Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention dielectricizes high voltage to the human body,
The present invention relates to an electric potential treatment device used for treating headache, stiff shoulder, insomnia, chronic constipation and the like.

[0002]

2. Description of the Related Art A potential treatment device is a treatment device for inducing a high voltage in a human body by using a high voltage generating transformer that has been subjected to a primary and secondary high voltage insulation process. It is known that sufficient safety measures are required.

As shown in FIG. 3, a protective resistor is installed in order to prevent electric shock due to overcurrent. The protective resistor 42 ″ is short-circuited to the ground on the input side of the protective resistor 41 ″. In the case of occurrence of the electric current, the leakage current from the primary side of the high voltage transformer 2 ″ is controlled, and the protection resistor 41 ″ is connected to the energizing electrode 3
This is to protect the human body from electric shock by preventing overcurrent from the secondary side of the high voltage transformer 2 "when a short-circuit accident occurs due to the breakdown of the insulation sheet 32" for ground insulation of 1 ". Yes, these two separate protective resistors 42 ",
Since 41 ″ is formed by being mounted on the substrate installed outside the high voltage transformer 2 ″, the risk of the above-mentioned short circuit accident occurring over time on the wiring is not 0%. It was installed to raise it as much as possible.

At the time of treatment, the human body is brought into contact with the current-carrying sheet 3 "composed of the current-carrying electrode 31" and the insulating sheet 32 "to induce a high voltage in the human body. Current-carrying electrode 3 to prevent arc discharge to ground
The 1 ″ had to be covered with a high voltage insulation film.

[0005]

Disadvantages of the prior art However, when the energizing sheet is brought into contact with the human body, the energizing sheet is almost equal to the ambient temperature, so that the person applying the electric potential therapy device is cold when the temperature is low. It had the drawback of giving pain.

[0006] Therefore, if a heater is separately provided from the commercial power source by electric heating in the vicinity of the energizing electrode 31 ″ to keep the energizing electrode warm, the high voltage side approaches the low voltage side, which causes insulation failure. However, there is a high risk that the voltage of the energizing electrode will drop and it was difficult to commercialize.

Further, in order to maintain the insulation in order to prevent the voltage drop of the current-carrying electrode, the distance between the current-carrying electrode and the heater is required, and the current-carrying sheet including the current-carrying electrode, the heater and the insulating film is required. It becomes too thick to be installed directly below the supine human body.

[0008]
