 Problems to be solved by the invention

[0004] By the way, near ground (earth) potential such as walls and electrical equipment! ヽ If an object is located in the vicinity (surrounding) of a human body undergoing potential treatment, an appropriate therapeutic effect cannot be obtained. Will occur. In other words, the electric field strength is high near the wall and the electric field formed around the human body. The field strength changes depending on the part of the human body), and the prescribed (appropriate) therapeutic effect may not be obtained (see Fig. 5 (c)). In addition, the remote controller and drive mechanism are operated and driven at a low voltage (for example, 12V), so that they are close to the ground potential.In this case, the electric field is similarly affected, and the remote controller and drive mechanism are placed near the human body. It was not preferable from the viewpoint of treatment to dispose it.

 [0005] On the other hand, such potential treatment devices described in Patent Documents 1 and 2 control electric field strength or increase electric field strength around the human body, but in the vicinity of the human body.

In other words, the electric field located between the protective electrode and the wall is greatly affected by the wall, etc.), but the electric field located between the protective electrode and the human body, that is, around the human body is formed. The electric field is not protected by the protective electrode), so the influence of the wall is suppressed. As a result, even if walls and electrical equipment are located in the vicinity of the human body, the influence on the electric field formed around the human body is suppressed. It is possible to exert and maintain a proper and stable predetermined therapeutic effect.

 [0010] In addition, by disposing the protective electrode on the back side of the human body, it becomes possible to provide a drive mechanism for driving the main electrode located above the head of the human body on the back side of the backrest.

 BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, the present invention will be described based on the illustrated embodiments.

 FIG. 1 is a front perspective view (configuration diagram) of an electric potential therapy apparatus 1 according to an embodiment of the present invention, and FIG. 2 is a rear perspective view thereof. This potential therapy device 1 mainly includes a potential therapy device 2 and a high voltage generator 3.

[0015] The electric potential therapy device 2 includes a chair 21, a head cover 22, and a footrest 23 on which the subject C sits. The chair 21 is covered with an insulator, and a seat main electrode 4 (main electrode) is embedded in the seat 21a. Further, the head cover 22 and the footrest 23 are also covered with an insulating material, the head main electrode 5 (main electrode) is embedded in the head cover 22, and the ground electrode 6 (main electrode) is embedded in the footrest 23. The seat main electrode 4 and the head main electrode 5 Connected to the voltage output terminal of the device 3, the ground electrode 6 is connected to the ground terminal of the high voltage generator 3.

 Reference numeral 24 denotes a drive arm (drive mechanism) for driving the head cover 22, and this drive arm 24 is disposed on the upper back side of the backrest 21 b of the chair 21. That is, a headrest 21c formed so as to cover the shoulder force head of the subject C is provided above the backrest 21b, and a drive arm 24 is provided so as to protrude upward from the back side of the headrest 21c. ing. In addition, a side wall 21d is provided on both sides (left and right) of the seat 21a to cover the lower body side of the patient C, and a remote control 25 (remote control) is provided outside one side wall 21d (on the opposite side of the seat 21a). Controller). Insulating legs (not shown) for insulating the floor force are attached to the lower surface of the side wall 21d or the seat 21a.

 [0017] As shown in FIG. 3, a first protective electrode 7 and a second protective electrode 8 are embedded in the headrest 21c and the sidewall 21d, respectively. The first protective electrode 7 and the second protective electrode 8 are used by a patient C of standard body type who sits on the chair 21 in a standard posture and applies a high voltage to the seat main electrode 4 and the head main electrode 5. Is applied along a predetermined equipotential surface of the electric field formed around the subject C. Further, the potential force of the first protective electrode 7 and the second protective electrode 8 is set to be the same potential as the potential on the equipotential surface. Specifically, the first protective electrode 7 and the second protective electrode 8 are highly flexible conductive sheets in which a mesh-like copper wire is woven into the grease, and the first protective electrode 7 is the patient C. The shoulder force is formed (arranged) along the equipotential surface of the electric field formed around the back surface of the head. Further, the second protective electrode 8 is formed (arranged) along the equipotential surface of the electric field formed around the lower body side of the subject C (the hip force is also applied to the knee 4), and the chair 21 In the state where the patient C is sitting, the side of the patient C is placed so as to cover the side facing the knee. The first protective electrode 7 and the second protective electrode 8 are connected to the voltage output terminal of the high voltage generator 3 so that a voltage having the same potential as the potential on each equipotential surface is applied.

[0018] A high voltage generator 3 shown in Fig. 4 described later includes a power cord for commercial power supply (not shown), a boost transformer 31 (high voltage transformer) for boosting the voltage to 7,000 to 9, OOOV. And a voltage output terminal for outputting a voltage. Then, it is generated by the step-up transformer 31. The generated voltage (high voltage) is applied to the seat main electrode 4, the head main electrode 5, the first protective electrode 7, and the second protective electrode 8 through the voltage output terminal.

FIG. 4 shows a schematic equivalent circuit of the potential treatment device 1 having such a configuration. In the figure, symbol V is a commercial power source, symbol 3 is a high voltage generator, and symbols Z1 to Z4 are safety resistors that increase the output impedance to prevent electric shock due to electrodes 4, 5, 7, and 8. The voltage from the step-up transformer 31 is output to the head main electrode 5 via the first safety resistor Z1, and is output to the first protective electrode 7 via the second safety resistor Z2, and the third safety resistor Z3. Is output to the second protective electrode 8 and is output to the seat main electrode 4 via the fourth safety resistor Z4. Furthermore, in order to suppress the potential of the first protective electrode 7 and the second protective electrode 8 from being affected by the wall or the like, that is, the potential of the first protective electrode 7 and the second protective electrode 8 is induced to a high potential. In order to be dependent on the potential of the patient C, the impedance of the second safety resistor Z2 and the third safety resistor Z3 is set lower than the first safety resistor Z1 and the fourth safety resistor Z4. Yes. The remote controller 25 is used to remotely operate the high voltage generator 3 such as operation and stop.

 Next, the operation and effect of the potential treatment device 1 having such a configuration will be described.

First, the patient C is seated on the chair 21 and the high voltage generator 3 is operated. As a result, a high voltage is applied to the seat main electrode 4 and the head main electrode 5, the patient C is brought to a high potential, and an electric field is formed around the patient C. An equipotential surface of this electric field is formed around the subject C. For example, as shown in Fig. 5 (a), in the upper part of the person to be treated who is in contact with the headrest 21c (the part from the shoulder to the head), the person C is at the center and the annual rings around it. The upper equipotential surfaces Pl to Pn are formed. In other words, if the patient C is induced at 1, OOOV, the patient C force is also directed outward, and is called the 900V equipotential surface Pl, the 800V equipotential surface P2, and the 700V equipotential surface P3. Thus, equipotential surfaces with lower potentials are formed sequentially. In addition, the equipotential planes Pl to Pn have a greater distance between equipotential planes and a lower electric field strength as the potential of the equipotential plane is lower (as the force is directed outward from the patient C).

[0022] Incidentally, as described above, the first protective electrode 7 and the second protective electrode 8 are disposed along a predetermined equipotential surface of the electric field formed around the subject C, and First protective electrode 7, second The potential of the protective electrode 8 is set to be the same as that on the equipotential surface. For example, as shown in FIG. 5 (a), the first protective electrode 7 is disposed in the headrest 21c along the equipotential plane P2, and the high voltage generator 3 To The voltage is applied. That is, the equipotential surface P2 and the first protective electrode 7 are in a state of overlapping (matching) with the shape (surface) and the potential!

 [0023] In this state, for example, when the ground potential is close! And the wall W is positioned in the vicinity of the patient C (in this case, the headrest 21c), the equipotential planes Pl to Pn are caused by the wall W. Changed (disturbed). That is, as shown in FIG. 5 (b), the equipotential surfaces P3 to Pn located between the wall W having the potential of approximately OV and the first protective electrode 7 are crushed, and the interval is narrowed. The electric field strength increases. On the other hand, the equipotential surfaces P1 to P2 positioned between the patient C and the first protective electrode 7 are not protected by the first protective electrode 7), and the electric field strength is not changed. That is, the first protective electrode 7 is formed (arranged) along the equipotential surface P2 and is set to the same potential as the equipotential surface P2. Therefore, the first protective electrode 7 protects the equipotential surfaces P1 to P2. As a result, even if the wall W is located in the vicinity, the equipotential surfaces P1 to P2 around the subject C and the electric field are not changed (influenced), and the wall W is not located in the vicinity! The predetermined therapeutic effect is appropriately and stably exhibited and maintained.

 On the other hand, if the first protective electrode 7 is provided, all the equipotential surfaces Pl to Pn are changed by the wall W as shown in FIG. That is, all equipotential surfaces P1 to Pn are crushed, the interval between them is narrowed, and the electric field strength is increased. As a result, the electric field strength formed around the subject C is changed depending on the part of the human body), and a predetermined (appropriate) therapeutic effect cannot be obtained.

[0025] As described above, according to the potential treatment apparatus 1, even when the wall W or the like is located in the vicinity, the electric field around the subject C is not changed, and an appropriate and stable treatment effect is obtained. It is done. That is, a predetermined therapeutic effect can be stably obtained regardless of whether or not there is a wall W around the periphery. Further, since the drive arm 24 is disposed on the back side of the headrest 21c, that is, outside the first protective electrode 7 (on the opposite side to the patient), even when the drive arm 24 is close to the ground potential. As in the case of wall W above, the electric field around the subject C changes. Therefore, an appropriate and stable therapeutic effect can be obtained. Similarly, since the remote controller 25 is disposed outside the side wall 21d, that is, outside the second protective electrode 8 (opposite to the patient C), the electric field around the patient C is controlled by the remote controller 25. No change is made, and an appropriate and stable therapeutic effect is obtained. Furthermore, since the first protective electrode 7 is disposed in the headrest 21c and the second protective electrode 8 is disposed in the side wall 21d, the headrest 21c is driven to the rear side without affecting the therapeutic effect. An arm 24 or the like can be arranged, or a remote control 25 or the like can be arranged outside the sidewall 21d. That is, the function (attached device) of the potential treatment device 1 can be added and the degree of freedom in design can be increased, and the framework of the chair 21 itself can be made of a metal material, which is advantageous in terms of strength.

By the way, in this embodiment, for example, the potential of the first protective electrode 7 is set to 800 V (equal potential) so that the potentials of the first protective electrode 7 and the second protective electrode 8 are the same as the potential on the equipotential surface. The same effect can be obtained even if the force applied with the voltage from the high-voltage generator 3 is not the same as the potential on the equipotential surface. That is, if the potentials of the first protective electrode 7 and the second protective electrode 8 are approximately the same as the potential on the equipotential surface, the distance between the patient C and the first protective electrode 7 and the second protective electrode 8 As a result, the equipotential surface located in the region does not change greatly, and a predetermined therapeutic effect is obtained. For example, in the case of the first protective electrode 7 described above, even if the potential is 700 V, the equipotential surfaces P1 to P2 are protected (not greatly changed), and a predetermined therapeutic effect is obtained. On the other hand, since the first protective electrode 7 and the second protective electrode 8 are arranged (formed) based on the standard posture of the standard patient C as described above, The equipotential surface of the electric field formed around C may not completely match. That is, even if the potentials of the first protective electrode 7 and the second protective electrode 8 are set to the same potential as that on the standard equipotential surface, the potentials do not match at least in part (the equipotential surface and In some cases, the first protective electrode 7 and the second protective electrode 8 do not match. However, even in such a case, there is an action (effect) for protecting the equipotential surface located between the patient C and the first protective electrode 7 and the second protective electrode 8, and the patient is treated. The electric field around the person C is not greatly changed, and a predetermined therapeutic effect is obtained. As described above, it is most preferable that the shape (arrangement state) of the first protective electrode 7 and the second protective electrode 8 and the potential thereof completely coincide with the shape of the equipotential surface and the potential. Same level An action (effect) is obtained. Therefore, the shapes of the first protective electrode 7 and the second protective electrode 8 and their potentials are determined according to the standard body of the patient C to be treated, the locations to be placed, the number to be placed, the degree of effect, etc. do it.

 In this embodiment, the potential treatment device 2 is the chair-type potential treatment device 1, but the potential treatment device is a bed-type potential treatment device. Of course, the protective electrode 8 may be provided.

It is extremely useful.
