Description

Eight Diagrams recovery therapeutic instrument

The present invention relates to a kind of massaging and physiotherapeutical instrument, especially for cervical spondylosis, lumbar spondylosis, a kind of Eight Diagrams recovery therapeutic instrument of scapulohumeral periarthritis rheumatism, extremities joint pain and the treatment of exercise-induced muscular acute and chronic ligament injury.

Existing massaging and physiotherapeutical instrument has multiple, disclose as Chinese patent literature 90100102.3 and a kind ofly can simulate the electric pulse channels and collaterals therapeutic instrument that the manual massage treats the human body slight illness, it is by signal generator, blocking oscillator, functional select switch, channel to channel adapter, power amplifier, intermediate frequency or low frequency follower, electronic circuits such as occupancy controller are formed, its output waveform has: discontinuous wave, dilatational wave, push wave, take ripple, frequency conversion amplitude-modulated wave, output signal frequency that intermediate frequency (1600～500 (Hz) or low frequency (1000Hz is following) are arranged.It is characterized in that: the therapeutic instrument electronic circuit also includes (variable) frequency converter and amplitude modulator, the low and medium frequency permutator, employing is modulated by another group frequency of oscillation one group of built-in oscillation frequency, and with its be transformed into automatically another the group waveform be subjected on the triangular modulation output amplitude, produce the amplitude-modulated wave frequently that modifies tone thus, to push wave with by crossing the application automatic conversion technology, the massage ripple of forming specific function, whole therapeutic process is such: signal generator is subjected to its pulse signal that has the cycle to change of occupancy controller control output to arrive channel to channel adapter through functional select switch, be input to power amplifier, through power amplifier, export from follower, during the frequency parameter of blocking oscillator is subjected to, the control of low frequency permutator is in the realization, the translation function of low frequency frequency signal output, its output current can reach 30mA.The electric pulse that this device produces is applied to has on the tissue that sense is played in intensive suction and the sense of massaging.Weak point is, the circuit of recommendation is also complicated, haves much room for improvement, and the simulation manual massage's who is produced effect is also undesirable.Chinese patent literature 91106178.9 disclosed " therapeutic instrument for dysfunction of extremities " for another example, its basic structure is, by probe, main frame and display three parts are formed, probe has four rapiers, be fixed on the probe holder middle part by screw respectively, spring and motion bar are equipped with in rapier inside, be with the mushroom-shaped conductive rubber block on the motion bar, probe holder is connected by hinge with the probe lower limb, one end of lead and four rapiers other end that joins joins through plug and main frame output socket, main frame is made up of low-frequency pulse circuit and control circuit and display three parts, the gauge outfit indicator is arranged on the machine shell panel, beacon lamp, on and off switch, frequency is adjusted knob, the voltage indicator cock, this device is easy and simple to handle, and structure is complicated.Be mainly used in the diseases such as hemiplegia that treatment is caused by cerebrovascular accident.Do not mention the arthralgic disease that to treat scapulohumeral periarthritis one class in the literary composition.Therefore, still can not satisfy the patient's of this class disease of treatment demand.

Purpose of the present invention is exactly at the deficiencies in the prior art, proposes a kind of Eight Diagrams recovery therapeutic instrument, and it is a kind of with the instrument of electricity irritation as treatment means, is mainly used in arthralgic diseases such as treatment cervical spondylosis and scapulohumeral periarthritis.

The present invention is achieved in that and the present invention includes dc source, audio oscillator, pulse generator, power output circuit, display part, output probe, ultralow-frequency oscillator, voltage regulator, timing means.Ultralow-frequency oscillator links to each other with audio oscillator, display respectively, pulse generator respectively with voltage regulator, audio oscillator, power output circuit join.Timing means comprises intervalometer, buzzer and reset switch, reset switch and intervalometer connect, intervalometer and buzzer connect, ultralow-frequency oscillator is the Wien-bridge oscillator that adopts operational amplifier and peripheral cell thereof to constitute, its frequency of oscillation≤0.3Hz, audio oscillator is the multivibrator that is made of an integrated package and peripheral cell thereof, frequency of oscillation is between 20-35Hz, the waveform triangular wave that is as the criterion, its variation is controlled by ultralow-frequency oscillator the same period, and the charging current of the electric capacity of this audio oscillator is controlled by a mirror-image constant flow source.The frequency of pulse generator is at 1300 ± 50Hz.Intervalometer adopts the timer counter agitator.

Operation principle of the present invention is, spike train by the pulse generator generation, be subjected to the modulation of the frequency of ultralow-frequency oscillator and audio oscillator, obtain the spike train of the regular variation of pulse width, simultaneously, because audio oscillator is controlled by the amplitude of ultralow-frequency oscillator, audio oscillator is exported the accurate triangular wave of frequency sweep of Hz more than 20～30 like this, frequency sweep cycle is in 3～4 seconds, the spike train of this regular variation, the spike train that reuse comes modulation pulse generator to produce, thereby the spike train width is modulated, and to have a frequency spectrum wide and become, and intrasonic is arranged, low frequency and IF-FRE component meet electric impulse signal by mount request, this electric impulse signal passes to the patient's body position by the output probe, makes it obtain good massage effect.

Advantage of the present invention is, simple in structure, reasonable in design, the integrated level height of circuit, power consumption is little, the efficient height, the present invention takes pulse frequency to fix and pulse width variation, and modulation signal is a ultra-low frequency signal, make sensation that the spike train of output can produce to the people and can reach different effect of stimulation, output hour has slight not too fast the beating of shallow-layer small muscle group, exports the vibration that degree of depth muscle and meridians are arranged when big, the muscular flaccidity that can make stiff like this, make the muscle that is difficult for movable position and be organized in the stimulation and taken exercise, reach excellent curative, be specially adapted to lumbar vertebra, cervical vertebra, the patient's of diseases such as scapulohumeral periarthritis treatment and rehabilitation massage.
