Realize that the scheme that the purpose of this utility model is taked is: this therapeutic instrument has the housing of a splendid attire circuit board, and the outside of housing is provided with a bracing frame and the pole plate that contacts with the human body wound surface by lead.On the panel of housing, be provided with adjustment knob, frequency demonstration and the jack etc. of total power switch, display lamp, output amplitude, frequency.Enclosure interior is provided with filter rectifier, oscillating waveform generation circuit, power amplification circuit.In this utility model, therapeutic instrument adopt to exchange input 220V alternating current, produce voltage U 2, U3 through transformator B, by output two constant DC voltage V1, V2, V1 after rectification, the filtering is that reference voltage outputs on the pole plate JB1, and pole plate is the conductive silicon rubber plate, directly contacts with human body.V2 provides power supply for oscillating waveform generation circuit, the wave of oscillation that produces frequency adjustable by the oscillating waveform generator is input to power amplification circuit, amplification produces frequency through two-stage, all adjustable pulse voltage of amplitude outputs on another piece pole plate JB2, JB1 is used with pole plate, patient's wound surface is produced the impulse stimulation electric current, reach the effect of treatment.

Utilize accompanying drawing to further describe embodiment of the present utility model below.

Fig. 1 is a circuit diagram of the present utility model

Fig. 2 is the outline drawing of body utility model

Adopt the alternating current input to produce voltage U 2, U3 through transformation referring to Fig. 1, this utility model, by filtering, rectification circuit becomes constant DC voltage V1, V2 to alternating current, and is existing that each several part circuit division is as follows:

Filter rectifier is divided into two loops, first loop is by diode D1, bridge rectifier and capacitor C 1 parallel connection that D2, D3, D4 form, one terminates on the common wire, the other end links to each other with outfan power output contact CK1, bridge rectifier and capacitor C 2 parallel connections that second loop is made up of diode D5, D6, D7, D8, one terminates on the common wire, and the other end is connected on the branch road of potentiometer W1 and resistance R 10 parallel connections.

Oscillating waveform generation circuit: be to constitute two temporary steady-state circuits by two audion BG1, BG2 and relevant resistance R 1, R2, R3, R4 capacitor C 3, C4, diode D9, D10, electronic components such as D13, D14, audion BG1, BG2 adopt the mode of symmetrical reversal connection parallel connection to connect, resistance R 2, R3 join with audion BG1, BG2 base stage respectively, resistance R 1 connects audion BG1 colelctor electrode and plays metering function, impels diode D13 normally to show.Resistance R 4 connects audion BG2 colelctor electrode, and diode D14 is normally shown.In oscillating waveform generation circuit, circuit constantly changes between two temporarily steady states, forms the one after the other conducting and ends, and produces vibration thus, that is: first loop: BG1 is in cut-off state when audion, when BG2 was in conducting state, audion BG2 obtained base flow by resistance R 3, and capacitor C 4 is from the base flow of the charging current supply short time that resistance R 1 obtains, and link with the colelctor electrode of audion BG1, make audion BG2 vibration, produce waveform, by diode D10 output square wave.Second loop, BG2 is in cut-off state when audion, when BG1 is in conducting state, BG1 obtains base flow by resistance R 2, capacitor C 3 obtains the charging current of short time and links with the colelctor electrode of audion BG2 from resistance R 4, audion BG1 is vibrated, produce waveform, export square wave by diode D9.For the waveform that prevents diode D9, D10 output falls string, play the unidirectional steady effect of walking, diode D9, D10 adopt isolated mode, its anode respectively with audion BG1, the colelctor electrode of BG2 joins, and output waveform end and resistance R 5 are joined, and audion BG3 emitter stage is connected on the common wire.

After oscillating impulse produces, amplify through potentiometer W2 by audion BG3, adjusting is input to the power amplification utmost point, simultaneously, the waveform that produces, amplifying for prime provides the pulse low frequency signal, and the waveform pulsewidth of its this element circuit is 17ms, and time constant is come constant by the capacity of the resistance of resistance R 2, R3, capacitor C 3, C4.Frequency of oscillation is to adjust by regulator potentiometer W1, realizes 10-60 branch of the number of oscillation, and is stepless smoothly adjustable, and shows as amplitude by diode D13, D14.

Prime is amplified by audion BG3, resistance R 5, R6, R7, manostat DW serves as, be by resistance R 6, R7, dividing potential drop and through manostat DW voltage stabilizing to certain value as the bias current of amplifying stage, wherein, manostat Dw negative terminal is connected in the middle of resistance R 6, the placed in-line branch road of R7, and anode and common wire join, and resistance R 5 is joined with the base stage of audion BG3.Its major function is with clapp oscillator D9, the Weak pulse signal that D10 sends here after isolating is mutually amplified, signal voltage after the amplification is sent into power-amplifier stage through potentiometer W2 amplitude adjusted, and the reference voltage that triode BG3 prime is amplified, obtain certain value by manostat DW clamper, to guarantee the stability of audion BG3 amplifying stage.

Power-amplifier stage is finished by audion BG4, accept to hang oneself potentiometer W2 smooth adjustment signal voltage, through amplifying as power drive, wherein, the base stage of audion BG4 is regulated by potentiometer W2, and its emitter stage is by resistance R 8 current limlitings, be connected on the common wire, CK1, CK2 are as the contact that is connected with pole plate, and its output amplitude reaches 0-35 by potentiometer W2 adjusting and lies prostrate continuously adjustable pulse voltage, to satisfy patient's therapeutic purposes.

Referring to accompanying drawing 2, on case panel of the present utility model, be provided with total power switch 1, power supply indication 2, support 3, output amplitude adjustment knob 4, output frequency adjustment knob 5, frequency of oscillation demonstration 6, jack 7.In clinical practice, earlier lead is inserted "+" and "-" end of jack 7 respectively, the other end inserts on pole plate JB1, the JB2, energized 6, the display lamp 7 demonstration energized situations of passing through, regulate output frequency and output amplitude by knob 4,5 then, the size control of its adjusting feels according to the patient's, and to guarantee optimum curative effect, each treatment time decides on state of an illness weight.

The therapeutic instrument that adopts such scheme to make, and with special medicine---the soft flat liquid partner treatment of cicatrix, its curative effect is better, through clinical practice, have following effect: antipruritic, the antiinflammatory of easing pain, blood circulation promoting, improve histotrophic nutrition, recover the function that wound surface human body granulation promoting is removed cicatrix.The characteristics of this therapeutic instrument are that method is simple, evident in efficacy, have no side effect,, can avoid the cicatrix growth for beginning control after dark type of the dark II of burn and scald and the shallow III ° healing, to established hypertrophic cicatrix, can cure fully in 3-4 month, atrophic scar, keloid cooperate injection for curing and can obtain recovery from illness in pressure method 3-5 month, postoperative otch prevention cicatrix is treated and can be avoided the cicatrix growth in 10 days-1 month.

Its criterion of therapeutical effect, general treatment can be eliminated the pain shape of itching for 3-6 time, and treating 15 days-1 month its cicatrix color can be obviously thin out, and progressively disappears, treated 1 month-2 months, and the obvious deliquescing of cicatrix, promptly softening fast, treatment 2-3 month, cicatrix flattens gradually, can reach intended purposes
