As shown in FIGS. 1-3, the potential therapy apparatus 1 of this Embodiment 1 is equipped with the potential therapy apparatus 2 and the high voltage generator 3. As shown in FIG. The dislocation treatment device 2 has a chair 4 on which the subject A sits, and an energizer 5 on which the feet of the subject A are placed. The chair 4 is covered with an insulator, and in the seat portion 6, the left electrode 7 for embedding the current induced from the subject A is embedded in the state where the subject A is sitting. It is. The current collector 5 is covered with an insulator, and the lower electrode 8 is embedded therein.

Moreover, the operation part 9 containing the start switch 9a is arrange | positioned at the upper part of the side wall which covers the lower part of the torso side part of the to-be-treated person A. The left electrode 7 is connected to the detecting terminal 16d of the high voltage generator 3, the lower electrode 8 is connected to the voltage output terminal 16c, and the start switch 9a is connected to the connecting terminal 16e, 16f). In addition, in FIG. 3, the operation part 9 is shown by the part different from the chair 4 for convenience of description.

As shown in FIG. 3, the high voltage generator 3 includes a controller 11 that controls each component and serves as a safety device, a boost transformer 12 for boosting the voltage of the commercial power supply Sa, and a boost transformer ( A converter 13 for converting the tap on the primary side of 12), a safety resistor 14 for increasing the output impedance to prevent electric shock by the lower electrode 8, and an input connected to the commercial power supply Sa. Terminal 16a, 16b, voltage output terminal 16c to which lower electrode 8 is connected, detection terminal 16d to which left electrode 7 is connected, and connection terminal to which start switch 9a is connected. (16e, 16f).

The controller 11 has a main control part including a CPU and a current measuring part for measuring the induced current in the left electrode 7. The main controller performs induction current detection processing, high voltage application determination processing, and output interruption necessity determination processing. The main controller detects the induced current in the left electrode 7 based on the signal from the current measuring unit and performs the induced current detection process.

When the main control part becomes the pilot potential based on the detected induced current, the subject A stands on the energizing stand 5 and flows from the current Ip flowing in the state not seated on the chair 4 to the chair 4. It is determined that the current is changed to the current Iq (Ip << Iq) flowing in the state of sitting, and it is determined that the high voltage can be applied. Then, the high voltage application judgment processing is performed. A weak induction current flows to the left electrode 7.] And, when the induction current I exceeds a predetermined current value Ia (for example, Ia = Ip) (I> Ia), It is determined that high voltage can be applied. As a result, the main control unit controls the converter 13 to convert the pilot potential contact 13b into the therapeutic high potential contact 13c.

When the main control part becomes the therapeutic potential based on the detected induction current, from the current Ir flowing in the state in which the subject A is sitting in the chair 4 (Iq << Ir), from the chair 4 It is judged that the current Is (Is << Ir) which flows in the state where it is in the state where it is connected to the power supply board 5 is determined, and it is determined that an output interruption is necessary, and an output interruption determination process is performed. That is, the main controller determines that the output interruption is necessary when the induced current I becomes smaller than the predetermined current value Ib (for example, Ib = Ir) (I <Ib). Thereby, the main control part controls the conversion part 13, and converts into the OFF contact 13a from the therapeutic high potential contact 13c.

The converting section 13 is provided on the primary side of the boost transformer 12, the OFF contact 13a for cutting the input, and the pilot potential contact 13b for generating a low voltage without risk of electric shock on the secondary side. And a therapeutic high potential contact 13c for generating a therapeutic high voltage (for example, 7000 V? 9000 V) on the secondary side.

Next, with reference to FIG. 4, operation | movement of the potential therapy apparatus 1 of this embodiment is demonstrated. When the start switch 9a is turned on (step SA11 (FIG. 4)), the main controller of the controller 11 controls the converter 13 to switch from the OFF contact 13a to the pilot potential contact 13b. do. As a result, a pilot potential is applied to the lower electrode 8 (step SA12). In this state, the to-be-treated person A stands on the chair 4 after standing on the energizing stand 5.

Next, in step SA13, the main control section determines whether or not the induced current exceeds Ia, proceeds to step SA14 when the induced current exceeds Ia, and returns to step SA12 when the induced current is equal to or less than Ia. That is, the main controller determines that the high voltage can be applied by judging that the current Ip has changed from the current Ip to the current Iq (Ip << Iq) in the state where the pilot potential is reached based on the detected induced current.

In step SA14, the main control unit controls the conversion unit 13 to convert the pilot potential contact 13b into the therapeutic high potential contact 13c. As a result, a therapeutic potential is applied to the lower electrode 8.

Next, in step SA15, the main controller determines whether or not the current value of the induced current is smaller than Ib. This is to determine whether or not the subject C has risen to the state where the high potential is not to be applied after the therapeutic high potential is applied. If the current value of the induced current is smaller than Ib, the process proceeds to step SA16. If the current value is more than Ib, the process returns to step SA14. That is, the main control part is the current Is from the current Is flowing in the state where the subject A is sitting in the chair 4 in the state where it becomes the therapeutic potential on the basis of the detected induction current, Is Is << Ir ), It is determined that output interruption is necessary. In step SA16, the main control unit controls the conversion unit 13 to convert from the therapeutic high potential contact 13c to the OFF contact 13a. As a result, the output of the high voltage potential to the lower electrode 8 is cut off.

According to the configuration of this embodiment, first, the pilot potential without the risk of electric shock is applied to the lower electrode 8, the induced current in the left electrode 7 is measured, and the chair 4 of the subject A is treated. In the case of going up to the potential therapy device 2, it is determined whether or not a high voltage is applied in accordance with a change in the current value accompanying the seating of the furnace, and a therapeutic high voltage is applied to the energizing stand 5 when it is determined that the high voltage can be applied. Safety can be ensured without making the to-be-treated person A in an insulated state.

In addition, since the subject A determines whether or not output interruption is necessary in accordance with the change in the current value accompanying the fall from the chair 4, and the output is interrupted when it is determined that output interruption is necessary, the potential treatment device 2 In the case of descending from), safety can be ensured without causing the subject A to be insulated. Therefore, the insulator which has been used conventionally is not required, and the configuration can be simplified. Moreover, in the to-be-treated person A, since the insulation stand is not needed, the troublesomeness at the time of treatment is eliminated.

Further, since the subject A determines whether or not the output interruption is necessary in accordance with the change in the current value accompanying the fall from the chair 4, and when it is determined that the output interruption is necessary, the output of the high potential is blocked. Even when not being treated, i.e., without the subject C, no high voltage is applied, preventing waste of power and deterioration of the potential treatment device 1, thereby prolonging life. can do.

As shown in FIGS. 5-8, the potential treatment apparatus 17 of this Embodiment 2 is equipped with the potential treatment apparatus 18 and the high voltage generator 19. As shown in FIG. The dislocation treatment device 18 has a chair 20 on which the subject B sits, an energizing stand 21 on which the foot of the subject B is placed, and a head cover 22. The chair 20 is covered with an insulator, and the left electrode 24 is embedded in the seat 23. The current collector 21 and the head cover 22 are covered with an insulator, and the lower electrode 25 and the upper electrode 26 are embedded therein, and are treated by the potential difference between the lower electrode 25 and the upper electrode 26. Is performed.

Moreover, the operation part 27 containing a start switch is arrange | positioned at the upper part of the side wall which comprises the chair 20 and covers the lower part of the lower body side part of the to-be-treated person B. As shown in FIG. The left electrode 24 is connected to the detection terminal 35e of the high voltage generator 19, and the lower electrode 25 and the upper electrode 26 are connected to the voltage output terminals 35d and 35c, respectively. The start switch of the operation unit 27 is connected to the connection terminals 35f and 35g.

6 to 8, the high voltage generator 19 includes a controller 29 that controls each component and serves as a safety device, a boost transformer 31 that boosts the voltage of the commercial power supply Sb, The converter 32 for converting the tap on the primary side of the boost transformer 31 and the safety resistors 33b and 33a which increase the output impedance to prevent electric shock by the lower electrode 25 and the upper electrode 26, respectively. ), An input terminal connected to both ends of the secondary coil 3lb of the boost transformer 31, a connection converter 34 for converting the connection between the earth and safety resistor 33b, and a commercial power supply Sb. 35a and 35b, the detection terminal 35e to which the left electrode 24 is connected, the voltage output terminal 35d to which the lower electrode 25 is connected, and the voltage output terminal to which the upper electrode 26 is connected. 35c and connection terminal 35f, 35g to which the start switch of the operation part 27 is connected. In addition, in FIG.6 and FIG.7, the part shown with the code | symbol 19 is used for demonstrating "polarity."

The controller 29 has a main controller including a CPU and a current measuring unit 28 for measuring the induced current in the left electrode 24. The main controller executes induction current detection processing, high voltage application determination processing, polarity conversion control processing, and output interruption determination processing. The main controller detects the induced current in the left electrode 24 based on the signal from the current measuring unit, and performs the induced current detection process.

When the main control part becomes the pilot potential based on the detected induction current, the chair B stands out from the current Ip which flows in the state where the to-be-treated person B stands in the energizing zone 21 and does not sit on the chair 20. It is determined that the current Iq (Ip << Iq) flowing in the state of sitting is changed, and it is determined that the voltage can be applied, and the high voltage application determination process is performed. Then, the main controller determines that the high voltage can be applied when the induced current I exceeds the predetermined current value Ia (for example, Ia = Ip) (I> Ia). Thereby, the main control part controls the conversion part 32, and is converted from the pilot potential contact 32b to the therapeutic high potential contact 32c.

The main controller is shown in FIG. 6 when it is determined by the polarity conversion control process that the high voltage application is impossible in the high voltage application determination process, that is, when the pilot potential is applied to the lower electrode 25 and the upper electrode 26. Similarly, the connection converter 34 is controlled so that the voltage phases of the lower electrode 25 and the upper electrode 26 become in phase. In addition, when the main controller is determined to be capable of applying a high voltage in the high voltage application determination process, that is, when the therapeutic potential is applied to the lower electrode 25 and the upper electrode 26, as shown in FIG. The connection conversion part 34 is controlled so that the voltage phase of the electrode 25 and the upper electrode 26 may be reversed.

When the main control part becomes the therapeutic potential on the basis of the detected induced current, the current flows in the state in which the subject B is sitting in the chair 20 from Ir (Iq << Ir), from the chair 20. It is judged that the current Is (Is << Ir) which flows in the state where it is in the state where it is connected to the power supply 21 is determined, and it is determined that output interruption is necessary, and an output interruption determination process is performed. That is, the main controller determines that the output interruption is necessary when the induced current I becomes smaller than the predetermined current value Ib (for example, I = Ir) (I <Ib). Thereby, the main control part controls the conversion part 32, and converts into the OFF contact 32a from the high potential contact 32c for treatment.

The conversion unit 32 is provided on the primary side of the boost transformer 31, the OFF contact 32a for cutting the input, and the pilot potential contact 32b for generating a low voltage without risk of electric shock on the secondary side. And a therapeutic high potential contact 32c for generating a therapeutic high voltage (for example, 7000 V? 9000 V) on the secondary side. The safety resistor 33a is connected to one end of the secondary coil 31a of the boost transformer 31, and the other end is connected to earth. One end of the secondary coil 3lb is connected to the safety resistor 33b or earth via the connection converter 34, and the other end is connected to the earth or safety resistor 33b via the connection converter 34. Connected.

Next, with reference to FIG. 9, operation | movement of the electric potential treatment apparatus 17 of this embodiment is demonstrated. When the start switch is turned on (step SB11 (FIG. 9)), the main controller of the controller 29 is connected so that the voltage phases of the lower electrode 25 and the upper electrode 26 become in phase as shown in FIG. 6. The converter 34 is controlled (step SB12), and the converter 32 is controlled to convert from the OFF contact 32a to the pilot potential contact 32b. As a result, a pilot potential is applied to the lower electrode 25 and the upper electrode 26 (step SB13).

In this state, the to-be-treated person B sits in the chair 20 after standing to the electricity supply stand 21. In this state, as shown in FIG. 6, the electric current which flows along the path | route containing the secondary coil 31a, the upper electrode 26, the to-be-treated person B, the left electrode 24, and the electric current measuring part 28 ( Ic) and a current Id flowing along a path including the secondary coil 3lb, the lower electrode 25, the subject B, the left electrode 24, and the current measuring unit 28, the lower electrode ( 25 and the upper electrode 26 have the same polarity, so that they flow in the current measurement part 28 in the same direction. At this time, the current I flowing to the current measuring unit 28 becomes (| I | = | Ic + Id | = | Ic | + | Id |). As a result, when the lower electrode 25 and the upper electrode 26 have opposite polarities, (| I | = | Ic + Id | = || Ic |-| Id ||), the signals are canceled out. In the case of weakening, even a weak induction current is easily detected by the current measuring unit 28.

Next, in step SB14, the main controller determines whether the induced current exceeds Ia, and if the induced current exceeds Ia, proceeds to step SB15, and if the induced current is less than or equal to Ia, returns to step SB13. . That is, based on the detected induced current, the main controller determines that high voltage can be applied when it is determined that the current Ip is changed from the current Ip to the current Iq (Ip << Iq).

The main control part controls the connection conversion part 34 so that the voltage phase of the lower electrode 25 and the upper electrode 26 may be reversed in step SB15, and, in step SB16, as shown in FIG. The unit 32 is controlled to convert from the pilot potential contact 32b to the therapeutic high potential contact 32c. As a result, a therapeutic potential is applied to the lower electrode 25 and the upper electrode 26.

In this state, as shown in FIG. 7, the current which flows along the path | route containing the secondary coil 31a, the upper electrode 26, the to-be-treated person B, the left electrode 24, and the electric current measuring part 28 ( Ic) and a current Id flowing along a path including the secondary coil 3lb, the lower electrode 25, the subject B, the left electrode 24, and the current measuring unit 28, the lower electrode ( 25 and the upper electrode 26 are opposite polarities, flows to the current measuring unit 28 in the opposite direction.

Next, in step SB17, the main controller determines whether the current value is smaller than Ib, and if the current value is smaller than Ib, proceeds to step SA18, and returns to step SB16 if the current value is greater than or equal to Ib. . That is, the main control part is Is (Is << Ir) from the current Ir flowing in the state in which the to-be-treated B is sitting in the chair 20, when it becomes a therapeutic potential based on the detected induced current. If it is determined that the signal is changed to 0, it is determined that the output interruption is necessary.

In step SB18, the main control unit controls the conversion unit 32 to convert from the therapeutic high potential contact 32c to the OFF contact 32a. This cuts off the output.

According to the configuration of the second embodiment, first, the pilot potential without the risk of electric shock is applied to the power supply table 21, the induced current in the left electrode 24 is measured, and the chair of the subject B is treated. It is determined whether or not a high voltage is applied in accordance with the change in the current value accompanying the seating on 20), and when it is determined that the high voltage can be applied, a high voltage for treatment is applied to the current carrying plate 21, so In this case, the subject B is not insulated, and safety can be ensured.

In addition, since the subject B determines whether or not the output interruption is necessary according to the change in the current value accompanying the fall from the chair 20, and the output interruption is shut off when it is determined that the output interruption is necessary, the potential treatment device ( In the case of descending from 18), it is possible to ensure safety without causing the subject B to be insulated. Therefore, the insulator which has been used conventionally is not required, and the configuration can be simplified.

In addition, since the subject B determines whether or not the output blocking is necessary according to the change in the current value accompanying the fall from the chair 20, and the output blocking is cut off when it is determined that the output blocking is necessary, the treatment B is not being treated. Nevertheless, since no high voltage is applied, deterioration of the potential treatment device 17 can be prevented and the life can be extended.

When the pilot potential is applied to the lower electrode 25 and the upper electrode 26, the connection converter 34 is controlled so that the voltage phases of the lower electrode 25 and the upper electrode 26 are in phase. When the therapeutic potential is applied to the lower electrode 25 and the upper electrode 26, the connection converter 34 is controlled so that the voltage phases of the lower electrode 25 and the upper electrode 26 are reversed. Therefore, when the pilot potential is applied, the current Ic flowing along the path including the secondary coil 31a, the upper electrode 26, the subject B, the left electrode 24, and the current measuring unit 28. ) And a current Id flowing along a path including the secondary coil 3lb, the lower electrode 25, the subject B, the left electrode 24, and the current measuring unit 28, are currents in the same direction. It flows to the measurement part 28.

Therefore, the current I flowing to the current measuring unit 28 becomes (| I | = | Ic + Id | = | Ic | + | Id |), and even the weak induction current is easily performed by the current measuring unit 28. And reliably detected. Therefore, the precision of the detection of the seat of the to-be-treated B can be improved.

When the therapeutic potential is applied to the lower electrode 25 and the upper electrode 26, the connection converter 34 is controlled so that the voltage phases of the lower electrode 25 and the upper electrode 26 are reversed. Therefore, a sufficient potential difference for the treatment can be ensured.
