Description
(1) technical field
The invention provides a kind of light brush revolving gear of amblyopia therapeutic equipment, it is the medical treatment device for the treatment of ophthalmic diseasess such as children's myopia using stravismus, specifically, relate to change the medical device technology device of the light-emitting component of function picture, so that the patient carries out the training of multiple project on the instrument of same treatment amblyopia, reach the purpose of rehabilitation as early as possible, belong to technical field of medical instruments.
(2) background technology
Amblyopia is the commonly encountered diseases in the childhood development process, it is generally acknowledged, amblyopia is grown unsound owing to macula retinae or the function inhibition causes.Amblyopia is a kind of growth irregularity ocular disease, and amblyopia is often by due to stravismus, anisometropia or the height ametropia.The hazardness of amblyopia and stravismus not only is visual disturbance, sees that object is smudgy, also be to lack perfect stereopsis, and stereoscopic vision is the social essential highest visual performance that adapts to scientific and technological high speed development.
Amblyopia can be regarded a kind of vision " atrophy " or visual cell " sleep " in essence as, and the effect of amblyopia instrument is to wake the visual cell of " sleep " up and increase indirectly and look or temper the vision of " atrophy " and directly increase and look with icon with colour code.This shows that the amblyopia instrument increases view principle can reduce two big classes: 1, icon function is tempered the vision of " atrophy "; 2, the coloured light function " is waken " visual cell up.
The amblyopia treatment method of widespread usage is a lot of at present, suppresses method and vision physiological stimulus therapy etc. as traditional covering method, non-traditional covering method, after image therapy, red flare, optics and medicine.Utilizing Hai Dingge light brush phenomenon and lenticular lenses to treat amblyopia also is the method that medically often adopts.
Hai Dingge light brush phenomenon has been utilized the principle of polaroid (being exactly polaroid).Polaroid is made by the dichroism material.When light wave when the polaroid, wherein one of orthogonal polarization components is polarized the sheet strong absorption, then absorb to another component a little less than, therefore can change natural light into line polarized light with polaroid.Ophthalmology medically calls Hai Dingge (Haidinger) brush to a kind of entopic phenomenon, and when the polarized light eyeglass by a rotation, when watching attentively facing to blue background, normal eye can be seen the pattern a branch of Caulis et Folium Oryzae that is being tied in the middle of resembling.The generation of Hai Dingge (Haidinger) brush phenomenon is owing to center on the result of henle's fibers (the fibers of Henle) effect of central fovea radial arrangement.
The scientific basis that Hai Dingge light brush phenomenon is used for carrying out amblyopia training is: the structure of human eye is quite complicated, and the formation mechanism of Haidinger brush is also very complicated.Except the participation of cornea, mainly ascribe the polarization effect that nerve fibre layer and cone cell acromere birefringence cause to, and in birefringence, combine chromatic dispersion and the outer field dichroism of cone cell.Mainly be to adopt incandescent light source to add blue optical filtering polaroid to realize that major defect is that electric filament lamp very easily damages, radiating effect is poor, influences the instrument life-span in the prior art, structure is complicated; The optical filtering polaroid can make the light intensity decreasing of light source be unfavorable for that the patient observes.
The scientific basis that lenticular lenses is used for carrying out amblyopia training is: the visual stimulus training can give retina cell most powerful stimulation by the stimulus modelity of bar grid.The bar grid uniform rotation of lenticular lenses, utilize the different bar grid of hard, spatial frequency to stimulate the amblyopia eye as stimulus, the bar grid that make the visual cell of amblyopia eye can both accept different directions on each orientation stimulate, improve the photoperceptivity of retina cell effectively, make the optic nerve aixs cylinder obtain activation, grow and the raising vision thereby visual center cell is strengthened.Because amblyopia resolving power in various degree is different, so vision should select the image of different space frequency from low to high to stimulate from low to high, could produce best amblyopia treatment effect.
Great majority have all comprised light brush training and grating is trained this two functions in the multi-functional amblyopia instrument of Xiao Shouing in the market, but extremely are being short of aspect the speed adjusting.Light brush polarizing filter has only a rotating speed, and only suitable part amblyopia patient that is to say, has only the part patient can see that tangible light brush trains, and causes using limited.The lenticular lenses function has two kinds, and a kind of is can not speed governing, and another kind is to adopt the speed governing of frame for movement externally-applied potential device, complex structure, and adjustment process is uncontrollable, influences the training for treatment effect.Original technology rotational speed regulation often is dumb.
Light brush revolving gear, i.e. Xuan Zhuan functional transparent film device is one of critical component of multi-functional amblyopia treatment system.Therefore, be badly in need of improving the performance of light brush revolving gear.
