Description

The extraocular muscles sight training instrument

Technical field

This utility model relates to a kind of medically rehabilitation sight training instrument, particularly a kind of extraocular muscles sight training instrument.

Background technology

Ciliary muscle (extraocular muscles) in the eyes depends on the crystalline lens, can allow crystalline lens need thickening or attenuation according to us at any time; Twenty-twenty people opens one's eyes and hopes that ciliary muscle can draw ligament and make the crystalline lens attenuation when a distant place, and then focus is extended naturally, and the article in a distant place will clearly image on the retina at rear.On the contrary, if will carefully look at nearby, the ciliary muscle that then will relax, ligament just can be along with it loosen, this moment the crystalline lens nature with regard to thickening, focus also will be near a lot, thus, no matter how far or how near article, that article can be seen is very clear.

Very busy of modern's life, use the time of computer also more and more longer, because long-time attention all concentrates on the focal length nearer or far away, or because long-time attention all concentrates in the focal length, cause the crystalline lens in the eyes thereby lose the ability of adjusting of thickening, attenuation, promptly adjust ability variation gradually.Prior art must be worn glasses and be corrected the zone of retina image-forming, but glasses worn for a long time, the myopia originally or the number of degrees of hypermetropia instead can be more and more darker, are not the ways of a solution really.Hence one can see that, and our suggestion sees through the vision rehabilitation teaching material plate of billboard body, with the quick far and near muscle of training extraocular muscles that changes, reaches the target of recovering vision, is only the method that a kind of vision rehabilitation improves.

Summary of the invention

The purpose of this utility model is for the ability of adjusting that solves crystalline lens thickening in the eyes, the attenuation problem of variation gradually, and a kind of extraocular muscles sight training instrument with rehabilitation function is provided.

For achieving the above object, this utility model includes at least:

One Billboard for the Activity body is provided with a framework on this Billboard for the Activity body top, and is provided with a plurality of pulleys in Billboard for the Activity body both sides;

One dragging track is provided with the anti-fall track of a convex at this dragging track inner bottom part, and is being provided with one group of J type signal line groove with respect to the anti-fall track of this convex top, the Billboard for the Activity body can be fixed in the dragging track slide;

One main control system, this main control system are arranged at dragging track one end, see through a shell main control system is coated, and are provided with a driving mechanism and in this main control system and drive memory control wafer, can remember the active stroke of Billboard for the Activity body;

One lower jaw adjustment is just by frame, and this lower jaw adjustment is connected with a lower jaw back cushion just by setting up the other end that places dragging track, is used for adjusting regular user's lower jaw, allows the extraocular muscles sight training instrument that user can easy manipulation this utility model.

This utility model designs and produces according to " the interior outward turning Rotation of vision physiology rehabilitation method improves standard ", main function is to assist to improve the myopia amblyopia, or interior outward turning function not good (on it inferior retcus and last inferior obliquus gradually be stranded attitudeization) and designing, utilize the synergism of extraocular muscles, move fast and turn far and near point, and movable extraocular muscles, and then reach the rehabilitation purpose of the physiological activity function of improving extraocular muscles.

The specific embodiment

See also Fig. 1, Fig. 2, shown in Figure 3, the embodiment of this utility model includes:

One Billboard for the Activity body 10, be provided with a framework 101 on these Billboard for the Activity body 10 tops, can be used for placing the pattern of eye focal length in the various training sets, and be respectively arranged with a plurality of pulleys 102, Billboard for the Activity body 10 can be slided front and back in Billboard for the Activity body 10 both sides;

One dragging track 20, please consult shown in Figure 4 simultaneously, be provided with the anti-fall track 201 of a convex at these dragging track 20 inner bottom parts, and be provided with one group of J type signal line groove 202 with respect to the anti-fall track of this convex 201 tops, can place the electric signal line, run through whole rail, Billboard for the Activity body 10 can be fixed in the dragging track 20 slide, and be unlikely to come off dragging track 20;

One main control system 30, this main control system 30 is arranged at dragging track 20 1 ends, see through a shell 301 this main control system 30 is coated protection, this main control system 30 includes a driving mechanism 302 and and drives memory control wafer 303, see through the program management that drives memory control wafer 303 memory internals, make these driving mechanism 302 control Billboard for the Activity bodies 10 in dragging track 20, do the slip of systematicness, or set the travel frequency of suitable user, effectively train the extraocular muscles of user, reach the purpose of rehabilitation extraocular muscles, and be provided with a fixed support instrument 204 in dragging track 20 stage casings, make dragging track 20 held stationary in the plane, see also shown in Figure 5 again, be provided with stepper drive motor 3021 in driving mechanism 302 inside, the belt 3023 that sees through on the driving wheel 3022 connects drive Billboard for the Activity body 10, dragging track 20 1 ends and other end driving mechanism 302 are provided with one group of location inductive switch 203 again, connect in driving memory control wafer 303 again, this group location inductive switch 203 can be responded to localized action to Billboard for the Activity body 10, and outcome record driven memory control wafer 303 inside, at any time do the action of renewal, utilize one group of fixing hole 3024 that driving mechanism 302 is fixed on the dragging track 20, make stepper motor 3021 can see through driving wheel 3022 and drive belt 3023, control Billboard for the Activity body 10 advances or falls back, the extraocular muscles of training user;
