Abstract
The utility model relates to a convergence exerciser of a near-point determination instrument, which belongs to the medical appliance and is mainly used for a conventional near-point of convergence determination and exercise device. The utility model comprises a lifting support and a platform 2 supported by the lifting support, and two parallel orbits are arranged on the surface of the platform. A movable visual mark device is arranged on the orbits, a visual mark lamp is arranged on the visual mark device, and one end of the platform is provided with a head support. The two orbits are respectively provided with a parallel graduated scale, and the utility model can accurately determine out the distance of the near-point of convergence for a patient with ocular muscle fatigue. Then, the visual mark device is slowly moved from the near point of the convergence to the nose root part of the patient, and returns to the original point after the convergence is broken. Thus, through the repeated exercises, the goal of the elimination of ocular muscle fatigue is achieved. Through an experiment, the total effective rate reaches 97 percent.
Description
This utility model belongs to medical apparatus and instruments, is mainly used in the device that conventional convergence near points is measured and trained.
At present, the method of the most frequently used mensuration convergence near points places patient eyeball horizontal plane 30 centimetre distant places with forefinger or small electric bulb as sighting target for the examiner, make the patient watch sighting target attentively, the examiner shifts near patient's nasion portion slowly with test-object then, note the patient simultaneously two, if a cornea reflection displacement suddenly, this distance is its convergence near points.This method is fairly simple, and shortcoming is that the result is directly perceived inadequately, accurate.The most frequently used method of converge like the spokes of a wheel at the hub training is the nib training, promptly at first be placed on a median line and a bit watch this target apart from the about arm of eye simultaneously attentively apart from two of distant places, in the side slightly on the lower side then slowly by far shifting near with a pencil or other target, return the original place when regarding slur as again, so repetition training.The method is simple, and shortcoming is patient's difficult concentrating, and the training effect is poor.
The purpose of this utility model is that anomalistic distance is measured and converge like the spokes of a wheel at the hub one that is trained for, and adopts scientific and normal training method, makes it convenient, accurate, easy-to-use, and " outer tiltedly latent " that effectively solve people reaches " converge like the spokes of a wheel at the hub deficiency " property asthenopia.
Above-mentioned purpose is achieved in that this device comprises the platform of lifting support and support thereof, and flat surface has two parallel orbits, is equipped with movably sighting target device on the track, and an end of platform is equipped with head rest.Respectively there is the distance of a parallel rule to show that the sighting target device moves the track both sides.The sighting target device is to comprise four moving runners of base and bottom, and upright on the base have a hollow vertical rod, and rod end is with sighting target, is equipped with the sighting target lamp on the sighting target, and its line is by the dc source UNICOM in vertical rod inner chamber and the base cavity.Head rest is to comprise that two are fixed on the support bar of platform edges and are enclosed within compositions such as two localized volume holders of the liftable between support bar and jaw holder.After the patient that need treat was placed on head rest to head like this, the moving target device can be measured the distance of convergence near points and carry out converge like the spokes of a wheel at the hub training.
This device can accurately determine the distance of convergence near points to eye muscle fatigue patient, then from convergence near points, holding vertical rod slowly shifts near patient's nasion portion with the sighting target device return the original place again after converge like the spokes of a wheel at the hub destruction, so repetition training, can enliven and recover the physiological regulation function of extraocular muscles, ciliary muscle and lenticular, strengthen convergence power, promote ocular blood circulation and basal metabolism, reach day of eliminating the eye muscle fatigue.Warp is trained use to 189 routine patients, transference cure person 155 examples, and obvious improver's 28 examples, total effective rate reaches 97%.
Accompanying drawing is a structural representation.
Embodiment: platform 2 in metal triangular support 1 upper support, 2 on platform is gone up the middle part two parallel tracks 3, and respectively there is root rule 4 track 3 both sides, are equipped with the sighting target device on the track 3.The sighting target device comprises base 5-1, four moving runner 5-2 that can roll on track 3 are arranged below it, be equipped with hollow vertical rod 5-3 above the base 5-1, vertical rod 5-3 top is with sighting target 5-4, it can slide up and down and locate with pilot pin 5-5, and sighting target 5-4 is equipped with one side a sighting target lamp 5-6, and it adopts eye-catching red miniature bulb, its line is connected (not shown) by the battery in vertical rod 5-3 inner chamber and the base 5-3, and the centre is equipped with switch 5-7.Want to be equipped with on sighting target lamp 5-6 one side platform 2 edges to close and hold in the palm, head rest comprises two support bar 6-1 that are fixed on platform 2 edges, be with volume holder 6-2 and jaw holder 6-3 on two support bar 6-1, they can slide up and down and locate with the lifting knob 6-4 that is enclosed within on the support bar 6-1 at the 6-1 of support bar.This installs also available alternating current power supply, and rectification is to insert behind the required DC voltage.When using this measurement device convergence near points, patient's head is placed on 6 ones of head rests, adjust lifting support 1, lifting knob 6-4 and pilot pin 5-5's, make forehead withstand volume holder 6-2, lower jaw is put on the jaw holder 6-3, head is fixed well, and makes the patient watch sighting target lamp 5-6 attentively, holds vertical rod 5-3 then, sighting target device 5 is furthered two gradually, watch the position attentively when a glance breaks away from, this distance is convergence near points, when training, be by far and closely progressively shifting near patient's nasion portion with sighting target device 5, when finding that sighting target lamp 5-6 is two, then prove converge like the spokes of a wheel at the hub destroyed, return the original place again, so repetition training can be cured after a period of time.
