and coarsely wired at the peripheral portion, the cross-sectional area of the wire portion 3 of the heating element 2 is Is small and the surrounding area is large, so that in addition to the low frequency treatment, a high temperature can be applied locally, and a local heat treatment, that is, the effect of moxibustion can be obtained.

Since the adhesive conductive pad 7 is detachable from the electrode sheet 5, the adhesive conductive pad 7 that has become brittle or dirty due to aging of the thermal treatment can be easily replaced. Can be.

[0026]

According to the present invention, since the electrode is bent, the low frequency treatment accompanied by heat can be performed in close contact with the affected part of the user, and the treatment effect can be enhanced. In addition, since the pattern is printed while being stretched over the entire surface while the line portion is folded, it is possible to provide an electrode that does not impair the flexibility of the electrode even if a thermal treatment is performed in addition to a normal low frequency treatment. it can. Further, since the adhesive conductive pad which is in contact with the affected part can be easily replaced, the effect such as good usability can be obtained.
