Detailed Description
Specific embodiments of the present invention will now be described with reference to the accompanying drawings.
The potential therapeutic apparatus comprises an oscillator and a step-up transformer BK, wherein a primary coil of the step-up transformer BK is provided with a plurality of taps, and each tap is connected with the output end of a power amplifier through a multi-bit switch HK; the two ends of the secondary coil of the step-up transformer BK are respectively connected with an electrode J1, one electrode is arranged in the insulating cushion, and the other electrode is arranged above the insulating cushion or connected with the ground.
The oscillator comprises an operational amplifier A1, wherein the inverting input end of the operational amplifier A1 is grounded through a capacitor C1, a resistor R3 and a variable resistor R4 are connected in series between the inverting input end of the operational amplifier A1 and the output end of the operational amplifier A1, the non-inverting input end of the operational amplifier A1 is connected with a positive power supply V+ through the resistor R1, the inverting input end of the operational amplifier A1 is grounded through a resistor R2, and a resistor R5 and a photoresistor of an optical coupler GE are connected in series between the non-inverting input end of the operational amplifier A1 and the output end of the operational amplifier A1.
The primary coil of the current transformer LK is connected in series in the secondary loop of the boost transformer BK, one end of the secondary coil of the current transformer LK is connected with the input end of the signal amplifier, the other end of the secondary coil of the current transformer LK is grounded, the output end of the signal amplifier is connected with the input end of the rectifier, the output end of the rectifier is grounded through a capacitor C2, the output end of the rectifier is connected with the anode of the light emitting diode of the optocoupler GE through a resistor R6, and the cathode of the light emitting diode of the optocoupler GE is grounded. The signal amplifier amplifies the current signal, and the rectifier converts the current signal output by the signal amplifier into a direct current voltage.
In order to observe the frequency change conveniently, a frequency meter is connected between the output end of the operational amplifier A1 and the ground, and in order to observe the current of a human body conveniently, a microammeter is connected in series in a secondary coil loop of the step-up transformer.
The circuit principle is that when the output end of the operational amplifier A1 is at a high level (approximately equal to the amplitude of the positive power supply V < + >), the capacitor C1 is charged through the resistor R3 and the variable resistor R4, the voltage of the inverting input end of the operational amplifier A1 is increased, when the voltage of the inverting input end is larger than the voltage of the non-inverting input end, the output end of the operational amplifier A1 is changed to a low level (equivalent to the ground), the capacitor C1 is discharged through the resistor R3 and the variable resistor R4, the voltage of the inverting input end of the operational amplifier A1 is reduced, and when the voltage of the inverting input end is smaller than the voltage of the non-inverting input end, the output end of the operational amplifier A1 is at a high level, so that oscillation is formed; the oscillation frequency is related to the resistor R3, the variable resistor R4 and the capacitor C1, and is also related to the resistor R1, the resistor R2, the resistor R5 and the photoresistor, and the series value of the resistor r1=r2=r5 and the photoresistor is set, when the output end of the operational amplifier A1 is in a high level state, the non-inverting input end of the operational amplifier A1 is about 2/3 of the amplitude of the positive power supply v+, when the output end of the operational amplifier A1 is in a low level state, the non-inverting input end of the operational amplifier A1 is about 1/3 of the amplitude of the positive power supply v+, and the voltage difference in the two states is 1/3 of the amplitude of the positive power supply v+, if the photoresistor resistance value becomes smaller, the voltage difference in the two states is increased, and vice versa; when the resistor R3, the variable resistor R4, and the capacitor C1 are unchanged, the oscillation frequency decreases as the resistance of the photoresistor decreases.
The boost transformer load is capacitive in nature and the capacitive load is characterized by a higher capacitive reactance at lower applied frequencies and vice versa. When the patient has effect during treatment, the dielectric constant of the tissue in the patient body tends to increase, which is equivalent to the increase of capacitance (the human body can be seen as electrolyte between electrodes), the output current of a secondary loop of a capacitance increasing step-up transformer increases along with the increase of the output current, the current of a light emitting diode of the photocoupler GE increases through the functions of a current transformer, a signal amplifier and a rectifier, the resistance value of a photoresistor decreases, and the resistance value of the photoresistor decreases to reduce the oscillation frequency of an oscillator.
In use, a person sits on the insulating seat cushion and toggles the multi-position switch HK to select a voltage (e.g., 5000V) and adjusts the variable resistor R4 to select an upper limit frequency (e.g., 70 HZ). The voltage is kept unchanged in a course of treatment, and the dielectric constant of the tissue in the body has a tendency to rise (namely, the physique of the human body is improved) in the treatment process, so that the frequency is automatically reduced.
