Description
The present invention is a kind of computer mid-frequency electrotherapy device.
In the electric current of intermediate frequency therapy of 1-10KHz, interference current therapy (fifties, Austria Hans Nemec), sinusoidal current modulation frequency therapy (sixties, Soviet Union Я С Н О Г О Р О Д С К И И) and audio frequency-current therapy (end of the sixties, China's Yang Guoliang), the waveform of the waveform of its electric current of intermediate frequency and low frequency modulations electric current all is sinusoidal wave, in view of sine-wave current is a kind of simple, basic simple harmonic oscillation electric current, the conversion that its physiology and therapeutical effect mainly only depend on its frequency and frequency with alternately, thereby the sinusoidal wave form optimum waveform of stimulating current not necessarily.In recent years the non-sinusoidal electric current of inventor's first Application, promptly the impulse waveform electric current is made modulation waveform, constitutes medium frequency pulse modulation stream therapy.The impulse waveform electric current is a kind of multi resonant electric oscillation, impulse wave contains abundant harmonic components, just as two or more electric current is mixed stack use than single electric current use effective, the synthetic electric current of intermediate frequency of multiple impulse waveform can satisfy the requirement of different situations to stimulating current better.
The frequency of existing intermediate frequency therapy apparatus also is to use discrete electronic component or linear integrated circuit to realize with the generation great majority of waveform, and existing in recent years digital circuit and the microprocessor of adopting controlled, the instrument that is achieved by steering D/A conversion.Retrieved DRP DE 3335849, be that the data of waveform and frequency are placed among the ROM, the address of enumerator visit ROM is taken out data and is exported after the D/A conversion, this instrument can only be done a kind of-interference current therapy in the electric current of intermediate frequency therapy, do not have automatic program control output, do not have memory function.Another DRP DE 3301622 also is with numerical control amplitude and waveform, and the memory of storage treatment plan is arranged, and is same, the waveform of its output, and the frequency kind is few, and this is a kind of low frequency therapy apparatus (frequency＜1000Hz).Above both only has been to use microprocessor, rather than microcomputerized control, thereby function and purposes are few.U.S. Pat 4424812, be a kind of by microprocessor control implantable Programmable stimulator, it also is the stimulator that belongs to the low frequency category, with behind the surgical incision skin stimulator being implanted, select by external cyclelog remote control stimulating current parameter, in fact, the stimulation electrotherapy that implants, drawback is a lot, patient will and keep the cost of a foreign body in vivo for a long time with the misery of standing surgical incision, the effect of the slight illness on can retarded original health, thereby can not be to commonly encountered diseases, frequently-occurring disease is done a large amount of applying, and most cases is replaced by the neural electrostimulation of percutaneous.The multifunction electric stimulator (MULTI-STIM JOANCO U.S.A. production) of the at present commercially available a kind of microprocessor control of the U.S., it can only export a kind of sinusoidal current modulation frequency (in this instrument, the muscle stimulator Russian muscle stimulator of Russia by name), other three kinds of functions also are to belong to the low-frequency current category, be still with knob and switching manipulation single step and treat, do not have the automatic program control function, do not have memory function.Also there was not to collect the multi-functional electric current of intermediate frequency therapeutic equipments that various electric current of intermediate frequency are especially controlled with computer in a machine up to now.
The objective of the invention is to adopt computer control, implement multi-functional electric current of intermediate frequency treatment, can have the medium frequency pulse modulation stream that multiple modulation waveform has comprised that especially the inventor proposes, can produce modulation waveform arbitrarily, if the frequency range broad of resting frequence and low frequency modulations, can adjust arbitrarily, memory function is arranged, can work out a kind of multistep program prescription according to preferred plan in advance, and can expand and the modification prescription, prescription Automatic Program output during treatment, make easy and simple to handle, can adopt keyboard input parameter with general and dynamic dual mode output, operate with the man-machine conversation mode.This computer mid-frequency electrotherapy device can do general and dynamic disturbance electric current therapy, audio frequency-current therapy, sinusoidal current modulation frequency therapy and medium frequency pulse modulation stream therapy etc.Over thousands of kind on the waveform of energy array output makes to have clinical application widely.
Intermediate frequency of the present invention and low frequency frequency are obtained by clock division, frequency stabilization, accurate, and wide frequency range, IF-FRE 1～10KHz, 10 retainings can be chosen wantonly, and low frequency frequency 1～150Hz can choose wantonly, when carrying out preprogrammed storage prescribed treatment, also can expand this scope.
Modulation waveform has multiple waveforms such as square wave 1, square wave 2, sharp wave 1, sharp wave 2, triangular wave, exponential wave, sine wave, adopts the numerical control synthetic method, realizes that by number/touch conversion waveform is true to nature, can produce random waveform.The modulating frequency current that multiple different wave constituted can produce best stimulating effect to different situations, different tissues.
According to the multistep program prescription memory of preferred plan establishment in EPROM, as long as clout prescription options button, the program of the prescription of follow procedure output automatically ripple group during treatment.Each prescription can hold for 31 " steps ", each step all can change the parameter of treatment arbitrarily, this be by staff regulate the machine button may not do and obtain, multistep program prescription is in treatment unit time (as 20 minutes), the every treatment parameter of conversion repeatedly, can make patient be difficult for producing adaptability, the multiple function of fullest ground performance modulating frequency current, improve therapeutic effect, the prescription of storage can be expanded, can rewrite, instrument stores four prescriptions commonly used in advance, can also deposit four prescriptions in or revise prescription for user's expansion.
This instrument is dual pathways output, can treat two patients simultaneously, places as four electrodes of two passages are pressed to intersect, and strikes " dynamically " key, then is output as the dynamic disturbance electric current, when doing other electrotherapies, can select dynamical fashion output equally.
The parameters of instrument shows with numeral, this numeral also can be made clock and show, output current intensity except can from numeral show read, also having two row light emitting diodes to make sync level monitors, treatment finishes instrument and cuts off electric current automatically, show " End ", play out one section soft melody simultaneously as warning.
Instrument can be exported synthetic electric current of intermediate frequency or unmodulated electric current of intermediate frequency, and the former has modulation systems such as continuous modulation, intermittently modulation, Frequency-variable Modulation and interrupted modulation, and modulation five retainings are adjustable, the duration T of modulation waveform
1With T
2Be 1～10 second adjustable, output peak point current＞100mA(load 500 Ω), regulate output current intensity in the mode of the increasing or decreasing of stroking, current intensity also can be contoured dynamic change output.
