See Fig. 1, power circuit of the present invention partly is by a power supply V, on and off switch K3, and resistance R 11, electrochemical capacitor C6, capacitor C 7, light emitting diode D2 form.Also can form with a kind of two-supply circuit as prior art, but this dual power supply need be with one 9 volts battery, another is 3 volts a battery, so inconvenience when using, power consumption are big, and can't use alternating current, and power supply of the present invention generally can be 3 ± 0.4 volts a battery with DC voltage, easy to use, also can connect alternating current by socket J2 after using commutator, 220 volts of voltages are as power supply.
Modulation pulse generator of the present invention and scanning frequency pulse generator are to be 9015,5 resistance R 2-R6 by a slice dual time-base ic ICM7556 and transistor T 1 model, and 4 capacitor C 1-C4 form.Dual time-base ic also can be selected the ICM556 type for use, but its resistance, electric capacity also need be done corresponding adjustment, and its power supplys more than needing 4.5 volts, and power consumption more greatly.Because ICM7556 is a series of advantages such as have the input impedance height in the cmos circuit, power consumption is little, effect good, the power supply subject range is wide, is specially adapted to occasions such as low-power consumption, so the present invention selects the ICM7556 dual time-base ic for use.The pin of ICM is seen accompanying drawing 2, and it contains two identical time base circuits, and the equivalent function block diagram of each time base circuit is seen accompanying drawing 3.Transistorized model also can be selected D965,9013,9014,9018,8050 etc. for use.In order to be the best with supporting 9015 types of selecting for use of ICM7556.
Circuit of the present invention connects presses accompanying drawing 1.The 1-7 foot of ICM7556 is time base circuit I and resistance R 2-R4, capacitor C 1-C3 and transistor T 1 are formed pulse generator, produce rectangular wave at the 5th foot, its frequency is the low frequency of 3HZ ± 10%, (size of its frequency is by the resistance R of selecting 2,1 decision of R3 and capacitor C), remove to control the 10th foot of time base circuit II of the 8-13 foot of ICM7556.And capacitor C 1 two ends being discharged and recharged behind the signal isolated variable one of output and the corresponding triangular wave of modulating pulse by transistor T 1, modulation voltage removes to select to control the 11st foot of another time base circuit II.By time base circuit II (the 8-13 foot of ICM7556) and resistance R 5, R6, capacitor C 4 is formed the scanning frequency pulse generators.Because its forced resetting end (see figure 3) is controlled by the output square-wave pulse of time base circuit I, so the time base circuit II only just may be worked in the output pulse high level time of time base circuit I, again because its control end Vc(sees accompanying drawing 3) controlled by the triangular wave of T1 output, so do the control that its output pulse frequency of stage is subjected to T1 output triangular wave in the time base circuit II, will between frequency sweep ripple upper bound frequency and frequency sweep ripple lower bound frequency, do the automatic frequency sweep conversion.The mid frequency of its frequency sweep is by selected resistance R 5, R6 and capacitor C 4 decisions.Because the triangular wave of T1 output is corresponding with the square wave of time base circuit I, thus the output pulse of time base circuit II in a working time general automatic frequency sweep is once from low to high.
Then can make speed governing usefulness as in circuit, increasing resistance R 1 and K switch.
Power output amplifier of the present invention partly is that choosing is by 2 transistor Ts 2 and T3,2 pulse power amplifiers that resistance R 7, R8 and potentiometer W, capacitor C 5 and coupling transformer B form, the synthetic scanning frequency pulse that is subjected to that time base circuit II the 9th foot is produced carries out power amplification, and exports to therapeutic electrode by output plughole J1.Also can select for use a diode to replace transistor, as long as its resistance and electric capacity are done corresponding the adjustment.
In addition, also design the level indicating circuit of being made up of diode D1, resistance R 9, R10 and decibel meter in this circuit, to avoid causing the too high of coupling transformer B owing to unloaded, back-pressure influences the operate as normal of transistor T 2, T3 to resistance R 9 as load.K2 is frequency sweep/single-frequency permutator, makes this therapeutic instrument also can make single-frequency and uses.
What determined that this sweep frequency spectral treating apparatus produced by the selected in addition part model of the present invention is a kind of intermediate frequency frequency sweep wave spectrum.Its service behaviour intermediate frequency swept frequency range is 1.6~3.8KHZ ± 10%; The low-frequency pulse modulating frequency is 3HZ ± 10%; Output pulse amplitude is 0-14Vp-p ± 10% down for 1 kilohm at load resistance; Under 1 kilohm of load resistance, the output pulse current is 0-14mAp-p.
