JP 2017-038836 A

  By the way, from the viewpoint of safety, the value of the leakage current from the lead portion is defined in the JIS standard in the potential treatment apparatus 100.

  Therefore, a protective resistor (not shown) is provided on the output side of the high-voltage transformer 109 of the potential treatment apparatus 100, and the leakage current from the current-carrying parts (conductor parts) 103 and 104 becomes "JIS or less". It is like that.

  If the leak current is large, the subject H feels a strong feeling of chatter. Since this chatty feeling may cause fear of electricity, current, electric field, etc. depending on the person, in practice the leakage current value will be relatively weaker than the maximum value of the JIS specified value. It is often set.

  The sense of freedom is one of the bodily sensations being treated in the potential treatment apparatus 100, and the subject H can feel even in the usual treatment, but the subject H can feel the body against the surrounding wall (ground) etc. When the part of the body H is brought close, the subject H feels a stronger feeling as "light" due to the light discharge phenomenon that occurs between the wall and the body part.

  This is because the potential of the human body of the subject H is increased when treating with the potential treatment apparatus 100, and a potential difference is generated with the surrounding wall or the like.

  Then, when the value of the output current of the high voltage transformer 109 is large, the value of the leakage current of the energizing units 103 and 104 is large, and the human potential of the subject H becomes high. Conversely, when the value of the output current of the high voltage transformer 109 is small, the potential of the human body is low.

  Further, the human potential of the subject H is inversely proportional to the distance (interval) between the electrodes 112 and 113 of the current-carrying parts 103 and 104 and the subject H, and the human potential is low when the distance is large. When the distance is short, the potential of the human body is high.

  The sense of freedom is different depending on the person, and may differ depending on the environment where the potential treatment apparatus 100 is placed, such as humidity and temperature.

  In addition, long-term potential treatment may cause habituation, which may make it difficult to feel a sense of freedom.

  On the other hand, the electric field generated by the electric potential treatment apparatus 100 is invisible, and depending on the subject H, it is recognized that "being treated" by the above-mentioned "crisp feeling". And sometimes close to

  Then, when it comes to feel that the feeling of liberty has become weak (by the environment, getting used to etc.), the subject H may misidentify that the potential treatment apparatus 100 is broken.

  Therefore, an object of the present invention is to provide a potential treatment apparatus capable of adjusting the value of the leakage current from the electrode.

  In order to solve the above problems, the invention according to claim 1 comprises a high voltage transformer for boosting an input voltage to generate a high voltage, an electrode to which a high voltage generated by the high voltage transformer is applied, and the high voltage transformer And a protective resistor connected between the electrode and the electrode to suppress the value of leakage current from the electrode, and applying a high voltage to the treatment subject to treat in a state where the electrode is insulated The potential treatment apparatus is characterized in that adjustment means is provided for adjusting the value of the leak current from the electrode.

  Further, the electric potential therapy device 1 has the power plug 15, the main switch 16, the output switch 17, the AC / DC converter 18, and the high voltage transformer as an internal functional configuration as in the electric potential therapy device 100 of FIG. A microcomputer 19, an operation unit 21, electrodes 22 and 23, and an LED 24 are provided, and an adjustment device (adjustment unit) 25 is further provided. That is, the point that the potential treatment apparatus 1 according to the first embodiment differs from the conventional potential treatment apparatus 100 illustrated in FIG. 6 is that the adjustment apparatus 25 is provided. In addition, the point that the high voltage of a reverse phase is applied to the electrodes 22 and 23 is the same as that of the said conventional electric potential treatment apparatus 100. FIG.

  The adjusting device 25 is a device for adjusting the leakage current from the electrode 22 located above the head of the subject H and the electrodes 22 and 23 located below the foot of the subject H, and includes the high voltage transformer 19 and the electrode 22. , 23 are connected. In addition, although the adjustment apparatus 25 can be connected to either or both of the electrodes 22 and 23, here, about what connects the adjustment apparatus 25 to the electrodes 22 and 23 located under a to-be-treated person's H foot explain.

  FIG. 2 is a circuit diagram showing the high voltage transformer 19 and the adjusting device 25 of FIG.

  The high voltage transformer 19 is a device that applies a high voltage to the electrodes 22 and 23, generates a voltage by electromagnetic induction, and boosts the voltage according to the number of turns of a coil.

  An adjustment means 25 is provided at a stage subsequent to the high voltage transformer 19 via a protection resistor 26. In this adjustment means 25, an adjustment resistor 251 having a predetermined resistance value and a bypass line 252 are connected at a stage subsequent to the protection resistor 26. The first output terminal 253 is provided downstream of the adjustment resistor 251, and the second output terminal 254 is provided downstream of the bypass line 252.

  The protective resistor 26 is for causing the leakage current from the electrodes 22 and 23 to be equal to or less than the specified value of JIS as described in the conventional electric potential treatment apparatus 100 described above.

  The second output terminal 254 is connected to the middle portion of the protection resistor 26 and leaks more current than the first output terminal 253. Therefore, when the electrodes 22 and 23 are connected to the second output terminal 254, the value becomes equal to or less than the specified value of JIS.

  Therefore, in the potential treatment apparatus 1 according to the first embodiment, since the first output terminal 253 and the second output terminal 254 having different values of the output current are provided, the electrodes 22 and 23 are selectively selected. By connecting to the output terminal 253 or 254, the value of the leakage current from the electrodes 22, 23 can be adjusted.

  That is, in the case where the electrodes 22 and 23 are connected to the first output terminal 253 of the electric potential treatment device 1, the feeling of weakness is somewhat weak, and in the case where the electrodes 22 and 23 are connected to the second output terminal 254 You will feel a little stronger.

  Therefore, if the treatment subject H does not want to feel a sense of chatty so much, the electrodes 22 and 23 are connected to the first output terminal 253, and if it is desired to feel a sense of chatter more strongly Connecting.

  As described above, in the potential treatment apparatus 1 according to the present invention, when the potential treatment apparatus 1 is used in a state where the electrodes 22 and 23 are connected to the first output terminal 253, a "crisp feeling" of a predetermined strength is obtained. If the potential treatment apparatus 1 is used in the state of being connected to the second output terminal 254 while it is felt, it is possible to feel a more “crisp feeling” than in the state of being connected to the first output terminal 253.

  Therefore, when the treatment subject H gets used to the "strong feeling" of a predetermined strength, by replacing the wiring connected to the electrodes 22 and 23 with the second output terminal 254, a stronger feeling "strongness" Since it is possible to feel the "feeling" by electrical stimulation, it is possible to perform a more satisfactory treatment.

  Further, since the adjusting device 25 includes the adjusting resistor 251, the bypass line 252, and the output terminals 253 and 254, it is possible to adjust the value of the leakage current with a simple configuration.

  In the first embodiment, although only one bypass line 252 is provided, a plurality of bypass lines are provided, and an output terminal is directly provided in a subsequent stage, and one of them is provided in another bypass line. If adjustment resistors of different resistance values are respectively provided, it becomes possible to adjust the value of the leakage current of the electrodes 22 and 23 in a plurality of steps.

  In this case, the electrodes 22 and 23 may be selectively connected to one of the output terminals 253, 254,... To selectively increase or decrease the value of the leakage current from the electrodes 22 and 23. The subject H can choose a different sense of intensity.
