Description
The present invention is a kind of by microcomputer-controlled electric therapeutic instrument.
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 Γ О Р О Д С К И И) and audio frequency-current therapy (sixties is not, China's Yang Guoliang), the waveform of the waveform of its electric current of intermediate frequency and low frequency modulations electric current is all sinusoidal wave, in view of sine-wave current is a kind of simple, basic simple harmonic oscillation electric current, its physiology and therapeutical effect mainly only depend on the conversion of its frequency and frequency and replace, thereby the not necessarily optimum waveform of stimulating current of sinusoidal wave form.In recent years the non-sinusoidal electric current of inventor's first Application, impulse waveform electric current is made modulation waveform, forms medium frequency pulse modulation stream therapy.Impulse waveform electric current is a kind of multi resonant electric oscillation, impulse wave is containing abundant harmonic components, just, as two or more electric current mixing stacks applied to apply than single electric current effective, the electric current of intermediate frequency of multiple impulse waveform modulation can meet the requirement of different situations to stimulating current better.
The generation great majority of the frequency of existing intermediate frequency therapy apparatus and waveform still use discrete electronic component or linear integrated circuit to realize, and in recent years existingly adopt digital circuit and microprocessor control, convert by number/touch the instrument being achieved.Retrieve DRP DE 3335849, that the data of waveform and frequency are placed in ROM, enumerator is visited and is taken out data output after D/A conversion to the address of ROM, this instrument can only do the one in electric current of intermediate frequency therapy---interference current therapy, there is no automatic program control output, there is no memory function.Another DRP DE 3301622, is also with numerical control amplitude and waveform, has the memory of storage treatment plan, same, the waveform of its output, and frequency kind is few, and this is a kind of low frequency therapy apparatus (frequency < 1000Hz).Below both just used microprocessor, instead of microcomputerized control, thus function and purposes few.US Patent No. 4424812, a kind of by microprocessor control implantable Programmable stimulator, also be the stimulator that belongs to low frequency category, with after surgical incision skin, stimulator being implanted, selected by external cyclelog remote control stimulating current parameter, in fact, the stimulation electrotherapy implanting, drawback is a lot, patient is with standing the misery of surgical incision and retaining for a long time in vivo the cost of a foreign body, ailing effect on can retarded original health, thereby can not be to commonly encountered diseases, frequently-occurring disease is done a large amount of applying, most cases is replaced by the neural electrostimulation of percutaneous.The multifunction electric stimulator (MULTI-STIM JOANCO U.S.A. production) of the U.S.'s commercially available a kind of microprocessor control at present, it can only export a kind of sinusoidal current modulation frequency (at this instrument, the muscle stimulator Russianmuscle stimuiator of Russia by name), other three kinds of functions are also to belong to low-frequency current category, be still with knob and switching manipulation single step and treat, there is no automatic program control function, there is no memory function.Also do not have up to now to collect various electric current of intermediate frequency in a machine especially with the multi-functional electric current of intermediate frequency therapeutic equipments of computer control.
The object of the invention is to adopt computer control, implement the treatment of Multifunction medium-frequency electric current, can there is the medium frequency pulse modulation stream that more modulation waveform has especially comprised that the inventor proposes, can produce modulation waveform arbitrarily, if the frequency range of resting frequence and low frequency modulations is wider, can adjust arbitrarily, there is memory function, can work out a kind of multistep program-recipe according to preferred plan in advance, and can expand and amendment prescription, the Automatic Program of writing out a prescription when treatment output, make easy and simple to handle, can export with dynamic two kinds of modes with general, adopt keyboard input parameter, operate with 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 Frequency are obtained by clock division, frequency stabilization, accurate, and wide frequency range, IF-FRE 1～10KHz, 10 gears can be optional, and Frequency 1～150Hz, can be optional, while carrying out preprogrammed storage prescribed treatment, also can expand this scope.
Modulation waveform has the multiple waveforms such as square wave 1, square wave 2, sharp wave 1, sharp wave 2, triangular wave, exponential wave, sine wave, adopts numerical control synthetic method, realizes by number/touch conversion, and waveform is true to nature, can produce random waveform.The modulating frequency current that multiple different wave forms can produce best stimulating effect to different situations, different tissues.
Remember in EPROM according to the multistep program-recipe of preferred plan establishment, as long as clout prescription options button, the automatically program of follow procedure output square wave group when treatment.Each prescription can hold 31 " steps ", each step all can change arbitrarily the parameter for the treatment of, this be by staff regulate machine button may not do and obtain, multistep program-recipe is in treatment unit time (as 20 minutes), convert in multiple times every treatment parameter, can make patient be difficult for producing adaptability, bring into play the most fully the several functions effect of modulating frequency current, improve therapeutic effect, the prescription of storage can be expanded, can rewrite, instrument stores four conventional prescriptions in advance, can also deposit four prescriptions or amendment prescription in for user's expansion.
This instrument is dual pathways output, can treat two patients simultaneously, as four electrodes of two passages are placed by intersecting, and strikes " dynamically " key, is output as dynamic disturbance electric current, while doing other electrotherapies, can select equally dynamical fashion output.
The parameters of instrument shows with numeral, this numeral also can be made clock display, 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 automatically cuts off electric current, show " End ", play out one section of soft melody simultaneously as warning.
Instrument can be exported electric current of intermediate frequency or the unmodulated electric current of intermediate frequency of modulation, and the former has the modulation systems such as continuous modulation, intermittently modulation, Frequency-variable Modulation and interrupted modulation, and it is adjustable that modulation five keeps off, the duration T of modulation waveform
1with T
2be 1～10 second adjustable, output peak point current > 100mA (load 500 Ω), with the mode regulation output current intensity of the increasing or decreasing of stroking, current intensity also can be contoured dynamic change output.
In conjunction with embodiment below, and with reference to accompanying drawing 1, the present invention is given to the more explanation of detail, the core component (1) of instrument is a 8-bit microcomputer.Memory (2) is equipped with contact and control complete machine all parts and makes the operation sequence software of co-ordination, and it is connected with computer and address latch (4) by bus.The data of multistep program-recipe pack in another piece memory (3), are also connected with computer and address latch (4) by bus.This memory can fill 8 prescriptions, each prescription for different common diseases according to preferred plan with regard to following parameter: step-length, resting frequence frequency f
