Description

Guinea pig form sensation deprivation eye cover

Technical Field

The utility model relates to a cavy form-sense deprivation eye patch, which belongs to the field of animal form-sense deprivation myopia model construction.

Background

In experimental myopia research, in order to understand the occurrence mechanism of myopia, an experimental mode of constructing an animal experimental myopia model is generally adopted, and chickens, mice, monkeys, guinea pigs and the like are generally selected as the model. At present, guinea pigs become a good model organism for myopia-related research commonly adopted at home and abroad, and the current method for inducing experimental myopia models of guinea pigs is mainly a 'form-sense deprivation' method, including an eye-shade method. However, the eye-shade method has the defects that the wearing tightness of the eye shade is not easy to adjust, the activity of the guinea pig is affected, and the like. Aiming at the problems, through search, the Chinese invention patent is as follows: the utility model provides a mouse myopia model induces instrument (application number is 200910154157.9, and the application date is 2009 11 month 6 days), and this application discloses a mouse myopia model induces instrument, including rectangular eye-shade, the eye-shade is made by nontoxic, the plastic slab that has certain plasticity, the forward deflection of eye-shade top edge corresponds the department to mouse nose side, the eye-shade top edge extends backward to the auricle rear that corresponds the mouse to correspond the department and seted up first breach at the auricle of mouse, the eye-shade is equipped with the opaque hemisphere of an outside carina process in mouse eyeball correspondence department the second breach has been seted up corresponding to under the opaque hemisphere on the lower limb of eye-shade, and the top of this second breach communicates with each other with the inner chamber of opaque hemisphere. Has the advantages of light wound, safety, low cost and difficult shedding. However, the disadvantages of this application are: the invention needs to be sewed on the skin of the mouse through a suture, inevitably causes certain damage to the mouse, and simultaneously has a complex sewing process and is easy to cause the infection of the mouse, thereby influencing the experimental result.
