  However, the above-described conventional technology has room for improvement from the viewpoint of improving the user's experience while ensuring safety. For example, as in the prior art disclosed in Patent Document 1, just by continuing to output the same frequency and voltage for a long time, the same nerve stimulation is repeated, so that the nerve is fatigued and the sensation is attenuated.

  Further, when the frequency of the output voltage is lowered, it becomes close to the waveform of the DC voltage, so that current easily flows through the human body. Therefore, when using a low frequency as the output voltage, it is required to suppress the current flowing through the human body and ensure safety.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to provide a highly safe potential treatment that can improve the sensation and exert an excellent healing effect by the application method of the output voltage.

  According to the potential treatment device of the present invention, the waveform of the output voltage is periodically changed by controlling the inverter with the control device. Thereby, nerve fatigue is suppressed and the user's experience is improved. And, by setting the period and output pattern to change the waveform of the output voltage appropriately, calm the user's mood by the sedative action, relieve tension and stress, and exhibit an excellent relaxing effect or healing effect Can do.

  An output pattern for raising the output voltage from a predetermined start frequency to a predetermined end frequency higher than the start frequency may be periodically executed. Such an output pattern of gradually increasing the frequency of the output voltage can suppress the habituation phenomenon of the nerve and further enhance the effect of sedation.

  Further, an output pattern for increasing the voltage of the output voltage from a predetermined start voltage to a predetermined end voltage higher than the start voltage may be periodically executed. Such an output pattern of gradually increasing the voltage of the output voltage can also suppress the nerve habituation phenomenon. As a result, the user can easily experience periodic changes in the output voltage, and the healing effect is further enhanced.

  Further, the output pattern may include at least one interval at which the voltage is set to a predetermined basic voltage lower than the start voltage in the process of increasing the voltage of the output voltage. Thereby, the effect which relieves nerve fatigue further increases and a suitable bodily sensation can be maintained.

  Further, when the frequency of the output voltage is lower than a predetermined reference frequency, the time during which the positive or negative voltage in one cycle of the output voltage is applied is shorter than ½ cycle, and every ½ cycle. A non-voltage time may be provided. Thereby, the electric current which flows into a human body can be reduced and safety can be improved.

Hereinafter, a potential treatment device according to an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a potential treatment device 1 according to an embodiment of the present invention. The potential treatment device 1 performs treatment by applying an AC output voltage to the human body. As shown in FIG. 1, the potential treatment device 1 includes a power supply circuit 2, an inverter 3, a control device 4, an operation unit 5, and a transformer 6.

  The power supply circuit 2 is connected to the AC power supply 9 and converts the AC voltage of the AC power supply 9 into a stable DC voltage that can be used by the inverter 3. The power supply circuit 2 may include a filter circuit (not shown) for preventing electromagnetic interference, an overload protection circuit (not shown) that stops the operation of the power supply circuit 2 when an abnormality such as overload, overvoltage, or low voltage occurs. .

  The operation unit 5 is provided, for example, on the front surface of the casing of the potential treatment device 1 and connected to the control device 4. Then, the operation unit 5 receives an operation by the user and transmits the received command to the control device 4. That is, the user can turn on / off the power, start and end treatment, set various parameters for determining the output voltage, and select output patterns 11 to 16 (see FIGS. 2 to 7) to be described later via the operation unit 5. Etc. can be performed. The operation unit 5 may be separated from the main body. Further, the connection between the operation unit 5 and the control device 4 may be a wireless connection. Further, the operation unit 5 may be provided with a display unit (not shown) for displaying various set values, operating conditions, and the like.

  The inverter 3 is connected to the output side of the control device 4 and the power supply circuit 2. The inverter 3 receives a DC voltage supplied from the power supply circuit 2 and a command from the control device 4 and outputs a predetermined AC voltage. Note that the inverter 3 may be provided with an overcurrent protection circuit (not shown), a protection fuse, or the like for stopping output when an abnormality occurs.

  The control device 4 is connected to the power supply circuit 2 and the inverter 3. The control device 4 controls and monitors the power supply circuit 2 and the inverter 3 by executing predetermined calculations based on the input of the operation unit 5 and various set values. Specifically, the control device 4 performs output voltage waveform control, timer control, display control, overload monitoring, voltage monitoring, and the like. In particular, the control device 4 of the present embodiment is characterized in that the waveform of the output voltage is periodically changed by controlling the inverter 3. Details will be described later.

  The transformer 6 is connected to the output side of the inverter 3 and boosts the AC voltage generated by the inverter 3 to the output voltage. The output voltage is transmitted to the conductor 7 via a protection circuit, an output connector, etc. (not shown) and applied to the human body.

  FIG. 2 is an explanatory diagram showing a case where the frequency of the output voltage of the potential treatment device 1 is changed. In FIG. 2, the output voltage Vp10 is not an instantaneous voltage but a peak value (peak value).

  As shown in FIG. 2, the control device 4 (see FIG. 1) sets the frequency of the output voltage every time T2 at an arbitrary voltage Vp10 (for example, an arbitrary value selected by the user from 1400 Vp to 14000 Vp). Are automatically changed to frequency F1, frequency F2, frequency F3, and frequency F4 (output pattern 11).

Specifically, the frequency F1 (starting frequency) is first output for a predetermined time T2, then the frequency F2 is output for a predetermined time T2, and then the frequency F3 is output for a predetermined time T2, and finally The frequency F4 (end frequency) is output for a predetermined time T2.
Then, the output pattern 11 for changing the frequency of the output voltage from the frequency F1 to the frequency F4 is repeated. Note that the change in frequency is not limited to four stages.

  Here, the frequency of the output voltage of the potential treatment device 1 increases in the order of the frequency F1, the frequency F2, the frequency F3, and the frequency F4. For example, the frequency F1 is 25 Hz, the frequency F2 is 55 Hz, the frequency F3 is 85 Hz, and the frequency F4 is 115 Hz. That is, the potential treatment device 1 periodically executes the output pattern 11 that gradually increases the frequency. As described above, the output pattern 11 that gradually increases the frequency of the output voltage can suppress the nerve habituation phenomenon and improve the user's experience.

  In the present embodiment, the frequency F4 is set to the highest frequency, and then the frequency is reduced to the lowest frequency F1 at a stroke. However, the output pattern is gradually increased after the frequency is gradually increased. You may do it. Also in this case, nerve fatigue can be alleviated by increasing the frequency gently (stepwise) in the process of increasing the frequency.

  Here, for example, the time T2 for continuing the frequency F1 to the frequency F4 is 5 minutes, and the time T1 that is the period of the output pattern 11 is 20 minutes. Further, the time T2 for outputting the frequency F1 to the frequency F4 may be different in length. That is, the interval (time T2) for changing the frequency may not be equal.

  Further, the time T1, which is the cycle of the output pattern 11, may be longer than 20 minutes or shorter. For example, the cycle of the output pattern 11 may be brought close to or synchronized with a human respiratory cycle or an increase / decrease cycle of an electrical signal (alpha wave) emitted from the brain when relaxed. Specifically, the time T1 that is the cycle of the output pattern 11 may be set to 5 to 20 seconds. In the present embodiment, an operation mode in which the time T1 is 8 seconds can be executed. As a result, the sedative effect can be enhanced to calm the user's mood, and tension and stress can be relieved to exhibit an excellent relaxing effect or healing effect.

  FIG. 3 is an explanatory diagram showing a case where the voltage of the output voltage of the potential treatment device 1 is changed. Note that the voltages Vp1 to Vp4 shown in FIG. 3 are not instantaneous voltages but peak values.

  As shown in FIG. 3, the control device 4 (see FIG. 1) sets the output voltage at an arbitrary frequency F10 (for example, an arbitrary value selected by the user from 25 Hz to 115 Hz) every time T3. The voltage Vp1, the voltage Vp2, the voltage Vp3, and the voltage Vp4 are automatically changed (output pattern 12).

Specifically, the voltage Vp1 (start voltage) is output for a predetermined time T3, then the voltage Vp2 is output for a predetermined time T3, and then the voltage Vp3 is output for a predetermined time T3, and then the voltage Vp4 (end) Voltage) is output for a predetermined time T3.
Then, the output pattern 12 for changing the voltage of the output voltage from the voltage Vp1 to the voltage Vp4 is repeated. The voltage change is not limited to four stages.

  Here, the voltage of the output voltage of the potential treatment device 1 increases in the order of the voltage Vp1, the voltage Vp2, the voltage Vp3, and the voltage Vp4. For example, the voltage Vp1 is 5000 Vp, the voltage Vp2 is 8000 Vp, the voltage Vp3 is 11000 Vp, and the voltage Vp4 is 14000 Vp. That is, the potential therapy device 1 periodically executes the output pattern 12 that gradually increases the output voltage. In this way, the habituation phenomenon of the nerve can also be suppressed by the output pattern 12 that gradually increases the voltage of the output voltage.

  In the present embodiment, the voltage Vp4 is set to the highest voltage, and then the voltage is reduced to the lowest voltage Vp1 at once. However, an output pattern in which the voltage is gradually increased and then gradually decreased is adopted. You may do it. Also in this case, nerve fatigue can be alleviated by increasing the voltage gently (stepwise) in the process of increasing the voltage.

  Here, for example, the time T3 for continuing the voltage Vp1 to the voltage Vp4 is 75 seconds, and the time T1 that is the cycle of the output pattern 12 is 5 minutes. Further, the interval for changing the voltage (time T3) may not be equal. That is, the time T3 for outputting the voltage Vp1 to the voltage Vp4 may be different for each voltage.

  Further, the time T1, which is the cycle of the output pattern 12, may be longer than 5 minutes or shorter. For example, if the time T1 is set to 5 to 20 seconds, which is shorter than 5 minutes, does the cycle of the output pattern 12 approach the human respiratory cycle or the increase / decrease cycle of the electrical signal generated from the brain when the human relaxes? Or synchronize. As a result, the sedative effect can be further enhanced, and an excellent relaxing effect and healing effect can be exhibited.

  FIG. 4 is an explanatory diagram showing a case where the frequency and voltage of the output voltage of the potential treatment device 1 are changed. Note that the voltages Vp1 to Vp4 shown in FIG. 4 are not instantaneous voltages but peak values.

  As shown in FIG. 4, the control device 4 (see FIG. 1) automatically changes the output voltage to voltage Vp1, voltage Vp2, voltage Vp3, and voltage Vp4 at time T3 at time T2, and also at time T2. Every time, the frequency is automatically changed to frequency F1, frequency F2, frequency F3, and frequency F4 (output pattern 13).

  That is, the output pattern 13 is an output pattern in which the output pattern 11 shown in FIG. 2 and the output pattern 12 shown in FIG. 3 are combined. As a result, in addition to the effects of changing only the frequency and changing only the voltage, a further healing effect can be exhibited by the synergistic effect of the change in frequency and the change in voltage. Note that the steps of increasing the voltage and frequency are not limited to four stages.

  Further, by appropriately setting the time T1, the time T2, and the time T3 of the output pattern 13, a further sedative effect can be exhibited. For example, in this embodiment, the time T1 is 32 seconds, the time T2 is 8 seconds, and the time T3 is 2 seconds.

  FIG. 5 is an explanatory diagram showing a case where an interval T5 in which the frequency of the output voltage of the potential treatment device 1 is changed and the voltage is changed to the basic voltage Vp0 is included in the change. In FIG. 5, the output voltage Vp10 and the basic voltage Vp0 are not instantaneous voltages but peak values.

  As shown in FIG. 5, the control device 4 (see FIG. 1) changes the frequency to the frequency F1, the frequency F2, the frequency F3, and the frequency F4 every time T2, and sets the voltage to the basic voltage Vp0 every time T2. An interval T5 is provided (output pattern 14). That is, the control device 4 outputs the voltage as the voltage Vp10 (starting voltage) for a time T4 shorter than the time T2, and then changes the voltage to the basic voltage Vp0. That is, the time T4 is a time for applying the voltage Vp10, and the interval T5 is a time for applying a predetermined basic voltage Vp0 lower than the voltage Vp10.

  Note that the number of intervals T5 included in one cycle (time T1) is at least one time and is not limited to four times, and the interval T5 may be different every time it is output. The frequency F01 in the interval T5 takes the same value as the frequency F1 or F2, the frequency F02 is the same value as the frequency F2 or F3, the frequency F03 is the same value as the frequency F3 or F4, and the frequency F04 is the frequency F4 or frequency. Each takes the same value as F1.

  Here, the basic voltage Vp0 is a voltage lower than the voltage Vp10 that is the start voltage (for example, a voltage of 1400 Vp), and may be no voltage, that is, 0 Vp. That is, the interval T5 corresponds to a break time in which the output voltage is suppressed. In this way, by providing the interval T5 that is a break time, it is possible to refresh the nerve and maintain a suitable experience.

  In addition, by appropriately setting the time T1 and the interval T5, the rhythm of the output pattern 14 can be brought close to a human heartbeat. Thereby, a new experience is generated. In this embodiment, the time T1 is 16 seconds and the interval T5 is about 1 to 3 seconds. The time T1 is preferably 5 to 20 seconds so as to enhance the sedative effect.

  FIG. 6 is an explanatory diagram showing a case where an interval T5 in which the voltage of the output voltage of the potential treatment device 1 is changed and the voltage is changed to the basic voltage Vp0 is included in the change. In FIG. 6, the output voltage voltages Vp1 to Vp4 and the basic voltage Vp0 are not instantaneous voltages but peak values.

  As shown in FIG. 6, the control device 4 (see FIG. 1) sets the output voltage to a voltage Vp1 (starting voltage), a voltage Vp2, and a voltage Vp3 every time T3 at an arbitrary frequency F10 selected by the user. And an interval T5 for changing the voltage to the basic voltage Vp0 every time T3 (output pattern 15).

  That is, the control device 4 outputs the voltage as one of the voltages Vp1 to Vp4 for a time T4 shorter than the time T3, and then changes the voltage to the basic voltage Vp0. That is, the time T4 is a time for applying any one of the voltages Vp1 to Vp4, and the interval T5 is a time for applying a predetermined basic voltage Vp0 lower than the voltage Vp1 that is the start voltage. Note that the number of intervals T5 included in one cycle (time T1) is at least one time and is not limited to four times, and the interval T5 may be different every time it is output.

  Here, the basic voltage Vp0 is a voltage lower than the voltage Vp1 that is the start voltage. For example, when the voltage Vp1 is 5000 Vp, the basic voltage Vp0 is 1400 Vp. The basic voltage Vp0 may be no voltage, that is, 0 Vp. That is, the interval T5 corresponds to a break time in which the output voltage is suppressed. Thus, by providing the interval T5 where the voltage of the output voltage is low, it is possible to refresh the nerve and maintain a suitable experience.

  Further, by suitably setting the time T1 and the interval T5, the rhythm of the output pattern 15 can be brought close to a human heartbeat. Thereby, a new experience is generated. In this embodiment, the time T1 is 16 seconds and the interval T5 is about 1 to 3 seconds. The time T1 is preferably 5 to 20 seconds so as to enhance the sedative effect.

  FIG. 7 is an explanatory diagram showing a case where the frequency and voltage of the output voltage of the potential treatment device 1 are changed, and the change includes the interval T5 in which the voltage is set to the basic voltage Vp0. In FIG. 7, the output voltages Vp1 to Vp4 and the basic voltage Vp0 are not instantaneous voltages but peak values.

  As shown in FIG. 7, the control device 4 (see FIG. 1) changes the frequency to frequency F1, frequency F2, frequency F3, and frequency F4 at intervals of time T3. At the same time, after the voltage Vp1 as the start voltage is output for time T4, the base voltage Vp0 lower than the voltage Vp1 is output for the interval T5, and then the voltages are the voltage Vp2, the base voltage Vp0, the voltage Vp3, the base voltage Vp0, the voltage Vp4 and basic voltage Vp0 are changed (output pattern 16). The interval T5 is provided every time T3.

  That is, the output pattern 16 is an output pattern in which the output pattern 14 shown in FIG. 5 and the output pattern 15 shown in FIG. 6 are combined. As a result, in addition to the effects of changing only the frequency and changing only the voltage, a further healing effect can be exhibited by the synergistic effect of the change in frequency and the change in voltage.

  Note that the number of intervals T5 included in one cycle (time T1) is at least one time and is not limited to four times, and the interval T5 may be different every time it is output.

FIG. 8 is an explanatory diagram showing an example of the waveform of the output voltage of the potential treatment device 1. Here, the voltage V indicates an instantaneous value. When outputting a frequency lower than a predetermined reference frequency, the control device 4 (see FIG. 1) applies a positive voltage for a time T11, does not apply a voltage during the no-voltage time T12, and applies a negative voltage for a time. After applying T11, a waveform in which no voltage is applied for the no-voltage time T12 is repeated periodically.
The time T11 during which the positive and negative voltages are applied is shorter than ½ of the period time T10. Note that the time T11 during which the positive and negative voltages are applied may not be the same time.

  Here, the reference frequency serving as a reference for changing the waveform is, for example, 50 Hz. That is, for example, when the frequency of the output voltage is 25 Hz, the waveform shown in FIG. 8 is output. In this way, by outputting a waveform provided with the no-voltage time T12 at a low frequency, the current flowing through the human body can be reduced and safety can be improved.

9 (A) is the case of changing the frequency of the output voltage of the electric potential therapy apparatus 1, and FIG. 9 (B), when changing the voltage, FIG. 9 (C) were varied frequency and voltage It is explanatory drawing which shows the other example of a case. Here, the voltage V indicates an instantaneous value.

  FIG. 9A shows a change in which the frequency gradually increases with time. In the output pattern 11 (see FIG. 2), the output pattern 13 (see FIG. 4), the output pattern 14 (see FIG. 5), etc., which have already been described, the frequency is switched stepwise (stepped) at every predetermined time T2. However, the frequency may be changed gently (continuously) as shown in FIG. Even when the frequency is gradually lowered, it may be continuously changed.

  FIG. 9B shows a change in which the voltage gradually increases with time. In the output pattern 12 (refer to FIG. 3), the output pattern 13 (refer to FIG. 4), the output pattern 15 (refer to FIG. 6), and the output pattern 16 (refer to FIG. 7), the voltage is switched step by step every time T3. As shown in FIG. 9B, the voltage may be changed gently. Even when the voltage is gradually decreased, the voltage may be changed gently.

  FIG. 9C shows a change in which the frequency and voltage gradually increase with time. Even when the frequency and the voltage are changed at the same time, the frequency and the voltage may be changed gradually instead of stepwise. Further, when the frequency and voltage are lowered, they may be changed gently.

  As shown in FIGS. 9A to 9C, by continuously changing at least one of the frequency and the voltage, it is possible to suppress the nerve stimulation and the body sensation while suppressing excessive stimulation and uncomfortable feeling due to a sudden change. Can be improved. Thereby, the healing effect can be further enhanced.

  In addition, this invention is not limited to the said embodiment, In addition, a various change implementation is possible in the range which does not deviate from the summary of this invention.
