Abstract
The utility model relates to a vision disturbance tubular visual field experiences ware. Its characterized in that a left side lens and right lens all divide into two regions, and the middle part of left lens and right lens is irregular regionally be light transmission region, represent the impaired remaining field of vision still afterwards in the field of vision, periphery beyond the irregular region of a left side lens and right lens is light transmission region not, the field of vision that can't see after impaired as the field of vision. The utility model discloses a tubular visual field experiences the ware, can let the student obtain tubular visual field's true experience to tubular visual field patient's misery can be known, the feelings of student to patient's love are improved. This experience ware can be extensive be applied to teaching of medical colleges and schools ophthalmology and nursing for aged teaching, but also wide application in the healthy propaganda and education of the old person of community lets the old person experience the symptom of tubular visual field, help discernment glaucoma.
Description
Technical field
A kind of teaching aid of this utility model design, is specially a kind of visual disorder tubular visual field device for experiencing.
Background technology
The visual field is exactly when eyes watch a fixing object attentively to dead ahead, can be additionally seen other object in certain space around this object simultaneously, and this spatial dimension that can see is called the visual field. Glaucoma patients is discharged to be obstructed due to aqueous humor and is caused intraocular pressure rising, and destroying retinal and optic nerve gradually, patient constantly shrinks in the visual field. When shrinking to a certain extent when visual field damage, can only see very narrow scope, just as seeing thing by a pipe, i.e. tubular visual field. The student of medical colleges and schools can acquire this knowledge in teaching, but owing to comparing abstract indigestion, have impact on teaching efficiency. Glaucoma is apt to occur in middle-aged and elderly people, within more than 40 years old, accounts for 90%. Along with China steps into aging society, old people suffering from glaucoma person increases therewith, and glaucoma is the main cause causing old people blind. But glaucoma morbidity has certain invisible, most patients can not find that oneself suffers from glaucoma in time, if strengthening propaganda and education, allows numerous patient will appreciate that tubular visual field, then must help early diagnosis and treatment, keeps the vision of patient. Therefore, if can there be a kind of visual disorder tubular visual field device for experiencing that medico and the common people can be allowed to be understood that the pipe visual field, allow them obtain an actual experience, will be highly profitable.
Utility model content
For problems of the prior art, the purpose of this utility model is in that to provide the technical scheme of a kind of visual disorder tubular visual field device for experiencing.
Described visual disorder tubular visual field device for experiencing, including left frame, correct frame, left eyeglass, right eyeglass, left eye cover, right eye cover, nose frame, framework connects band and headband, left frame and correct frame are provided with nose frame, left eyeglass and right eyeglass are arranged on left frame and correct frame with left eye cover and right eye cover, being connected band proximally by framework and be connected of left frame and correct frame, left frame is connected by headband with the far-end of correct frame, it is characterized in that described left eyeglass and right eyeglass are all divided into two regions, the central region of left eyeglass and right eyeglass is transmission region, represent the visual field of the impaired rear also remaining in the visual field, periphery beyond the central region of left eyeglass and right eyeglass is light tight region, as the visual field that the visual field be can't see after impaired, described left eye cover and right eye cover be provided with a circle groove, left frame and be provided with the convex tendon of interlocking groove on correct frame, left eye cover and right eye cover are arranged on left frame and correct frame by groove with coordinating of convex tendon, described left frame is provided with framework with the proximal lateral of correct frame and is connected band mounting groove, and framework connects band two ends and is provided with spacing cingulum, and the spacing cingulum clamping that framework connects band is spacing in framework connection band mounting groove.
Described visual disorder tubular visual field device for experiencing, it is characterised in that described left eye cover and right eye cover are all light tight.
Described visual disorder tubular visual field device for experiencing, it is characterised in that described left eye cover and right eye cover are respectively provided with elastic buffer circle near user face side, and elastic buffer circle is demountable structure.
Described visual disorder tubular visual field device for experiencing, it is characterised in that be provided with the day word being easy to headband length adjustment on described headband and buckle.
Described visual disorder tubular visual field device for experiencing, it is characterised in that be provided with the slot of grafting eyeglass, left eyeglass and the grafting respectively of right eyeglass in described left frame and correct frame and be arranged in the slot of left frame and correct frame.
