Description

A kind of Sight corrector

This utility model relates to Sight corrector.

The Sight corrector of prior art is made up of eyeshield 1, trachea 2 and actuator 3 at present, shown in accompanying drawing 5 and 6.Wherein, this actuator 3 is made of the spherical air bag of colloid, actuator 3 make malleation that the gas in the eyeshield produces or negative pressure be exactly air bag originally experience palm exert pressure or put press and malleation or negative pressure, wherein, gas is malleation when the air bag pressurized, and is negative pressure when gas is bullied the suction of capsule when gasbag pressure disappears.Because myopia is longer because of eyeball back/forth diameter, secondly be because of the crystal flexibility is bigger, make due to the increase of crystal refractive power.According to these characteristics, operate Sight corrector with " fast pressure is put method slowly ", making wherein, air pressure increases fast, eyeball, can make eyeball back/forth diameter shorten curvature and diminish through treatment after a while because of being subjected to gas pressure to the eye socket sunken inside, improve the dioptric system of eye, vision is improved to normally.And hypermetropia mostly is eyeball back/forth diameter and grows too short or due to the crystal flexibility reduces, adopt during the treatment hypermetropia " pressing quick release technique slowly ", the eyeshield internal gas pressure is reduced rapidly, produce negative pressure, slight convex forwards attracts eyeball, thereby elongate gradually in the footpath after making eyeball, and it is big that the crystal flexibility becomes, and just can form clear reflection on retina.But the Sight corrector of prior art is to exert pressure the back when eyeball is produced pressure with hands to actuator 3, because it is limited in its eyeshield 1 volume inside, make gas when arriving eyeball, promptly disengage in a twinkle by the silhouette edge of eyeshield 1, make the malleation poor effect that should produce in eyeshield 1, therefore the effect of Sight corrector commonly used is remarkable like that not as expection.

Therefore, in view of this design people is according to operation practical experience for many years, and after long-term trial-production, research, improvement, obtains effect certainly finally, and successfully finish this utility model.

The purpose of this utility model be to provide a kind of structure tight, eyeball is produced effective positive and negative pressure, thereby the Sight corrector of correct vision effectively.

The purpose of this utility model is achieved in that the Sight corrector that is provided comprises two eyeshields, trachea and actuator, is characterized in that: described eyeshield is made up of cover, stressed and spacing frame; Described cover is hat, and its front end is provided with the projection of band through hole, is provided with straight edge at its edge; Described stressed is and the isomorphous thin slice of cover edge profile, is provided with therebetween than thin slow tabletting around stressed; Spacing frame is a ring body, is bent to form groove in its front side, and its rear side is the overlaying frame that a spacing is arranged with groove, and its cross section forms

Shape; The edge plug of described cover is located between cover and the spacing frame and is positioned in the groove for described stressed in this groove, perhaps directly is shaped in the spacing place of eyeshield spacing frame, and cover and spacing frame directly are incorporated into the groove place.

The new shape of this practicality has good effect, and when the manipulation actuator made gas send into two eyeshields by trachea, the space in the eyeshield was abundant, and the compact conformation of eyeshield, the gas that is pressed into does not leak, because stressed slow tabletting is thinner, directly is pressed on eyelid during pressurized simultaneously, and be the extrusion of ogee with eyeball, stressed thicker part then is pressed on the socket of the eye limit of eyeball, thereby forms effective malleation, otherwise, therefore form effective negative pressure, correct vision effectively.

Below in conjunction with embodiment and conjunction with figs. this utility model is elaborated.

Accompanying drawing 1 is a perspective view of the present utility model;

Accompanying drawing 2 is STRUCTURE DECOMPOSITION sketch maps of the present utility model;

Accompanying drawing 3 is structure cross-sectional schematic of the present utility model;

Accompanying drawing 4 is another embodiment cross-sectional schematic of structure of the present utility model;

Accompanying drawing 5 is user mode figure of Sight corrector commonly used;

Accompanying drawing 6 is structure cutaway views of Sight corrector commonly used;

Accompanying drawing 5 and 6 was narrated at leading portion, and the corresponding relation of the used label of accompanying drawing 1-4 and each parts is as follows:

Eyeshield 10, cover 111, projection 112, through hole 113, edge 114, stressed 115, slow tabletting 116, spacing frame 117, groove 118, overlaying frame 119, spacing 120, trachea 20, actuator 30;

From accompanying drawing 1-3 as seen, Sight corrector provided by the utility model comprises two eyeshields 10, trachea 20 and actuator 30.This utility model has mainly been done improvement to eyeshield.Described eyeshield 10 is made up of cover 111, stressed 115 and spacing frame 117.Be provided with the projection 112 of being with through hole 113 at cover 111 front ends that are hat, be provided with straight edge 114 at its edge; Described stressed 115 is and the isomorphous thin slice of cover 111 edges, 114 profiles, is provided with therebetween than thin slow tabletting 116 around stressed 115; Described spacing frame 117 is ring bodies, bends to groove 118 in its front, is the overlaying frame 119 that a spacing 120 is arranged with groove 118 surveying thereafter, its cross section shape face

Shape, the edge 114 of described cover 111 is filled in this groove 114, and described stressed 115 is located between cover 111 and the spacing frame 117 and is positioned in the groove 114.

When gas is sent into eyeshield 10 by trachea 20, gas is expanded into arc with stressed 115, and because the slow tabletting 116 on stressed 115 is thinner, so should directly be pressed on the eyelid by slow tabletting, and do the extruding of ogee with eyeball, stressed thicker part then extrude the socket of the eye limit of eyeball and shape face malleation.When negative pressure, because stressed #115 retreats earlier, 119 of the spacing 120 of this spacing frame 117 and overlaying frames are pressed on face, make eyeball be subjected to suction and projection, produce negative pressure.Therefore, can correctly carry out malleation, negative-pressure operation.

Another embodiment of this utility model is stressed 115 spacing 120 places that directly are shaped in eyeshield spacing frame 117, makes cover 111 and spacing frame 117 directly be incorporated into groove 118 places.Its effect is same as described above.
