Abstract
The invention provides an orthoptic and binocular imaging capability training instrument and relates to a medical care apparatus, which is mainly used for strabismic and asthenopic binocular imaging capability training and non-operative orthopia. The instrument essentially consists of a shell, a left eye plate, a right eye plate, a drive part, etc. The left eye plate and the right eye plate can be opened and closed, at least one of which keeps open when in use. In such a way, a cross-eye and a recessive eye are kept gazing for a long time and the plate at the side of a dominant eye or an entopic eye keeps open or closed anytime according to the frequency set up as per the condition of each patient so as to form the discontinuous gaze of the dominant eye or the entopic eye. Therefore, the purpose of leading two eyes to carry out discontinuous and simultaneous gaze is fulfilled. As a result, a powerful binocular imaging impulse is formed and the gradual recovery and creation of binocular imaging function are achieved.
Description
Affiliated technical field
The present invention relates to a kind of medical health appliance, particularly relate to a kind of orthpia and eyes and close picture ability training device.
Background technology
At present, existing technology is by natural fusion to the training majority that the eyes in the amblyopia treatment close as ability, and some are arranged is with the computer software training, but effect is all undesirable, particularly simple eye amblyopia and strabismic amblyopia; The most of still dependence of the rectification of stravismus operation is finished, and can not be guaranteed after the operation that the fusion function (promptly closing as ability) of eyes recovers normally, and eyes do not close the picture ability, squinting eye cannot say for sure that also card reaches normal position state.In addition, do not close the eyes of picture ability, people's brain can preferentially use dominant eye all the time, and the inferior position eye can be suppressed usually, will cause the inferior position eye vision to descend to form the result of amblyopia or Secondary cases amblyopia, and existing technology is difficult to address this problem all the time.
Summary of the invention
In order in amblyopia and stravismus treatment closing as ability of eyes to be trained, orthpia of the present invention and eyes close as the ability training device and are graded and formed by shell and left eye catch, right eye washer, drive division.Left eye catch and right eye catch can be opened and can close, the state that has at least a place to be out in left eye catch during use and the right eye catch.Like this, squinting eye or inferior position eye are watched attentively for a long time, the washer of dominant eye or normotopia eye one side opens and closes according to the frequency that the situation of individual patients is provided with, thereby the interruption that forms dominant eye or normotopia eye is watched attentively, so just reached and allowed eyes be interrupted the purpose of watching attentively simultaneously regularly, form a kind of strong eyes and close the picture impulsion, progressively reach recovery and create the purpose that eyes close the picture function.

Among the figure: 1. shell; 2. emptying aperture; 3. left eye washer; 4. right eye washer; 5. electric lead; 6. fixing band; 7. controller; 8. spring or rubber band; 9. spring or rubber band; 10. electric magnet; 11. electric magnet; 12. the ironwork of images of left and right eyes washer; 13. the active locating shaft of right eye washer switch; 14. the active locating shaft of left eye washer switch; 15. the adjusting device of current switching frequency; 16. instrument starting switch; 17, the on off state setting device of left eye washer and right eye washer.
The specific embodiment
As shown in Figure 1: the present invention is mainly graded by shell (1), left eye catch (3), right eye washer (4) and drive division and forms; Shell adopts plastics, metal material or other plastic materials to make, and the right and left respectively is provided with an emptying aperture (2) that supplies sight to pass through; For easy to use, a fixing band (6) can be set.
As shown in Figure 2, left eye washer and right eye washer are divided into two parts, a part is the part (12) that is subjected to solenoid actuated made of iron, another part is to be used for the part of sight of the corresponding eye of in emptying aperture (2 among Fig. 1) shield, can be made into discoid (3,4) or rectangular-shaped or semicircle shape or other shapes, respectively be provided with a hole on the images of left and right eyes washer, the hole is through on the corresponding locating shaft (13,14); Drive part is made up of controller (7), electric lead (5) and electric magnet (10,11), and wherein electric magnet (about branch two groups) is contained in the shell, and is corresponding with the part of ferrum in left eye washer and the right eye washer, the Current Control of controlled device output.When electric magnet cut off the power supply, when being "open" state with rubber band or spring (8,9) traction washer, emptying aperture was not blocked, and the sight of the eye of its respective side is passed through emptying aperture; During the electric magnet energising, when attracting washer to be "off" state, the emptying aperture shield is lived, the sight of the eye of its respective side can not be passed through emptying aperture.Controller (7) is made up of control circuit and controller housing, control circuit can provide the alternative electric current of frequency break-make on demand, being interrupted provides electric current to electric magnet by electric lead (5), electric magnet also is the pattern of interruption to the captivation of washer, thereby driven the Kai Heguan of left eye washer and right eye washer respectively, its current switching frequency (being the switching frequency of washer) is within the scope of per minute kind 1 to 120 time.
Controller is provided with the on off state setting device (17) of instrument starting switch (16) and electromagnet current break-make frequency regulation arrangement (15) and left eye washer and right eye washer.
The above only is preferred embodiment of the present invention, is not the present invention is done any pro forma restriction, and any equivalent embodiment that does not break away from essence of the present invention all belongs within the technical scheme scope of the present invention.
Using method of the present invention and beneficial effect: picture ability training dress is closed in orthpia of the present invention and eyes Put as wearing common spectacles and with fixed band it is worn at the moment, the washer of slanting eye or inferior position eye one side is protected Be held in "open" state, close when opening when being arranged to the washer of emmetropia or Dominant eye one side by certain frequency State, make the long-term object of regard picture of slanting eye or inferior position eye, and normotopia eye or Dominant eye often have an opportunity to participate in Object of regard picture but can not constrain watching attentively of another eye, like this, the image that eyes are seen simultaneously is in brain Two images that reflect cause continuous repeated impacts, brain to the corresponding cell in the cerebral cortex and nerve Be fused into one with its acceptance and with two images gradually, recover and improved the picture ability of closing of eyes. Use The present invention can allow squinter's slanting eye be subjected to eyes to close the control of image force and transfers the normotopia eye to, thereby further Reach stereopsis; Can allow the amblyope progressively recover to close the picture ability, thereby reach the stereopsis of eyes, particularly The little effect of binocular vision gap is especially remarkable.
Claims (2)
1, a kind of orthpia and eyes close picture ability training device, it is characterized in that it is mainly graded and formed by shell and left eye catch, right eye washer, drive division, and left eye catch and right eye catch can be opened and can close.
2, orthpia according to claim 1 and eyes close picture ability training device, the state that has at least a place to be out in left eye catch when it is characterized in that using and the right eye catch.
