Description

[Detailed description of the invention] [Industrial application field] This invention relates to an animal breeding room suitable for use in a laboratory animal breeding facility for obtaining animal experiment data as a preclinical test.

[Conventional technology]

To confirm the efficacy and safety of various drugs,
Animal administration experiments as preclinical tests are extremely important. Experimental animals are kept and managed in special animal breeding experimental equipment.

The experimental facility is equipped with twin walls to ventilate, clean, and sterilize the animal room. FIG. 1 is a sectional view of the main parts of an example of a conventional twin wall, showing a rearing room 10 and a partition wall 1.
A twin wall main body 14 for isolating the breeding room 10 and ventilating the room is provided between the two. Air suction ports 16 with prefilters are provided at a plurality of locations on the twin wall main body 14, so that contaminated air within the rearing room 10 is exhausted from a duct 18 through a flow path indicated by an arrow.

The reason why a plurality of suction ports 16 are provided is to prevent contaminated air from circulating inside the breeding room 10 and staying inside the room.

The twin wall main body 14 is fixed to the ceiling and floor of the breeding room 10. In the illustrated example, a baseboard receiving plate 24 is attached to a U-shaped floor base 22 attached to a floor surface 20, and the upper end of this baseboard receiving plate 24 is attached to another U-shaped floor base. 22 with screws or the like.

The twin wall main body 14 is moved so as to come into contact with the baseboard retainer 26 attached to the upper end of the baseboard receiving plate 24.
In this state, the lower part of the twin wall main body 14 is attached and fixed to the floor base 22 located above with screws 28.

In addition, 30 is a waterproof flooring material.

The upper part of the twin wall main body 14 is attached to an inverted U-shaped ceiling base 34 fixed to the ceiling 32, and the entire twin wall main body 14 is fixed.
36 is the ceiling base.

Now, like this, the conventional twin wall body 1
4 is fixed to the ceiling 32 and floor 20, which not only makes it difficult to regularly clean and disinfect the interior of the breeding room 10 in which the twin wall main body 14 is installed, but also prevents the twin wall main body 14 from being attached to the suction port 16. To replace the filter, a person who is likely to be a source of contamination must directly enter the breeding room 10 and replace it.
It was not possible to maintain a cleanliness level within 0.

[Purpose of invention]

In consideration of the above facts, this invention makes it possible to easily perform regular cleaning and disinfection inside the breeding room, and also cleans and disinfects the twin walls themselves in the adjacent room (front room or back room) outside the breeding room. To provide an animal breeding room in which the breeding room can be kept at a high level of cleanliness.

[Summary of the idea]

The animal breeding room according to the present invention achieves the above object by configuring the twin wall main body in a movable manner.

[Example of idea]

FIG. 2 shows a first embodiment of the animal breeding room according to the present invention, and this embodiment has movable means provided on the upper surface of the twin wall main body 14.
This is a case in which it is configured in a hanging type. That is, L-shaped hangers 40 as shown in the figure are attached to at least two places on the upper end side surface of the twin wall main body 14, and a roller attachment member 42 is attached to the upper bent piece 40a of this hanger 40. A roller 44 is rotatably supported on 42 with its axis being horizontal.

The roller 44 is rotatably engaged with a single guide rail 46 attached to the ceiling 32. Therefore, a slit 48 is formed in the center of the lower surface of the guide rail 46 so that the mounting portion 42 can be moved.

Incidentally, the reference numeral 50 is used to prevent the twin wall main body 14 from lateral vibration when it is moved along the guide rail 46, and to close the gap between the twin wall main body 14 and the ceiling.

On the other hand, the lower end of the twin wall main body 14 has a U
A letter-shaped engagement recess 52 is provided, and a floor guide rail 54 that also serves as a bottom plate is provided with which the engagement recess 52 engages. In this example, a crank-shaped guide rail is used, one end of which is fixed to the partition plate 12. The reason why the floor guide rail 54 is fixed to the partition plate 12 while floating from the floor surface 20 is to take cleaning of the floor surface 20 into consideration.

FIG. 3 is a schematic plan view of a breeding room 10 to which the present invention is applied, and twin wall bodies 14 are attached to both sides of the breeding room 10 partitioned by a partition plate 12. A plurality of twin wall bodies 14 having a predetermined width and length are mounted and installed on each guide rail 46 according to the size of the breeding room 10.

The guide rails 46 and 54 attached above and below extend to the front chamber 60 and the rear chamber 62, are bifurcated in the rear chamber 62, and are configured so that they can be mounted in parallel within the rear chamber 62. In this way, guide rail 4
6 and 54 are extended to the front chamber 60 and rear chamber 62 in order to facilitate the carrying in and out of the twin wall main body 14 into and out of the breeding room 10 and the disinfection of the twin wall main body itself.

When the twin wall main body 14 is made movable in this manner, as described above, when cleaning and disinfecting the inside of the breeding room, the twin wall main body 14 is carried out to the rear chamber 62 to clean and disinfect the inside. can be done easily. In addition, cleaning and disinfection of the twin wall main body 14 itself can be carried out in the rear chamber 62 or outside by removing the entire twin wall main body 14 from the guide rails 46, 54, so that the inside of the breeding room 10 is not contaminated by humans. Not at all.
Since the cleaned and disinfected twin wall body 14 is carried into the breeding room 10 from the front room 60, the twin wall body 14 can be easily replaced without anyone entering the breeding room 10. Therefore, the inside of the breeding room 10 can be kept in a highly clean state at all times. In FIG. 3, numerals 12A and 12B are doors for opening and closing.

If the guide rails 46 and 54 are connected in a loop as shown in FIG. 4, the side chamber 64 can be cleaned and cleaned.
Since it can be used as a disinfection room, the area of the cleaning and disinfection room becomes larger, which increases the cleaning and disinfection efficiency.
Easier to carry out.

FIG. 5 shows a case where this invention is applied to a breeding room 10 different from the one described above, and in this example, ventilation of a pair of left and right breeding room frames 64 is achieved by a pair of twin wall bodies 14 provided in the middle. is configured to do so. Since the rail extends into the rear chamber 62, the contaminated twin wall body 14 can be transported to the rear chamber 62 by opening the door 68.
After cleaning and other work, the clean twin wall main body 14 can be mounted on the rail and sent into the breeding room 10. In addition, although the twin wall bodies 14 are arranged side by side in FIG. 6, if the rails are extended to the rear chamber 62 as in the case of FIG. 5, the twin wall bodies 14 can be carried in and out from outside the breeding room. be able to.

The second embodiment shown in FIG. 7 is an example in which the movable means is provided on the lower side (floor side) of the twin wall main body, and a plurality of rollers 44 are attached to the lower end surface of the twin wall main body 14. , which is attached so as to be in rolling contact with the L-shaped floor guide rail 54. A single U-shaped guide rail 46 is attached to the ceiling 32 side to guide the upper end side surface of the twin wall main body 14.

With this configuration as well, the same effects as described above can be obtained.

[Effect of idea]

In the animal breeding room according to the present invention described above, a spare room is provided adjacent to the breeding room, a rail is provided from the breeding room to the spare room, and the twin wall main body is movably supported on the rail, so that The Twin Wall main body can be carried in and out freely. Therefore, the breeding room can be cleaned and disinfected without transporting the twin wall to the preliminary room and contaminating the breeding room, and the effect is that the filters and the twin wall itself can be replaced and cleaned outside the breeding room. has. As a result, the interior of the breeding room can be maintained at a high level of cleanliness at all times.
