Description
Technical field
This utility model relates to a kind of hand-held fundus camera.
Background technology
In order to ensure that fundus camera photographs high-quality human eye retina image smoothly, need to make human eye's visual axis and optical axis included angle remain in certain angle, therefore, fundus camera, except main optical path part, also will add the sighting target allowing human eye fixedly watch attentively.One method directly adds sighting target in the optical path, and the eye watching sighting target attentively is exactly tested eye.There is two problems in this method: a lot of patient is simple eye ill, and existence fixedly watches problem attentively, but other eyes are healthy, in this case, just cannot observe the disease eye of patient.In addition, from fundus camera is manufactured, introduce other visible ray in the optical path and add veiling glare intensity and easily form ghost image, the resetting difficulty of optical system is also significantly promoted, is unfavorable for assembling production on a large scale.
Utility model content

Two-dimensional image sensor, controller, display module and memorizer are all installed in shell; The lower end of shell is located at by handle, and button is installed on handle, and battery is installed in handle; One end of barrel-type casing is communicated with a sidewall of shell, and the first lens subassembly, the second lens subassembly and lighting source sequentially interval are installed in barrel-type casing, and lighting source is between the second lens subassembly and two-dimensional image sensor; Two visible light sources are all installed on this sidewall of this shell, and lay respectively at left and the right of barrel-type casing, and the light direction of visible light source is consistent with the light direction of lighting source; Two-dimensional image sensor, display module, memorizer, button, visible light source and lighting source are all electrically connected controller, and battery is used for power supply to visible light source, lighting source and controller.
Preferably, this lighting source comprises the infrared LED being used as to guide light source and the white light LEDs being used as exposure light source.
Preferably, the wave band of infrared LED is 850nm.
Preferably, the wave band of white light LEDs is 450nm-650nm.
Preferably, barrel-type casing one end is provided with the first connecting portion, and this sidewall of shell is provided with the second connecting portion, and the first connecting portion removably connects the second connecting portion.
The beneficial effects of the utility model are at least as follows:
This utility model can realize the another eye fixation of patient, can take the left eye of patient and the optical fundus of right eye respectively, improve observation accuracy, and this camera architecture is simple, easy to operate, is applicable to batch production.
Accompanying drawing explanation
Fig. 1 is the axonometric chart of the better embodiment of this utility model hand-held fundus camera.
Fig. 2 is the generalized section of the camera main-body of the hand-held fundus camera of Fig. 1.
Fig. 3 is the generalized section of the lens barrel of the hand-held fundus camera of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
Refer to Fig. 1 to Fig. 3, this utility model relates to a kind of hand-held fundus camera, and its better embodiment comprises camera main-body 2, lens barrel 1 and two visible light sources 3.Camera main-body 2 comprises shell 29, handle 27, two-dimensional image sensor 21, controller 22, button 23, battery 24, display module 25 and memorizer 26.Lens barrel 1 comprises barrel-type casing 14, first lens subassembly 12, second lens subassembly 13 and lighting source 11.
Two-dimensional image sensor 21, controller 22, display module 25 and memorizer 26 are all installed in shell 29.The lower end of shell 29 is located at by handle 27, and button 23 is installed on handle 27, with handled easily; Battery 24 is installed in handle 27, to save space.One end of barrel-type casing 14 is communicated with a sidewall of shell 29, and the first lens subassembly 12, second lens subassembly 13 and lighting source 11 sequentially interval are installed in barrel-type casing 14, and lighting source 11 is between the second lens subassembly 13 and two-dimensional image sensor 21.Two visible light sources 3 are all installed on this sidewall of this shell 29, and lay respectively at left and the right of barrel-type casing 14, and the light direction of visible light source 3 is consistent with the light direction of lighting source 11.Two-dimensional image sensor 21, display module 25, memorizer 26, button 23, visible light source 3 and lighting source 11 are all electrically connected controller 22, and battery 24 is for powering to visible light source 3, lighting source 11 and controller 22.
