Abstract

The utility model relates to an amblyopia therapeutic apparatus with a yellow backlight source. Currently, more and more children have amblyopia phenomena. A CAM (Complementary and Alternative Medicine) vision stimulation instrument adopts a blue and white bar grid as a vision stimulation source and has strong contrast sensitivity, and has obvious effects to hyperopic amblyopia children but is not useful for myopia amblyopia children, can cause increase of shortsightedness degrees. The amblyopia therapeutic apparatus with the yellow backlight source which is provided by the utility model can overcome the defects in the prior art. According to the technical scheme provided by the utility model, the amblyopia therapeutic apparatus with the yellow backlight source comprises a host; the host is provided with an operation surface, a picture disc shell and a rotatable base plate inner column; the picture disc shell is internally provided with the blue and white bar grid capable of rotating along the base plate inner column; the blue and white bar grid is provided with a picture drawing plate; a light source is arranged below the blue and white bar grid; and the light source is a yellow backlight source. The amblyopia therapeutic apparatus disclosed by the utility model has the obvious effects to the hyperopic amblyopia children, can prevent the development of myopia and has very good curative effects on myopia amblyopia.

Description

A kind of yellow backlight amblyopia therapeutic equipment

Technical field

This utility model belongs to ophthalmic medical instrument, is specifically related to a kind of yellow backlight amblyopia therapeutic equipment.

Background technology

At present, the phenomenon of children's myopia using is more and more.People find that in examination of visual electro physiology brain visual cortex maincenter has contrast sensitivity highly to spatial frequency, and spatial frequency is more high, and more energy stimulating visual cortex maincenter cell makes its activity increased response.Because spatial frequency is just representing the height of visual function, so in close relations with amblyopia.CAM looks the stimulation instrument, makes of the blue informal voucher grid of different frequency and looks stimulus, makes the amblyopia eye both be subjected to the stimulation of different space frequency on each orientation, and the grating that is subjected to contrast again stimulates, and visual center cell is strengthened grow and the raising vision.

The blue informal voucher grid of original technology do that to look the stimulus contrast sensitivity strong, at hypermetropia children with amblyopia effect obviously and just impracticable to the myopia children with amblyopia, increase the growth of the near-sighted number of degrees easily.

The utility model content

The purpose of this utility model provides a kind of yellow backlight amblyopia therapeutic equipment, and is not only obvious at hypermetropia children with amblyopia effect, and the development of myopia prevention in advance, and at the myopia amblyopia better curative effect arranged.

The technical solution adopted in the utility model is as follows:

A kind of yellow backlight amblyopia therapeutic equipment, comprise main frame, setting operation face on the main frame, draw disk casing and rotatable chassis inner prop, drawing the interior setting of disk casing can be with the blue informal voucher grid of chassis inner prop rotation, arrange on the blue informal voucher grid and draw dish, its special character is: under the described blue informal voucher grid light source is set, light source is yellow backlight.

The above-mentioned dish of drawing is the transparent plastic disk.

The above-mentioned inner surface of the drawing dish picture that has been sticked is drawn dish and is arranged on the picture disk casing.

The center of above-mentioned picture arranges the picture centre bore, and picture is the plastic sheet that is printed on pattern.

This utility model adopts gold-tinted as light source, gold-tinted is 550 nanometer reflectance spectrums, be near the light source of available light, available light is best suited for the light source of eyes, the gold-tinted irradiation is even, soft, be not easy to cause eyestrain, it also is the sensitivity spectrum of vision, be the most acceptant light of eyes, be that eyestrain is minimum, this utility model both can be subjected to contrast for the myopia amblyopia grating stimulates, and visual center cell is strengthened grow to improve vision, the development of myopia prevention in advance has better curative effect at the myopia amblyopia again.

Description of drawings

Fig. 1 is this utility model structural representation;

Wherein, 1 is operating surface; 2 is light source; 3 is the chassis inner prop; 4 is the picture disk casing; 5 is main frame; 6 for drawing dish; 7 is the blue bar grid; 8 is the picture centre bore.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is elaborated:

Referring to Fig. 1, a kind of yellow backlight amblyopia therapeutic equipment, comprise main frame 5, setting operation face 1 on the main frame 5, draw disk casing 4 and rotatable chassis inner prop 3, drawing disk casing 4 interior settings can arrange on the blue informal voucher grid 7 and draw dish 6 with the blue informal voucher grid 7 of chassis inner prop rotation, it is characterized in that: described blue informal voucher grid arrange light source 27 times, and light source 2 is yellow backlight.

Draw dish 6 for the transparent plastic disk, the inner surface of drawing dish 6 picture that has been sticked is drawn dish 6 and is arranged on the picture disk casing 4.The center of picture arranges picture centre bore 8, and picture is the plastic sheet that is printed on pattern.

The adjusting button is set, the pulse display lamp on the operating surface 1.

Operation instruction is as follows:

1, by erection sequence with blue bar grid 7, picture and draw dish and 6 install, during installation, picture is stained with clear water, be attached on the inner surface of drawing dish 6, blue bar grid 7 are installed on the chassis inner prop 3 by the hole at center, draw dish and are loaded on blue bar grid 7 tops, are ready to watercolor pencil.

2, the plug that plugs in, " power supply " display lamp is bright.It is bright to the required time display lamp to press " selection " key, begins training by "start" button.3, blue bar grid 7 begin to rotate.

4, draw along the picture pattern transparent drawing on the dish, infant should be sat up straight during training, and eyes are far away apart from instrument one chi.5, when training requires the patient to hide strong eye, and the eyes amblyopia patient can train simultaneously, differs big (the above person of two row) as the eyes refractive diopter and should alternately hide training.6, the patient is under visual stimulus, and the pattern of depicting is consistent with the pattern on the picture, illustrates that training is correct.7, training finishes, and will draw the dish wiped clean with moist rag, in order to using next time.8, pattern should often change to improve patient's interest.Blue informal voucher grid should be trained from the thickest bar grid, along with the raising of vision, change thinner bar grid.9, also can use trace paper instead and overlay on and draw on the dish, use watercolor pencil to describe pattern.

10, the training time is controlled automatically by intervalometer, and the time is to stopping automatically.

11, to finish training in advance, press " power supply " key.Display lamp extinguishes, and disk stops operating.

Clinical result of use case sees Table 1.

Table 1, clinical result of use case

More than clinical result of use case show that this utility model has better curative effect at the myopia amblyopia.
