Potential therapy device

The present invention relates to an electric potential treatment apparatus that performs treatment using an electric field, and more particularly to an electric potential treatment apparatus that can apply a low frequency stimulus to a human body.

The potential treatment device applies a high potential to a human body insulated from the ground, and performs treatment using a biostimulation action by an electric field formed around the human body. In some potential treatment devices, an electric field is formed around the human body due to a potential difference generated by applying an alternating voltage to the human body and the counter electrode. In a potential treatment device having an alternating current component, the frequency is Many have commercial power supply frequencies (50 Hz / 60 Hz) and high frequency components. In general, a transformer is used to boost a commercial power source to generate an alternating high voltage, which is applied to an electrode to give a high potential to a human body insulated from the ground (for example, , See Patent Document 1).

By the way, the low rhythm and music below the frequency (1 to 1.5 Hz) such as the normal heart cycle of the human body (60 to 90 beats / minute * varies depending on gender, age and individual differences), the human body is parasympathetic. It is known to be in a relaxed state (see, for example, Non-Patent Document 1).

Therefore, it is conceivable to generate a low-frequency AC high voltage by supplying a low-frequency AC low voltage to the transformer in advance in an AC high-voltage potential treatment device.

Takenaka Mikako and three others, “Study on physiological responses by listening to rhythm with tempo based on heart rate”, [online], March 2005, Clinical Education Psychology, [November 16, 2011 search ] Internet <URL: http://ci.nii.ac.jp/naid/110004500192>

However, the conventional potential treatment apparatus boosts the commercial power supply 100V (50/60 Hz) to several hundred volts or several thousand volts using a transformer, but such an existing transformer has a low frequency of 20 Hz or less. However, if an AC low voltage is supplied to generate an AC high voltage at a low frequency, the circuit becomes complicated and disadvantageous in terms of cost and reliability, which is substantially difficult.

Therefore, the present invention uses an existing transformer, and with a simple circuit configuration, can provide a low-frequency stimulation similar to that generated when a low-frequency AC low voltage is generated to the human body, and can be expected to have a relaxing effect. The object is to provide a therapeutic device.

In order to solve the above-mentioned problem, the invention of claim 1 is connected to a commercial power source, a first electrode facing the human body in a non-contact manner, a second electrode facing the first electrode and contacting the human body, and In the circuit between the first transformer for applying an AC high voltage to the first electrode, the second transformer connected to the commercial power source and applying the AC high voltage to the second electrode, and the commercial power source and the first electrode, And / or a frequency converter that is provided in a circuit between the commercial power source and the second electrode and converts the frequency of the commercial power source, and the frequency of the AC high voltage applied to the first electrode, A potential therapy apparatus characterized in that a difference is provided between the frequency of the alternating high voltage applied to the second electrode.

According to the present invention, a difference is generated in the frequency of the alternating high voltage applied to the first electrode and the second electrode, respectively, which can be given to the human body (the subject) as a low frequency electric field strength.

According to a second aspect of the present invention, in the potential treatment device according to the first aspect, the difference between the frequency of the AC high voltage applied to the first electrode and the frequency of the AC high voltage applied to the second electrode is calculated. The frequency is set to be equal to or lower than the normal heartbeat frequency of the human body.

According to the present invention, the difference in the frequency of the alternating high voltage applied to the two electrodes is beaten and given to the human body as a frequency stimulus close to the human heartbeat.

According to a third aspect of the present invention, in the electric potential treatment device according to the first or second aspect, most of the treatment time is set to a frequency lower than that of the normal heartbeat, and the vicinity of the end of the treatment time is set to be higher than the previous frequency Is also set high.

According to the present invention, a beat with a frequency lower than that of the heartbeat is provided for most of the treatment time, and a beat with a higher frequency near the end time is given to the human body as a stimulus.

According to the first aspect of the present invention, a plurality of AC high-voltage electric fields having different frequencies can be used without complicating the electric circuit, using the existing transformer, and being not disadvantageous in terms of cost and reliability. Can be formed. AC high-voltage electric fields having different frequencies generate “beats”, and “beats” can realize low-frequency stimulation. Conventionally, a voltage detector that drives a lamp, a buzzer, etc. by detecting a weak current by contacting or approaching the human body of the patient to be treated with a high potential has been used. In the potential treatment apparatus of the present invention, the person to be treated has a voltage detector, and the low frequency by bringing the voltage detector closer to the first electrode. The intensity of the lamp light and buzzer sound are generated, and it is possible to clearly recognize that the patient is being treated.

According to the second aspect of the present invention, it is possible to give the human body a “beat” with a low frequency close to the normal heartbeat of the human body, and expect a parasympathetic nerve-dominated relaxation effect in addition to the therapeutic effect as a potential treatment device. be able to.

According to the third aspect of the present invention, a low frequency stimulation of the normal heartbeat is given to the human body during most of the treatment, and a high frequency stimulation of the heartbeat is given to the human body during the latter half of the treatment. At the end of treatment, a slightly higher frequency stimulation with sympathetic nerve superiority can bring the human body into an active state and finish the treatment.

It is a schematic circuit diagram which shows the electric potential treatment apparatus which concerns on Embodiment 1 of this invention. It is the schematic diagram which represented typically the electrode and human body for forming an electric field.

The present invention will be described below based on the illustrated embodiments.
(Embodiment 1)
The potential treatment apparatus 1 includes a chair B on which a patient is seated, a first electrode T1 positioned above the chair B and facing the head of the patient to be seated in a non-contact manner, It has the 2nd electrode T2 which is the front of the chair B, and in which the foot | leg of a to-be-treated patient is mounted, and the voltage generation unit 20 which supplies the alternating current high voltage applied to these electrodes T1 and T2.

The chair B is mainly composed of a seat portion 11, a backrest 12, and left and right sidewalls 13, and an operation panel for performing operations such as turning on and off the power source on the upper end surface of one of the sidewalls 13. 14 is disposed. In addition, the chair B includes a head electrode case 15 in which a surface layer material is covered with an insulating material and the first electrode T1 is built in, and a footrest (electricity table) in which a surface layer material is covered with an insulating material and the second electrode T2 is built in. ) 16 is provided.

The voltage generation unit 20 includes two transformers 21 and 22 each connected to a commercial power source A (for example, 100 V: 50 Hz, the same applies hereinafter). The first transformer 21 has a predetermined AC high voltage on the first electrode T1. A voltage (for example, 9000V) is applied, and the second transformer 22 applies a predetermined AC high voltage (for example, 9000V) to the second electrode T2.

The two transformers 21 and 22 have the same structure, but a frequency converter (FC) 23 is connected to the primary side of the second transformer 22.

That is, the primary winding 21a of the first transformer 21 is connected to the commercial power source A via the switches SW1 and SW2, and one end of the secondary winding 21b is connected to the first via the current limiting element (safety resistor) 21c. The electrode T1 is connected to the ground G at the other end.

On the other hand, the primary winding 22a of the second transformer 22 is connected to the commercial power source A via the switches SW1 and SW2 and the frequency converter 23, and one end of the secondary winding 22b is a current limiting element (safety resistor) 22c. The other end is connected to the ground G through the second electrode T2. The reason why the current limiting elements 21c and 22c are connected to the secondary windings 21b and 22b of the transformers 21 and 22 is to prevent a large current from flowing.

The switches SW1 and SW2 connected to the transformers 21 and 22 are switched ON and OFF by a power button disposed on the operation panel 14, and when the switches SW1 and SW2 are turned ON, the transformers 21, In both cases, the secondary windings 21b and 22b are stepped up to 9000 V and an AC high voltage 9000 V is applied to the first electrode T1 and the second electrode T2.

Further, since the commercial power source A is directly input to the primary winding 21a side of the first transformer 21, an AC high voltage of the same frequency (50 Hz) as that of the commercial power source A is output to the secondary winding 21b. . On the other hand, since the commercial power source A is connected to the primary winding 22a side of the second transformer 22 via the frequency converter 23, the frequency (50 Hz) of the commercial power source A is set to a predetermined frequency F1 (for example, AC high voltage converted to 51 Hz) is output.

"Usage and Action"
Next, the usage method and operation of the potential treatment device 1 having such a configuration will be described.

First, the patient is seated on the chair B, and the foot of the human body M is placed on the footrest 16. In this state, the first electrode T1 of the head electrode case 15 is positioned in a state of being separated above the head of the human body M, and the second electrode T2 of the footrest 16 is disposed on the foot of the human body M via an insulator. Contact.

Next, when the power button on the operation panel 14 is operated to turn on the switches SW1 and SW2, the commercial power A100V: 50 Hz is supplied to the voltage generation unit 20.

And since the commercial power supply A100V: 50 Hz is inputted as it is to the first transformer 21, an AC high voltage of 9000 V: 50 Hz is generated in the secondary winding 21 b.

On the other hand, the frequency is converted from F2 = 50 Hz to 51 Hz by the frequency converter 23 connected to the primary winding 22a side of the second transformer 22, and is input from the secondary winding 22b to 9000 V: F2. = 51 Hz AC high voltage is generated.

As a result, an alternating high voltage of 9000 V: 50 Hz is applied to the first electrode T1 on the head side, and an alternating high voltage of 9000 V: 51 Hz is applied to the second electrode T2 on the foot side. A potential difference is generated between T1 and T2, and a high potential is applied to the patient to be treated, and the potential treatment is performed by utilizing the biostimulation action by the electric field formed around the human body M.

A slight difference of 1 Hz occurs in the frequency of the AC high voltage applied to the electrodes T1 and T2, which causes the AC electric field to be strong and weak, which can be felt by the patient as a beat. M is given a low-frequency stimulus.

The frequency difference 1 Hz of the alternating high voltage applied to the two electrodes T1 and T2 can be changed by adjusting the frequency converter 23, for example, the frequency supplied to the second transformer 22 If the frequency is adjusted to be converted to 51 Hz, the difference between the frequencies of the alternating high voltage applied to the two electrodes T1 and T2 is 1 Hz, and the subject can receive a low frequency stimulus of 1 Hz.

The difference in the frequency of the alternating high voltage applied to the two electrodes T1 and T2 is substantially the same as the low frequency below the frequency (1 to 1.8 Hz) of the normal heartbeat period (60 to 90 beats / minute) of the human body, or By making the approximation, it is possible to expect a relaxation effect with parasympathetic nerve dominance.

As described above, since the frequency converter 23 is simply connected to the existing transformer 22 in order to give a low frequency stimulus to the patient, the cost is increased without using a complicated electric circuit configuration. In addition, a reliable circuit design can be achieved.

In addition, conventionally, a person other than the person to be treated has a voltage detector and is brought into contact with or close to the body of the person to be treated at a high potential, and a weak current is detected to drive the lamp, buzzer, etc. of the voltage detector. However, in the electric potential treatment apparatus of the present invention, the subject himself / herself has a voltage detector, and the strength of the lamp light and buzzer sound is reduced by the low frequency (beat) by bringing the voltage detector closer to the first electrode. And the person being treated can clearly recognize that it is being treated.

In the first embodiment, the frequency converter 23 is disposed on the primary winding 22a side of the second transformer 22. However, the potential treatment apparatus 1 of the present invention is not limited to this. Instead of the second transformer 22, the primary winding 21 a side of the first transformer 21 may be used. Furthermore, you may make it provide in both the 1st transformer 21 and the 2nd transformer 22. FIG. In short, it may be set so that a slight difference is generated in the frequency of the AC high voltage applied to the first electrode T1 and the second electrode T2.
(Embodiment 2)
Next, a second embodiment of the potential treatment device that can vary the frequency of stimulation close to the human body M during treatment will be described. The second embodiment is different from the first embodiment in that the frequency of the AC high voltage applied during the treatment time is changed. Therefore, since each component is the same as that in the first embodiment, the illustration is omitted, and description will be given with reference to FIGS. 1 and 2 used in the first embodiment.

For example, if the treatment time of the potential treatment device 10 is 60 minutes, the remaining 10 minutes so that a beat with a frequency slightly lower than the normal heartbeat (for example, 0.4 Hz) occurs for 50 minutes from the start (most treatment). The frequency converter 23 is controlled so that a beat with a higher heartbeat frequency (for example, 1.8 Hz) occurs during the minute (second half of the treatment).

Specifically, the frequency of the AC power input to the second transformer 22 is set so that the frequency F2 = 50.4 Hz for 50 minutes after the start of treatment (the power button of the potential treatment device 1 is turned on), and thereafter. In the latter half 10 minutes, the frequency converter 23 is controlled so that the frequency F2 = 51.8 Hz.

Thereby, an AC high voltage having a frequency F2 = 50.4 Hz slightly lower than the normal heartbeat is applied to the second electrode T2 for 50 minutes from the start of treatment, and a higher frequency F2 = 51. An AC high voltage of 8 Hz is applied.

Thus, the electric field formed by the AC high voltage of the first electrode T1 and the AC high voltage of the second electrode T2 generates a 0.4 Hz beat slightly lower than the normal heartbeat frequency for 50 minutes from the start of treatment. For the remaining 10 minutes, a beat with a frequency of 1.8 Hz, which is a higher heart rate, usually occurs.

Since the subject receives stimulation at a frequency lower than the normal heartbeat (0.4 Hz) for 50 minutes after the start of treatment, the subject is in a relaxed state with parasympathetic dominance, and the normal heartbeat frequency (1. 8Hz), the sympathetic nerve is dominant and the reduction of the arousal level is prevented, and the treatment can be finished in an active state.

As described above, according to the potential treatment device 1 of the second embodiment, the low-frequency stimulation that is slightly lower than the normal heartbeat frequency during most of the treatment, and the high-frequency heartbeat stimulation in the latter half of the treatment or near the end. Since the human body M is given a relaxing effect, the treatment can be ended with the human body M in an active state by a slightly higher frequency stimulation with sympathetic nerve superiority at the end of the treatment while giving a relaxing effect.

In this way, by controlling the frequency converter 23 and changing the frequency of the AC high voltage applied to the two electrodes over time, the frequency difference can be made before and after the cycle centered on the heart rate. Therefore, it is possible to select a sympathetic nerve / parasympathetic nerve dominant state, and it is possible to appropriately treat each subject.

In the second embodiment, it has been described that the treatment time is 60 minutes. However, the treatment time is not limited to this, and the treatment is performed by appropriately changing the short time or the long time according to the treatment status of the human body M. It is also possible to do.

Although the embodiments of the present invention have been described above, the specific configuration is not limited to the above-described embodiments, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the above embodiment, it has been described that the voltage boosted by the first transformer 21 and the second transformer 22 is boosted to the same voltage value. However, the present invention is not limited to this, and the first electrode T1 and the first transformer Different voltage values may be applied to the two electrodes T2.

Further, the difference in the frequency of the AC high voltage applied to the first electrode T1 and the second electrode T2 is set to 1 Hz in the first embodiment, and 0.4 Hz and 1.8 Hz in the second embodiment. Although the generation of the beat at the frequency of 1 Hz, 0, 4 Hz, or 01.8 Hz has been described, the potential treatment device 1 of the present invention is not limited to this, and any frequency may be used as long as the person to be treated can sense the beat.

Furthermore, although it has been described that the second electrode T2 is built in the footrest 16, for example, the second electrode T2 may be built in the seat portion 11.
