Portable light brush guided and positioned after-image amblyopia therapy instrument

Abstract

The invention relates to a household light brush guided and positioned portable amblyopia therapy instrument, which comprises a shell, a strong flash source, a covering sheet, an observation lens, a semi-reflective and semi-transparent mirror, a light brush and a light brush plate which is provided with sighting marks. Because the observation lens is a lens with high refractive index, the distance between the observation lens and the sighting marks of the light brush plate is shortened; the covering sheet is designed in a disc rotating adjustment mode, so that adjustment of the size of a covered point is facilitated, and the size is effectively reduced; and the portable light brush guided and positioned after-image amblyopia therapy instrument is also provided with a built-in flashlight which is supplied with power through a battery, so that an independent flashlight with big size and a charging circuit are eliminated, the whole size of the therapy instrument can be further reduced, and the therapy instrument is suitable for families.

Description

technical field [0001] The invention relates to a portable amblyopia treatment instrument which is suitable for home use and is guided and positioned by a light brush, which is mainly used for treating various children's amblyopia in families and communities, especially amblyopia caused by large-angle eccentric fixation. Background technique [0002] At present, the treatment for eccentric fixation mainly includes amblyopia training and drug therapy. The drug therapy commonly used in my country, such as Si Liba, belongs to dopamine drugs. It has been reported in the literature that it helps to improve eccentric fixation. But the training method is more important, there are mainly Haidinger brushes and various rear mirrors. From the 1950s to the 1970s, back-image mirrors similar to ophthalmoscopes were commonly used clinically. It is an objective treatment method, with a strong light source and a circular covering sheet in the center. During treatment, the patient needs to d...

Problems solved by technology

However, because the existing therapeutic apparatus uses a large light brush and an independent flashlight, the volume is relatively large, and the shading sheet is designed as a free module, which needs to be taken out during use, which is troublesome. , and the production cost is relatively high; on the other hand, due to its large size, it is inconvenient to carry and is not suitable for home use, so that patients must go to the hospital for treatment every time, and the treatment of amblyopia requires a considerable time process and needs to go through many times. If the treatment is not carried out for a sufficient number of times according to the course of treatment, the curative effect will not be achieved, which will cause great inconvenience to the treatment of patients, especially for those patients who are not local, and even need accommodation, which increases medical costs and burdens
