Description

An easily adjustable examination table for ophthalmology

technical field

The invention relates to an examination table for ophthalmology, in particular to a convenient adjustment type examination table for ophthalmology.

Background technique

The full name of ophthalmology is "Ophthalmology Specialist". Ophthalmology is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. In 1851, Helmholtz in Germany invented the ophthalmoscope, and ophthalmology truly became an independent discipline. Doctors who can engage in ophthalmology need graduates of this major, and they must be engaged in ophthalmology in tertiary hospitals and higher medical colleges before they can carry out clinical medical treatment and teaching work. Common ophthalmic diseases include: central serous retinopathy, dry eye disease , sympathetic ophthalmia, night blindness, blindness, amblyopia, astigmatism, trachoma, cataract, diabetic retinopathy, conjunctivitis, presbyopia, color blindness, heterochromia iris, retinitis pigmentosa, central retinal artery occlusion, retinal detachment, myopia, hyperopia, Needle eye, snow blindness, chalazion, glaucoma, floaters, etc., general inspection of the eye, including eye adnexa and anterior segment inspection, eye adnexa inspection including: eyelid, conjunctiva, lacrimal organ, eyeball position and orbital inspection; eyeball Anterior segment examination: including examination of cornea, anterior segment of sclera, anterior chamber, iris, pupil, and lens. Common ophthalmic equipment includes vision chart, tonometer, slit lamp, direct/strip light retinoscopy, color vision examination table, and perimeter , film reading light, A/B ultrasound examination machine, refractometer, keratometer, fluorescein fundus imaging machine, ophthalmic retrobulbar injection needle, lacrimal duct irrigation needle, eyelash extraction forceps, retinal photocoagulation laser equipment, retinal freezer, Operating bed, operating lamp, conventional external eye surgical instruments, surgical microscope, microsurgical instruments, intraocular electromagnets.

The existing ophthalmology examination table usually adopts a traditional fixed structure and cannot be adjusted, which not only cannot meet the needs of different personnel, but also cannot effectively support different personnel, which increases the burden on users and seriously affects the eyes of patients. Therefore, it is urgent to develop a convenient and adjustable examination table for ophthalmology, which is flexible in structure, can be adjusted, can meet the needs of different personnel, and can effectively support different personnel.
