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. As an electrotherapy device that can easily perform this ion osmosis therapy, the present inventors insulate the positive and negative electrodes forming the primary battery with an insulating member, and cover the primary battery except for the electrode surface that is in contact with the skin. A peelable cover sheet in which the gap formed inside the outer packaging material is filled with a fluid therapeutic drug with electrical conductivity, and the gap filled with this drug is adhered to the electrode surface in contact with the skin. A sealed one was previously developed (see Patent Document 1).

  This electrotherapy device does not require a separate power source, and can achieve the effect of ion osmosis by simply applying the outer packaging material covering the battery to the skin, but the therapeutic agent is placed in the gap formed inside the outer packaging material. Since filling is necessary, 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 were also problems.

  For these problems, the present inventors have developed a positive electrode plate that is affixed to the skin contact surface of a medicinal cloth impregnated or coated with a therapeutic agent that contains an ionizing component, and a negative electrode that is in contact with the skin. A space is provided between the plate surfaces of the plate, an electrolytic solution is interposed between the two electrode plates provided with this space, and an outer peripheral portion between the two electrode plates of the battery in which the electrolytic solution is interposed is formed by an insulating annular seal member. A sealed electrotherapy device has been previously proposed (Japanese Patent Application No. 2004-2978).

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

  In the electrotherapy device proposed in Japanese Patent Application No. 2004-2978, a positive electrode plate of a battery is attached to a skin contact surface impregnated or coated with a therapeutic agent for a medicinal cloth, and the negative electrode plate is brought into contact with the skin. As a result, the drug component on the drug surface is ionized and absorbed from the skin, so that sufficient ion osmosis therapy effect is obtained and the function does not deteriorate during storage. Therefore, disassembly and assembly are difficult, and there is a problem that batteries and parts cannot be replaced.

  In addition, the conventional electrotherapy device has a problem that it cannot be used for a medicinal cloth using a therapeutic agent that does not contain an ionizing component.

  Accordingly, an object of the present invention is to provide an electrotherapy device that can be easily disassembled and assembled, and an electrotherapy device that can also be used for a medicinal cloth using a therapeutic agent that does not contain an ionizing component.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show a first embodiment. As shown in FIGS. 1 (a) and 1 (b), this electrotherapy device includes a positive electrode plate 1 formed of a copper plate with gold plating on the outer surface, and a negative electrode plate 2 formed of a titanium plate. A button battery 3, which is a solid battery in which a positive electrode 3 a and a negative electrode 3 b are provided on the opposite side between the electrode plates 1 and 2, which are provided with a gap, is formed between the positive electrode 3 a and the negative electrode 3 b. Are disposed toward the positive electrode plate 1 and the negative electrode plate 2, respectively, and a conductive leaf spring 4 is interposed on the positive electrode 3a side of the button battery 3 to ensure conduction between the two electrode plates 1 and 2. An insulating annular seal member 5 is mounted on the outer peripheral side of the electrode plates 1 and 2.

  The central portions of the electrode plates 1 and 2 bulge outward, and an insulating rubber elastic ring 6 is fitted on the outer periphery of the button battery 3 disposed in the bulged portion. Is sandwiched between the outer peripheries of both electrode plates 1 and 2. Therefore, the button battery 3 does not rattle between the electrode plates 1 and 2, and there is no possibility that the electrode plates 1 and 2 are short-circuited at the outer periphery. The voltage of the button battery 3 is set to 1.5 V or less so as not to cause a burn.

  The annular seal member 5 is formed of silicone rubber which is an elastic body, and a groove 5a for inserting and locking the outer peripheral edges of the two electrode plates 1 and 2 sandwiching the elastic ring 6 is provided on the inner periphery. Therefore, since the annular seal member 5 can be easily attached and detached without a tool, and both the electrode plates 1 and 2, the button battery 3 and the leaf spring 4 are only laminated on the inner peripheral side, this electrotherapy device can be easily used. Disassembly and assembly can be performed, and the button battery 3 and the like can be easily replaced.

In addition, as shown in FIG.2 (b), you may affix a several electrotherapy device to the medicinal cloth 7 at a suitable space | interval as needed.

  FIG. 3 shows a state in which the medicinal cloth 7 with the electrotherapy device applied thereto is applied to the skin A. The medicinal cloth 7 is smoothly placed along the upper surface of the positive electrode plate 1 and the annular seal member 5 mounted on the outer peripheral side 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 so that current flows from the positive electrode plate 1 to the negative electrode plate 2 through the skin contact surface of the medicinal cloth 7 and the skin A, as indicated by arrows in the figure. Then, the component of the medicine 7a applied to the skin contact surface of the medicinal cloth 7 is ionized and absorbed from the skin A into the body. As described above, since the insulation width by the annular portion of the annular seal member 5 that is in contact with the skin A is 3 mm or more, there is no possibility of overcurrent flowing through the skin and causing burns.

  4 and 5 show a second embodiment. As shown in FIGS. 4A and 4B, this electrotherapy device has the same basic configuration as that of the first embodiment, and the positive electrode plate 1 is formed of a titanium plate. The only difference is that the electrode plate 1 is provided with a projecting portion 1a projecting in all directions toward the outer periphery, and the tip of each projecting portion 1a penetrating the annular portion of the annular seal member 5 is connected by the annular portion 1b. Each overhanging portion 1 a is covered with an overhanging portion 5 b provided on the annular seal member 5.

  As shown in FIG. 5, in this embodiment, since the annular portion 1b of the positive electrode plate 1 is brought into contact with the skin A, even if the therapeutic agent 7a of the medicinal cloth 7 does not contain an ionizing component, an electric current is generated. From the annular portion 1b of the positive electrode plate 1 to the negative electrode plate 2 via the skin A, the drug component is absorbed from the skin A into the body. Further, this current flows in a wide range from the annular portion 1b of the positive electrode plate 1 projecting to the outer peripheral side of the annular seal member 5 to the negative electrode plate 2 contacting the skin A on the inner peripheral side of the annular seal member 5. The drug component is absorbed from a wide range of skin A.

  In the second embodiment described above, the battery disposed between the two electrode plates may be a solid battery and an electrolyte solution interposed between the two electrode plates.

  In each of the embodiments described above, the solid battery is a button battery. However, the solid battery is not limited to a button battery, and may be any battery as long as a positive electrode and a negative electrode are provided on opposite sides. If the paper battery developed recently as a solid battery is used, the thickness of the electrotherapy device can be further reduced.

  Moreover, in each embodiment mentioned above, although the spring member which ensures conduction | electrical_connection to both the electrode plates of a solid battery was cut and raised and it was set as the leaf | plate spring which has a nail | claw, this spring member is not limited to the thing of embodiment. Any form can be used. However, in order to reduce the thickness of the electrotherapy device, a flat one such as a leaf spring is preferable.
