Description
Technical field
The present invention relates to ophthalmic medical checkout facility technical field, be specially a kind of hand-held digital wide-angle ophthalmoscope.
Background technology
It is very difficult that the 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 used is significant for medical diagnosis.The 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 the direct ophthalmoscopy optical fundus, need direct ophthalmoscope to be placed on those who are investigated's the place of close pupil at the moment, the examiner must just can observe the eyes of controlling oneself and need the position checked by offset lens near the ophthalmoscope peephole simultaneously.Thereby this inspection method of being observed by peephole requires face section 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; Simultaneously, owing to observing in order to be convenient near ophthalmoscope, the 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.The optical fundus visual range is little.Use traditional direct ophthalmoscope, user just can be observed and need the position checked by offset lens near the ophthalmoscope peephole.At first in observing principle, usually can only observe the optical fundus in a 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 the slit lamp fundus camera, time and check cost can be increased, eye fundus image can't be recorded.In situation about observing by traditional direct ophthalmoscope can't be recorded with the form of image in time, can't adapt to the growth requirement of modern medical service electronic health record, specifically, both be unfavorable for setting forth check result to patient, also can't the consultation of doctors be discussed with other doctors.The developing history of observation disease that in addition, also can't be visual and clear.
Summary of the invention
For the problems referred to above, the present invention aims to provide a kind of hand-held digital wide-angle ophthalmoscope of simple structure.
For realizing this technical purpose, the solution of the present invention is: a kind of hand-held digital wide-angle ophthalmoscope comprises the wide-angle ophthalmoscope body, the wide-angle lens main body, digital camera system and battery handle, described wide-angle ophthalmoscope body is arranged on the battery handle upside, and described wide-angle lens main body comprises bulb, condenser lens, diaphragm, optical filter, the illumination illuminator, the brightness regulation knob, the diaphragm adjusting knob, the focusing dish, objective lens, focusing lens, reflecting mirror and eyepiece, described bulb is positioned at the diaphragm downside, and a side of diaphragm is provided with condenser lens, reflecting mirror and focusing lens, described optical filter, the illumination illuminator, the brightness regulation knob, the diaphragm adjusting knob, the focusing dish, objective lens and eyepiece all are arranged on the 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 all is provided with the 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, be provided with rechargeable battery in described battery handle, battery is connected with bulb and digital camera system with the contact motor by wire.
As preferably, described digital camera system is for taking the optical fundus disease, and can be presented on 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 the 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.
The present invention compares with the direct ophthalmoscope checked by peep-hole, do not need the close contact of examiner and those who are investigated's face section, also without the 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 the photologging storage, make examination of ocular fundus and fundus photography be completed simultaneously, with the angular field of view scope of direct ophthalmoscope, compare, field range of the present invention is large more than 5 times.
