本考案は実験動物飼育フード、更に詳細には放射性同位元素（RI）を利用した 薬物動態試験に用いられる放射線防護上の安全が配慮された実験動物飼育フード に関する。 This invention uses laboratory animal breeding food, more specifically, radioactive isotopes (RI). Laboratory animal breeding hood with consideration for radiation protection safety used in pharmacokinetic studies Regarding.

【従来の技術】[Conventional technology]

一般に薬物動態試験では、放射性同位元素（RI）で標識した被験薬物を投与す る前の動物及び被験薬を投与した後の動物を安全かつ正常に飼育しつつ尿、糞、 呼気を分析すると共に、従事する実験者に対しても放射線防護上の安全を保持す るために実験動物飼育フードが用いられている。 Generally, in pharmacokinetic studies, a test drug labeled with a radioisotope (RI) is administered. Animals before administration of the study drug and after administration of the study drug are kept in a safe and normal manner while urine, feces, In addition to analyzing exhaled breath, it also maintains radiological safety for the experimenters involved. Laboratory animal hoods are used to

【０００３】 然るところ、従来の実験動物飼育フードは、飼育ケースを単に格子棚等の空気 流通性棚で区画して上下に複数の区分飼育室を形成し、上部（天井部）からの吹 き出し空気を下部（床近傍側壁部）から排気する構成となっていた。0003 However, with conventional laboratory animal breeding hoods, the breeding case is simply placed on a lattice rack or other Separate them with circulation shelves to form multiple compartmented breeding rooms above and below, with air blowing from the top (ceiling). It was designed to exhaust air from the bottom (side wall near the floor).

【考案が解決しようとする課題】[Problem that the idea aims to solve]

而して、従来の実験動物飼育フードにおいて、上部から吹き出された空気は、 空気流通性棚を介して上部の区分飼育室から順次下位の区分飼育室を通過して排 気せられるものであった。 Therefore, in conventional laboratory animal breeding hoods, the air blown out from the top is The air is discharged from the upper divided breeding room through the lower compartmented breeding room through the air circulation shelf. It was something that bothered me.

【０００５】 すなわち、従来実験動物飼育フード内における空気の流れは、同じ空気が各区 分飼育室を通過する謂わば共通空気流方式であったため、上部区分飼育室内の細 菌等の下位の区分飼育室内への流入が避けられず、病気等の伝染の原因となり易 いと云う欠点があったと共に、空気流通性棚通過の際、動物及び実験者にとって 望ましくない空気の乱流が生じ易いと云う難点があった。[0005] In other words, the air flow in conventional laboratory animal hoods is such that the same air flows through each section. Because it was a so-called common airflow system that passed through the separate breeding rooms, the fine details in the upper separated breeding rooms were The inflow of bacteria, etc. into the lower-level breeding room is unavoidable and can easily cause the transmission of diseases, etc. In addition to having the disadvantage of being difficult to use, it is also dangerous for animals and experimenters when passing through an air circulation shelf. The disadvantage was that undesirable air turbulence was likely to occur.

【０００６】 そこで、本考案者は斯かる従来の問題を解決すべく種々検討を重ねた結果、各 区分飼育室毎に新鮮な空気が流入され、一の区分飼育室の空気が他の区分飼育室 に流入しないようにした本考案実験動物飼育フードを案出したものである。[0006] Therefore, as a result of various studies to solve the conventional problems, the inventor of the present invention has found various solutions. Fresh air is introduced into each compartment, and the air in one compartment is fed into the other compartments. We have devised the experimental animal breeding food of the present invention, which prevents the inflow of

【課題を解決するための手段】[Means to solve the problem]

すなわち、本考案は着脱自在の仕切板により上下に複数の区分飼育室及び一立 壁沿いに空気流路を形成した飼育ケースの上部に、送風機に連通する空気吹出口 を形設すると共に、当該各区分飼育室に吸引機に連通する空気吸込み口を形設し たことを特徴とする実験動物用飼育フードである。 In other words, the present invention has multiple divided breeding rooms above and below and a single stand using removable partition plates. At the top of the breeding case, which has an air flow path along the wall, there is an air outlet that communicates with the blower. At the same time, an air suction port that communicates with the suction machine is installed in each divided breeding room. This is a breeding food for laboratory animals that is characterized by:

【０００８】 本考案における仕切板は、空気非流通性のものであれば金属、合成樹脂等その 素材の如何を問わない。また、仕切板が複数使用せられる場合には、各仕切板の 大きさが同一のものであっても良いが、飼育ケースの一立壁沿いに形成せられる 空気流路において、該仕切板端部と飼育ケースの一立壁面との間隔が、上部仕切 板から下部仕切板に至り順次狭小となるような大きさの仕切板を用いるのが空気 流に良い結果を与える。[0008] The partition plate in this invention is made of metal, synthetic resin, etc. as long as it does not allow air to flow. It doesn't matter what the material is. In addition, when multiple partition plates are used, each partition plate They may be of the same size, but they are formed along one vertical wall of the breeding case. In the air flow path, the distance between the end of the partition plate and the vertical wall of the rearing case is the same as that of the upper partition. It is best to use partition plates with sizes that gradually become narrower from the board to the lower partition plate. Gives good results to flow.

【０００９】 空気流路が形成される具体的立壁部は、前面壁部、側面壁部等の如何を問わな いが、通常はガラス戸で構成される前面壁部とするのが好ましい。[0009] The specific standing wall where the air flow path is formed may be a front wall, a side wall, etc. However, it is usually preferable to have a front wall section consisting of a glass door.

【００１０】 空気吹出口の具体的形設部位は、飼育ケースの上部であれば、天井部、立壁上 部の如何を問わないが、空気流路の上方位たる天井上部とするのが有利である。 また、この空気吹出口には適宜風向調整羽根を付設し、吹き出し空気を各区分飼 育室に対応する空気流路形成立壁面に一旦当てて、当該各区分飼育室に反転流入 せしめるようにするのが特に良い結果を与える。0010 The specific location of the air outlet is the ceiling or a vertical wall if it is the upper part of the breeding case. Although it does not matter where it is placed, it is advantageous to place it above the ceiling above the air flow path. In addition, appropriate wind direction adjustment blades are attached to this air outlet to direct the blown air to each compartment. Once applied to the vertical wall that forms the air flow path corresponding to the breeding room, the air flows inverted into each compartmented breeding room. Particularly good results can be obtained by forcing it.

【００１１】 各区分飼育室に形設せられる空気吸込み口は、各別の排気管に連通するもので あっても良いが、一本の排気管にそれぞれ空気吸込口を連通したものであっても 良い。また、空気吸込口は空気流路と反対方向の立壁部、就中各仕切板上面近傍 立壁部に形設し、適宜エアーフィルターを装着せしめるのが特に望ましい。[0011] The air intake ports formed in each compartment are connected to separate exhaust pipes. Although it is okay to have one exhaust pipe connected to each air intake port, good. In addition, the air suction port should be placed on the vertical wall in the opposite direction to the air flow path, especially near the top surface of each partition plate. It is particularly desirable to form the filter on a vertical wall and attach an air filter as appropriate.

【作用】[Effect]

本考案は以上の如く構成せられているので、上部から吹き出された空気は、一 立壁沿いに形成された空気流路を上から下に移動する。その間各区分飼育室に設 けられた吸込口から空気が吸引排気されるので、空気流路中の空気が各別に各区 分飼育室に流入すると共に、仕切板の存在により各区分飼育室の空気が混合する ことはない。 Since the present invention is constructed as described above, the air blown out from the top is The air flow path formed along the vertical wall moves from top to bottom. During this time, the animals will be placed in each separate breeding room. Since air is sucked and exhausted from the closed suction port, the air in the air flow path is separated into each section. As the air flows into the separate breeding rooms, the air in each separated breeding room mixes due to the presence of partition plates. Never.

Together, an air flow path 4 is formed between the front end of the partition plate 2 and the front wall portion 11 of the rearing case 1. are doing. In addition, these partition plates 2 have four narrow air passages sequentially going from the upper stage to the lower stage. A partition plate 2 having a small dimension, or in other words, a partition plate 2 having a large depth dimension is used.

【００１６】 ５は送風機（図示せず）に連通する空気吹出口で、空気流路４の上方位天井部 12に形設せられている。また、この空気吹出口５には吹き出し空気を前面壁部11 に一旦当てて、各区分飼育室３に反転流入（図中破線矢印Ｐ）せしめる風向調整 羽根51が付設せられている。[0016] Reference numeral 5 denotes an air outlet communicating with a blower (not shown), which is located in the upper ceiling of the air flow path 4. It is shaped like 12. The air outlet 5 also has a front wall portion 11 for blowing air. Once applied to the air, adjust the wind direction to reverse the flow into each compartment breeding room 3 (dashed line arrow P in the figure). A feather 51 is attached.

【考案の効果】[Effect of the idea]

本考案によれば、上部から吹き出された空気は、各区分飼育室毎に独立した空 気流を形成して各吸込口から吸引排気されるため、各区分飼育室内の空気が混合 されることなく流れる結果、従来の如き空気伝染による病気の拡散を未然に防止 することができる。 According to this invention, the air blown out from the top is separated into separate air spaces for each compartment. The air in each compartment is mixed as it forms an air current and is sucked and exhausted from each suction port. As a result, the spread of diseases through airborne transmission is prevented. can do.

【００２０】 しかも、本考案における仕切板は何ら空気流通性が存しないため、従来の格子 棚の如き空気乱流が生じにくいため、動物や実験者に悪影響を与えることはない 。[0020] Moreover, since the partition plate in this invention has no air circulation, it is difficult to use the conventional grid. Since air turbulence is less likely to occur like on a shelf, there is no negative impact on animals or experimenters. .
