It provides a comfortable working environment without allergies and odors.

Further, by supplying clean air into a breeding container or a wire netting cage, it is possible to create a favorable breeding environment in which microbial contamination between experimental animals is far less than before and there is little ammonia retention. Can be.

[0007]

The conventional animal breeding apparatus of the one-way flow system creates an air flow from the front to the rear of the rack and ventilates the inside of the rack. If a pathogen emerged in the side working area, it would always pass through the rack and contaminate the experimental animals.

In the case of a positive pressure type rearing rack (rear air supply and front exhaust), the environment for dust and odor in the working area is deteriorated. Also, in the case of the conventional rear air supply, a vortex is generated in the upper part of the air supply area due to the dynamic pressure of the air flow supplied from the duct connected to the air supply area (air supply chamber), and a part of the pressure is reduced. The amount of air supply tended to decrease, and uniform air supply was difficult.

The present invention has been made in view of the above circumstances, and since the door is folded and opened and closed, the door does not become an obstacle in the animal breeding room, and the opening is made large so that the breeding rack can be easily taken in and out. It is an object of the present invention to provide an animal breeding apparatus that can maintain a high degree of cleanliness in a rack, can better maintain a work environment in a work area on a passage side, and can evenly distribute air supply in an air supply area.

[0010]

In order to achieve the above object, an animal breeding apparatus according to the present invention is an animal breeding apparatus in which an animal breeding room is divided by a door into a breeding area on a breeding rack installation side and a work area on a passage side. The door comprises a door body configured to open and close while being folded, and a support member that supports the door body to be freely opened and closed by an upper guide and is detachably attached to the door body. Is what you do.

FIG. 3 is an explanatory plan view showing an example of the door 14, and FIG. 4 is an explanatory side view showing an example of the door 14. That is, one breeding rack 20 in the animal breeding room
A cylindrical guide member 33 is provided between the columns 31 and 32 corresponding to the width in which is stored.
The support members 34 and 35 are attached so as to be movable in the axial direction. Each of the support members 34 and 35 is an L-shaped member 3.
The ring members 342 and 352 are integrally provided on one outer surface of the ring members 41 and 351, and the guide member 33 is loosely inserted into the ring members 341 and 351 and attached. Further, two door bodies 36 and 37 are provided between the pillars 31 and 32, respectively.
It is mounted to close the opening between the two. Each of the door bodies 36, 37 has one of its side edges at the pillar 31,

By attaching to the 32 with a hinge (not shown),
It can be folded and attached. Each of the door main bodies 36 and 37 is provided so as to be freely bent at a central vertical line. In this case, for example, each of the door bodies 36 and 37 can be provided so as to be freely bent at the central vertical line by cutting the central portion at a vertical line and attaching the cut portion with a hinge (not shown) or the like. The L-shaped members 341 and 35 of the support members 34 and 35 are provided on the work area 11 side above the other side edges of the two door bodies 36 and 37, respectively.
The other outer surfaces of the ones are respectively removably mounted.

That is, the animal breeding apparatus is divided into a work area 11, a breeding area 15, and an air supply area 24. The air supply 28 to the breeding rack 20 is provided to each shelf of the breeding rack 20 by supplying clean air from a fine mesh of a duct-like bag 27 made of a fine synthetic fiber cloth in the air supply area 24. Uniform air supply can be performed. On the ceiling of the breeding area 15, an exhaust port of an exhaust duct 18 is provided, and an air supply area 24 is provided.
From the breeding rack 20 is exhausted. The supply and exhaust of the work area 11 are performed by an air supply port 12 and an exhaust port 13 in the work area 11. The breeding area 15 and the air supply area 24 are separated by an escape-preventing wire mesh 22 to prevent experimental animals that escaped from the breeding container or the wire mesh cage from entering the air supply area 24. In the front of the breeding rack 20, a raising plate 23 is raised to prevent the experimental animal escaped from the breeding container or the wire mesh cage from going out of the breeding rack 20. The start-up plate 23 is provided with a gap at an upper portion to serve as an exhaust port for exhausting the air in the rearing rack 20.

As described above, by providing a door at the boundary between the breeding area and the work area in the animal breeding room to partition the environment, the respective environments can be maintained at a high level. Further, by folding the door structure, the door structure can be simplified. In addition, by using a cylindrical guide member for the guide of the door, it is possible to reduce dust accumulation and easily wipe off dirt. In addition, since no protrusion is provided on the floor of the animal breeding room, the rearing rack can be moved without any trouble. Because the door is folded and opened and closed, the door does not become an obstacle in the animal breeding room, and the opening can be made large, so that the breeding rack can be easily taken in and out. In addition, since the support member has a structure detachable from the door, the door can be opened without being folded during cleaning.

Further, clean air is supplied from the air supply area to the rearing rack by the air supply to the rear side of the rearing rack, so that the cleanliness in the rearing rack can be maintained at a high level. In this case, the air supply in the air supply region can be made uniform in the vertical and horizontal directions of the air supply to the breeding rack by passing the air through a duct-like bag made of fine synthetic cloth. Since the pressure loss between the air supply area and the breeding area exhaust port is small, even if the breeding rack is partially removed, there is no disturbance in the air balance. Since the air supply area on the rear side of the rearing rack is a clean area, dirt is reduced, and the frequency of management work in this part where cleaning and sterilization is most difficult can be reduced.

Further, since the working area and the breeding area are separated by the transparent glass door, the degree of contamination of the worker and the working area does not affect the cleanliness in the breeding rack. On the other hand, the air in the rearing rack is exhausted from the front side of the rearing rack, but the breeding area and the work area are separated by a transparent glass door, so that the odor and dust generated from the experimental animals do not stay in the work area. The environment can be better maintained. The work environment is improved by taking measures to allergic workers and eliminating discomfort caused by odors.

Furthermore, since the rear of the rearing rack is partitioned by a wire mesh for preventing escape and the front of the rearing rack is partitioned by a rising plate, even if the experimental animal escapes from the rearing container or the wire mesh cage, there is a possibility that the experimental animal will escape from the rearing rack. Absent. Genetically modified animals that have come into use in recent years must prevent the escape of laboratory animals in consideration of safety to the ecosystem and the environment.

[0018]

As described above, according to the present invention, since the door is folded and opened and closed, the door is not obstructed in the animal breeding room, the opening is made large, and the breeding rack can be easily taken in and out. It is possible to provide an animal breeding apparatus that can maintain a high degree of cleanliness inside, can maintain the work environment in the work area on the passage side better, and can evenly distribute the air supply in the air supply area.
