Description

Description: FIELD OF APPLICATION OF THE INVENTION The present invention relates to an electrode used in a low frequency treatment device.

BACKGROUND OF THE INVENTION Conventionally, electrodes used in low frequency therapeutic devices include wet electrodes, dry electrodes, gel electrodes and the like. The wet electrode has an advantage that it has low electric resistance when energized and is unlikely to cause dermatitis, but it has the inconvenience that it must absorb water each time it is used. Further, the dry type electrode is convenient because it does not require water absorption at the time of use, but has a high electric contact resistance, so that there is a problem in that it causes pain and discomfort when energized, and easily causes dermatitis. Further, the gel electrode has problems such as dermatitis, hygiene, and adhesive strength during repeated use.

Another treatment method using a low-frequency treatment device is an iontophoresis method, but each of the above-mentioned electrodes has advantages and disadvantages when performing this treatment method. That is, in the iontophoretic method, the purpose is to introduce the ionized drug in the aqueous solution into the human body by passing an electric current, but in the case of a wet electrode, cleaning after use is complicated when the drug solution is included, There was a problem above. Further, the dry electrode cannot sufficiently contain the chemical liquid, and it is difficult to use the chemical liquid for the gel and the electrode.

[Object of the Invention] The present invention has been made by paying attention to such a conventional problem, and fixes a water absorbing material to an opening provided at one end of a container filled with an aqueous solution and energizes the water absorbing material. To provide a water-absorbing material by providing a bellows or the like at the other end of the container and pushing the bellows to drop it, or by utilizing the strain of the other end and the container by pressing. Taking advantage of the wet electrode by absorbing liquid in
Furthermore, it can be greatly improved by eliminating the inconvenience of water absorption after each use, and the container can be made into a cartridge type and made disposable, so that energization treatment by a low frequency treatment device can be made simple and safe. It is an object of the present invention to provide an electrode of a low-frequency treatment device that can be performed and is optimal for treatment by an iontophoresis method.

Embodiments of the Invention Embodiments of the present invention will be described below in detail based on the embodiments shown in the drawings.

Reference numeral 1 denotes a casing of an electrode, which is formed in an elongated shape so that a user can easily hold it, and an electrode main body 2 is exposed at one end of the casing 1 in an exposed state. Has been formed. This electrode body 2

Further, the absorbent material 4 is It is located so as to be in contact with the liquid injection port 6 provided in the energization liquid container 5 housed in the casing 1. This energized liquid container is formed of, for example, a resin material such as polyethylene, and a bellows portion 7 is formed on a part of the container 5, and by pressing the bellows portion 7, the energized liquid container 5 is placed inside the energized liquid container 5. The filled energizing liquid is
It can be pressed from the liquid injection port 6 to permeate the absorbent material 4. Reference numeral 8 denotes a push button that is held by the casing 1 and can push the bellows portion 7 of the container 5, and 7 is a printed circuit board that constitutes an oscillator. Is connected to the absorber 4 and the positive electrode of the oscillator is connected to the conductive rubber 3 via the electrode plate 11. 12 is a power supply (battery) stored in the casing, 13 is a start switch,
Reference numeral 14 is an output adjustment dial, 15 is a frequency adjustment slide knob, and 16 is an electrode protection cap that is attached to the electrode body 2 when the electrode is not used.

The structure of the present embodiment has been described above. Next, its operation will be described. Since a low frequency is applied between the conductive rubber 3 and the absorber 4 when the switch is turned on during use, its conductivity is reduced. As is well known, when the rubber 3 and the absorbent 4 are brought into contact with the skin, low-frequency energization is performed and treatment is performed, but it is necessary to moisten the absorbent 4 when energizing the human body. Therefore, in order to moisten the absorbent material 4, when the push button 8 is pressed, the bellows 7 of the container 5 is pressed and the liquid in the container 5 is poured out from the liquid injection port 6 and permeates the absorbent material 4. Therefore, the absorbent 4 can be humidified very easily.
The liquid in the container 5 may be saline, but the ionized drug can be introduced into the human body by mixing the ionized drug. Further, by making the container 5 a cartridge type, it becomes easy to replace it with a new liquid filling container when the liquid is consumed.

In the above embodiment, the oscillator and its power source were built in the casing 1. However, the oscillator and the power source are installed outside the casing 1, and a cord is used from this external oscillator to energize the electrode body 2 described above. May be. Further, in the above embodiment, the absorber 4 located in the central portion of the electrode body 2 is
Although the liquid in the container 5 is made to permeate, the present invention is not limited to this, and the liquid from the container 5 may be made to permeate the absorbent, for example, by using the annular conductive rubber 3 as the absorbent.

As described above, in the present embodiment, in the electrode for a low-frequency treatment device in which the casing 1 is provided with the wet electrode body, the inside of the casing is the liquid injection port 6 that comes into contact with the wet electrode body, and the liquid injection port 6 Since the energizing liquid container 5 formed by forming the bellows 7 for pouring out is built in so that it can be taken in and out, by appropriately pushing the bellows 7 of the energizing liquid container 5 filled with the energizing liquid. It is extremely easy to permeate the current-carrying liquid into the absorbent material (electrode body) through the liquid injection port 6, and it is possible to greatly reduce the time and effort of humidifying and applying an ionizing agent to the wet electrode, which has been conventionally inconvenient. is there. Further, by making the energizing liquid container 5 a cartridge type, it is possible to dispose the container, and there is also an effect that hygienic management is performed particularly when an ionized drug is used.
