Abstract

The utility model relates to a treating apparatus for amblyopia in color and light. The utility model adopts a rotary picture mechanism which is composed of a rotary disc and a driving device to cause the traditional treatment to be free from the aridity to enhance the treating interest of the sick children. The utility model has timing control for installation, and cycle control for the work, which is especially convenient to operate. The utility model has short treating period, and reliable curative effect, and is ideal dual-purpose treating apparatus for amblyopia in the hospital and family.

Description

Rotary picture type treating apparatus for amblyopia in colour and light

This utility model is a kind of amblyopia therapeutic equipment, belongs to medical mechanical domain.

Amblyopia is a kind of common eye diseases in children.According to units concerned's investigation statistics, its sickness rate average out to 3.5% of nationwide, some areas are up to 5%.In order to improve nation's quality, make thousands upon thousands children with amblyopia break away from the body and mind misery, eliminate the inconvenience that aspects such as study that amblyopia is given them, life are brought, people have developed many amblyopia therapeutic equipments according to the origin cause of formation of amblyopia.The therapeutic instrument that is extensively adopted by each hospital--flicker amblyopia therapeutic equipment, its mechanism are the pyramidal cells that stimulates the sharpest macula lutea center of human eye vision by HONGGUANG, make pyramidal cell restore funcitons gradually at present, thereby improve central vision.General each treatment all will have several groups of repetitive therapy, and every group of treatment time reaches tens minutes.Staring at one like this for a long time and have no intereting flicker red light, is the uninteresting thing of part after all, and infant is divert one's attention unavoidably.Influence therapeutic effect, no matter increased the course of treatment and, the infant heart is also suffered untold misery.

The purpose of this utility model is to design a kind ofly takes like a shot for the amblyopia infant, and the hospital that has no side effect, home-use amblyopia therapeutic equipment are in order to overcome deficiencies such as the traditional amblyopia treatment length course of treatment, weak curative effect.

This utility model is to realize its purpose like this.

A kind of rotary picture chip chromatelopsia theuparatic apparatus, by the picture rotating mechanism, red-light source part and camera lens part are grouped into, it is characterized in that: be positioned at the intermediary picture rotating mechanism of housing and include rotating disk 5, be fixed on the ratchet 25 in the rotating shaft 24 of rotating disk 5, reach the sour jujube that is complementary with ratchet 25 and grab 9, grab 9 with sour jujube and slidely connect connecting rod 10, connecting rod 10 is connected an end of lever 11, the other end of lever 11 is connected with screw rod 3, be with return spring 2 on the screw rod 3, an end of return spring 2 is connected on the packing ring 1, and the other end is connected on the loam cake 4 of fixed mount 23 upper ends, the edge of rotating disk 5 is row picture series 7 symmetrically, be positioned at housing and also have light-source control system 17, the camera lens part branch in the housing front side comprises main two lucifuge tubes 22 looking tube 21 and be positioned at its both sides, and screw tip has button 13.Whenever by a button 13, screw rod 3 moves upward by lever 11 kinematic links 10, drives sour jujube and grabs 9 around turning over certain angle around point 12, turns over same angle and makes rotating disk turn over equal angular thereby drive ratchet, makes to be presented on that picture transfers next in the visual field.When amblyopia infant band great interest and watched picture like this, accepted that HONGGUANG stimulates and the purpose that reaches treatment.

The more traditional Therapeutic Method of this utility model is interesting strong, and infant is easy to accept, and stimulated fully by HONGGUANG during therefore each treatment, has shortened the course of treatment, and easy to operate, moderate cost both had been suitable for hospital and has used, and was suitable for home-use again.

Fig. 1 is a population structure sketch map of the present utility model, wherein:

2 return springs, 5 rotating disks, 6 platens, 7 pictures, 13 buttons, 14 sounder, 15 light filters, 16 bulbs, 17 light-source control systems, 18 on and off switch, 19 reset switches, 20 display lamps, 21 main tube, the 22 lucifuge tubes looked.

Fig. 2 is a picture rotating mechanism structure chart, wherein:

1 packing ring, 2 return springs, 3 screw rods, 4 loam cakes, 5 rotating disks, 6 platens, 7 pictures, 8 balance pivots, 23 fixed mounts, 24 rotating shafts.

Fig. 3 grabs ratchet structure figure for sour jujube, wherein:

3 screw rods, 8 balance pivots, 9 sour jujubes grab, 10 connecting rods, 11 levers, 12 sour jujubes are grabbed around point, 24 rotating shafts, 25 ratchets.

Fig. 4 is the light-source control system electrical schematic diagram.

The utility model will be further described below in conjunction with accompanying drawing.

Rotary picture chip chromatelopsia theuparatic apparatus as shown in Figure 1 is made up of camera lens part, picture rotating mechanism and the Lights section, and wherein the picture rotating mechanism is in the centre.The camera lens part is looked 21 and two lucifuge tubes 22 of tube by a master and is formed.The left eye right eye all just can be received treatment without blink like this.The main tube 21 of looking is behind a convex lens, and its visual field just in time covers on the picture of rotating disk 5.The structure chart of picture rotating mechanism such as Fig. 2.

When touching the button 13 depress spiro rods 3 with hands, screw rod 3 moves down together with union joint, because lever 11 transmission moves upward connecting rod 10 and sour jujube grabs 9 sliding eye and connecting rod 10 upper ends and is slidingly connected, connecting rod 10 moves upward and promotes sour jujube and grab 9 around turning over certain angle around point, drive ratchet 25 like this and turn over certain angle, rotating disk 5 is fixed in the same rotating shaft 24 with ratchet 25, thereby rotating disk also turns over same angle; When decontroling button, because the effect of return spring 2 makes screw rod 3 return to original state together with lever 11, sour jujube grabs 9 and also oppositely turns over equal angular, returns to original state.Picture 7 is arranged in the edge of rotating disk 5 symmetrically.

Light-source control system of the present utility model can adopt circuit as shown in Figure 4, wherein ic chip ₁And capacitor C ₂, C ₃Form regulated power supply, its on off state is by on and off switch 18 controls, by ic chip ₂And resistance R ₁Form the sound equipment part, by ic chip ₃And resistance R ₂, capacitor C ₄, C ₅Form cycle of operation control section (by reset switch 19 controls), by ic chip ₄And resistance R ₅, R ₆, capacitor C ₇And the bidirectional triode thyristor composition flashes the Lights section.

In use, energized, promptly click reset switch 19, the intravital light source that flashes of shell is started working, and obtains the red-light source of a flicker through optical filter, when treatment time arrives the timing controlled value, automatically cut off the electricity supply, and music is given the correct time, and as pressing reset switch 19 again, then can carry out the treatment of second cyclic process according to the treatment needs.When treatment, whenever by the button of a picture rotating mechanism, picture then turns over lattice to infant with hands, interchangeable again a series of paintings sheet after a circulation treatment process finishes, thus infant can be received treatment in appreciating picture.
