Problems solved by technology

However, as light perception is the most basic of the three major elements of visual perception, there is no generally accepted model of myopia with photosensitive abnormalities
Therefore, it is impossible to effectively study the correlation between light perception and myopia

Embodiment 1

[0056] A kind of myopia animal model construction apparatus, such as Figure 1-8 , which includes a light board 11 with different color lights, a control structure for controlling the light emission of different color lights on the light board 11; a holding tank 4 for accommodating experimental animals, and an optical mark 31 arranged on the periphery of the holding tank 4; wherein, the light board 11 Be arranged on the top of the holding tank 4, take the holding tank 4 as the center and set the visual mark 31 that is equal to the distance from the outer edge of the holding tank 4 around the holding tank 4; set the screen 5 at the bottom of the holding tank 4; Ventilation holes 7 are arranged structurally; the side walls of the accommodation tank 4 are set as transparent side walls as a whole. The different lamps on the lamp panel 11 are controlled to emit light through the control structure, and the intensity and time of the light are controlled, so as to achieve the effect o...

Embodiment 2

[0068] like Figure 9-12 , on the basis of implementation 1, different sizes of cylindrical rings 3 or accommodating grooves 4 are arranged on a chassis 2, specifically as follows: one low groove 21 and a plurality of low grooves 22 are set on one chassis 2; or set A plurality of low grooves 1 21 and a plurality of low grooves 2 22 are provided correspondingly with receiving grooves 4 and cylindrical rings 3 with different diameters.

Embodiment 3

[0070] like Figure 15 , on the basis of Embodiment 1-2, change the combined structure of the accommodation groove 4, the cylindrical ring 3, the chassis 2 and the lamp panel accommodation top 1, specifically: the chassis 2 is provided with a magnetic ring-23 and A magnetic suction ring 2 24 for placing the columnar ring 3, the magnetic suction ring and the chassis 2 are horizontally arranged, and a magnetically attractive protruding ring 41 corresponding to the magnetic suction ring is set at the bottom of the accommodation groove 4 and the bottom of the columnar ring 3 .

[0071] Different types of chassis 2 are set, and different types of visual marks 31 and cylindrical rings 3 are set correspondingly, and the distance between the visual mark 31 and the accommodation groove 4 is also set to different models, and each chassis 2 is provided with a suction accommodation groove 4. The first magnetic ring 23 and the second magnetic ring 24 absorb and place the cylindrical ring 3...

Abstract

The invention discloses a myopia animal model construction instrument. The construction instrument comprises a lamp panel with lamps in different colors, a control structure for controlling the lamps in different colors on the lamp panel to emit light, a containing groove for containing experimental animals, and sighting marks arranged on the periphery of the containing groove, wherein the lamp panel is arranged at the top end of the containing groove, and the sighting marks with the same distance from the outer edge of the containing groove are arranged around the containing groove with the containing groove as the center; a screen is arranged at the bottom of the containing groove; a vent hole is formed in the structure of the top end of the containing groove; and the side wall of the containing groove is integrally set to be a transparent side wall. Different lamps on the lamp panel are controlled to emit light through the control structure, the light emitting intensity and time are controlled, and the effect of forming a metal animal model by controlling light sensation is achieved. By arranging the screen, discharge of metabolic waste in the model construction process is guaranteed, and the overall air permeability in the model construction process can be guaranteed through the arrangement of the vent hole; and the transparent side wall can ensure that the experimental animal observes surrounding objects at a set distance, and ensures that light rays pass through the transparent side wall.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for constructing a myopia animal model. Background technique [0002] Light is an important natural phenomenon, because the eyes can receive the light emitted, reflected or scattered by objects, so that human beings can see the mottled and ever-changing scenes in the objective world. The visual stimuli obtained by the visual system from nature can be roughly divided into three categories: light perception (perception of object light and shade), form perception (perception of object shape and contrast) and color vision (perception of object color). At present, myopia has become an international problem. To study the principle of myopia formation and the method of treating myopia, it is necessary to construct an animal model of myopia in order to effectively realize the relevant research on the formation principle and treatment of myopia. [0003] Form...
