Description
Technical field
This utility model relates to ophthalmic medical checkout facility technical field, is specially a kind of hand-held digital wide-angle ophthalmoscope.
Background technology
It is very difficult that doctor needs the trickle pathological changes on direct viewing patient optical fundus, but the many pathological changes of human body can present on optical fundus, unique can observing directly in optical fundus in human vas, by the diagnosis on optical fundus, can observe the diseases such as hypertension, sclerosis of blood vessels, diabetes, retinal hemorrhage.So the ophthalmoscope be convenient for carrying a, function being used is significant for medical diagnosis.Tradition direct ophthalmoscope is a kind of for checking the ophthalmological instrument on crystalline lens, retina and optical fundus.At present, traditional direct ophthalmoscope mainly contains following shortcoming: pay respect patients' feeling and examiner are easily not tired.While using direct ophthalmoscopy optical fundus, need direct ophthalmoscope to be placed on those who are investigated's the place of close pupil at the moment, examiner must just can observe the eyes of oneself position that needs inspection by offset lens near ophthalmoscope peephole simultaneously.Thereby this inspection method of observing by peephole requires face portion and the adjacent direct ophthalmoscope of eyes of user to make examiner and those who are investigated's face very close, cause inconvenient and uncomfortable; Meanwhile, owing to observing in order to be convenient near ophthalmoscope, examiner need to take a kind of passive posture of catering to those who are investigated's head position (as bow, bend over), easily tired.Optical fundus visual range is little.Use traditional direct ophthalmoscope, user just can be observed the position that needs inspection by offset lens near ophthalmoscope peephole.First in observing principle, conventionally can only observe an optical fundus in very little field range, the angular field of view scope of general traditional direct ophthalmoscope is about 3 °-4 °.In order to observe the situation on whole optical fundus, need to repeatedly adjust position and the angle of direct ophthalmoscope, user also needs to adjust accordingly posture, having increased the review time has also increased those who are investigated's fatigue and uncomfortable, if adopt slit lamp fundus camera, time and check cost can be increased, eye fundus image cannot be recorded.In situation about observing by traditional direct ophthalmoscope cannot be recorded with the form of image in time, cannot adapt to the growth requirement of modern medical service electronic health record, specifically, both be unfavorable for setting forth check result to patient, also cannot the consultation of doctors be discussed with other doctors.The developing history of observation disease that in addition, also cannot be visual and clear.
Utility model content
For the problems referred to above, this utility model aims to provide a kind of hand-held digital wide-angle ophthalmoscope of simple structure.
For realizing this technical purpose, scheme of the present utility model is: a kind of hand-held digital wide-angle ophthalmoscope, comprises wide-angle ophthalmoscope body, wide-angle lens main body, digital camera system and battery handle, described wide-angle ophthalmoscope body is arranged on battery handle upside, and described wide-angle lens main body comprises bulb, condenser lens, diaphragm, optical filter, illumination illuminator, brightness regulation knob, diaphragm adjusting knob, focusing dish, objective lens, focusing lens, reflecting mirror and eyepiece, described bulb is positioned at diaphragm downside, and a side of diaphragm is provided with condenser lens, reflecting mirror and focusing lens, described optical filter, illumination illuminator, brightness regulation knob, diaphragm adjusting knob, focusing dish, objective lens and eyepiece are all arranged on wide-angle lens body interior, and described digital camera system comprises CMOS or CCD, digital information processing system, storage system, LCDs, CMOS or CCD are arranged on a side of condenser lens, and LCDs is arranged on the upside of battery handle, and a side of LCDs and battery handle is all provided with control button.
As preferably, described wide-angle ophthalmoscope body is provided with three kinds of runners, is used for respectively controlling bulb brightness, diaphragm type and focusing lens.
As preferably, in described battery handle, be provided with rechargeable battery, battery is connected with bulb and digital camera system with contact motor by wire.
As preferably, described digital camera system is used for taking optical fundus disease, and can be presented in LCDs in real time.
As preferably, described hand-held digital wide-angle ophthalmoscope photographs picture by digital camera system and can be stored on storage card, and directly by usb, connect computer and read, and hand-held digital wide-angle ophthalmoscope is by light path converting, and the angle of visual field is common directly Oph more than 5 times.
As preferably, described hand-held digital wide-angle ophthalmoscope has adopted coaxial illumination path.
This utility model is compared with the direct ophthalmoscope checking by peep-hole, do not need the close contact of examiner and those who are investigated's face portion, also without examiner, when checking, adopt the positive position that caters to those who are investigated, can at any time the position recording of observing be become in addition to photologging storage, examination of ocular fundus and fundus photography are completed simultaneously, compare with the angular field of view scope of direct ophthalmoscope, this utility model field range is large more than 5 times.
