Description

Health-care and treating instrument for amblyopia

This utility model belongs to ophthalmology medical science and kaleidoscope field, relates to the instrument and the kaleidoscope of a kind of amblyopia health care and treatment.

The kaleidoscope of inventing before more than 100 years for the public is known mostly is equipped with colored cullet in cylindrical shell, plastic flakes, and rotating cylinder can be watched different images.Designer of the present utility model once announced a kind of CN89215916's " music electronic kaleidoscope ", it replaces colored cullet and plastic flakes with electronic circuit and light-emitting component, when luminescent device is luminous, can watch the electronic color picture, make ancient kaleidoscope playback extraordinary splendor, but this kaleidoscope only is a toy of viewing and admiring amusement as a kind of.

Amblyopia is a kind of visual disorder that is caused by multiple reason, generally can't correct with the method for joining mirror.The method of preventing and treating amblyopia at present is more, and is wherein comparatively simple with the red flare therapy, is easy to promote.Designer of the present utility model once announced CN90202156 and CN94212912's " electronic kaleidoscope for amblyopia therapy ", it is restricted to the light source of kaleidoscope inner light source group the flicker HONGGUANG of certain light intensity and frequency, by direct stimulation to its responsive macula retinae district, make its excitement, thereby reach the purpose of treatment.This invention has solved the amblyopia instrument technically and has involved great expense, and the amblyopia disease is difficult to the difficult problem of early discovery and this long-term puzzlement medical profession of early treatment, provides a kind of treatment and health care instrument for the amblyopia control enters family.In addition, also have some to adopt the therapeutic equipments of red flare principle design, as: CN86200467, CN88217622 etc., the basis of its treatment is all with the red light sensitiveness of pyramidal cell in the macula retinae district to 620～700nm (nanometer) wavelength, by photostimulation, improve sensation input and critical fusion frequency, pupillary reflex is brought out in utilization flash of light simultaneously and crystal is regulated, thereby reaches the purpose of taking exercise and improving vision.The treatment theoretical foundation and the method thereof of above-mentioned all these instruments have all been ignored three kinds of basic color vision sensors of the interior existence of eyes of people, that is have been had the retinal cones somatic cell of experiencing HONGGUANG, green glow and blue light specially respectively.Modern visual electro-physiology and colour vision studies have shown that: above-mentioned three types pyramidal cell is respectively to the indigo plant of 430～475nm, 520～570nm and 620～700nm, green, red light sensitiveness and excitement; In addition, according to the electrophysiologic studies achievement of vision, visual stimulus to bring out current potential (VEP) relevant with Strength Changes, frequency and frequency change, flashlight images and image change with the intensity of photostimulation.Experiment shows: the light of change intensity and change frequency is caused to bring out potentiometric response greater than the potentiometric response that brings out under fixedly light intensity and the fixed frequency condition; The pictorial stimulus of flash of light causes and brings out the bring out potentiometric response of potentiometric response greater than simple uniform luminance stimulation, what flash of light changed pictorial stimulus brings out the bring out potentiometric response of potentiometric response greater than simple flash of light figure, the contrast of figure sight is big bring out potentiometric response greater than the contrast of figure sight little bring out potentiometric response.And above-described therapeutic equipments mostly all is to adopt fixed light intensity and fixed flicker frequency and simple uniform luminance stimulating method, and this compares with the achievement in research of modern visual electro-physiology and seems and fall behind and not enough, thereby hinders the further raising of curative effect.

The purpose of this utility model is to provide a kind of improved health-care and treating instrument for amblyopia, it adopts many class frequencys and light intensity to be respectively 1～60Hz (hertz) and 30～200mcd (milli candela), peak wavelength is respectively 620～680nm (nanometer), 520～570nm and 430～475nm are arranged in the red of figure according to the order of sequence, green, blue luminescent device group is as radiation source, multichannel output by the flicker control circuit changes and multiple frequency change, produce light intensity, frequency, wavelength and variable passage of scintillation light and the scintigram picture of image, stimulate and the three kinds of dissimilar pyramidal cells in exercise macula retinae district, improve conduction function, improve the sensitivity threshold of dissimilar optic cells to special wavelength light, improve the sensation input and the critical fusion frequency of eye, improve curative effect, thereby overcome the deficiency of above-mentioned Therapeutic Method and instrument.

The purpose of this utility model is achieved in that in the hollow cylinder that front end connects, the protecgulum of watching the hole that is provided with that front end with it is connected is arranged, be positioned at cylinder back-end along its centrage the flicker control circuit is installed successively, be furnished with the circuit board of luminescent device group and place reflecting mirror group between luminescent device group and the protecgulum, flicker control circuit wherein is program control and audio frequency control flashing circuit, it is by rectification amplifier, voltage controlled oscillator, pulsqe distributor, multichannel output driving circuit and composite audio generator are formed, wherein the audio output of composite audio generator connects rectification amplifier, every road drive end of multichannel output driving circuit is connected with one group of homochromy luminescent device respectively, the luminescent device group is red by several respectively, green, blue light emitting diode pipe group is formed, and its frequency and light intensity are respectively 1～60Hz (hertz) and 30～200mcd (milli candela).When flicker control circuit control multi-group light-emitting device during at the orderly light-emitting flash in different positions, by the multiple reflection of reflecting mirror group, is seen the stereoscopic picture plane of color and change in pattern from watching Kong Zhongke with the frequency programs set and composite audio frequency.This continuous variation wavelength, the passage of scintillation light of frequency and the pattern of alternate constantly stimulate the human eye retina, can reduce the adaptability of optic nerve to passage of scintillation light and flicker image, activate better that absorption spectrum is red in the macula retinae district, green, three types blue pyramidal cell also makes it excited, improve the sensitivity threshold of optic cell to special wavelength light, thereby improve conduction function, improve sensation input and critical fusion frequency, photostimulation simultaneously also can be brought out pupillary reflex and crystal and regulate, not only can temper vision and prevent and treat amblyopia, but also can improve the modulability visual disorder, also can improve effect of amblyopia simultaneously and shorten treatment cycle.
