Description

Freq-variable electronic weight-lossing machine

The present invention relates to a kind of new-type electric pulse therapeutic equipment, exactly be a kind of frequency conversion type low frequency pulse therapeutic equipment that is used to lose weight.

Along with low frequency pulse therapeutic equipment in clinical medical extensive use, its treatment mechanism and effect are admitted by the public, thereby low frequency pulse therapeutic equipment development in recent years is very fast, the instrument of treatment fat-reducing usefulness is wherein a kind of.In the structure of this quasi-instrument; generally include a low-frequency pulse producer; its generation has the impulse wave of therapeutic effect; also include a power amplifier in order to amplify the treatment pulse; usually also have an output regulating circuitry and supporting output electrode in the structure; treatment pulse through regulating is added on patient's the therapentic part by electrode, thereby reaches certain therapeutic effect.By secular clinical observation invention, under certain characteristic frequency, produce the adaptability of human body through long impulse stimulation meeting, directly have influence on therapeutic effect, for this reason, centering, low-frequency pulse therapy machine improve in the prior art, in overall structure, increase converter and ON-OFF control circuit at random, utilized the stochastic signal that produces to change the frequency of treatment pulse signal, thereby formed the pulse therapeutic device of frequency conversion type.For example, " CN88203460 " of the Decree of Patent Office of China, " CN87101354 ", " CN88206161 " come from this basic design.Its basic structure is for producing the stochastic signal of similar white noise, thereby and carries out processing and amplifying based on this and produce a frequency, all changed randomly treatment pulse of multiple parameters such as amplitude, dutycycle.Yet, also be provided with at the electronic pulse therapeutic machine that is used for weight reducing treatments and take similar design thought, referring to Chinese patent " CN87210202 " " CN88215017 ".Its main cause is that the basic mechanism of weight reducing treatments is not quite similar with general electric pulse acupuncture therapeutic instrument.The general treatment instrument is to adjust unbalanced physiological status by excitement relevant muscle and nervous system, and the traditional Chinese medical science then thinks to dredge relevant meridians, is main criterion to stimulate the excitement levels that produces.And electron slimming machine mainly utilizes the alternating impulse that is produced to cause the polarity conversion of adipose cell, and generation consumes, and finally reaches the purpose of subduing fat.So the treatment pulse of its generation should have constant relatively frequency range, produce resonance to guarantee the conversion of its electricity irritation and molecular polarity, thereby reach best action effect.The frequency of just treating pulse can not immoderate change at random.Can only on the certain limit basis, apply frequency-conversion processing,, prevent to subdue therapeutic effect because of the adaptability of muscle nerve to strengthen therapeutic effect.

The purpose of this invention is to provide the new design of a frequency conversion type pulsed electron weight reducing apparatus, it can keep the low-frequency pulse basic parameter of high curative effect, has tangible frequency conversion effect again, overcomes the adaptability that patient's human body produces because of long-term treatment.

Basic design of the present invention is: keep the low-frequency pulse device that produces therapeutic effect, power amplification circuit, on the basis of adjustable output circuit and output electrode, increase an improved converter at random and one by deciding the on-off circuit that pulsewidth unidirectional pulse generator is formed.Remove the trigger switch circuit by the triggering signal at random that converter sends, touch at every turn and then produce a 0.5-1.5 pulsewidth second unidirectional pulse signal, deliver to the control utmost point of low-frequency pulse producer, control low-frequency pulse producer work during this signal high potential, export a string effective treatment pulse, through power amplifier and adjustable output circuit, be applied to patient's fat place by electrode.Because each triggering signal interval randomness, thus also change at random of the time that every group of effective impulse sent, thus overcome patient's adaptability, also just guaranteed every group of high effect of treatment pulse simultaneously.

Come from above basic design, key of the present invention is the converter at random that designs, is actually the random signal generator of the random variation of an interval.On-off circuit then is one and decides pulsewidth unidirectional pulse generator.Converter is by a sawtooth generator at random, voltage converting frequency and frequency counter three parts are formed, deliver to the voltage ratio of voltage converting frequency than input by the voltage signal that sawtooth generator produces, be converted to the pulse signal that a frequency accidental changes through voltage to frequency converter, the pulse signal that the frequency accidental of being exported by voltage converting frequency changes exports in the frequency counter as count pulse.Frequency counter is return-to-zero when counting down to definite value, export a triggering signal simultaneously, thereby the trigger impulse that frequency variation signal is treated to an interval change at random is delivered to the trigger electrode of on-off circuit, behind the circuits for triggering switch, produce a Fixed width pulse control signal by it and deliver to low-frequency pulse producer, the persistent period of the treatment signal that is sent, the interval of two subpulses then depended on the stochastic behaviour of converter fully by the pulse width decision of on-off circuit.Thereby can realize purpose of the present invention.

Further specify below in conjunction with accompanying drawing and the objective of the invention is how to realize.

As can be seen, the unidirectional pulse generator of forming on-off circuit 2 can adopt 1/2 556 slice, thin piece and resistance R in the electrical schematic diagram that is provided by embodiment ₁₁, R ₁₂, capacitor C ₁₀, C ₁₁With diode D ₂Be barricaded as, pass through capacitor C from the triggering signal of converter at random ₉Be connected to 556 the 6th foot, the control that adds to low-frequency pulse producer from the control impuls of the 5th foot output is extremely gone up.

The treatment with low-frequency pulse producer 3 in Fig. 2 by a CD ₄₀₁₁Slice, thin piece and resistance R ₁₃, capacitor C ₁₂Overlap joint is connected to CD from the Fixed width unidirectional pulse of on-off circuit circuit ₄₀₁₁The 1st foot on, circuit starting of oscillation when pulse is positive potential is the bi-directional symmetrical square wave by the 4th foot output treatment pulse, to reduce the polarization damage that the unidirectional square wave of electron slimming machine in the past causes when the treatment.Its effective therapeutic frequency is chosen as 10-50Hz, and this treatment pulse signal passes through R ₁₄Add on the base stage of power amplification circuit 4.Power amplification circuit 4 adopts a compound transistor amplifying circuit (BG in an embodiment ₂, BG ₃), its primary coil with transformator T is load, and the marginal coil of transformator and adjustable resistance W combine output regulating circuitry 5, and by the power output that can select the adjustment of W to adapt, again by electrode P with the patient ₁, P ₂To effectively treat pulse and be applied to the lipotrophic position of patient, can reach satisfactory therapeutic effects.

Following mask body is discussed the design improvement of converter 1 at random.Converter at random among the present invention does not resemble the prior art generator as the treatment pulse, come down to a frequency variation signal generator, provide a specific design of converter among Fig. 2, the sawtooth generator 1A of converter is by 1/2 556 slice, thin piece and resistance R among the figure ₀, R ₁, R ₂, capacitor C ₁, C ₂, C ₃Be barricaded as, at C ₃Upward form a voltage by changing between the 0.3-8 volt, rising edge 12-15 second, the zig-zag of trailing edge 7-8 second number, this signal is through audion BG ₁Behind the emitter follower stable operating voltage of forming sawtooth waveforms is delivered to the input of voltage translator circuit 1B.

Electric pressure converter 1B adopts LM in an embodiment of the present invention ₃₃₁Slice, thin piece and resistance R ₅, R ₆, R ₇, R ₈, capacitor C ₄, C ₆Overlap joint.From the emitter follower output voltage signal by resistance-capacitance coupling (R ₄, C ₅) cause LM ₃₃₃₁The 7th foot, through LM ₃₃₁Voltage/frequency is converted into the pulse counting signal of frequency conversion at random and delivers to frequency counter 1C.In order to be illustrated more clearly in the effect of this part circuit, the LM that provides in conjunction with Fig. 3 ₃₃₁The circuit reduction schematic diagram is further explained.

As can be seen from Figure 3 be in a ratio of when big when the sawtooth voltage that is added to the 7th foot and the 6th foot voltage, then comparison amplifier K ₂Start pulse intervalometer K ₃, while intervalometer K ₃Open frequency output and switch connection current source K ₁, cycle t=1.1R ₇C ₆Current source K in this cycle ₁With electric current 1 to capacitor C ₄Charging, charging charge is Q=1t, and the charging result makes the 6th foot voltage be higher than the 7th foot, and 1 interrupts intervalometer K when this end cycle ₃Automatically reset capacitor C ₄Pass through resistance R ₄, R ₅Discharge starts pulse intervalometer K once more when the 6th foot equates with the 7th foot voltage ₃, then begin another circulation.So output frequency number just depends on the 7th foot voltage Vln, R ₅, R ₆, R ₇, R ₉, C ₄Thereby (concrete mode is with reference to LM to finish frequency inverted ₃₃₁Illustrate).Because each pulse intervalometer K that starts ₃The time Vln depend on the instantaneous value of sawtooth voltage at that time fully, thereby form the stochastic behaviour of f.

From frequency converter 1B output be successive, but the pulse signal that frequency accidental changes is only used the also uncontrollable low-frequency pulse producer of this signal, this signal is sent into frequency counter 1C.Frequency counter 1C is a CD among the embodiment ₄₀₂₀Slice, thin piece and resistance R ₉, R ₁₀, capacitor C ₇, C ₈, diode D ₁Be barricaded as, pass through capacitor C from voltage converting frequency 1B variable-frequency pulse ₇Input to 4020 the 7th foot as count signal, when count value reached rated value, frequency counter promptly sent a trigger impulse.Since from frequency changer 1B be the pulse signal of frequency conversion at random, so the interval of the trigger impulse of sending out has also formed very strong randomness, this random pulses triggering signal is delivered to the trigger electrode of on-off circuit 2, thus formation switch time randomness.

In sum, trigger the output all cause a string treatment pulse each time, the time that every group pulse is sent is again change at random, then form good stochastic behaviour, and kept and treat pulse parameter efficiently.
