Help improve therapeutic effect.
Detailed description of the invention
Fig. 1 is circuit diagram of the invention.
Specific embodiment
Now in conjunction with Detailed description of the invention a specific embodiment of the invention.
A kind of potential therapeutic instrument comprising oscillator, step-up transformer BK, the primary coil of step-up transformer BK are equipped with more
A tap, each tap are connected by the output end of multi-position switch HK and power amplifier；The secondary coil two of step-up transformer BK
End is connected separately with electrode J1, and an electrode is set in insulation cushion, and another electrode is set to above insulation cushion or connect with the earth.
The oscillator includes operational amplifier A1, and the inverting input terminal of operational amplifier A1 is grounded by capacitor C1,
Resistance R3 and variable resistance R4, operational amplifier A1 are in series between the inverting input terminal of operational amplifier A1 and its output end
Non-inverting input terminal positive supply V+ is connect by resistance R1, the inverting input terminal of operational amplifier A1 is grounded by resistance R2, operation
The photo resistance of resistance R5 and optocoupler GE are in series between the non-inverting input terminal of amplifier A1 and its output end.
The primary coil of current transformer LK is in series in the secondary loop of step-up transformer BK, current transformer LK's
The input terminal of one termination signal amplifier of secondary coil, the other end ground connection of the secondary coil of current transformer LK, signal are put
The input terminal of the output termination rectifier of big device, the output end of rectifier are grounded by capacitor C2, and the output end of rectifier passes through
Resistance R6 connects the anode of the light emitting diode of optocoupler GE, the minus earth of the light emitting diode of optocoupler GE.Signal amplifier is to electricity
Stream signal amplifies, and signal amplifier output current signal is converted to DC voltage by rectifier.
For convenience of observed frequency situation of change, it is connected to frequency meter between the output end and ground of operational amplifier A1, for side
Just the electric current for observing human body, is in series with microampere meter in the secondary coil circuit of step-up transformer.
Circuit theory is, when the output end of operational amplifier A1 is high level (amplitude for being approximately equal to positive supply V+), to lead to
It crosses resistance R3 and variable resistance R4 to charge to capacitor C1, the voltage of the inverting input terminal of operational amplifier A1 increases, when reverse phase is defeated
Enter end voltage be greater than non-inverting input terminal voltage when, the output end of operational amplifier A1 becomes low level and (is approximately equivalent to connect
Ground), capacitor C1 is discharged by resistance R3 and variable resistance R4, the voltage decline of the inverting input terminal of operational amplifier A1, reverse phase
When the voltage of input terminal is less than the voltage of non-inverting input terminal, the output end of operational amplifier A1 is high level, and oscillation is consequently formed；
Frequency of oscillation is removed with resistance R3, variable resistance R4 and capacitor C1 phase outside the Pass, also with resistance R1, resistance R2, resistance R5 and light
Quick resistance is related, if resistance R1=resistance R2=resistance R5 and photo resistance series value, when the output end of operational amplifier A1 is
When high level state, the non-inverting input terminal of operational amplifier A1 is about the 2/3 of the amplitude of positive supply V+, when operational amplifier A1's
When output end is low level state, the non-inverting input terminal of operational amplifier A1 is about the 1/3 of the amplitude of positive supply V+, two states
Under voltage difference be positive supply V+ amplitude 1/3, if photo resistance becomes smaller, the voltage difference under two states be will increase,
Vice versa；In the case where resistance R3, variable resistance R4 and capacitor C1 constant, the resistance value of photo resistance, which becomes smaller, can make to vibrate
Frequency reduces.
Step-up transformer load is capacitive properties, and the characteristics of capacity load is that the frequency of application is lower, and its capacitive reactance is bigger,
Vice versa.When patient is effective during treatment, the dielectric constant of in-vivo tissue has raised trend, this is equivalent to capacitor
It measures (human body can be seen as interelectrode electrolyte) to increase, capacitance increases step-up transformer secondary loop output electric current and increases therewith
Greatly, increase the electric current of the light emitting diode of optocoupler GE, light
The resistance value of quick resistance reduces, and the reduction of the resistance value of photo resistance reduces the frequency of oscillation of oscillator.
In use, people is sitting on insulation cushion, multi-position switch HK selection voltage (such as 5000V) is stirred, adjusts variable resistance
R4 selects upper limiting frequency (such as 70HZ).Keep voltage constant in a course for the treatment of, over the course for the treatment of, the dielectric of in-vivo tissue
Constant is if any raised trend (i.e. the constitution of people makes moderate progress), then frequency declines automatically, due to human body matter over the course for the treatment of
Improvement be a progressive process, and the automatic decline of frequency is also a progressive process, this makes one physical efficiency and adapt to frequency to change
Become, is conducive to improve therapeutic effect.
