The high voltage generating circuit 2 boosts the power supply voltage output from the power supply circuit 1 to a voltage necessary for the potential treatment (for example, an effective value of 300 V to 9000 V), and generates a boosted voltage, that is, a high voltage circuit.

Here, it is assumed that the high voltage generating circuit 2 boosts the power supply voltage output from the power supply circuit 1, but may boost the voltage of a different frequency generated from the power supply voltage.

Further, the power supply circuit 1 and the high voltage generating circuit 2 constitute a voltage generating mechanism.

The method of generating the high voltage of the high voltage generating circuit 2 is not particularly limited, and a transformer boosting method can generally be used.

In the transformer boosting mode, if the high voltage generating circuit 2 is equipped with a transformer and an alternating voltage waveform of about several tens of volts to about 100 volts is input to the primary side of the transformer, a high voltage of 9000 V or less can be generated from the secondary side of the transformer.

As the conductive electrode plate of the current-carrying mat 3, for example, a carbon electrode made of carbon cloth, carbon fiber or the like can be used.

As the insulating material of the current-carrying felt 3, for example, vinyl chloride or the like can be used.

In addition, by sandwiching the conductive electrode plate with an insulating material and performing a withstand voltage treatment on the outer periphery, the inner conductive electrode plate is insulated from the therapist, and the therapeutic person can be safely added with a high potential.

The insulating sheet 4 is for suppressing the voltage drop applied to the therapist It is used low, and as a material of the insulating sheet 4, vinyl chloride or the like which is easy to process can be used.

The liquid crystal display device 5 is provided in an electrically non-grounded state (or the touch panel 6 mounted on the surface is electrically ungrounded), and displays various voltage values or treatment elapsed time given to the current healer. Information device. The liquid crystal display device 5 is, for example, a unit device including a dot matrix type liquid crystal display, a microcomputer that drives the liquid crystal display, a memory device, a control circuit, a backlight circuit, and the like.

The touch panel 6 is a human-machine interface that accepts the operation of the therapeutic device and is attached to the surface of the liquid crystal display device 5.

That is, the touch panel 6 is a thin transparent panel mounted on the surface of the liquid crystal display device 5. For example, when the therapist touches the surface of the touch panel 6 with the fingertip, the X coordinate at which the touch position is displayed is implemented. The electrical signal with the Y coordinate is output to the control IC in the liquid crystal display device 5.
