Abstract
The invention discloses therapeutic apparatus for an ocular part, in particular to therapeutic apparatus for adjusting diseases of ametropia of the ocular part such as myopia and hyperopia. The therapeutic apparatus for myopic eye comprises a model sucker (1) provided with an air passage, the front end of which is matched with an eyeball, a rubber hose (2) connected with the model sucker (1), and a negative pressure source (3) connected with the rubber hose (2). The apparatus causes the model sucker to communicate with the negative pressure source through the rubber hose; when the model sucker is aimed at and in contact with a retina, the model sucker sucks a cornea under the action of the negative pressure source; model sucking can cause the cornea to be subject to sucking deformation for a short time; and the cornea is caused to become a slight perpetual deformation during repeated deformation. As approved by clinic trial over the years, the apparatus can well correct ametropia of the ocular part such as myopia and hyperopia, has good therapeutic effects, and is particular effective for teenagers. The apparatus has the beneficial effects of simple and convenient operation, simple structure, low cost, safety, reliability and no side effect.
Description
Technical field
The present invention relates to a kind of eye treatment instrument, relate in particular to eye ametropia treatment of diseases instrument such as a kind of adjusting myopia, hypermetropia.
Background technology
Now human along with development of science and technology, need the knowledge of study more and more, and because the appearance of computer, more increased the burden of eyes, people often read a book and use computer, time to grow eyes and produce regular fatigue, make hypometropia in the course of time; Older old man has some hypermetropias, and these all are that variation has taken place for organ in the eyes, make the eyes cisco unity malfunction.Treatment myopia at present, presbyopic method have following several mode: a kind of is to adopt external used medicine to treat, and this kind method can only be alleviated the related symptoms of disease such as myopia and can not reach the purpose of healing; Be to adopt cornea to put to cut operation and excimer laser treatment method in addition, principle all is the radius of curvature that changes cornea, but above-mentioned two kinds of methods have brought damage for people's cornea, and medical expense height, make its popularization be subjected to certain restriction, if and these two kinds of Therapeutic Method also exist recurrence once more, the problem that can not treat once more.
Summary of the invention
The invention provides a kind of apparatus for treating myopia in order to solve the problems of the technologies described above, purpose is to cure eye ametropia diseases such as myopia, hypermetropia under the prerequisite of not damaging cornea, makes eyes recover normal condition, and it is simple in structure, and therapeutic effect is good.
To achieve these goals, the present invention is achieved in that a kind of apparatus for treating myopia, and it is to be made of the mould suction nozzle 1 that is provided with air duct of front end and eyeball coupling, the sebific duct 2 that is connected with mould suction nozzle 1, the negative pressure source 3 that is connected with sebific duct 2.
The structure of described mould suction nozzle 1 is: its anterior for the suction nozzle 4 of the interior concave spherical surface of eyeball coupling, the rear portion is the connector 5 that is connected with suction nozzle 4, in the middle of the connector 5 is hollow channel 7, offers air duct 6 on the suction nozzle 4, and this air duct 6 is connected with the hollow channel 7 of connector.
The structure of described mould suction nozzle 1 is: its end is the interior concave spherical surface that mates with eyeball, sphere is provided with air duct 6, its rear end is the mould suction nozzle body 8 that is provided with hollow channel 7, and mould suction nozzle body 8 is an integral structure with interior concave spherical surface, and air duct 6 is connected with middle gas passage 7.
Described mould suction nozzle 1 is to be made through mold pressing by transparent flexible material.
Described negative pressure source 3 for can provide-0.01～-the adjustable negative-pressure source of 0.08Mpa pressure.
Characteristics of the present invention and effect are as follows:
The present invention communicates through sebific duct the mould suction nozzle with negative pressure source, when the mould suction nozzle was aimed at cornea and is in contact with it, under the effect of negative pressure, the mould suction nozzle just held cornea, shape by selected mould suction nozzle sucks, set the time inwardly close source of the gas and finish the seance running; The mould suction can make cornea do the attraction distortion of short time, repeatedly will make cornea that a little permanent deformation is arranged in the deformation at this, confirm through clinical trial for many years, it can treat eye ametropia diseases such as myopia, hypermetropia preferably, therapeutic effect is good, especially particularly effective to teenager, its operational approach is easy, and therapeutic instrument is simple in structure, cost is very low, safe and reliable, have no side effect.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail, but protection scope of the present invention is not limit by embodiment.
Embodiment one:
As depicted in figs. 1 and 2, the structure of apparatus for treating myopia of the present invention is as follows: it is to be made of the mould suction nozzle 1 that is provided with air duct of front end and eyeball coupling, the sebific duct 2 that is connected with mould suction nozzle 1, the negative pressure source 3 that is connected with sebific duct 2.Wherein the structure of mould suction nozzle 1 is: its anterior for the suction nozzle 4 of the interior concave spherical surface of eyeball coupling, the rear portion is the connector 5 that is connected with suction nozzle 4, in the middle of the connector 5 is hollow channel 7, and suction nozzle 4 is provided with air duct 6, and this air duct 6 is connected with the hollow channel 7 of connector.R shape in the mould suction nozzle 1 when Fig. 2 is the treatment myopia, its indent spherical radius R forms the attraction deflection of t value greater than patient's cornea real radius, and the size of t value and the time length of attraction are according to patient's eyeball deformation state decision.Therefore indent spherical radius R can make multiple size according to patient's myopic degree.Air duct 6 can be the straight hole passage, also can be the inclined hole passage.
