Abstract
Description
<クリーンルーム施設の構成>
図1は、第1実施形態に係るクリーンルーム施設100の各部屋の間取りを示す説明図である。
なお、図1では、所定のドア(例えば、ドアD1)が開かれた場合に空気が流れる向きを白抜きの破線矢印で示している。クリーンルーム施設100は、前処理室R2や調製室R3といった複数のクリーンルームの温度や室圧、清浄度等を調整する施設であり、例えば、細胞の培養加工や無菌製剤(ワクチン、注射剤、点眼剤等)の製造に用いられる。図1に示すクリーンルーム施設100には、クリーンルームとして、更衣室R1と、前処理室R2と、調製室R3と、着衣室R4と、脱衣室R5と、3つの部屋R6,R7,R8と、が設けられている。
なお、図2では、調製室R3や3つの部屋R6,R7,R8を示し、前処理室R2(図1参照)等の図示を適宜に省略している。また、図2では、空気の流れを実線矢印で示している。図2は、例えば、調製室R3からダクトシャフトDS1を介して、チャンバC3に空気が導かれるといったように、空気の流れに着目した模式的な断面図になっている。図2では、安全キャビネット32(図1参照)やインキュベータ41~43(図1参照)の図示を省略している。
クリーンルーム施設100(図2参照)は、部屋R6(図2参照)に対応する構成として、前記したファンフィルタユニット14,15や圧力センサ22の他に、制御装置80を備えている。制御装置80は、給気ファン14aや還気ファン15aを制御する装置である。制御装置80は、図示はしないが、CPU(Central Processing Unit)、ROM(Read Only Memory)、RAM(Random Access Memory)、各種インタフェース等の電子回路を含んで構成されている。そして、ROMに記憶されたプログラムを読み出してRAMに展開し、CPUが各種処理を実行するようになっている。
図10は、比較例に係るクリーンルーム施設100Fの各部屋の間取りを示す説明図である。
図10の比較例では、調製室R3に3台のインキュベータ41~43が設けられているが、これらのインキュベータ41~43を収容する部屋R6,R7,R8(図1参照)が設けられていない。なお、インキュベータ41~43で作業員が細胞等を出し入れする過程で、機材や床面にエアロゾルが付着する(試料汚染が生じる)可能性があるため、一つの調製室R3に複数の患者の細胞等が混在している状態で処理が行われケースは少なかった。つまり、これまでのクリーンルーム施設100Fでは、作業員が調製室R3で1人の患者の細胞等を処理した後、調製室R3を滅菌(又はアルコールで清拭)した上で、別の患者の細胞等を扱うようにしていた。
クリーンルーム施設100の通常使用時には、図2に示す空調機9やファンフィルタユニット11~19が所定に駆動される。第1ダンパ56aは、この第1ダンパ56aに対応する部屋R6の通常使用時には開状態であり、チャンバC3と部屋用チャンバC6との間を連通させる。これによって、チャンバC3から第1ダンパ56a及び部屋用チャンバC6を順次に介して、清浄な空気が部屋R6に供給される。
例えば、作業員が部屋R8で作業しているときに試料をこぼすといったことがある。また、ある患者の細胞等が試料として処理された後、別の患者の細胞等が処理される際(いわゆるチェンジオーバーの際)にも滅菌が行われることが多い。
例えば、部屋R8の滅菌時には、所定の滅菌ガス(過酸化水素ガス等)を噴射する除染装置81が部屋R8に載置される。そして、部屋R8のドア8b(図1参照)が閉められた状態で、除染装置81の運転スイッチ(図示せず)が押されると、除染装置81から滅菌ガスが噴射され、部屋R8に滅菌ガスが充填される。このように、複数の部屋R6,R7,R8のうち少なくとも一つの部屋(例えば、部屋R8)の滅菌が行われる際には、当該部屋に所定の滅菌ガスが充填される。
図5に示す除染装置82は、滅菌対象の部屋R8に所定の滅菌ガス(過酸化水素ガス等)を充填した後、この滅菌ガスを無害化する所定の触媒ガス(例えば、白金やパラジウムを含む触媒)を充填する装置である。除染装置82には、給気側ホース82aが接続されるとともに、排気側ホース82bが接続される。給気側ホース82aは、除染装置82から部屋R8に所定の滅菌ガスや触媒ガスを導く管である。排気側ホース82bは、部屋R8から除染装置82に排気ガスを導く管である。
また、滅菌ガスを無害化する所定の触媒フィルタ(図示せず)を除染装置82の中に組み込むようにしてもよい。また、触媒フィルタ(図示せず)を備える分解装置(図示せず)を別途設けてもよい。
第1実施形態によれば、インキュベータ41~43(図1参照)を配置する部屋R6,R7,R8を個別に設けることで、調製室R3の他、3つの部屋R6,R7,R8で作業を並行して行うことが可能になる。これによって、試料を扱う際の作業効率が高められる。また、作業員が所定の試料を部屋R8で処理した後、この部屋R8を滅菌する際、調製室R3や他の部屋R6,R7の滅菌を行う必要が特にない。したがって、滅菌に要する時間やコストを削減できる。
第2実施形態は、部屋R6にシャッタ6e(図6参照)が設けられる他、部屋R7,R8にシャッタ7e,8e(図6参照)が設けられる点が、第1実施形態とは異なっている。また、第2実施形態は、試料の移動に搬送機械90(図6参照)が用いられる点が、第1実施形態とは異なっている。なお、その他については、第1実施形態と同様である。したがって、第1実施形態とは異なる部分について説明し、重複する部分については説明を省略する。
なお、図6の搬送機械90の付近の矢印は、試料の容器N1(図7参照)が移動する方向を示している。図6に示すクリーンルーム施設100Aの部屋R6には、開閉可能なシャッタ6eが設けられている。このシャッタ6eは、試料の移動に用いられる開閉可能な窓であり、部屋R6の仕切6aに設けられている。同様に、他の部屋R7,R8にもシャッタ7e,8eが設けられている。例えば、搬送機械90とインキュベータ41との間で試料の容器N1(図7参照)の受け渡しが行われる際には、部屋R6のシャッタ6eが自動で開くようになっている。
以下の説明では、一例として、安全キャビネット32からインキュベータ41に試料の容器N1が搬送される場合について説明する。なお、インキュベータ41~43のいずれかから安全キャビネット32に培養済みの容器N1を移動させることも可能である。
第2実施形態によれば、試料の容器N1の移動に搬送機械90が用いられることで、容器N1を移動させる際の手間や時間を削減できる。また、調製室R3等で作業を行う人の人数が少なくてすむため、試料を床にこぼすといった試料汚染が生じにくくなる。その結果、調製室R3や部屋R6~R8の滅菌の頻度が少なくなるため、低コスト化を図ることができる。
以上、本発明に係るクリーンルーム施設100,100Aについて各実施形態で説明したが、本発明はこれらの記載に限定されるものではなく、種々の変更を行うことができる。例えば、各実施形態では、部屋R6(図2参照)からダクトシャフトDS6を介して、調製室R3に空気が導かれる構成について説明したが、これに限らず、例えば、図8や図9の各変形例のようにしてもよい。
図8に示すクリーンルーム施設100Bは、例えば、部屋R6に対応する構成として、部屋用チャンバC6と、ファンフィルタユニット14,76と、ダクトシャフトDS6と、第1ダンパ56aと、を備えている。部屋用チャンバC6は、部屋R6の天井裏の空間である。この部屋用チャンバC6は、隣り合う部屋用チャンバC7との間が壁部材(図示せず)で仕切られるとともに、調製室R3との間が隔壁54で仕切られている。部屋用チャンバC6の隔壁54には、第1ダンパ56aが設けられている。なお、部屋R6の通常使用時には、第1ダンパ56aは開状態になっている。
ファンフィルタユニット14の給気ファン14aは、部屋R6への給気を行う送風機であり、部屋用チャンバC6に設けられている。別のファンフィルタユニット76の還気ファン76a(第1還気ファン)は、部屋R6から流出する空気の少なくとも一部を、ダクトシャフトDS6を介して、部屋用チャンバC6に戻す機能を有している。すなわち、還気ファン76a(第1還気ファン)は、部屋R6から所定の隙間79aを介して流出する空気の一部をダクトシャフトDS6に導き、残りの空気を排気する機能を有している。ダクトシャフトDS6の下流端には、多孔板74(又はグレーチング)が設けられていてもよい。なお、他の部屋R7,R8に対応する構成についても同様である。
要するに、図8に示す第1の変形例は、例えば、部屋R6の空気の一部がダクトシャフトDS6を介して部屋用チャンバC6に戻される点が、第1実施形態(図2参照)とは異なっている。このような構成によれば、部屋R6から調製室R3への空気の移動がほとんどないため、部屋R6で試料汚染が生じた直後に、エアロゾルが調製室R3に流入することを確実に防止できる。
図9に示す第2の変形例は、前記した第1の変形例(図8参照)にファンフィルタユニット86,87,88を追加した構成になっている。例えば、部屋R6に対応するファンフィルタユニット86は、還気ファン86a(第2還気ファン)と、フィルタ86bと、を備えている。還気ファン86aは、部屋R6から流出する空気の少なくとも一部を、ダクトシャフトDS6を介して、部屋用チャンバC6に戻す機能を有している。すなわち、還気ファン86a(第2還気ファン)は、部屋R6から流出する空気を自身(つまり、還気ファン86a)を介して、ダクトシャフトDS6に導く送風機である。なお、他の部屋R7,R8に対応する構成についても同様である。このような構成によれば、例えば、還気ファン76a,86aが共に駆動することで、部屋R6からダクトシャフトDS6を介して通流する空気の流量を適切に調整できる。
また、各実施形態では、調製室R3の室圧と、部屋R6,R7,R8の室圧と、が異なる場合について説明したが、これに限らない。すなわち、調製室R3の室圧と、部屋R6,R7,R8の室圧と、が等しくなるようにしてもよい。
また、各実施形態では、チャンバC3や部屋用チャンバC6,C7,C8にダクトが特に設けられない構成について説明したが、これに限らない。すなわち、ダクトK1,K2(図2参照)を介して供給される空気を給気側の各ファンフィルタユニットに導くダクト(図示せず)が別途設けられてもよい。
また、クリーンルーム施設100の建設時に部屋R6,R7,R8が設けられていてもよいが、これらの部屋R6,R7,R8が後付けで設置されてもよい。この場合において、調製室R3には、部屋に繋がっていない窓や扉付きの仕切(図示せず)が予め設けられ、前記した部屋を調製室R3に後から追加可能とする構成であってもよい。
また、前記した機構や構成は説明上必要と考えられるものを示しており、製品上必ずしも全ての機構や構成を示しているとは限らない。
