Novel head fixing device for ophthalmologic examination

Abstract

The invention belongs to the technical field of ophthalmologic instruments, in particular to a novel head fixing device for ophthalmologic examination, and aims at solving the problem of uncomfortableuse when the ophthalmologic examination is performed on a patient by means of the head fixing device. A scheme is proposed, and the head fixing device includes a base, universal wheels with brakes are fixed to the four corners of the bottom outer wall of the base through screws, and an electrically controlled slide rail is fixed to the top outer wall of the base through screws; the top inner wall of the electrically controlled slide rail is slidably connected with a sliding block, and a hydraulic cylinder is fixed to the top outer wall of the sliding block through screws; a support plate isfixed to one end of a piston rod of the hydraulic cylinder through bolts, fixing plates are fixed to the outer walls at both sides of the support plate through screws, the fixing plates are of L-shaped structures, and servo motors are fixed to the outer walls at one sides of the two fixing plates through screws. The head fixing device can move freely, and the height of the head fixing device can be freely adjusted, so that psychology stress of the patient can be reduced when eyes are inspected, thereby avoiding the phenomenon that the scalp is bruised by overhardening strap snaps.

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
