Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an animal rearing device for raising experimental animals in a constant and favorable environment suitable for research.

(Prior Art) As shown in FIG. 3, in a conventional animal breeding apparatus, a breeding rack 22 is installed in a breeding room 21, a breeding container or a wire mesh cage is placed on this breeding rack 22, and then the breeding room is opened. Clean air was forced into the air outlet 21 through the outlet 23. The breeding rack 22 was installed without strictly considering the distribution of airflow within the animal breeding room 21 (indicated by arrows in FIG. 3). In FIG. 3, 24 indicates air supply, and 25 indicates exhaust air.

(Problem to be solved by the invention) However, in such animal breeding equipment, clean air and contaminated air that has passed through the breeding container or wire mesh cage are mixed and circulated inside the room.
This method had the disadvantage that dust, bacteria, ammonia, etc. were generated indoors, deteriorating the environment for the experimental animals and the breeding workers. In addition, the air supplied into the breeding container or the wire mesh cage is contaminated, resulting in a deterioration of the breeding environment for the experimental animals.

This idea was made in view of the above circumstances.
By quickly exhausting contaminated air,
Contaminated air is not mixed with the clean air flowing into the room, creating a comfortable working environment.
In addition, by supplying clean air into the rearing container or wire mesh cage, and controlling the flow rate of air passing through the rearing container or wire mesh cage to optimize the airflow, there is no microbial contamination among experimental animals, and ammonia stagnation is prevented. To provide an animal breeding device capable of creating a good breeding environment with little flow.

(Means and effects for solving the problem) In order to achieve the above object, the present invention provides a retentate chamber that is separated from a working room and ventilates the air in the working room, and a method that allows the back of the retentive chamber to be easily removed. a rearing rack that is connected to the rear opening in the work chamber, a rising board that is provided so that its upper part opens to the rear opening of the rearing rack, and a raised plate that closes the upper part to the front opening of the rearing rack. The system is characterized by a hanging curtain installed in a manner that allows the contaminated air that has passed through the rearing containers or wire mesh cages installed in the rearing rack to be quickly exhausted, thereby reducing the amount of clean air flowing into the room. It is possible to create a comfortable working environment free of allergies and odors by preventing contaminated air from being mixed with fresh air, and to supply clean air into the rearing container or wire mesh cage, as well as the air passing through the rearing container or wire mesh cage. By controlling the air volume and optimizing the air flow, it is possible to create a good breeding environment that is free from microbial contamination among experimental animals and has little ammonia stagnation.

(Examples) Examples of the present invention will be described in detail below with reference to the drawings.

1 and 2 show an embodiment of the present invention,
Reference numeral 1 denotes a work room 1 in which a rearing worker works, and an adjacent part of this work room 1 is provided with a lettuce chamber 3 partitioned by a descending wall 2 or the like. In the working room 1, there is a rearing rack 4 with its back attached to the lettuce chamber 3.
and are connected to each other in a manner that is easy to remove. A rising plate 5 made of, for example, stainless steel is provided at the back opening of each shelf of the rearing rack 4, with a slit-shaped opening at the top, and at the front opening of each shelf of the rearing rack 4, for example. A banner 6 made of antistatic vinyl chloride sheet or the like is provided with the top closed. A breeding container or a wire mesh cage is installed on each shelf of the breeding rack 4. An air inlet 7 is provided at the upper part of the working chamber 1 . In FIGS. 1 and 2, arrows indicate airflow distribution, arrow 8 indicates air supply, and arrow 9 indicates exhaust air.

That is, the worker enters the work room 1 and enters the rearing rack 4.
rearing animals in breeding containers or wire mesh cages set up in In this case, the retentate chamber 3 only needs to have a space for evacuation and does not require a space for a worker to enter, so the space of the work room 1 can be increased accordingly, and efficient work can be realized.

In addition, the animal breeding room is forcibly ventilated. That is, an exhaust device such as a fan is connected to the retentate chamber 3, and as a result of forcibly exhausting the retentate chamber 3, fresh air enters the work chamber 1 from the air inlet 7, and the inside of the work chamber 1 is Fresh air flows into the lettuce chamber 3 through breeding containers or wire mesh cages installed on each shelf of the breeding rack 4 and is exhausted to the outside. In this case, the suction air volume can be controlled by the rising plate 5 provided on the rearing rack 4, and the hanging curtain 6 can prevent the atmosphere inside the rearing rack 4 from flowing into the work room 1, so that the airflow can be properly controlled. can be converted into
Therefore, a good breeding environment can be created. The height of the rising board 5 is preferably 11/12 of the height of each shelf of the breeding rack 4, and the height of the banner 6 is preferably 1/3 of the height of each shelf of the breeding rack 4.
For example, if the height of the rearing rack 4 is 30 cm, the height of the rising board 5 is 27.5 cm, and the height of the banner 6 is
Just make it 10cm.

In addition, by quickly exhausting contaminated air that has passed through the rearing containers or wire mesh cages installed in the rearing rack, the contaminated air will not be mixed with the clean air flowing into the room, thereby preventing allergic reactions. , creating an odor-free and comfortable working environment.

Furthermore, by supplying clean air into the breeding containers or wire mesh cages, we can create a good breeding environment with significantly less microbial contamination among experimental animals and less ammonia stagnation than in the past. I can do it.

In addition, when ventilating the work room 1 as shown in FIG. There was a risk that the air flowing into the farmed animals and contaminated by the workers could infect the farmed animals. Therefore, fresh air may be introduced from the rearing chamber 3 and contaminated air may be discharged from the air inlet 7. In this way, fresh air can be transferred to the rearing containers installed in the rearing rack 4 or It can be supplied to animals kept in wire mesh cages, reducing the risk of infection of the animals by workers.

It is a stop plate.

(Effects of the invention) As described above, according to the invention, by quickly exhausting the contaminated air that has passed through the rearing container or wire mesh cage, the contaminated air is absorbed into the clean air flowing into the room. It is possible to create a comfortable working environment free of allergies and odors without mixing, and to supply clean air into the rearing container or wire mesh cage, and to control the air flow through the rearing container or wire mesh cage. By optimizing the flow, it is possible to provide an animal breeding apparatus that can provide a favorable breeding environment in which microbial contamination among experimental animals is much less than in the past, and ammonia stagnation is also small.
