The person's character of light is a photon, and photon is represented luminous energy.Laser photon is represented laser light energy.Laser photon has four big effects: i.e. heat effect, galvanomagnetic-effect, pressure effect and actinic effect.The photon wave spectrum scope that wherein causes actinic effect is the nearultraviolet rays and the visible light of 350～700 nanometers normally, and the wavelength of He-Ne Lasers photon is 632.8 nanometers, glows can produce actinic effect.The super beginning that human eye produces the vision conduction partly is amphiblestroid cone cell and looks very thin born of the same parents, and the cone cell that is in macular area is the most responsive part of central vision.The He-Ne Lasers photon wavelength is 632.8 nanometers, glows, and is the most responsive wavelength of pyramidal cell.Therefore, utilize He-Ne Lasers photon irradiation macular area, can cause the activity of retina cone cell, can effectively improve the local microcirculation and the metabolism of macular area.Photon self control amblyopia instrument of the present invention utilizes the heat effect and the actinic effect of He-Ne Lasers photon exactly, and the excitation optic nerve promotes it to grow, and reaches the purpose of treatment children amblyopia.
Photon self control therapeutic instrument for amblyopia of the present invention is compared with automatic frequency conversion laser therapeutic apparatus for amblyopia, and circuit theory still is that machine construction is all different fully, the following advantage of tool of the present invention:
1, it is more safer than light beam diaphragm system that light beam cuts off system.Automatic frequency conversion laser therapeutic apparatus for amblyopia, what the processing of light beam was adopted is two frequency multiplication dark slide systems, laser beam can only change the density of light beam, and continuous light beam is not processed into interrupted light beam by after this system handles.Be not easy to guarantee with such continuous light beam irradiation eyeball safety.Photon self control therapeutic instrument for amblyopia of the present invention, what adopt is cylinder open-work light beam chopping up apparatus, can be divided into interrupted light beam to continuous light beam, greatly reduce time of exposure like this, even motor is in minimum speed (2 revolutions per seconds), the time of exposure of light beam is also less than 0.04 second each time, thereby is perfectly safe.The flicker hot spot that constantly changes more has incentive to cone cell simultaneously, and activation effect is better.
2, motor-drive circuit is more advanced.By clinical verification, when motor is in low-grade rotating speed, should reduce its rotating speed as far as possible, can strengthen the amplitude of variation of photon flicker like this, strengthen incentive action, thereby improve its therapeutic effect optic nerve.Automatic frequency conversion laser therapeutic apparatus for amblyopia control motor speed is realized by changing driving voltage.This control method has apparent in view shortcoming.Because motor has magnetic hysteresis, uncontrollable its rotating speed when the slow-speed of revolution.Therefore this machine motor deep low gear rotating speed only accomplishes that per second 7.5 changes.What photon amblyopia therapeutic equipment of the present invention adopted is brand-new drive circuit.Control motor speed by changing dutycycle rather than changing voltage, can avoid the influence of magnetic hysteresis, motor speed can be done very lowly, minimumly accomplishes 2 revolutions per seconds.Compare the amplitude of variation that photon self control therapeutic instrument for amblyopia of the present invention has strengthened the photon flicker with the automatic frequency-conversion amblyopia therapeutic equipment, can increase the effectiveness of treatment.
3, increased final stage hot spot blood processor.Automatic frequency conversion laser therapeutic apparatus for amblyopia from the light beam of diaphragm system output, is not handled again, and the size of light beam is fixed (20mm).Photon amblyopia therapeutic equipment of the present invention is provided with a hot spot adjusting device of being made up of biconvex mirror after light beam cuts off system.By regulating two distances between the convex lens, promptly the size of scalable hot spot can be regulated (measuring apart from 2 meters of laser photon launch point) usually between 30～50mm.Hot spot by the output of hot spot regulating system has two outstanding advantages: the one, because hot spot is enough big, can shine patient's full eye and acupuncture point on every side, as behind fair, Sibai, the ball, chengqi, Zanzhu etc., make it produce the laser accunputure effect, dredging the meridian thus, the function of nervous system regulation is improved the blood circulation of eyes, improves therapeutic effect; Because hot spot enlarges, the photonic power density on the unit are reduces greatly, is about 0.6mw/cm simultaneously
2Below, satisfied safety requirements greatly.
