Pupillary distance adjusting device of amblyopia therapeutic equipment

Abstract

The invention provides a pupil adjusting mechanism of an amblyopia therapeutic instrument, consisting of two parts: a lens component and a drawtube component. the drawtube component is arranged on the case of the amblyopia therapeutic instrument by screws; the lens component is arranged on the guideway of the amblyopia therapeutic instrument; the lens component consists of an ocular frame, an ocular lens, a supporting rod, an adjusting supporter, a pad and a sliding block; the ocular drawtube consists of a pressing plate, a transverse pulling plate, an ocular slideway, a right ocular and a left ocular; the structure of the left ocular is similar to that of the right ocular and the difference thereof is that the gap of the right shielding plate of the right ocular faces to the rear part and the gap of the left shielding plate of the left ocular faces to the front part; the ocular drawtube in the pupil adjusting mechanism is divided into a left drawtube and a right drawtube with the distance to be adjustable. The ocular of the invention has large calibre; the patterns of transparent films and rotation function sheet near the focus are imaged, thus facilitating the observation and training. The glass sheet in the dual-ocular drawtube is used for separating the ocular lens from the eye of human, thus ensuring the cleanness and imaging quality of the ocular lens.

Description

(1) Technical field [0001] The invention provides an interpupillary distance adjustment mechanism of an amblyopia treatment instrument, which relates to a medical device for treating ophthalmic diseases such as children's amblyopia and strabismus, and specifically relates to a medical device technical device for observing object imaging with human eyes, belonging to The field of medical device technology. (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 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 technologi...

AI Technical Summary

Problems solved by technology

The monocular amblyopia devices currently on the market have no interpupillary distance adjustment mechanism, and the binocular amblyopia devices do not consider the problem of interpupillary distance adjustment. Long-term training under the condition of inappropriate interpupillary distance will lead to new vision development damage.
