Novel ophthalmologic examination tool combined device

Abstract

The invention discloses a novel ophthalmologic examination tool combined device, which comprises a shell, wherein a fixed tray is welded on the inner side face of the middle of a shell by virtue of fixed pillars; at the upper side of the fixed tray, a retaining ring is fixed to the inner side face of the middle of the shell; fixing sleeves are uniformly distributed on the retaining ring, and the fixing sleeves are rotatably connected to the retaining ring; fixing rods are fixedly arranged on the lower side faces of the fixing sleeves; and color filters are arranged at the lower ends of the fixing rods. According to the novel ophthalmologic examination tool combined device, the various red and green color filters are simultaneously combined for selection, and the color filters, when used, can pop up and can be folded when not used, so that abrasion of the red and green color filters due to messy placement is prevented, and the color filters can be prevented from getting lost easily; meanwhile, a space is saved; the color filters can sequentially pop up from a strip-shaped through hole one by one when the fixing rods swing upwards as a rotating ring is pressed downwards; therefore, the color filters are simple to control; the color filters, which can be contracted in a rotating mode, are convenient to use; therefore, expanding and folding of each color filter are implemented; and subsequently, examination efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ophthalmic examination tools, in particular to a novel ophthalmic examination tool combination device. Background technique [0002] Maldives rods, red and green color filters, cover plates, cross mirrors, etc. are important and indispensable tools in the examination of binocular vision. Among them, the Maldives rods can be used for horizontal and vertical hidden strabismus; Strabismus; anisotropic examination; it has important reference value when evaluating binocular vision function and dealing with abnormal binocular vision function; red and green color filters are usually made of colored glass, and multiple red and green filters are often required in actual operation The selection of color chips is usually messy, easy to wear, and easy to lose when placed; on the other hand, each tool takes up a lot of space when placed scattered, which is inconvenient to use.
