Light brush revolving gear of amblyopia therapeutic equipment

Abstract

The invention provides an optical brush rotation mechanism of an amblyopia therapeutic instrument, consisting of a grid optical brush rotation mechanism, a pattern frame, a tracing body bracket rear cover, a right baffle, a left baffle, an upper cover plate baffle, a tracing glass, a small pressing plate and a crossing channel barrel head screw; the grid optical brush rotation component consists of a rear cover, a motor, a lower cover, a coupler, a small pulley, a transmission belt, a large pulley, a large pulley transmission wheel, a bearing, a bearing seat, a grid optical brush assembly body, a bearing lower pressing plate, a bearing upper pressing plate and an upper cover; the grid optical brush assembly body consists of a grid assembly frame, a disassembly hole, a lower grid assembly pad, a polarizing filter and an upper optical grid assembly pad. The optical brush rotation mechanism adopts a DC motor to drive the transmission wheel so as to drive the grid optical brush assembly body to rotate at suitable speed by the rotation of the synchronous belt. The whole rotation device is arranged inside the shell which consists of the front cover and the rear cover and is safe and reliable. The grid optical brush assembly body is replaceable; the optical brush sheet can be added when the optical brush training is required and the optical brush sheet can be replaced by the grid sheet when the grid sheet is required.

Description

(1) Technical field [0001] The invention provides a light brush rotating mechanism of an amblyopia treatment instrument, which is a medical device for treating ophthalmic diseases such as children's amblyopia and strabismus, and specifically relates to a medical device technical device for replacing light-emitting elements of functional pictures, so that patients can be treated on the same machine. Amblyopia equipment is used for training various items to achieve the purpose of rehabilitation as soon as possible, which belongs to the technical field of medical equipment. (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 and strabismus lies not only i...

AI Technical Summary

Problems solved by technology

The light brush polarizing filter has only one rotation speed, which is only suitable for some amblyopia patients, that is to say, only some patients can see the obvious light brush for training, resulting in limited application

There are two functions of the grating sheet, one is non-adjustable speed, and the other is to use a mechanical structure plus a potentiometer to adjust the speed. The structure is complex and the adjustment process is uncontrollable, which affects the training and treatment effect.

The original technology is often inflexible in speed adjustment
