Abstract

The utility model relates to a myopia therapeutic apparatus for youngsters, which belongs to equipment for curing eyes. The existing therapeutic apparatus which can generate red laser has the insufficiency of nonideal therapeutic effect, complicated structure, high cost, inconvenient popularization and popularity, etc. in different degrees. The therapeutic apparatus of the utility model is composed of an electrical control box, a lamp shade, a bulb, a viewing screen, etc., and is characterized in that the viewing screen is provided with replaceable therapeutic cards under the background of the red laser. Simultaneously, the red laser conducts the successively repeated variation of brightening-getting dark-turning off. Patients can change different therapeutic cards according to the situations of eyesight, and the visual training can be conducted. The therapeutic apparatus can overcome the insufficiency of impaired concentration of the patients, and thus the therapeutic effect can be improved. The utility model which can be widely used in a hospital, a clinic, a school, a household has the advantages of good therapeutic effect, stable effect, less rebound, safety, low cost, simple and convenient operation, easy maintenance, etc. The utility model is mainly used for straightening myopia and amblyopia of youngsters, and simultaneously, the utility model is good for relieving asthenopia, etc. of adults.

Description

The adolescent myopia therapeutic instrument

Technical field

This utility model relates to the improvement of therapeutic instrument for shortsightedness, especially for the adolescent myopia therapeutic instrument of correcting adolescent myopia, amblyopia, belongs to the equipment of treatment eyes.

Background technology

The therapeutic equipments that is used to correct adolescent myopia, amblyopia at present is many, particularly can produce the therapeutic instrument of the nano red light of wavelength 620-700, stimulates the pyramidal cell at eyes macula retinae center with red light, reaches the purpose of treatment myopia, amblyopia.As Chinese patent 87211854.1 etc., but exist in various degree all in the therapeutic process that patient's difficult concentrating curative effect is undesirable, complex structure, cost height, deficiency such as be unfavorable for popularizing.

Summary of the invention

The purpose of this utility model provides that a kind of therapeutic effect is good, cost is low, easy to use, the adolescent myopia therapeutic instrument that is easy to apply.

The technical scheme that realizes this utility model purpose is: this adolescent myopia therapeutic instrument, comprise lampshade, bulb, the film viewing screen that on lampshade, has the nano red optical filter of wavelength 620-700, electric control box, it is characterized in that before film viewing screen, having the inserted sheet frame, insert the treatment card of inserted sheet frame; Oscillating circuit in electric control box is electrically connected with bulb.

The treatment card is to have the eyesight testing symbol of black and the word that is complementary with the eyesight testing symbol size, figure, symbol on slide.The brightness of oscillating circuit control bulb is " bright-gradually dark-as to go out " and changes continuously, the time ratio of " bright-dark " and " going out " for 1-20 second than 1 second.

This utility model is simple in structure, oscillating circuit control bulb brightness changes, make to produce brightness on the film viewing screen of therapeutic instrument and be the red light that " bright-gradually dark-as to go out " changes wavelength 620-700 nanometer, before the red light film viewing screen, can change different treatment cards according to patient's myopic degree.The patient notes watching black eyesight testing symbol on the red background, word, figure, symbol etc. under dark room conditions, can overcoming in the past, therapeutic instrument has only HONGGUANG not watch the deficiency of target patient difficult concentrating, the visual training of adjusting repeatedly through certain hour, can progressively improve patient's vision, thereby improve therapeutic effect.

The utlity model has that therapeutic effect is good, the effect stability bounce-back less, safe and reliable, cost is low, easy to use, for ease of maintenaince, advantage such as can in hospital, clinic, school, family, be extensive use of.Be mainly used in and correct teen-age myopia, amblyopia, also beneficial to removing adult's asthenopia etc. simultaneously.

Description of drawings

Accompanying drawing 1 is the structural representation of a kind of embodiment of this utility model.Fig. 2 is the structural representation that A partly inserts the inserted sheet frame among Fig. 1 to the treatment card.Fig. 3 is the electric circuit diagram of a kind of embodiment of this utility model.Fig. 4 is the variation sketch map of bulb side voltage among Fig. 3.Among the figure: 1 electric control box, 2 fluorescent tubes, 3 lampshades, 4 switches, 5 circuit boards, 6 transformators, 7 attaching plugs, 8 bulbs, 9 film viewing screens, 10 inserted sheet frames, 11 treatment cards, 12 eyesight testing symbols, 13 words, figure, symbol, 14 lamp sockets.

The specific embodiment

This utility model is described further with the embodiment that provides below in conjunction with accompanying drawing.

With reference to Fig. 1,2, this adolescent myopia therapeutic instrument is to be connected with snakelike fluorescent tube 2 on electric control box 1, and lampshade 3 is housed on snakelike fluorescent tube, and circuit board 5, transformator 6 etc. are housed in electric control box, and the oscillating circuit on the circuit board is electrically connected with bulb 8.Be equipped with by the film viewing screen 9 that has red optical filtering film to constitute in lampshade the place ahead, before film viewing screen, have inserted sheet frame 10, in the inserted sheet frame, be inserted with removable treatment card 11.Treatment be printed on the card black eyesight testing symbol 12 and with word, figure, the symbol 13 of the identical size of eyesight testing symbol.The treatment card is divided into seven by 0.4,0.5,0.6,0.8,1.0,1.2,1.5 different visual standardses.Word, figure, symbol on the treatment card can be selected multiple pattern, to strengthen the interest of children in treatment.

Electric control circuit is made up of circuit such as transformation, rectification, vibrations as shown in Figure 3, and oscillating circuit output is " V at the voltage of bulb side ₁6 volts → V ₂3.8 volt → V ₀O volt " continuous variation, V ₁To V ₂Time T ₁Be 8 seconds, V ₂To V ₀Time T ₂Be 1 second (with reference to Fig. 4); K closes a switch ₂After, T ₁Be 13 seconds, T ₂It is 1 second.Make on the film viewing screen " bright-gradually dark-as to go out " the continually varying HONGGUANG that produces different frequency, the time ratio of " bright-dark " and " going out " be 8 seconds than 1 second and 13 seconds ratios 1 second.Also can select for use other oscillating circuits to reach this utility model purpose.

Using method: under dark room conditions, opening therapeutic instrument, according to the patient's vision situation, is 0.4 as patient's vision, before the treatment card of selection 0.4 inserts film viewing screen.

The patient is generally apart from about 3 meters of film viewing screens, also can adjust distance according to the vision situation, the patient notes watching the black eyesight testing symbol that changes on the treatment card that red light is a background, word, figure, symbol etc. during treatment, once only see one, concentrate one's energy to see, to see clearly is target, and had a rest nictation when HONGGUANG was gone out.Through visual training repeatedly, vision as reaches 0.5 if any raising after the optometry, changes 0.5 treatment card again, continues training, until rehabilitation.Treatment was a course of treatment with 12 days, treated every day 5-8 minute.
