Amblyopia therapeutic equipment

Abstract

The invention provides an amblyopia therapeutic instrument, comprising two parts: an optical mechanical structure system and a control circuit system; the two parts are organically combined with each other so as to form a therapeutic instrument with amblyopia disease treatment function; the control circuit system of the amblyopia therapeutic instrument comprises a keyboard, a keyboard detection circuit, a singlechip system, a speech prompting circuit, a grid, an optical brush, a coiling mechanism, a light source and a light source plate control circuit; the keyboard is used for inputting instructions which are detected by the keyboard detection circuit and transmitted to the singlechip system to be processed; subsequently, the singlechip system is taken as a micro-controller so as to emit control instructions to all control circuits and drive the execution mechanism to work; the optical mechanical structure system of the amblyopia therapeutic instrument of the invention consists of an upper machine cover, a lower case, a guideway component, a pupil adjusting mechanism, an optical brush rotation mechanism, a coiling mechanism and a light source rotation mechanism; the amblyopia therapeutic instrument has the advantages and effects that the treatment methods normally adopted by existing amblyopia therapeutic instruments in the market are integrated into a whole, the structure is optimized, the system performance is more excellent, the operation is more convenient and the man-machine interface is more friendly.

Description

(1) Technical field [0001] The invention relates to a medical device technical device for treating ophthalmic diseases such as amblyopia in children. (2) Background technology [0002] Amblyopia is a common disease in the development of children. It is generally believed that amblyopia is caused by underdevelopment or functional inhibition of the macula. Amblyopia is a developmental disorder of the eye. Amblyopia is often caused by strabismus, anisometropia, or a high degree of refractive error. The harmfulness of amblyopia lies not only in low vision and blurred objects, but also in the lack of perfect stereo vision, which is the most advanced visual function necessary for a society with rapid technological development. [0003] Amblyopia can be regarded as a kind of "shrinking" vision or "sleeping" visual cells in essence. The function of the amblyopia instrument is to use color codes to wake up the "sleeping" visual cells to increase vision indirectly or use icons to exe...

Problems solved by technology

The main advantage of the icon-type amblyopia device is that it can be directly exercised to improve vision. Its main disadvantage is that it is necessary to use a chromatic amblyopia device for correction of eccentric fixation amblyopia

Among them, the red flash therapy is realized by using red filter, which reduces the intensity of the irradiated light, making it more difficult for patients with amblyopia to see things, and reduces the curative effect; in the afterimage therapy, incandescent lamps are used to achieve strong light, which generates a lot of heat. The lifespan is low, which reduces the overall performance of the instrument and reduces the curative effect; dark blue filters and polarizers are used in light brush therapy, which reduces the intensity of the irradiated light, making it more difficult for patients with amblyopia to see things, and reduces the curative effect
