Description

A kind of portable pseudomyopia correcting instrument

Technical field

This utility model relates to a kind of ophtalmic treatments instrument, particularly to a kind of portable pseudomyopia correcting instrument.

Background technology

According to optical principle, extraneous object distance and the imaging in human eye from being inversely proportional to, the long-term close eye of people, the synchronization near reflex regulative mechanism of rationality of looking unfamiliar will be mobilized, being reacted by Diopter accommodation and complete or make up this process voluntarily, this process is medically called adjustment reaction. In this physiological adjustment course of reaction, human eye will occur that reflexive ciliary muscle contraction, refractive power strengthen, crystalline lens spheric curvature increases, the optical axis of two eyeballs converges elongation, pupil contraction etc. in succession. Regulate reaction by this series of physiological, quickly can not only form image clearly at retina, it is also possible to be imaged onto on the position that two eyes retinas are symmetrical. Then, by the photoreceptor cell��photosensory cell being felt activation, by neuro-vision path (depending on road), the information of imaging being transmitted to brain occipital lobe cortical visual centers, finally obtain stereopsis vision, the object at this time seen just can be fully aware of. But, the physiological reaction of this complexity is when regulatory mechanism runs into the destruction of various factors internal, external, such as long-term fatigue eye, cause adjustment anxiety and the spasm of ciliary muscle and eye socket periphery orbiculares, adjustment, the of a specified duration dioptric system that must change human eye can not be loosened during referring again to longer-distance object, cause ametropia, and destruction situation according to Diopter accommodation response system is different from degree, in succession suffer from heterogeneity, pseudomyopia in various degree.

Clinically, eyeball has inherent and external two groups of muscle, and inherent muscle is iris (sphincter pupillae) and ciliary muscle, the size of scalable pupil and lenticular focal length. External muscle has six, it is possible to control the rotation of eyeball.

In China's adolescent myopia rate about close to 70%, mainly see TV for a long time, online, play game to wait and do not note causing with eye, also have see the fault of written word, books put from eye cross close to, lighting condition bad etc., these all can make intraciliary muscle contracts last, crystalline lens F degree increases, making intraciliary muscle in tension, the crystalline lens becoming F can not be cherished and arrived normal condition again, thus causes pseudomyopia.

Before this, the common method rescuing pseudomyopia mainly has:

1, excimer laser operation for myopia, by cornea is cut, produces cornea flap, then takes laser action in cornea, reach to rescue ametropic purpose. excimer laser is a kind of wavelength invisible to the human eye only ultraviolet beam of 193 nanometers, its characteristic is that photon energy is big, wavelength is extremely short, the penetration power of tissue is extremely weak, ophthalmic will not be penetrated, only absorbed by tissue surface, surrounding tissue is lossless or damage atomic, excimer laser cornea refractive treatment technology (LASIK technology), it is that superficial keratectomy tissue is fabricated to a cornea flap with the base of a fruit by the miniature corneal lamellar diced system (abbreviation keratome) by a kind of special extremely precision, after upset cornea flap, under the control of the computer, the portion of tissue intending removing to the corneal stroma under lobe by excimer laser accurately gasifies, then in subcornea wash and by cornea flap reset, the form of anterior surface of cornea is changed with this, adjust the refractive power of cornea, enable ambient be converged on optical fundus exactly as, reach the purpose of correction of myopia, although the method for this cut-out cornea is quick, but eyes are existed certain damage, very risky.

2, eyeglass is rescued, Dai Jing is the modal method of child's correction of myopia, the principle joining mirror should be taked to make bathomorphic vision rescue the most low eyeglass of best vision equally, but the item that should be noted that is many, adhere to that the time is long, especially scarcely it may be noted that too much, produce a desired effect surely so also differing in loaded down with trivial details life.

Although excimer laser operation for myopia and eyeglass are rescued two kinds of methods and are attained by the purpose of correction of myopia at present, but all there is also certain defect.

Utility model content

The purpose of this utility model is in order to solve present stage, pseudomyopia treatment time is long, to shortcomings such as ocular damage are big, and the portable pseudomyopia correcting instrument of one proposed.

To achieve these goals, this utility model adopts the technical scheme that

A kind of portable pseudomyopia correcting instrument, it is characterized in that: include double shell, two through holes it are provided with in described double shell, cylinder between two described through holes from two eye distances of the mankind from corresponding, it is provided with a lining in one end of each described through hole, it is respectively provided on two sides with a fixing plate at the described double shell other end, each described fixing plate is all connected with a motor, the output shaft of each described motor is all socketed a sleeve, each described sleeve is equipped with a connecting plate, it is provided with baffle plate in the side of each described connecting plate, opposite side is provided with balancing weight, described baffle plate and corresponding through hole corresponding matching, the power supply powered to corresponding described motor it is all connected with in the downside of each described fixing plate.

On the basis of technique scheme, it is possible to have technical scheme further below:

Described double shell is also connected with one and tightens rope, described in tighten the two ends correspondence of rope and be connected to the both sides of described double shell.

Described power supply adopts aneroid battery.

The utility model has the advantage of: this device adopts physical method, can to the eyes of patient or simple eye carry out controlled sighting distance far and near distance location after, pass through Fast transforms, thus reaching the ciliary muscle (including controlling 6 muscle of periphery of eyeball) to controlling eyeball to carry out repetitious stimulation, to temper eyeball ciliary muscle, recover its function, muscle finally can be made to regulate the amount of curvature of eyeball optical axis length and spherome surface freely. Its simple in construction, easy to carry, it is possible to use at any time, result of use is good.
