Abstract
The invention discloses a gallium arsenide semiconductor laser myopia and weak sight therapeutic equipment utilizing magnetic force and movable far figure, which comprises a pair of gallium arsenide semiconductor laser magnetic force treatment far-sight eyeglasses, a N or S magnetic pole absorber and a main unit for adjusting laser energy density, frequency and electromagnetic field Gauss intensity. The gallium arsenide weak laser has the functions of visual stimulus, physical therapy, relaxing ciliary muscle and alleviating visual fatigue, and the electromagnetic field can compress the eyeball so as to shorten the eye pole axis.
Description
The present invention relates to a kind ofly utilize electromagnetic field, solid to look far into the distance the picture figure laser to look and stimulate and the method treatment adolescent myopia of thermal therapy and the ophthalmic medical instrument of amblyopia.The main frame that it looks far into the distance glasses, N or S magnetic pole adsorber and harmony laser energy density, frequency and electromagnetic field Gauss field intensity by gallium arsenide semiconductor laser magnetic force treatment totally three parts is formed.Principle is: 1. the GaAs weak laser has visual stimulus activation, thermal therapy, loosens ciliary muscle and alleviating asthenopia physiotherapy function.The circulation of acceleration ocular blood can make the macula retinae district obtain effective stimulus and make the hemocyte in the retinal vessel increase energy and take oxygen activity, strengthened the passive oxygen supply of retinal neurons and accepted oxygen and the ability of nutrient substance, neither damaged three grades of neurons of retina and have safety again
[5-6]2. the utmost point shortened axis oculi before and after this instrument utilized the electromagnetic field effect oppression eyeball that the N utmost point and the S utmost point inhale mutually, and opposing is because ciliary muscle and the reverse tractive of abducens make the axis oculi lengthening produce the biological effect of myopia.Utilize the long-time opposite pole of electromagnetic field to inhale the principle oppression eyeball front and back utmost point mutually axis oculi is shortened, reach the purpose of treatment myopia.3. laser is warm can produce the biophysics massage effect to eyes with the ophthalmic biological effect of electromagnetic field, and can make eyelash shape flesh reach the biological effect that physical therapy is loosened.4. light source is quasiconductor weak laser source, it does not belong to diverging light, it is characterized in that illumination brightness height, high directivity, the coherence is good, HONGGUANG monochromaticity is pure, specific gallium arsenide semiconductor weak laser is looked the retinal ganglial cells that can make illuminated eye when stimulating and is produced the physiological excitement, optic nerve conduction and lateral geniculate body and visual centre look cortex 17,18 and 19 district's neurons produce the visual system of neural biophysics excited on the threshold value and physiologic character variation activation amblyopia eye, can effectively improve visual information and strengthen the sensitivity of vision excitement, thereby reach the purpose of effective treatment amblyopia to the speed of maincenter conduction and the irritability threshold value of reduction visual system.5. utilize gallium arsenide semiconductor laser magnetic force treatment to look far into the distance the colour of glasses lens barrel inwall or the black and white interval line is gradually far away, square is gradually little and thereby psychology such as spiral and biophysics's method reach eyes and seemingly look the visual effect of infinity object and loosen the ophthalmic ciliary muscle and remove the effect that the spasm of accommodation, alleviating asthenopia and the psychological physic mode of eyes are massaged ciliary muscle.
Mostly therapeutic instrument for shortsightedness on the market is to cause the excessive spasm of accommodation contraction of ciliary muscle to produce asthenopia and make it to occur loose phenomenon to move a trouble eye focus at present, the modern times thing physics research that looks unfamiliar shows that it is tractive eyeball scleral walls forward that the contraction of ciliary muscle is made a concerted effort, and the eyeball of the tractive backward scleral walls effect of abducens causes axis oculi to elongate to increase the weight of myopia in addition.At present amblyopia treatment instrument on the market all be by light emitting diode disperse light source as red green utilize common nothing or coloured light source of dispersing as looking stimulus, yet find to confirm that according to modern vision biophysics and physiologic theory and our experimental result visual system is just insensitive to diverging light
[1-4], the method can not make visual system produce excitatory stimulation on the effective threshold value, more can not make visual centre produce suprathreshold excitation, does not promptly reach the therapeutic purposes that activate visual system, the bad or basic inefficacy of curative effect.
Patent of the present invention is from having abandoned present traditional treatment means in essence, according to the modern neural biophysics and the physiology of visual system
[1-6]The characteristics design, innovative point: but the electromagnetic pole N that around the gallium arsenide semiconductor laser of harmony energy density and frequency myopia eyeglass for weak eyesight, applies and apply electromagnetic pole S suffering from eye temporo side temple (on the spectacle frame), shorten the biophysics effect of axis oculi and utilize gallium arsenide semiconductor laser magnetic force to treat colour or the black and white interval line of looking far into the distance glasses lens barrel inwall gradually far away because the action of a magnetic field that attracts each other of the N utmost point and the S utmost point produces to the compressing of the diameter of axle before and after the eyeball, thereby psychology such as the gradually little and spiral of square and biophysics's method reach eyes and seemingly look the visual effect of infinity object and loosen the spasm of accommodation that the ophthalmic ciliary muscle is removed eyes, alleviating asthenopia and psychological physic mode are massaged the effect of ciliary muscle, thereby reach the biological effect of antagonism and treatment myopia, also rescued amblyopia simultaneously.This instrument volume carries for a short time with easy and simple to handle, but is furnished with the transformator AC/DC.Be applicable to that hospital ophthalmologies at different levels and family use, curative effect is accurate, stable and reliable for performance, safe and practical.Magnetic force is looked far into the distance the simple and clear accompanying drawing 1-2 explanation of figure gallium arsenide laser amblyopia therapeutic equipment: 1, convex lens group; 2, fixed lens barrel; 3, psychological physic picture far away and rotating image inserted sheet folder are looked in convertible interesting rotation; 4, gallium arsenide semiconductor lasing light emitter; 5, gallium arsenide semiconductor laser energy density and pulse frequency actuator; 6, light source machine chamber; 7,3 ~ 6 volts of small machines; 8, therapeutic instrument for shortsightedness adjustable support; 9, travelling gear; 10, power supply and transformator; 11, permanent magnet (the N-S utmost point); 12, music insert earphone; 13 myopia and amblyopia eye treatment window; 14, insert earphone carriage;
