Description

[Technical field]

[0001] The present invention relates to an electric potential therapy device that performs treatment by utilizing an electric field, and in particular to an electric potential therapy device that is capable of adjusting the treatment sensation (the sensation that the person being treated feels that he or she is receiving electric potential therapy) without changing the electric field strength. [Background technology]

[0002] An electric potential therapy device for treating headaches, stiff shoulders, etc. is known as a device that uses a high-voltage transformer to boost the voltage of a commercial power source and generate a high voltage (see, for example, Patent Document 1). This electric potential therapy device applies the high voltage generated by the high-voltage transformer to electrodes, and applies the high voltage to an affected area or the entire body of the human body that is insulated from the earth to perform treatment.

[0003] FIG. 3 is a perspective view showing an example of the configuration of an electric potential therapy device 100, which is shown as a conventional example of such an electric potential therapy device. FIG. 4 is a functional block diagram showing an example of the functional configuration of the electric potential therapy device 100 of FIG. 3. This electric potential therapy device 100 includes, as its external appearance, a chair 101 on which the person to be treated H sits, a handheld operation unit 102 arranged on the armrest of the chair 101 to operate the electric potential therapy device 100, current supply units 103 and 104, and a footrest 105, and includes, as its internal functional configuration, a power plug 106, a main switch 107, an output switch 108, an AC / DC converter 109, a high-voltage transformer 110, a microcomputer 111, an operation unit 112, electrodes 113 and 114, and a heater 115. The operation unit 112 of FIG. 4 is provided on the handheld operation unit 102 arranged on the armrest in the actual electric potential therapy device 100 as shown in FIG. 3.

[0004] The current-carrying units 103, 104 are configured by covering the electrodes 113, 114 with an insulator, respectively, in order to apply a high voltage to generate an electric field around the person H. The current-carrying unit 103 is disposed on the upper part of the backrest of the chair 101 so as to be located above the head of the person H when he / she is seated in the chair 101. The current-carrying unit 104 is disposed within the seat of the chair 101 on which the person H is seated.

[0005] The footrest 105 has a built-in heater 115 and functions as a warmer, as well as an earth electrode.

[0006] As shown in Fig. 4, when the electric potential therapy device 100 is driven while the person to be treated H is seated, high voltages are applied to the electrodes 113 and 114, respectively, and an electric field is generated between the current-carrying units 103 and 104, thereby performing treatment. Note that high voltages of opposite phases are applied to the current-carrying units 103 and 104.

[0007] High voltage transformer 110 is housed in a case (not shown) provided at the bottom of the back of chair 101 of electric potential therapy apparatus 100, and a power cord extends from this case, with a power plug 106 at its end. A main switch 107 is also provided in the case, and when main switch 107 is turned on, power is supplied to electric potential therapy apparatus 100, and electric potential therapy apparatus 100 goes into standby mode.

[0008] The output switch 108 is disposed between the main switch 107 and the high-voltage transformer 110, and is controlled by a microcomputer 111. The microcomputer 111 is controlled by the operation of an operation unit 112, which is disposed in the handheld operation unit 102 in FIG.

[0009] Display means such as LEDs and LCDs and switches (both not shown) are arranged on the hand-held operation unit 102, and when the switches are operated, they control the microcomputer 111 to perform on / off control of the output switch 108 and turn on / off the LEDs, LCDs, etc. The AC / DC converter 109 is arranged between the main switch 107 and the microcomputer 111, and when the main switch 107 is turned on, it converts alternating current (AC) from the power plug 106 into direct current (DC) and supplies power to the microcomputer 111. A high voltage generated by a high-voltage transformer 110 is applied to the electrodes 113 and 114.

[0010] When power is supplied from power plug 106 and main switch 107 is turned on, electric potential therapy device 100 waits for operation of operation unit 112 (standby state). Next, when output switch 108 is turned on by operating operation unit 112 to control microcomputer 111, high voltage is generated by high voltage transformer 110, and high voltage is applied to electrodes 113 and 114, generating an electric field between current-carrying unit 103 and current-carrying unit 104. Note that high voltage transformer 110 is shown as one block because it is configured as a so-called twin transformer having two output ports in opposite phases for one input. Of course, separate high voltage transformers may be used for electrodes 113 and 114.

[0011] When an electric field is generated between the current-carrying portion 103 and the current-carrying portion 104, the LED, LCD, etc. are caused to emit light in the handheld operation portion 102 at the same time under the control of the microcomputer 111.

[0012] Patent Document 1 shows an electric potential therapy device similar to the electric potential therapy device 100 described above, in which a display / input control circuit 14 controls the output of a high-voltage transformer T1 and the display / non-display of a display means. [Prior art documents] [Patent documents]

[0013] [Patent Document 1] JP 2017-038836 A Summary of the Invention [Problem to be solved by the invention]

[0014] From the viewpoint of safety, the value of the therapeutic current output from the lead portion of the electric potential therapy device 100 is regulated by the JIS standard.

[0015] Therefore, a protective resistor (not shown) for preventing electric shock is provided on the output side of high-voltage transformer 110 of electric potential therapy device 100 so that the output therapy current from current-carrying parts (conductor parts) 103, 104 is "below the JIS specified value."

[0016] The therapeutic sensation is one of the bodily sensations experienced during treatment with the electric potential therapeutic device 100, and can also be felt by the treated person H during normal treatment; however, when the treated person H brings part of his / her body close to a surrounding wall (ground), etc., a slight discharge occurs between the wall and part of the body, causing the treated person H to experience a stronger "tingling" sensation.

[0017] This is because, when treatment is being performed with the electric potential treatment device 100, the human body electric potential of the person being treated H becomes high, causing an electric potential difference between the person being treated H and the surrounding walls, etc.

[0018] Furthermore, the body potential of the person to be treated H is directly proportional to the voltage of the high voltage transformer 110; if the voltage is high, the body potential is high, and conversely, if the voltage is low, the body potential is low.

[0019] The sensation of this treatment varies from person to person, and also varies depending on the environment in which the electric potential treatment device 100 is placed, such as humidity and temperature.

[0020] Also, if you perform electrical potential treatment for many years, you may become accustomed to it and may not feel the treatment as much.

[0021] On the other hand, the electric field generated by the electric potential therapy device 100 is invisible, and depending on the person being treated H, in order to recognize that they are receiving treatment due to the above-mentioned "treatment sensation," they may go out of their way to place part of their body close to a wall or the like.

[0022] Then, when the person H begins to feel that the sensation of the treatment has weakened (due to the environment, getting used to it, etc.), he / she may mistakenly believe that the electric potential treatment device 100 has broken down.

[0023] Therefore, an object of the present invention is to provide an electric potential therapeutic device that enables the subject H to adjust the sensation of the therapeutic treatment he or she receives at his or her will. [Means for solving the problem]

[0024] In order to solve the above problem, the present invention relates to a high-voltage transformer that boosts an input voltage to generate a high voltage, and a Multiple An electrode; The plurality of electrodes The high voltage generated by the high voltage transformer By applying An electric potential treatment device for treating a patient, comprising: Multiple electrode for , voltages in phase and selectively applying a voltage to at least one of the plurality of electrodes via a changeover switch, and adjusting the body potential of the subject by changing the area of ​​the electrode to which the voltage is applied by changing the changeover switch. It is characterized by: Effect of the Invention

[0026] According to the invention described in claim 1, Multiple electrode To , voltages in phase and selectively applying a voltage to at least one of the plurality of electrodes via a changeover switch, and adjusting the body potential of the subject by changing the area of ​​the electrode to which the voltage is applied by changing the changeover switch. This allows the person being treated to increase or decrease the body potential.

[0027] In other words, without changing the electric field strength, by increasing the contact area between the human body and the electrodes, the human body potential can be increased and the therapeutic sensation can be strengthened, and by decreasing the contact area between the human body and the electrodes, the human body potential can be decreased and the therapeutic sensation can be weakened.

[0028] In this way, the human body potential can be adjusted with a simple configuration of flipping a switch, the sensation of treatment can be adjusted and set to suit the preferences of the person being treated, and by changing the settings when the sensation of treatment becomes weak, it is possible to prevent this from being mistaken for a malfunction of the potential treatment device. [Brief description of the drawings]

[0030] [Figure 1] 1 is a functional block diagram showing the functional configuration of an electric potential therapeutic device 1 according to a first embodiment of the present invention. [Diagram 2] 5 is a functional block diagram showing the functional configuration of an electric potential therapeutic device 30 according to a second embodiment of the present invention. FIG. [Diagram 3] FIG. 1 is a perspective view showing an example of the configuration of a conventional electric potential therapeutic device. [Figure 4]4 is a functional block diagram showing an example of the functional configuration of the electric potential therapy device of FIG. 3. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] The present invention will now be described with reference to the accompanying drawings.

[0032] (Embodiment 1) Fig. 1 shows an electric potential therapy device 1 according to this embodiment 1, and is a functional block diagram showing a functional configuration. This electric potential therapy device 1 is a device that applies a high voltage generated by a high voltage transformer to electrodes, and applies the high voltage to an affected part or the whole body of a human body insulated from the earth to perform treatment, and like the electric potential therapy device 100 in Fig. 3, has an external appearance of a chair 11 on which the person to be treated H sits, a handheld operation unit (shown as operation unit 23 in Fig. 1, separated from chair 11) disposed on the armrest of chair 11 to operate electric potential therapy device 1, three current-carrying units 12, 13, 14, and a footrest 15.

[0033] Of the electric current-carrying units 12, 13, and 14, one is a head electric current-carrying unit 12 arranged so as to be positioned above the head of the person being treated H, one is a seat electric current-carrying unit 13 arranged in the seat of the chair 11, and the other is a back electric current-carrying unit 14 arranged in the backrest of the chair 11.

[0034] Similarly to the electric potential therapy device 100 of FIG. 4, the electric potential therapy device 1 has, as its internal functional configuration, a power plug 16, a main switch 17, an output switch 18, a high-voltage transformer 19, an AC / DC converter 21, a microcomputer 22, an operating unit 23, electrodes 24, 25, and a heater 27, and the functions of each component are substantially the same as those of the electric potential therapy device 100 described above, but differs in the points described below.

[0035] That is, the electric potential therapy device 1 of this embodiment 1 differs from the conventional electric potential therapy device 100 illustrated in FIG. 4 in that there is a changeover switch (20) in addition to the output switch (18), that there are two electrodes other than the head electrode, a seat electrode 25 and a back electrode 26, and that the number of high-voltage transformers has been increased accordingly to accommodate the increased number of electrodes.

[0036] One high-voltage transformer 19A is connected between the output switch 18 and the head electrode 24, and the other high-voltage transformer 19B is connected between the output switch 18 and the seat electrode 25 and back electrode 26. In addition, a changeover switch 20 is provided between the other high-voltage transformer 19B and the back electrode 26.

[0037] When the output switch 18 is turned on, a high voltage is generated by the high voltage transformer 19A and the high voltage transformer 19B, and the high voltage is applied to the head electrode 24 and the seat electrode 25, respectively, generating an electric field between the current-carrying unit 12 and the current-carrying unit 13. The patient H, seated on the chair 11, is in close contact with the seat electrode 25, which increases the human body potential and gives a sense of treatment. At this time, the changeover switch 20 is still in the off state. Here, "close contact" means that the seat electrode 25 is covered and built into the current-carrying unit 13 as an insulator, so that the degree of contact is increased by making the thickness of the insulator thinner, thereby increasing the human body potential. Note that high voltages of opposite phases are applied to the head electrode 24 and the seat electrode 25, and thus the head electrode 24 is used as a counter electrode facing the seat electrode 25, thereby forming a stable electric field.

[0038] Next, when the changeover switch 20 arranged between the other high-voltage transformer 19B and the back electrode 26 is turned on, a high voltage of the same phase as that of the seat electrode 25 is also applied to the back electrode 26, and the subject H comes into contact with the two seat electrodes 25 and the back electrode 26 to which the high voltage has been applied, thereby further increasing the human body potential of the subject H, and allowing him or her to feel a stronger sensation of treatment.

[0039] This is because the human body potential is higher when a high voltage is applied only to the seat electrode 25 than when a high voltage is selectively applied to the seat electrode 25 and the back electrode 26. Moreover, the applied electric field strength is not changed whether a high voltage is applied only to the seat electrode 25 or simultaneously to the seat electrode 25 and the back electrode 26.

[0040] In the electric potential therapy device 1 according to this embodiment 1, after the output switch 18 is turned on, the changeover switch 20 is selectively turned on, that is, by switching the changeover switch 20 based on the will of the person being treated H, the human body electric potential can be easily adjusted without changing the electric field strength, thereby realizing a preferred therapeutic sensation. Furthermore, when the therapeutic sensation becomes weaker, by changing the settings, it is possible to determine whether or not there is a malfunction in the electric potential therapy device 1, thereby preventing it from being mistaken for a malfunction.

[0041] Although the high-voltage transformer 19B has been described as having two in-phase output ports, the present invention is not limited to this, and it may be configured with separate high-voltage transformers as shown in the following second embodiment.

[0042] (Embodiment 2) 2 is a functional block diagram showing a functional configuration of an electric potential therapy device 30 according to this embodiment 2. The main points of difference between the electric potential therapy device 30 and the electric potential therapy device 1 according to the above-mentioned embodiment 1 are that two electrodes to which high electric potentials of the same phase are applied are arranged in the seat part, that three high-voltage transformers are provided to apply high voltages separately to the two electrodes in the seat part and the head electrode, and that a high-voltage transformer is arranged between the main switch 17 and the high-voltage transformers. Switch The difference is in the number and positions of the .pi.s. The other configurations are almost the same, so the same reference numerals are used and the description will be omitted.

[0043] Like the electric potential therapy device 1 of embodiment 1 above, the electric potential therapy device 30 has, as its internal functional configuration, a power plug 16, a main switch 17, an AC / DC converter 21, a microcomputer 22, an operating unit 23, and a heater 27, and the functions of each of these components are approximately the same as those of the electric potential therapy device 1 above.

[0044] As in embodiment 1, the electric potential therapy device 30 has electric current sections 12, 13, one of which is a head electric current section 12 arranged so as to be positioned above the head of the person to be treated H, and the other is a seat electric current section 13 arranged in the seat of the chair 11, with a head electrode 24 being arranged on the head electric current section 12 and two seat electrodes 31, 32 being arranged in a front-to-back position on the seat electric current section 13.

[0045] These electrodes 24, 31, 32 are connected to separate high voltage transformers 33A, 33B, 33C, respectively.

[0046] The output switch 34A is connected to the rear of the main switch 17. Changeover switch The high-voltage transformer 33A and the high-voltage transformer 33B are connected to the output switch 34A. Changeover switch The high voltage transformer 33C is connected to the rear stage of 34B.

[0047] and, Output Switch When 34A is turned on, high voltage is generated by the high voltage transformer 33A and the high voltage transformer 33B, and this high voltage is applied to the head electrode 24 and one of the electrodes 31 of the seat. As a result, an electric field is generated between the current-carrying unit 12 and the current-carrying unit 13, and the person H seated on the chair 11 is in contact with the seat electrode 31, so that the human body potential is increased and the person H feels a sense of treatment. Note that high voltages of opposite phases are applied to the head electrode 24 and the seat electrode 31, and thus the head electrode 24 is made to be a counter electrode facing the seat electrode 31, so that a stable electric field can be formed. Note that the high voltage transformers 33A and 33B may be so-called twin transformers, similar to the high voltage transformer 110 in the above-mentioned conventional electric potential treatment device 100.

[0048] Also, Changeover switch When 34B is turned on, a high voltage is generated by the high voltage transformer 33C, and the high voltage is applied to the other electrode 32 of the seat. In combination with the output switch 34A being turned on, the human body potential of the person H is further increased, so that the person H feels a stronger sense of treatment. The two seat electrodes 31 and 32 are applied with high voltages of the same phase.

[0049] This is because the human body potential is higher when a high voltage is selectively applied only to the seat electrode 31 than when a high voltage is simultaneously applied to the two seat electrodes 31 and 32. Moreover, the applied electric field strength is not changed whether a high voltage is selectively applied only to the seat electrode 31 or when a high voltage is simultaneously applied to the two seat electrodes 31 and 32.

[0050] In the above-mentioned second embodiment, the two seat electrodes 31, 32 are arranged in front and behind, but the present invention is not limited to this, and the two seat electrodes may be arranged side by side on the left and right.

[0051] Thus, even in the electric potential therapeutic device 30 according to the second embodiment, Changeover switch 34B is selectively turned on, i.e., based on the will of the person being treated H. Changeover switch By switching 34B, the human body potential can be easily adjusted without changing the electric field strength, thereby enabling a preferred therapeutic sensation to be achieved. Furthermore, when the therapeutic sensation is felt to have weakened, it is possible to determine whether or not there is a malfunction of the electric potential therapeutic device 30 by changing the settings, thereby preventing it from being mistaken for a malfunction.

[0052] In the above first and second embodiments, the case where the number of electrodes to which the high voltage of the same phase is applied is two has been described, but the present invention is not limited to this, and the number of electrodes may be three or four.

[0053] The positions of the multiple electrodes to which the high voltage of the same phase is applied may be two on the seat, or one on the seat and one on the back, as in the above-mentioned first and second embodiments. Also, without being limited to these, two may be provided on the back. Furthermore, electrodes may be provided on the feet (thighs, calves, etc.). In short, as long as multiple electrodes are arranged and high potentials of the same phase are applied to each electrode selectively or simultaneously, thereby making it possible to adjust the human body potential, the present invention is not limited to the above-mentioned embodiments.

[0054] The application of a potential to each electrode may be performed by a high-voltage transformer provided separately for each electrode, or by a high-voltage transformer having one input and two or more output ports.

[0055] The voltages applied to the electrodes 25, 26 or 31, 32 that come into contact with the human body may be the same or different.

[0056] In the above embodiments 1 and 2, an electric potential therapy device is described that forms an electric field between the head electrode and the seat electrode or the back electrode, but the present invention is not limited to this and may also be an electric potential therapy device that applies a high potential only to the seat electrode (in this electric potential therapy device, an electric field is formed between the seat electrode and an earth such as a ceiling or wall).
