TECHNICAL FIELD OF THE INVENTION
The present invention relates to a high-potential generator for a therapeutic device used for applying a current-supplying stimulus to a living body by weakening the positive potential of an AC high-voltage half-wave and setting the negative potential to be strong.
[0002]
[Prior art]
As one of the therapeutic instruments, a high current of AC is applied by utilizing the capacitance between the living body and the ground, so that a weak current flows through the living body to promote the ionic effect, and the excitatory action by the positive AC voltage. And a sedative action by a negative voltage to the living body to enhance the metabolism of the living body, for example, by high-pressure alternating current for the purpose of normalizing the functions of various parts of the living body such as treatment of an affected part and maintenance of a healthy body. There is a potential therapy device.
[0003]
By the way, in general, the distribution ratio of electrons in air, water and the like existing in nature is assumed to be 25% for positive electrons and 75% for negative electrons. Therefore, the ideal ratio of positive and negative ions present in a healthy living body is 25%. On the other hand, it is said to be 75% negative.
[0004]
For this reason, in the high potential treatment device, the peak value ratio between the positive voltage and the negative voltage of the high-voltage alternating current applied to the living body is set to 1: 3 in order to match the ideal ratio of the positive and negative ions in the living body. In view of this point, a high-potential therapeutic device as shown in FIG. 4 has been proposed. This means that a positive voltage including a resistor r1 and a diode d1 in parallel with each other and a resistor r2 connected in series with the parallel circuit is provided at both ends of a high-voltage secondary coil (winding) L of an AC step-up transformer (transformer) t. A bleeder circuit is connected, the resistor r1 is a so-called Hi-Meg resistor having a high resistance of 50 to 60 MΩ, and the resistor r2 is a Hi-Meg resistor of 30 to 40 MΩ. Thus, the peak value ratio of the positive and negative potentials of the output alternating current by the bleeder circuit can be set to 1: 3 (for example, see Patent Document 1).
[0005]
Here, m is a conductive mat for applying an AC high voltage to a living body, L1 is a primary coil (winding) of a high-voltage up-flow transformer, AC is a commercial power supply, and d2 is a terminal side of the resistor r2 in the positive voltage bleeder circuit. , R indicates a high resistance for apparent grounding by an AC line, and r0 indicates a high resistance for protection by an AC line.
[0006]
[Patent Document 1]
Japanese Patent No. 2609574
[Problems to be solved by the invention]
However, in the high-potential therapeutic device disclosed in Patent Document 1, the resistance r1 has an extremely large resistance value of 50 to 60 MΩ and the resistance r2 has an extremely large resistance value of 30 to 40 MΩ. Even if there is, it is considered that the voltage drop cannot be ignored, and there is a problem that output fluctuation easily occurs due to the voltage drop and the output voltage is unstable. Further, there is a problem that the number of components increases.
[0008]
Therefore, the present invention can eliminate the need for a resistor having an extremely large resistance value, obtain a stable output, and can freely select the peak value ratio of the positive and negative potentials of the output AC. It is an object of the present invention to provide a high-potential generator for a therapeutic device that can be used as a medical device.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a high-potential generator for a therapeutic device in which an AC high voltage is applied to a conductive mat and applied to a living body on the conductive mat to perform treatment. An intermediate lead-out tap is provided between the winding start terminal and the winding end terminal of the secondary high-voltage winding, and the intermediate lead-out tap is provided with a positive AC in a direction from the winding start terminal to the winding end terminal of the secondary high-voltage winding. A high-voltage rectifier diode for rectifying an arbitrary voltage value of the voltage to direct current is connected, and a direct-current short circuit is formed in which the direct current flows into the secondary high-voltage winding from the intermediate lead-out tap to reach the high-voltage rectifier diode, In addition, the winding start terminal of the secondary high-voltage winding is grounded to the ground, and a DC short circuit is connected to the high-voltage rectifier diode through the winding end terminal of the secondary high-voltage winding through a resistor. Rectified by diode The direct current through the winding end terminal of the caused to flow into the secondary high voltage windings from the intermediate deriving tap secondary high-voltage winding and configured to reach the high-voltage rectifying diode than the resistor.
[0010]
When a positive voltage is induced in the direction from the winding start terminal to the winding end terminal of the secondary high voltage winding, any positive voltage value of the high voltage reaches the high voltage rectifier diode through the resistance from the winding end terminal, and The DC voltage is rectified by a diode, and the DC voltage is passed through the intermediate lead-out tap to the secondary high voltage winding. Further, the output voltage is reduced by a DC short circuit that reaches the high voltage rectifier diode via the winding end terminal and the resistor. It is supplied to the load side as half-wave alternating current.
[0011]
On the other hand, the negative voltage induced in the direction from the winding end terminal side of the secondary high voltage winding toward the winding start terminal is not reduced, and the voltage induced by the total number of turns of the secondary high voltage winding is reduced. It is output as it is.
[0012]
Therefore, it is possible to output a high-voltage AC in which the peak value of the positive voltage is small and the peak value of the negative voltage is large.
[0013]
In addition, by changing the position of the intermediate lead-out tap provided between the winding start terminal and the winding end terminal of the secondary high-voltage winding so that the number of short-circuit turns can be changed, the position of the intermediate lead-out tap can be changed. Since the peak value of the positive voltage half-wave output from the secondary high-voltage winding can be set freely, the peak value ratio with the negative voltage half-wave having a constant output voltage can be set freely.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0015]
FIG. 1 shows an embodiment of the high potential generator for a therapeutic device according to the present invention. When a commercial power supply AC 100 V is applied to a primary winding P, a secondary high-voltage winding T passes through a transformer closed magnetic circuit core. A step-up transformer as a compound-winding transformer capable of inducing a high voltage on the line S. The secondary high-voltage winding S has a winding from a winding start terminal SL0 to a winding end terminal SL2. An intermediate tap tap SL1 is provided at an intermediate portion of the line S so that its position can be changed, and the number of turns between the intermediate tap tap SL1 and the winding end terminal SL2 can be freely changed by changing the position of the intermediate tap tap SL1. Make it configurable.
[0016]
A high-voltage rectifier diode D for rectifying an AC positive voltage to DC is connected to the intermediate lead tap SL1 so that the direction toward the intermediate lead tap SL1 is forward, and the high-voltage rectifier diode D is connected to the high-voltage rectifier diode D. When the winding end terminal SL2 of the secondary high voltage winding S is connected through the resistor R1 and a positive voltage is induced in the direction from the winding start terminal SL0 to the winding end terminal SL2 of the secondary high voltage winding S, an arbitrary voltage is applied. The positive voltage value reaches the high-voltage rectifier diode D via the resistor R1 from the winding end terminal SL2 of the secondary high-voltage winding S, and is rectified into DC here, and flows into the secondary high-voltage winding S from the intermediate lead-out tap SL1. By forming a DC short circuit A from the resistor R1 to the high voltage rectifier diode D via the winding end terminal, the resistor R1 is connected to prevent the short circuit current generated in the DC short circuit A from becoming excessive. It is assumed that functions as a protective resistance that.
[0017]
Further, the resistor R1 is connected to the conductive mat M via the resistor R2, and the remaining AC positive voltage whose potential has dropped due to the DC short circuit current generated by the DC short circuit A is sent to the conductive mat M through the resistor R2 as a low voltage. To do.
[0018]
One end of an apparent grounding resistor R is connected to the winding start terminal SL0 of the secondary high voltage winding S, and the other end of the resistor R is connected to the winding start terminal of the primary winding P. It is connected to the P0 side and is grounded to the ground (earth) E on an extension of the power supply terminal U connected to the winding start terminal P0 of the primary winding P.
[0019]
Further, in order to be able to switch the output voltage of the secondary high voltage winding S, the primary winding P has two input taps PH and PL having different numbers of windings from the winding start terminal P0. And a switch SW for switching the input from the power supply terminal V paired with the power supply terminal U connected to the winding start terminal P0 side with the input taps PH and PL. When the commercial power supply AC100V is connected to V, the switch SW is switched between the input taps PH and PL to change the transformation ratio between the primary winding P side and the secondary high voltage winding S side of the step-up transformer T. For example, when the switch SW is connected to the input tap PH, 100% output voltage is obtained on the secondary high-voltage winding S side. On the other hand, when the switch SW is switched to the input tap PL side, High pressure The output voltage of the line S side are to be able to be 50%.
[0020]
Symbol C denotes a capacitance between the conductive mat M and the ground (earth) E, and the resistor R2 denotes a protection resistor for adjusting a high-voltage current flowing through the capacitance C between the conductive mat M and the ground E. Will function as
[0021]
When the high potential generator for a therapeutic device of the present invention having the above-described configuration is used, the position of the intermediate lead-out tap SL1 of the secondary high voltage winding S is set to a required position between the winding start terminal SL0 and the winding end terminal SL2. In addition, the conductive mat M is laid on an indoor floor or bed in a state of being wrapped with an insulating sheet or the like so that the conductive mat M can be used as a capacitance electrode for the ground E.
[0022]
In this state, when the switch SW is connected to the input tap PH of the primary winding P of the step-up transformer T, 100 V of commercial power is applied between the power terminals U and V, and accordingly, the primary voltage of the step-up transformer T Since the winding start terminal P0 and the input tap PH of the winding P are excited, a high-voltage alternating current of 100% output voltage is induced in the secondary high-voltage winding S via the transformer closed magnetic path iron core. A positive voltage is induced in the direction from the winding start terminal SL0 to the winding end terminal SL2 of the next high voltage winding S. In this case, a part of the positive voltage of the positive voltage reaches the high voltage rectifier diode D from the winding end terminal SL2 of the secondary high voltage winding S through the resistor R1 and is rectified by the diode D into DC. A DC short-circuit circuit A that flows into the secondary high-voltage winding S from the intermediate lead-out tap SL1 of the high-voltage winding S, and from the intermediate lead-out tap SL1 to the high-voltage rectifier diode D via the winding end terminal SL2 and the resistor R1. Is formed, and the short-circuit current formed in this case can be easily circulated without being blocked by the inductance of the secondary high-voltage winding S because it is a direct current. Accordingly, the intermediate short-circuit tap SL1 of the secondary high-voltage winding S and the winding end terminal SL2 have the same potential due to the DC short-circuit current. Therefore, the potential of the winding end terminal SL2 becomes equal to the potential of the intermediate winding tap SL1. You will be able to descend.
[0023]
In addition, even if the positive voltage half-wave induced in the direction from the winding start terminal SL0 toward the winding end terminal SL2 is directed to the high voltage rectifier diode D from the intermediate lead-out tap SL1 of the secondary high voltage winding S, Since it is blocked by the opposite polarity, only the above-mentioned action occurs.
[0024]
Accordingly, of the positive voltage half-wave alternating current induced in the direction from the winding start terminal SL0 to the winding end SL2 of the secondary high voltage winding S, the positive voltage half-wave alternating current reaches the high voltage rectifier diode D from the winding end terminal SL2, is rectified to DC and drops. By changing the position of the intermediate lead-out tap SL1, for example, the voltage value to be made becomes −66% (− ／) with respect to the positive voltage output induced by the total number of turns of the secondary high voltage winding S. When a positive voltage is induced in the direction from the winding start terminal SL0 to the winding end terminal SL2 of the secondary high-voltage winding S as described above, the resistance R1 is set from the winding end terminal SL2. And the positive voltage half-wave output to the conductive mat M via the resistor R2 is 34% (１ ／) of the positive voltage output induced by the total number of turns of the secondary high voltage winding S.
[0025]
On the other hand, when a negative voltage is induced in the direction from the winding end terminal SL2 of the secondary high voltage winding S to the winding start terminal SL0, the negative voltage half-wave alternating current causes the winding of the secondary high voltage winding S of the transformer. Since the current flows only from the end terminal SL2 to the winding start terminal SL0, the total voltage of 100% induced by the total number of turns of the secondary high-voltage winding S does not decrease as a negative voltage, and the resistance R increases from the winding start terminal SL0. The power is supplied to the conductive mat M by the capacitance C via the ground E via the winding start terminal P0 of the primary winding P and an extension of the power supply terminal U.
[0026]
As a result, the high-voltage output AC voltage is applied to the conductive mat M so that the ratio of the peak values of the positive and negative voltages is 1: 3. Therefore, by contacting the conductive mat M with, for example, a required part of a living body, for example, an affected part, the high pressure is applied to the affected part of the living body in a state where the ratio of the peak value of the positive / negative voltage is 1: 3. The positive and negative electric fields of the AC half-wave are applied, and the conduction stimulation is performed, so that the treatment of the affected part of the living body is performed.
[0027]
Similarly, when the position of the intermediate lead-out tap SL1 is changed by the DC short circuit A so that the voltage drop at the winding end terminal SL2 of the secondary high-voltage winding S becomes −75% of the positive voltage, the remaining While a positive voltage of 25% is output to the conductive mat M via the resistor R2, the negative voltage induced in the direction from the winding end terminal SL2 to the winding start terminal SL0 of the secondary high voltage winding S is 100% is supplied to the conductive mat M by the resistance R from the winding start terminal SL0, the winding start terminal P0 of the primary winding P, and the extension line of the power supply terminal U via the ground E without reduction. Become. Therefore, in this case, the ratio between the peak values of the positive voltage and the negative voltage can be set to 1: 4.
[0028]
Next, as shown by a two-dot chain line in FIG. 1, when the power supply terminal V is connected to the input tap PL side of the primary winding P by the switch SW, the commercial power supply AC100V is applied between the power supply terminals U and V. As a result, the winding start terminal P0 of the primary winding P of the step-up transformer T is excited between the input tap PL, and in this case, a high-voltage AC current of 50% output voltage is applied to the secondary high-voltage winding S. Is induced. At this time, on the secondary high voltage winding S side, the positive voltage half-wave is dropped to 33% of the total voltage induced by the total number of turns of the secondary high voltage winding S in the same manner as described above. The negative voltage half-wave is output to the conductive mat M while the 100% full voltage induced by the total number of turns of the secondary high voltage winding S is output to the conductive mat M. In this case, a high output AC voltage having an output voltage of 50% with a peak value ratio of the positive / negative voltage of 1: 3 is applied.
[0029]
As described above, according to the high-potential generator for a therapeutic device of the present invention, the position of the intermediate lead-out tap SL1 in the secondary high-voltage winding S of the step-up transformer T is changed from the intermediate lead-out tap SL1 to the secondary high-voltage winding S. Of the winding end terminal SL2, the resistor R1, and the high-voltage rectifier diode D, the DC short circuit flows again into the DC short circuit A which reaches the intermediate lead tap SL1, so that the potential of the winding end terminal SL2 becomes the same potential as the intermediate lead tap SL1. Of the positive voltage half-wave with respect to the positive voltage output induced by the total number of turns of the secondary high-voltage winding S, for example, -66% (− ／). By setting the position in advance, a high-voltage output AC voltage having a peak value ratio of positive / negative voltage of 1 to 3 can be applied to the conductive mat M.
[0030]
In the above, since the resistor R1 only needs to act as a protection resistor for preventing the DC short circuit current generated in the DC short circuit A from becoming excessive, it is possible to establish a circuit with a resistance value of about 5 MΩ. Therefore, it is possible to reduce the resistance value of the constituent circuit to about 1/20 of that of the conventional high-potential generating circuit using the high-meg resistors r1 and r2. In addition to being able to be suppressed as compared with the conventional case, the peak value ratio of the positive / negative voltage is determined by the experimental results of FIGS. 2 (a), (b), (c), (d) and FIGS. As can be seen from FIG. 4, since the variation from the set value can be extremely reduced, the effect of treating the affected area can be stably increased. Further, the number of parts can be reduced as compared with the related art.
[0031]
In addition, since the position of the intermediate lead tap SL1 can be freely set, the position of the intermediate lead tap SL1 is changed, and a DC short circuit current flows through the DC short circuit A formed on the secondary high voltage winding S side. Of the positive voltage half-wave due to the total voltage of the secondary high-voltage winding S is -75% (-3/4) or -80% (-4/5) with respect to the positive voltage output induced by the total number of turns. ), The remaining positive voltage output can be as low as 25% or 20%. On the other hand, the ratio of the peak value of the positive voltage to the negative voltage can be made to correspond to a wide range such as 1: 4 or 1: 5 by the ratio with the negative power output induced by the total number of turns of the secondary high voltage winding S. By selecting the position of the intermediate tap SL1, it is possible to freely set the peak value ratio between the positive and negative voltages.
[0032]
Furthermore, in order to change the output voltage of the secondary high-voltage winding S between 100% and 50% by changing the transformation ratio between the primary winding P and the secondary high-voltage winding S in the primary winding P. By switching the input taps PH and PL with the switch SW, it is possible to easily switch the output voltage to the conductive mat M in accordance with the voltage desired when treating the affected part of the living body.
[0033]
Note that the present invention is not limited to only the above-described embodiment, and the step-up transformer T requires a commercial power supply AC of 100 V connected to the primary side to obtain a high voltage to be applied to the conductive mat M. If the intermediate output tap SL connected to an arbitrary number of turns of the selected winding portion of the secondary high-voltage output winding is provided, May be used. The primary winding P has input taps PH and PL for allowing the voltage output induced on the secondary high voltage winding S to be switched between 100% and 50%. Is shown, but a single input tap is used so that a high voltage of a constant voltage output is induced from the secondary high voltage winding S side, or other than 50% instead of the input tap PL. An input touch that provides constant voltage output Or more than two input taps in addition to the input tap PH so that the output voltage on the secondary high-voltage winding S side can be switched in more stages. It goes without saying that various changes can be made without departing from the spirit of the invention.
[0034]

In the apparatus shown in FIG. 1, the position of the intermediate lead-out tap SL1 in the secondary high-voltage winding S is set so that the peak value ratio of the positive / negative voltage of the high-voltage AC output to the conductive mat M can be 1: 3. Of the positive voltage half-wave induced in the secondary high voltage winding S due to the formation of the DC short circuit A via the resistor R1 and the high voltage rectifier diode D between the intermediate lead tap SL1 and the winding end terminal SL2. The voltage drop is set to be -66%, and the peak values of the positive and negative voltages actually measured when there is no load are, as shown in FIG. 2A, a positive potential of +3740 V and a negative potential of -12540 V (positive and negative voltages).

[0035]
【The invention's effect】
As described above, according to the present invention, the following excellent effects are exhibited.
(1) In a high potential generator for a therapeutic device, in which an AC high voltage is applied to a conductive mat and applied to a living body on the conductive mat to perform treatment, a winding start terminal of a secondary high voltage winding of a step-up transformer. From the winding start terminal to the winding end terminal, and an arbitrary positive AC voltage value in the direction from the winding start terminal to the winding end terminal of the secondary high-voltage winding is converted to DC at the intermediate lead tap. A high-voltage rectifier diode for rectification is connected to form a DC short-circuit circuit for flowing direct current from the intermediate lead-out tap to the secondary high-voltage winding to reach the high-voltage rectifier diode. A configuration in which the first terminal is grounded to the ground, and furthermore, a DC short circuit is connected to the high voltage rectifier diode through the end terminal of the secondary high voltage winding through a resistor, and the DC rectified by the high voltage rectifier diode is an intermediate output tap. More secondary When the positive voltage half-wave is induced in the secondary high-voltage winding, it is configured such that when the positive voltage half-wave is induced in the secondary high-voltage winding, the voltage reaches the high-voltage rectifier diode through the winding end terminal of the secondary high-voltage winding. The positive voltage is rectified to DC by a high voltage rectifier diode, and then flows into the secondary winding from the intermediate lead-out tap. The DC terminal is short-circuited by the DC short circuit from the end terminal of the secondary high voltage winding to the resistor and the high voltage rectifier diode. Since the current can flow, the output voltage of the positive half-wave can be dropped to a required voltage based on the installation position of the intermediate lead-out tap in the secondary high-voltage winding. Since the output voltage of the positive voltage half-wave can be reduced as compared with the output voltage of the negative voltage half-wave induced by the total number of turns, the peak value of the positive voltage becomes small and the peak value of the negative voltage becomes large. High It can be output AC. At this time, since the resistor may be used as a protection resistor for preventing a short circuit current generated in the DC short circuit from becoming excessive, a high-Meg resistor r1, like a conventional high voltage generating circuit for a high voltage therapy device, may be used. As compared with the case where r2 is used, the resistance value of the constituent circuit can be reduced to about 1/20, so that the output fluctuation due to the voltage drop can be suppressed smaller than before and the loss can be reduced. And the fluctuation of the peak value ratio of positive / negative voltage can be extremely reduced.Therefore, when applying a high-potential therapeutic device to a living body, the functions of various parts of the living body such as treatment of an affected part and maintenance of a healthy body Can be stably and significantly increased. Further, the number of parts can be reduced as compared with the related art.
(2) Varying the position of the intermediate lead-out tap by changing the position of the intermediate lead-out tap provided between the winding start terminal and the winding end terminal of the secondary high-voltage winding so that the number of short-circuit turns can be changed. Thus, the peak value of the positive voltage half-wave output from the secondary high-voltage winding can be set freely over a wide range, so that the peak value ratio with the negative voltage half-wave having a constant output voltage can be set freely.
