Abstract

The utility model relates to a multipurpose charging ophthalmoscope, composed of a lens head and a lens body. A reading chart is drawn on the surface of the lens body, and two cassettes are arranged in the lens body. One cassette is used for storing a color vision chart, and the other is used for storing a battery. A designed telescopic plug is connected with an outer power supply, the outer power supply is connected with a depressing and rectifying charging plate which is arranged in the lens body, and the battery can be charged. Two switches are arranged at one side of the lens body and are respectively used for controlling the light bulb of the ophthalmoscope and a flashlight bulb. The utility model can be used for examining eyeground, external eyes, short sight and color vision and provides convenient to treat eye diseases for ophthalmology medical personnel. Compared with an existing ophthalmoscope, the utility model has the advantages of reasonable design, convenient operation, complete function, easy fabrication, low cost, etc.

Description

Multipurpose charging ophthalmoscope

This utility model belongs to a kind of medical supplies.

At present existing AC and DC ophthalmoscope.Alternating current powered ophthalmoscope links to each other with ophthalmoscope with a lead after with transformator 220 volts of alternating currents being reduced to safe voltage, and this ophthalmoscope can not be carried, and uses the restriction that is subjected to conductor length and feels inconvenient.Correspondingly be battery powered ophthalmoscope, use No. one or No. three aneroid battery, volume is bigger, and needs often to change battery, does not note slightly, battery drain causes the ophthalmoscope corrosion.More than two types ophthalmoscope also have two shortcomings, the first is used common little shape bulb, luminance difference is easily burnt, it two is that performance is single, can not make the usefulness of other inspections.

The purpose of this utility model is to overcome the deficiency of above ophthalmoscope, makes it have multiple function, can examine eye, can have an eyesight test, and can look into achromatopsia, can also make Pocket torch and use.

The technical solution of the utility model is: Oph power supply has been done change, adopt chargeable No. five high-energy batteries of two joints, and be equipped with interior transformation, the panel that rectification and charging are integrated, having designed a kind of telescopic two phase plugs links to each other on electric with this plate, two-phase formula plug is hidden in the ophthalmoscope body at ordinary times, from the ophthalmoscope body, stretch out during charging and connect 220 alternating current power supplys, selected little shape high light bulb of two long-life high brightness for use, one is used for ophthalmoscope, one is used for torch, in the ophthalmoscope body, be provided with a box-shaped space, at ordinary times color vision plate is placed in one, take case lid is opened and can be taken out, be painted with near vision test type in a side of ophthalmoscope body.

Be described in detail it below in conjunction with accompanying drawing:

Fig. 1 is that the master looks sketch map, and 1 is the ophthalmoscope head, and 2 is the ophthalmoscope body, and 3 is standard near vision chart.

Fig. 2 is the rearview of ophthalmoscope body, 10 condenser carriers for fixing ophthalmoscope bulb and optically focused, and 11,12 is two to save chargeable high-energy batteries, 16 is the holder of ophthalmoscope head.

Fig. 3 is the left view of Fig. 2, and 9 as described in Figure 2, and 13 is the battery case cover plate.

Fig. 4 is the right view of Fig. 2, and 5,6 as described in Figure 2.

Fig. 5 is the upward view of Fig. 2, and 6,7 as described in Figure 2, and 14 is the color vision graph cover plate.

Fig. 6 is spot light lamp bulb assembling sketch map, and 10 is condenser carrier, and 15 is the fixed mount of spot light lamp bulb D, and 16 is the ophthalmoscope holder.

Fig. 7 then is electrical control figure of the present utility model, I step-down rectifier plate, and II is the high-power rechargeable battery, K ₁Be torch beginning, K ₂Be the ophthalmoscope switch.

As shown in Figure 1: this utility model is the rechargeable ophthalmoscope of a kind of multipurpose, form by camera lens and shank, be painted with near vision test type on the surface of shank, two magazines are arranged in it, one is used for adorning color vision graph, another is used for packed battery, design has an extension type external power supply plug, and external power is introduced step-down rectifier charging panel in the built-in shank, can charge the battery, shank one side has two switches, be used for controlling ophthalmoscope bulb and pocket lamp bulb respectively, ophthalmoscope head 1 adopts general ophthalmoscope head, as the Oph camera lens of GFJY-01 type of Tianjin product, directly one slotting on the ophthalmoscope head holder 16, the nut that is tightened gets final product.The installation of ophthalmic electric bulb connects together bulb D and holder 16 through fixed mount 15 as shown in Figure 6, and optically focused lamp bracket 10 is stuck on the bulb D, and on condenser carrier 10 right-hand a circular arc being arranged promptly is condenser lens, and light was in the through ophthalmoscope head of condenser lens when lamp D was bright.

Can find out in conjunction with Fig. 2 to figure five: two cover plates are arranged in shank 2; Cover plate 13 is pulled out; Replaceable battery; Cover plate 14 is pulled out the desirable color vision plate (such as the color vision plate of Wang Fang state compilation) that goes out; With the telescopic plug pushing hands 8 of finger push-and-pull; Can make slotting contracting formula attaching plug 9 extended or retracted; With hand difference pull switch ophthalmoscope bulb switch 5 or flashlight switch 6; Then can control respectively the bright of ophthalmoscope bulb D or pocket lamp bulb 7 or go out; D is bright to carry out funduscopy; The 7 bright examination of external eye that carry out

Among Fig. 13 is standard near vision chart, because eyesight testing symbol wherein is too little, omits among this figure.

Step-down rectifier charging panel II in Fig. 7 has been used the rectification charging plate in the existing miniature Chargeable electric torch, in order that make full use of prior art.

Can see that from above-mentioned this utility model can carry out examination of ocular fundus, examination of external eye, examination of near vision, examination of color sense, this provides great convenience to the diagnosis and treatment of ophthalmic for undoubtedly the ophthalmology medical worker.This utility model is compared with former ophthalmoscope, then demonstrates advantages such as reasonable in design, easy to use, multiple functional, easy to manufacture, with low cost.Should note in only being to use charging in appropriate, to keep cell voltage normal, the time spent should not take out battery for a long time, in case leakage damages other components and parts in the shank.

Claims

1, the rechargeable ophthalmoscope of a kind of multipurpose, form by camera lens and shank, it is characterized in that: be painted with near vision test type on the surface of shank, two magazines are arranged in it, one is used for adorning color vision graph, and another is used for packed battery, and design has the extension type external power supply plug, shank one side has two switches, is used for controlling ophthalmoscope bulb and pocket lamp bulb respectively.
