Description

Direct heating ultrasonic wave far infrared ray therapeutic apparatus

The present invention relates to a kind of physiotherapy table and relate in particular to a kind of electronic therapeutic instrument for the treatment of multiple diseases such as arthralgia.

The present invention adopts directly-heated type ultrasound wave far infrared to produce principle, produce the ultrasound wave far infrared with 20-30KC high frequency alternating current-direct current by the resistance silk and produce stronger infra-red heat and higher eddy current heat indirectly, produce certain magnetic field effect, can make the body affected part strengthen blood circulation, the booster immunization function reduces the sensory nerve irritability, reduces the generative capacity of fibrous connective tissue, raise immunity, thereby multiple disease all had the treatment function.

The field effect therapeutic equipment of Chu Shouing is a kind of 50 all energy of using that directly utilize in the market, three tap switch control voltage height, the health care directly-heated type infrared physiotherapeutic device that can only show three kinds of different temperatures, temperature can not freely be selected between 20 degree-70 degree, the shortcoming of its radiation bag is, adopt significantly in order to improve temperature that the resistance silk of multi-parallel repeats to fold, thereby cause the magnetic field disorder easily, short circuit after the different pole parallel connection, magnetic force is offset, make magnetic field effect weaken with addition after the magnetic pole parallel connection, owing to its direct employing was made the energy in 50 weeks, in the alternation frequency spectrum, belong to extremely low frequency, the heat with medium generation on every side under the effect in low alternating electric field or magnetic field is extremely low, the eddy current heat of low its generation of frequency is also low, so eddy current effect is not remarkable yet.The objective of the invention is to design a kind of power consumption less, easy to use, therapeutic equipments that therapeutic effect is good.

Content of the present invention and circuit structure thereof:

By BG ₆Be that 555 o'clock base 8,7,6 outer feet meet R ₆, R ₁₅, R ₁₆And C ₇Constitute the square wave multivibrator, R ₇, C ₇For moving back the commissure circuit, the 3 feet output termination C of BG6555 ₈, R ₁₆Be preposition amplifier tube BG ₃Following inclined to one side resistance, R ₁₀Be BG ₃Current Negative Three-Point Capacitance resistance, amplifying signal through M * D2000 coupling transformer to SW ₂Adjustable attenuator (temperature controller) is to the attenuation resistance R ₁₄To power tube BG ₄Base stage, straight after it amplifies, hand over recombination current through 100MA */I * 5 ammeters are through Ra, R _b(radiation bag resistance silk) and BG ₉Commutator connect finish mainly shake, buffering, power amplifier series integrated circuit.

By BG ₅Be 555 o'clock bases delay circuit as shown in the figure, adopt R1 blood pressure lowering, BG ₂Rectification, BG ₁Voltage stabilizing, G ₁Voltage about the exportable 10V of filtering is as the alternating voltage of connecting 32.4V, BG ₅, 555 2 feet are high level 3 feet output high level, bidirectional triode thyristor BG ₁₁The admittance that is triggered, this moment, dc source Vcc began the SW that flows through ₁Give capacitor C ₂, C ₃Charging, 3 feet return low level when voltage reaches 2/3Vcc, C ₂, C ₃Discharge controllable silicon BG rapidly through 555 internal discharge pipes ₁₁Turn-off BG ₉The bridge rectifier ac input end opens circuit, and the path radiation bag is blocked in the direct current supply of power tube does not thereupon have thermal source, finishes and delays locking circuit automatically, delays the time limit by SW ₁Control can freely be selected in 10 minutes-3 hours.SW ₆For the hilted broadsword two-throw switch is left a long time, be to the right regularly.

The structure of radiation bag, adopt the resistance silk of 300-600W, dc impedance is 50-100 Europe, be fixed on felt or other fabrics with the arrangement of monolayer zig-zag type zigzag, adjust the circle distance of resistance silk, the also height of scalable temperature, another effect of felt is to keep the temperature of radiation bag not scatter and disappear, this structure can not cause the magnetic field disorder, the compound alternating current-direct current pulsed magnetic field intensity of generation.

The present invention is owing to adopted the higher-order of oscillation supersonic generator of 20-30KC, act on the radiation bag that heater element (resistance silk) is made, not only can produce higher infra-red heat, can also produce stronger eddy current heat, magnetic field effect is preferably also arranged, thereby patient's skin is had stronger permeability.During treatment, directly do not touch skin, 1-5mm also has curative effect preferably at interval, circuit is compared with mechanical controlling timer when having adopted electronics to delay controlling again, and volume is little, does not have hot-tempered sound, overcome in the time of to control 1 hour shortcoming, power consumption is little, maximum power consumption 22W, and temperature 20-70 degree is adjustable, use minimum temperature to be not less than 30 degree, the maximum output of 25KC orthogonal composite pulse electric current 480MA-800MA, the actual pair load currents that use are no more than 500MA, and single load is no more than 300MA.The performance of therapeutic instrument provided by the present invention, it makes the physiotherapeutic instruments of the energy useful 50 weeks as " field effect therapeutic equipment " than current, " Infrared High-Power stove and infrared lamp " etc. have penetrate dark, can directly arrive skin and blood vessel, reduce space loss, so reduced energy resource consumption, its mobility, motility all are better than the Infrared High-Power lamp and the infra-red furnace of use at present, volume is little, in light weight, being easy to carry is fit to family's use, for rheumatic arthritis and rheumatoid arthrosis special curative effect is arranged especially, cooperate massage, acupuncture, medicine of a warm nature therapy effect is better.

The present invention adopts supersonic frequency 20-25KC to act on load radiation heating original paper, the high generation of frequency eddy current heat is also high, temperature is higher, thereby the far-infrared thermal that produces is stronger, have magnetic field effect preferably, thereby multi-parallel is folding significantly to have overcome " field effect instrument " employing resistance silk, the magnetic field disorder that causes, heteropole magnetic short circuit in parallel is offset, and reduces the shortcoming of magnetic effect.Adopt electron temperature-control from 20 degree-70 degree C tunable oscillators, intervalometer all adopts integrated circuit, and intervalometer was from 10 minutes--and arbitrarily adjustable in 3 hours, overcome one hour restriction of mechanical timer.
