Description

  The present invention relates to an electrotherapy device for iontophoresis.

  As a treatment method for neuralgia, stiff shoulders, etc., ion osmosis therapy is known in which drug components are ionized and absorbed from the skin into the body. The present inventors have previously developed a device using a small primary battery as an electrotherapy device that can easily perform this ion osmosis therapy (see Patent Document 1). In this electrotherapy device, the positive and negative electrodes forming the primary battery are insulated by an insulating member, and conductivity is provided in the gap formed inside the outer packaging material covering the primary battery except for the electrode surface that is in contact with the skin. The added fluid therapeutic drug is filled, and the gap filled with this drug is sealed with a peelable cover sheet adhered to the electrode surface in contact with the skin. When using this electrotherapy device, the electrode surface from which the cover sheet is peeled is brought into contact with the skin, and the drug is ionized and absorbed from the skin by the electromotive force of the primary battery.

Japanese Examined Patent Publication No. 3-69545 (page 2-3, Fig. 1-3)

  The conventional battery-type electrotherapy device described above does not require a separate power source, and the effect of ion osmosis can be achieved by simply applying the outer packaging material covering the battery to the skin, but it is formed inside the outer packaging material. Since it is necessary to fill the gap with a therapeutic agent, there is a problem that the structure is complicated and time-consuming to manufacture. In addition, since the filled chemical is stored in contact with one electrode (positive electrode) before use, the electromotive force of the battery decreases during storage, or the metal piece used for the positive electrode corrodes with the chemical. There are also problems.

  Accordingly, an object of the present invention is to provide a battery-type electrotherapy device that has a simple structure and does not deteriorate in function during storage.

  In order to solve the above-described problems, the present invention provides a positive electrode plate that is attached to a drug surface of a skin patch that is impregnated or coated with a therapeutic drug that contains an ionizing component, and a negative electrode that is in contact with the skin. An interval is provided between the plate surfaces of the electrode plate, an electrolyte is interposed between the electrode plates having the interval, and an outer peripheral portion between the electrode plates of the battery including the electrolyte is sealed with an insulating ring The structure sealed with a member was adopted.

  The inventors of the present invention have conducted research on battery-type electrotherapy devices in order to solve the conventional problems, and as a result, the battery surface on the drug surface impregnated or coated with a therapeutic agent for a skin patch such as a compress. It was confirmed by trial that the drug component on the drug surface was ionized and absorbed from the skin, and a sufficient ion osmosis therapy effect was obtained simply by applying the positive electrode plate and contacting the negative electrode plate with the skin. . Therefore, a treatment including a component that ionizes the positive electrode plate during use is prepared by using a single battery in which an electrolyte is interposed between positive and negative electrode plates that are spaced apart and the outer periphery is sealed with an insulating annular seal member. By adopting a structure in which the medical agent is impregnated or applied to the surface of the medicinal cloth impregnated or applied, the function is not deteriorated during storage with a simple structure.

  By impregnating and interposing the electrolytic solution in a fibrous or porous medium, the electrolytic solution can be stably interposed between the positive and negative electrode plates. As the fibrous or porous medium, gauze, cotton, sponge, or the like can be used.

  The battery life can be extended by expanding at least the central part of the positive electrode plate of both the electrode plates outwardly and widening the distance between the plate surfaces on which the electrolytic solution is interposed.

  By projecting the annular seal member from the outer peripheries of the two electrode plates and covering at least the outer peripheral end surface of the negative electrode plate, an electric circuit is formed which conducts from the positive electrode plate to the negative electrode plate without passing through the skin. And ionized drug components can be efficiently absorbed from the skin.

  By forming a corrosion-resistant conductive film on the surface of the positive electrode plate attached to the drug surface of the medicinal cloth, corrosion of the positive electrode plate due to the drug on the drug surface can be prevented.

  By setting the thickness of the positive and negative electrode plates to 0.3 mm or less, the electrotherapy device can be made extremely thin and flat so that it does not rise from the skin, and the uncomfortable feeling during use can be eliminated.

  The voltage of the battery is desirably 1.0 V or less. This is because if the battery voltage exceeds 1.0 V, the skin may be burned.

  The electrotherapy device of the present invention provides a single battery in which an electrolytic solution is interposed between positive and negative electrode plates with a gap and the outer periphery thereof is sealed with an insulating annular seal member. Since it is configured to be affixed to the drug surface of a medicinal cloth impregnated or coated with a therapeutic drug containing an ionizing component, it can be manufactured at a low cost with a simple structure, and there is no risk of deterioration of its function during storage.

  By impregnating and interposing the electrolytic solution in a fibrous or porous medium, the electrolytic solution can be stably interposed between the positive and negative electrode plates.

  The battery life can be extended by expanding at least the central part of the positive electrode plate of both the electrode plates outwardly and widening the interval between the plate surfaces through which the electrolytic solution is interposed.

  By projecting the annular seal member from the outer peripheries of the two electrode plates and covering at least the outer peripheral end surfaces of the negative electrode plates, an electric circuit is formed which conducts from the positive electrode plate to the negative electrode plate without passing through the skin. The ionized therapeutic agent can be efficiently absorbed from the skin.

  By forming a corrosion-resistant conductive film on the surface of the positive electrode plate attached to the drug surface of the medicinal cloth, corrosion of the positive electrode plate due to the drug on the drug surface can be prevented.

  By setting the thickness of the positive and negative electrode plates to 0.3 mm or less, the electrotherapy device can be made extremely thin and flat so as not to rise from the skin, and discomfort during use can be eliminated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show a first embodiment. As shown in FIG. 1, this electrotherapy device has an interval between plate surfaces of a positive electrode plate 1 formed of a copper plate and a negative electrode plate 2 formed of an aluminum plate, and this interval is provided. The electrolyte 3a impregnated in the sponge 3 is interposed between the electrode plates 1 and 2 and the outer periphery thereof is sealed with an insulating annular seal member 4. A voltage of about 4V is generated. Each of the electrode plates 1 and 2 is a disc having a thickness of 0.2 mm, and a conductive coating 5 is formed on the surface of the positive electrode plate 1 with aluminum having corrosion resistance.

  The annular seal member 4 is formed by a ring portion 4 a that keeps a distance between the electrode plates 1 and 2, and an overhanging portion 4 b that protrudes from the outer periphery of the electrode plates 1 and 2. This overhang | projection part 4b covers the outer peripheral end surface of both the electrode plates 1 and 2, the surface applied to the chemical | medical agent surface of the medicinal cloth 6 mentioned later is formed in a circular arc surface, and the surface applied to skin is formed in the plane. The overhanging portion 4 b may cover only the outer peripheral end surface of the negative electrode plate 2.

  FIG. 2 shows a state where the electrotherapy device is applied to the drug surface of the medicinal cloth 6 to which the therapeutic drug 6a containing the component to be ionized is applied. In the electrotherapy device, the positive electrode plate 1 is affixed to the drug surface of the medicinal cloth 6 so that the negative electrode plate 2 applied to the skin is exposed. If necessary, a plurality of electrotherapy devices may be attached to the medicinal cloth 6 at appropriate intervals.

  FIG. 3 shows a state in which the medicinal cloth 6 to which the electrotherapy device is attached is applied to the skin A. The medicinal cloth 6 is smoothly placed along the upper surface of the positive electrode plate 1 and the annular seal member 4 protruding on the outer periphery thereof to cover the skin A, and the negative electrode plate 2 is in contact with the skin A. The electric circuit formed by the electrotherapy device is formed such that electricity flows from the positive electrode plate 1 to the negative electrode plate 2 via the drug surface of the medicinal cloth 6 and the skin A, as indicated by arrows in the figure. The component of the medicine 6a applied to the medicine surface of the medicinal cloth 6 is ionized and absorbed from the skin A into the body.

  FIG. 4 shows a second embodiment. The electrotherapy device has the same basic configuration as that of the first embodiment, and is formed such that the central portion of the positive electrode plate 1 bulges outward, and the electrolytic solution impregnated in the sponge 3 The only difference is that the distance between the electrode plates 1 and 2 interposing 3a is wide. Therefore, in this embodiment, the life of the battery can be extended. Note that the negative electrode plate 2 may also be formed so that the central portion bulges outward.

  In each of the above-described embodiments, the copper plate and the aluminum plate are used as the positive and negative electrode plates. However, these electrode plates only need to form a primary battery, and other materials can also be used. In addition, a conductive coating having corrosion resistance was formed on the surface of the positive electrode plate. However, the electrotherapy device according to the present invention is used only for trial use because the positive electrode plate comes into contact with the drug on the medicinal cloth only during use. It can be omitted depending on the period and type of medicine.
