Description

[Detailed Description of the Invention] (a) Industrial Application The present invention relates to an electric therapy device that uses a sheet-shaped battery attached to a predetermined location on the human body to achieve a therapeutic effect such as relieving stiff shoulders. Specifically, the present invention relates to the structure of an electric treatment device that eliminates self-discharge and can be stored for a long period of time.

(b) Conventional technology Conventionally, as this type of electric treatment device, Japanese Patent Application Laid-Open No. 51-1296
There is one shown in Japanese Patent Publication No. 2 (hereinafter referred to as the former) and one shown in Japanese Patent Application Laid-open No. 194752/1983 (hereinafter referred to as the latter).

In the former case, the positive electrode is a silver-impregnated porous nylon mesh, the negative electrode is a zinc foil, and an electrolyte is interposed between them to form a sheet battery, and a conductive strip is provided around the positive electrode sheet. The stop is constructed by conducting electricity from the negative electrode sheet through a conductor with a current adjustment circuit interposed therebetween.

When the sheet-shaped battery is used, the electrolyte (electrolyte) is oozed out by tearing the cell to generate a voltage, and the battery is fixed to the affected area using an adhesive.

In the latter case, a sheet material containing carbon fiber or fine carbon particles at a high density is used as the positive electrode, a metal foil such as aluminum or zinc is used as the negative electrode, and office glue interposed between the electrodes is used as the electrolyte. As such, a sheet battery is constructed.

Then, the sheet-shaped battery is used by being attached to the skin with an adhesive film made of a plastic film or the like, and at this time, moisture from the skin accumulates on the inner surface of the adhesive film, and an electric circuit is formed through the moisture.

(T→ Problem to be solved by the invention) By the way, the former method does not include the near (positive electrode) sheet, far (negative electrode) sheet, electrolyte, conductive strip, current adjustment circuit, insulating tape, etc. that constitute the battery. Furthermore, when using it, it is necessary to break the medicinal pin and ooze out the electrolyte, making the method of use cumbersome and making it difficult to use in general households. Relatively simple to treat stiff shoulders, etc. (This is not suitable as a treatment tool.

In addition, in the latter case, the positive electrode sheet and the negative electrode sheet are in contact with each other with an adhesive interposed therebetween, and self-discharge occurs relatively early. Therefore, it is distributed from the manufacturer through wholesalers, pharmacies, etc.
This type of treatment device takes a relatively long time to use,
In actual use, self-discharge occurs and there is a risk that no therapeutic effect can be expected.

Therefore, the present invention maintains the separator in a dry state to insulate the positive and negative electrodes during storage, prevents self-discharge, and automatically adds moisture during use to form a battery, which has a simple structure. However, the purpose is to provide an electric treatment device that can be stored for a long period of time.

B) Means for solving the problem The electric treatment device S according to the present invention has been developed in view of the above-mentioned circumstances, and for example, as shown with reference to FIG. , a metal foil 2 constituting a negative electrode, a separator 3 interposed between the depolarization mixture 1 and the metal foil 2, containing an electrolyte and a liquid retaining agent, and having hygroscopic properties, and the depolarization mixture 1, Adhesive member 5 that can cover the sheet-like material made of metal foil 2 and separator 3 and stick to the skin
It consists of and.

Then, as shown in detail in FIG. 2, for example, the metal foil 2, the separator 3, and the depolarization mixture 1 are superposed on each other so that one side of each of them is exposed, and the container and the separator 3 are
It is characterized in that it is in a dry state under normal conditions, and moisture is automatically applied from its exposed surface upon use.

(e) Function Based on the above configuration, during storage, the separator 3 is kept in a dry state and acts as an insulator. Therefore, depolarization mixture 1
The metal foil and the battery are insulated with an insulator, so they do not form a battery and no natural discharge occurs.

Furthermore, when the electric treatment device S is attached to the affected area using the adhesive member 5, moisture emitted from the skin, for example, is exposed and absorbed by the hygroscopic separator 3, and the electrolyte contained in the separator 3 is absorbed. The substance is melted to form an electrolytic solution, and the WsM solution is held within the separator 3 by a liquid retaining agent. As a result, a battery is formed between the depolarizing mixture 1 and the metal foil 2, and since both the depolarizing mixture 1 and the metal foil 2 are in contact with the skin (directly or through gauze, etc.), , to treat stiff shoulders, etc. by passing a small electric current through the affected area.

(F) Embodiments Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the electric treatment device S is made of a flexible sheet, and includes a depolarization mixture 1, a metal foil 2 and a separator 3 constituting the negative electrode, and an adhesive member 5. Become.

Depolarization mixture 1 is a mixture of manganese dioxide, carbon powder (acetylene black or graphite), and ammonium chloride in a predetermined ratio to a sheet material such as Japanese paper, pulp, chemical fiber, or synthetic fiber, and is used as a binder. It is formed by adhesion in water or by impregnation in water in the presence of an adsorbent.

Further, the metal 7r12 is made of aluminum foil or zinc foil having a predetermined thickness.

Furthermore, the separator 3 is made of a hygroscopic porous sheet material such as paper, fiber, felt, or polypropylene nonwoven fabric, and the sheet material is coated with ammonium chloride and zinc chloride, a cotton-like valve constituting a liquid retaining agent, and a high Apply a mixture of a molecular absorber or a sizing agent such as cornstarch, or immerse the sheet material in the presence of the sizing agent in an electrolytic solution containing ammonium chloride and zinc chloride as main components, and then Dry and form.

The adhesive member 5 is made of a sheet material in which an adhesive is coated on one side of a plastic film that does not permeate moisture or a fiber and porous plastic film that permeates moisture.

Then, a sheet-shaped depolarization mixture 1, gold FEE foil 2,
The separator 3 and adhesive member 5 are cut to a predetermined size.

That is, the adhesive member 5 is placed in the largest area, followed by the depolarization mixture 1, and then the separator 3 and the metal foil 2 in decreasing order.
cut. Then, the depolarization mixture 1 is placed on the adhesive member 5,
Further, a separator 3 is placed on top of the separator 3, and a metal foil 2 is placed on top of the separator 3, and these are pasted so that they are all exposed on one side.

The electric therapy device S is molded in the above manner, but after molding, it is hermetically packaged with a heat seal film 6 or aluminum foil, or stored together with a moisture absorbent to maintain a predetermined dry state. Be it.

Since this electrotherapy device S has the above-mentioned configuration, the separator 3 is in a dry state during storage, and therefore acts as an insulator to prevent damage between the X-pole mixture 1 and the metal foil 2. is maintained in a substantially insulated state. As a result, the electric treatment tool S does not constitute a battery, and even if a slight voltage is generated due to water contained in the paste, the voltage is in units of 1/10 volt and will not spontaneously discharge.

Then, in use, the package 6 is torn, the electric treatment tool S is taken out, and the treatment tool S is adhered to the affected area using the adhesive member 5.

Then, the water-impermeable adhesive member 5 or separator 3 and depolarization mixture 1 prevent the evaporation of moisture emitted from the skin, and the moisture absorbs moisture from the exposed area that is in contact with the skin. It is absorbed into the separator 3 that has The moisture melts the electrolyte in the separator 3 to generate an electrolyte,
Moreover, the electrolytic solution is held in a gel state by a liquid retaining agent.

This constitutes a battery, in which a weak current is passed between the depolarizing mixture 1 and the metal foil 2 that are in contact with the skin, thereby treating unpleasant symptoms such as stiff shoulders. Therefore, it is particularly effective when used when the body's metabolism is active, such as after taking a bath.

Furthermore, when a weak electric current is passed through the skin, the area becomes warm like a warm compress, and moisture evaporates from the body.
This ensures the electrolytic solution generation action in the separator 3 described above.

In the above embodiment, the depolarization mixture 1, the metal foil 2, and the separator 3 were brought into direct contact with the skin. You can.

In addition, the separator 3 contains a small amount of moisture absorbent such as sodium alginate or potassium carbonate, and when the package 6 is torn and exposed to the air, the exposed state is maintained for a predetermined period of time by blowing, etc. The water may be taken into the separator 3 by the action of the above-mentioned moisture absorbent to assist in constructing the above-mentioned battery, and sweating due to the above-mentioned warm compress action may be expected from the beginning of use.

In addition, the shape of the electric treatment device S is not limited to a rectangle as shown in FIG. 2, but may be any shape such as a circle or a square. The relationship between the depolarization mixture 1 and the metal foil 2 may be reversed, and a small area of the depolarization mixture may be placed in the separator 3. The metal foil may be of other materials.

(G) As described in detail, the present invention has an extremely simple structure consisting of the depolarization mixture 1, metal foil 2, separator 3, and adhesive member 5, and therefore can be manufactured at low cost and is easy to use. Although it can be used as a disposable electric treatment device, during storage, the separator 3 acts as an insulator, preventing self-discharge of the battery and allowing it to be stored for a long period of time. Moisture is automatically added to the separator 3 to form a battery, and the affected area can be reliably treated with a weak current.
