Abstract
The present invention relates to a power stepless self-increasing and surge output high-stability equilibrium-induction therapeutic apparatus. It is an improvement on the existent power self-increasing equilibrium-induction therapeutic apparatus, and is characterized by that said invention uses the specific circuits of high-accuracy large-dynamic adjustable voltage-stabilizing circuit and switching type pulse power-amplification circuit, and overcomes several disadvantages of existent marketed equilibrium-induction apparatus, and provides an equilibrium-induction therapeutic apparatus which not only can linearly self-increase its output power, but also have high stability at the same time of the production of large fluctuation of input utility power and output load, and make patient not easy to be tired and have output blocking protection function.
Description
The present invention is that a kind of power is from the high voltage that increases, the improvement of low frequency electronic therapeutic instrument (being commonly called as electrotherapeutic apparatus).
Electrotherapeutic apparatus be a kind of according to the traditional Chinese medical science " theory of channels and collaterals " and modern times " bioelectronics moving equilibrium theory " manufacture and design can output HIGH voltage, low-frequency modernized Chinese traditional treatment equipment, be the scientific instrument of realizing acupuncture, massage, qigong electronization, specially control various chronic diseases and difficult miscellaneous diseases, its curative effect obtains affirming of hygiene department already, and product has also passed through relevant expert, professor's formal evaluation.The electrotherapeutic apparatus that output can increase progressively automatically because output can progressively increase in use, thereby has improved curative effect, has also alleviated medical worker's operation simultaneously greatly, firmly gets medical personnel and patient's welcome.
The circuit that Chinese patent GG92107629.0 provides, though realized the purpose of power stepless self-increasing, it also has following not enough:
(1) power tube owing to power amplifier in the circuit is operated in the amplification region, one pipe is undertaken voltage stabilizing and two tasks of impulse waveform modulation simultaneously, obviously somewhat unable to do what one wishes, brought certain influence for the assurance and the realization of performance indications, particularly since therapeutic instrument when clinical use, load patient's impedance is actual to be a underrange that variation is bigger, the state of an illness is more serious, load variations is also bigger in the therapeutic process, because power tube is open loop control, can't follow the tracks of, can not regulate and control, also just reduce this instrument various different patients for patient's self the influence that load variations caused, different sick kinds, the optimum adaptation of the different state of an illness, promptly primary circuit has only overcome the influence of mains supply shakiness to the output of instrument power, and unresolved patient's load when changing to the influence of instrument actual power output.
(2) because power tube is operated in the amplification region, the performance indications of power tube are had relatively high expectations, in the actual production, because the discreteness of power tube performance, the concordance of its voltage regulation performance is just relatively poor, and this has also brought difficulty to components and parts screening and machine debugging.
(3) because the load of power tube is a pulse transformer, it is a bigger inductance element, the variation of base current is being amplified under the duty in the non-pure resistance load, the variation of collector voltage, the dynamic range of following the tracks of variation to the linearity of pulse transformer time utmost point output voltage is narrower, even under big situation, wave distortion also occurred and caused discomfort to patient, the patient who has just required to reduce output in the past not reaching the optimal treatment amount, had also just influenced curative effect.
(4) power that provides of former patent working example is from increasing frequency, be evenly to produce 128 or 256 pulses in the clock time at 30～60 minutes, promptly guarantee in the overall process of patient undergoing treatment 30～60 minutes, the pulse power that patient accepts is even stepless self-increasing, patient is on the maximal therapeutic dose of fever from start to finish, and patient tangible feeling of fatigue occurs after the neutralization treatment of receiving treatment, even the patient who has treatment time not then, promptly say: " being unable to stand " requires shutdown to have a rest.This causes bigger pressure not only for the patient psychologically with on the physiology, and has reduced curative effect.
(5) primary circuit also has a deficiency, because total accent potentiometer of output is set at the secondary of pulse transformer, less to the dynamic range that output is actual adjustable, the patient who has is because responsive especially to electricity irritation, even total potentiometer of transferring is transferred to minimum, it is too big that output is also disliked.Clinically, when treating cerebral palsy to the baby about one-year-old, generation is just arranged, firm start because output can not be started from scratch, is once beaten the patient and has been cried.
(6) at present commercially availablely respectively lead flat instrument, all lack a kind of function of exporting locking.Promptly when patient when receiving treatment, the output of instrument has reached patient's maximum tolerated dose, this moment as power failure for some reason suddenly, instrument quits work, because the doctor is short of hands, fail in time to shut down or reduce and export, waiting for a moment extraneous power supply recovers suddenly, first pulse of sending of instrument, be power output maximum before having a power failure, this is undoubtedly one concerning a body and mind fragility has no thought and the spiritual patient who prepares stimulate greatly and vibrate, if the heart patient may also can cause danger and injury.
In sum, develop a kind of above-mentioned shortcoming and defect that can overcome, high voltage, low-frequency electrotherapeutic apparatus of a new generation are swung in face of us historically.
Purpose of the present invention; a kind of not only power stepless self-increasing will be provided exactly; independent increment is linear; and can be high stability when occurring than great fluctuation process to input civil power and output loading; patient is tireless; have output latch-up protection function, always transfer the potentiometer to open the electrotherapeutic apparatus of new generation of beginning from zero.
Main points of the present invention are in its main circuit, to be provided with adjustable drive circuit.It is made up of big dynamic adjustable mu balanced circuit of high accuracy and switching regulator pulse power amplifier circuit.Being about to adjustable voltage stabilizing and impulse modulation separately carries out.Adjustable mu balanced circuit is formed highly sensitive feedback network by integrated operational amplifier and sample circuit, so precision of voltage regulation height, out-put dynamic range is big; The switching regulator pulse power amplifier circuit is operated on off state with power tube, promptly uses the switching tube modulating pulse, has significantly reduced the influence that load variations causes output, has also improved the concordance of output pulse waveform when total accent potentiometer is adjusted simultaneously.In addition, increased the high threshold comparator that one-level is made up of integrated operational amplifier, improved the capacity of resisting disturbance of system greatly, made instrument have higher reliability at the switch controlled end.
