BEST MODE FOR CARRYING OUT THE INVENTION

[0051] Examples of the present invention shall be described below.

[0052] In the biogalvanic battery therapeutic appliances of these examples, the thickness of the printed carbon-layer film is 10 .Math.m as measured in cross section, the resistance value (top surface resistance value) of the printed carbon-layer film is 40 Ω , the thickness of the printed zinc-layer film is 20 .Math.m as measured in cross section, and the weight or weight ratio of zinc in the coating of zinc-blended silicon is calculated to be 1.349 g of zinc and 0.193 g of Si ink.

First Example

[0053] FIG. 3 is a schematic explanatory drawing of the steps of manufacturing a sheet-form biogalvanic battery therapeutic appliance, which is the first example.

[0054] First, a carbon silicon sheet 23 (electroconductive member) is prepared as shown in the uppermost diagram in FIG. 3.

[0055] Next, zinc silicon 21 (negative electrode constituent member) is printed from above the carbon-silicon sheet 23 on the surface side that will come into contact with the skin, as shown in the second diagram from the top of FIG. 3 (the top surface side of this diagram is the surface side that will come into contact with the skin). In this example, the carbon silicon sheet 23 (electroconductive member) is otherwise left exposed.

[0056] Next, regular silicon 24 (insulating layer) is applied over and thereby printed on the entire surface of the carbon silicon sheet 23 (electroconductive member) that is opposite to the surface that will come into contact with the skin, as shown in the third diagram from the top of FIG. 3 (the top surface side of this diagram is the surface side opposite to the surface that will come into contact with the skin).

[0057] Then, noble metal silicon 22 (positive electrode constituent member) is applied over and thereby printed on the surface (the upper side of the second diagram in FIG. 3) where the carbon silicon sheet 23 (electroconductive member) is exposed, as shown in the lowest diagram of FIG. 3 (the top surface side of this diagram is the surface side that will come into contact with the skin).

[0058] In the biogalvanic battery therapeutic appliance thus configured, the surface on which the zinc silicon 21 (negative electrode constituent member) and the noble metal silicon 22 (positive electrode constituent member) are formed (the top surface side in the lowest diagram in FIG. 3) is brought into contact with the skin, so that ions from the negative electrode constituent substance efficiently flow to the positive electrode constituent member through the low-electrical-resistance carbon silicon sheet layer (electroconductive member) on the surface opposite to the surface that will come into contact with the skin). As a result, current effectively flows to the skin with which the positive electrode constituent substance and the negative electrode constituent substance of the biogalvanic battery therapeutic appliance come into contact, and the purpose of the biogalvanic battery therapeutic appliance is efficiently achieved.

[0059] In this example, the zinc silicon 21 (negative electrode constituent member) and the noble metal silicon 22 (positive electrode constituent member) are in direct contact with each other, but because the zinc silicon 21 (negative electrode constituent member) has a high electrical resistance value, in essence, ions from the negative electrode constituent substance flow to the positive electrode constituent member 22 through the low-electrical-resistance carbon silicon sheet 23 (electroconductive member) on the surface opposite to the surface that comes into contact with the skin.

Second Example

[0060] FIG. 4A shows an example of a substantially L-shaped biogalvanic battery therapeutic appliance comprising a base piece 41 and a rising piece 42 rising from one end of the base piece. This biogalvanic battery therapeutic appliance is effective for the face and especially, inter alia, the outer corners of the eyes where there is little muscle movement, and the front surface side in the diagram shows the skin-contacting surface. This biogalvanic battery therapeutic appliance comprises the wide base piece 41 and the narrow rising piece 42 rising from one end of the base piece 41. In FIG. 4, reference symbol 31 indicates a negative electrode constituent member provided to the base piece 41, reference symbol 32 indicates a button-form positive electrode constituent member provided to the tip of the rising piece 42, and reference symbol 35 indicates an insulating layer (first insulating layer).

[0061] FIG. 5 shows an exploded perspective view of the biogalvanic battery therapeutic appliance of FIG. 4A. In FIG. 5, reference symbol 33 indicates a substantially L-shaped electroconductive member, reference symbol 33a indicates a base piece of the electroconductive member, and reference symbol 33b indicates a rising piece of the electroconductive member. The left side of the electroconductive member 33 in FIG. 5 (the top surface side opposite to the skin-contacting surface in the biogalvanic battery therapeutic appliance) is provided with a substantially L-shaped second insulating layer 34 (base piece 34a, rising piece 34b) that covers the electroconductive member 33.

[0062] The right side of the electroconductive member 33 in FIG. 5 (the skin-contacting surface side in the biogalvanic battery therapeutic appliance) is provided with the first insulating layer 35, and the rising piece 33b of the substantially L-shaped electroconductive member 33 is covered by the first insulating layer 35. However, the first insulating layer 35 is not covered by the thick part of the rising piece 33b of the electroconductive member 33 or by the tip of the thick part (the location where the positive electrode constituent member 32 is attached in this example).

[0063] Furthermore, the negative electrode constituent member 31 is provided on the right side of the electroconductive member 33 in FIG. 5 (the skin-contacting surface side in the biogalvanic battery therapeutic appliance), and the negative electrode constituent member 31 covers the skin-contacting surface side of the base piece 33a of the substantially L-shaped electroconductive member 33.

[0064] In addition, the button-form positive electrode constituent member 32 is provided at the tip of the rising piece 33b of the electroconductive member 33 (see FIG. 4A).

[0065] In the biogalvanic battery therapeutic appliance thus configured, when the negative electrode constituent member 31 and the positive electrode constituent member 32 are brought into contact with the covering, electrons generated from the ionized negative electrode component of the negative electrode constituent member 31 pass through the electroconductive member 33 to enter the positive electrode constituent member 32, and the desired current passes through the skin. Therefore, even if the electrical resistance value of the negative electrode constituent member 31 is high, the current flows through the thin negative electrode constituent member 31 from the electroconductive member 33 to the positive electrode constituent member 32, and thus the problem of the negative electrode constituent member 31 having a high electrical resistance value of can be solved and current can be caused to flow efficiently.

Third Example

[0066] FIG. 4B shows another example of a substantially L-shaped biogalvanic battery therapeutic appliance, and shows a biogalvanic battery therapeutic appliance that is effective for the face and especially, inter alia, the smile lines where there is much muscle movement.

[0067] The basic configuration and operative effects of this biogalvanic battery therapeutic appliance are the same as those of the biogalvanic battery therapeutic appliance of FIGS. 4A and 5, but the difference is that a spring part 43 is formed partway along the rising piece 42, enabling the rising piece 42 to elastically deform following muscle movement. Due to the appliance being thus configured, even if the corners of the mouth are moved, the biogalvanic battery therapeutic appliance elastically deforms correspondingly, and as a result, the function of the invention can be effectively maintained.

[0068] FIG. 4C is a schematic view of an area through which the current flowing to the skin flows when the substantially L-shaped biogalvanic battery therapeutic appliance is brought into contact with the skin. The advantage of the biogalvanic battery therapeutic appliance being L-shaped, as can be seen in FIG. 4C, is that it is possible to form a wide-range ion current band surrounded by the L-shaped biogalvanic battery therapeutic appliance.

Fourth Example

[0069] FIG. 6 is an explanatory drawing of the steps of manufacturing an H-shaped biogalvanic battery therapeutic appliance.

[0070] The following is described in the order of the manufacturing steps. An electroconductive member and H-shaped electroconductive rubber 40 constituting a positive electrode constituent member are prepared.

[0071] Next, a negative electrode constituent member 41 is mounted on one piece of the H-shaped electroconductive rubber 40 (rising piece on the left side of the diagram).

[0072] Next, an insulating layer 42 is mounted on the lateral piece of the H-shaped electroconductive rubber 40.

[0073] Then, an insulating layer 42 is additionally mounted on the other piece of the H-shaped electroconductive rubber 40 (rising piece on the right side of the diagram), elsewhere beside the locations of the electroconductive rubber 40 that are to come into contact with the skin and function as a positive electrode constituent member 43 (the two circular areas in the diagram).

[0074] Through these steps, an H-shaped biogalvanic battery therapeutic appliance according to the present invention is obtained.

[0075] In this biogalvanic battery therapeutic appliance, the near side of the plane of the diagram is the surface that comes into contact with the skin, and the location of the electroconductive rubber 40 covered by the insulating layer 42 and the positive electrode constituent member 43 functions as an electroconductive member, and the two circular areas not covered by the insulating layer 42 function as the positive electrode constituent member 43.

[0076] In FIG. 6, the reference numerals in parentheses indicate the reference numerals of the members on the far side of the plane of the diagram.

Fifth Example

[0077] FIG. 7 is an explanatory drawing of the steps of manufacturing a disc-shaped biogalvanic battery therapeutic appliance.

[0078] The following is described in the order of the manufacturing steps. Circular electroconductive rubber 50 to constitute an electroconductive member and a positive electrode constituent member is prepared.

[0079] Next, a negative electrode constituent member 51 is mounted in the center of the electroconductive rubber 50.

[0080] Next, an insulating layer 52 is mounted on the outer periphery of the negative electrode constituent member 51.

[0081] Then, where the electroconductive rubber 50 is exposed, an insulating layer 52 is additionally mounted on the outer periphery of the insulating layer 52 elsewhere beside locations where the electroconductive rubber 50 is to come into contact with the skin and function as a positive electrode constituent member 53 (the four circular areas in the drawing).

[0082] Through these steps, a disc-shaped biogalvanic battery therapeutic appliance according to the present invention is obtained.

[0083] In this biogalvanic battery therapeutic appliance, the near side of the plane of the diagram is the surface that comes into contact with the skin, and of the electroconductive rubber 50, the location covered by the insulating layer 52 and the positive electrode constituent member 53 functions as an electroconductive member, and the four circular areas not covered by the insulating layer 52 function as the positive electrode constituent member 43.

[0084] In FIG. 6, the reference numerals in parentheses indicate the reference numerals of the members on the far side of the plane of the diagram.

[0085] In the examples described above, flat-plate-form, substantially L-shaped, H-shaped, and disc-shaped biogalvanic battery therapeutic appliances were described, but the present invention is not specified to biogalvanic battery therapeutic appliances of these shapes; the present invention includes biogalvanic battery therapeutic appliances of various shapes depending on, inter alia, the intended use and the location of application.

[0086] The negative electrode constituent member has a standard unipolar potential lower than that of the positive electrode component of the positive electrode constituent member, but metallic zinc is particularly suitable as the negative electrode component.

[0087] In addition, the positive electrode component constituting the positive electrode constituent member may be a metal having an electrode potential higher than that of the negative electrode component; for example, the positive electrode component may be gold (Au), silver (Ag), a platinum group, alloy thereof, etc. There are no particular limitations as to the grain size of the noble metal fine grains, but from the viewpoint of constituting numerous biogalvanic battery units, a grain size of finer grains is preferred, while from the viewpoint of manufacturing, coarse grains are easier to handle. If a compromise is made between these two viewpoints, it is possible to use noble metal fine grains having, for example, an average grain size of 1 nm to 50 .Math.m, an average grain size of 20 nm to 15 .Math.m, an average grain size of 10 to 15 .Math.m, an average grain size of 20 to 40 nm, etc. However, fine grains of such description are not provided by way of limitation on the present invention.

[0088] In the above examples, carbon is given as an example of an electroconductive member, but examples of materials other than carbon include graphite, salt contents, electroconductive polymer materials or electroconductive polymers, etc. It is suitable to use a gel-form electroconductive polymer because such a polymer inherently has an adhesive effect and it is therefore not necessary to blend a binder, an adhesive, etc., therewith. Examples of typical substances for electroconductive polymer materials include polyacetylene, polyaniline, poly(p-phenylene vinylene), polypyrrole, polythiophene, polyaniline, poly(p-phenylene sulfide), polyethylene dioxythiophene (PEDOT), etc. Other examples are oligothiophene, etc. The actual properties are in some cases more like properties of semiconductors than of conductors. In addition, “ITO” processed from metal can also be used.

[0089] However, these electroconductive materials are processed, synthesized, or combined, and cannot be said to be inexpensive and stable. From such a viewpoint, carbon (including carbon nanotubes) is the least expensive and most stable, and can be said to be a safe material for the human body.

Industrial Applicability

[0090] This invention inexpensively provides a biogalvanic battery therapeutic appliance that, despite the appliance having a high electrical resistance value and a long negative electrode constituent member, makes it possible to cause generated ions to efficiently flow to the negative electrode, and an excellent current stimulation effect of conductivity along the length of the negative electrode is obtained.

[0091] Specifically, the present invention functions particularly effectively in cases such as when the electrical resistance value is about 1 to 50 Ω .Math.cm, the length of the negative electrode constituent member is 20 to 50 mm, the thickness of the negative electrode constituent member is 150 .Math.m or less, and the “negative electrode constituent member length / negative electrode constituent member thickness” ratio is 1 or greater and preferably 100 or greater.

[0092] As a result, this biogalvanic battery therapeutic appliance, due to promoting blood circulation and purifying locally accumulated waste products, can be effectively used in the fields of beauty such as treatment and prevention of ailments such as stiff shoulders and lower-back pain, maintenance of beautiful skin, and improvement of skin quality.
