Bearing device for ophthalmic examination

Abstract

The invention belongs to the technical field, and particularly relates to a bearing device for ophthalmic examination. Through the arrangement of a head bearing mechanism and an instrument bearing mechanism, when a patient receives strabismus examination of the eyes, bearing of the patient and an examination instrument is facilitated, the fatigue feeling of the patient and inconvenience in instrument holding are reduced, and examination convenience is improved; through cooperation of a driving assembly, a rack and multiple detection prism groups, the orientation of the prisms can be changed only by pushing or withdrawing the rack according to detection requirements in a detection process, adjustment and disassembly of too many parts are not needed, more convenience and rapidness are achieved, the number of the detection parts of the whole device is reduced, operation convenience is improved, and an integration degree is high; and by arranging a transverse adjuster and a lifter, the driving assembly can be rapidly adjusted, the eye examination requirements of different patients are met, and adjustment is convenient and rapid.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a supporting device for ophthalmic examination. Background technique [0002] The eye is an important organ for human visual collection. It is used to distinguish different colors and the brightness of light, and convert this information into nerve signals and send it to the brain. The eye itself is also a very fragile organ, which is prone to congenital diseases or acquired external injuries. Causes eye lesions, among which strabismus is a common eye disease, mainly reflected in the inability of both eyes to fixate on the target at the same time, which will have a greater impact on the patient's appearance and visual senses. [0003] At present, the prism detection method is usually used for strabismus detection, that is, to cover one eye of the patient, and then use different gradient prisms to test the non-covered eye in turn, until the patient's eyes no longer move to get th...

Problems solved by technology

[0003] At present, the prism detection method is usually used for strabismus detection, that is, to cover one eye of the patient, and then use different gradient prisms to test the non-covered eye in turn, until the patient's eyes no longer move to get the degree of strabismus, and then exchange the test to get the patient's two eyes. The strabismus state of the eyes can be easily corrected by surgery, wearing special glasses or correction training in the later stage. At present, when performing strabismus inspection, the doctor usually holds a prism row for detection, that is, multiple prisms with different gradients are set on a strip. According to the prism The cross-section is triangular at the bottom, the vertical horizontal plane is for checking the degrees of strabismus up and down, and the parallel horizontal plane is for checking the degrees of left and right strabismus, and such a hand-held method is prone to shaking, fatigue in a static state for a long time, and the distance between the prism row and the patient is difficult to grasp problem, which in turn causes the inspection data to be inaccurate. At the same time, since the prism rows with different orientations are set on different slats during the inspection, it is necessary to repeatedly take multiple prism rows for testing during the inspection, and it is easy to have too many inspection tools. The problem of easy storage and cumbersome inspection process does not meet the needs of fast and convenient inspection
