Abstract
A papillary light reflex model mainly comprises an iris, a liquid crystal screen, a backlight source, a photosensitive element and a singlechip, and is characterized in that the photosensitive element can be used for detecting that light irradiates a pupil, sensing the intensity of light, converting a light signal into an electrical signal and transmitting the electrical signal to the singlechip. The singlechip is used for controlling the lightness and the closing of the liquid crystal screen. The model realizes the change of the diameter of the pupil, which has sense of reality and is more beneficial to vividly explaining by combining the relationship between the change state of the pupil from normal to bigger or smaller and diseases with the degrees of various reflected disease change states. The papillary light reflex model realizes the combination of theory and reality and improves the teaching effect.
Description
Technical field
The utility model relates to the pupil diameter change modeling model that a kind of medical teaching utensil, particularly medical teaching are used.
Background technology
Pupillary light reflex is one of important means of clinical observation change of illness state, in teaching in the past, pupil changes just by oral account, writing on the blackboard or diagram illustrate, even if model people's displaying is arranged, pupil also is static, can not image, reflect that pupil is from normally to the dynamic changing process that enlarges or dwindle realistically, lack of perceptual knowledge, teaching efficiency are not good.
Summary of the invention
The purpose of this utility model is to provide a kind of can reflect the pupillary light reflex model that pupil changes vivid, realistically.
Technical solution adopted in the utility model is: it mainly is made up of iris, liquid crystal display, back light, light activated element, single-chip microcomputer.It is characterized in that it has detected the irradiate light pupil by light activated element, and the power of energy sensing light.Light activated element changes into electric signal with light signal, passes to single-chip microcomputer, the Single-chip Controlling liquid crystal display bright with close.Realize the size variation of pupil diameter.
The beneficial effects of the utility model are, the pupil that model is showed changes realistic, be more conducive in conjunction with pupil from normally to the variable condition that enlarges or dwindle to the relation of pupil and disease and reflect that the light and heavy degree of various change of illness state carries out vivid explanation, realization theory combines with actual, has improved teaching efficiency.
Description of drawings
Accompanying drawing is the synoptic diagram of this structure.1 iris among the figure, 2 liquid crystal displays, 3 back light members, 4 light activated elements, 5 single-chip microcomputers.
Embodiment
Be described further below in conjunction with accompanying drawing.
As shown in drawings, iris 1 is close to liquid crystal display 2, back light 3 be positioned at iris and liquid crystal display under, back light is 2-4cm with the liquid crystal display distance, especially is the best with 3cm.Back light is used to illuminate liquid crystal display.Light source backlight is incandescent lamp bulb, electrooptic panel, light emitting diode or cold-cathode tube, is good with light emitting diode especially.The color of back light is monochromatic, can be for yellow, green, blue, white, especially with yellow best.
Liquid crystal display is the segmentation liquid crystal display that goes in ring, and can show the pupil of different-diameter.
Light activated element also is positioned at the below of iris and liquid crystal display, adjacent back light.Be used to detect the light source that shines the iris surface.
Light activated element can be experienced light source, and according to the power of light source, sends different electric signal, passes to single-chip microcomputer, the switching of single-chip microcomputer internal program control liquid crystal display.When intense light source shone the pupil model, annular minimum on the liquid crystal display was opened, and on the promptly visible iris pupil that dwindles was arranged; Intense light source is left, and under the ordinary ray situation, intermediate annular is opened on the liquid crystal display, and the pupil of normal size is arranged on the promptly visible iris; When light source was more weak, outer annular was opened on the liquid crystal display, the promptly visible big pupil that looses.
The above, only being the utility model preferred embodiment, is not that the utility model is done any pro forma restriction, and all foundations technical spirit of the present utility model is to any simple modification that above embodiment did, equivalent variations and modification still belong in the scope of technical solutions of the utility model.
