Abstract
The utility model relates to an eyeball model, which is a teaching aid for briefing the structures and the functions of eyes. The utility model is characterized in that a phantom eye is scientifically divided into inserting blocks and additional eyeball peripheral tissue inserting blocks, a convex lens is used as a crystal body, etc. are improved. The utility model can display the structure of eyes and can also demonstrate the refraction functions of eyes so that the problems of the visual aid for explaining the formation of inverted image in the eyeballs and common eye diseases including myopic eye, telescopic eye, etc. are solved.
Description
Eyeball model is the teaching aid that the dioptric function of the structure of explanation eyes and explanation eyeball is united.The teaching aid of existing explanation eyeball structure is the eyeball phantom that is made of plastics.Eyeball phantom is divided into two hemispheres up and down, opens tangent plane and internal structures of eyeball that episphere promptly demonstrates wall of eyeball, and crystalline lens wherein and vitreum all are the pictograph bodies that constitutes with plastic opaque.The shortcoming of eyeball phantom is can only represent the structure of eyeball and the dioptric function that can not demonstrate eyeball.
The purpose of design Eyeball model is can demonstrate the principle that eyeball becomes inverted image and ametropia again for the structure that can represent eyeball on a teaching aid, to strengthen the knowledge of protection of youth eyes.
According to the principle of convex lens imaging, except that replacing the crystalline lens with suitable convex lens, vitreum should be transparent and dioptric not.In order to demonstrate ametropia, also need the eyeball of an adjustable axial length and be not subjected to the camera bellows that axial length of the eye changes to be influenced again, designed the Eyeball model of following structure for this reason.
The overall appearance of Fig. 1, Eyeball model
1. piece 6. chassis on the preceding hemisphere
2. piece 7. sliding trays under the preceding hemisphere
3. piece 8. pull bars on the eyeball surrounding tissue
4. piece 9. lens hangers under the eyeball surrounding tissue
5. column 10. legs
Eyeball model comprises the eyeball that simulates and its surrounding tissue.Two hemispheres before and after eyeball divides.Preceding hemisphere divides two (1,2) up and down again.Two joints before and after the eyeball surrounding tissue is also divided, prosthomere also divide two (3,4) up and down.Piece (1) connects together and links to each other with following piece (2,4) with the inserted block form on last piece (3) and the preceding hemisphere.Piece (2) connects together under piece under the eyeball surrounding tissue (4) and the preceding hemisphere, and is fixed on the chassis (6) by three columns (5).There are a sliding tray (7) and pull bar (8) to see Fig. 1 on the chassis (6).The internal structure of preceding hemisphere, identical with eyeball phantom except that crystalline lens is convex lens.
Placing eyeglass when 1 centimeters is adorned a lens hanger (9) as a means of the demonstration ametropia from the chassis before eyeball uses.
Fig. 2 .3. Eyeball model inner structure
Piece 11 rear quarters on the hemisphere before 1
The utmost point behind piece 12 rear quarters under the 2 preceding hemisphere
Piece 13 slits on the 3 eyeball surrounding tissues
Piece 14 crystalline lenses (convex lens sheet) under the 4 eyeball surrounding tissues
15 vitreums
The rear quarter of Eyeball model eyeball (11) piece of making no distinction of rank, its back utmost point is an inserted block (12), it can not contain retina.
The piece central longitudinal is to opening a slit (13) under the eyeball surrounding tissue, and rear quarter leg (10) is fixed in the sliding tray on chassis by slit (13).
Can explain internal structures of eyeball when opening piece (1.3), said that the back has just formed a cover altogether to them outside the two hemispheres of front and back, therefore after preceding hemisphere a tube, rear quarter (11) is in tube, can execute (particularly pull bar is executed) by machinery and change the axial length of eyeball, and not be broken to the camera bellows of picture with the position of regulating rear quarter.Changing axial length of the eye cooperates replacing crystalline lens (convex lens sheet) (14) can demonstrate the various dioptric situations and the cataract of eyeball again.
The vitreum of Eyeball model (15) has two kinds of method for expressing: the baton round of 1) inlaying flat glass with the two sides, front and back.2) inflate with the rubber pocket of carrying pipe and represent.
Fig. 4.Organize deutomerite near the eyes: eyeball surrounding tissue deutomerite (16) links to each other with prosthomere with the inserted block form.Can unload after having said the structure of organizing near the eyes.Unloading after the deutomerite could be piece (3.4) up and down separately.
Eyeball model and existing eyeball phantom compare, and its function has enlarged.The structure that not only can represent extraocular muscle and eyeball intuitively, can also the ocular demonstration eyeball in the formation of inverted image, myopia, farsightedness etc.
Claims (6)
1, a kind of teaching aid that simulates eyeball comprises the spheroid of a piecemeal and attached column and chassis.It is characterized in that: the device of a two hemispheres and an adjustable axial length of the eye before and after eyeball is divided into, and eyeball surrounding tissue inserted block add the combination that special crystalline lens, vitreum and posterior pole of eyeball inserted block are formed.
2, be the rear quarter that the preceding hemisphere of eyeball is divided into up and down two and adjustable positions according to the feature of the described Eyeball model of claim 1.
3, be two joints before and after its eyeball surrounding tissue is divided into according to the feature of the described Eyeball model of claim 1.Prosthomere is divided into two up and down again.
4, the feature according to the described Eyeball model of claim 1 is that crystalline lens is a convex lens sheet.
5, the feature according to the described Eyeball model of claim 1 is to represent vitreum with the glazing baton round of front-back, also can represent vitreum with the rubber pocket inflation of carrying pipe.
6, be that its posterior pole of eyeball can be made the inserted block that can dismantle according to the feature of the described Eyeball model of claim 1.
