Description

The present invention relates to an alternating-current potential treatment device, and in particular, the present invention relates to an alternating-current potential treatment that can suppress fluctuations in the crest value ratio between the positive voltage and negative voltage of a living body applied alternating current due to the location of the conductive mat and the variation in usage pattern. Related to the vessel.

As a conventional AC potential treatment device, for example, Patent No. 260957 previously proposed by the applicant of the present application.
As in Japanese Patent No. 4 (Patent Document 1), the positive voltage bleeder circuit provided at both ends of the high-voltage secondary coil of the AC step-up transformer causes the peak value ratio between the positive voltage and negative voltage of the living body applied AC to be about 1: 3. By applying an alternating potential to the living body at a rate equal to the ideal ratio of positive and negative ions in a healthy human body, the potential treatment effect is effective and immediate, and a biological rejection reaction occurs. An AC potential treatment device that prevents the above is well known.

This Patent Document 1 discloses a high-voltage end P1 and a ground end of a high-voltage secondary coil L2 in a step-up transformer T in which a primary coil L1 is connected to a commercial power supply AC as shown in paragraph 0009 and a gazette of the present application and FIG. A series circuit of a resistor R2 and a diode D2 toward the ground terminal is connected in series with a parallel circuit of a diode D1 toward the high-voltage end and a resistor R1 between the P2 and the P2. A high-voltage alternating current with a peak value ratio of positive voltage to negative voltage of about 1: 3 is obtained from the part b1, and this high-voltage alternating current is applied to the conductive mat m through the protective output b2 through the protective resistor R0 of about 10 MΩ. It is an AC potential treatment device that supplies power as AC.

However, in this document 1, as shown in the above paragraph, the publication drawing, and FIG. 3 attached to the present application, 1 MΩ between the ground potential line E of the transformer primary coil L1 and the ground terminal P1 of the secondary coil L2.
The grounding terminal P2 is held at the ground potential by connecting a protective resistor R of a certain degree.

Further, paragraph 0010 of this document 1 states that “when a diseased part such as a patient's waist is placed on a conductive mat m laid on a floor of a house with an insulating sheet and insulated from the ground, a positive voltage and a negative voltage are expressed. However, such an AC potential treatment device is not limited to Patent Document 1 and is disclosed in, for example, Japanese Patent Application Laid-Open No. S58-58. 146361
Conventional examples such as Japanese Patent No. 2 (Patent Document 2) and Japanese Patent No. 4217814 (Patent Document 3)
A high-voltage alternating current was supplied as a biologically applied alternating current to the conductive mat m with an insulating coating through a protective resistance of about 10 MΩ (megohm).

In the conventional conductive mat power feeding means as described above, the resistance to ground (resistance) of the protection output terminal b2 is obtained by adding the value of the protective resistance R0 of about 10 MΩ to the value of the resistance R2 of about 12 MΩ in FIG. The resistance value is as large as about 22 MΩ, and the larger the value of each of these resistances, the higher the ratio of the crest value ratio between the positive voltage and the negative voltage of the AC applied to the living body due to the location of the conductive mat and the change in usage pattern. This creates an inherently significant problem of increased fluctuations.

However, the common AC potential treatment devices currently used, including the AC potential treatment devices of Patent Documents 1 to 3 described above, have a focus on solving the peak value ratio and product development intentions, starting with the above problems. According to the dielectric constant of the insulation coating existing between the conductive mat m and the affected part, the high-voltage AC voltage that still passes through the protective resistor R0, which is different from the voltage dividing resistor, seems to have been absent from the beginning.
It is applied to the living body through a capacitance corresponding to the variation of the usage pattern.

The capacitance varies greatly depending on variations in the use form of the conductive mat, such as the location of the conductive mat m, the manner in which the conductive mat insulating coating is closely attached to the living body affected part, and the manner of use, for example, a two-story Japanese-style room in a wooden house. When one arm is placed on the insulation coating of a rectangular conductive mat of about 30 × 40 cm placed on an insulating bed, the capacitance between the conductive mat and the affected area or the ground includes the floating capacity. About 220 pF (picofarad), the impedance at 70 Hz is about 10 MΩ.

On the other hand, when the body is laid on the entire surface of the conductive mat under the same usage conditions as described above, the capacitance between the insulating coated conductive mat and the living body or the ground is approximately 5 including the floating capacity. The impedance at 70 Hz is about 2M.
It drops to about 1/5, about Ω.

Specifically, the output voltage of the secondary coil L2 in FIG. 3 is set to a peak value of 14 KV (kilovolts), the resistor R1 in parallel with the diode D1 is set to 18 MΩ, the other resistor R2 is set to 12 MΩ, and the conductive mat m is removed. As a result of measuring the living body applied AC voltage e between the protected output terminal b2 in the unloaded state and the ground potential line E with an oscilloscope using a high-voltage probe having a ground impedance of about 100 MΩ, The negative voltage was 12.7 KV, the positive voltage was 5.46 KV, and the peak value ratio between the positive voltage and the negative voltage was 1: 2.33.

Next, the conductive mat m is connected to the protection output terminal b2 as shown in FIG.
The living body applied AC voltage e between the protection output terminal b2 and the ground potential line E is set to a high voltage as described above in a use state where the living body affected part is applied through the protective resistance R0 of about Ω and the insulating coating of the conductive mat m. Measurement was performed with an oscilloscope using a probe.

Since the impedance of the conductive mat m having the living body in close contact with the entire surface is about 2 MΩ as described above, the negative voltage of the protective output b2 is 14 × 1/6 = 2.33 KV. The positive voltage is 0.61 K.
V, and the peak value ratio between the positive voltage and the negative voltage is 0.61: 2.33 = 1: 3.82, while the impedance of the conductive mat m with one arm is about 10 MΩ as described above. ,
The negative voltage of the protection output terminal b2 is 14 × 1/2 = 7.0 KV. The positive voltage is 2.14 KV, and the peak value ratio between the positive voltage and the negative voltage is 2.14: 7.0 = 1: It was 3.27.

As a result, the variation difference of the crest value ratio between the positive voltage and the negative voltage of the living body applied alternating current due to the variation of the arrangement place of the conductive mat and the usage pattern is 3.82-3.27 = 0.55, and each wave Since an unstable factor of 15.5% is fluctuated with respect to the average value of the high value ratio of 3.55, there is a fundamental and serious problem that it may not be used as an AC potential treatment device.

The cause of the above problem is that the positive voltage difference between the conductive mat with one arm placed and the conductive mat with the affected part in close contact with the entire surface is 2.14−0.61 = 1.53 KV. However, the positive voltage difference of the interconnecting part b1 is almost halved by the voltage drop of the protective resistor R0.
Since it becomes 6 KV, the voltage drop due to the increase of the positive shunt current flowing through the resistor R2 becomes very small, and it can be assumed that the increase in the positive voltage of the conductive mat cannot be suppressed much.

That is, when the AC positive voltage at the protection output terminal b2 in FIG. 3 decreases due to the change in the arrangement location and usage of the conductive mat m, the voltage drop between the resistor R1 and the protection resistor R0 increases according to the decrease. The voltage of the interconnection b1 does not change so much, and when the AC positive voltage at the protection output terminal b2 rises, the voltage drop of the resistor R1 and the protection resistor R0 decreases according to the rise, The voltage of the connection part b1 can be estimated as the cause because it does not change so much.

In addition to these Patent Documents 1 to 3, JP-A-2006-239032 (Patent Document 4)
An AC potential treatment device having a high voltage voltage dividing circuit using an intermediate tap provided in the high voltage secondary coil of the AC voltage step-up transformer as shown in FIG.

This conventional example prevents leakage occurring between the intermediate tap and other electrical components or / and between the intermediate tap and the high-voltage secondary coil, or the occurrence of a layer short-circuit. The secondary coil is divided into the ground side and the high voltage side with the tap as a boundary, and as the bobbin of the step-up transformer, a total of three bobbins are required in addition to the primary coil bobbin, one on the low voltage side and one on the high voltage side. There is a fundamental and serious problem that the step-up transformer is large and expensive.

Without using the intermediate tap of the high voltage secondary coil having such a problem, the protective resistor in the conventional example is changed in connection so that it can be used as a voltage dividing resistor without changing the resistance value as in the present invention. Thus, if the impedance to ground (resistance) of the conductive mat is reduced, the unstable elements in Patent Documents 1 to 3 should be reduced. However, by such means, the location and use of the conductive mat can be reduced. There is no AC potential treatment device in the present world that suppresses the fluctuation of the peak value ratio between the positive voltage and the negative voltage of the AC applied to the living body accompanying the change in form.

Japanese Patent No. 2609574 JP 58-146361 A Japanese Patent No. 4217814 JP 2006-239032 A

An object of the present invention is to suppress fluctuations in the crest value ratio between the positive voltage and the negative voltage of alternating current applied to the living body that accompanies fluctuations in the location of the conductive mat and the usage pattern.

This device is a high-voltage secondary coil in an AC step-up transformer in which a primary coil is connected to an AC power source in constructing a potential therapy device that applies an AC high voltage to a living body from a conductive mat with insulating coating. A first voltage-dividing circuit in which a protective and voltage-dividing resistor is connected in series in a parallel circuit of a diode and a resistor directed to the high-voltage end between the high-voltage end of the ground and the ground potential end of the earth potential; A second voltage dividing circuit in which a resistor is connected in series to a diode is connected in series.

Next, a high-voltage alternating current with a peak value ratio between the positive voltage and the negative voltage of about 1: 3 is obtained from the voltage dividing output terminal between the voltage dividing circuits, and this high-voltage alternating current is directly applied to the conductive mat m. It is configured to be able to supply power as an applied alternating current, and the variation in the peak value ratio between the positive voltage and the negative voltage of the living body applied alternating current due to the variation in the location of the conductive mat and the usage pattern can be suppressed. The goal was achieved.

In the present invention, the protective and voltage dividing resistor provided in the first voltage dividing circuit eliminates the need for a series protective resistor only in the conductive mat in each of the conventional examples. ), And the fluctuation of the peak value ratio between the positive voltage and the negative voltage of the living body applied alternating current due to the variation of the place where the conductive mat is placed and the usage pattern can be suppressed. There is an excellent effect that it was made.

The reason why the present invention can achieve the above effect is that if the living body applied AC voltage at the partial pressure output terminal b is reduced due to the change in the arrangement place and usage pattern of the conductive mat, the first partial pressure is reduced according to this reduction. Although the voltage drop of the circuit increases, the voltage drop of the second voltage dividing circuit decreases, so that it can be assumed that the voltage drop can be suppressed. On the other hand, if the living body applied AC voltage rises, 1
Although the voltage drop of the voltage dividing circuit decreases, it can be estimated that the voltage increase can be suppressed because the voltage drop of the second voltage dividing circuit increases.

In short, according to the present invention, even if the living body applied AC voltage of the conductive mat m due to the change in the place of use of the conductive mat and the usage pattern fluctuates, the first and second partial pressures are offset so as to cancel this voltage fluctuation. As the voltage drop of the resistance in the circuit automatically increases and decreases each, the fluctuation of the peak value ratio between the positive voltage and negative voltage of the living body applied AC due to the location of the conductive mat and the change in usage pattern can be suppressed There is an excellent effect that the unstable elements in the conventional examples can be wiped off.

Next, an exemplary embodiment for carrying out the present invention will be described with reference to the drawings. The AC potential treatment device of the present invention conducts a sinusoidal AC high voltage having a frequency of, for example, about 50 to 100 Hz and a voltage having a peak value of about 14 KV. In constructing an electric potential treatment device for applying electric potential treatment from the mat m to the living body through the insulation coating, commercial alternating current itself or a general inverter power source which can generate an alternating voltage of the above frequency as shown in FIG. The primary coil L1 of the step-up transformer T is connected to the AC power source A by the circuit.
Connect.

1 is connected to a grounding end P2 of the high-voltage secondary coil L2 of the transformer T in FIG. 1 and a commercial AC input line, so that the grounding end P2 is connected to a pole transformer or the like. By connecting the ground terminal P2 to a ground bar or the like buried in the ground by the user, the potential of the ground terminal P2 is maintained at the ground potential.

On the other hand, between the high voltage terminal P1 and the ground terminal P2 of the secondary coil L2, as shown in FIG. 1, a high voltage diode D1 connected to the high voltage terminal P1 and a resistor R1 of about 18 MΩ · 3 W are connected in parallel. A first voltage dividing circuit B1 in which a protective and voltage dividing resistor Ro of about 10 MΩ · 3 W is connected in series to the circuit, and a second voltage resistor R2 of about 12 MΩ · 3 W connected in series to the high voltage diode D2 toward the ground terminal P2. The voltage divider circuit B2 is connected in series, and the values of these resistors are set corresponding to the constants of the resistors in Patent Document 1 described in paragraph 0010 above.

Next, after obtaining a high-voltage alternating current having a peak value ratio of positive voltage to negative voltage of about 1: 3 from the divided voltage output terminal b between the voltage dividing circuits B1 and B2 in FIG. Thus, the configuration is such that power can be directly supplied to the conductive mat m as a living body applied alternating current, and the ratio of the peak value ratio between the positive voltage and the negative voltage of the living body applied alternating current due to the location of the conductive mat and the variation of the usage pattern. It was able to be configured to suppress fluctuations.

However, the connection position of the parallel circuit of the diode D1 and the resistor R1 in the first voltage dividing circuit B1 and the protective voltage dividing resistor Ro in FIG. 1 or / and the diode D in the second voltage dividing circuit B2
2 and the resistor R2 may be connected to each other as shown in FIG.

That is, one end of the protective and voltage dividing resistor Ro is connected to the high voltage end P1 of the high voltage secondary coil L2 as shown in FIG. 2, and the other end of the resistor Ro and the voltage dividing output end b are connected in parallel. A circuit is connected or one end of the resistor R2 is connected to the voltage dividing output terminal b, and the other end of the resistor R2 and the ground terminal P are connected.
Even if a diode D2 is connected between 2 and 2, the same effect is obtained.

Since the AC potential treatment device according to the present invention has the above-described configuration, in order to use it, the patient's patient is placed on an insulating covering conductive mat m laid and insulated from the ground with respect to the floor of the house. When the affected part such as the waist is applied, a peak ratio of the positive voltage and the negative voltage can be applied at a predetermined ratio, for example, an AC high potential of about 1 to 3 can be applied through the insulating coating.

Specifically, the power supply voltage used in the embodiment of the present invention shown in FIG. 1 and the resistance values of the resistors R1, R2, and the protection-use voltage dividing resistor Ro are the power supplies used at the time of voltage measurement for each part of Document 1 in the paragraph 0010. A voltage and a resistance value corresponding to each resistance value were set, and the living body applied AC voltage e between the divided voltage output terminal b and the ground potential line E was measured under the same measurement conditions as described above.

First, the AC voltage of the transformer secondary coil L2 is set to 14 KV, the resistance R1 in parallel with the diode D1 is set to 18 MΩ · 3 W, the resistance value of the protective voltage dividing resistor Ro is set to 10 MΩ · 3 W, and the resistance R2 is set to 12 MΩ · 3 W, respectively. After that, the biological applied AC voltage e between the unloaded partial pressure output terminal b with the conductive mat m removed from the partial pressure output terminal b and the ground potential line E was measured by the oscilloscope, and as a result, the partial pressure output The negative voltage at the end b is 12.7 KV and the positive voltage is 4.0
At 7 KV, the peak value ratio between the positive voltage and the negative voltage was 1: 3.13.

Then, the conductive mat m is connected to the partial pressure output terminal b as shown in FIG. 1, and the partial pressure output terminal b and the ground potential line are used in a state where the living body applied alternating current is applied to the living body affected part through the insulating coating of the conductive mat m. E
The living body applied AC voltage e between was measured in the same manner as described above.

As a result, since the impedance of the conductive mat m in which the living body affected part is in close contact with the entire surface is about 2 MΩ as described above, the negative voltage of the divided output terminal b is 14 × 1/6 = 2.33 KV · the positive voltage is 0.82 KV, and the peak value ratio between the positive voltage and the negative voltage is 0.82: 2.33 = 1:
On the other hand, since the impedance of the conductive mat m on which one arm is placed is about 10 MΩ as described above, the negative voltage at the divided output terminal b is 14 × 1/2 = 7.0 KV · positive voltage Is
2.38 KV, and the peak value ratio between the positive voltage and the negative voltage is 2.38: 7.0 = 1: 2.9.
It became four.

Therefore, the variation difference of the crest value ratio between the positive voltage and the negative voltage of the living body applied alternating current due to the variation of the arrangement place of the conductive mat m and the usage pattern is 2.94-2.84 = 0.10. Since the fluctuation rate of the peak value ratio is only 0.34% with respect to the average value of the high value ratio of 2.89, the paragraph 00
13, the fluctuation ratio of the peak value ratio in Patent Document 1 of 15.5% in the present invention was almost zero, whereas the fluctuation ratio of the peak value ratio in the present invention was almost zero. The fluctuation of the peak value ratio between the positive voltage and the negative voltage of the AC applied to the living body due to the fluctuation could be suppressed.

The reason why the present invention can achieve the above-described effect is that the conductive mat m is disposed due to the increase in the capacitance between the conductive mat m and the living body affected part according to the location of the conductive mat m and the change in usage pattern.
If the living body applied AC voltage decreases, the voltage drop of the first voltage dividing circuit B1 increases in accordance with this decrease, but the voltage drop of the second voltage dividing circuit B2 decreases, so the voltage drop is suppressed. On the other hand, if the above-mentioned living body applied AC voltage rises due to the capacitance reduction, the voltage drop of the first voltage dividing circuit B1 decreases accordingly, but the voltage drop of the second voltage dividing circuit B2 decreases. Since the voltage increases, the voltage increase can be suppressed.

In short, according to the present invention, even if the living body applied AC voltage of the conductive mat m due to the change of the place where the conductive mat m is used or the usage pattern fluctuates, the first and second components are offset so as to cancel the voltage fluctuation. Since the voltage drop of the voltage circuits B1 and B2 automatically increase and decrease, fluctuations in the peak value ratio between the positive voltage and negative voltage of the AC applied to the living body due to changes in the location of the conductive mat m and the usage pattern can be suppressed. As a result, the unstable elements in the respective conventional examples could be wiped off.

However, in order to make the peak value ratio of the positive voltage and the negative voltage as close as possible to 1: 3, or to set the output voltage of the voltage dividing output terminal b as high as possible, the resistors R1 and R2, By appropriately selecting the resistance value of the protective and voltage dividing resistor Ro together with the voltage of the secondary coil high voltage end P1, the crest value ratio can be brought close to 1: 3, and the output voltage can be set. The details are omitted because they are design issues.
