Animal eye ophthalmofundoscopeTechnical field
The invention belongs to field of medical device, be specifically related to a kind of animal eye ophthalmofundoscope.
Background technology
Now with on medical, medicinal, when developing a kind of new drug or check that a kind of virus (antibacterial) has anything to injure to human body, employment can not do experiment, common way is tested with animal, such as Mus, rabbit, monkey etc.By checking at the bottom of animal eye, the pathological reaction of this animal to development medicine or virus (antibacterial) can be obtained, thus obtain development medicine or virus (antibacterial) to the approximate symptom of human body.And the eyes size of the eyes of people and animal, pupil size, crystal radius of curvature, optical fundus structure are all different, therefore can not check with the ophthalmofundoscope at the bottom of scrutineer's eye at the bottom of the eye of animal, us are needed to transform with ophthalmofundoscope existing people, make it can be applicable to the eyes of animal, the fundus photograph of the animal eyes clearly of breaking forth.
Summary of the invention
For solving the problem, the invention provides a kind of structure simple, can to Mus, rabbit, the animals such as monkey carry out the animal eye ophthalmofundoscope that optical fundus is detected as picture.
Animal eye ophthalmofundoscope, comprise hardware ophthalmofundoscope, described hardware ophthalmofundoscope comprises objective lens unit, and described objective lens unit comprises again one group of fixture mirror assembly and one group of replaceable objective lens unit, and described replaceable objective lens unit comprises the first object lens, the first objective tube, described fixture mirror assembly comprise
Second object lens and the second objective tube, described replaceable objective lens unit and fixture mirror assembly headtotail, the tail end of described replaceable objective lens unit is provided with the first trim ring, and the head end of described fixture mirror assembly is provided with the second trim ring.
Further, between described fixture mirror assembly and replaceable objective lens unit for being threaded.
The present invention compared with prior art, it has following beneficial effect: objective lens unit of the present invention is made up of one group of fixture mirror assembly and one group of replaceable objective lens unit, can for the size of other animal eyes and the structure different same situation from human eye, according to the eyes feature (size of eyes of different animals, the size of pupil, Qu Guangdu is different, and axiallength is different, carry out optical compensation adjustment, make the optical fundus of different animals can become image clearly.

Detailed description of the invention
The present invention is further described below in conjunction with specific embodiment and accompanying drawing:
Consult a kind of animal eye ophthalmofundoscope shown in Fig. 1 and Fig. 2, comprise hardware ophthalmofundoscope, described hardware ophthalmofundoscope comprises objective lens unit, described objective lens unit comprises again one group of fixture mirror assembly 1 and one group of replaceable objective lens unit 2, described replaceable objective lens unit 2 comprises the first object lens 3, first objective tube 4, described fixture mirror assembly 1 comprises the second object lens 5 and the second objective tube 6, described replaceable objective lens unit 2 and fixture mirror assembly 1 headtotail, the tail end of described replaceable objective lens unit 2 is provided with the first trim ring 7, the head end of described fixture mirror assembly 1 is provided with the second trim ring 8.
For being threaded between described fixture mirror assembly 1 and replaceable object lens 2 assembly.
The present invention compared with prior art, it has following beneficial effect: objective lens unit of the present invention is made up of one group of fixture mirror assembly and one group of replaceable objective lens unit, can for the size of other animal eyes and the structure different same situation from human eye, according to the eyes feature (size of eyes of different animals, the size of pupil, Qu Guangdu is different, and axiallength is different, carry out optical compensation adjustment, make the optical fundus of different animals can become image clearly.
Embodiment recited above is only be described the preferred embodiment of the present invention, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
