Description

Technical Field

[0001] The present invention relates to an electrotherapy device that performs potential therapy by applying a voltage to the human body or current therapy by passing an electric current through the human body.

Background Art

[0002] Conventionally, an electrotherapy device that performs treatment by applying an alternating high voltage to the human body is known. For example, Patent Document 1 discloses a potential therapy device that includes 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 alternating voltage of an arbitrary waveform, and a transformer that boosts the alternating voltage generated by the inverter to an output voltage, and transmits the output voltage boosted by the transformer to a conductor and applies it to the human body.

[0003] Also, in this type of electrotherapy device, it is known to locally lower the potential and give a potential gradient by using a conductor that locally discharges to the human body to which a high voltage potential is supplied, and to obtain a therapeutic effect by passing a therapeutic current. For example, Patent Document 2 discloses an electrode pad for high-voltage potential therapy used to locally discharge the high-voltage potential flowing into the body of a subject in potential therapy using a high-voltage potential therapy device.

[0004] Also, in this type of electrotherapy device, there is one in which a plurality of conductors are switchably connected. For example, Patent Document 3 discloses a potential therapy device including a plurality of high-voltage transformers that boost an input voltage to generate a high voltage, a head electrode, a seat electrode, and a back electrode to which the high voltage generated by the high-voltage transformer is applied. The same-phase voltage generated by the high-voltage transformer is applied to the seat electrode and the back electrode, and a changeover switch for turning on / off the generated high voltage is provided for the back electrode. By switching the changeover switch, the body potential of the subject is adjusted.

Patent Document 1

[0006] The above-described conventional electrotherapeutic apparatus had points that needed to be improved so that effective treatment could be performed efficiently. Specifically, in the conventional electrotherapeutic apparatus, a conductor is applied to an arbitrary treatment target site of the human body, and a high-voltage potential is supplied to the human body through the conductor to perform treatment. Therefore, in order to change the treatment target site and perform treatment, it was necessary to change the mounting position of the conductor and move the conductor each time.

[0007] For example, in the conventional technique disclosed in Patent Document 2, an electrode pad for high-voltage potential treatment can be attached to the human body to which a high potential is applied, and a treatment current can be locally passed to perform treatment. However, in such potential treatment using an electrode pad, it was difficult to pass suitable treatment electrons over a wide range. For example, it was not possible to pass suitable treatment electrons over a wide range from both shoulders to the back and perform treatment. Also, for example, when there are two treatment target sites, in the conventional treatment, it is not possible to treat the two sites simultaneously.

[0008] Therefore, in this type of electrotherapeutic apparatus, when performing treatment over a wide range, treatment may be performed by moving the electrode pad for high-voltage potential treatment. For example, the electrode pad is held by hand, peeled off from the treatment target site once, moved to another treatment target site, and pasted, or the electrode pad applied to the treatment target site is held by hand and moved while rubbing a wide treatment target site.

[0009] In addition, the potential treatment device disclosed in Patent Document 3 has a plurality of electrodes that can apply a high voltage of the same phase to the human body selectively or simultaneously. By switching a switch, the electrode area in contact with the human body can be changed to adjust the bioelectric potential of the subject. However, such a switch for turning on / off the high voltage was expensive, large-sized, and not easily installable.

[0010] Further, in the prior art disclosed in Patent Document 3, although the position where the high potential is applied can be switched by turning on / off the switch, the position of the ground potential cannot be automatically adjusted. Therefore, in order to suitably change the current flowing through a desired treatment target site, a ground potential conductor or the like for adjusting the position of the ground potential was separately used, and the user had to adjust the contact position of the ground potential conductor or the like.

[0011] The present invention has been made in view of the above circumstances, and an object thereof is to provide an electrotherapeutic apparatus capable of efficiently and effectively treating a plurality of treatment target sites without changing the mounting position of the conductor.

Means for Solving the Problems

[0012] The electrotherapeutic apparatus of the present invention includes a high-voltage transformer that boosts an input potential to generate a high-voltage output potential, and a high-voltage conductor connected to the secondary side of the high-voltage transformer that applies the output potential to the human body. A rectifier output circuit that divides the output potential into a positive electrode side and a negative electrode side is provided on the secondary side of the high-voltage transformer. The high-voltage conductor has a positive electrode side electrode to which the positive electrode side of the output potential divided by the rectifier output circuit is applied, and a negative electrode side electrode to which the negative electrode side of the output potential divided by the rectifier output circuit is applied.

[0013] In addition, the electrotherapy device of the present invention includes a high-voltage transformer that boosts an input potential to generate a high-voltage output potential, a high-voltage conductor connected to the secondary side of the high-voltage transformer that applies the output potential to the human body, and a grounding conductor that applies a ground potential to the human body. The grounding conductor has a positive-side grounding electrode and a negative-side grounding electrode. In the grounding circuit to which the grounding conductor is connected, a grounding conductor rectifying circuit is provided that divides the grounding circuit according to the flow direction of the grounding current. The grounding conductor rectifying circuit is provided with a positive-side grounding electrode rectifying circuit connected to the positive-side grounding electrode that reverses the flow direction of the current flowing toward the positive-side grounding electrode, and a negative-side grounding electrode rectifying circuit connected to the negative-side grounding electrode that makes the flow direction of the current flowing toward the negative-side grounding electrode the positive direction.

Advantages of the Invention

[0014] The electrotherapy device of the present invention includes a high-voltage transformer that boosts an input potential to generate a high-voltage output potential, and a high-voltage conductor connected to the secondary side of the high-voltage transformer that applies the output potential to the human body. A rectifying output circuit that divides the output potential into a positive side and a negative side is provided on the secondary side of the high-voltage transformer. The high-voltage conductor has a positive-side electrode to which the positive side of the output potential divided by the rectifying output circuit is applied, and a negative-side electrode to which the negative side of the output potential divided by the rectifying output circuit is applied. Thereby, it is possible to efficiently and effectively treat a plurality of treatment target sites without changing the mounting position of the high-voltage conductor.

[0015] Specifically, for example, by changing the levels and periods of the positive and negative waveforms as waveforms selectively containing high-frequency components on the positive electrode side, negative electrode side, or both electrodes, the coupling impedance of the capacitance between the human body and the electrode or the potential to the human body can be intentionally controlled. As a result, the site where the therapeutic current easily flows to the human body can be controlled. Thereby, a positive therapeutic current can flow from the positive electrode side electrode to the treatment target site where the positive electrode side electrode is attached, and a negative therapeutic current can flow from the negative electrode side electrode to another treatment target site where the negative electrode side electrode is attached. In this way, without changing the attachment of the high-voltage conductor, the therapeutic current and potential can be individually supplied to two treatment target sites distinguished by the positive electrode side electrode and the negative electrode side electrode with different contact positions.

[0016] Further, the electrotherapy device of the present invention has a high-voltage conductor grounding circuit connected to the high-voltage conductor. The high-voltage conductor grounding circuit may be provided with a positive electrode side grounding rectifying circuit connected to the positive electrode side electrode and having the flowing direction of the current toward the positive electrode side electrode as the positive direction, and a negative electrode side grounding rectifying circuit connected to the negative electrode side electrode and having the flowing direction of the current toward the negative electrode side electrode as the reverse direction. Thereby, a grounding current can flow through the high-voltage conductor grounding circuit, and one of the positive electrode side electrode and the negative electrode side electrode can be used as a grounded conductor to perform effective electrotherapy.

[0017] Specifically, due to the provision of the high-voltage conductor grounding circuit, when the output potential is applied to the positive electrode side electrode, the negative electrode side electrode is grounded, and when the output potential is applied to the negative electrode side electrode, the positive electrode side electrode is grounded. Therefore, electrotherapy can be performed in which the treatment in which the therapeutic current flows with the positive electrode side electrode as the high-voltage conductor and the negative electrode side electrode as the grounded conductor, and the treatment in which the therapeutic current flows with the positive electrode side electrode as the grounded conductor and the negative electrode side electrode as the high-voltage conductor are sequentially switched and executed at the timing when the positive and negative of the output potential change. Thereby, since a positive and negative intended grounding circuit is provided for the treatment target sites where the positive electrode side electrode and the negative electrode side electrode are attached, a large therapeutic current can be stably flowed for each site, and the therapeutic effect can be improved.

[0018] Further, in the electrotherapy device of the present invention, a ground impedance circuit for controlling the ground current may be provided in the high-voltage conductor ground circuit. Thereby, the divided voltage value of the output potential applied to the human body can be lowered, and a large therapeutic current can flow through a stable ground circuit, and the voltage and therapeutic current applied to the human body can be suitably controlled.

[0019] Further, in the electrotherapy device of the present invention, at least one of the positive electrode side electrode and the negative electrode side electrode may be provided in plurality so as to be able to apply the output potential to different treatment target sites of the human body. Thereby, without removing the high-voltage conductor from the human body and moving it to change the mounting position, a plurality of treatment target sites at different positions can be suitably treated.

[0020] Further, in the electrotherapy device of the present invention, the positive electrode side electrode and the negative electrode side electrode may be integrated so as to constitute one of the high-voltage conductors. The high-voltage conductor can be easily attached to, removed from, tidied up, and organized on the human body, and a plurality of treatment target sites can be efficiently treated without moving the high-voltage conductor.

[0021] Further, the electrotherapy device of the present invention includes a ground conductor for applying a ground potential to the human body. The ground conductor has a positive electrode side ground electrode and a negative electrode side ground electrode. In the ground circuit to which the ground conductor is connected, a ground conductor rectifying circuit for dividing the ground circuit according to the flowing direction of the ground current is provided. In the ground conductor rectifying circuit, a positive electrode side ground electrode rectifying circuit connected to the positive electrode side ground electrode and reversing the flowing direction of the current flowing toward the positive electrode side ground electrode, and a negative electrode side ground electrode rectifying circuit connected to the negative electrode side ground electrode and setting the flowing direction of the current flowing toward the negative electrode side ground electrode as the positive direction may be provided. Thereby, without changing the mounting position of the high-voltage conductor, a plurality of treatment target sites where the positive electrode side ground electrode and the negative electrode side ground electrode are mounted can be efficiently and effectively treated.

[0022] In addition, the electrotherapeutic apparatus of the present invention has a waveform control device that generates the waveform of the output potential in an arbitrary shape, and the waveform control device may control the output potential so that the positive and negative sides of the output potential have an asymmetric waveform. Thereby, the waveform shape of the output potential, that is, the frequency, voltage, period, etc., can be changed between the treatment target site where the positive electrode side is attached and the treatment countermeasure site where the negative electrode side is attached, and the physical sensation or treatment effect by the treatment current can be suitably adjusted. Further, by inverting the positive and negative waveforms with different waveforms, it is possible to change the physical sensation and adjust the treatment effect as if the high-voltage conductor has been moved without moving the high-voltage conductor.

[0023] In addition, in the electrotherapeutic apparatus of the present invention, the high-voltage conductor and the ground conductor may be integrated so as to constitute one conductor unit. According to the conductor unit in which the high-voltage conductor and the ground conductor are integrated in this way, it is possible to suitably treat a plurality of treatment target sites without changing the mounting position, and it is possible to easily mount, remove, store, or organize the high-voltage conductor and the ground conductor on the human body.

DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, the electrotherapy device 1 according to the embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a circuit diagram showing a schematic configuration of the electrotherapy device 1 according to the embodiment of the present invention. Referring to FIG. 1, the electrotherapy device 1 is a device that applies an alternating output potential to the human body 70 to perform potential therapy or current therapy using an electric field. Further, the electrotherapy device 1 is a device that supports passing a therapeutic current through the human body 70 to improve metabolism, promote the repair of fractures, injuries, inflammation, etc., and improve the physical condition. The electrotherapy device 1 may be used, for example, after surgery, during illness, or after illness, and is installed and used on a hospital bed, chair, etc. at home.

[0026] The electrotherapy device 1 includes a main body unit 2 that generates a high-voltage output potential for treatment, and a high-voltage conductor 3 that is connected to the main body unit 2 and applies the output potential and current supplied from the main body unit 2 to the human body 70.

[0027] The main unit 2 of the electrotherapy device 1 includes a power supply device 10, a high-voltage transformer 11 that generates a high-voltage output potential from the input potential from the power supply device 10, and a rectifier output circuit 13 that rectifies the output potential boosted by the high-voltage transformer 11.

[0028] The power supply device 10 is a device that is connected to an AC power supply (not shown) and supplies AC power for electrotherapy 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, for example, to 0 - 24V, and may be provided with an inverter (not shown) or the like. Also, a battery power supply (not shown) may be used as the power supply of the power supply device 10.

[0029] Specifically, the power supply device 10 may be provided with a power supply circuit (not shown) that converts the AC voltage from the AC power supply into a stable DC voltage that can be used by the inverter. The power supply circuit may be provided with a filter circuit (not shown) for countermeasures against interfering electromagnetic waves, an overload protection circuit (not shown) that stops the operation of the power supply circuit in case of abnormalities such as overload, overvoltage, or low voltage, etc.

[0030] 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. Note that the inverter may be provided with an overcurrent protection circuit (not shown) or a protection fuse for stopping the output in case of abnormalities.

[0031] The high-voltage transformer 11 is a circuit that boosts the AC input potential to generate a high-voltage output potential. A primary-side current limiting resistor (not shown) for limiting the short-circuit current may be provided on the primary side of the high-voltage transformer 11.

[0032] One end of the secondary side of the high-voltage transformer 11 is connected to the high-voltage conductor 3 via the rectifier output circuit 13, the output terminal 16, and the output wiring 19. A current limiting resistor 12 for limiting the short-circuit current may be provided on one end side of the secondary side of the high-voltage transformer 11.

[0033] The other end of the secondary side of the high-voltage transformer 11 is grounded to the grounding wire 30 via the shunt resistor 29. That is, when the electrotherapeutic device 1 is used as a potential therapeutic device, it is necessary to ground the low-voltage side among the outputs of the secondary side of the high-voltage transformer 11 for safety. The grounding wire 30 may be, for example, the wiring on the ground side of the commercial power supply. Note that the grounding wire 30 is unnecessary if there is no safety problem.

[0034] The rectifying output circuit 13 is a circuit that divides the output potential boosted by the high-voltage transformer 11 and applied to the high-voltage conductor 3 into a positive electrode side and a negative electrode side. Specifically, in the rectifying output circuit 13, a positive electrode side diode 14 that sets the flow direction of the current toward the high-voltage conductor 3 as the positive direction and a negative electrode side diode 15 that sets the flow direction of the current toward the high-voltage conductor 3 as the reverse direction are provided in parallel.

[0035] The high-voltage conductor 3 is a conductor that applies the output potential boosted by the high-voltage transformer 11 and rectified by the rectifying output circuit 13 to the human body 70. Specifically, the high-voltage conductor 3 is a sheet-like circuit member that is attached to the treatment target site of the human body 70 and is flexibly formed so as to conform closely to the outer shape of the treatment target site of the human body 70.

[0036] The high-voltage conductor 3 is provided with a positive electrode side electrode 22 to which the positive electrode side of the output potential divided by the rectifying output circuit 13 is applied, and a negative electrode side electrode 23 to which the negative electrode side of the output potential divided by the rectifying output circuit 13 is applied.

[0037] The positive electrode side electrode 22 is connected to the positive electrode side diode 14 via the positive electrode side terminal 17 and the positive electrode side wiring 20, and the negative electrode side electrode 23 is connected to the negative electrode side diode 15 via the negative electrode side terminal 18 and the negative electrode side wiring 21.

[0038] With such a configuration, it is possible to efficiently and effectively treat a plurality of treatment target sites on the human body 70 without removing the high-voltage conductor 3 from the human body 70 and changing the mounting position. Specifically, a positive treatment current can flow from the positive electrode side electrode 22 to the treatment target site where the positive electrode side electrode 22 is mounted through the human body capacitance C1. And to another treatment target site where the negative electrode side electrode 23 is mounted, a negative treatment current can flow from the negative electrode side electrode 23 through the human body capacitance C2.

[0039] In this way, for two treatment target sites distinguished by the positive electrode side electrode 22 and the negative electrode side electrode 23 with different contact positions, suitable treatment currents can be passed respectively without changing the mounting of the high-voltage conductor 3.

[0040] For example, the energization locations of the treatment current can be divided into two locations, the upper body and the lower body centered on the torso, and suitable currents can be passed. Thereby, without changing the position of the high-voltage conductor 3, the torso part can be suitably treated evenly.

[0041] Also, for example, by making the output waveform into a positive half-wave, a negative half-wave or a waveform including high-frequency components on both the positive and negative electrode sides, the impedance of the human body capacitance C1 or the human body capacitance C2 changes, and the current flowing through the high-voltage conductor 3 can be adjusted.

[0042] In addition, the electrotherapy device 1 is provided with an operation unit, a display unit, various sensors or a control device (not shown), etc. The operation unit is a device for the user to input operation commands and is connected to the control device, etc. The display unit displays various setting conditions or output status such as output potential, output current, frequency, timer, etc. As the sensors, a temperature sensor for measuring the user's body temperature, a conductor temperature sensor for measuring the temperature of the high-voltage conductor 3, a room temperature sensor for measuring the indoor air temperature, etc. may be provided.

[0043] The control device is a device that executes a predetermined calculation based on the input of the operation unit or various set values, etc., and controls the power supply device 10 or various switches (not shown) serving as switching means. Specifically, the control device performs switching control of the high-voltage conductor 3, waveform control of the output potential, timer control, display control, overload monitoring, voltage monitoring, etc. The power supply device 10 receives a command from the control device and outputs a waveform of a predetermined voltage and frequency. The switches are switched in response to a command from the control device.

[0044] Also, a discharge resistor 26 grounded for discharging the charge of the charged high-voltage conductor 3 may be connected to the circuit connecting the rectifier output circuit 13 and the high-voltage conductor 3. Specifically, the circuit connecting the positive-side diode 14 and the positive-side electrode 22 may be connected to the ground wiring 30 via the positive-side discharge resistor 26 and the transfer resistor 29. Also, the circuit connecting the negative-side diode 15 and the negative-side electrode 23 may be connected to the ground wiring 30 via the negative-side discharge resistor 27 and the transfer resistor 29.

[0045] Reverse current prevention circuits 24 and 25 for preventing reverse current may be connected to the discharge resistor 26 and the discharge resistor 27, respectively. The reverse current prevention circuits 24 and 25 are, for example, diodes. Specifically, the positive-side reverse current prevention circuit 24 connected to the high-voltage conductor 3 side of the positive-side diode 14 reverses the flow direction of the current flowing toward the positive-side diode 14 and the positive-side electrode 22. The negative-side reverse current prevention circuit 25 connected to the high-voltage conductor 3 side of the negative-side diode 15 makes the flow direction of the current flowing toward the negative-side diode 15 and the negative-side electrode 23 the positive direction. Thereby, the charge charged in the high-voltage conductor 3 is discharged appropriately, so that it is possible to suppress the high-voltage conductor 3 from being charged with direct current.

[0046] Also, instead of or in addition to the discharge resistors 26 and 27 and the reverse current prevention circuits 24 and 25, a discharge resistor 28 for discharging charge may be provided. For example, the discharge resistor 28 is provided so as to connect the positive-side circuit connecting the positive-side diode 14 and the positive-side electrode 22 and the negative-side circuit connecting the negative-side diode 15 and the negative-side electrode 23.

[0047] Further, the rectifier output circuit 13 may be provided with a switch (not shown) that selectively shorts the positive electrode side diode 14 and the negative electrode side diode 15. By providing such a switch, for example, by switching the switch by a control device (not shown), the high-voltage conductor 3 can be used as a normal conductor to which a normal AC potential that has not been rectified by the positive electrode side diode 14 and the negative electrode side diode 15 is applied.

[0048] Also, the rectifier output circuit 13 may be provided with a polarity inversion circuit (not shown) that selectively inverts the rectification polarities of the positive electrode side diode 14 and the negative electrode side diode 15. Thereby, without removing the high-voltage conductor 3 and changing the mounting position, the parts to which the output potential on the positive electrode side and the output potential on the negative electrode side are applied can be inverted, and excellent electrotherapy can be performed, giving the feeling as if the high-voltage conductor 3 has been moved.

[0049] Next, with reference to FIGS. 2 to 13, an example in which the embodiment of the electrotherapy device 1 is modified will be described in detail. Components that have the same or similar operations and effects as those of the embodiment already described are denoted by the same reference numerals, and the description thereof will be omitted.

[0050] FIG. 2 is a circuit diagram showing a schematic configuration of the electrotherapy device 1 according to another embodiment of the present invention. Referring to FIG. 2, the rectifier output circuit 13 may be provided on the high-voltage conductor 3 side. That is, the positive electrode side diode 14 and the negative electrode side diode 15 may be provided outside the main body unit 2 and in the vicinity of the positive electrode side electrode 22 and the negative electrode side electrode 23 that constitute the high-voltage conductor 3.

[0051] Although details will be described later, the high-voltage conductor 3 may be formed in a flexible sheet shape integrating the positive electrode side electrode 22 and the negative electrode side electrode 23.

[0052] The rectifier output circuit 13 is connected to the current limiting resistor 12 via the output wiring 19 and the output terminal 16, and is connected to the secondary side of the high-voltage transformer 11. With such a configuration, the user can connect and use the high-voltage conductor 3 to the main body unit 2 by simply connecting one output wiring 19 to one output terminal 16. The connection between the output wiring 19 and the output terminal 16 only requires inserting the plug of the output wiring 19 into the socket as the output terminal 16. Therefore, the user can easily connect and disconnect the high-voltage conductor 3.

[0053] Also, the plug of the output wiring 19 may be formed to be insertable into the output terminal socket of a prior art electrotherapy device. Thereby, the high-voltage conductor 3 having the positive electrode side electrode 22 and the negative electrode side electrode 23 can be connected to and used with the prior art electrotherapy device.

[0054] Also, the discharge resistor 28 for charge discharge may be provided to connect the positive electrode side circuit connecting the positive electrode side diode 14 and the positive electrode side electrode 22 and the negative electrode side circuit connecting the negative electrode side diode 15 and the negative electrode side electrode 23.

[0055] FIG. 3(A) is a perspective view showing an example of the positive electrode side electrode 22 and the negative electrode side electrode 23 of the high-voltage conductor 3, and FIG. 3(B) is a perspective view showing another example of the positive electrode side electrode 22 and the negative electrode side electrode 23. Referring to FIG. 3(A), the positive electrode side electrode 22 and the negative electrode side electrode 23 are formed in a flexible sheet shape having flexibility that easily conforms to the unevenness of the surface of the human body 70 (see FIG. 1).

[0056] Also, the positive electrode side electrode 22 and the negative electrode side electrode 23 formed in a sheet shape may be formed in a mesh shape with a plurality of through holes. By forming the positive electrode side electrode 22 and the negative electrode side electrode 23 in a mesh shape, the flexibility of the high-voltage conductor 3 is improved, and it becomes easier to conform to the unevenness of the surface of the human body 70.

[0057] As shown in Fig. 3(B), the positive electrode side electrode 22 and the negative electrode side electrode 23 may be formed from a flexible covered wire or the like having flexibility. The covered wire may be folded back in a substantially U shape to the left and right and arranged in a plurality in parallel. Even with such a configuration, a high-performance high-voltage conductor 3 that fits the treatment target site of the human body 70 can be obtained.

[0058] Fig. 4 is a circuit diagram showing a schematic configuration of an electrotherapy device 1 according to another embodiment of the present invention. Referring to Fig. 4, the electrotherapy device 1 may have a high-voltage conductor grounding circuit 31 connected to the high-voltage conductor 3.

[0059] The high-voltage conductor grounding circuit 31 may be provided with a positive electrode side grounding rectifying circuit 32 connected to the positive electrode side electrode 22 and a negative electrode side grounding rectifying circuit 33 connected to the negative electrode side electrode 23.

[0060] The positive electrode side grounding rectifying circuit 32 is, for example, a diode circuit that is connected to the positive electrode side electrode 22 and sets the flowing direction of the current toward the positive electrode side electrode 22 as the positive direction. The negative electrode side grounding rectifying circuit 33 is, for example, a diode circuit that is connected to the negative electrode side electrode 23 and sets the flowing direction of the current toward the negative electrode side electrode 23 as the reverse direction.

[0061] By providing such a high-voltage conductor grounding circuit 31, a grounding current can flow from the high-voltage conductor 3 through the high-voltage conductor grounding circuit 31, and it can be used as a conductor for grounding one of the positive electrode side electrode 22 and the negative electrode side electrode 23, enabling effective electrotherapy.

[0062] Specifically, due to the provision of the high-voltage conductor grounding circuit 31, when the output potential is applied to the positive electrode side electrode 22, the negative electrode side electrode 23 is grounded, and when the output potential is applied to the negative electrode side electrode 23, the positive electrode side electrode 22 is grounded. Thereby, a suitable treatment current can flow from the positive electrode side electrode 22 through the human body capacitance C1, the human body 70, and the human body capacitance C2 to the negative electrode side electrode 23.

[0063] Therefore, it is possible to perform electrotherapy in which the treatment in which a treatment current flows with the positive electrode side electrode 22 as a high-voltage conductor and the negative electrode side electrode 23 as a grounded conductor, and the treatment in which a treatment current flows with the positive electrode side electrode 22 as a grounded conductor and the negative electrode side electrode 23 as a high-voltage conductor are sequentially switched at the timing when the positive and negative of the output potential change. As a result, a large treatment current can be stably passed through the treatment target site to which the positive electrode side electrode 22 and the negative electrode side electrode 23 are attached, and the treatment effect can be improved.

[0064] Further, the high-voltage conductor grounding circuit 31 may be provided with a grounding impedance circuit 34 for controlling the grounding current. The grounding impedance circuit 34 is a circuit composed of, for example, a resistor, a capacitor, or a CR circuit combining these, which is not shown in the figure. The grounding impedance circuit 34 may be configured such that the positive electrode side grounding rectifying circuit 32 and the negative electrode side grounding rectifying circuit 33 have different impedances.

[0065] By providing such a grounding impedance circuit 34, the divided voltage value of the output potential applied to the human body 70 can be lowered, and a large treatment current can be passed, and an appropriate voltage and treatment current that do not become excessive to the human body 70 can be preferably controlled.

[0066] Further, the grounding impedance circuit 34 may be provided with a switch 35 that can be switched ON / OFF by a control device (not shown). The switch 35 may be configured to be selectively switched ON / OFF for only one of the positive electrode side grounding rectifying circuit 32 and the negative electrode side grounding rectifying circuit 33.

[0067] In the electrotherapy device 1 having such a configuration, the rectifier output circuit 13 may also be provided with a switch (not shown) that selectively short-circuits the positive electrode side diode 14 or the negative electrode side diode 15. Further, the rectifier output circuit 13 may be provided with a polarity inversion circuit (not shown) that selectively inverts the rectification polarities of the positive electrode side diode 14 and the negative electrode side diode 15.

[0068] Referring to FIGS. 1 and 4, a reverse current prevention circuit 24 and a discharge resistor 26 with a rectification polarity opposite to that of the positive electrode side ground rectification circuit 32 may be provided in parallel to the positive electrode side ground rectification circuit 32 of the high voltage conductor ground circuit 31. Also, a reverse current prevention circuit 25 and a discharge resistor 27 with a rectification polarity opposite to that of the negative electrode side ground rectification circuit 33 may be provided in the negative electrode side ground rectification circuit 33 of the high voltage conductor ground circuit 31.

[0069] FIG. 5 is a circuit diagram showing a schematic configuration of an electrotherapeutic apparatus 1 according to another embodiment of the present invention. Referring to FIG. 5, the high voltage conductor ground circuit 31 may be provided with a plurality of ground impedance circuits 34, 36, 37 or capacitors 38 that can be selectively connected.

[0070] Switches 39, 40, 41, 42 may be provided in parallel to the plurality of ground impedance circuits 34, 36, 37 or capacitors 38, respectively. The switches 39, 40, 41, 42 are controlled to be ON / OFF by a control device (not shown), and selectively short-circuit the ground impedance circuits 34, 36, 37 or capacitors 38.

[0071] By providing a plurality of ground impedance circuits 34, 36, 37 or capacitors 38 that can be selectively switched and connected in this way, the voltage division value of the output potential applied to the human body 70 can be suitably controlled, and a suitable therapeutic current can be passed. Also, by suitably lowering the output potential applied to the human body 70, an effect of alleviating the electric shock that occurs when an external person touches the human body 70 of the subject of the electrotherapeutic apparatus 1 can be obtained.

[0072] FIG. 6(A) is a diagram showing the waveform 43 of the output potential of the electrotherapeutic apparatus 1 according to another embodiment of the present invention. FIG. 6(B) is a diagram showing the waveform 44 of the output potential applied to the positive electrode side electrode 22, and FIG. 6(C) is a diagram showing the waveform 45 of the output potential applied to the negative electrode side electrode 23.

[0073] The control device (not shown) of the electrotherapy device 1 has a function as a waveform control device that generates the waveform 43 of the output potential in an arbitrary shape. That is, the electrotherapy device 1 is controlled by a control device as a waveform control device and can generate an output potential with an arbitrary waveform.

[0074] For example, as shown in FIG. 6(A), the waveform control device may control the waveform 43 of the output potential so that the waveform 44 on the positive electrode side and the waveform 45 on the negative electrode side of the output potential are asymmetric. As a result, the output potential applied to the positive electrode 22 (see FIG. 1) becomes the waveform 44 on the positive electrode side as shown in FIG. 6(B), and the output potential applied to the negative electrode 23 (see FIG. 1) becomes the waveform 45 on the negative electrode side in a form different from the waveform 44 of the output potential applied to the positive electrode 22 as shown in FIG. 6(C).

[0075] In this way, the shape of the waveform 43 of the output potential, that is, the frequency, voltage, period, etc., can be changed between the treatment target site where the positive electrode 22 is attached and the treatment target site where the negative electrode 23 is attached, and the physical sensation or treatment effect by the treatment current can be suitably adjusted. Further, by inverting the positive and negative waveforms 44 and 45 with different shapes, it is possible to change the physical sensation and adjust the treatment effect as if the high-voltage conductor 3 (see FIG. 1) has been moved without moving the high-voltage conductor 3.

[0076] Note that the output potential may be controlled and generated so that the areas of the waveform 44 on the positive electrode side and the waveform 45 on the negative electrode side are the same. Thereby, it is possible to prevent saturation from occurring in the high-voltage transformer 11.

[0077] FIG. 7(A) is a diagram showing the high-voltage conductor 3 according to another embodiment of the present invention, FIG. 7(B) is another example of the high-voltage conductor 3, and FIG. 7(C) is still another example of the high-voltage conductor 3. Referring to FIG. 7(A), at least one of the positive electrode 22 and the negative electrode 23 may be provided in plurality so as to be able to apply an output potential to different treatment target sites of the human body 70. Thereby, it is possible to suitably treat a plurality of treatment target sites at different positions without removing the high-voltage conductor 3 from the human body 70, moving it, and changing the mounting position.

[0078] For example, two positive electrode side electrodes 22 and two negative electrode side electrodes 23 may be provided and mounted on the human body 70 such that the positive and negative of the high-voltage conductor 3 alternate. With such mounting, for example, a therapeutic current can be passed through substantially the entire body of the human body 70.

[0079] Also, as shown in FIG. 7(B), the positive electrode side electrode 22 and the negative electrode side electrode 23 may be mounted on the human body 70 such that, for example, one of the opposing sides is formed in an uneven shape and the two unevenly formed sides substantially mesh with each other. Even with such a configuration, a suitable therapeutic current can be passed through a desired treatment target site of the human body 70.

[0080] Also, as shown in FIG. 7(C), the high-voltage conductor 3 may be composed of, for example, a positive electrode side electrode 22 mounted substantially at the center of the human body 70 and a negative electrode side electrode 23 mounted so as to surround the outer periphery of the positive electrode side electrode 22. That is, a space portion is formed in the central portion of the negative electrode side electrode 23 so as to penetrate and accommodate the positive electrode side electrode 22, and the positive electrode side electrode 22 is mounted in the space portion. With such a high-voltage conductor 3, potential therapy can be performed to pass a suitable therapeutic current from the trunk portion to the erasure portion of the human body 70.

[0081] FIG. 8(A) is a plan view of a high-voltage conductor 3 according to another embodiment of the present invention, and FIG. 8(B) is a cross-sectional view of the high-voltage conductor 3. As shown in FIG. 8(A), the positive electrode side electrode 22 and the negative electrode side electrode 23 may be integrated to form one high-voltage conductor 3.

[0082] Specifically, as shown in FIG. 8(B), the positive electrode side electrode 22 and the negative electrode side electrode 23 are arranged and placed side by side on the upper surface of a common opposite-side insulating material 47, and a common human-body side insulating material 46 is provided on the upper surfaces of the positive electrode side electrode 22 and the negative electrode side electrode 23. That is, the positive electrode side electrode 22 and the negative electrode side electrode 23 are integrally formed by being sandwiched between a pair of human-body side insulating materials 46 and an opposite-side insulating material 47.

[0083] The human body side insulating material 46 is formed of a synthetic resin material such as urethane foam having a dielectric constant of about 1.5, and constitutes the surface on the side that is in close contact with the human body 70 of the high-voltage conductor 3. The opposite side insulating material 47 is formed of a synthetic resin material such as urethane foam having a dielectric constant of about 1.5, becomes the surface on the opposite side to the human body 70, and abuts on the floor surface, futon, etc. on which the high-voltage conductor 3 is placed.

[0084] With such an integrated configuration, it is possible to easily perform operations such as attaching, detaching, tidying up, and organizing the high-voltage conductor 3 to / from the human body 70. And as described above, it is possible to efficiently treat a plurality of treatment target sites without moving the high-voltage conductor 3.

[0085] Here, the planar size of the integrated high-voltage conductor 3, that is, the dimension W×dimension L shown in Fig. 8(A) is, for example, about 30 cm×120 cm to about 100 cm×200 cm. With such a size, it is possible to select substantially the entire body of the human body 70 as the treatment target site and perform suitable treatment. Thereby, even if the high-voltage conductor 3 is laid on a floor at ground potential, for example, it is possible to reduce the influence such as leakage of the treatment current due to the capacitance with the ground.

[0086] Also, it is desirable that the planar size, that is, the area of each of the positive electrode side electrode 22 and the negative electrode side electrode 23 is substantially the same. Even if the areas of the positive electrode side electrode 22 and the negative electrode side electrode 23 are not the same, it is desirable that one area is from 1 / 2 to 2 times the other area. That is, the surface area ratio of the positive electrode side electrode 22 and the negative electrode side electrode 23 is from 2:1 to 1:2.

[0087] By making the area ratio of the positive electrode side electrode 22 and the negative electrode side electrode 23 approach about 1:1, in the case of flowing a treatment current by grounding either the positive electrode side electrode 22 or the negative electrode side electrode 23, it is possible to make the ground currents flowing to the grounded side substantially equal. When the user wears the high-voltage conductor 3, the high-voltage conductor 3 can be worn in the correct direction without being conscious of the flow of the treatment current and the direction of the high-voltage conductor 3.

[0088] In addition, since the areas of the positive electrode side electrode 22 and the negative electrode side electrode 23 are substantially the same, the potential of the human body 70 is equally divided and reduced by the positive electrode side electrode 22 and the negative electrode side electrode 23, so that the effect of alleviating the electric shock generated when an external person or the like comes into contact with the human body 70 of the subject can also be obtained.

[0089] In addition, a configuration in which the area ratio of the positive electrode side electrode 22 to the negative electrode side electrode 23 is 1:2 is also effective in a treatment method or the like that attenuates the voltage only on the positive electrode side. That is, the human body capacitance C1 (see FIG. 1) between the positive electrode side electrode 22 and the human body 70 is reduced, and the ground current from the positive electrode side electrode 22 to the negative electrode side electrode 23 with a larger area increases. As a result, the voltage on the positive electrode side of the voltage of the human body 70 is suppressed, and the negative electrode side becomes a high potential.

[0090] In addition, the thickness T1 of the human body side insulating material 46 is preferably 2.5 mm or less. Thereby, suitable numerical values can be obtained for the human body capacitances C1 and C2 (see FIG. 1) that are capacitive couplings with the human body 70. Further, the thickness T2 of the opposite side insulating material 47 is 10 mm to 25 mm.

[0091] FIG. 9(A) is a perspective view showing a state in which the auxiliary insulating sheet 48 of the high-voltage conductor 3 having the auxiliary insulating sheet 48 is expanded, and FIG. 9(B) is a perspective view showing a state in which the auxiliary insulating sheet 48 is folded. Referring to FIG. 9(A), the high-voltage conductor 3 may be provided with an auxiliary insulating sheet 48.

[0092] The auxiliary insulating sheet 48 is a flexible sheet-like member formed of a synthetic resin material, and is provided on the side edge portion or the like of the high-voltage conductor 3 and extends outward from the side edge portion or the like of the high-voltage conductor 3. That is, the auxiliary insulating sheet 48 is provided in the vicinity of the side edge portion of the human body side insulating material 46 or the opposite side insulating material 47 that covers the positive electrode side electrode 22 (see FIG. 8(B)) and the negative electrode side electrode 23 (see FIG. 8(B)), and the auxiliary insulating sheet 48 itself does not directly cover the positive electrode side electrode 22 and the negative electrode side electrode 23.

[0093] As shown in FIG. 9(B), the auxiliary insulating sheet 48 is foldable and can be overlapped with the human body side insulating material 46 and the opposite side insulating material 47.

[0094] By providing such an auxiliary insulating sheet 48, for example, when using a high-voltage conductor 3 with a narrow width and a human body 70 (see FIG. 1) protrudes, the auxiliary insulating sheet 48 can be unfolded and used, and the part of the human body 70 protruding from the high-voltage conductor 3 can be placed on the upper surface of the auxiliary insulating sheet 48. Also, for example, normally, as shown in FIG. 9(B), the high-voltage conductor 3 can be used with the auxiliary insulating sheet 48 folded.

[0095] FIG. 10 is a circuit diagram showing a schematic configuration of an electrotherapeutic apparatus 1 according to another embodiment of the present invention. Referring to FIG. 10, the electrotherapeutic apparatus 1 may include a grounding conductor 4 for applying a ground potential to the human body 70.

[0096] The grounding conductor 4 has a positive-side grounding electrode 55 and a negative-side grounding electrode 56. The positive-side grounding electrode 55 is an electrode through which a grounding current flows when the positive side of the output potential is applied to the high-voltage conductor 3, and the negative-side grounding electrode 56 is an electrode through which a grounding current flows when the negative side of the output potential is applied to the high-voltage conductor 3. The forms of the positive-side grounding electrode 55 and the negative-side grounding electrode 56 are the same as those of the positive-side electrode 22 and the negative-side electrode 23 of the high-voltage conductor 3 already described, and various forms can act.

[0097] The positive-side grounding electrode 55 and the negative-side grounding electrode 56 of the grounding conductor 4 are connected to a grounding circuit having a shunt resistance 63 via a grounding wiring 52 and a grounding terminal 49. Specifically, the positive-side grounding electrode 55 is connected to the grounding circuit of the main body unit 2 via a positive-side grounding wiring 53 and a positive-side grounding terminal 50, and the negative-side grounding electrode 56 is connected to the grounding circuit of the main body unit 2 via a negative-side grounding wiring 54 and a negative-side grounding terminal 51.

[0098] A grounding conductor rectifying circuit 57 that divides the grounding circuit according to the flowing direction of the grounding current is provided in the grounding circuit to which the grounding conductor 4 is connected.

[0099] The ground conductor rectifying circuit 57 is provided with a positive electrode side ground electrode rectifying circuit 58 that is connected to the positive electrode side ground electrode 55 and reverses the direction of the current flowing toward the positive electrode side ground electrode 55. The positive electrode side ground electrode rectifying circuit 58 is, for example, a diode.

[0100] Also, the ground conductor rectifying circuit 57 is provided with a negative electrode side ground electrode rectifying circuit 59 that is connected to the negative electrode side ground electrode 56 and makes the direction of the current flowing toward the negative electrode side ground electrode 56 the positive direction. The negative electrode side ground electrode rectifying circuit 59 is, for example, a diode.

[0101] With such a configuration, it is possible to efficiently and effectively treat a plurality of treatment target sites on the human body 70 to which the positive electrode side ground electrode 55 and the negative electrode side ground electrode 56 are attached without changing the mounting position of the high voltage conductor 3.

[0102] Specifically, when a positive electrode side output potential is applied to the high voltage conductor 3, a suitable treatment current can flow through a path that connects from the high voltage conductor 3 through the human body capacitance C3, the human body 70, and the human body capacitance C4 to the positive electrode side ground electrode 55.

[0103] Also, when a negative electrode side output potential is applied to the high voltage conductor 3, a suitable treatment current can flow through a path that connects from the negative electrode side ground electrode 56 through the human body capacitance C5, the human body 70, and the human body capacitance C3 to the high voltage conductor 3.

[0104] Note that the ground conductor rectifying circuit 57 may be provided with a switch 60 connected in parallel with the positive electrode side ground electrode rectifying circuit 58 and a switch 61 connected in parallel with the negative electrode side ground electrode rectifying circuit 59. The switch 60 is a short-circuit switch that can short-circuit the positive electrode side ground electrode rectifying circuit 58, and the switch 61 is a short-circuit switch that can short-circuit the negative electrode side ground electrode rectifying circuit 59.

[0105] Thereby, a control device (not shown) performs control to open and close the switch 60 or the switch 61, and can selectively short-circuit at least one of the positive electrode side ground electrode rectifying circuit 58 and the negative electrode side ground electrode rectifying circuit 59.

[0106] That is, by the ON / OFF control of the switch 60, the positive electrode side ground electrode 55 can also perform treatment in a state directly grounded like a normal grounded conductor. Also, by the ON / OFF control of the switch 61, the negative electrode side ground electrode 56 can also perform treatment in a state directly grounded like a normal grounded conductor.

[0107] Further, the ground conductor rectifying circuit 57 side of the positive electrode side ground electrode rectifying circuit 58 and the ground conductor rectifying circuit 57 side of the negative electrode side ground electrode rectifying circuit 59 may be connected via a discharge resistor 62. The discharge resistor 62 may be, in addition to a resistor, a capacitor (not shown), a CR circuit, etc.

[0108] FIG. 11 is a circuit diagram showing a schematic configuration of the electrotherapy device 1 according to another embodiment of the present invention. Referring to FIG. 11, the ground conductor rectifying circuit 57 may be provided on the ground conductor 4 side outside the main body unit 2.

[0109] Specifically, the positive electrode side ground electrode rectifying circuit 58 and the negative electrode side ground electrode rectifying circuit 59 of the ground conductor rectifying circuit 57 may be provided inside the ground conductor 4. With such a configuration, the connection from the main body unit 2 to the positive electrode side ground electrode rectifying circuit 58 and the negative electrode side ground electrode rectifying circuit 59 can be combined into one ground wiring 52.

[0110] Thereby, the user can easily connect the plurality of provided positive electrode side ground electrode rectifying circuits 58 and negative electrode side ground electrode rectifying circuits 59 by simply connecting one ground wiring 52 to one ground terminal 49 provided in the main body unit 2, and can also easily remove it.

[0111] FIG. 12 is a diagram showing the ground conductor 4 according to another embodiment of the present invention. Referring to FIG. 12, the positive electrode side ground electrode 55 and the negative electrode side ground electrode 56 may be integrally provided with respect to a common ground conductor 4.

[0112] The positive electrode side ground electrode 55 and the negative electrode side ground electrode 56 are provided separately so as to secure a space for mounting the high voltage conductor 3 between the positive electrode side ground electrode 55 and the negative electrode side ground electrode 56. Thereby, the high voltage conductor 3 can be arranged, for example, at substantially the center of the ground conductor 4, which is between the positive electrode side ground electrode 55 and the negative electrode side ground electrode 56. And a suitable treatment current can be passed through a desired treatment target site in a wide range of the human body 70 (see FIG. 1).

[0113] FIG. 13 is a diagram showing the conductor unit 5 of the electrotherapy device 1 according to another embodiment of the present invention. Referring to FIG. 13, the high voltage conductor 3 and the ground conductor 4 may be integrated to form one conductor unit 5.

[0114] Specifically, the conductor unit 5 is provided with at least one high voltage conductor 3 and at least one ground conductor 4. And at least one of the high voltage conductor 3 and the ground conductor 4 is divided into a positive electrode side electrode and a negative electrode side electrode. That is, for example, the high voltage conductor 3 may have a positive electrode side electrode 22 and a negative electrode side electrode 23. Also, for example, the ground conductor 4 may have a positive electrode side ground electrode 55 and a negative electrode side ground electrode 56.

[0115] Also, the positive electrode side diode 14 and the negative electrode side diode 15 of the rectifier output circuit 13 connected to the positive electrode side electrode 22 and the negative electrode side electrode 23 of the high voltage conductor 3 may be provided inside the conductor unit 5. Thereby, by connecting a single output wiring 19 to the output terminal 16 of the main body unit 2 (see FIG. 11), a plurality of positive electrode side electrodes 22 and negative electrode side electrodes 23 can be connected to the main body unit 2.

[0116] Also, the positive electrode side ground electrode rectifier circuit 58 and the negative electrode side ground electrode rectifier circuit 59 of the ground conductor rectifier circuit 57 connected to the positive electrode side ground electrode 55 and the negative electrode side ground electrode 56 of the ground conductor 4 may be provided inside the conductor unit 5. Thereby, by connecting a single ground wiring 52 to the ground terminal 49 of the main body unit 2, a plurality of positive electrode side ground electrodes 55 and negative electrode side ground electrodes 56 can be connected to the main body unit 2.

[0117] Regarding the respective shapes, quantities, arrangements, etc. of the positive electrode 22 and the negative electrode 23 as the high-voltage conductors 3 and the positive electrode ground electrode 55 and the negative electrode ground electrode 56 as the ground conductors 4, various modified embodiments can be adopted.

[0118] According to the conductor unit 5 in which the high-voltage conductor 3 and the ground conductor 4 are integrated in this way, a plurality of treatment target sites can be suitably treated without changing the wearing position on the human body 70 (see FIG. 10). In addition, the user can easily perform wearing, removal, storage, tidying, etc. of the high-voltage conductor 3 and the ground conductor 4 on the human body 70.

[0119] Note that the present invention is not limited to the above-described embodiment. Other various modifications can be made without departing from the gist of the present invention.
