Description
Art
This utility model belongs to field of medical technology, particularly a kind of photograph accessory for taking medical photo.
Background technology
Fundus photography is Application comparison a kind of diagnostic mode widely in ophthalmology, and adopt the mode of fundus photography, doctor can check the optic nerve on patient optical fundus intuitively, and whether retina etc. have pathological changes to occur.
Tradition ophthalmofundoscope belongs to armarium, and general uses by during diagnosis, be made up of, complicated structure illuminator and viewing system, and volume is comparatively large and cost is higher, is not easy to carry with.Tradition ophthalmofundoscope generally can only be observed, and does not have image and stores and analyzing and processing function, cause diagnosis subjectivity larger.
The patent No. is that the utility model of CN1080509A discloses a kind of hand-held ophthalmoscope, but it adopts the mode of highlighted exposed photographic to fundus photography, and higher source luminance can stimulate pupil to reduce instantaneously, reduces the quality of taking pictures.Although be furnished with photographic system, external photographing unit not only makes complex structure, loses portability, too increases cost.
The patent No. is that the utility model of CN103099600A discloses a kind of examination of ocular fundus instrument, but its Lights section complex structure, and inside is configured with mirror of giving out light, need focusing lens that light source just can be made to meet the demands, operate relatively loaded down with trivial details, lose agility, and light-source brightness is unadjustable, is difficult to the requirement meeting examiner.
The patent No. is that the utility model of CN103815869A discloses a kind of hand-held fundus camera, but it adopts near-infrared and white light two kinds of LED as lighting source, and need prepare imaging modules and display module voluntarily.
Utility model content
The purpose of this utility model is the above-mentioned deficiency overcoming prior art, provides a kind of and can make full use of the photograph accessory that device ready-made on mobile phone carries out medical photograph taking.The mobile phone shell of medical photo photograph accessory to smart mobile phone that this utility model provides is improved, increase convergence of rays camera lens and imaging enlarging lens, after improved mobile phone shell is installed at the smart mobile phone back side, the flash lamp of mobile phone can be adopted as light source, utilize the position such as optical fundus, internal ear, tooth, skin of mobile phone camera to those who are investigated to take pictures, after picture preserved by mobile phone, examiner can be further analyzed process to medical images such as optical fundus.The technical solution of the utility model is as follows:
For taking a mobile phone camera accessory for medical photo, comprising the mobile phone shell matched with the smart mobile phone carrying out medical photograph taking, described mobile phone shell offering flash lamp aperture and shooting head bore; It is characterized in that, and convergence of rays camera lens and imaging enlarging lens are set in mobile phone shell, convergence of rays camera lens comprises two groups of optics convex lens, the lens barrel of first group of convex lens is fixed on the flash lamp aperture periphery of mobile phone shell, the lens barrel of second group of convex lens is flexibly connected with first group, distance between two groups of convex lenss can regulate, and two groups of convex lenss and flash lamp are positioned on same optical axis, is used for carrying out twice convergence to the diverging light of flash lamp and makes it be irradiated to the position needing inspection; Imaging enlarging lens is just also connected with mobile phone shell to shooting head bore, enters imaging enlarging lens, then enter mobile phone camera from the light needing the position checked to reflect, and makes mobile phone obtain the image needing check point.
Can be threaded connection between the lens barrel of the lens barrel of first group of convex lens and second group of convex lens.
This utility model is mainly innovated the technology of existing ophthalmofundoscope and so on, innovation mainly contains 2 points, the first can carry out regulating the observation requirement meeting examiner as the brightness of the flash lamp of light source, it two is that distance between two groups of convergence of rays camera lenses can regulate, convergence of rays is made to arrive the position needing inspection, such as converge between eyeball to optical fundus when carrying out optical fundus and taking pictures, thus optionally can observe region, whole optical fundus or concentrate a certain discreet region of observation.This Mobile phone housing structure for taking medical photo is simple, can carry with, easy to use.Owing to relying on the extremely wide mobile phone of universality, described fundus photography accessory can with mobile phone plug and play.Beneficial effect is as follows:
(1) Mobile phone housing structure for taking medical photo described in the utility model is simple, easy to carry, user can check positions such as optical fundus at any time voluntarily quickly and accurately, the device volume being compared to traditional ophthalmofundoscope and so on is comparatively large, and not portative problem is effectively solved.
(2) utilize mobile phone flashlight as light source, battery of mobile phone abundance can ensure that light intensity meets photographing request, and light-source brightness scalable, the inspection apparatus being compared to traditional ophthalmofundoscope and so on needs autogamy power-supply system, and the fixing problem of the few and light-source brightness of electricity improves.
Distance between (3) two groups of convergence of rays camera lenses is adjustable, optionally can observe the whole position needing to check, the a certain discreet region in such as optical fundus or optical fundus, the problem being compared to existing ophthalmofundoscope observation place fixing is resolved, and is more conducive to examiner and diagnoses.
(4) utilize mobile phone camera as taking lens, resolution is high, and image stabilization is clear and can preserve images such as eye fundus images, and the device being compared to traditional ophthalmofundoscope and so on can only be observed, and the problem can not preserving image is resolved.
Accompanying drawing explanation
Fig. 1 is the structure key diagram of the mobile phone camera accessory for taking medical photo described in the utility model.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, this utility model embodiment is described in further detail:
For fundus photography, the present embodiment is described, refers to Fig. 1.Fundus photography accessory comprises: 1, mobile phone shell; 2, convergence of rays camera lens first group of convex lens; 3, convergence of rays camera lens second group of convex lens; 4, imaging enlarging lens.Wherein convergence of rays camera lens 2 and imaging enlarging lens 4 and mobile phone shell interfix, and convergence of rays camera lens first group of convex lens 2 and second group of convex lens 3 are threaded connection.
During use, mobile phone shell 1 is enclosed within mobile phone, second group of convergence of rays camera lens 3 is threadedly attached on first group of collecting lens 2, open mobile phone flashlight and cell phone cameras software, convergence of rays camera lens 3 is aimed at the eyeball of those who are investigated, the diverging light that now mobile phone flashlight sends enters first group of convex lens 2 and forms directional light and enter second group of convex lens 3, light assembles the eyeball entering those who are investigated again, illuminate optical fundus, the light that fundus reflex returns enters imaging enlarging lens 4, enter mobile phone camera again, regulate the brightness of mobile phone flashlight, until mobile phone screen can observe eye fundus image clearly, now rotation collective lens 3 regulates the distance between collective lens 2 and camera lens 3, optionally can observe region, whole optical fundus or concentrate and observe a certain discreet region.Imaging clearly can be taken pictures after stablizing and be preserved eye fundus image to carry out the follow-up treatment and analysis to eye fundus image.
Although this utility model improves for ophthalmofundoscope.But be not only taking pictures for optical fundus picture, the inspection at other positions can also be applied to and take pictures.
