Description

[Technical field]

[0001] The present invention relates to a ground potential conductor for use in an electric potential therapy device and an electric potential therapy device equipped with the ground potential conductor. [Background technology]

[0002] Conventionally, there is known a potential therapy device that applies a high AC voltage to the human body to perform treatment. For example, Patent Document 1 discloses a potential therapy device that has a power supply circuit connected to an AC power supply, an inverter connected to the output side of the power supply circuit to generate an AC voltage of an arbitrary waveform, and a transformer that boosts the AC voltage generated by the inverter to an output voltage, and transmits the boosted output voltage to a conductor to apply it to the human body.

[0003] It is also known that in this type of electric potential therapy device, a conductor that locally discharges electric potential is used to locally lower the electric potential of the human body to which high voltage electric potential is supplied, providing an electric potential gradient, and a therapeutic current is passed to obtain a therapeutic effect.For example, Patent Document 2 discloses an electrode pad for high voltage electric potential therapy that is used to locally discharge the high voltage electric potential that has flowed into the body of the person being treated in electric potential therapy using an electric potential therapy device. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-073372 A [Patent Document 2] JP 2007-185369 A Summary of the Invention [Problem to be solved by the invention]

[0005] The above-mentioned conventional electric potential treatment devices have some points that need to be improved in order to provide effective and safe treatment to a wide range of treatment target areas. Specifically, Patent Document 2 discloses a configuration in which an electrode pad for high-voltage potential treatment is attached via a gel sheet to a human body to which a high potential is applied, and a treatment current is passed locally. However, in a conventional potential treatment device using such an electrode pad, when the treatment target area is large, it is difficult to pass suitable treatment electrons to the entire area of ​​the treatment target area.

[0006] That is, the electrode pad of the prior art disclosed in Patent Document 2 can perform localized treatment by discharging electricity from the site where the electrode pad is attached. However, the electrode pad is a square with each side of about 50 mm, and it is not possible to perform treatment by passing suitable therapeutic electrons over a wide area, for example, from both shoulders to the back.

[0007] In addition, in the case of conventional electric potential therapy devices, when a wide area is treated, the electrode pad for high voltage electric potential therapy may be moved. For example, the electrode pad may be held by hand, peeled off from the area to be treated, and moved to another area to be treated and attached thereto, or the electrode pad placed on the area to be treated may be held by hand and moved in a rubbing motion over the wide area to be treated. In such cases, there is a problem that unintended current may flow to the hand holding the electrode pad.

[0008] In addition, when an electrode pad attached to a treatment target area is pressed down with a hand to prevent the electrode pad from peeling off from the treatment target area during treatment, an unintended current may flow to the hand pressing down the electrode pad.

[0009] The present invention has been made in consideration of the above-mentioned circumstances, and its object is to provide a ground potential conductor and a potential therapy device equipped with the same that can supply suitable therapeutic electrons to a wide treatment target area, thereby enabling effective treatment to be performed efficiently and safely. [Means for solving the problem]

[0010] The ground potential conductor of the present invention is a ground potential conductor that is attached to a human body to which a high voltage is applied and that flows electrons for treatment, and is characterized in that it comprises a conductive electrode that is configured in a flexible, planar form and connected to a ground potential wiring, an insulating inner surface member that covers the surface of the electrode that comes into contact with the human body, and an insulating outer surface member that covers the surface of the electrode that does not come into contact with the human body, and has an overall shape that is formed symmetrically, and a cut portion that opens to the left and right in the center of the left and right and is large enough to allow the person to be treated to pass their neck through.

[0011] In addition, the electric potential therapy device of the present invention comprises a high-voltage transformer which boosts an input potential to generate a high-voltage output potential, and a high-voltage lead which is connected to the high-voltage transformer and placed in close contact with the human body to apply the output potential to the human body, and is characterized in that it is equipped with the above-mentioned ground potential lead of the present invention. Effect of the Invention

[0012] The ground potential conductor of the present invention is a ground potential conductor that is attached to a human body to which a high voltage is applied and that passes electrons for treatment, and includes a conductive electrode that is configured in a flexible planar shape and connected to a wiring of a ground potential, an insulating inner surface member that covers the surface of the electrode that is in close contact with the human body, and an insulating outer surface member that covers the surface of the electrode that is not in close contact with the human body, and has an overall shape that is formed symmetrically, and a cut portion that opens to the left and right and is large enough for the neck of the person to be treated to pass through is formed in the center of the left and right. With this configuration, it is possible to use the ground potential conductor to pass suitable therapeutic electrons to a wide area to be treated, and to perform effective treatment safely.

[0013] Specifically, the subject can insert the neck or the like into the cut section and attach the ground potential conductor so as to cover the entire desired treatment area around the shoulder. This allows suitable treatment electrons to flow to the entire desired treatment area, such as the shoulder, neck, shoulder blade, and pectoral muscle. Therefore, even if the treatment area is large, it is possible to efficiently perform effective treatment on the entire treatment area without changing the attachment position of the ground potential conductor during treatment.

[0014] In the ground potential conductor of the present invention, the outer surface member may have a lower dielectric constant than the inner surface member. This prevents unintended flow of therapeutic electrons to a hand touching the outer surface of the ground potential conductor. This allows for safe and effective treatment in which therapeutic electrons are directed only to the area to be treated.

[0015] In the ground potential conductor of the present invention, the outer surface member may be thicker than the inner surface member, which prevents unintended flow of treatment electrons to a hand touching the outer surface of the ground potential conductor, thereby reducing the flow of treatment electrons to areas other than the treatment target area and allowing for safe and effective treatment.

[0016] In addition, in the ground potential conductor of the present invention, the inner surface member and the outer surface member may be formed to have different surface patterns, colors, or printing. This allows the user to easily distinguish between the inner surface of the ground potential conductor that is to be in contact with the human body and the outer surface that is not to be in contact with the human body. This makes it possible to prevent the ground potential conductor from being attached with the inner surface and the outer surface mistaken. This improves the usability of the ground potential conductor, and allows for safe and effective treatment with fewer attachment errors.

[0017] Furthermore, in the ground potential conductor of the present invention, the cut portion may be provided with a fastening member that closes a portion of the cut portion and connects the left and right sides. With this configuration, the left and right sides of the closed cut portion can be fixed with the fastening member, and the ground potential conductor can be easily attached to the area to be treated. This makes it easy to attach the ground potential conductor and provides an excellent therapeutic effect.

[0018] Furthermore, the ground potential conductor of the present invention may have a slit formed in the electrode to allow the electrode to be bent freely. With this configuration, the slit portion can be easily bent to allow the ground potential conductor to be in close contact with a wide area of ​​the human body, such as the back, shoulders, chest, ankles, heels, back of the foot, soles, etc. Therefore, suitable therapeutic electrons can be applied to a wide area of ​​the treatment target, allowing for effective treatment.

[0019] The electric potential therapy device of the present invention comprises a high-voltage transformer that boosts an input electric potential to generate a high-voltage output electric potential, a high-voltage lead that is connected to the high-voltage transformer and is in close contact with the human body to apply the output electric potential to the human body, and also comprises the above-mentioned ground electric potential lead of the present invention. With this configuration, it is possible to flow suitable therapeutic electrons to a desired wide range of treatment target areas, and to perform effective treatment efficiently and safely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, an electric potential therapeutic device 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 is a diagram showing a schematic configuration of an electric potential therapy device 1 according to an embodiment of the present invention. Referring to Fig. 1, the electric potential therapy device 1 is a device that performs electric potential therapy using an electric field by applying an AC output electric potential to a human body 30 of a person to be treated. The electric potential therapy device 1 is also a device that performs treatment by passing therapeutic electrons through the human body 30.

[0022] Specifically, the electric potential therapy device 1 comprises an electric potential output device 2 that generates a high electric potential, a high voltage lead 3 that is in close contact with the human body 30 and applies the high electric potential, a ground potential lead 4 that is in close contact with the human body 30 and applies a ground potential, and an insulating mat 5 that is placed under the human body 30.

[0023] The potential output device 2 is a device that generates an output potential for treatment. A high-voltage lead 3 that comes into contact with the human body 30 and applies a high-voltage output potential is connected to the potential output device 2, and a ground potential lead 4 that comes into close contact with the human body 30 and applies a ground potential is connected to the potential output device 2.

[0024] The potential output device 2 is provided with an output terminal 15 to which the high voltage lead 3 is connected, and a ground lead terminal 16 to which the ground potential lead 4 is connected. The high voltage lead 3 is detachably connected to the output terminal 15 of the potential output device 2 via a plug 19 and wiring 18, and the ground potential lead 4 is detachably connected to the ground lead terminal 16 of the potential output device 2 via a plug 28 and wiring 27.

[0025] The high-voltage lead 3 has a generally planar shape and is in close contact with the human body 30 directly or via clothing, etc. For example, the high-voltage lead 3 is placed on the seat of a chair 31 or the like like a cushion and is in close contact with the buttocks, etc. of a seated person to be treated. The high-voltage lead 3 may also be placed on the top surface of a bed (not shown) like a futon and used so as to be in close contact with the back, etc. of the person to be treated.

[0026] The high voltage lead 3 has a conductive electrode (not shown) to which the potential generated by the potential output device 2 is applied. The electrode is configured in a substantially planar shape. For example, the electrode may be formed from a flexible foil-like member made of copper, aluminum, or other conductive material. The electrode may also be formed from a flexible linear material made of a conductive material, or a combination of a flexible linear material and a foil-like material. The electrode may also be formed from a conductive cloth. The surface of the electrode may be covered with a sheet-like insulator (not shown) or the like.

[0027] The ground potential conductor 4 is a conductor that is attached to the human body 30 to which a high voltage is applied and that passes electrons for treatment, and is formed in a flexible, approximately planar shape and is attached to a desired treatment target part of the human body 30, such as the shoulder. The shape and configuration of the ground potential conductor 4 will be described later. The insulating mat 5 is an insulating mat on which the patient sits during treatment. The insulating mat 5 provides insulation between the human body 30 and the ground.

[0028] Fig. 2 is a circuit diagram showing a schematic configuration of the electric potential treatment device 1. Referring to Fig. 2, the electric potential output device 2 of the electric potential treatment device 1 has a power supply device 10 and a high-voltage transformer 11 that generates a high-voltage output potential from an input potential from the power supply device 10.

[0029] The power supply device 10 is a device that supplies AC power for electrical treatment to the primary side of a high-voltage transformer 11. The input side of the power supply device 10 is connected to an AC power source (not shown), and the output side is connected to the primary side of the high-voltage transformer 11. The power supply device 10 is a device that can change at least the voltage of the AC sent to the high-voltage transformer 11, and may include, for example, an inverter (not shown).

[0030] Specifically, the power supply device 10 may include a power supply circuit (not shown) that converts AC voltage from an AC power supply into a stable DC voltage that can be used by an inverter. The power supply circuit may include a filter circuit (not shown) for preventing electromagnetic interference, an overload protection circuit (not shown) that stops the operation of the power supply circuit when an abnormality such as an overload, overvoltage, or low voltage occurs, and the like.

[0031] The inverter of the power supply device 10 is connected to the output side of the power supply circuit, and converts the DC voltage supplied from the power supply circuit into AC of a predetermined voltage and outputs it. The inverter may be provided with an overcurrent protection circuit, a protective fuse, etc. (not shown) for stopping the output in the event of an abnormality.

[0032] High-voltage transformer 11 is a circuit that boosts an AC input potential to generate a high-voltage output potential. A current limiting resistor 13 that limits a short-circuit current or the like may be provided on the primary side or secondary side of high-voltage transformer 11. In addition, an impedance circuit (not shown) or the like that is connected in parallel to high-voltage transformer 11 may be provided on the secondary side of high-voltage transformer 11.

[0033] A high-voltage lead 3 is connected to one end of the secondary side of high-voltage transformer 11 via output terminal 15 and wiring 18. The circuit to which high-voltage lead 3 is connected may be provided with a semiconductor switch, a switch such as a relay, or other control circuit (not shown). High-voltage lead 3 is a circuit component that applies the output potential boosted by high-voltage transformer 11 to human body 30. As described above, high-voltage lead 3 is placed, for example, underneath human body 30 and is in close contact with human body 30. The other end of the secondary side of the high-voltage transformer 11 is indirectly grounded via a transfer resistor (not shown) or the like that is connected to a commercial power source (not shown).

[0034] The ground potential conductor 4 is grounded to a ground wiring 17 in the potential output device 2 via a wiring 27 and a ground conductor terminal 16, and is grounded via the ground wiring 17. The grounding of the ground wiring 17 may be in a form connected to, for example, a commercial wiring.

[0035] The ground wiring 17 may be provided with a protective resistor 14 and other current limiting circuits (not shown), switching circuits such as semiconductor switches and relays (not shown), and control circuits (not shown). The current limiting circuits, switching circuits, and control circuits may be controlled by a control device (not shown) based on operation commands from the user and detection results from various sensors.

[0036] The potential output device 2 is also provided with an operation unit, a display unit, various sensors, and a control device, all of which are not shown. The operation unit is a device through which the user inputs operation commands, and is connected to the control device, etc. The display unit displays various setting conditions such as the output potential, output current, frequency, timer, etc., as well as the output status, etc. As sensors, a temperature sensor that measures the body temperature of the user, a lead temperature sensor that measures the temperature of the high voltage lead 3 and the ground potential lead 4, a room temperature sensor that measures the room temperature, etc. may also be provided.

[0037] The control device is a device that executes a predetermined calculation based on input from the operation unit and various set values, etc., to control the power supply device 10 and switches (not shown) serving as switching means. Specifically, the control device performs output potential waveform control, timer control, display control, overload monitoring, voltage monitoring, etc. The power supply device 10 receives commands from the control device and generates a waveform of a predetermined voltage and frequency.

[0038] 1 and 2, when the high-voltage lead 3 is brought into close contact with the human body 30, a high voltage stepped up by the high-voltage transformer 11 is applied to the human body 30. When the ground potential lead 4 is brought into close contact with the desired treatment target area, the potential of the area to which the ground potential lead 4 is in close contact is lowered, providing a local potential gradient.

[0039] By using the high voltage lead 3 and the ground potential lead 4 for treatment in this way, suitable therapeutic electrons flow particularly near the treatment target area of ​​the human body 30 via the potential gradient generated between the high voltage lead 3 and the ground potential lead 4. This improves metabolism near the treatment target area, resulting in excellent therapeutic effects.

[0040] Fig. 3 is a front view showing a schematic diagram of the ground potential conductor 4. The front view is a view of the ground potential conductor 4 as seen from the side that contacts the patient, i.e., the inner surface 22. As shown in Fig. 3, the ground potential conductor 4 has an overall shape that is substantially symmetrical when viewed from the front.

[0041] Specifically, the ground potential conductor 4 has a substantially rectangular outer periphery with rounded corners. Each side of the outer periphery may be curved so as to be concave toward the center. The size of the ground potential conductor 4 may be, for example, about 40 cm×40 cm. That is, the approximate dimensions of the electrode 20 (see FIG. 4) are also, for example, about 40 cm×40 cm.

[0042] A cut portion 25 is formed in the left-right center of the ground potential conductor 4 when viewed from the front. The cut portion 25 is an opening that continues from approximately the center of the ground potential conductor 4 to the lower side, and is an opening that allows the ground potential conductor 4 to be opened by dividing it into left and right halves.

[0043] An opening of a size that allows the patient to pass the neck or the like by opening the cut portion 25 to the left and right is formed at the innermost part of the cut portion 25, i.e., approximately in the center of the ground potential conductor 4. That is, the patient can open the cut portion 25 to the left and right and pass the neck, arms, legs, ankles, etc.

[0044] In other words, the ground potential conductor 4 is a foldable pad formed into a generally butterfly shape that is symmetrical on both sides, and a cutout portion 25 is formed near the center on both sides into which the person to be treated can insert their neck, etc.

[0045] With this configuration, the patient can put the ground potential conductor 4 through the cut portion 25 around the neck, etc., and attach the ground potential conductor 4 so as to widely cover the area to be treated, for example, near the shoulders, etc. This allows the ground potential conductor 4 to be used to supply suitable therapeutic electrons to a wide area to be treated, allowing for effective and safe treatment.

[0046] In addition, since the area of ​​the ground potential conductor 4 is large, i.e., the area of ​​the electrode 20 is large, the impedance between the human body 30 (see FIG. 1) and the ground is reduced, and the potential difference between the electrode 20 of the ground potential conductor 4 and the human body 30 is reduced at the portion of the human body 30 where the ground potential conductor 4 is in close contact with the human body 30. This makes it possible to suppress the generation of ozone due to silent discharge.

[0047] The ground potential conductor 4 may also be provided with a fastening member 26. The fastening member 26 is, for example, a button, a hook-and-loop fastener, a zipper, a string, or the like, and is provided near the cut portion 25 or the peripheral edge of the ground potential conductor 4. This allows the ground potential conductor 4 to be in close contact with the human body 30 and firmly fixed. Therefore, there is no need to fix the ground potential conductor 4 with a separate fixing belt or the like, and the user does not need to keep holding the ground potential conductor 4 with his or her hand.

[0048] For example, a fastening member 26 may be provided near the lower portion of the cut portion 25 to close a part of the cut portion 25 and connect the left and right sides of the ground potential conductor 4. With this configuration, the left and right sides of the cut portion 25 that is closed after the neck or the like of the person to be treated is passed through can be fixed by the fastening member 26, and the ground potential conductor 4 can be easily brought into close contact with the part to be treated. This makes it easy to attach the ground potential conductor 4 and provides an excellent therapeutic effect.

[0049] For example, the fastening members 26 may be provided near the left and right edge portions of the upper and lower portions of the ground potential conductor 4. That is, the fastening members 26 may be provided so as to fix positions that correspond to the front and rear portions on the left and right sides of the human body 30 when the ground potential conductor 4 is folded and worn on the shoulder or the like of the human body 30. The fastening members 26 may also be provided in other portions so as to fix the vicinity of the outer peripheral end portion of the folded ground potential conductor 4 and other portions.

[0050] Thus, by providing the fastening member 26, the attachment of the ground potential lead 4 becomes easy, and the fit to the part to be treated becomes good, thereby improving the therapeutic effect. Furthermore, there is no need to provide a belt or the like for closely fixing the ground potential lead 4 to the human body 30, in addition to the ground potential lead 4. This makes it possible to reduce the number of accessories for attaching the ground potential lead 4, and in addition to the effect of making it easier to attach the ground potential lead 4, it is also advantageous in terms of productivity.

[0051] Fig. 4 is a cross-sectional view showing a schematic configuration of the ground potential conductor 4. Referring to Fig. 4, the ground potential conductor 4 has a conductive electrode 20, an insulating inner surface member 21 that covers the inner surface of the electrode 20, and an insulating outer surface member 23 that covers the outer surface of the electrode 20.

[0052] 3 and 4, the electrode 20 is configured in a generally planar, i.e., sheet-like, form having flexibility so as to be in close contact with the human body 30 (see FIG. 1) via the inner surface member 21, and is connected to wiring 27 (see FIG. 2), which in turn is connected to the potential output device 2.

[0053] For example, the electrode 20 may be formed from a flexible conductive cloth or the like. The electrode 20 may also be formed from a foldable foil-like member made of copper, aluminum, or other conductive material. The electrode 20 may also be formed from a flexible linear material made of a conductive material, or a combination of a flexible linear material and a foil-like material. The electrode 20 may also be formed such that a plurality of conductive sheet-like electrode 20 materials are dispersed and arranged in a bendable manner so as to constitute the electrode 20 in a predetermined region.

[0054] An inner surface member 21 that covers the electrode 20 is provided on the inner surface of the electrode 20, i.e., the surface that comes into close contact with the human body 30. The inner surface member 21 is a flexible sheet-like member made of an insulating material, and may be made of, for example, soft polyvinyl chloride resin or other synthetic resins. By making the inner surface member 21 from a flexible material in this way, the ground potential conductor 4 can be easily fitted to the human body 30. Furthermore, the electrode 20 may be formed with a number of slits in order to obtain flexibility.

[0055] An outer surface member 23 is provided on the outer surface of the electrode 20, i.e., the surface that is not in contact with the human body 30, to cover the electrode 20. The outer surface member 23 is a flexible sheet-like member made of an insulating material, and is made of an insulating material with a low dielectric constant, such as urethane foam.

[0056] The outer surface member 23 may be formed from a material having a lower dielectric constant than the inner surface member 21. This makes it possible to prevent unintended flow of therapeutic electrons due to unintended capacitive coupling occurring in a hand touching the outer surface 24 of the ground potential conductor 4. Therefore, suitable therapeutic electrons can be flowed only to the area to be treated from the inner surface member 21 side of the ground potential conductor 4, allowing safe and effective treatment.

[0057] Moreover, the outer surface member 23 may be formed so as to be less thick than the inner surface member 21. For example, the thickness dimension of the inner surface member 21 is 0.1 to 5 mm, preferably 0.5 to 3 mm, and more preferably 0.5 to 2 mm. If the clothing of the human body 30 is about 2 mm, the distance between the electrode 20 inside the ground potential conductor 4 and the human body 30 is, for example, about 3 mm.

[0058] On the other hand, the outer surface member 23 may be made of a material having a dielectric constant of 2 or less, and its thickness may be set to be thicker than the inner surface member 21, 2 to 30 mm, preferably 3 to 20 mm, and more preferably 5 to 20 mm.

[0059] For example, if the area of ​​the electrode 20 is 40 cm×40 cm and the dielectric constant between the ground potential conductor 4 and the human body 30 is 2, the capacitance of the electrode 20 on the inner member 21 side through a thickness of 3 mm is approximately 944 pF. In contrast, if the thickness of the outer member 23 is 15 mm and its dielectric constant is 1.5, the capacitance of the outer member 23 side is 141 pF. Therefore, even if the entire outer surface 24 of the ground potential conductor 4, i.e., the surface of the outer member 23 side that does not contact the treatment target part of the human body 30, is held down by hand, the shunt current flowing to the holding hand is at most approximately 13% of the total treatment current.

[0060] In other words, approximately 90% of the treatment current flows to the human body 30 via the inner surface member 21. In reality, the area held by the user's hand is 1 / 10 or less of the outer surface area of ​​the ground potential conductor 4, so nearly 100% of the current flows to the human body 30 via the inner surface member 21. Therefore, as described above, unintended treatment electrons are prevented from flowing to the hand holding the ground potential conductor 4 from the outer surface 24 side or to other structures in contact with the outer surface 24 side of the ground potential conductor 4.

[0061] In this way, by giving the outer surface member 23 and the inner surface member 21 different shapes, the inner surface 22 of the ground potential conductor 4, which is in close contact with the human body 30, and the outer surface 24, which is not in close contact with the human body 30, are differentiated, and capacitive coupling is obtained that efficiently flows therapeutic electrons only to the inner surface member 21 side that is in close contact with the human body 30.

[0062] In other words, the front-back structure with differentiated inner surface member 21 and outer surface member 23 can prevent unintended flow of therapeutic electrons to hands, etc., that touch outer surface 24 of ground potential conductor 4. This reduces therapeutic electrons that leak to areas other than the treatment target area, allowing suitable therapeutic electrons to flow only to the treatment target area, providing safe and effective treatment.

[0063] It is also possible to prevent the escape of treatment electrons to structures that are not the target area for treatment, such as the backrest of a chair 31 (see FIG. 1) with which the outer surface 24 of the ground potential conductor 4 comes into contact. This reduces the flow of unnecessary electrons and improves the efficiency of treatment.

[0064] The inner surface member 21 and the outer surface member 23 may be formed to have different surface patterns, colors, or printing. Specifically, the inside of the inner surface member 21, i.e., the inner surface 22, which is in close contact with the human body 30, and the outside of the outer surface member 23, i.e., the outer surface 24, which is not in close contact with the human body 30, may have different fabric textures, such as soft polyvinyl chloride resin or other synthetic resins, constituting the outer skin, and may have different appearances, textures, colors, etc. Furthermore, at least one of the inner surface 22 of the inner surface member 21 and the outer surface 24 of the outer surface member 23 may have printing or labels such as letters, symbols, marks, etc., indicating which surface it is.

[0065] In this way, by applying different patterns, colors, or printing, the user can easily distinguish between the inner surface 22 of the ground potential conductor 4 that is to be brought into contact with the human body 30 and the outer surface 24 that is not to be brought into contact with the human body 30. This makes it possible to prevent the ground potential conductor 4 from being attached by mistake, with the inner surface 22 being attached instead of the outer surface 24. This improves the ease of use of the ground potential conductor 4, enabling safe and effective treatment with fewer attachment errors.

[0066] Furthermore, the internal structure of the ground potential conductor 4, i.e., the electrode 20, the inner surface member 21, and the outer surface member 23, may be formed with slits (not shown) to allow the internal structure to bend freely. For example, the electrode 20 may be formed with a number of slits to provide flexibility. With this configuration, the ground potential conductor 4 can easily fit to the part of the human body 30 to be treated.

[0067] That is, by bending the slit portion, the ground potential conductor 4 can be brought into close contact with a wide area of ​​the human body 30, such as the back, shoulders, and chest. Also, by bending the slit portion, the ground potential conductor 4 can be brought into close contact with a wide area near the ankle, such as the ankle, heel, back of the foot, and sole of the foot. Therefore, suitable therapeutic electrons can be applied to a wide area to be treated, and effective treatment can be performed.

[0068] Next, with reference to Figs. 5 to 10, an example of use of the ground potential conductor attached to the human body 30 will be described in detail. 5 is a schematic diagram showing an example of use of the ground potential conductor 4, in which the ground potential conductor 4 is attached around the shoulder. As shown in FIG. 5, the ground potential conductor 4 is attached around the shoulder of the human body 30, and may be used for treating the trunk area around the neck.

[0069] For example, the subject can wear the ground potential conductor 4 so as to cover the entire desired treatment target area around the shoulders by inserting the neck or the like into the cut portion 25. In more detail, the ground potential conductor 4 may be formed and used in a substantially vest-like form worn by the subject. That is, the ground potential conductor 4 is formed in a substantially rectangular sheet shape, and the opening of the cut portion 25 formed in the substantially center of the ground potential conductor 4 is used as a collar through which the subject passes the neck.

[0070] The left and right sides of the cut portion 25 used as the collar portion, i.e., the approximately front-to-back central portion of the ground potential conductor 4, are folded so that the inner surface 22 of the front part of the ground potential conductor 4 faces the inner surface 22 of the rear part, and are used as a shoulder portion to be draped over the shoulder of the person to be treated. In other words, the front part of the folded ground potential conductor 4 is used as a front body part with the inner surface 22 coming into close contact with the chest, abdomen, etc. of the person to be treated, and the rear part is used as a back body part with the inner surface 22 coming into close contact with the back of the person to be treated.

[0071] Furthermore, the cut portion 25 formed in the front portion is used as an opening that opens to the left and right when the person being treated puts on or takes off the ground potential conductor 4. In other words, the front portion of the ground potential conductor 4 is separated and opened into a right front body and a left front body by the cut portion 25. The user can easily put on or take off the ground potential conductor 4 by opening the opening of the cut portion 25.

[0072] In addition, since the cut portion 25 is provided with a fastening member 26, the opening of the closed cut portion 25 can be fixed by the fastening member 26. That is, the right and left front portions of the ground potential conductor 4 can be connected and fixed by the fastening member 26, which can be a button, a hook-and-loop fastener, a zipper, a string, or the like.

[0073] In addition, the high-voltage lead 3 (see Figure 1) that applies a high-voltage output potential to the human body 30 may be placed, for example, on the seat of a chair 31 (see Figure 1) on which the person to be treated sits, and used so as to be in close contact with the buttocks, etc. of the human body 30.

[0074] In this way, the ground potential conductor 4 can be easily attached to cover the shoulders of the human body 30, and can supply suitable therapeutic electrons to the entire area of ​​the desired treatment target region, such as the shoulders, neck, shoulder blades, and pectoral muscles. Therefore, even if the treatment target region is large, effective treatment can be efficiently performed on the entire treatment target region without changing the attachment position of the ground potential conductor 4 during treatment.

[0075] Fig. 6 is a diagram showing another example of use of the ground potential conductor 4. Fig. 6 shows a schematic view of a human body 30 of a person to be treated seated on a chair 31 as seen from the back, and shows an example in which the ground potential conductor 4 is in intimate contact with the back of the person. As shown in Fig. 6, the ground potential conductor 4 may be used so as to be in intimate contact with the back of the human body 30. This allows treatment of the trunk area around the back.

[0076] At this time, since the left and right electrodes 20 (see FIG. 4) are separated at the cutout 25, the cutout 25 can be opened widely or closed narrowly to match the position of the shoulder of the human body 30. Therefore, the ground potential conductor 4 can be made to fit the human body 30 in a more three-dimensional shape.

[0077] Specifically, the ground potential conductor 4 may be used so as to be sandwiched between the back of the person to be treated and the backrest (not shown) of the chair 31 on which the person to be treated sits. This allows suitable therapeutic electrons to flow to the spine, shoulder blades, back, waist, etc. of the person to be treated, and allows effective treatment to be performed over a wide area around the back. The high voltage conductor 3 may be used so as to be in close contact with the buttocks, etc. of the human body 30.

[0078] Although not shown in the figures, the ground potential conductor 4 may be placed on the bed sheet or the like so as to be in close contact with the back of the person to be treated lying on a bed or the like, and may be sandwiched between the sleeping surface of the bed or the like and the human body 30. Even with such a method of use, the close contact of the ground potential conductor 4 allows a suitable treatment current to flow around the back, thereby performing treatment.

[0079] Fig. 7 is a diagram showing another example of use of the ground potential conductor 4, showing an example in which the ground potential conductor 4 is closely attached around the abdomen. As shown in Fig. 7, the ground potential conductor 4 may be used so as to be closely attached around the abdomen of the human body 30. This makes it possible to treat the trunk area around the abdomen.

[0080] Specifically, the ground potential conductor 4 may be used so that the inner surface 22 is in close contact with the abdomen, lower back, front thighs, etc. of the human body 30 of a person to be treated who is seated on a chair 31 or lying on a bed (not shown). The high voltage conductor 3 (see FIG. 1) may be used so as to be in close contact with, for example, the buttocks of the human body 30.

[0081] Even in this case, the cut portions 25 are formed so that the ground potential conductor 4 can three-dimensionally fit and adhere closely to the left and right feet. By using it in this way, therapeutic electrons can be suitably passed to the abdominal muscles, internal muscles, internal organs, etc. of the human body 30. This allows for effective treatment.

[0082] Fig. 8 is a diagram showing another example of use of the ground potential conductor 4, and shows an example in which the ground potential conductor 4 is used for treating peripheral parts such as the hand, arm, etc. As shown in Fig. 8, the ground potential conductor 4 may be used so that the inner surface 22 is in close contact with the hand, arm, etc. of the human body 30.

[0083] For example, the ground potential conductor 4 may be used so that the outer surface 24, i.e., the outer surface member 23 (see Figure 4) side, comes into contact with the abdomen, lower back, and front of the thighs of a human body 30 sitting on a chair 31, etc., or lying on a bed, etc. not shown. The hands, arms, etc. of the human body 30 are placed so as to be in close contact with the inner surface 22, i.e., the inner surface member 21 (see FIG. 4), of the ground potential conductor 4, whose outer surface 24 abuts against the abdomen, waist, front of the legs, etc. of the human body 30. The high voltage conductor 3 (see FIG. 1) may also be used so as to be in close contact with, for example, the buttocks of the human body 30.

[0084] By wearing it in this way, it is possible to provide suitable treatment by suitably passing therapeutic electrons to the arms, hands, fingers, upper arms, etc. of the human body 30. In other words, it is possible to pass a suitable therapeutic current from the trunk to the peripheral parts of the hands, which has the effect of alleviating inflammation in joints and inflamed areas.

[0085] In both the use example for treating the abdomen shown in Fig. 7 and the use example for treating the hands, arms, etc. shown in Fig. 8, the ground potential conductor 4 is used to be in close contact with the abdomen, waist, front of the thighs, etc. of the human body 30, and the attachment position of the ground potential conductor 4 is the same. However, in the use example shown in Fig. 7, the inner surface 22 of the ground potential conductor 4 is in close contact with the abdomen, etc., whereas in the use example shown in Fig. 8, the outer surface 24 of the ground potential conductor 4 is in close contact with the abdomen, etc., and the ground potential conductor 4 is attached upside down.

[0086] In a ground potential conductor 4 in which the inner surface member 21 on the inner surface 22 side of the ground potential conductor 4 and the outer surface member 23 on the outer surface 24 side are formed to different thicknesses, even if the ground potential conductor 4 is attached to the same position on the human body 30, by reversing the front and back of the ground potential conductor 4, it is possible to perform suitable treatment for different treatment target areas, as already explained.

[0087] Fig. 9 shows another example of use of the ground potential conductor 4, in which therapeutic electrons are applied to the thighs and knees. As shown in Fig. 9, the ground potential conductor 4 may be used such that the inner surface 22 is in close contact with the front of the thighs and the vicinity of the knees of the human body 30. The high voltage conductor 3 (see Fig. 1) is used such that it is in close contact with the buttocks, for example, of the human body 30. Even in such a use, since the cut portion 25 is formed, the ground potential conductor 4 fits three-dimensionally to the left and right legs even if the left and right legs are spread apart.

[0088] By using it in this manner, suitable therapeutic electrons can be supplied to the peripheral areas around the thigh and knee of the human body 30, and effective treatment can be performed over a wide area around the area where the ground potential conductor 4 is in close contact.

[0089] 10 is a diagram showing another example of use of the ground potential lead 4, in which the ground potential lead 4 is used for treatment around the ankle. As shown in Fig. 10, the ground potential lead 4 may be used so as to be in close contact with the area from the toes to the ankles of the human body 30.

[0090] Specifically, the ground potential conductor 4 is folded into a bag shape and worn around the ankles so that the inner surface 22 (see FIG. 3) fits closely to both the sole and dorsum of the foot of the human body 30. That is, the ground potential conductor 4 is worn so that the inner surface 22 fits closely to almost the entire surface of both feet from around the ankles to the heels, soles, dorsum and toes. At this time, since the cut portion 25 is formed in the ground potential conductor 4, the ground potential conductor 4 fits three-dimensionally to the surface of the area to be treated.

[0091] The ground potential conductor 4 worn so as to be in intimate contact with the ankle may be fixed by connecting opposing left and right portions or upper and lower portions of the folded ground potential conductor 4 with fasteners 26. The high voltage conductor 3 (see FIG. 1) is used so as to be in intimate contact with the human body 30, for example, the buttocks.

[0092] In this manner, the ground potential conductor 4 is attached so as to cover the entire area from the toes to the ankles of the human body 30 and to be in close contact with almost the entire surface, so that suitable therapeutic electrons can be supplied to the peripheral areas around the ankles of the human body 30, enabling effective treatment to be performed.

[0093] As described above, the electric potential therapy device 1 equipped with the ground potential conductor 4 according to this embodiment can supply suitable therapeutic electrons to a wide range of treatment target areas, enabling effective treatment to be performed efficiently and safely.

[0094] It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention. [Explanation of symbols]
