Description
Technical field
The present invention relates to examination equipment for eye field, in particular to a kind of novel RAPD detector.
Background technique
Pupillary light reflex is that light stimulation causes a kind of miotic autonomic nerve stress reaction, anti-to light by pupil
It penetrates nerve pathway and completes this process.Pupillary light reflex access refers to since retina, through optic nerve, optic chiasma and view
Beam, then pretectal area is reached through upper arm mound, the aixs cylinder of accessory nucleus of oculomotor nerve replaces neuron through oculomotor nerve to ciliary ganglion,
Postganglionic fibers dominates sphincter pupillae, causes the miotic whole process of bilateral.Any one in above-mentioned smooth reflex path damages
It is bad to can lead to light hyporeflexia or disappearance.
Neuroretinal rim area (RAPD) is the important diagnostic foundation of optic nerve disease, currently, both at home and abroad clinically
It is all made of directly inspection method manually to be detected, doctor uses flashlight direct irradiation patient's eyes, observes by the naked eye trouble
Person's pupil of both eyes is other to light reflection difference, although such test mode is very intuitive, both non-quantitative or not objective, for eyes
The nuance of reaction of pupil to light can not also be differentiated completely, and the early stage sign of many optic nerve diseases may be only comprising slight
Neuroretinal rim area, in view of the irrecoverability of the vision impairment of optic nerve disease, if can be counted to RAPD
The quantitative description of word will be of great significance to the early diagnosis of optic nerve disease.Currently, U.S. KONAL MEDICAL
The RAPDx of company is mainly used for being passed to relativity pupil the screening and diagnosis of deficiency disorders, but its tracking accuracy is lower, and pierces
Laser source is relatively simple to be only red light；The binocular instrument for examining pupil of this project early period is one camera binocular imaging, due at
Image distance from and visual field factor, binocular imaging have aberration problems, cause binocular pupil image not reciprocity, measuring result error is larger.
The ophthalmology RAPD quantitative measurment plate of patent 201620159942.9 is quantified by installing neutral different densities filter
There is measurement inconvenience in measurement, actual operator, and sometimes measurement result is difficult to the disadvantages of defining.
Existing inspection device and method at least have the disadvantage in that
1, existing alternately exposure experiments to light can only be judged whether there is roughly using flashlight stimulation and naked-eye observation
RAPD, estimation reaction of pupil to light variation can not carry out objective, quantitative, accurately measurement, slight abnormality can not be differentiated；
2, RAPD quantitative measurment plate, manual operation, measurement is inconvenient and measurement result is inaccurate；3, RAPDx stimulating light source is single is only

End is connected with pulling plate 17；Second spring 18 is connected between pulling plate 17 and the upper surface of nut seat 90.
Wherein, wedge block 94 on its inclined-plane is provided with wave heave 940, the inner upper wall of wedge groove 100 offers
The contoured shaped recess cooperated with wave heave 940；When wedge block 94 passes in and out in wedge groove 100, pass through wave heave 940 and waveform
Groove cooperation contact, can increase the frictional force between the inclined-plane of wedge block 94 and the inner upper wall of wedge groove 100, make wedge block 94
Stable and firm it can support wedge groove 100.
The bottom of wedge block 94 is provided with T-type sliding block 941, and the T-type cooperated with T-type sliding block 941 is offered on mounting plate 11
Sliding slot 110.The cooperation of T-type sliding block 941 is plugged in T-type sliding slot 110, and can be slidably reciprocated, convenient for wedge block 94 in mounting plate 11
On linear movement.
Wherein, head a ball 95 surface is provided with polytetrafluoroethylene ethylene layer.Polytetrafluoroethylene ethylene layer can improve the light on 95 surfaces of heading
Slippery and wear-resisting property are convenient for adjusting, and postpone its service life.
Wherein, pass through shaft 111 or the movable connection of screw between bottom plate 10 and mounting plate 11.Have between the two certain
Free gap.In one embodiment, it is flexibly connected by shaft 111, makes to have between bottom plate 10 and mounting plate 11 certain
Adjustable clearance.
Installation and adjustment component 9 is mainly used for realizing the accurate adjusting of 1 mounting plane degree of detector ontology, guarantees detector sheet
Body 1 is installed horizontal and secured.Specifically, in an advantageous embodiment, installation and adjustment component 9 includes being disposed in an evenly spaced relation in peace
Four groups on 11 4 angles of loading board, so as to facilitate the height for adjusting four angles.Referring to Fig. 3,4 and 5: when needing that detector is turned up
When the right end of ontology 1, pulling plate 17 is first pulled up, will be drawn outside lock pillar 15, so that the arc top flat 16 of 15 bottom of lock pillar is detached from silk
92 surface of bar unlocks screw rod 92；Then rotary turnplate 93 drive screw rod 92 rotate, since nut is fixed, screw rod 92 it is another
End moves linearly to the left, pushes wedge block 94 to be moved to the left by the heading 95 on 92 movable end of screw rod, wedge block 94 supports to the left
Enter in wedge groove 100, the contoured shaped recess with the inner upper wall of wedge groove 100 of wave heave 940 on 94 inclined-plane of wedge block, wedge shape
Block 94 jacks up bottom plate 10, makes the upward micro-displacement of the right end of detector ontology 1, to raise the right end of detector ontology 1, adjusts
Pulling plate 17 is unclamped after good, lock pillar 15 moves down under the pulling force effect of second spring 18, and the arc top flat 16 of lower end presses
On 92 surface of screw rod, locking screw 92 prevents screw rod 92 from rotating, so that the end of high detection instrument ontology 1 is kept fixed；
When needing to turn down the right end of detector ontology 1, pulling plate 17 is first pulled up, will be drawn outside lock pillar 15, to screw rod 92
Unlock；Then turntable 93 is rotated backward, screw rod 92 is driven to move right, wedge block is pulled by the heading 95 on 92 movable end of screw rod
94 move right, and wedge block 94 moves from inside to outside from wedge-shaped Cao, make the downward microbit under self gravitation effect of detector ontology 1
It moves, to turn down the right end of detector ontology 1, pulling plate 17 is unclamped after regulating, passes through 15 locking screw 92 of lock pillar.And entire
In the process, the first spring 13 has the elastic force effect shunk always due to being stretched, and has downwards to the bottom plate 10 of detector ontology 1
Pulling force effect, when turning down detector ontology 1, the pulling force of the first spring 13 is convenient for the return of detector ontology 1；Other first
The pulling force of spring 13 provides pretightning force, fixes detector ontology 1 on mounting plate 11 stronger.
Cooperated by screw rod 92 and nut, screw rod 92 is converted into the horizontal movement of wedge block 94, then pass through wedge shape
The big horizontal position transfer of wedge block 94 is changed into micro- vertical position of the detector ontology 1 of wedge-shaped Cao Chu by block 94 and wedge shape Cao Peihe
It moves, to be able to achieve the accurate adjusting of 1 vertical displacement of detector ontology, guarantees the installation accuracy of detector ontology 1.Wherein, from
And by stroke extension ratio, degree of regulation can be improved；The gradient of wedge block 94 is lower, the degree of regulation of installation and adjustment component 9
It is higher.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
