Abstract

The utility model provides a multi-functional examining instrument for the eyes, belonging to a complex examining instrument for the eyes. The multi-functional examining instrument for the eyes comprises a basal disc and a functional disc which are two concentric circular discs. The two circular discs are provided with a sight window, a cornea astigmatic dial, an astigmatic dial, an astigmatic chart, a slit scope, a small aperture mirror, a martorelli rod, and red and green color lenses, etc. By matching with the basal disc or the rotary function disc, the utility model can carry out examination for corneal degree of curvature, corneal astigmatism, ocular paralysis, simulated blindness, color blindness, distinguish color force of color vision, double vision, diaphragm resultant force, binocular vision, and the distinction between physiology iridescent vision and pathologic iridescent vision, and determination for stereo vision in the clinical use. The utility model overcomes the defects of inconvenient use, carrying, and custody, and high cost of a single type examining instrument.

Description

Multi-functional instrument for examining the eyes

This utility model belongs to a kind of apparatus that is used for eye disease diagnosis, inspection, particularly a kind of serving many purposes and the comprehensive detector of function.

The apparatus of generally be used at present the clinical ophthalmology diagnosis, checking, as: the corneal astigmatism dish, the astigmatism dish, astigmatic chart, the crack mirror, stenopaic spectacles, red, green mirror, horse Tuo Shi bar etc. is single-piece.Though these apparatus structures are very simple, owing to production waits the aspects reason, purchase together but difficulty, cost is also high, and clinical use, extremely inconvenience such as carries and take care of.

The purpose of this utility model is, design a kind of with the corneal astigmatism dish, astigmatism dish, table, crack mirror, stenopaic spectacles, red, green mirror, comprehensive multiduty ophthalmic diagnosis, examination apparatus that horse Tuo Shi bar etc. is integrated in one.Low to reach cost, clinical use, carry and purpose such as keeping is convenient.

Solution of the present utility model is to adopt two flaky concentric discs, and one as basal disc, and another is as functional disc.Corneal astigmatism dish and a stenopaic spectacles of left and right two symmetric watch windows being set on the basal disc and constituting by chequered with black and white annulus; Handle is located at the below of basal disc.And functional disc comprises two cards of a, b, also is provided with a stenopaic spectacles connecting two cards, crack mirror, horse Tuo Shi bar and a pair of large and small and the position is identical with the basal disc watch window but the color mirror window of redness and green lens is housed respectively on it; Also have one by a plurality of fan-shaped arc astigmatic charies of forming on a card, this astigmatic chart is that 15 ° fan-shaped constitutes by 12 central angles generally; Below astigmatic chart, also be provided with an astigmatism dish of forming by two groups of parallel lines; On the b card, then have one with the identical corneal astigmatism dish of basal disc.

The b face and the basal disc back side of functional disc are overlapping, and at circle centre position two disk activity are connected into one, and functional disc can be rotated relative to basal disc, and the fastening connection of handle and basal disc.

The utility model has the advantages that the corneal astigmatism dish that will use at present, stenopaic spectacles, crack mirror, astigmatism dish, astigmatic chart, red, green mirror.These functions that apparatus commonly used is had in clinical ophthalmology diagnosis, inspection such as horse Tuo Shi bar and hoodwink plate, only the apparatus of forming by two disc-shaped components just reaches its purpose.Correct this comprehensive ophthalmological instruments that uses, in clinical, can finish corneal flexibility, corneal astigmatism, ophthalmoplegia, malingering blindness, achromatopsia, colour vision color discrimination, diplopia, fusion power, stereopsis vision normally whether, the inspection of difference physiological disease rational faculty iridization etc.; Also can carry out ametropic judgement, the mensuration of stereoscopic vision and carry out amblyopia treatment and make the hoodwink plate and use etc.This apparatus not only has clinical use, carries and takes care of convenient, and economical with materials reduces manufacturing cost and use cost exponentially; But also can be used for education experiment, practice of medical college student etc.

Fig. 1 is this utility model structure and basal disc sketch map; In the figure, red, the green mirror (10,14) of functional disc respectively with basal disc on two watch windows 4, overlap (watch window is a through hole).

Fig. 2 is a basal disc a face structural representation;

Fig. 3 is a basal disc b face structural representation.

Among the figure: 1 is basal disc, 2, the corneal astigmatism dish, 3, functional disc, 4, watch window, 5, handle, 6, stenopaic spectacles, 7, rivet, 8, rotary handle, 9, astigmatic chart, 10, red lens, 11, astigmatism dish, 12, the crack mirror, 13, horse Tuo Shi bar, 14, green lens, 15, the corneal astigmatism dish.

Embodiment

Basal disc 1, functional disc 3 all adopt the thick aluminium sheet of 1mm to make, and diameter is φ 100mm; The long 150mm of handle, top is flat, and wherein with the thick 1.2mm of basal disc back side junction part, the bottom is circular, and cross-sectional diameter is φ 10mm, and material is a lucite.The positive finish paint of basal disc plots chequered with black and white donut, ring hem width 5mm; Two watch windows 4, wide 10mm, each 15mm of the back gauge center of circle, both sides; Stenopaic spectacles 6 diameter phi 2mm.The a face of functional disc is the outside, and on it: the action of astigmatic chart 9 is 45mm, 13 each wide 1.5mm of lines, and the angle between adjacent two lines is 15 °; Crack mirror 12 be located at astigmatic chart 9 under, this crack mirror is long 35mm, the bar v notch v of wide 1.5mm; Horse Tuo Shi bar 13 is long 35mm, the sticking Glass rod that is embedded in the functional disc breach of wide 3mm; With apart about 40 ° in crack mirror; 11 every groups of black line segments by 5 long 15mm, wide 1.2mm of astigmatism dish are formed.Two groups of line segments are arranged vertically mutually in crack mirror 12, and between the red lens 10; Red lens 10 is same with the minute surface size and the observation panel 4 of green lens 14, and the lens of present embodiment adopt lucite to make.Corneal astigmatism dish 15 on the functional disc b face and the corneal astigmatism dish on the basal disc 2 are together.

Present embodiment extends to circle centre position with the upper end of handle 5, and by aluminium rivet 7 itself and basal disc, functional disc is connected into one, cements and add binding agent between the handle and the basal disc back side.

This comprehensive phoroscope coils with the conventional using method except that astigmatic chart, astigmatism in clinical use, and all the other all need pass through rotary handle 8 rotating function dishes 3, are used with basal disc 1.That is: any place annulus section on the corneal astigmatism dish 15 on the functional disc is threaded to two watch windows 4 of basal disc, just form a complete corneal astigmatism dish of forming by chequered with black and white annulus (promptly filling black and white ring section), just can be used for carrying out the inspection of astigmatism etc. at the window place; Red, green mirror is threaded to watch window 4, just can carry out the diplopia inspection to the patient, with any bar ophthalmoplegia of judging the paralytic strabismus patient, benumb character and carry out cataract operation before visual function evaluation, look into malingering blindness, cooperate stereogram to check stereopsis function etc.; With horse Tuo Shi bar 13, be threaded to watch window 4, just can carry out the heterophoria inspection; Crack mirror 12 is threaded to observation panel, just can carries out the distinctiveness inspection of physiology, pathologic iridization the patient; Stenopaic spectacles on the functional disc is overlapped with stenopaic spectacles on the basal disc, then can carry out whether emmetropia inspection etc.; And red lens is threaded to observation panel and places patient's amblyopia (to cover in strong eye) at the moment, write, draw, reading etc., then can carry out amblyopia treatment.
