Since each of the potential treatment devices includes the synchronization input terminal 9 and the synchronization output terminal 10, a plurality of potential treatment devices can be connected in series with respect to the synchronization signal.

  FIG. 2 is a time chart showing an example of the synchronization signal. FIG. 2A is an example of the analog synchronization signal I indicating an output voltage of 9000 [V] and a frequency of 50 [Hz].

  FIG. 5 is a schematic block diagram for explaining the configuration of a second embodiment of the potential treatment device according to the present invention. The potential therapy device includes a high-voltage cable connected to the high-voltage output terminal and a current-carrying sheet connected to the tip of the high-voltage cable, but these are not directly related to the gist of the present invention, and those skilled in the art Since it is a well-known thing, illustration is abbreviate | omitted.

  In FIG. 5, the potential therapy device of the second embodiment includes a control panel 1 to which settings such as a timer time, an output voltage, and a frequency are operated and input, a voltage and frequency set from the control panel 1, and a power supply phase detection described later. Based on the phase detected by the circuit 13, the microcomputer 2 which is a synchronous control circuit for controlling the frequency, voltage and phase of the AC high voltage output from the high voltage output terminal 11, and an AC commercial power source serving as a power source for the potential therapy device An AC plug 3, a power switch 4, a rectifying circuit 5 for rectifying an alternating current obtained from an alternating-current commercial power source and supplying the rectified current to the microcomputer 2 and the drive circuit 6, a frequency designated by the microcomputer 2, A drive that drives the primary side of the high voltage transformer 7 so as to output an alternating high voltage of voltage and phase from the high voltage output terminal 11.

  When the frequency set from the control panel 1 is equal to the frequency of the AC commercial power supply, the microcomputer 2 synchronizes the control signal output to the drive circuit 6 with the phase detected by the power supply phase detection circuit 13. As a result, the phase of the AC commercial power supply and the phase of the AC high voltage of the high voltage transformer 7 driven by the drive circuit 6, in other words, the phase of the AC high voltage output from the high voltage output terminal 11 coincides or is a constant phase. It becomes a relationship.

If there is a potential therapy device that does not match, the phases are matched by pulling out the AC plug 3 and reconnecting it with the reverse polarity.

  According to the present embodiment, when a frequency equal to the frequency of the AC commercial power supply is selected as the output frequency of the potential therapy device, the phase of the AC high voltage output is matched without transmitting a synchronization signal between the plurality of potential therapy devices. There is an effect that can be made.

  FIG. 6 is a schematic block diagram for explaining the configuration of a third embodiment of the potential treatment device according to the present invention. This embodiment is a combination of the first embodiment and the second embodiment. That is, the power source phase detection circuit 13 of the second embodiment is added to the configuration of the first embodiment shown in FIG. Since other configurations are the same as those in FIG. 1, the same components are denoted by the same reference numerals and redundant description is omitted.

  Connected to the microcomputer 2 are a control panel 1, a synchronization input terminal 9, a synchronization output terminal 10, a drive circuit 6 and a power supply phase detection circuit 13. As in the first embodiment, the slave mode is set when a synchronization signal is input from the synchronization input terminal 9 and the master mode is set when no synchronization signal is input.

  However, in the master mode, when the frequency set from the control panel 1 is equal to the frequency of the AC commercial power supply, the microcomputer 2 synchronizes the control signal output to the drive circuit 6 with the phase detected by the power supply phase detection circuit 13. . As a result, the phase of the AC commercial power supply and the phase of the AC high voltage of the high voltage transformer 7 driven by the drive circuit 6, in other words, the phase of the AC high voltage output from the high voltage output terminal 11 coincides or is a constant phase. It becomes a relationship.

  When a plurality of potential treatment devices according to the present embodiment are arranged, when a synchronization signal is not connected between the plurality of potential treatment devices, the same operation as in the second embodiment is performed, and the potential is controlled by the control panel 1 of each potential treatment device. When a frequency equal to the frequency of the AC commercial power supply is selected as the frequency of the AC output of the treatment device, the output phase of each potential treatment device matches. If there is a potential therapy device that does not match, the phases are matched by pulling out the AC plug 3 and reconnecting it with the reverse polarity.

  In addition, when a plurality of potential treatment devices according to the present embodiment are arranged, when a synchronization signal is connected between a plurality of potential treatment devices, the operation is the same as that of the first embodiment.

  That is, the potential therapy device to which no synchronization signal is input is in the master mode. The remaining potential treatment devices to which the synchronization signal is input are in the slave mode. Since the frequency, voltage and phase of the potential therapy device in the master mode are transmitted to the potential therapy device in the slave mode via the synchronization signal, the frequency, voltage and phase of the high voltage output of the potential therapy device in the slave mode are transferred to the potential therapy in the master mode. Can be matched to the frequency, voltage and phase of the vessel. Thereby, the potential difference of the high voltage output between the adjacent potential treatment devices can be eliminated, the discharge when the treated persons approach each other can be prevented, and the treated person can be prevented from feeling discomfort and fear.
