Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Such as figure 2 As shown, the light source rotating mechanism of a low vision treatment instrument of the present invention is composed of a light source lens assembly 1, a light source cone 2, a travel switch assembly 3, a translation stage assembly 4, a motor assembly 5 and a light emitting diode assembly 6. The light source conical surface 2 is fixed on the light source lens assembly 1 with a slotted taper end tightening screw. The limit switch assembly 3 is fixed on the motor assembly by screws.

[0037] Such as image 3 As shown, the light source lens assembly 1 is composed of a slider 1, an adjusting support 12, a support rod 13, a lens frame 14, a light source lens 15 and a lens pad 16. The light source lens 15 is fixed on the lens frame 14 after the lens pad 16 is added. The lens frame 14 and the adjustment support 12 are connected by a support r...

Abstract

The invention provides a light source rotation mechanism of an amblyopia therapeutic instrument, which is characterized in that the light source rotation mechanism consists of a light source lens component, a light source conical surface, a stroke switch component, a translation platform component, a motor component and an LED; the light source conical surface is fixed on the light source lens component by a channel cone end locking screw; the stroke switch component is fixed on the motor component by a screw. According to the requirement of the children amblyopia function train items, the light source can rotate by a certain angle so as to use the light source illumination system passage of required colours, thus achieving the training object. The light source rotation mechanism adopts asinglechip to control the stepping motor so as to drive the light source circuit board to rotate by a precise angle, thus having extremely high reliability.

Description

(1) Technical field [0001] The present invention relates to a medical device technical device for treating ophthalmic diseases such as amblyopia and strabismus in children. Specifically, it relates to a medical device technical device related to light-emitting elements. It provides a brand-new and optional five-color LED light source for patients A variety of training programs are carried out on the same instrument for treating amblyopia to achieve the goal of rehabilitation as soon as possible. (2) Technical background [0002] Amblyopia is a common disease in the development of children. It is generally believed that amblyopia is caused by imperfect or functional inhibition of the retinal macula. Amblyopia is a developmental disorder of the eye. Amblyopia is often caused by strabismus, anisometropia, or high refractive error. The hazards of amblyopia and strabismus are not only low vision and blurred objects, but also lack of perfect stereo vision. Stereo vision is the most ad...
