LED strabismus inspection instrument

Abstract

The invention discloses an LED strabismus inspection instrument. The instrument comprises a base, an arc-shaped lamp frame and a lifting and lowering chin supporting frame, the front end of the base is provided with a controlling seat, a vertically upward lifting and lowering upright column is arranged above the controlling seat, the top of the lifting and lowering upright column is provided withthe horizontally arranged arc-shaped lamp frame, the arc-shaped lamp frame can be rotated around the lifting and lowering upright column, and therefore the switching inspection of inner, outer, upperand lower strabismus inspection can be achieved; a sliding seat is arranged above the base, the sliding seat is located on the side, away from the controlling seat, of the sliding seat, and the lifting and lowering type chin supporting frame is installed on the sliding seat. The instrument has the advantages that by the arrangement of the arc-shaped lamp frame, a to-be-inspected person observes the position of a light bead on the arc-shaped lamp frame, the strabismus degree of the deviating eyes of the to-be-inspected person is rapidly judged, the structure is simple, the operation is convenient, and the to-be-inspected person only needs to maintain the same posture and the inspection of all of the strabismus items can be completed.

Description

technical field [0001] The invention relates to the field of medical inspection equipment, in particular to an LED strabismus inspection instrument. Background technique [0002] Strabismus is a manifestation of amblyopia. Strabismus can be divided into esotropia, exotropia, upward and downward squint. Existing strabismus inspection methods include corneal light reflection method, prism method, synoptic machine inspection, etc. [0003] The applicant found that there are at least the following technical problems in the prior art: 1. The corneal light reflection method is only suitable for patients with monocular fixation dysfunction who cannot fix colloids or have limited eye movement. This method can only roughly estimate the oblique angle. The results of the prism test should also be referred to when calculating the surgical volume; 2. The prism test for strabismus includes the prism alternate covering method, the prism covering and uncovering method, and the prism cornea...

Problems solved by technology

[0004] The object of the present invention is to provide an LED strabismus inspection instrument in order to solve the above problems, so as to solve the technical problems of using a prism to perform strabismus inspection in the prior art, which takes a long time and has low accuracy of detection data.
