Abstract
The utility model relates to a myopia prevention and treatment instrument with optical induction, which is used for preventing and curing accommodative myopia. The utility model comprises an eyepiece and a visual target, and two viewing tubes are connected to one rotating shaft through a support bracket. One end of the viewing tube is provided with a convex eyepiece, and the other end is provided with a visual target lens. The inner sides of the two visual target lenses are accompanied with identical picture visual targets, the visual target lenses are arranged on an inner sleeve barrel, and an operating device which causes the inner sleeve barrel to move longitudinally is arranged on the inner sleeve barrel. The utility model has the advantages of simple structure and convenient use and operation. Patients can optionally adjust according to different characteristics and requirements, such as adjusting the range, the speed, etc. of the visual target movement. The induction control efficiency is good, and the carryover is convenient.
Description
Technical field
This utility model relates to a kind of improved instrument for prevention and cure of myopia, is used for prevention, treatment accommodative myopia.
Background technology
Medical research shows, myopia, especially to be divided into accommodative myopia be that pseudomyopia and axial myopia are the too high property of true myopia and refractive index myopia three classes to myopia of student, and accommodative myopia is basis and the prerequisite that causes axial myopia, therefore, the treatment accommodative myopia is the important means of prevention axial myopia.The method that present medical circle is used for the treatment of accommodative myopia is more, concludes and gets up can be divided into optical induction method, massotherapy, electric acupoint stimulation method and several classes of drug therapy, and wherein optical induction method curative effect is the most reliable, and is also comparatively convenient.Existing optical induction instrument one class is the mist visor, and its mist visor is static sighting target, can not realize moving forward and backward, and induces weak effect; Another kind of is the movably electronic control instrument of sighting target, and its sighting target moves and can not subjective control, and mobile range is excessive, and can not carry out individual operation, causes visual fatigue, dizziness etc. easily, and effect is induced in influence.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of simple in structure, use easy to operately, induce the good optical induction instrument for prevention and cure of myopia of prevention effect.
Optical induction instrument for prevention and cure of myopia described in the utility model, comprise eyepiece and sighting target, it is characterized in that having two look the tube be connected in the same rotating shaft by support, look an end of tube protruding eyepiece is installed, the other end is installed the sighting target eyeglass, two sighting target eyeglasses are inboard, and the sighting target eyeglass is arranged on the inner sleeve with identical picture sighting target, and inner sleeve is provided with the manipulation device that inner sleeve is vertically moved.
The similar telescope configuration, scientific and reasonable, during use, with the eye alignment eyepiece, facing to the bright place of light, to see sighting target clearly, regulating two spacings of looking tube overlaps two sighting targets fully, by manipulation device inner sleeve is moved forward and backward to sighting target is the clearest then and is degree, this moment sighting target the position we be referred to as near point, make inner sleeve reach by manipulation device again, sighting target is thickened be degree, this moment sighting target the position we be referred to as far point, so cycling moves back and forth sighting target and gets final product between near point and far point.
Prevent and treat principle:
Accommodative myopia is because the ophthalmic ciliary spasm causes, the patient only sees and just can see clearly when near when this moment, that is when in lens barrel, seeing sighting target clearly, only just can see clearly near point or nearer position, when sighting target is begun to blur by near point vision when far point moves, the patient only loosens to regulate and removes ciliary spasm and just can see sighting target clearly, so, the distance of sighting target is regulated in circulation, can induce the eyes ciliary muscle by spasm to loosening, thereby reach prevention, treat the purpose of accommodative myopia.
In this utility model:
Its inner sleeve is provided with the driving lever that inner sleeve is vertically moved, and driving lever passes the mobile notch of looking on the tube and is hinged on a nut, be hinged to be convenient to rotate to regulate, or axle is hinged, or the ball hinge etc., nut sleeve is contained on the screw rod, is fixed with adjusting knob on the screw rod.The turn knob, screw rod rotates, and drive nut moves, and the driving lever that is hinged on nut also moves thereupon, moves thereby drive inner sleeve.Simple in structure, easy to operate.
Two look the tube connecting axle and screw rod on same axis.Simple and compact for structure, use easy to operate.
This utility model is simple in structure, uses easy to operately, and the patient can and require according to self different characteristic arbitrarily to adjust, and comprises the amplitude adjusting sighting target and move, speed etc., induces prevention effect good, is convenient for carrying again, is beneficial to and applies.
Description of drawings
Fig. 1, this utility model one example structure sketch map.
Among the figure: 1,6, driving lever 2, screw rod 3, nut 4, look tube 5, sighting target eyeglass 7, driving lever shifting chute 8, inner sleeve 9, adjusting knob 10, look a connection support 11, protruding eyepiece 12, two is looked an articulated axle.
The specific embodiment
Below in conjunction with the embodiment accompanying drawing this utility model is further described.As shown in the figure, optical induction instrument for prevention and cure of myopia described in the utility model, comprise eyepiece 11 and sighting target, there are two to look tube 4 and be connected in the same rotating shaft 12 by support 10, look an end of tube 4 protruding eyepiece 11 is installed, the other end is installed sighting target eyeglass 5, two sighting target eyeglasses 5 are inboard with identical picture sighting target, sighting target eyeglass 5 is arranged on the inner sleeve 8, inner sleeve 8 is provided with the driving lever 1,6 that inner sleeve 8 is vertically moved, driving lever 6 passes the shifting chute of looking on the tube 47 and is hinged on a nut 3, and nut 3 is sleeved on the screw rod 2, is fixed with adjusting knob 9 on the screw rod 2; Two connecting axles 12 of looking tube and screw rod 2 are on same axis.
