Novel head fixing device for ophthalmologic examination

Abstract

The invention belongs to the technical field of ophthalmic instruments, in particular a new type of head fixation device for ophthalmic examination. Aiming at the problem that the head fixation equipment is not comfortable for patients to use during ophthalmology examination, the following scheme is proposed, including a base, the bottom of the base The four corners of the outer wall are all fixed with brake universal wheels by screws, and the top outer wall of the base is fixed with electric control slide rails by screws, and the top inner wall of the electric control slide rail is slidably connected with a slider, and the top outer wall of the slider passes A hydraulic cylinder is fixed with a screw, and one end of the piston rod of the hydraulic cylinder is fixed with a supporting plate by a bolt, and the outer walls of both sides of the supporting plate are fixed with a fixing plate by screws, and the fixing plate is an L-shaped structure. The outer wall on one side is fixed with a servo motor by screws. The invention can move freely, and can adjust the height of the equipment freely, so that the patient can relax the nervousness during the eye examination, and avoid the occurrence of the phenomenon that the buckle of the strap is too hard and crushes the scalp.

Description

technical field [0001] The invention relates to the technical field of ophthalmic instruments, in particular to a novel head fixation device for ophthalmic examination. Background technique [0002] General examination of the eye, including the examination of the ocular adnexa and anterior segment, the examination of the ocular adnexa includes the examination of the eyelid, conjunctiva, lacrimal apparatus, eyeball position and orbit. Treatment or detection to fix the head, usually by tightening the fixation on both sides, the fixation effect is not obvious and the treatment or detection can not achieve good results. Therefore, adopting effective fixation methods has become the development direction of modern medicine, and often encounters the elderly Some patients, such as children and children, shake their heads from side to side and do not cooperate with the treatment, which affects the normal inspection.

[0002] General examination of the eye, including the examination of the ocular adnexa and anterior segment, the examination of the ocular adnexa includes the examination of the eyelid, conjunctiva, lacrimal apparatus, eyeball position and orbit. Treatment or detection to fix the head, usually by tightening the fixation on both sides, the fixation effect is not obvious and the treatment or detection can not achieve good results. Therefore, adopting effective fixation methods has become the development direction of modern medicine, and often encounters the elderly Some patients, such as children, shake their heads from side to side and do not cooperate with the treatment, which affects the normal inspection

[0003] The existing head immobilization device for ophthalmic examination often has extremely low comfort due to the coldness of the equipment, and it will aggravate the patient's sense of fear. At the same time, the equipment is often used by multiple people. If it is not cleaned in time, bacteria will accumulate and the patient will suffer secondary infection. phenomenon occurs
