Description
Technical Field
The present invention relates to a potential therapeutic apparatus for therapy using an electric field, and more particularly, to a potential therapeutic apparatus capable of applying low frequency stimulation to a human body.
Background
The electric potential therapy apparatus is an apparatus for applying a high electric potential to a human body insulated from the ground and performing therapy by utilizing a biostimulation effect by an electric field formed around the human body. In a potential treatment apparatus having an alternating current component, the frequency of the potential treatment apparatus often has a commercial power frequency (50Hz/60Hz) or a high-frequency component. It is known that a commercial power supply is boosted by a transformer (トランス; transformer) to generate an ac high voltage, and the ac high voltage is applied to an electrode to apply a high potential to a human body insulated from the ground (see, for example, patent document 1).
It is also known that a human body is in a relaxed state with parasympathetic activity with a low frequency rhythm or music having a frequency (1 to 1.5Hz) equal to or less than a normal human body heart cycle (60 to 90 beats/minute depending on gender, age, and individual differences) (for example, see non-japanese patent document 1).
Therefore, in the ac high-voltage potential therapy apparatus, it is considered that a low-frequency ac low voltage is supplied to a transformer in advance to generate a low-frequency ac high voltage.

Disclosure of Invention
Technical problem to be solved
However, although the conventional electric potential therapy apparatus boosts the voltage of the commercial power supply 100V (50/60Hz) to several hundred volts or several kilovolts using a transformer (トランス; transformer), if a low-frequency ac low voltage of 20Hz or less is supplied to such a conventional transformer to generate a low-frequency ac high voltage, the circuit becomes complicated, and is disadvantageous in terms of cost and reliability, which is actually difficult.
Accordingly, an object of the present invention is to provide a potential therapeutic apparatus which can apply a low-frequency stimulus similar to that generated when a low-frequency ac low voltage is generated to a human body with a simple circuit configuration using an existing transformer, and can expect a relaxation effect.
(II) technical scheme
In order to solve the above-mentioned technical problem, the invention according to claim 1 relates to a potential therapeutic apparatus, comprising: a first electrode arranged to face a human body in a non-contact manner; a second electrode opposite to the first electrode and contacting the human body; a first transformer connected to a commercial power supply and applying an ac high voltage to the first electrode; a second transformer connected to the commercial power supply and applying an ac high voltage to the second electrode; a frequency converter provided in a circuit between the commercial power source and the first electrode and/or a circuit between the commercial power source and the second electrode, for converting a frequency of the commercial power source; a difference is provided 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.
According to the present invention, the difference between the frequencies of the ac high voltages applied to the first electrode and the second electrode can be converted into a beat frequency, and the beat frequency can be applied to the human body (the subject) as a low-frequency electric field intensity.
The invention according to claim 2 is the electric potential treatment apparatus according to claim 1, wherein a difference between a frequency of the ac high voltage applied to the first electrode and a frequency of the ac high voltage applied to the second electrode is set to be equal to or lower than a normal human heart rate.
According to the present invention, the difference between the frequencies of the ac high voltages applied to the two electrodes becomes a beat frequency, and is applied to the human body as a frequency stimulus close to the heartbeat of the human body.
The invention according to claim 3 is the electric potential treatment apparatus according to claim 1 or 2, wherein most of the treatment time is set to a frequency lower than the normal heartbeat, and the vicinity of the end of the treatment time is set to a frequency higher than the frequency before the end of the treatment time.
According to the invention, a beat frequency lower in frequency than the heartbeat or a beat frequency higher in frequency in the vicinity of the end is applied to the human body as a stimulus for most of the treatment time.
(III) advantageous effects
According to the invention described in claim 1, by using the existing transformer, it is possible to form a plurality of ac high-voltage electric fields having different frequencies without complicating the electric circuit and without causing disadvantages in terms of cost and reliability. The alternating high-voltage electric field with different frequencies generates beat frequency which can realize low-frequency stimulation. In addition, conventionally, an electroscope has been used which is brought into contact with or close to a human body of a person to be treated having a high potential to detect a weak current and thereby drive a lamp, a buzzer, or the like, and is gripped by a person other than the person to be treated to use the electroscope.
According to the invention described in claim 2, a "beat frequency" having a low frequency close to the normal heartbeat of the human body can be applied to the human body, and a relaxation effect of activating parasympathetic nerves can be expected in addition to a therapeutic effect as a potential therapeutic apparatus.
According to the invention described in claim 3, since the low-frequency stimulation of the normal heartbeat is applied to the human body in most of the treatments and the frequency stimulation higher than the heartbeat is applied to the human body in the latter half of the treatments, the relaxation effect can be given to most of the treatments, and at the same time, the human body can be put into an active state by the slightly higher frequency stimulation that activates the sympathetic nerves at the end of the treatments, and the treatments can be ended.

Detailed Description
The present invention will be described below based on the illustrated embodiments.
(embodiment mode 1)
The electric potential therapy apparatus 1 comprises a chair B on which a person to be treated sits, a first electrode T1, a second electrode T2, and a voltage generating unit 20, wherein the first electrode T1 is positioned above the chair B and faces the head of the seated person to be treated in a non-contact manner, and the second electrode T2 is positioned in front of the chair B and supports the feet of the seated person to be treated; the voltage generating unit 20 supplies an ac high voltage applied to the electrodes T1 and T2.
The chair B is mainly composed of a seat 11, a backrest 12, and left and right side walls 13, and an operation panel 14 for performing operations such as turning ON and OFF of a power source is disposed ON an upper end surface of one side wall 13. Further, the chair B is provided with a head electrode case 15 in which a skin material is covered with an insulator and the first electrode T1 is built therein, and a pedal (energizing unit) 16 in which a skin material is covered with an insulator and the second electrode T2 is built therein.
The voltage generating unit 20 includes two transformers 21 and 22 connected to a commercial power supply a (e.g., 100V:50Hz, the same applies hereinafter), respectively, and the first transformer 21 applies a predetermined ac high voltage (e.g., 9000V) to the first electrode T1, and the second transformer 22 applies a predetermined ac high voltage (e.g., 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 supply a via switches SW1 and SW2, and one end of the secondary winding 21b is connected to the first electrode T1 via a current limiting element (safety resistor) 21c while the other end is connected to the ground G.
On the other hand, the primary winding 22a of the second transformer 22 is connected to the commercial power supply a via switches SW1 and SW2 and the frequency converter 23, and one end of the secondary winding 22b is connected to the second electrode T2 via a current limiting element (safety resistor) 22c while the other end is connected to the ground G. The current limiting elements 21c and 22c are connected to the secondary windings 21b and 22b of the transformers 21 and 22 to prevent a large current from flowing therethrough.
The switches SW1 and SW2 connected to the transformers 21 and 22 are switched ON and OFF by the power button disposed ON the operation panel 14, and if the switches SW1 and SW2 are turned ON, the voltages ON the secondary windings 21b and 22b of the transformers 21 and 22 are both increased to 9000V, and 9000V ac high voltage is applied to the first electrode T1 and the second electrode T2.
Further, since the commercial power supply a is directly input to the primary winding 21a side of the first transformer 21, an ac high voltage having the same frequency (50Hz) as the commercial power supply a is output to the secondary winding 21 b. On the other hand, the primary winding 22a side of the second transformer 22 is connected to the commercial power supply a through the frequency converter 23, and therefore outputs an ac high voltage that converts the frequency (50Hz) of the commercial power supply a to a predetermined frequency F1 (e.g., 51 Hz).
(method of use and action)
Next, a method of using the electric potential treatment apparatus 1 having such a structure and an operation thereof will be described.
First, the person to be treated sits on the chair B, and the feet of the human body M are placed on the pedals 16. In this state, the first electrode T1 of the head electrode cartridge 15 is located above the head of the human body M in a separated state, and the second electrode T2 of the foot plate 16 is in contact with the foot of the human body M through an insulator.
When the power button of the operation panel 14 is operated to turn on the switches SW1 and SW2, the commercial power source a100V:50Hz power is supplied to the voltage generating unit 20.
Then, since commercial power supply a100V:50Hz is directly input to first transformer 21, an ac high voltage of 9000V:50Hz is generated in secondary winding 21b thereof.
On the other hand, the frequency is converted from F2 to 50Hz to 51Hz by the frequency converter 23 connected to the primary winding 22a side of the second transformer 22, and the converted frequency is input to the second transformer 22, so that a 9000V, F2 to 51Hz ac high voltage is generated in the secondary winding 22 b.
Thus, an alternating current high voltage of 9000V 50Hz is applied to the first electrode T1 on the head side, an alternating current high voltage of 9000V 51Hz is applied to the second electrode T2 on the foot side, a potential difference is generated between the two electrodes T1 and T2, an electric field is formed around the human body M by applying a high potential to the person to be treated, and potential treatment is performed by a biostimulation effect caused by the electric field.
Further, a slight difference of 1Hz is generated in the frequency of the ac high voltage applied to each of the electrodes T1 and T2, which causes the ac electric field to be strong or weak, and causes the subject to feel as a beat frequency, so that a stimulus of a low frequency is applied to the human body M.
This can be achieved by varying the difference of the frequencies of the ac high voltages applied to the two electrodes T1, T2 by adjusting the frequency converter 23 described above, for example, if the adjustment is made so that the frequency supplied to the second transformer 22 is converted to 51Hz, the difference of the frequencies of the ac high voltages applied to the two electrodes T1, T2 is 1Hz, and the person to be treated can be stimulated by a low frequency of 1 Hz.
Then, by making the difference in the frequencies of the ac high voltages applied to the two electrodes T1 and T2 substantially the same as or similar to a low frequency equal to or lower than the frequency (1 to 1.8Hz) of the normal human heart cycle (60 to 90 beats/minute), a relaxation effect of parasympathetic activity can be expected.
As described above, since the frequency converter 23 is connected only to the existing transformer 22 in order to apply stimulation of a low frequency to the person to be treated, a reliable circuit design can be performed without increasing the cost and the complexity of the electric circuit configuration.
In addition, conventionally, an electroscope is held by a person other than the person to be treated, and the person is brought into contact with or close to the human body of the person to be treated having a high potential, and a weak current is detected to drive a lamp, a buzzer, or the like of the electroscope.
In embodiment 1, the case where the frequency converter 23 is disposed on the primary winding 22a side of the second transformer 22 has been described, but the electric potential treatment apparatus 1 of the present invention is not limited to this, and may be disposed on the primary winding 21a side of the first transformer 21 instead of the second transformer 22. Further, the first transformer 21 and the second transformer 22 may be provided at the same time. In short, it is sufficient to set a slight difference in the frequency of the ac high voltage applied to the first electrode T1 and the second electrode T2.
(embodiment mode 2)
Next, embodiment 2 of the electric potential therapy apparatus in which the frequency of stimulation close to the human body M can be changed during therapy will be described. Embodiment 2 differs from embodiment 1 in that the frequency of the applied ac high voltage is changed during the treatment time. Therefore, the respective constituent elements are the same as those of embodiment 1, and therefore, the illustration is omitted, and the description is given by using fig. 1 and 2 used in embodiment 1.
For example, if the treatment time of the potential treatment device 10 is set to 60 minutes, the frequency converter 23 is controlled so that the first 50 minutes (most of the treatment) therein produces a beat frequency of a slightly lower frequency (for example, 0.4Hz) than the usual heartbeat and the remaining 10 minutes (the latter half of the treatment) produces a beat frequency of a higher frequency (for example, 1.8Hz) than the heartbeat.
Specifically, the frequency converter 23 is controlled so that the frequency of the ac power input to the second transformer 22 becomes F2 to 50.4Hz for 50 minutes from the start of treatment (the power button of the electric potential treatment apparatus 1 is turned ON), and becomes F2 to 51.8Hz for the second half 10 minutes thereafter.
Thus, an ac high voltage having a frequency F2 of 50.4Hz, which is slightly lower than the normal heart beat, is applied to the second electrode T2 from 50 minutes after the start of the treatment, and an ac high voltage having a frequency F2 of 51.8Hz is applied to the second electrode T2 from 10 minutes before the end to the end.
Then, the beat frequency of 0.4Hz, which is slightly lower than the normal heartbeat, is generated 50 minutes from the start of the treatment by the electric field formed by the AC high voltage of the first electrode T1 and the AC high voltage of the second electrode T2, and the beat frequency of 1.8Hz, which is higher than the normal heartbeat, is generated for the remaining 10 minutes.
Therefore, the subject receives a stimulation with a frequency (0.4Hz) lower than the normal heartbeat 50 minutes after the start of the treatment, and thus a relaxed state in which the parasympathetic nerves are active is formed, and receives a stimulation with a frequency (1.8Hz) higher than the normal heartbeat 10 minutes before the end of the treatment, and thus a state in which the sympathetic nerves are active is formed, the arousal level is prevented from being lowered, and the treatment can be ended in an active state.
As described above, according to the electric potential treatment apparatus 1 of embodiment 2, since the low-frequency stimulation slightly lower than the normal heart rate is applied to the human body M in most of the treatment, and the high-frequency stimulation higher than the heart rate is applied to the human body M in the second half or near the end of the treatment, the relaxation effect can be given, and the treatment can be ended by activating the human body M with a slightly higher frequency stimulation that activates the sympathetic nerves at the end of the treatment.
By controlling the frequency converter 23 in this way, the frequency of the ac high voltage applied to the two electrodes is changed with time, so that the frequency difference can be set before and after a cycle centered on the heart rate, and a state in which sympathetic/parasympathetic nerves are active can be selected, thereby enabling appropriate treatment to be performed on each subject.
In embodiment 2, the treatment time is described as 60 minutes, but the present invention is not limited to this, and treatment may be performed in a short time or a long time as appropriate depending on the treatment state of the human body M.
While the embodiments of the present invention have been described above, the specific configuration is not limited to the above embodiments, and design changes and the like without departing from the scope of the present invention are also included in the present invention. For example, in the above-described embodiment, the embodiment has been described in which the voltages boosted in the first transformer 21 and the second transformer 22 are boosted to the same voltage values, but the present invention is not limited thereto, and different voltage values may be applied to the first electrode T1 and the second electrode T2.
Further, although the description has been made on the case where the difference between the frequencies of the ac high voltages applied to the first electrode T1 and the second electrode T2 is 1Hz in embodiment 1 and 0.4Hz and 1.8Hz in embodiment 2, and beats of 1Hz, 0.4Hz, or 01.8Hz are generated, the potential treatment device 1 of the present invention is not limited to this, and may be any frequency as long as the subject can feel beats of a low frequency.
Further, although the second electrode T2 is incorporated in the pedal 16, the second electrode T2 may be incorporated in the seat 11, for example.
