DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. First, FIG. 1 shows a system configuration of a potential therapy device. In FIG. 1, reference numeral 1 denotes a potential therapy device;
Is an insulating sheet laid on the floor. The energizing sheet 3 is connected to the potential treatment device 1 via a cable 4,
Is placed directly on the insulating sheet 2 or on a chair 5 or the like on the insulating sheet 2 and the user sits on the conductive sheet 3,
The human body in contact with the conductive sheet 3 has a high potential of several thousand volts with respect to the ground. In the figure, reference numeral 6 denotes an insulating mat for placing a foot.

FIG. 2 shows a circuit block of the electric potential therapy device 1, 11 is a control unit, and 12 is a step-up transformer. One end of the secondary winding of the step-up transformer 12 is a resistor 1
3, and the other end is connected to the primary side circuit via a resistor 14 of more than 10 M ohms.

The control unit 11 includes a microcomputer 15
And an inverter circuit 16. An operation circuit board 17 is connected to the microcomputer 15.

The operation circuit board 17 has a voltage setting button 1
8 and a frequency setting button 19, a plurality of operation buttons for electric potential treatment, such as a start button, a stop button, a timer button, and an automatic course setting button, which are not shown, are provided. The value is displayed on the display.

Since the output voltage and the output frequency of the inverter circuit 16 can be changed almost steplessly by the control voltage, the output voltage of the step-up transformer 12 is increased by the voltage setting button 18 in the range of 3000 V to 9000 in 500 V steps. Change or frequency setting button 1
9, the output frequency of the step-up transformer 12 can be changed stepwise from a low frequency close to DC to a high frequency of several tens kHz or more. By appropriately changing the output voltage and the output frequency, it is possible to prevent a decrease in the therapeutic effect due to the familiarity with the same stimulus.

Each time the timer button is pressed, the treatment time setting changes to 20 minutes, 40 minutes, and 60 minutes.
If the voltage is set to 6000 V for 0 minute and the start button is pressed, the boosting transformer automatically stops after outputting 6000 V for 20 minutes.

When the automatic course selection button is pressed, for example, 2
An automatic course in which the output voltage changes stepwise during one cycle set to 0 minutes is executed. The program memory of the control unit 11 stores a plurality of output pattern programs each having a different voltage change pattern as an automatic course, and an arbitrary automatic program can be selected. By driving the step-up transformer 12 by the inverter circuit 16, the output voltage can be changed in more steps than in the conventional potential therapy device, so that it is possible to set an extremely large variety of voltage change pattern programs.

FIG. 3 is a circuit diagram of the circuit shown in FIG.
0 is provided, and the output voltage of the step-up transformer 12 is feedback-controlled. The output of the output voltage detection circuit 20 that detects the voltage at the output terminal of the potential therapy device 1 is input to the microcomputer 15, and the microcomputer 15 controls the inverter circuit 16 so that the output voltage matches the set voltage.

Accordingly, even if a weak current leaks to the ground when the insulation between the conductive sheet 3 and the ground is poor,
Since the output voltage to the energizing sheet 3 is controlled so as to be equal to the set voltage, the decrease in the output voltage due to the leakage of the current can be compensated, and the decrease in the potential therapeutic effect can be prevented. Can be given.

The present invention is not limited to the above-described embodiment, and various modifications are possible within the technical scope of the present invention, and it goes without saying that the present invention extends to those modifications. is there.

[0018]

As described above, the potential therapy device of the present invention is configured so that the switching of the output voltage of the step-up transformer is electronically controlled by the inverter circuit. The need for a step-up transformer with an intermediate tap is eliminated, enabling the use of a small step-up transformer and switching the output voltage in multiple stages.
This is effective for reducing the size and weight of the electric potential therapy device and improving the function.

Further, by controlling the output voltage of the step-up transformer to match the output voltage with the set voltage, the output voltage is maintained at the set voltage regardless of a change in the degree of insulation with respect to the ground. It can exert a therapeutic effect.
