Abstract
The utility model relates to a retinal light injury experiment box used for researching rat retinal light injury experiment models and belongs to the field of medical experiment equipment of ophthalmology. The experiment box comprises a square box body with equal length and width, a split type door is arranged on the top side of the box body, a plurality of cooling holes are arranged on the left, right and back sides of the box body, a fan hole is arranged in the center of the front side of the box body, a fan is embedded in the fan hole, white fluorescent lamps are arranged on the inner wall of the door, the inner wall of the left side, the inner wall of the right side and the inner wall of the back side respectively, and a plurality of transparent gratings are arranged in the inner cavity of the box body and divide the inner cavity into a plurality of sub-cavities. By aid of the retinal light injury experiment box, experimental rats are placed in the sub-cavities of the box body, strong visible light irradiation is performed on the rats in the box body through the fluorescent lamps to induce the retinal injuries of the rats. The retinal light injury experiment box is simple in structure and convenient to operate and control, and provides basis for retinal injury research and pathological change mechanism in the ophthalmology field.
Description
Technical field
This utility model relates to ophthalmology medical experiment device field, particularly a kind of retina photodamage experimental box that is used to study the retinal photic injury in rats experimental model.
Background technology
Natural light and artificial light sources all are the potential threats of retina injury, and for many years, retina photodamage pathology is an important research project of field of ophthalmology with control always.In recent years, along with the opticianry medical instruments use increasing, people are not only to natural light, and various opticianry medical instruments light sources and the problems such as retina injury that cause thereof are carried out more deep research.Retina regression mechanism and etiological diagnosis thereof and treatment are a difficult problem of ophthalmic industry for many years always, still, still do not have the consistent animal model that is used for studies of generally acknowledging at present.
The utility model content
This utility model provides a kind of retina photodamage experimental box to the problem that prior art exists, and aims to provide the stronger visible light of a kind of employing and sets up the retina photodamage animal model, with the origin cause of formation of research retina photodamage and retina regression.
The purpose of this utility model is to realize like this; A kind of retina photodamage experimental box; Comprise the square box that length and width equate, said box top is provided with the door of splitting, and said casing left surface, right flank and trailing flank are provided with some louvres; The leading flank center of casing is provided with fan hole; Be embedded with fan in the said fan hole, the inwall of said cabinet door, left surface inwall, right flank inwall and trailing flank inwall are equipped with white daylight lamp respectively, and cabinets cavity is provided with some transparent grid screens inner chamber is separated into some minutes cavitys.
Adopt the experimental box of this utility model, will test with rat and place in the case cavity of intravital each minute, the rat of cabinets cavity is carried out strong radiation of visible light intermittently, induce rat retina to damage with daylight lamp.Therefore, the experimental provision of this utility model is simple in structure, and operation and control are convenient, for ophthalmic industry research retina injury and pathological changes mechanism provide foundation.
As the optimal way of this utility model, said casing is wooden, and inwall pastes white paster.
Another kind as this utility model is preferred, and the length of said casing * wide * height is of a size of 1m * 1m * 0.5m.
For making case cavity illumination of intravital each minute even, said transparent grid screen is the colourless transparent resin glass plate, thickness of slab 5mm, and dividing the quantity of cavity is 16.
For guaranteeing the casing heat dispersion, said heat radiation aperture is 2cm, evenly concentrates each lateral center that is distributed in for every each 30.
As the another optimal way of this utility model, the power of said daylight lamp is 30W, and fluorescent tube length 90cm is provided with at each sidewall between two parties.
For ease of the installation of fan, make to have better heat radiating effect in the casing, said fan hole diameter is 20cm.

Fig. 2 is the casing figure of this utility model.
Fig. 3 is the grid figure of this utility model.
Wherein, 1 casing; 2 flase floors; 3; 4 daylight lamp; 5 right flanks; 6 leading flanks; 7 fan hole; 8 trailing flanks; 9 left surfaces; 10 louvres.
The specific embodiment
As shown be the retina photodamage experimental box of this utility model; Comprise the square box 1 that length and width equate; Casing 1 end face is provided with the door of splitting 3; Casing left surface 9, right flank 5 and trailing flank 8 are provided with some louvres 10, and leading flank 6 centers of casing 1 are provided with fan hole 7, are embedded with fan in the fan hole 7; The inwall of cabinet door 3, left surface inwall, right flank inwall and trailing flank inwall are equipped with white daylight lamp 4 respectively, and casing 1 inner chamber is provided with some transparent grid screens 2 inner chamber is separated into some minutes cavitys; Among the embodiment, casing 1 is wooden, and inwall pastes white paster; The length of casing 1 * wide * height is of a size of 1m * 1m * 0.5m; The transparent grid screen is the colourless transparent resin glass plate, thickness of slab 5mm, and dividing the quantity of cavity is 16; Louvre 10 diameters are 2cm, evenly concentrate each lateral center that is distributed in for every each 30; The power of daylight lamp 4 is 30W, and fluorescent tube length 90cm is provided with at each sidewall between two parties; Fan hole 7 diameters are 20cm.
Adopt the retina photodamage experimental box of this utility model; Can be with the dark adaptation 24 hours under fully unglazed environment of many experimental rats; Set up preceding 30 minutes of model with 1% atropine liquid mydriasis 1 time; After the photic damage case was turned on light 15 minutes rat put into each minute cavity of casing 1 respectively, carrying out high light stimulates; The SD rat is taken out in illumination after 6 hours, put under the ordinary ray environment, observes rat retina outer nuclear layer thickness impairment degree after 7 days.Adopt this device, can use different illumination intensity and light application time to observe rat retina outer nuclear layer impairment degree, for human ophthalmology pathological study provides experimental basis.
This utility model is not limited to the foregoing description; For example, cabinet door can be the form of the non-whole fan door of splitting, and the size of casing and number of cavities can according to actual needs and suitably change; Tank material also can be other nonmetallic materials such as plastics; The power of daylight lamp can change the variation that light intensity in the casing requires according to experiment, and in a word, those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the scope of this utility model protection.
