It is characterized in that two lens turntables (22) controlled by two lens rotation adjusting handwheels (4) are uniformly distributed with OD, +1.25D, +2.25D, 10ΔSeven lenses of +4.25D, +5.25D and black sheet are placed in a dark box (3) and are attached with other devices to carry out screening on the amblyopia of the children. The method has the advantages of high checking speed, high accuracy, high cooperation rate of infants, safety and reliability.
Description
This utility model relates to a kind of medical domain, be used for objective children's myopia using examination dynamically close picture children's myopia using screening instrument.
The objective determination method of more advanced screening children's myopia using and instrument have 1. visual evoked potential (VEP) in the prior art, 2. select to watch method (PL), 3. Grating Modulation transfer function (MTF), 4. optokinetic nystagmus (OKN), 5. cycloplegia skiametry etc.Though these inspection methods and instrument have his own strong points, its shortcoming is as follows: 1. instrument complexity, cost an arm and a leg, and basic unit is difficult to purchase.2. detection difficulty is big, complicated operation, and the grass-roots work personnel are difficult for grasping.3. sense cycle is long, the expense height, and the child and the head of a family are difficult for accepting.4. volume weighs greatly, carries inconvenience, is unwell to the examination of basic unit's amblyopia.Auxiliary facilities and conditions such as the need screened room that 5. has, air-conditioning are not suitable for the national conditions of China, are difficult to popularize.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of picture children's myopia using screening instrument that dynamically closes is provided, and to guarantee the normal development of China and the child of developing country visual function, improves this national visual function quality.
Technical solution of the present utility model is: two lens slewing discs (22) that rotate adjusting handles (4) control by two eyeglasses go up uniform OD (zero degree) ,+1.25D (positive 1.25 degree) ,+2.25D, 10
Δ(prisms of 10 degree) ,+4.25D ,+5.25D and seven eyeglasses of black-film (25), place in the camera bellows (3), replace traditional big darkroom, realize miniature.And attached with: place skiascope horizontal slip plate (18), observation port (2) in the chute on camera bellows (3) sidewall; Connect be equipped with on it two close image pattern (24) bent axle close picture adjusting handle (5), this song wheel and moving image (19) also place in the camera bellows (3); Two eyeglasses that connect lens slewing disc (22) rotate adjusting handle (4); The screw thread of two symmetries and camera bellows (3) sidewall is spirally connected, two optical center adjusting handles (6) that its other end is connected with optical center adjusting slider (23) in placing chute; Add electrical appliance part (9) and lifting, stationary fixture, the examinate is in the one side of camera bellows (3), and the medical worker can implement dynamically to close picture children's myopia using screening on its opposite.
This utility model has following advantage compared to existing technology:
1, be a kind of objective, holographic, multi-functional amblyopia screening apparatus: what its reflected is a holography, spatial, dynamic overall process.It can diagnose the oculopathy of external eyes, refractive media, macula lutea function and refractive status etc.It can examination go out the different amblyopia of five classes, is that of amblyopia examination technology innovates and breaks through.
2, inspection speed is fast, the accuracy height: eye of examination in seconds, its accuracy rate is 96%.
3, the child checks the cooperative rate height to using this instrument: owing to this instrument employing sound, light, moving colored inducement signal, be imbued with interest, 2-6 years old children's cooperative rate is 98%.
4, safe and reliable: as to use the inspection of this instrument, need not darkroom and mydriasis, so nontoxic, harmless, pantaphobia are easily accepted by the child and the head of a family thereof.
5, volume is little, and is in light weight, and portable band is simple to operate, easily grasps, and especially is suitable for basic unit the screening of children's myopia using is used.
6, this instrument is simple in structure, and is cheap, the profit height.Use this instrument only the child of 2-3 kindergartens to be carried out examination. be recoverable fully invested.So be easy to apply.Face China 400,000,000 children's task to be looked into, vast market and considerable economic will be arranged.
7, " the Polaroid children's myopia using photographic apparatus " succeeded in developing before this instrument and the inventor reaches " dynamically induced logarithm test chart for children " and is used in combination, can constitute the children's myopia using screening system of a perfect in shape and function and enter the international market, be 2,000,000,000 world children services, especially be the child of developing country service.
