Abstract
A kind of low-frequency electric pulse quick-acting recovery apparatus, its pulse generator can produce two kinds of first-harmonics and modulating wave respectively, and but mixing forms the frequency modulation on pulse square wave of two groups of different frequencies, two kinds of frequencies can be changed use mutually, overcome user a certain frequency is produced adaptability and causes the bad problem of therapeutic effect.And this machine has used hot compress simultaneously, makes therapeutic effect obviously strengthen quickening.This mechanism causes this not high, is suitable for and promotes the use of.
Description
The invention belongs to the Medical Instruments of physiotherapy.
At present, utilize electric pulse as the instrument of physiotherapy and rehabilitation means in the medical profession extensive use, instrument multi-form and structure is also more and more.In the point electric impulse therapeutic apparatus in low-frequency range, adopt the technology of frequency modulation output to show quite ideal curative effect.But adopt the output of frequency modulation output instrument to have only single-frequency owing to most of, and human body cause the effect of instrument and the scope of application to be affected to the very strong adaptability of the normal generation of the stimulation of a certain frequency.And minority can be exported the instrument one of a plurality of frequencies and comes complex structure, cost height, is difficult for popularizing, and secondly for people's daily health caring rehabilitation, also there is no need to possess so much frequency.In addition, this type of therapeutic equipments only possesses a kind of in electric pulse or the heating function mostly, also has influence on the further raising of curative effect.
The objective of the invention is to design a kind of physiotherapeutic instruments that has low-frequency electric pulse output and tool hot compress function concurrently, overcome the problem of human body, and improve the curative effect of using instrument a certain frequency adaptability.
The present invention realizes its task as follows: the integrated operational amplifier circuit in the pulse generator can produce two kinds of different first-harmonics and modulating wave respectively by control, and can make a kind of first-harmonic and another kind of corresponding modulating wave mixing respectively, form two groups of different frequency modulation on pulse square waves; Control a kind of first-harmonic and modulating wave by another piece time-base integrated circuit and automatically switch to the first-harmonic and the corresponding modulating wave of another state simultaneously, form frequency modulation on pulse square wave with another frequency.The present invention also has heater circuit and heating bag.
Rehabilitation instrument of the present invention can use the low-frequency electric pulse and the hot compress of two kinds of frequencies of continuous conversion to carry out the body local treatment simultaneously, the effect that have warming the meridian and promoting blood circulation, blood circulation promoting and blood stasis dispelling, enhances metabolism is particularly rapid to patient's therapeutical effect such as rheumatism, rheumatoid, hyperosteogeny, soft tissue injury, scapulohumeral periarthritis, lumbago and skelalgia, effect is remarkable.And this apparatus structure is uncomplicated, and manufacturing cost is lower.
Further specify the present invention below in conjunction with accompanying drawing:
Fig. 1 is a theory diagram of the present invention.
Fig. 2 is a circuit diagram of the present invention.
Fig. 3 is a panel sketch map of the present invention.
The integrated operational amplifier circuit N of pulse amplifier
1Can adopt 324 of four amplifiers, after modulating wave is produced as oscillating circuit by the amplifier II, through switching diode V
5Enter in the amplifier I, with the fundamental wave mixing that is produced as oscillating circuit by the amplifier I, output waveform is the pulse square wave of frequency modulation.RP
1In order to fine setting modulation wave frequency.The frequency modulation on pulse square wave of output is through the RP of amplifying circuit
2After regulating base voltage, by high power valve V
7Amplify, again through output pulse transformer T
2Output, output waveform is unidirectional frequency modulation on pulse sharp wave.Output termination two pole pieces, the output pulse strength is shown by voltmeter.Regularly change-over circuit is by time-base integrated circuit N
2Form N with element such as control relay KA
2Can adopt 555.Break-make by KA is controlled N
1Oscillating capacitance insert, thereby make pulse generator produce the frequency of two groups of different conditions.Timing control circuit is by time-base integrated circuit N
3, relay K B, time switch SW
1Form with the elements such as resistance of different resistances.N
3Can use 555 time base circuits, SW
2It is reset switch.Heater circuit has controllable silicon 9, low-voltage AC is carried out halfwave rectifier supply with heating bag E, RP
3Be the potentiometer of control heating current, size of current is shown by dc milliammeter.Power circuit is by mains transformer T
1, bridge rectifier V
1-V
4, three end stable state integrated circuit N
4Elements such as (can adopt 7815) is formed, and provides running voltage to circuit at different levels, and SB is the on and off switch of tape light, XS
1It is the four-core accessory power outlet.
Temperature, intensity and frequency knob are arranged on housing face-plate of the present invention, rotate them and can adjust RP respectively
3, RP
2, RP
1Value; When pressing a certain required treatment time during button, SW
1Promptly connect with pairing resistance.Also have the voltmeter of indicating impulse intensity and the ammeter of expression heating current size to show on the panel.
When use is of the present invention, earlier electrode is placed affected part, it is coated outside it to generate heat, again the plug of electrode and heating bag is inserted the accessory power outlet of this machine, press the button of required treatment time, and turn temperature, intensity, frequency knob get final product begin treatment to desired value respectively.When continuing another patient treatment with this machine, press reset switch earlier, repeat above step again when not breaking away from power supply.
