Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an electrotherapy device, particularly an electrotherapy device that performs iontophoresis.

[Conventional technology]

There is an electric therapy device (Utility Model Publication No. 14343, 1983) that performs iontophoresis to treat neuralgia, stiff shoulders, headaches, muscle pain, sprains, and the like.

This electric therapy device consists of an electric therapy device main body equipped with an anode terminal and a cathode terminal, and a conductor connected to the tip of a conducting wire connected to the anode terminal and cathode terminal, respectively, and both conductors are equipped with electrodes. A holder is fixed to this electrode, and a conductive liquid-impregnated piece is fitted into the holder, and the conductive liquid-impregnated piece on the affected area side is also impregnated with a therapeutic drug solution.

Then, one conductor is applied to the affected treatment point and the other conductor is applied to a symmetrical position of the affected treatment point and electricity is applied, whereby the medicinal liquid components are ionized and absorbed into the body through the subcutaneous tissue, resulting in excellent therapeutic effects.

[Problem that the invention seeks to solve]

The conventional electric therapy device described above consists of a power supply, the main body of the therapy device, and both Yin and Yang conductors, which makes the device large and requires the hands of the practitioner. is bound.

On the other hand, an electric therapy device with a built-in battery that could be used by attaching it to the human skin was developed in 1983-
It is described in Publication No. 130054 and Japanese Unexamined Patent Publication No. 60-60860.

However, these electric therapy devices have an adhesive part for the therapeutic drug (Kan-doko) in the center and a conductive adhesive member (Kan-doko) to adhere to the skin on the outer periphery, so it is difficult to attach the drug. The size and shape of the electrotherapeutic device are limited by the size of the conductive adhesive member, and if an attempt is made to treat a wider skin area, the overall shape of the electrotherapy device becomes larger.

Additionally, because the adhesive part of the drug is on the inside, side effects or burns caused by the drug may be difficult to detect immediately.

Furthermore, since the treatment device is equipped with conductive wires and conductive members for current dispersion, the structure becomes complicated, and the flexibility of the entire treatment device is lost due to the conductive members and conductive cover. It has the disadvantage that it bends and makes it difficult for the skin to move when it is applied.

Therefore, this invention provides an electric therapy device that can be directly attached to the skin of the human body, has a compact shape, allows the shape and size of the adhesive part of the therapeutic drug to be freely designed, and has excellent flexibility. It is intended to.

[Means for solving problems]

In order to solve the above problems, this invention
One is to provide one electrode on one side of a small primary battery and the other electrode on the other side, and connect the outer surface of the one electrode, the circumferential side of the battery, and the periphery of the other electrode with a required gap. the other electrode is insulated from the one electrode and the gap with a layer of electrically insulating material, and the gap is filled with a fluid therapeutic agent having added electrical conductivity; The electrical treatment device is made by sealing the circumferentially open portion of the gap with the outer packaging material and a removable sheet adhered to the other electrode.

Another aspect of the present invention is to arrange a low frequency generator on the side of a small primary battery, using the battery as a power source and connected to the input side, and on the top surface of the battery and the low frequency generator, one side is arranged. The other electrode is disposed on the lower surface of the electrode, the battery and the low frequency generator, and the output side terminals of the low frequency generator are connected to these electrodes, respectively, and the outer surface of the one electrode and the battery and the low frequency generator are connected to each other.

The electrotherapy device is made by filling the gap with a peripheral open portion of the gap and sealing it with a peelable sheet adhered to the outer packaging material and the other electrode.

[Effect]

When using the electric therapy device of this invention,
After peeling off the sheet that closes the opening on the circumferential side of the gap filled with the therapeutic agent, the other exposed electrode is soaked in an electrifying liquid and attached to the treatment point of the affected area, and By fixing the treatment device to the skin with the periphery of the outer packaging material or a bandage, the current from the primary battery flows between the two electrodes, creating an electrical circuit under the skin at the treatment point of the affected area, and reducing the fluidity of one electrode. The therapeutic agent is ionized and penetrates and absorbed into the treatment point by the electric current of the electrical circuit formed.

Another electric therapy device of the present invention, in which a small low-frequency generator is connected to the side of a primary battery, is attached to the treatment point of the affected area to create an electric circuit under the skin, like the electric therapy device described above. When the therapeutic drug is ionized and absorbed subcutaneously, the low-frequency generator is activated and a low-frequency pulse is applied to the affected treatment point, stimulating the affected area and promoting blood flow, as well as absorbing the therapeutic drug. hasten the
