Description
Technical field
The invention belongs to medical instrument field, especially electrodeless electro-therapeutic apparatus of intermediate frequency is a kind of using electromagnetic induction principle,
The device of electrodeless electro-therapeutic apparatus of intermediate frequency.
Background technique
Electro-therapeutic apparatus of intermediate frequency is that the alternating current that the general frequency of one kind is 1kHz-100kHz carries out physiotherapy, health to human body
Multiple method.Medium frequency electrotherapy is to inject electric current of intermediate frequency to subcutaneous tissue, mainly by human skin with more than two electrodes
There are constant amplitude electrotherapy, low frequency modulations medium frequency electrotherapy and interferential current therapy.
Electrotherapy is widely used in rehabilitation department, the department of physiotherapy, mainly has analgesic activity, expansion blood vessel, promotes blood
Ringing, antiinflammation.In addition there are softening scars, adhesion of loosening effect.Furthermore electric current of intermediate frequency can be with excitor nerve flesh
Meat tissue, stimulation nerve generate action potential, and excitor nerve muscle generates contraction of muscle.
But existing electrotherapy is needed through conductive electrode, directly and skin contact, could be input to electric current of intermediate frequency
Inside of human body.The cuticula resistance of skin is big, and electric current is hindered to enter human body.When electrode is installed, in order to reduce skin and electrode it
Between contact resistance, be often required to polishing skin or with conduction liquid impregnate sponge foam electrode after be fixed on skin surface.Treatment
It is troublesome in poeration time-consuming.
The electrode of electrotherapy directly contacts human skin and is related to the biocompatibility of electrode, easily causes skin allergy,
Cause electrochemical reaction, rubefaction, electric current is excessive can also to be burnt skin, cause malpractice.
The electrode of electro-therapeutic apparatus of intermediate frequency is all non-disposable electrode, and disinfection is difficult, contact skin easily cause skin allergy or
The iatrogenic accident such as cross-infection.
The output electrode of electrotherapy has 2 or more, and electric current is led to by entering tissue after electrode and skin contact
It crosses other electrode and returns to equipment composition circuit, since skin resistance is big in circuit, voltage drop is big, and consumption power is big, skin
Sensory fibre is more, can be there is the neurostimulating pain of needle pricked by overstimulation, and treatment lacks comfort.
Since electrode will directly contact skin, direct exposed skin, usually to undress solves trousers, cause treatment not
Just, especially winter can also suffer from cold flu.
Electrode, which cannot be placed, at the position that skin is had damage or is infected limits the use of electrotherapy.
In addition commercial electro-therapeutic apparatus of intermediate frequency is all using alternating current as equipment power supply, if equipment dampness or failure electric leakage are also
Sometimes the danger of hospitalized patients electric shock.
The present invention is directed to develop a kind of electrodeless electrotherapy technology, electromagnetic coupling, electromagnetic conversion and electromagnetism sense are utilized
The principle answered, use is physically-isolated, electrotherapy mode without electrode, avoids above-mentioned electrotherapy and is exported using electrode
Disadvantage.
Summary of the invention
In view of the shortcomings of the prior art, the present invention relates to a kind of electrodeless electrotherapy technology, electromagnetic coupling, electricity are utilized
The principle of magnetic conversion and electromagnetic induction, use is physically-isolated, electrotherapy mode without electrode, avoids above-mentioned medium frequency electric
Treat the disadvantage using electrode output.
Medium frequency electrotherapy uses frequency for the medium frequency sinusoidal current of 1~100kHz.Clinically conventional frequency is 2~5kHz,
Common method has uniform amplitude medium frequency sinusoidal electrotherapy, amplitude modulation intermediate frequency sinusoidal current therapy and three kinds of interferential current therapy.Frequency of modulated wave is
10~200Hz can be used all-wave or half-wave, continuous modulation or interruption modulation, persistent wave also can be used and modulating wave is alternately present,
Or the modulating wave of frequency alternation.Modulating frequency current has the characteristics of low, electric current of intermediate frequency concurrently, for relieving pain or promoting blood circulation,
It is obvious that effect is used alone in lower, medium frequency electric；When for neuromuscular stimulation, since skin irritation is small, patient can tolerate larger
Electricity.Interference electricity is the constant amplitude medium frequency sinusoidal current (the multi-purpose 5 ± 0.1kHz of clinic) using two groups of 0~100Hz of frequency phase-difference, is handed over
The fork input same position of human body.Electric interfering field is formed in cross part, 0 is generated by the beat principle of sinusoidal electric wave in vivo~
The low-frequency modulated mid-frequency electric stimulation of 100Hz.3 groups of constant amplitude medium frequency sinusoidal currents are clinically utilized, intersect input human body from three-dimensional space,
Three-dimensional electric interfering field is formed, effect is better than general electric interfering field.After improved, using the sine electricity of 3 groups of intensity alternate changes
Stream, makes local stimulation be easier to endure for patient, further increases therapeutic effect, and the method is known as dynamic solid interference electricity
Therapy.It clinically commonly uses electric current of intermediate frequency and treats soft tissue injury, neuritis, dysmenorrhea, circulation obstruction of limbs, peripheral nerve injury is drawn
The muscular paralysis risen, stomach and intestine and smooth muscle of bladder inability etc..The person that suffers from acute suppurative inflammation, pregnant woman, thrombophlebitis patient,
Pacemaker person disabling.
The present invention utilizes electromagnetic coupling, the principle of electromagnetic conversion and electromagnetic induction, and use is physically-isolated, without electrode
Electrotherapy mode avoids above-mentioned electrotherapy and uses the disadvantage of electrode output, and can achieve the effect that electrotherapy.
In order to achieve the above objectives, the technical solution of the invention is as follows:
In order not to achieve the purpose that electrotherapy again with electrode, the present invention is former using transformer sample electromagnetic conversion and electromagnetic induction
Reason drives a coil with electrotherapy pulsating current, this coil is equivalent to the primary of transformer, the intracorporal tissue of people due to
The conductive secondary that can be similar to transformer, the variation of primary current can cause to generate induced electricity in secondary human body
The variation of stream, to achieve the purpose that electrodeless electrotherapy.
The output winding of electro-therapeutic apparatus of intermediate frequency can be not directly contacted with human body, and alternating magnetic field is generated around coil, and magnetic field can
Clothes, skin are passed through with without hindrance, reaches subcutaneous and organization internal output electric current of intermediate frequency.
In order to reach the technical indicator of electrotherapy, use semiconductor switch device with the basic intermediate frequency of 1KHz-3KHz just
Profound wave electric current, with the mode that the low frequency modulations of 1Hz-100Hz and amplitude are modulated realize common intermediate frequency electro-therapeutic apparatus technical parameter and
Clinical treatment function.
The technical program is overcome with completely new thinking, removes the electrotherapy traditional mode and electrode for using electrode therapy
