Abstract
The utility model discloses a pair of novel detection glasses which comprises an outer shell, a power supply, a light source, a light focusing system and a variable ocular, wherein the light source is a luminous diode of which the illuminance is more than 20 lumens, and the luminous diode gives off white light. A light focusing mirror, a rotary diaphragm disk, an objective in the light focusing system are in turn arranged along a main light route of the luminous diode light source, and the tail end of the light focusing system is provided with a turning reflecting mirror. The variable ocular is positioned above the light focusing mirror and the objective and is a rotatable diopter disc. A plurality of small glass lens with different diopters are arranged on the diopter disc, and the diopter range is from + 20 D to-35 D. The detection glasses product has the advantages of high inspection and using brightness, low power consumption and stable capability, and the utility model does not generate radiation injury to eyes in the long time using.
Description
Technical field
This utility model relates to a kind of ophthalmology checking Instrument, is applicable to the inspection retinopathy.
Background technology
Ophthalmoscope is a kind ofly to be used to check whether the optical fundus exists the instrument of retinopathys such as hemorrhage, retinal hole.At present, the ophthalmoscope as the conventional indagation instrument of retinopathy all is to use electric filament lamp or halogen tungsten lamp as lighting source.Its manufacturing technology maturation, performance also can satisfy general operational requirement, but can't overcome the defective that its life-span is short, power consumption is big.When making battery operation, the power consumption senior general limits the time that ophthalmoscope once can use continuously and produces more refuse battery thus, and is unfavorable to environmental protection.In addition, also contain ultraviolet and infrared ray composition in the light that these bulbs send, the irradiation of long-time, high brightness will produce radiation injury to eyes.
The utility model content
The technical problems to be solved in the utility model is: a kind of novel ophthalmoscope is provided, and this ophthalmoscope long service life, little power consumption, and use does not have radiation injury to human eye for a long time.
The technical solution of the utility model is: a kind of novel ophthalmoscope, comprise shell, power supply, light source, condenser system and variable eyepiece, and described light source is a light emitting diode; Condenser lens in the described condenser system, rotary diaphragm dish, object lens set gradually along the main optical path of LED source, and its condenser system end is provided with a steering reflection mirror, and described variable eyepiece is positioned at the top of condenser lens and object lens.
The further technical scheme of this utility model is: a kind of novel ophthalmoscope, comprise shell, power supply, light source, condenser system and variable eyepiece, and described light source is the above light emitting diodes of illuminance 20 lumens; Condenser lens in the described condenser system, rotary diaphragm dish, object lens set gradually along the main optical path of LED source, and its condenser system end is provided with a steering reflection mirror, and described variable eyepiece is positioned at the top of condenser lens and object lens.
The more detailed technical scheme of this utility model is: a kind of novel ophthalmoscope, comprise shell, power supply, light source, condenser system and variable eyepiece, and described light source is the above light emitting diodes of illuminance 20 lumens; Condenser lens in the described condenser system, rotary diaphragm dish, object lens set gradually along the main optical path of LED source, its condenser system end is provided with a steering reflection mirror, described variable eyepiece is positioned at the top of condenser lens and object lens, it is a rotatable dioptric scale, it is provided with the dioptric little eyeglass of a plurality of differences, and its diopter scope is+and 20D is to-35D.
The utility model has the advantages that: brightness height, low in energy consumption is used in the inspection of this ophthalmoscope product, stable performance, and long-time use can not produce radiation injury to eyes.When using battery as power supply, the time that the ophthalmoscope one-time continuous is used prolongs greatly.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a light channel structure sketch map of the present utility model;
Fig. 3 is the partial structurtes sketch map of this utility model light source, condenser system.
Wherein: 1 light emitting diode; 2 condenser lenss; 3 rotary diaphragm dishes; 4 object lens; 5 steering reflection mirrors; 6 variable eyepieces; 7 little eyeglasses; 8 tested eye.
The specific embodiment
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, a kind of novel ophthalmoscope comprises shell, power supply, light source, condenser system and variable eyepiece.
Power supply adopts two batteries, and light source is that an illuminance is the above light emitting diodes that emit white light of 20 lumens.Condenser system is made of condenser lens, rotary diaphragm dish, object lens, steering reflection mirror, its condenser lens is arranged at the dead ahead of light emitting diode, the rotary diaphragm dish is positioned at the dead ahead of condenser lens, it is the colyliform vinyl disc, on a plurality of apertures are arranged, mesh flake, crack sheet, light filter etc. are housed, when light during on the aperture respectively by the rotary diaphragm dish, can occur different hot spots respectively, the doctor can select different hot spots with situations such as examining purpose according to the size of patient's pupil, the position of pathological changes.In the place ahead of object lens one steering reflection mirror is set, when light is injected, it is turned to the optical fundus that shines the tested person.Variable eyepiece is positioned at the top of condenser lens and object lens, and it is a rotatable dioptric scale, and promptly a plastics rotating disk is provided with the dioptric little eyeglass of a plurality of differences, and its diopter scope is+and 20D is to-35D.
Claims (3)
