  By the way, since an electric potential treatment apparatus applies and uses a high electric potential, at the time of use, attention to a to-be-treated person is desired. For example, if a pilot lamp or the like for indicating that a high potential is applied is provided near the treatment electrode in order to call attention to the patient, the patient will receive a high potential. Can be easily determined.

  However, since the pilot lamp is an electronic element that operates at a low voltage (low-voltage operating element), in order to provide the pilot lamp near the therapeutic electrode, a high degree of electrical insulation is required. That is, since a high voltage of several thousand volts or more is applied to the therapeutic electrode of the potential therapy device by a high voltage transformer, an electronic circuit using a general electronic element used at a low voltage is placed near the therapeutic electrode. However, if a low-voltage power supply by supplying power from a commercial power supply is not insulated from a high voltage, dielectric breakdown or leakage occurs, and there is a problem in that commercialization involves technical difficulties. Therefore, in the past, the primary side voltage of the high voltage transformer must be used to indirectly display the actual high voltage generation.

  Therefore, in the past, in order to indicate that a high potential is applied, the energization state on the primary side of the high-voltage transformer must be displayed with a pilot lamp, and whether or not a high potential is generated is directly indicated. The display was not correct.

  In addition, in the potential treatment device, there is a case where it is desired to provide a low potential operation element in order to realize a heater and other functions (massage function or the like).

  Therefore, an object of the present invention is to provide a potential treatment device that can easily obtain a low-voltage power supply from the secondary side of a high-voltage transformer without requiring high-level electrical insulation.

  According to the present invention, a high voltage is applied to the treatment electrode via the high potential output terminal of the high voltage transformer, and the low voltage operating element has a low potential difference with respect to the high potential output terminal and the output terminal. It operates by the voltage with the output terminal.

  According to a second aspect of the present invention, in the potential treatment device according to the first aspect, the high voltage transformer includes a high potential winding for inducing a high voltage on the secondary side and a low voltage adjacent to the high potential winding. The high-potential winding and the low-voltage winding are connected via a high impedance element.

  According to a third aspect of the present invention, in the potential treatment device according to the first or second aspect, the low-voltage operating element is a pilot lamp that is turned on when a high voltage is applied to the therapeutic electrode. .

  According to the first aspect of the present invention, since a plurality of output terminals having different potentials are formed on the secondary side of the high-voltage transformer, it is possible to obtain a low-voltage power source using a potential difference between the output terminals. It is possible to operate a low-voltage operating element for alerting without requiring an electrical insulation.

  According to the invention described in claim 2, since the high potential winding and the low voltage winding are connected via the high impedance element, it is possible to prevent the current exceeding the allowable value from flowing to the treatment electrode. And the risk of electric shock can be reduced.

  According to the third aspect of the present invention, since the low voltage operating element is a pilot lamp that is turned on when a high voltage is applied to the therapeutic electrode, the high voltage applied to the therapeutic electrode can be easily determined visually and used. It is possible to increase the alert for high voltage during the time.

As shown in FIG. 2, the electric potential treatment device 1 mainly includes a chair 2 on which the patient C sits, a footrest 3 on which the foot can be placed when the patient C sits on the chair 2, and is built in the footrest 3. A treatment electrode 4 for setting the treatment subject C to a high potential and a high voltage generation unit 5 for supplying a high voltage to the treatment electrode 4 are provided.

  The chair 2 includes a seat portion 21, a backrest 22, and left and right sidewalls 24 and 24, all of which are covered with an insulator (surface layer material). A remote controller 27 is provided on the upper surface of the sidewall 24.

  The footrest 3 is disposed on the floor surface F in front of the seat portion 21.

In addition, the footrest 3 is provided with a pilot lamp 6 as a low-voltage operating element that enhances alerting to a high voltage.

  FIG. 1 shows a high voltage generating unit 5. The high voltage generation unit 5 has a high voltage transformer 51. A primary winding 51b, a high potential winding 51c and a low voltage winding 51d as a secondary winding are wound around the iron core 51a of the high voltage transformer 51. The primary winding 51 a is connected to the commercial power supply V via a switch housed in the remote controller 27. The low voltage winding 51d is disposed adjacent to the high potential winding 51c.

  One end of the high potential winding 51 c of the high voltage transformer 51 is connected to one end of the primary side winding 51 b, and the other end is connected to the first output terminal 53 via the high impedance element 55.

  One end of the low voltage winding 51 d of the high voltage transformer 51 is connected to the first output terminal 53, and the other end (the end opposite to the high impedance element 55) is connected to the second output terminal 52. .

  Thus, two output terminals 52 and 53 having different potentials are formed on the secondary side of the high-voltage transformer 51, and the first output terminal 53 applies a high therapeutic potential. And an output terminal for applying a predetermined voltage between the first output terminal 53 and the second output terminal 52.

The therapeutic electrode 4 is applied to 9000 V, the patient C is set to a high potential, and an electric field is formed around the human body of the patient C, and treatment is performed by this electric field.

  In this state, since the potential difference between the potential E1 of the first output terminal 53 and the potential E2 of the second output terminal 52 is 10 V, the pilot lamp 6 can be turned on by this potential difference. That is, in this embodiment, since a low voltage power source is obtained by utilizing the potential difference between the plurality of output terminals on the secondary side of the high voltage transformer 51, high-level electrical insulation is not required. The pilot lamp 6 which is a low-voltage electronic element can be turned on.

  As described above, since the potential treatment device 1 is used in a state where a high voltage is applied, by providing the pilot lamp 6 near the treatment electrode in order to alert the treatment subject C, the treatment subject C Visual application of a high voltage to the treatment electrode 4 can be easily determined by visual observation, and alerting to a high voltage during use can be enhanced.
