Description
Technical field
This utility model relates to aspheric surface stimulates screen, belongs to medical instruments field.
Background technology
Stimulate the eyeball of screen for stimulating people, be widely used in the treatment of various eyes and detect on medical apparatus and instruments, as for visual field instrument, visual field instrument is used to a kind of important Medical Instruments of monitoring the human eye visual field, it detects the visual field of patient by the position and light intensity being distributed in the stimulation point in dome-type screen by random order conversion, be widely used in glaucoma, eye hypertension, pigment dispersion syndrome, the perimetry of the multiple ophthalmic diseases such as false exofoliation syndrome, also be the important means of neurosurgery for nervous system disease early diagnosis, being admitted to of professional driver's driving license abroad, the health check-up of pilot, it is all important indicator that the visual field is detected.
Simultaneously also with detecting the aspect such as glaucoma, color-aware ability.General stimulation screen is spherical stimulation screen, and cost is high, and volume is large, complex structure.
Summary of the invention
In view of this, this utility model provides aspheric surface stimulates screen, and structure is simple, and cost is low, compact structure, uses and convenient transportation.
This utility model is solved the problems of the technologies described above by following technological means:
Aspheric surface of the present utility model stimulates screen, comprise governor motion, transmission mechanism and stimulate screen, described governor motion comprises focus adjusting mechanism and dimming mechanism, described dimming mechanism is connected with transmission mechanism, described transmission device front end is provided with delineascope, described stimulation screen bottom is provided with the mobile chin rest, the described mobile chin rest is provided with correction mirror holder, the described mobile chin rest is connected with upper volume holder, described correction mirror holder and upper volume holder are all positioned at stimulates screen, described stimulation screen is tubular face, and described focus adjusting mechanism is connected with dimming mechanism.
Further, described delineascope is shielded relative with stimulation, and transmitted ray projects by delineascope to stimulate on screen.
Further, described governor motion is positioned at stimulates screen top, and described transmission mechanism extend into stimulate in screen.
The beneficial effects of the utility model: aspheric surface of the present utility model stimulates screen, structure is simple, and cost is low, compact structure, uses and convenient transportation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is structural representation of the present utility model.
In figure: 1, governor motion, 2, transmission mechanism, 3, stimulate screen, 4, focus adjusting mechanism, 5, dimming mechanism, 6, delineascope, 7, the mobile chin rest, 8, correct mirror holder, 9, Shang Etuo.
Detailed description of the invention
Below with reference to accompanying drawing, this utility model is described in detail, as shown in Figure 1: the aspheric surface of the present embodiment stimulates screen, comprise governor motion 1, transmission mechanism 2 and stimulation screen 3, described governor motion 1 comprises focus adjusting mechanism 4 and dimming mechanism 5, described dimming mechanism 5 is connected with transmission mechanism 2, described transmission mechanism 2 front end is provided with delineascope 6, described stimulation screen 3 bottom is provided with the mobile chin rest 7, the described mobile chin rest 7 is provided with and corrects mirror holder 8, the described mobile chin rest 7 is connected with upper volume holder 9, described correction mirror holder 8 and upper volume holder 9 are all positioned at stimulates screen 3, described stimulation screen 3 is tubular face, described focus adjusting mechanism 4 is connected with dimming mechanism 5.
As the further improvement of technique scheme, described delineascope 6 is relative with stimulation screen 3, and transmitted ray projects by delineascope 6 to stimulate on screen 3.
As the further improvement of technique scheme, described governor motion 1 is positioned at stimulates screen 3 top, and described transmission mechanism 2 extend into stimulate in screen 3.
Owing to adopting the stimulation screen in tubular face, whole stimulation screen is in short cylindrical shape, compact, avoid the spherical difficulty of screen processing that stimulates large simultaneously, reduce cost, also facilitate transport, focus adjusting mechanism 4 is for focusing, dimming mechanism 5 is for adjusting light intensity, and then light is projected by the delineascope 6 of transmission mechanism 2 stimulates on screen 3, realizes the function that light stimulates.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
