Fig. 2 is a view showing the configuration of a potential therapeutic device according to a second embodiment of the present invention.

Embodiment 1.

Fig. 1 is a view showing the configuration of a potential therapeutic device according to a first embodiment of the present invention.

In FIG. 1, the power supply circuit 1 is connected to a commercial power source, and a power supply voltage of, for example, 100 V supplied from the commercial power supply is output to a circuit of the high voltage generating circuit 2.

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 it is also possible to boost the voltage of the 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 a high voltage by the high voltage generating circuit 2 is not particularly limited, but 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. Voltage.

Further, the high voltage generating circuit 2 is provided with a current limiting resistor that suppresses an output current below a specific reference current, and outputs the generated high voltage to the current-carrying pad 3 via the current limiting resistor.

The current-carrying mat 3 is covered with an insulating material to cover a mat of a conductive electrode plate to which a high voltage generated by the high-voltage generating circuit 2 is applied, and the current-carrying mat 3 is placed under a therapeutic person who receives the potential treatment.

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. Potential therapy.

The insulating sheet 4 is laid between the current-carrying felt 3 and the floor, and cuts off the current flowing from the current-carrying felt 3 to the ground. The insulating sheet 4 is used to suppress a voltage drop applied to the treatment person, and as the 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 a device that displays various information such as a voltage value or a treatment elapsed time given to the current healer. 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.

Further, the liquid crystal display device 5 is also provided with a control IC that transmits an electrical signal (coordinate information indicating the contact position of the therapist) output from the touch panel 6 to the control circuit.

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 indicating the touch position is implemented. The electrical signal with the Y coordinate is output to the control IC in the liquid crystal display device 5.

The induced voltage detecting circuit 8 is connected to the liquid crystal display device 5 via the resistor 7, and detects a circuit in which the voltage is induced by the liquid crystal display device 5 as the therapist present on the current-carrying pad 3 approaches.

The voltage control circuit 9 performs control for lowering the voltage value of the high voltage generated by the high voltage generating circuit 2 when the voltage detected by the induced voltage detecting circuit 8 is higher than a preset upper limit voltage (to lower the voltage) The control of the voltage value of the voltage also includes the control of stopping the output of the high voltage).

Further, after the voltage control circuit 9 performs the control for reducing the voltage value of the high voltage generated by the high voltage generating circuit 2, if the therapist present on the current-carrying pad 3 is released, the therapeutic person touches it. When the control panel 6 loses the operation signal output from the touch panel 6, the control for lowering the voltage value of the high voltage generated by the high voltage generating circuit 2 is released after the operation signal disappears for a certain period of time (the implementation is improved to Reduce the control of the previous voltage value).

The insulated communication circuit 10 is a circuit that transmits and receives signals exchanged between the voltage control circuit 9 and the liquid crystal display device 5 in a state in which the voltage control circuit 9 is electrically insulated from the liquid crystal display device 5.

As a signal transmitted from the voltage control circuit 9 to the liquid crystal display device 5, for example, a signal indicating a voltage value of a high voltage generated by the high voltage generating circuit 2 can be considered, and the liquid crystal display device 5 can display by receiving the signal. The voltage value of the high voltage generated by the high voltage generating circuit 2 is generated.

As a signal transmitted from the liquid crystal display device 5 to the voltage control circuit 9, for example, a signal indicating a set voltage value of a high voltage received by the touch panel 6 or a set time of a treatment time may be considered, and further, it may be considered The operation signal in the operation of the touch panel 6. The voltage control circuit 9 can control the voltage value of the high voltage generated by the high voltage generating circuit 2, the output time of the high voltage, and the like by receiving the signal.

Further, the power supply circuit 1, the high voltage generating circuit 2, the liquid crystal display device 5, the touch panel 6, the induced voltage detecting circuit 8, and the voltage control circuit 9 are formed into a housing. The body device is constructed, for example, as a desktop frame.

Next, the action will be explained.

The power supply circuit 1 is connected to a commercial power source, and outputs a power supply voltage of, for example, 100 V supplied from a commercial power supply to the high voltage generating circuit 2.

The high voltage generating circuit 2 boosts the power supply voltage to a voltage necessary for the potential treatment (for example, an effective value of 300V to 9000V) when receiving the power supply voltage from the power supply circuit 1, and generates a boosted voltage (hereinafter referred to as It is "high voltage").

The high voltage generating circuit 2 outputs the high voltage to the current-carrying mat 3 when a high voltage is generated. However, for example, in the Japanese Pharmaceutical Law, it is prescribed that a high voltage is applied to the therapist in order to ensure the safety of the therapist. The leakage current (for example, the current flowing from the therapeutic device to the ground by the therapist) is suppressed to a certain reference value or less, so that the generated high voltage is output to the current-carrying felt 3 via the current-limiting resistor attached thereto.

The current-carrying felt 3 is composed of an inner conductive electrode plate and an insulating material covering the conductive electrode plate, and a high voltage output from the high-voltage generating circuit 2 is applied to the conductive electrode plate of the current-carrying pad 3.

Since the therapist receives the potential treatment, it is located on the conductive pad 3 to which the high voltage is applied (in the example of FIG. 1, the therapist is standing on the electrifying mat 3, and may be in a state of sitting or lying down). It will give a high potential to the body of the healer.

In addition, an insulating sheet 4 is laid between the electric insulating mat 3 and the floor, and the insulating material is used. The conductive electrode plate of the current-carrying pad 3 is covered, so that the current flowing from the current-carrying pad 3 to the ground is cut off, and the voltage drop applied to the therapist can be suppressed.

In the first embodiment, since the touch panel 6 is mounted on the surface of the liquid crystal display device 5, the therapist can perform the operation of the therapeutic device with the touch panel 6 while observing the display content of the liquid crystal display device 5 (for example, It is excellent in operability or convenience, such as ON (open) / OFF (off) of the therapeutic device, variable voltage value of the high voltage, setting of the treatment time, and the like.

However, since the body of the therapist is subjected to a high potential (in the therapeutic treatment, the maximum induction is equal to the high voltage generated by the high voltage generating circuit 2), the induced voltage described below is not installed. When the detecting circuit 8 or the voltage control circuit 9 touches the touch panel 6, the discharge or vibration is generated by the potential difference between the therapist and the touch panel 6 (the liquid crystal display device 5). In the first embodiment, since the induced voltage detecting circuit 8 or the voltage control circuit 9 is mounted, it is possible to prevent the occurrence of discharge or vibration.

The induced voltage detecting circuit 8 detects the liquid crystal display device 5 applied to the state in which it is insulated from the power supply circuit 1, and detects the voltage V induced by the liquid crystal display device 5 as the therapist present on the current-carrying pad 3 approaches.

For the treatment in the treatment, as described above, since the maximum induction is equal to the high voltage generated by the high voltage generating circuit 2, when the therapist approaches the touch panel 6 by hand, the self-therapist actually touches The voltage applied to the liquid crystal display device 5 gradually rises from the stage before the touch panel 6 is touched.

The voltage control circuit 9 compares the voltage V with a preset upper limit voltage Vth when the induced voltage detecting circuit 8 detects the voltage V induced by the liquid crystal display device 5.

The upper limit voltage Vth is set to be higher than the voltage of the therapeutic person who is not in contact with the touch panel 6 by the treatment, and is lower than the voltage of the treatment subject actually touching the touch panel 6 (to be less susceptible to discharge, etc.) The conditions caused by the discomfort or the conditions such as the failure of the device caused by the discharge are appropriately determined.

The voltage control circuit 9 is for reducing the voltage generated by the high voltage generating circuit 2 when the voltage V detected by the induced voltage detecting circuit 8 is higher than the upper limit voltage Vth (V≧Vth). The control signal of the value is output to the high voltage generating circuit 2, and the control for stopping the generation of the high voltage is also included in the control for lowering the voltage value of the high voltage.

The high voltage generating circuit 2 is configured to reduce the voltage value applied to the high voltage of the current energizing mat 3 (or stop the generation of the high voltage) when receiving a control signal for lowering the voltage value of the high voltage from the voltage control circuit 9. The way to do it.

According to this operation, since the potential difference between the therapist and the touch panel 6 is lowered, even if the therapist in the treatment touches the touch panel 6, the discharge or vibration due to the fingertip of the therapist can be suppressed.

The voltage control circuit 9 is configured to monitor the operation signal output from the touch panel 6 while the user operates the touch panel 6 after the high voltage generating circuit 2 lowers the voltage value of the high voltage, and outputs the operation signal from the touch panel 6 When the signal is judged to end, the control for restoring the voltage value of the high voltage generated by the high voltage generating circuit 2 to the original voltage after a certain time has elapsed since the operation signal is not output (for example, one second later) The signal is output to the high voltage generating circuit 2.

The high voltage generating circuit 2 is configured to increase the voltage value applied to the high voltage of the current power supply pad 3 to the lower limit before receiving the control signal for returning the voltage value of the high voltage to the original voltage from the voltage control circuit 9. The voltage value is operated in a manner.

Since this action applies a high potential to the body of the healer, the potential treatment can be continued.

Further, even if the high potential applied to the body of the therapist temporarily decreases, as long as the period is short, there is no problem in terms of the therapeutic effect.

The insulated communication circuit 10 has a function of transmitting and receiving signals exchanged between the voltage control circuit 9 and the liquid crystal display device 5.

For example, when the output of the voltage control circuit 9 indicates that the current high voltage generating circuit 2 is generated The instant signal of the high voltage voltage value, voltage waveform, frequency, etc., is transmitted to the liquid crystal display device 5 by the insulated communication circuit 10.

The liquid crystal display device 5 displays a voltage value, a voltage waveform, a frequency, and the like of a high voltage generated by the high voltage generating circuit 2 by receiving the signal.

Further, for example, when the liquid crystal display device 5 outputs an operation signal indicating a set voltage value of a high voltage received by the touch panel 6, or a set time of a treatment time, etc., the insulated communication circuit 10 transmits the operation signal to the voltage control circuit. 9.

The voltage control circuit 9 controls the voltage value of the high voltage generated by the high voltage generating circuit 2, the output time of the high voltage, and the like by receiving the operation signal.

As apparent from the above, according to the first embodiment, the induced voltage detecting circuit 8 for detecting the voltage V induced by the liquid crystal display device 5 as the therapist who is present on the current-carrying pad 3 approaches is provided, and the voltage control circuit 9 is provided. When the voltage V detected by the induced voltage detecting circuit 8 is higher than the preset upper limit voltage Vth, the voltage value of the high voltage generated by the high voltage generating circuit 2 is controlled, so that even the healer When the touch panel 6 is touched, the discharge or vibration caused by the potential difference between the therapist and the touch panel 6 can be suppressed, and as a result, the effect of attaching the liquid crystal display device 5 to which the touch panel 6 is attached can be exhibited.

Embodiment 2.

In the first embodiment, the insulating communication circuit 10 is configured to transmit and receive signals exchanged between the voltage control circuit 9 and the liquid crystal display device 5 in a state in which the voltage control circuit 9 is electrically insulated from the liquid crystal display device 5. Further, the power supply system for the liquid crystal display device 5 is not particularly described. For example, as shown in FIG. 2, an insulating transformer 20 connected to the power supply circuit 1 on the primary side and connected to the liquid crystal display device 5 on the secondary side may be mounted. The insulating transformer 20 supplies electric power to the liquid crystal display device 5 in a state in which the power supply circuit 1, the high voltage generating circuit 2, and the voltage control circuit 9 are electrically insulated from the liquid crystal display device 5.

In addition, the insulated communication circuit 10 is capable of maintaining the voltage control circuit 9 and the liquid crystal display. The device 5 can transmit and receive signals in a state of electrical insulation. For example, the constituent elements of the transmitting side of the signal can be used as a light-emitting element (for example, a light-emitting diode), and the constituent elements of the receiving side of the signal can be used as the light-receiving element. (for example, a photoelectric crystal) constitutes an insulated communication circuit 10.

Further, the reception signal may be transmitted by a communication method of a wireless communication standard such as Bluetooth (registered trademark) or Wi-Fi.

In the first and second embodiments, the induced voltage applied to the portion of the liquid crystal display device 5 of the main body device is detected, and the voltage generated from the high voltage generating circuit 2 is controlled as an example, and the same as the above description. The concept detects induced voltages in other parts of the body device (e.g., disposed near various connection terminal portions of the body device, etc.) or as a whole, and controls the voltage applied to the therapist. Further, in the first and second embodiments, the case where the voltage value of the high voltage generated by the high voltage generating circuit 2 is restored to the voltage before the reduction is described as an example in the case where the therapist is separated from the touch panel. However, it is not completely limited to "recovering the voltage before the reduction", as long as the control for lowering the voltage value is released.
