Technical Field

The present invention relates to a weak current sheet for causing a weak current to flow through the skin or the like. The present invention claims priority from japanese patent application No. 2018-009379, filed 24.1.2018, the contents of which are incorporated by reference into the present application for a given country where incorporation based on literature citation is admitted.

Background

Therapy for promoting health by causing a weak current to flow through the skin of a human is widely performed. It is said that applying a proper weak current to the human body improves the natural healing capacity of the human body. As a therapeutic method focusing on this, weak current Therapy (Microcurrent Therapy) can be mentioned. The weak current therapy is to promote the production of ATP (adenosine triphosphate) enzyme, the synthesis of protein, and the like necessary for the repair of a wound by applying a weak current manually from the outside. Weak current therapy is said to be particularly effective for the treatment of trauma. In addition, although not for the purpose of treating trauma, it is also widely practiced that: the weak current flows through the skin of a human body to adjust the bioelectric current that originally flows in the human body, and the ion arrangement of human cell tissues is adjusted, thereby playing a role in preventing and curing diseases and the like. As such weak current treatment devices, various weak current generating devices have been developed and made.

Patent document 1 describes an element for percutaneous medication in which a metal electrode having a potential higher than a standard unipolar potential and a semiconductor electrode having a potential lower than the standard unipolar potential are electrically connected, and a weak current is caused to flow by bringing the metal electrode and the semiconductor electrode into contact with the skin of a person.

Patent document 2 describes a weak current therapy device in which a piezoelectric body is provided in a flat plate shape on a substrate having elasticity and conductivity, the substrate and the piezoelectric body are fixed to the surface of a human body with an adhesive sheet, a protector, or the like, and a pressure is applied to the piezoelectric body to apply a weak current to the skin.

Disclosure of Invention

Problems to be solved by the invention

In the technique described in patent document 1, a metal electrode and a semiconductor electrode are used as the electrode. The materials that can be used for the semiconductor electrode are limited and are more expensive than the common metal electrode. The technique of patent document 1 is not completely satisfactory in that the metal electrode and the semiconductor electrode are connected by a wire, and is not sufficiently strong and thin, and is also not sufficiently satisfactory in that a weak current is applied to the entire surface of the electrode.

The technique of patent document 2 uses a piezoelectric body instead of an electrode having a potential difference. Since the piezoelectric body generates an electromotive force when pressure is applied, the weak current therapy device of patent document 2 needs to apply pressure. Since a weak current stably flows for a long time, it has an effect of adjusting a biological current in a human body, and thus a sufficient therapeutic effect cannot be obtained only by a structure in which a current flows when pressure is applied.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 and 2 show a weak current sheet according to an embodiment of the present invention. Fig. 1 is an exploded view showing the structure of a weak current sheet 1 according to the present embodiment, and fig. 2 is a transverse cross-sectional view of the weak current sheet 1 showing the flow of current.

As shown in fig. 1, the weak current sheet 1 includes a conductive sheet 2, a positive electrode foil 3, a negative electrode foil 4, and an insulating material 5.

The conductive sheet 2 may be a sheet having conductivity, and a metal sheet including an aluminum plate, a resin sheet including a metal film, a metal sheet, or the like, a resin sheet mixed with a conductor, conductive fibers, or the like may be used. The conductive sheet 2 may be a plate having hardness.

The positive electrode foil 3 and the negative electrode foil 4 are made of different metals having a potential difference, and may be in the form of a thin film or a thin metal sheet. The positive electrode foil 3 and the negative electrode foil 4 may be layers formed on the conductive sheet 2 by vapor deposition, sputtering (sputtering), plating, or the like.

These are also known as dissimilar metal contact corrosion, local batteries, and the like. The positive electrode foil 3 is also called a cathode (cathode) component, such as gold (Au +), with an atomic weight of 197.2, the standard electrode potential of +1.50V, and the negative electrode foil 4 is also called an anode (anode) component, such as aluminum (Al + + +), with an atomic weight of 26.97, the standard electrode potential of-1.337V, or zinc (Zn + +), with an atomic weight of 65.38, and the standard electrode potential of-0.762V, based on the standard electrode potential. Preferably, a metal that is easily formed on the conductive sheet 2 and that is harmless to the skin is appropriately selected.

By providing small irregularities on the surface of each of these electrode foils, the electrode foils can be smoothly brought into contact with the skin, contact with the skin can be promoted, and the electrode foils can be made uniform. The unevenness is provided, for example, in the form of a pattern formed by sandblasting, a line, a net, or a projection (pimple).

The insulating material 5 is made of an insulator, and is, for example, a sheet, a film, a layer, or the like. An insulating material 5 is disposed between the positive electrode foil 3 and the negative electrode foil 4 to cover the conductive sheet 2. The insulating material 5 may be in the form of a seal (seal) or may be formed by coating an insulator dissolved in a solvent.

In the following description, when an aluminum sheet is used for the conductive sheet 2 and gold is used for the positive electrode foil 3, for example, the conductive sheet 2 (aluminum sheet) is directly used as the negative electrode foil 4, so that it is not necessary to separately form the negative electrode foil.

Further, with the positive electrode foil 3, the positive electrode foil 3 is provided as the conductive sheet 2 by, for example, constituting the conductive sheet 2 with silver (Ag +) whose atomic weight is 107.88 and standard electrode potential is +0.799, or constituting the conductive sheet 2 with copper (Cu + +) whose atomic weight is 63.54 and standard electrode potential is +0.345, so that it is possible to eliminate the need to form the positive electrode foil.

The insulating material 5 may cover the conductive sheet 2, and as shown in fig. 1, the insulating material 5 may extend to a predetermined position inside the opposing edge portions of the positive electrode foil 3 and the negative electrode foil 4. That is, the opposing edge portions of the positive electrode foil 3 and the negative electrode foil 4 may overlap a portion of the insulating material 5. By extending the insulating material 5 to a predetermined position inside the facing edges of the positive electrode foil 3 and the negative electrode foil 4 in this way, it is possible to prevent the current from flowing due to a short circuit between the positive electrode foil 3 and the negative electrode foil 4 and the conductive sheet 2.

Fig. 2 shows a cross section of the weak current sheet 1 and a current flowing around the weak current sheet 1.

The positive electrode foil 3 and the negative electrode foil 4 have a potential difference, and thus contact with the skin 6 of a person forms a battery circuit through the skin 6. That is, ions are ionized from the negative electrode portion, electrons move to the positive electrode portion through the conductive portion, and a potential difference is generated between the positive electrode portion and the negative electrode portion. Here, the positive electrode portion refers to a portion of the positive electrode foil that comes into contact with the skin and functions as a positive electrode, and similarly, the negative electrode portion refers to a portion of the negative electrode foil that comes into contact with the skin and functions as a negative electrode. The conductive portion is a portion electrically connecting the positive electrode portion and the negative electrode portion, such as an electrically conductive sheet.

A weak current 7 flows in the dermal layer of the skin due to a potential difference between the positive electrode portion and the negative electrode portion. Since the current is weak, the current flows to a cell tissue below a dermis layer without damaging a horny layer on the surface of the skin, and the current adjusts the ion arrangement of the cell tissue, thereby having a cosmetic effect on the skin, and has effects of activating biological activities of a human body by flowing to an acupuncture point, curing and preventing diseases, and the like. Also, makeup dirt, old keratin, and the like are said to have cationic properties. As described above, the electrons moving to the positive electrode portion attract cosmetic dirt having a cationic property, and the like, and can remove dirt on the inside of pores that cannot be removed in ordinary skin care.

Also, for example, chronic arm pain (arm pain in the forties of forty years) and the like occur due to the rupture of fascia covering muscles. Generally, muscles are covered with fascia, and cracking, deformation, etc. of the fascia causes muscle pain, neuralgia, etc. Fascia is a membrane that wraps the muscles, from the small point of view it wraps the muscle fibers, and from the large point of view it wraps the entire body. It is effective for weak current such as muscular pain and neuralgia caused by rupture and deformation of fascia.

The muscle pain point (trigger point) is a point at which dysfunction of the fascia associated with shortening of the fascia is induced, and it itself induces pain, which causes pain at other sites. The muscle pain spots are also said to be caused by overloading the mechanical connection sites. Further, the myalgia site once causes atrophy, adhesion, etc., causes stiffness and pain, and it takes time to resolve them. The muscle pain points occur at overlapping points of fascia in different fiber directions, and these points are similar to the meridian points and acupuncture points of traditional Chinese medicine, and can be treated by applying stimulation to open the muscle pain points related to the fascia.

In recent years, fascia release has been attracting attention for atrophy of fascia and recovery of adhesions to normal conditions. The fascia release is said to have effects of smooth crossing movement of the fascia, promotion of blood flow of capillaries, improvement of flexibility of muscles, enlargement of the range of motion of joints, and improvement of the function of sensory nerves.

The weak current 7 flowing from the weak current sheet 1 stimulates fascia, muscle pain spots and the like under the skin, thereby being expected to have the effects of relieving pain of the muscle pain spots, eliminating atrophy, adhesion, fascia release and the like.

Further, a current 8 is discharged from a sharp portion such as a corner at the edge of the electrode foil. At the edge portion of the electrode foil in contact with the edge of the conductive portion, the electron current 9 flows in a short circuit manner through the skin 6. This portion is likely to be short-circuited if sweat adheres thereto. Such a current reaches only the stratum corneum, the top layer of the skin, and generally has no problem, but causes a loss of current, and the skin may turn red over a long period of time. Further, since the corners of the electrode plate press the skin, the resistance value at the pressed portion becomes small, and the current flow becomes abnormal more easily than at other portions. Therefore, the skin around the electrode plate is increasingly reddened. Therefore, in order to prevent such a current loss, a modification example shown in fig. 3 and 4 may be considered.

Fig. 3 shows a modification of the weak current sheet 1 of fig. 1. In the following drawings, the same reference numerals as those in fig. 1 are assigned to the same portions as those in fig. 1, and redundant description is omitted.

In fig. 3, the weak current sheet 1a is provided with a positive electrode foil 3 and a negative electrode foil 4 on a conductive sheet (not shown). In the weak current sheet 1a, the positive electrode foil 3 and the negative electrode foil 4 extend to predetermined positions inside the peripheral edge of the conductive sheet. That is, as shown in fig. 3, the positive electrode foil 3 and the negative electrode foil 4 extend only to a position at a distance d1 from the peripheral edge of the conductive sheet. In contrast, the insulating material 5a extends inward from the peripheral edge of the conductive sheet (or from a predetermined position on the outer side of the positive electrode foil 3 and the negative electrode foil 4) to a predetermined position on the inner side of the distance d2 from the edge of the outer peripheral portion of the positive electrode foil 3 and the negative electrode foil 4. In other words, the insulating material 5a covers the entire conductive sheet except for the central portions of the positive electrode foil 3 and the negative electrode foil 4, and the insulating material 5a extends to the position of the distance d2 inside the edges of the outer peripheral portions of the positive electrode foil 3 and the negative electrode foil 4. Accordingly, the positive electrode foil 3 and the negative electrode foil 4 are exposed except for the peripheral edge portions, and are insulated from each other by the insulating material 5 a. The exposed portions of the positive electrode foil 3 and the negative electrode foil 4 become a positive electrode portion and a negative electrode portion, respectively.

Fig. 4 shows a cross section of the weak current sheet 1 a. In this modification, as shown in fig. 4, the edges of the outer peripheral portions of the positive electrode foil 3 and the negative electrode foil 4 are located at a distance d1 from the edge of the conductive sheet 2. The positive electrode foil 3 and the negative electrode foil 4 extend to a distance d1 from the edge of the conductive sheet 2. In contrast, the outer peripheral portion 10 of the insulating material 5a extends inward from the edge of the conductive sheet 2, overlaps and extends to a position of a distance d2 inside the edges of the outer peripheral portions of the positive electrode foil 3 and the negative electrode foil 4 so as to cover a part of the positive electrode foil 3 and the negative electrode foil 4. Also, the opposing edges of the positive electrode foil 3 and the negative electrode foil 4 overlap with a part of the insulating material 5a so as to be covered with the insulating material 5 a.

The distance d1 from the edge is, for example, 0.5mm to 10mm, preferably 1mm to 5 mm. The distance d2 of the overlapping portion is, for example, 0.5mm to 6mm, preferably 1mm to 3 mm.

With this configuration, the current 8 from the corners of the electrode foil is interrupted by the outer peripheral portion 10 of the insulating material 5a and does not flow to the skin 6. In addition, in the peripheral edge portions of the conductive portion and the electrode portion, the current (electron current 9) flowing from the conductive portion to the positive electrode portion is also interrupted by the outer peripheral portion 10 of the insulating material 5a, so that the original weak current 7 flowing through the skin 6 is increased, and the skin does not turn red even when used for a long time.

Fig. 5 shows a weak current sheet according to another embodiment of the present invention. Fig. 5 (a) is an explanatory view showing the weak current sheet 1b according to the present embodiment in an exploded manner. Fig. 5 (b) is a cross-sectional view of the weak current sheet 1b viewed in the direction of the arrow a-a in fig. 5 (a).

The weak current sheet 1b is provided with a positive electrode foil 3b and a negative electrode foil 4b in an elongated shape on a rectangular conductive sheet 2 b. The positive electrode foil 3 and the negative electrode foil 4 are provided as positive and negative electrodes of at least 1, respectively, which are separated from each other and staggered in positive and negative, and are arranged substantially in parallel with each other. In the example of fig. 5 (a), there are 1 positive electrode foil 3b, 2 negative electrode foils 4b, the positive electrode foil 3b being disposed at the center, and the negative electrode foils 4b being disposed on both sides thereof. In addition, with this arrangement, a weak current flows from the positive electrode foil 3b (positive electrode section) to the negative electrode foils 4b (negative electrode sections) on both sides.

The positive electrode foil 3b and the negative electrode foil 4b extend to prescribed positions inside the peripheral edge of the conductive sheet 2 b. In the example of fig. 5 (a), the positive electrode foil 3b and the negative electrode foil 4b extend to positions of a distance d1 and a distance d 1' inside the peripheral edge of the conductive sheet 2 b. Distance d1 is the distance between the long side of the electrode foil and the edge of weak current sheet 1b, and distance d 1' is the distance between the short side of the electrode foil and the edge of weak current sheet 1 b. Alternatively, distance d1 and distance d 1' may be equal. The reason why the edge of the electrode foil is provided inside the conductive sheet 2b is to prevent direct short-circuit current from flowing from the conductive sheet 2b to the peripheral edge of the electrode foil.

The distance d1 from the longitudinal edge is, for example, 0.5mm to 15mm, preferably 1mm to 8 mm. The distance d2 of the overlapping portion is, for example, 0.5mm to 8mm, preferably 1mm to 5 mm.

The distance d 1' from the short-side edge is, for example, 0.5mm to 10mm, preferably 1mm to 5 mm. The distance d 2' of the overlapping portion is, for example, 0.5mm to 6mm, preferably 1mm to 3 mm.

An insulating material 5b is provided on the weak current sheet 1b, the positive electrode foil 3b, and the negative electrode foil 4 b. The insulating material 5b covers the entire conductive sheet 2b except for the positive electrode foil 3b and the negative electrode foil 4 b. The insulating material 5b extends from a predetermined position on the outer side of the positive electrode foil 3b and the negative electrode foil 4b (including the peripheral edge of the conductive sheet 2 b) to a predetermined position on the inner side of each electrode foil. That is, the insulating material 5b extends to a position inward from the peripheral edges of the positive electrode foil 3b and the negative electrode foil 4b by a distance d2 and a distance d 2'. The distance d2 is the distance by which the long-side portion of the electrode foil overlaps the insulating material 5b, and the distance d 2' is the distance by which the short-side portion of the electrode foil overlaps the insulating material 5 b. Alternatively, distance d2 and distance d 2' may be equal. The reason why the edge of the electrode foil and the insulating material 5b are partially overlapped in this way is to prevent direct short-circuit current from flowing from the conductive sheet 2b to the positive electrode foil 3b and the negative electrode foil 4 b.

Fig. 5 (b) is a cross-sectional view of the weak current sheet 1b viewed in the direction of the arrow a-a in fig. 5 (a), and it can be seen that: the long side portions of the positive electrode foil 3b and the negative electrode foil 4b are covered with the insulating material 5b, and short-circuit current does not flow from the conductive sheet 2 b.

Fig. 6 is a cross-sectional view of the weak current sheet 1B viewed in the direction of the arrow B-B in fig. 5 (a), and it can be seen that: short side portions of the positive electrode foil 3b and the negative electrode foil 4b are covered with the insulating material 5b, and short-circuit current does not flow from the conductive sheet 2 b.

In the weak current sheet 1b, the positive electrode foil 3b and the negative electrode foil 4b are separated from each other and insulated by an insulating material 5 b. When the positive electrode portion and the negative electrode portion come into contact with human skin, ions are ionized from the negative electrode portion due to a potential difference, and electrons are collected in the positive electrode portion through the conductive portion. Accordingly, a potential difference is generated between the positive electrode portion and the negative electrode portion, and a weak current flows through human skin. In the weak current sheet 1b, since the negative electrode foils 4b are provided on both sides of the positive electrode foil 3b, a weak current flows from the central positive electrode portion to the negative electrode portions on both sides. Since the portion of the edge of the electrode portion and the portion of the edge of the conductive portion are insulated by the insulating material 5b, the current is not short-circuited and a weak current flows efficiently.

Fig. 7 shows a modification of the weak current sheet 1 b.

In the weak current sheet 1c of fig. 7, the bottom surface of the conductive sheet 2c is covered with the insulating sheet 11. Preferably, the insulating sheet 11 extends outward from the peripheral edge of the conductive sheet 2c and is connected to the insulating material 5 c. That is, the insulating material 5c completely insulates the peripheral edge of the conductive sheet 2c including the side surface thereof, and also insulates the peripheral edge of the positive electrode foil 3 c.

By insulating the bottom surface of the conductive sheet 2c with the insulating sheet 11, no current flows from the bottom surface of the conductive sheet 2c to the outside when the weak current sheet 1c is used. Accordingly, a weak current of a battery circuit formed between the battery and the living body can be effectively used.

Fig. 8 is an exploded view showing a weak current sheet according to another embodiment of the present invention.

The weak current sheet 1d of the present embodiment includes an insulating sheet 11d, and a conductor 12 on the insulating sheet 11 d. Preferably, the conductor 12 has an elongated shape, and both ends of the conductor 12 extend to a level short of the edge of the insulating sheet 11 d.

The conductor 12 is provided with a positive electrode foil 3d and a negative electrode foil 4d which are made of different metals having a potential difference and are electrically connected to the conductor 12, the positive electrode foil 3d and the negative electrode foil 4d being provided separately. Preferably, the end portions of the positive electrode foil 3 and the negative electrode foil 4 extend to such an extent that they do not reach the edge of the insulating sheet 11 d.

An insulating material 5d is provided over the positive electrode foil 3d and the negative electrode foil 4 d. The insulating material 5d is provided so as to cover at least the electric conductor 12 between the positive electrode foil 3d and the negative electrode foil 4 d. Preferably, the insulating material 5d extends to a predetermined position inside each of the opposing edge portions of the positive electrode foil 3d and the negative electrode foil 4 d. Further, it is preferable that the insulating material 5d covers the entire surface insulating sheet 11d except for the positive electrode foil 3d and the negative electrode foil 4 d. Preferably, the insulating material 5d overlaps with part of the peripheral edges of the positive electrode foil 3d and the negative electrode foil 4d, and extends from the peripheral edges of the positive electrode foil 3d and the negative electrode foil 4d to predetermined positions on the inner sides of the respective electrode foils.

Fig. 9 is a sectional view as seen in the direction of arrows C-C of fig. 8.

As is clear from fig. 9, the insulating sheet 11d extends longer than the end of the positive electrode foil 3d and is connected to the insulating material 5 d. The insulating material 5d covers the end of the positive electrode foil 3d including the side surface thereof, and extends from the peripheral edge of the positive electrode foil 3d to a predetermined position inside the positive electrode foil 3 d.

In addition, the positive electrode foil 3d and the negative electrode foil 4d are provided so that at least 1 electrode foil per polarity is provided, and at least 2 electrode foils in total are provided so as to be staggered in the positive and negative directions.

Fig. 10 shows a weak current sheet according to another embodiment of the present invention having a humectant.

The weak current sheet 1e has a weak current sheet 1a having a structure shown in fig. 3. That is, the conductive sheet 2 is provided with the positive electrode foil 3 and the negative electrode foil 4, on which the insulating material 5a is provided. The insulating material 5a extends from the peripheral edge portions of the positive electrode foil 3 and the negative electrode foil 4 to predetermined positions on the inner sides of the respective electrode foils. The positive electrode foil 3 and the negative electrode foil 4 are exposed except for the peripheral edge portions. A humectant 13 is provided on the positive electrode foil 3 and the negative electrode foil 4. The moisturizing agent 13 on the positive electrode foil 3 and the moisturizing agent 13 on the negative electrode foil 4 are separated from each other. Accordingly, the flow of current between the electrode portions is prevented by the humectant 13.

The electrode sheet should be attached with the moisturizing agent in use, but the electrode sheet may be attached with the moisturizing agent 13 in advance. Therefore, the paper can be used immediately by peeling off the release paper.

The humectant 13 is, for example, a gel having moisture retention properties, or a nonwoven fabric or the like containing moisture, glycerin, urea, hyaluronic acid, collagen, or the like, and has a thickness of, for example, 0.5mm to 6mm, preferably, 1mm to 4 mm.

Fig. 11 shows the flow of current when the weak current sheet 1e is used.

The moisturizer 13 has conductivity and can be brought into close contact with the skin 6. Here, the electrode portion functions as a positive electrode or a negative electrode by contacting the skin with the moisturizing agent 13. Therefore, when the weak current sheet 1e is stuck to the skin 6, the moisturizer 13 is brought into close contact with the skin 6, and ions are eluted from the negative electrode portion to the moisturizer 13 due to the potential difference between the positive electrode foil 3 (positive electrode portion) and the negative electrode foil 4 (negative electrode portion). The electrons of the negative electrode portion flow to the positive electrode portion through the conductive sheet 2 (conductive portion), and the positive electrode portion has a potential difference with respect to the negative electrode portion. Since the moisturizer 13 has conductivity, the moisturizer 13 on the positive electrode part has a potential difference with respect to the moisturizer 13 on the negative electrode part, and the weak current 7 flows in the skin 6 by attracting cations in the cell tissue. By separating the moisturizer 13 of the positive electrode section from the moisturizer 13 of the negative electrode section, as shown in fig. 11, a weak current 7, not a current 7', flows inside the skin 6. The ionic arrangement of the cell tissue of the skin 6 is adjusted through the weak current 7, so that the effects of beautifying the skin or curing and preventing diseases and the like are achieved.

Fig. 12 shows a modification of the weak current sheet 1 e.

The weak current sheet 1f of fig. 12 has a detachable release paper 14 on the moisturizing agent 13 of the weak current sheet 1 e. A pressing plate 15 is provided on the bottom surface of the conductive sheet 2 of the weak current sheet 1 e. The press plate 15 is preferably bonded to the conductive plate 2.

Since the humectant 13 has moisture and adhesiveness, it is easy to store and handle it before use by sticking the release paper 14 in advance.

Preferably, the pressing plate 15 has a certain thickness and elasticity, such as a sponge, for example. By providing the pressure plate 15, when the weak current sheet 1f is adhered to the skin by, for example, an adhesive tape, a protector, or the like, the weak current sheet 1f can be brought into close contact with the skin by the thickness and elasticity of the pressure plate 15.

Fig. 13 is an exploded view showing a weak current sheet according to another embodiment of the present invention.

The weak current sheet 1g of the present embodiment has an electrode sheet 1a having a structure shown in fig. 3. That is, the positive electrode foil 3 and the negative electrode foil 4 are provided on the conductive sheet 2g, and the insulating material 5g is provided thereon. The insulating material 5g extends from the peripheral edge portions of the positive electrode foil 3 and the negative electrode foil 4 to predetermined positions on the inner sides of the respective electrode foils, and exposes the positive electrode foil 3 and the negative electrode foil 4 except for the peripheral edge portions. A moisturizing agent 13 is separately provided on the positive electrode foil 3 and the negative electrode foil 4.

In the present embodiment, the weak current sheet 1g is folded in a ridge shape at a portion between the positive electrode foil 3 and the negative electrode foil 4 to form a separation plate 1 g'. Since the surface of the separator 1 g' is the insulating material 5g, it has an insulating property, and stands between the humectant 13 of the positive electrode foil 3 and the humectant 13 of the negative electrode foil 4, and can insulate the humectant 13 of the positive electrode foil 3 (positive electrode portion) and the humectant 13 of the negative electrode foil 4 (negative electrode portion).

Since the humectant 13 has a certain degree of fluidity, it is considered that the humectant 13 of the positive electrode portion and the humectant 13 of the negative electrode portion flow and come into contact with each other when used for a long time, and a weak current may short-circuit. However, by providing the separation plate 1 g', contact due to the flow of the humectant 13 can be prevented, and a weak current can be caused to flow through the cell tissue of the human body for a long time.

Fig. 14 is an exploded view showing a weak current sheet according to another embodiment of the present invention.

In the weak current sheet 1h of the present embodiment, a positive electrode foil 3 and a negative electrode foil 4 are provided on the conductive sheet 2, and an insulating material 5 is provided on the positive electrode foil 3 and the negative electrode foil 4. The insulating material 5 extends to a predetermined position inside the peripheral edge portions of the positive electrode foil 3 and the negative electrode foil 4, and the positive electrode foil 3 and the negative electrode foil 4 are exposed except for the peripheral edge portions.

A humectant 13 is separately provided on the positive electrode foil 3 and the negative electrode foil 4. A separator 16 is provided between the humectant 13 of the positive electrode foil 3 and the humectant 13 of the negative electrode foil 4, and the separator 16 has an insulating property and preferably also a water-repellent property. The separate body 16 may be formed of, for example, a foamed plastic.

By providing the separator 16 between the humectant 13 of the positive electrode foil 3 and the humectant 13 of the negative electrode foil 4, contact due to the flow of the humectant 13 can be prevented, and a weak current can be caused to flow through the cell tissue of the human body for a long time.

Fig. 15 is an exploded view showing a weak current sheet according to another embodiment of the present invention.

In the weak current sheet 1i of the present embodiment, a positive electrode foil 3 and a negative electrode foil 4 are provided on a conductive sheet 2, and an insulating material 5 is provided on the positive electrode foil 3 and the negative electrode foil 4. The insulating material 5 extends to a predetermined position inside the peripheral edge portions of the positive electrode foil 3 and the negative electrode foil 4, and the positive electrode foil 3 and the negative electrode foil 4 are exposed except for the peripheral edge portions. A humectant 13 is separately provided on the positive electrode foil 3 and the negative electrode foil 4.

A separation paper 17 is provided between the moisturizing agent 13 of the positive electrode foil 3 and the moisturizing agent 13 of the negative electrode foil 4. The separation paper 17 is made of insulating paper, and is preferably bent in a crank (crank) shape as shown in fig. 15. The paper having insulation properties includes paper coated with a resin such as vinyl resin, resin paper, and the like. By folding the separator 17 in a crank shape and inserting the separator into the humectant 13, even if the humectant 13 flows, the two do not contact each other, and a weak current can be made to flow through the cell tissue of the human body for a long time.

Fig. 16 is an exploded view showing a weak current sheet according to another embodiment of the present invention.

The weak current sheet 1j of the present embodiment has a conductive sheet 2, and an insulating sheet 18 having a long hole 18' is provided on the conductive sheet 2. On the insulating sheet 18, a positive electrode foil 3j and a negative electrode foil 4j having an elongated shape are provided in a direction orthogonal to the longitudinal direction of the long hole 18'. At the portion of the elongated hole 18', a part of the positive electrode foil 3j and the negative electrode foil 4j is electrically connected to the conductive sheet 2. The portion of the conductive sheet 2 between the positive electrode foil 3j and the negative electrode foil 4j is exposed through the elongated hole 18'.

An insulating material 5j is provided on the positive electrode foil 3j and the negative electrode foil 4 j. The insulating material 5j covers at least the conductive sheet 2 between the positive electrode foil 3 and the negative electrode foil 4 exposed from the elongated hole 18'. Accordingly, the positive electrode foil 3j and the negative electrode foil 4j are insulated from each other. In the example of fig. 16, the insulating material 5j covers the entire elongated hole 18'. Accordingly, the positive electrode foil 3j and the negative electrode foil 4j form a pair of electrode portions that are bilaterally symmetrical in fig. 16.

In order to prevent short-circuit current loss from the end portions of the positive electrode foil 3j and the negative electrode foil 4j, the positive electrode foil 3j and the negative electrode foil 4j extend only to positions inward from the peripheral edge portions of the insulating sheet 18 by a predetermined distance. The insulating material 5j extends inward from the peripheral edge of the insulating sheet 18 to a position inward from the end portions of the positive electrode foil 3j and the negative electrode foil 4j by a predetermined distance.

When the weak current sheet 1j is attached to the skin or the like, a potential difference is generated between the positive electrode portion (positive electrode portion formed by dividing the positive electrode foil 3 j) and the negative electrode portion (negative electrode portion formed by dividing the negative electrode foil 4 j), and a weak current flows from the positive electrode portion at the center portion to the negative electrode portions at both sides. Since the positive electrode portion and the negative electrode portion are insulated from the conductive portion, short-circuit current does not flow. In addition, at both ends of the positive electrode portion 3j and the negative electrode portion 4j, the ends of the positive electrode portion 3j and the negative electrode portion 4j are positioned at a predetermined distance inward from the peripheral edge of the conductive sheet 2 and are insulated by the insulating material 5j, so that the current can be prevented from flowing out from the peripheral edge of the conductive sheet 2. Therefore, it is possible to effectively exert effects such as a cosmetic effect, a healing effect, and a disease prevention effect by using a weak current of a battery formed between the potential difference electrode and the living body without waste.

Fig. 17 shows a modification of the weak current sheet 1 j.

The weak current sheet 1j of fig. 17 is formed of an elastomer material into a conductive sheet 2 j. As the elastomer material, a sponge having conductivity or the like can be used. The end portions of the positive electrode foil 3j and the negative electrode foil 4j extend inward from the peripheral edge portion of the conductive sheet 2 to a position of a distance d 1. The insulating material 5j extends from the peripheral edge of the conductive sheet 2 to the position of a distance d2 inside the end portions of the positive electrode foil 3j and the negative electrode foil 4j, covering the end side surfaces of the positive electrode foil 3j, the negative electrode foil 4j, and the insulating sheet 18 j.

By using the conductive sheet 2j made of an elastic material, the electrode foil can be easily brought into close contact with the skin even on the uneven surface. In this case, it is not necessary to attach a separate platen to the conductive sheet 2j, and the structure can be simplified, thereby reducing material costs. When the weak current sheet 1j is fixed to the skin with an adhesive tape, a protector, or the like, it can be brought into close contact with the uneven surface, and a stable and effective weak current can be obtained.

Fig. 18 shows a modification of fig. 17.

The weak current sheet 1k of this embodiment also forms the conductive sheet 2k with an elastomer material. The weak current sheet 1j differs from that of fig. 17 in that the end portions of the positive electrode foil 3k and the negative electrode foil 4k coincide with the peripheral edge of the conductive sheet 2k, the peripheral edge of the insulating material 5j, and the peripheral edge of the insulating sheet 18 k.

Although the short-circuit current flows from the end of the electrode foil because the end of the electrode foil coincides with the peripheral edge of the conductive sheet, the influence is small because the end of the electrode foil is short, and the peripheral edge portion other than the end of the electrode foil is insulated by the conductive sheet 2k, so that the weak current can efficiently flow.

The electrode structure of the weak current sheet of the present invention will be described below.

Fig. 19 (a) shows a basic weak current sheet 1 m. In the weak current sheet 1m, positive electrode foils 3m and negative electrode foils 4m are arranged on a conductive sheet 2m in a positive-negative staggered manner, and the positive electrode foils 3m and the negative electrode foils 4m are electrically connected with the conductive sheet 2 m. The conductive sheet 2m is a conductive sheet, and is not limited to a plate shape, and may be a mesh shape, a lattice shape, or the like. As the conductive sheet 2m, a metal sheet, a resin sheet including a metal film, a metal sheet, or the like, a resin sheet mixed with a conductor, conductive fibers, or the like can be used. The conductive sheet 2m may be a plate having hardness.

The positive electrode foil 3m and the negative electrode foil 4m are made of different metals having a potential difference, and may be thin films or thin metal sheets. The insulating material 5m is an insulator, and is a sheet, a film or a layer formed on the conductive sheet 2m, or the like.

Since the positive electrode foil 3m and the negative electrode foil 4m are insulated, the insulating material 5m needs to cover the conductive sheet 2m between the positive electrode foil 3m and the negative electrode foil 4 m. Preferably, the insulating material 5m extends to a position inwardly from the edges of the positive electrode foil 3m and the negative electrode foil 4m by a prescribed distance. This is to prevent short-circuiting of the positive electrode foil 3m, the negative electrode foil 4m, and the conductive sheet 2 m.

Fig. 19 (b) shows the case where the conductive sheet 2m is directly used as the negative electrode foil 4m as described above. The conductive sheet 2m has a potential lower than that of the positive electrode foil 3 m. When the conductive sheet 2m and the positive electrode foil 3m separated by the insulating material 5m come into contact with the skin or the like, a battery circuit is formed between the negative electrode portion and the positive electrode portion and the skin, and a weak current can flow. According to the conductive sheet 2m, a weak current sheet having a simple structure can be obtained without additionally providing a negative electrode foil.

Fig. 20 shows an electrode structure of another weak current sheet 1 n. The weak current sheet 1n is provided with a negative electrode foil 4n on the conductive sheet 2 n. Further, a positive electrode foil 3n is provided on the negative electrode foil 4 n. Preferably, the negative electrode foil 4n has an elongated shape, and the positive electrode foil 3n is disposed to intersect the negative electrode foil 4 n. The insulating material 5n covers the connecting portion of the edge portion of the negative electrode foil 4n and the conductive sheet 2n and the connecting portion of the edge portion of the positive electrode foil 3n and the negative electrode foil 4 n.

The polarity of the electrode foil may be reversed. That is, it is also possible to dispose the positive electrode foil 3n on the conductive sheet 2n and the negative electrode foil 4n thereon.

Since the connecting portion between the edge portions of the positive electrode foil 3n and the negative electrode foil 4n is insulated, a potential difference is generated as an electrode when the positive electrode portion of the positive electrode foil 3n and the negative electrode portion of the negative electrode foil 4n are in contact with the skin, and a battery circuit can be formed.

Fig. 21 shows a plan view and a cross-sectional view of a modification of fig. 20. The weak current sheet 1p of fig. 21 is identical in structure to the weak current sheet 1n of fig. 20. That is, a negative electrode foil 4p is provided on the conductive sheet 2p, and a positive electrode foil 3p is provided on the negative electrode foil 4 p. However, in the example of fig. 21, the positive electrode foil 3p and the negative electrode foil 4p have circular shapes, and the insulating material 5p has a ring shape. The connecting portion of the edge portion of the negative electrode foil 4p and the conductive sheet 2p and the connecting portion of the edge portion of the positive electrode foil 3p and the negative electrode foil 4p are enclosed by an insulating material 5 p. The polarity of the electrode foil may be reversed, as in the case of the weak current sheet 1 n.

The weak current sheet 1p has a large surface area of the positive electrode foil, and thus the current from the positive electrode portion becomes large. As shown in fig. 21, the negative electrode portion surrounds the periphery of the positive electrode portion, and thus a weak current flows from the center to the circumferential portion. The weak current sheet 1p is suitable for muscle pain spots, meridians and collaterals, acupuncture points and the like.

Fig. 22 shows a transverse cross-sectional view of a weak current sheet provided with an adhesive and a base plate.

When the weak current sheet in fig. 23 (a) is used for thick muscles such as a muscle in a crotch region, the weak current sheet is attached so as to wind the muscle in the longitudinal direction of the sheet and allow a current to flow perpendicularly to the extending direction of the muscle, so that stimulation can be applied by allowing a current to flow such as to divide the entire muscle, and a single muscle can be treated.

On the other hand, the weak current sheet in fig. 23 (b) is attached to a portion where the direction of each muscle is along the direction of the toes, such as the instep, so that the long direction of the weak current sheet faces the both sides of the instep, and current is generated in each toe in the same direction as the extending direction of the muscle of the toe, thereby applying stimulation to each toe at once.

Accordingly, when used, the peripheral edge of the patch 26a adheres to the skin or the like, and the weak current sheet 1x can be fixed to the skin or the like. The structure of the electrode of the weak current sheet 1x may be any structure. The weak current sheet 1x is suitable for being attached to the lower part of the eye, the cheek, or the like due to its shape.

The patch 26b has a crescent shape in its outer shape, but has an opening 28 in its interior. The peripheral edge of the opening 28 has a shape overlapping the peripheral edge of the weak current sheet 1x, and a part of the opening overlaps (coincides) with the outer periphery of the weak current sheet 1x to form a peeled portion 28'. Preferably, the peeling section 28' is provided at a place where the change in curvature of the outer periphery of the weak current sheet 1x is large, for example, at one end of the weak current sheet 1x as shown in fig. 33. The number of the peeling portion 28' is not limited to one, and may be plural.

The tape 31 has an elastic portion 32 and an adhesive portion 33. The elastic portion 32 can have any shape according to the shape of the weak current sheet 1 x. In the example of fig. 35, the weak current sheet 1x has a crescent shape, and therefore the elastic portion 32 has a T-shape as shown in the drawing. The elastic portion 32 is made of a material having elasticity, and for example, rubber, elastic fabric, or the like can be used.

The adhesive portion 33 is provided at an end of the elastic portion 32. In use, the adhesive part 33 is pulled in the direction of the arrow shown in fig. 35 and adhered to the skin. The elastic portion 32 is stretched to bring the weak current sheet 1x into close contact with the skin. Since the weak current sheet 1x has the pressure pad 30, it can be brought into close contact with the irregularities of the skin. Is especially suitable for use around eyes such as canthus and fine parts such as corner of mouth.

Fig. 36 is a cross-sectional view of a weak current sheet 1x provided with a pressure pad 30. The pressure pad 30 is made of a material having flexibility and elasticity, and for example, silicone rubber or the like can be used.

Fig. 38 is a perspective view (fig. 38 (a)) and an explanatory view of a use state (fig. 38 (b)) of a weak current sheet according to another embodiment of the present invention.

The weak current sheet 1y of the present embodiment includes an auxiliary presser 34. The auxiliary presser 34 has a substantially rectangular shape with a wide width, and both ends of the main body portion 35 are bent to have a rising portion 36 and a horizontal portion 37. The horizontal portion 37 has holes 38, and a belt 39 is attached to the holes 38. Preferably, the belt 39 is in the shape of a loop, and the belt 39 may be an elastic material such as rubber. The belt 39 may be a flexible belt that can be tied at both ends.

The weak current sheet 1y and the auxiliary presser 34 according to this embodiment can be used, for example, for the face, and as shown in fig. 38 (b), the auxiliary presser 34 is provided on the side of the nose 40 by the rising portion 36 of the auxiliary presser 34, and the weak current sheet 1y is brought into contact with the cheek or the like. After that, the band 39 is fitted over the ear or the like. Since the rising portion 36 has a certain degree of elasticity, the weak current sheet 1y can be pressed against the cheek or the like by being pulled by the strap 39. According to the present embodiment, the weak current sheet 1y can be pressure-bonded to the cheek or the like with a certain degree of pressure, and the weak current sheet 1y can be prevented from floating.

Fig. 39 shows a weak current sheet according to another embodiment of the present invention. Fig. 39 (a) is an exploded view showing the structure of the weak current sheet 1z according to the present embodiment. Fig. 39 (b) shows a use state of the weak current sheet 1z according to the present embodiment. Fig. 40 shows a modification of the weak current sheet 1z according to the present embodiment.

As shown in fig. 39 (a), the weak current sheet 1z of the present embodiment includes a positive electrode sheet 41, a negative electrode sheet 42, and a conductive sheet 43.

The positive electrode sheet 41 has a patch 26z made of an insulating material. The patch 26z has an adhesive on the entire back surface thereof, and a positive electrode foil 3z made of a conductive material is bonded thereto. The patch 26z has a shape similar to the positive electrode foil 3z, is larger in size than the positive electrode foil 3z, and extends from the peripheral edge of the positive electrode foil 3z when the positive electrode foil 3z is attached. Accordingly, positive electrode foil 3z can be brought into close contact with the skin or the like by adhering the peripheral edge of patch 26z to the skin or the like. The patch 26z has an opening 49, and when the positive electrode foil 3z is attached to the back surface, the positive electrode is exposed through the opening 49 to form a positive electrode exposed portion 44.

On the other hand, the negative electrode tab 42 also has a patch 26z made of an insulating material, and has an adhesive on the entire back surface. A negative electrode foil 4z made of a conductive material is also attached to the back surface of the patch 26 z. Similarly to the positive electrode sheet 41, the negative electrode sheet 42 has the patch 26z larger in size than the negative electrode foil 4z and extends from the peripheral edge of the negative electrode foil 4z, so that the negative electrode foil 4z can be adhered to the skin or the like. The patch 26z of the negative electrode sheet 42 also has an opening 49, and when the negative electrode foil 4z is attached, the negative electrode is exposed through the opening 49 to become a negative electrode exposed portion 45.

The conductive sheet 43 is a strip for conducting the positive electrode sheet 41 and the negative electrode sheet 42, and has a patch 46 made of an insulating material. The patch 46 has adhesive on the entire back surface to which the conductive strips 47 are adhered. The patch 46 is larger in size than the conductive strip 47, and in particular, has two end portions extending outward from the periphery of the conductive strip 47, and adheres the conductive strip 47 to the positive electrode sheet 41 and the negative electrode sheet 42. A rear surface insulating portion 48 is provided on the rear surface of the central portion of the conductive sheet 43, so that both end portions of the conductive strip 47 are exposed, and the portion between both end portions of the conductive strip 47 is insulated.

Fig. 39 (b) shows a use state of the weak current sheet 1z after assembly.

With the weak current sheet 1z, the positive electrode sheet 41 and the negative electrode sheet 42 need to be respectively stuck to desired parts of the body. The desired part of the body is a part where a weak current is intended to flow, and examples thereof include an acupuncture point part of the body, a muscle part which becomes stiff, and the like. Since the patches 26z extend from the peripheral edges of the positive electrode foil 3z and the negative electrode foil 4z, the positive electrode foil 3z and the negative electrode foil 4z can be adhered to any part of the body.

After that, both end portions of the conductive strip 47 on the back surface of the conductive sheet 43 are aligned with the positive electrode exposed portion 44 of the positive electrode foil 3z and the negative electrode exposed portion 45 of the negative electrode foil 4z, respectively, and the conductive sheet 43 is pasted. By attaching the conductive sheet 43 in this manner,: the positive electrode foil 3z and the negative electrode foil 4z are electrically connected, and the back surface insulating portion 48 insulates the central portion of the back surface of the conductive sheet 43, and the positive electrode foil 3z and the negative electrode foil 4z are in contact with the skin or the like. Since the positive electrode foil 3z and the negative electrode foil 4z have a potential difference, a battery circuit is formed via the body, and a weak current flows between the positive electrode foil 3z and the negative electrode foil 4 z. The weak current does not damage the stratum corneum of the skin surface, flows to the cell tissue below the dermis layer, has skin caring effect, and has effects of activating biological activity, curing, and preventing diseases for acupuncture points.

According to the present embodiment, since the both ends of the conductive strip 47 of the conductive sheet 43, the positive electrode exposed portion 44, and the negative electrode exposed portion 45 can be connected to each other, a biological battery can be formed, and therefore, the biological battery can be used even if the distance between the positive electrode sheet 41 and the negative electrode sheet 42 is somewhat different. Therefore, the positions of the acupuncture points can be adjusted to different positions among individuals, and the acupuncture points can be used in the most effective places.

Fig. 40 shows a modification of the weak current sheet 1 z. The weak current sheet 1zz of this embodiment has the same configuration as the weak current sheet 1z shown in fig. 39 (a) and 39 (b), except that the conductive sheet 43zz is different.

The conductive sheet 43zz of the present embodiment can correspond to a change in the distance between the positive electrode sheet 41 and the negative electrode sheet 42. Specifically, the patch 46zz and the conductive strip 47zz of the conductive sheet 43zz are made to have an arcuate bend or a bellows-like bend. Accordingly, a change in the distance between the positive electrode sheet 41 and the negative electrode sheet 42 can be absorbed by expansion and contraction of the bent portion or the bent portion.

Alternatively, the patch 46zz and the conductive strip 47zz of the conductive sheet 43zz may be formed of a member having elasticity. Specifically, for example, the patch 46zz may be formed of a resin material having elasticity, and the conductive strip 47zz may be formed of a flexible strip in which a bent conductive wire is embedded. According to the present embodiment, the conductive sheet 43zz can be extended and contracted in accordance with a change in the distance between the positive electrode sheet 41 and the negative electrode sheet 42, and the positive electrode sheet 41 and the negative electrode sheet 42 can be electrically connected.

Alternatively, the positive electrode exposed portion 44 and the negative electrode exposed portion 45 may be laterally wide, and the exposed portions at both ends of the conductive strip 47zz may be provided slightly longer. By this method, even if the distance between the positive electrode sheet 41 and the negative electrode sheet 42 varies, the two electrode sheets 41 and 42 can be electrically connected to each other by moving the connecting portions of the conductive strips 47zz with the positive electrode exposed portion 44 and the negative electrode exposed portion 45. Accordingly, a change in the distance between the positive electrode sheet 41 and the negative electrode sheet 42 can be absorbed.

The conductive sheets 43 and 43zz have a patch structure and a conductive strip structure, but are not limited thereto, and the conductive sheets may be conductive sheets as long as they electrically connect the conductive portions of the positive electrode sheet and the negative electrode sheet, and may be, for example, formed of a flexible conductor (which may not be a strip), and the surface of the conductor may be insulated from the central portion of the back surface where the positive electrode sheet and the negative electrode sheet are in contact.

The positive electrode foil 3z and the negative electrode foil 4z are bonded to each other at the peripheral edge of the patch 26z, but the positive electrode foil 3z and the negative electrode foil 4z may have an adhesive.

The positive electrode sheet 41 and the negative electrode sheet 42 are oval, but the positive electrode sheet 41 and the negative electrode sheet 42 may have any shape. Further, the electrode sheet may be combined with a moisture retention material. Further, the humectant may be on only one side, such as the positive electrode side.
