Description
Technical field
The present invention relates to a kind of medical health equipment, particularly a kind of low frequency electric therapeutic instrument.
Background technology
In every organism with life, the capital has a kind of electric current of uniqueness, certainly, human no exception, self imperceptible very faint low-frequency current all can be sent in intravital each positions of body such as human heart, brain, muscle, nerve, and this is called " bioelectric current " by biologists.Bioelectric current plays important effect to the normal performance of physical function, and especially the coordinated operation to aspects such as the cell in the human body, neural meridians has great importance especially.
Modern scientific research confirms, human body approximately is made up of 60,000,000 cells, and all there is cell membrane potential in each tranquillization living cells, and cell is under the effect of transmembrane potential, sodium ion around making, potassium ion, chloride ion form arrangement of gradients, and carry out metabolic activity by ionic exchange.The human life activity should keep certain potential balance under various situation, when human body had pathological changes, human inner cell's current potential was just uneven.
Chinese medicine is particular about the QI and blood circulation, meridians are unobstructed, " pain is then obstructed, and general rule is not bitterly " that traditional Chinese medical science back warp is often mentioned, essence is meant meridians, meridians play the effect of coordinating the internal and external equilibrium negative and positive under human body normal physiological situation, defend outer function in the performance battalion.And modern scientific research confirms: if the function of meeting the tendency of meridians is subjected to the influence of exopathogenic factor and causes obstructed, the intravital QI-blood circulation of people also can be obstructed so, and QI and blood is referred to as human body it " electric ", it is the human-body biological electric current, also be that the intravital bioelectric current of people is obstructed,, can cause that resistance increases, electric current is obstructed if the neurocyte current potential of same human body is unbalance, electrical signal transfer is obstructed, and also can cause the slight illness of related neural and linked groups.And meridians are response systems that disease is presented on body surface or subcutaneous tissue, it through the cave reflecting point on the meridians, can make cell potential recover normal so on certain reflecting point, pass to electric current, get through electric current, make patient's meridians unimpeded in moment, make it to reach the purpose of " general rule is not bitterly ", so can reach dredge the meridian passage, the miraculous effects of slight illness are invigorated blood circulation, eliminated in ventilation.People can adopt the function of current the locating through the cave on human body of certain frequency, particularly identical with the bioelectric current frequency of human body self electric current is adjusted the intravital bioelectric current of people, make it obtain balance, and repair neurocyte current potential, reduce resistance, keep neural electric current unobstructed, electroneurographic signal is transmitted smooth, reaches the purpose of the rehabilitation that promotes linked groups's slight illness.According to above principle and purpose, people have invented electric therapeutic instrument.
At present, people make and traditional electric therapeutic instrument of use all is to adopt the mode (branches of existing low-frequency therapy apparatus, mid-frequency treatment device and high frequency treatment instrument such as frequency conversion, pulse, waveform has triangular wave, square wave, trapezoidal wave, sine wave, staircase waveform, exponential wave etc.), earlier 220V alternating current (or directly adopting direct current) reuse electronic technology after the voltage stabilizing of potential device step-down rectifier becomes direct current is carried out the frequency conversion output of boosting again and act on human body with electrode, be the little electric current of high-frequency and high-voltage, mostly be direct impulse.As in China's disclosed patent application on January 12 in 2005: electronic therapy instrument for digital acupoint pressure on channels and collaterals (application number 200410031189.7) has been introduced a kind of high frequency treatment instrument of being made up of shape wave producer, amplifier, high-frequency output transformer, Output Display Unit, shape wave controller fast, provides power supply by two-windingtransformer to this quick electronic therapy instrument for digital acupoint pressure on channels and collaterals.Show through the brainstrust survey, the intravital current waveform of people is the pure sinusoidal little electric current of low frequency low-voltage, and the treatment electric current that this quick electronic therapy instrument for digital acupoint pressure on channels and collaterals provides to human body is the high voltage micro-current of high frequency, be not inconsistent with the pure low frequency low-voltage sinusoidal current of self in the human body, use for a long time, can make human body produce some bad reactions.In China's disclosed patent application on June 11 in 2003: introduced a kind of low-frequency therapy apparatus that is made of intelligent controller, charge pump and polarity control circuit in the low-frequency therapy apparatus (application number 01139781.0), this low-frequency therapy apparatus can adopt battery to be used as the power supply of low-frequency therapy apparatus.Though this low-frequency therapy apparatus can provide the treatment electric current with the low frequency sinusoidal current close frequencies of human body, but be provided with complicated electric elements such as intelligent controller, charge pump and polarity control circuit in this low-frequency therapy apparatus, dc source is given birth to processing frequently, common people are not easy operation, and damage than being easier to, damage the back and be difficult for problems such as repairing.
Summary of the invention
