Description
Technical field
The utility model belongs to field of bioexperiment technology, is related to a kind of closed feeding system of overhead type experimental animal.
Background technology
Experimental animal can be divided into level Four by laboratory according to experimental animal control of microorganisms standard, be respectively conventional animal,
Clean animal, specific-pathogen free animal, sterile or lively thing of dwelling.Wherein specific-pathogen free animal (Specific
Pathogen Free, SPF), it is desirable to the cause of disease for excluding Amphixenosis and animal Infectious Diseases is external, also to exclude
Defined pathogen.SP typically requires 10,000 grades of air purity requirement, is current most popular experimental animal both at home and abroad,
Its source, both may be from the descendant that germfree animal breeds, after can also being taken through cuing open tire, in the environment of isolation barrier facility, by
SPF parental animals are fostered.It is without the microorganism caused a disease in itself to human or animal, but can not exclude can be vertical through placental barrier
The microorganism of propagation.
SPF animals are general first to be cultivated after germfree animal or gnotobiotic animal mostly, then it has been moved on in closed system facility
Feeding is gone to breed.Independent ventilating cage (Individual Ventilated Cages, IVC) refers in closing separate unit (cage box
Or cage tool) in, clean air is sent into, by what is emitted in exhaust gas centralized, SPF experiments can be operated and raise in superclean bench
The raising of animal and experimental facilities.Cultivation, breeding, conservation and all kinds of short-term zooperies of the suitable SPF animals of independent ventilating cage,
Be particularly suitable for use in raising immunodeficient animals and transgenic animals.Compared with the barrier environment of laboratory animals, with it is easy to operate,
The saving energy, equipment maintenance cost are low and require low advantage to room.
Independent ventilating cage is made up of main frame, ventilation cage and the part of sealing cage box three.Room air is through powered air-purifying system
Each individually sealing cage box on into air-guiding aisle cage.For SPF animals provide uniformly, low flow velocity pure air, animal
The waste gas of discharge enters main frame exhaust system through cage return air duct, then is discharged into after filtering outdoor.So as to keep cage box
Interior low ammonia density and humidity, reduction bedding and padding replacement frequency, effectively prevent animal cross-infection, ensure that experimental work personnel's is strong
Health and safety.
Independent ventilating cage is used in the prior art main frame discrete and the class of overhead type two, are to provide the clean fresh air of animal simultaneously
Outdoor will be emitted into after air filtration after being replaced in cage, it is ensured that the key of relatively low ammonia density and fresh clean environment in cage box
Equipment.However, vertical main frame occupies larger space, it is all difficult to carry out with the connection of independent ventilating cage and the setting of air flue
Modularized production.And depending on overhead type main frame of the prior art is generally according to cage size, length and width is as cage, height
Depending on electrical equipment and filter.Due to cage multi-size, the production for overhead type main frame causes delayed, is also unfavorable for
Stock production, without versatility, it is impossible to standardized production.
The size of overhead type main frame is than larger, weight weight in the prior art.Due to being tested in whole big cabinet, influence cage
The daylighting of animal.When device fails, because overhead height of main frame is more than the height of human body, cause overhead maintenance not side
Just.The present invention is therefore.
The content of the invention
