A kind of pupillary movements measuring device
Technical field
This utility model relates to a kind of medical treatment device, particularly a kind of bilateral pupillary movements measuring device.
Background technology
Eye is the human body vitals.The people is when the embryo, and eyes are extensions of brain.Along with growing differentiation, eye just shifted out outside the cranial cavity afterwards.But in fact eyes are still the mirror of brain.The doctor often sees through the variation that this fan fenestella of pupil is spied on the optical fundus, diagnoses the disease of brain.The arteriosclerosis on optical fundus means cerebral arteriosclerosis, and optical fundus optic nerve swelling shows cerebrocellular edema and pointed out the brain borough chief indirectly tumor.The size of bilateral pupil aperture can be reacted some vital functions and genius morbi.
The aperture of pupil is subjected to the adjusting of higher nervous activity and changes.Pupil can dwindle automatically when light was dazzling, then can hold again greatly when dark, was called the light reflex of pupil.During rayed one side pupil, this side pupillary light reflex is called direct light reflex, and an other side pupil also can light reflex occur simultaneously, is called indirect light reflex.
Pupillary light reflex is a kind of reflexive involuntary movement, can relatively accurately estimate the nervous system situation objectively.The dynamic change of pupil aperture can reflect higher nervous activity and physiological status thereof.Bilateral pupillary light reflex situation can be reacted some vital functions and genius morbi, in fields such as diagnosing the illness, detect the state of an illness, pharmaceutical properties research, spiritual psychology wide application space is arranged.The objective pupillary light reflex that detects quantitatively becomes the problem that clinical ophthalmology, department of neurology, spiritual shrink are faced.
Pupil also can present different shapes under some particular cases, such as, the iris damage.Therefore provide the exact image of pupil to help medical diagnosis.In the prior art, also do not have can the quantitative measurement pupillary light reflex instrument.This is for medical application, describing pupillary light reflex can only be with sensitive and blunt the description, can not objectively respond the variation of pupillary light reflex well, and this has also just limited to the application that pupillary light reflex reflects itself and disease relationship.
Therefore, just need a kind of device that can the dynamic change of quantitative measurement pupil aperture, can provide more precise diagnosis data for clinical ophthalmology, department of neurology, spiritual Psychology Dept..

Description of drawings
Fig. 1 is the sketch map of this utility model one embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is described in further detail:
As shown in Figure 1, make the bilateral pupil dynamic measurement device of present embodiment, whole device is divided into inspection box 1 and computer installation 2 two parts are formed by connecting.
Comprise a light source 10 in the inspection box 1, this light source 10 is such as being the light supply apparatus that sends infrared light; First photographic head 11 and second photographic head 12 are connected with image processing apparatus 13 in the computer installation 2, this first photographic head 11 and second photographic head 12 are such as being to infrared light activated infrared camera or responding to infrared ultra-low illumination photographic head that for example minimal illumination is the photographic head of 0.0003lux (lux); Be two in the back of first infrared camera 11 and second infrared camera 12 and independently sting lasing light emitter, be respectively the first thorn lasing light emitter 14 and the second thorn lasing light emitter 15, provide and detect needed basic brightness, make the eye pupil size of testee keep moderate.The first thorn lasing light emitter 14 and the second thorn lasing light emitter 15 are connected with light source control device 16 in the computer installation 2; Infrared light supply 10 is connected with light source control device 16 in the computer installation 2; First eyepiece 17 and second eyepiece 18 are installed in first infrared camera 11 and second infrared camera, 12 fronts respectively; Inspection box 1 is the totally enclosed type inspection box, and two eyeshields are arranged foremost, the alignment of measured's eyes is placed in the eyeshield, thereby measured's eyes is not influenced by extraneous light when test.Two eyeshield back respectively to its ground corresponding first eyepiece 17 and second eyepiece 18.First photographic head 11 and second photographic head 12 are to be installed in movably on the base plate of inspection box 1 in inspection box 1, the position of the win photographic head 11 and second photographic head 12 can be regulated, so that imaging effect is best with respect to first and second eyepieces, 17,18 front and back.In the horizontal direction, infrared light supply 10 is mounted in the rear portion of inspection box 1, and makes the position height of infrared light supply 10 to the first and second thorn lasing light emitters 14,15 on the vertical direction, makes infrared light supply 10 do not blocked by two thorn lasing light emitters.
Computer installation 2 is made up of main frame, display, keyboard, mouse, printer that inside comprises light source control device 16 and image processing apparatus 13.Be used to show that the display 19 of measurement result is connected with image processing apparatus 13; The input block 20 that is used to import is connected with image processing apparatus 13, and this input block 20 is keyboard and Mus mark; Printer 21 is connected with image processing apparatus 16.Below each parts are elaborated:
First photographic head 11 and second photographic head 12 are the infrared cameras to infrared ray responsive, or respond to infrared ultra-low illumination photographic head, and its minimal illumination is such as being 0.0003lux.
The first thorn lasing light emitter 14 and the second thorn lasing light emitter 15 to person under inspection's eyes are separately independently, and stimulus modelity can be selected by light source control device 16 according to clinical needs, stimulate simultaneously such as eyes, or alternately stimulate etc.The irradiation light intensity of thorn lasing light emitter is such as 1cd (candela), and the thorn lasing light emitter adopts white light, and those skilled in the art should know the monochromater that also can adopt different frequency according to clinical needs, or the light source of the monochromatic mixed light of several characteristic frequency.In the present embodiment, right and left eyes is accepted source stimulating separately, is independent of each other.
