Abstract

The utility model discloses a top cover type single body air exchanging cage box. The utility model is characterized in that a box cover or a box body is provided with two ventilating pipes, each ventilating pipe is provided with a closed mechanism with a turning plate, the connecting point of the box body and the box cover is provided with a sealing gasket, and the box cover is provided with a filtering film. The utility model is used, fresh and clean air which is filtered by the filtering film can enter a cage box, the stale air in the cage box, which contains NH 3 and CO2 is discharged through the ventilating pipes by an exhaust blower, mutual infection can not generate among cage boxes and between persons and animals. The utility model has the advantages that work environment of operation personnel is improved, investment and operating expense are saved, and the transportation problem of the cage box which loads feeding animals is solved.

Description

Top cap type monomer ventilation cage box

The utility model relates to the cage box of experimental animal, specifically a kind of top cap type monomer ventilation cage box.

Quite a few is open type for the cage box of domestic existing feeding experiment animal, the cage box of this uncovered is placed in the glass cabinet, place again in the desinfection chamber of sealing, need carry out strict purified treatment to the whole test Animal House, correspondingly need dispose the huge Animal House purified treatment control appliance of a cover, cost is very expensive, some belongs to the laminar-flow rack raising cupboard, the cage box that is about to uncovered is seated in the raising cupboard of aseptic purification, requirement to Animal House can correspondingly reduce, but isolate relatively poor between the cage box in the raising cupboard, ventilation in its raising cupboard is distributed in Animal House, the smell is awful to make Animal House, operating personnel's environment becomes very poor, not only the animal in each cage box may infect mutually in the raising cupboard, even may produce human-animal's cross-infection, and the transportation that letting animals feed cage box is housed in addition also is to make us a nerve-racking difficult problem.

The purpose of this utility model is to provide a kind of top cap type monomer ventilation cage box, the air of fresh purification can be sent in this cage box during use, and the interior unpleasant stale air of cage box can be discharged by special pore, can not make animal generation infection mutually in each cage box.

The technical solution of the utility model is achieved in that top cap type monomer ventilation cage box, it mainly comprises box body, be seated in the grid in the box body, be seated in the lid that has grid on the box body, it is characterized in that: on lid or box body, be provided with two ventilation ducts, the closing means that has turnover panel all is installed on each ventilation duct, is provided with sealing gasket, on lid, be provided with filter membrane in the junction of box body and lid.

The utility model is owing to be provided with two ventilation ducts on lid or box body, the closing means that has turnover panel all is installed on each ventilation duct, filtered fresh pure air can enter in the cage box, the stale air that contains NH3 and CO2 in the cage box is discharged from ventilation duct, can not produce mutual infection between each cage box, stale gas in the cage box of discharging from go out air filter in addition can be sent into treating apparatus by pipeline, discharge treated gas outdoor then, can avoid the phenomenon that the smell is awful in the Animal House, improved operating personnel's working environment, also prevented simultaneously that people and animal from producing the possibility of cross-infection, also simplified control appliance greatly, investment and operating cost have been saved, when the cage box of letting animals feed is equipped with in transportation, but the filter membrane air on the lid purifies, the needs of letting animals feed in the cage box that this air that purifies by the filter membrane on the lid can be kept surplus in the of ten hour.
