Description

A kind of visual physiological recuperating instrument

Technical field

This utility model relates to armarium, and more particularly, this utility model relates to a kind of visual physiological recuperating instrument.

Background technology

In the prior art, the visual rehabilitation instrument adopts traditional photoelectric technology, use equipment such as CAM instrument, red flare instrument, synoptophore, all there is different shortcomings in these equipment, for example: CAM instrument bar grid stimulus intensity is lower, and need keep the corresponding relation of treatment eye and turn bar grid in the therapeutic process by fine manipulation projects such as tracings, the moderate and severe degree of amblyopia patient of, hand-eye coordination ability lower for vision, the comparison difficulty operates, simultaneously because training method is single, lack interest, the infant compliance is poor.Red flare instrument stimulation mode commonly used is single, and the source stimulating of single wavelength can only cause the electrical activity of part cone cell, and therapeutical effect is limited.Synoptophore treatment amblyopia, mainly utilize the Hai Dinggeshi brush and put the flicker derepression technological means realization of going out, in the therapeutic process, the autonomous cooperation of infant is had relatively high expectations, often all lack the most basic captivation for child patient, and difficulty is played its effect owing to its form of therapy.Above-mentioned three kinds of modes are watched the type amblyopia attentively for lower non-central of vision and are had little effect.Though traditional after image pleoptics can improve this type of amblyopia patient's vision effectively, once voguish the fifties in last century, the optical fundus that this therapy utilizes the after image mirror to throw according to the amblyopia eye forms positive after image, change negative afterimage subsequently, under after image transforms, the inhibition that is not suppressed the central fovea of macula of sexual stimulus is disengaged and is in excitatory state, and it experiences that function is corresponding to be strengthened under induction.After after image forms, make the patient watch black " ten " sighting target under the white background attentively, by " training is looked at eye-hands-cerebral cortex joint space perception and center admittedly ", off-centre is watched attentively change central fixation into, and then be improved the vision of amblyopia eye.In this therapy implementation process, the reinforcement of artificial after image formation, after image and maintenance and on this basis " training is looked at eye-hands-cerebral cortex joint space perception and center admittedly " are the key links of treatment.Difficult point is that patient's treatment eye keeps stable corresponding relation with " ten " center, and repeats " training is looked at eye-hands-cerebral cortex joint space perception and center admittedly " action accurately and efficiently on this basis (this action realizes with spillikin click " ten " center in classical pleoptics).There is following defective in tradition " after image increase look treatment ":

1. the patient notices that object (" ten " center) lacks variation in form, and is uninteresting, is difficult for attracts attention, and infant is reluctant to cooperate;

2. " training is looked at eye-hands-cerebral cortex joint space perception and center admittedly " owing to lack technology control device and quantizating index for action accuracy, and make it to become a mere formality.Simultaneously, owing to the covert invalid noise that causes that knocks forms pessimal stimulation to cental system;

3. lack effective auditory stimulus hands section;

4. the whole training process time is manually " control ", time and effort consuming, and efficient is extremely low and be prone to mistake.

Above-mentioned defective is all directly having influence on curative effect in varying degrees.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming that prior art exists, in conjunction with modern visual physiology achievement in research, at light, sound,, on the technological layer of digital control, allow the patient look training action admittedly by eye-hands-cerebral cortex joint space perception and center, with of the direct stimulation of feature light source for vision, indirect stimulation for visual cortex organically combines with acoustical signal, the synchronization activity of the cortical cell of amblyopia eye input is strengthened, thereby remove the inhibition of vision in the cerebral cortex level, promote visual development, the final effectively treatment amblyopia that realizes.This utility model is a kind of safe, reliable, eutherapeutic amblyopia treatment instrument, especially watches type attentively and other refractory type amblyopia has the therapeutic effect that obviously is better than other method for non-central.This instrument both can improve curative effect greatly, can improve medical worker's working condition again, increased work efficiency.

The purpose of this utility model is achieved in that

Its special character of a kind of visual physiological recuperating instrument is, connects institute by photoelectric sensor, cycle timer, color translator, voice operated controls, photoelectric counter and single-chip microcomputer etc. by circuit and forms.

Described photoelectric sensor is to receive audion, time base circuit, logic circuit and discrete device by infrarede emitting diode, photoelectricity to constitute; Described cycle timer is to be made of single-chip microcomputer and circuit, is used to control treatment time and treatment time at interval; Described color converter is to be made of D/A change-over circuit, four color luminescence units, discrete device, is used for color, brightness and the flashing rate of conversion luminescent device; Described voice operated controls is to be made of single-chip microcomputer, memorizer, D/A conversion and audio amplifier circuit, is used for playing music or prompt tone in good time; It is to be made of decoder driver circuit, group of four figures tube device that described photoelectrometer shows numeroscope, is used for record and final the demonstration when time effective hits of treatment overall process patient;

The advantage that this utility model compared with prior art has is:

In conjunction with modern visual physiology achievement in research, on the technological layer of light, sound, electricity, digital control, allow the patient look training action admittedly by eye-hands-cerebral cortex joint space perception and center, indirect stimulation for visual cortex organically combines for the direct stimulation of vision and acoustical signal with the feature light source, the synchronization activity of the cortical cell of amblyopia eye input is strengthened, thereby remove the inhibition of vision in the cerebral cortex level, promote visual development, the final effectively treatment amblyopia that realizes.Clinical observation more than 2 years shows that this instrument is a kind of safe, reliable, eutherapeutic amblyopia treatment equipment, especially watches type attentively and other refractory type amblyopia has the therapeutic effect that obviously is better than miscellaneous equipment for non-central.This instrument both can improve curative effect greatly, can improve medical worker's working condition again, increased work efficiency.
