Description
Technical field
The present invention relates to a kind of therapeutic instrument, specifically is the therapeutic instrument that the body biological effect of electromagnetic field is regulated in a kind of adjustable low stimulation.
Background technology
For fracture patient; The doctor can beat clamping plate and Gypsum Fibrosum at fracture and carry out the affected part and fix, and facts have proved, applies the magnetic line of force again to the affected part and can play good auxiliary treatment effect; At this moment; The magnetic line of force penetrates patient's fracture site outer clamping plate, Gypsum Fibrosum and medicated clothing and acts on subcutaneous tissue and skeleton, produces a series of biological effect of magnetic field, reaches the therapeutic effect of detumescence, antiinflammatory, analgesia, promotion union of fracture.
Helmholtz coil is that a pair of identical current-carrying circular coil is parallel and coaxial, passes to equidirectional electric current, when coil-span equals coil radius, the total magnetic field of two current-carrying coils near the mid point of axle in a big way in be uniform.Because Helmholtz coil has the uniform characteristics in magnetic field; Therefore people consider Helmholtz coil is used for the treatment of bone wound; But for how using Helmholtz coil to reach how effectively controlling magnetic field is strong and weak, never unification is come to a conclusion, thereby has limited its use.
Summary of the invention
Can not effectively be applied to the problem of bone wound, osteoporosis therapy to Helmholtz coil in the prior art, the present invention provides a kind of therapeutic instrument.
The objective of the invention is to realize through following technical scheme:
The therapeutic instrument of body biological effect of electromagnetic field is regulated in a kind of adjustable low stimulation; It is characterized in that; Comprise Helmholtz coil, the adjustable dc source of voltage, clock circuit and amplifier, the cathode output end of the adjustable dc source of said voltage connects terminals of Helmholtz coil, and another terminals of Helmholtz coil connect the outfan of amplifier; The outfan of clock circuit connects amplifier input terminal, and the earth terminal of amplifier is connected with the negative pole of the adjustable dc source of voltage.
The internal diameter and the external diameter of described Helmholtz coil are respectively 230-260mm, and the number of turn of a coil is 200 circles, copper wire diameter 0.9mm.
Two coil stationary of described Helmholtz coil are provided with support in the bottom of coil outside a cylinder.
The present invention is through the adjustable dc source control of voltage Magnetic Field in Helmholtz Loop intensity, and convenient and swift, control accuracy is high; The parameter of Helmholtz coil is to confirm to draw through a large amount of practices, for promoting union of fracture, treatment osteoporosis all to have good effect.The present invention is simple in structure, and therapeutic effect is good, and safe in utilization, have no side effect.

The specific embodiment
With reference to Fig. 1; The therapeutic instrument of body biological effect of electromagnetic field is regulated in a kind of adjustable low stimulation of the present invention; It comprises Helmholtz coil 1, voltage is adjustable dc source 2, clock circuit 3 and audion 4; Two coil serial or parallel connections of Helmholtz coil 1 connect, and the cathode output end of said voltage is adjustable dc source 2 connects terminals of Helmholtz coil 1, and another terminals of Helmholtz coil 1 connect the colelctor electrode of audion 4; The outfan of clock circuit 3 connects the base stage of audion 4, and the emitter stage of audion 4 connects the cathode output end of the adjustable dc source 2 of voltage.Also available other amplifiers of audion 4 (like composite amplifier or integrated circuit) replace.
The internal coil diameter D1 and the D outer diameter 2 that constitute two annulars of Helmholtz coil 1 are respectively 230-260mm; Wherein the number of turn of the copper cash 11 of each coil is 200 circles; Be wrapped in loop coil folder 12 (insulant) that the cross section is a spill along circumference; The diameter 0.9mm of copper cash 11, two of Helmholtz coil 1 lead-in wires 13 are connected with circuit.Two coils are with several bolt 6 coaxial outer peripheral faces that are fixed on an insulating cylinder 5, and cylinder 5 is interior as area for treatment.The fixing support 7 in the outside, bottom of each Circumferential coils.
The present invention is when work; Voltage is adjustable, and dc source 2 is controlled the break-make of audions 4 through clock circuit 3; Control break-make frequency is 10Hz; The pulse current that produces produces uniform pulsed magnetic field in the zone of (in the cylinder 5) near the axis mid point of two coils of Helmholtz coil 1, the position that human body need be treated is put into this zone and can be treated bone wound and osteoporosis.
Innovation part of the present invention is:
1, other similar inventions are used is civilian alternating current and the fixed frequency that produces, the electromagnetic field of intensity; The adjustable dc source of applied voltage of the present invention produces electromagnetic field intensity stabilization, the frequency adjustable joint through clock circuit control audion break-make during work.
2, unidirectional current of the present invention is 12V to the maximum, has guaranteed the safety of the present invention when using.
3, unidirectional current is compared with alternating current, and the magnetic field that unidirectional current produces is stable, lasting.And the clock circuit that increases can carry out Artificial Control to the frequency of electromagnetic field.
4, the intensity in magnetic field can be controlled through the number of turn that increases Helmholtz coil, and then appearance has solved the treatment difference that the factor because of fat causes.
Above-mentioned embodiment is the protection domain that the exemplary illustration of this patent is not limited it; Those skilled in the art can also carry out the part to it and change; So long as do not exceed the spirit of this patent, all be shown the replacement that is equal to, all within the protection domain of this patent to this patent.
