Description

A kind of eye muscle training and look the Ophthalmological nursing apparatus of reinforcement far away

Technical field

This utility model relates to a kind of Ophthalmological nursing apparatus, particularly a kind of eye muscle training and look the Ophthalmological nursing apparatus of reinforcement far away.

Background technology

According to the physiological function characteristics of eyes, the needs of looking far, look nearly of eyes rely on the distance adjustment of dioptric focus to realize.On medical science physiology, eyeball is to have certain elastic cartilaginous tissue, the maintenance of its positive spheroid is the basis that guarantees cornea and crystal dioptric refraction back focus distance, that is to say, eyeball keeps its positive sphere-like, be to guarantee normal dioptric, the essential condition of the various low vision oculopathy that prevention true myopia, hypermetropia, astigmatism etc. cause because of ametropia.

The maintenance of the positive spheroid of eyeball is to be finished by the balanced tractive of six rectus around the eyeball.Actual in the eye process, such as the read-write of juvenile science trophophase, in the close eye, the Rectus muscle of its use mainly is the consolidation function that the tension of medial rectus realizes eyes; For another example, watch fixed targets such as TV, computer for a long time attentively, Rectus muscle can not obtain sufficient movement.These cause Rectus muscle unbalance to the tractive of augen with the eye custom, are to cause the eyeball distortion, cause hypermetropia and ametropia such as true myopia, astigmatism easily.

At the problems referred to above, existing caring instrument and method are mainly utilized electronics, medicine, magnetic therapy, thermotherapy etc., all there is certain defective, these methods are only alleviated the pathology that eye has taken place, and all can not be implemented in to carry out the initiative exercise of six Rectus muscles before pathology takes place and look reinforcement far away.Such as the long-distance runner, only the passive lower limb flesh massage by the health doctor can not bring up the long-distance running world champion, has only by secular active exercise of athlete self and training and just can practise strong physique.

Common eyesight testing table case only detects vision, belongs to diagnostic tool, there is no much meanings but move, train, look reinforcement far away, eye-care, vision care for eye muscle in the family.In addition, existing eyesight testing table case requires tester's distance far away, generally hangs on the wall and uses, and need other personnel to assist and can finish.Owing to be subjected to space, the very difficult enforcement of time restriction, its scope of application is very limited in the family.

Utility model content the purpose of this utility model is, a kind of eye muscle training is provided and looks the Ophthalmological nursing apparatus of reinforcement far away, overcome the deficiency of above-mentioned existing procucts and using method.Technical problem to be solved is: eye muscle is moved, trains, looks reinforcement far away and care device and eye chart case be incorporated into one, help user before and after examination of visual acuity, implement isostatic eye muscle training, look reinforcement far away and nursing, and can finish regular visual function and detect, realize that detection and initiative exercise prevent to carry out simultaneously.Second technical problem to be solved in the utility model is: by the warm control circuit of setting up temperature height fluctuations on this integration unit and the warm heater that relevant temperature just rises and falls, realize the warm nursing of bionical reason that eye is is just risen and fallen.

The technical scheme that its technical problem that solves this utility model adopts is as follows:

A kind of eye muscle training and look the Ophthalmological nursing apparatus of reinforcement far away, comprise casing, the front of casing is a panel, at the panel middle part eye chart is installed, at box house alphabetical backboard lamp is installed also, it is characterized in that: several Rectus muscle motion guidance lamps are installed on the panel diverse location, and these Rectus muscle motion guidance lamps are connected with the intravital control circuit of case respectively.

Described Rectus muscle motion guidance lamp is four, lays respectively on the line of adjacent straight angle point of the right angle electrical of rectangular panel and rectangular eye chart.

On casing, be respectively arranged with the speaker and the keypad that are connected with the intravital control circuit of case.

Also comprise by the intravital control circuit of control line and case be connected non-constant from high to low, the bionical warm nursing device that changes of temperature control from low to high.

Good effect of the present utility model also is:

(1), under the control of control circuit, the Rectus muscle motion guidance lamp that is positioned at four jiaos of casings lights in order, the user eyeball is followed the motion of bright lamp all the time, can need not the professional instruct under the purpose of six Rectus muscles of the self-service realization equalizing training of user.

(2), the speaker that is connected on this device control circuit can provide two kinds of acoustical signals, the beat auditory tone cues that first Rectus muscle motion guidance lamp is bright, go out not only can provide the prompting of eye muscle movement rhythm, and increase use enjoyment; It two is to be furnished with background music, such as the treatment music, plays and loosens neural effect.

(3), the design of the warm nursing of this utility model has outstanding substantive distinguishing features, it can realize the heat output of non-constant temperature, realize from high to low, automatic temperature-adjusting from low to high changes, imitated the physiological property of ocular angiogenesis smooth muscle contraction, help helping vascular smooth muscle when diastole, to increase blood vessel and include oxygen and enrich quantity of blood expressed, improve the aerobic metabolism of part tissue of eye, have additional nutrients; Vascular smooth muscle is when shrinking, and external temperature reduces synchronously, strengthens contraction intensity, with the powerful discharge of the venous blood of alluvial.The diastole contraction process of vascular smooth muscle helps eyeball interior tissue, eye muscle etc. to realize efficient blood circulation, for eyes provide abundant, prescribing adequate nutrition by the external physical intervention.

(4), needn't assist by other people, the daily people of user is self-service can to finish whole training, test, helps the cultivation with the teenager self-reliance.
