A new type of head fixation device for ophthalmic examination

Abstract

The invention discloses a novel ophthalmologic examination head fixing device which structurally comprises a head fixing frame, a base and an examination apparatus. The examination apparatus is mounted on the base, the head fixing frame is arranged at the front of the examination apparatus, the bottom of the head fixing frame is connected to a side surface of the base, the head fixing frame comprises a support column, a fixing frame, a nut, a lifting rod, a chin fixing seat, left and right fixing frames, perforated holes, a forehead cushion and fixture blocks, a transverse rod of the L-shapedsupport column is arranged at the bottom of the support column, the support column is connected with a side surface of the base, an end of the vertical rod of the support column is connected with themiddle of the bottom of the fixing frame, and the end of the vertical rod and the middle of the bottom of the fixing frame are of integral structures. The novel ophthalmologic examination head fixingdevice has the advantages that each of the left and right fixing frames comprises a fixing sheet, a guy rope and an arc-shaped block, accordingly, the novel ophthalmologic examination head fixing device is simple in structure, convenient to manufacture and low in cost, can be replaced at any time and is easy to operate, and users can easily master the novel ophthalmologic examination head fixing device; the arc-shaped blocks in arc-shaped designs can cling to ear structures of human bodies, accordingly, good fixing effects can be realized, and patients can be prevented from swaying in the left-right directions.

Description

technical field [0001] The invention is a novel head fixation device for ophthalmic examination, which belongs to the field of ophthalmic examination. Background technique [0002] General examination of the eye, including examination of the ocular adnexa and anterior segment. Ocular adnexa inspection includes inspection of eyelids, conjunctiva, lacrimal apparatus, eyeball position, and orbit. In long-term clinical practice, in order to prevent patients from disturbing treatment or detection during ophthalmic examinations and to fix the head, tightening fixation on both sides is usually adopted. , the fixed effect is not obvious, which leads to the failure of treatment or detection to achieve good results. Therefore, adopting effective fixation methods has become the development direction of modern medicine. [0003] It is often encountered that some patients such as the elderly and children shake their heads from side to side and do not cooperate with the treatment, which...
