【発明の属する技術分野】
本発明は、細胞培養を行う培養容器への培養液の交換作業を行うための培養液交換器に関する。
【0002】
【従来の技術】
従来から、細胞培養を培養容器内で行っている。また、培養容器についての出願も行われている(例えば、特許文献1及び特許文献2参照。)。しかし、この培養容器の培養液の交換作業は、培養容器及びピペット等の器具を手に持ってピペットの先端を培養容器の開口部に挿入することにより、手作業によって行っていた。この交換作業は、コンタミネーションを防止するために培養容器の開口部に液が付着しないように行う必要がある等の理由から、清潔な環境下で慎重に行う必要があり、熟練と集中力を必要とする作業であった。また、多量の培養容器の交換作業は時間がかかり、重労働な作業であった。このため、交換作業の効率化を図る必要があった。
【0003】
一方、この交換作業を機械的に行う装置も案出されている(例えば、特許文献3、特許文献4及び特許文献5参照。)。しかし、このような装置は規模が大きくなってコストが大きくなることから、導入し難いのが現状であった。

【発明が解決しようとする課題】
そこで、本発明者は、このような課題の原因を究明してこのような課題を解決するべく、鋭意研究を重ねた結果、本発明に至ったのである。
【0006】
すなわち、本発明は、培養液の交換作業の効率化を図れるとともにコンパクトに構成できる培養液交換器を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明の培養液交換器は、培養液の注入又は排出を行う開口部を有する培養容器が定置される容器定置手段と、注入パイプ及び排出パイプの先端側と該培養容器の開口部側とが対向するように該注入パイプ及び排出パイプが支持されるパイプ支持手段とを備え、該パイプ支持手段は、該支持された注入パイプ及び排出パイプがスライドして該開口部から該培養容器内へ挿入又は抜出させられるスライド手段を有することを特徴とする。特には、前記容器定置手段は、前記定置された培養容器の角度が調節され、該容器定置手段を傾斜させる機構から成る容器角度調節手段を有し、前記パイプ支持手段は、前記支持された注入パイプ及び排出パイプの角度が調節され、該パイプ支持手段を傾斜させる機構から成るパイプ角度調節手段を有し、前記パイプ支持手段は前記容器定置手段よりも高い位置に設置されることを特徴とする。
【0008】
また、本発明の培養液交換器は、前記培養液交換器において、前記容器定置手段は、前記定置された培養容器の角度が調節される容器角度調節手段を有し、前記パイプ支持手段は、前記支持された注入パイプ及び排出パイプの角度が調節されるパイプ角度調節手段を有することを特徴とする。
【0009】
また、本発明の培養液交換器は、前記培養液交換器において、前記パイプ支持手段は、前記注入パイプ及び排出パイプがパイプホルダを介して支持板に支持される構成であり、該パイプホルダが該支持板に対して着脱可能であることを特徴とする。
【0010】
【発明の実施の形態】
次に、本発明に係る培養液交換器の実施の形態について、図面に基づいて詳しく説明する。
【0011】
図1において、符号10は、本発明の培養液交換器である。この培養液交換器10は、基台11上に、培養液の注入又は排出を行う開口部12を有する培養容器14が定置される容器定置手段16と、注入パイプ18及び排出パイプ20の先端側と培養容器14の開口部12側とが対向するように注入パイプ18及び排出パイプ20が支持されるパイプ支持手段22とを備えて構成されている。パイプ支持手段22は、支持された注入パイプ18及び排出パイプ20がその先端側へスライドして培養容器14の開口部12から培養容器14内へ挿入させられるスライド手段24を有している。なお、基台11を支持する支持脚13は基台に螺入されており、支持脚13を回動させることにより、基台11自体の水平方向に対する角度を調節できる。
【0012】
容器定置手段16は、培養容器14が定置される定置板36を備えている。この定置板36は、図6に示すように、摘子38と一体的に構成された螺子39が螺入されたスライド壁40を備え、摘子38を回動させることによりスライド壁40を幅方向(y軸方向)にスライドさせてスライド壁40によって培養容器14を挟持することにより、培養容器14の幅に対応して培養容器14を位置決めできるように構成されている。
【0013】
また、容器定置手段16は、図1に示すように、定置された培養容器14の角度θ1 が調節される容器角度調節手段26を有している。この容器角度調節手段26は、基台11に固定された固定部材28と、固定部材28に対して回動可能な摘子30と、摘子30と一体的に構成された図示しない螺子が螺入されたスライド部材32と、スライド部材32及び定置板36にピン結合されたリンク34とを備え、摘子30を回動させてスライド部材32をスライドさせることによりリンク34を回動移動させて、定置板36を上下方向(xz平面方向)で且つピン37のまわりに回動させるように構成されている。すなわち、容器角度調節手段26は、基台11及び固定部材28から成る固定節、スライド可能なスライド部材32、回動可能なリンク34、及び回動可能な定置板36の4個の節から構成される1自由度の4節連鎖機構であるため、スライド部材32のスライド運動によって全ての部材の運動を最もコンパクトな構成によって制御できる。なお、本明細書においてピン結合とは、部材同志が回動可能な1自由度の連結を意味する。また、1自由度の連鎖機構とは、1個の節を運動させることにより他の節の運動を制御できる1自由度の限定連鎖を意味する。
【0014】
パイプ支持手段22は、図1に示すように、注入パイプ18及び排出パイプ20が支持される支持板42と、基台11に固定されるとともに支持板42にピン結合された垂設部材44と、基台11に固定された固定部材46と、固定部材46に対して回動可能な摘子48と、摘子48と一体的に構成された螺子49が螺入されたスライド部材50と、スライド部材50及び支持板42にピン結合されたリンク52とを備え、摘子48を回動させてスライド部材50をスライドさせることによりリンク52を回動移動させて、支持板42を上下方向(xz平面方向)で且つピン54のまわりに回動させるように構成されている。これら固定部材46、摘子48、スライド部材50、及びリンク52によって、支持された培養液パイプ18及び20の角度θ2 を調節するパイプ角度調節手段56が構成される。すなわち、パイプ角度調節手段56は、基台11及び固定部材46から成る固定節、スライド可能なスライド部材50、回動可能なリンク52、及び回動可能な支持板42の4個の節から構成される4節連鎖機構であるため、スライド部材50のスライド運動によって全ての部材の運動を最もコンパクトな構成によって制御できる。なお、支持板42には、培養容器14側と注入パイプ18及び排出パイプ20側とに仕切る仕切板70が設けられている。
【0015】
ここで、容器定置手段16の機構において、培養容器14内の培養液が開口部12から外へ漏れないように培養容器14を傾斜させるためには、θ1 >0°である必要がある。一方で、θ1 が大きすぎると、注入パイプ18及び排出パイプ20をパイプ支持手段22によって高い位置で支持する必要が生じ、装置全体が大掛かりなものとなるため、θ1 <45°程度が好ましい。また、図7(a)に示すようにリンク34の角度をθ10とすると、容器角度調節手段26が定置板36の下部に収まる程度にコンパクトに構成するには、0°<θ10<90°であることが好ましい。なお、θ10<90°ならば、図7(b)に示すように、スライド部材32を速度V11でスライドさせた場合のリンク34の速度の瞬間中心O34は定置板36上に位置する。次に、パイプ支持手段22の機構においても、容器定置手段16の機構と同様に、θ2 >0°である必要があり、θ2 <45°程度が好ましい。また、リンク52の角度をθ20とすると、容器定置手段16の機構と同様に、0°<θ20<90°であることが好ましい。また、リンク52の速度の瞬間中心は、支持板42上に位置する。
【0016】
なお、容器定置手段16の機構において、通常の螺子構造は時計まわりに回動させることにより螺入されていく構造であることを考慮すると、摘子30を時計まわりに回動させれば、スライド部材32は図7(a)の右方向(V11の方向)へスライドする。一方、図7(b)に示すように、スライド部材32がV11の方向にスライドすれば、定置板36の上端はV13の方向に回転する。なお、図7において、V12はリンク34の上端の回転速度である。これにより、摘子30を時計まわりに回動させれば、スライド部材32が図7(a)のV11の方向にスライドして、定置板36の上端は図7(a)のV13の方向に上昇する。よって、摘子30を時計まわりに回動させれば、定置板36の上端は上昇し、摘子30を反時計まわりに回動させれば、定置板36の上端は下降することとなる。一方、パイプ支持手段22の機構においては、摘子48を反時計まわりに回動させれば支持板42の上端は上昇し、摘子48を時計まわりに回動させれば支持板42の上端は下降することとなる。このため、例えば、正面側から右手で摘子48を摘み、左手で摘子30を摘んだ場合には、摘子48及び30を正面側から見て前転させれば定置板36の上端及び支持板42の上端は下降し、摘子48及び30を正面側から見て後転させれば、定置板36の上端及び支持板42の上端は上昇することとなる。よって、作業者は、定置板36及び支持板42の両者共に、正面側から見て前転させれば傾斜角度を小さくでき、後転させれば傾斜角度を大きくできるとの認識を持って、定置板36及び支持板42の傾斜角度の調節を行うことができる。また、摘子30が基台11の一端側に位置し、摘子48が基台11の他端側に位置するため、摘子30又は48を手で摘んで回動させることが容易である。
【0017】
スライド手段24は、注入パイプ18及び排出パイプ20を保持するパイプホルダ58、パイプホルダ58が着脱可能に固定されるスライド部材62、及び、凹部66に係合され得る爪部材68を備えている。爪部材68は、支持板42の長手方向に延びるように支持板42の側面に設けられた図1に示す溝64に沿って、スライドする。爪部材68に固定されたスライド部材62は、支持板42の長手方向に延びるように支持板42の上面に設けられた図3に示す溝60に沿って、爪部材68とともにスライドする。長手爪部材68を凹部66に係合しておくことにより、爪部材68と共にスライド可能な注入パイプ18及び排出パイプ20がスライドしないように固定できる。
【0018】
次に、本発明の培養液交換器10の作用について、以下に説明する。
【0019】
まず、図1に示すように、注入パイプ18及び排出パイプ20をパイプホルダ58を介してスライド部材62に取り付けておき、注入パイプ18は注入用ポンプに、排出パイプ20は排出用ポンプに接続しておく。なお、培養容器14から培養液を排出しやすいように、排出パイプ20を注入パイプ18よりも下側で、排出パイプ20の先端が注入パイプ18よりも突出するように支持するのが好ましい。次に、培養容器14を定置板36上に載置し、摘子38を回動させてスライド壁40を培養容器14の幅方向にスライドさせ、スライド壁40を培養容器14に密着させながらスライド壁40によって培養容器14を挟持して、培養容器14の位置決めを行う。
【0020】
このようにして培養容器14の位置決め作業が終了すると、爪部材68を持ち上げて凹部66から解除し、溝64に沿って斜め下へスライドさせる。爪部材68が斜め下へスライドさせられることにより、爪部材68に固定されたスライド部材62が支持板42上の溝60に沿って斜め下へスライドし、図4に示すように、注入パイプ18及び排出パイプ20の先端が仕切板70を貫通して培養容器14の開口部12へ挿入される。注入パイプ18及び排出パイプ20は支持板42に対して平行にスライドするため、注入パイプ18及び排出パイプ20の先端が開口部12の周囲に接触することなくスムーズに挿入される。
【0021】
注入パイプ18及び排出パイプ20が開口部12へ挿入された状態で、排出用ポンプを作動させ、培養容器14から排出液パイプ20を介して培養液を排出する。次に、注入用ポンプを作動させ、培養容器14から注入液パイプ18を介して新たな培養液が注入される。新たな培養液の注入が終了すると、爪部材68を斜め上へスライドさせることにより、注入パイプ18及び排出パイプ20が開口部12から抜出され、培養液の交換作業が終了する。
【0022】
ここで、培養容器14の形状、開口部12の位置、又は培養容器14内の培養液の量等に対応して培養容器14の角度θ1 を調節する必要のある場合は、摘子30を回動させて調節する。また、開口部12と注入パイプ18及び排出パイプ20との位置関係等に対応して注入パイプ18及び排出パイプ20の挿入角度を調節する必要のある場合は、摘子48を回動させて角度θ2 を調節する。爪部材68を溝64に沿って斜め下へスライドさせる。注入パイプ18及び排出パイプ20の先端が開口部12の周囲に接触することなくスムーズに挿入されるためには、例えば図1に示すように、開口部12の中心付近が注入パイプ18及び排出パイプ20の延長線A上に略位置するように角度θ1 及び角度θ2 を調節することが好ましい。また、培養液の排出作業後に培養容器14の底に培養液が残らないように、排出パイプ20の傾斜角度である角度θ2 を調節して排出パイプ20の先端を培養容器14の底面に位置させることが好ましい。
【0023】
また、パイプホルダ58はスライド部材62に設けた図3に示す穴63に嵌合されてスライド部材62に螺子留めされているため、注入パイプ18及び排出パイプ20を滅菌処理する必要のある場合は、図5に示すように、注入パイプ18及び排出パイプ20が保持されたパイプホルダ58をスライド部材62から取り外し、注入パイプ18及び排出パイプ20を滅菌処理することができる。この場合、パイプホルダ58を保持して取り外すことができるため、安全上好ましい。
【0024】
以上、本発明の一実施形態について説明したが、本発明の培養液交換器は、その他の形態でも実施し得るものである。
【0025】
例えば、培養液交換器10において、図8に示すように、パイプ支持手段22を基台11に対して水平方向(xy平面方向)へ回動可能なターンテーブル80上に設けても良い。この場合、注入パイプ18及び排出パイプ20を水平方向に回動させて、注入パイプ18及び排出パイプ20の開口部12への水平方向における挿入角度を調節できる。
【0026】
また、培養液交換器10において、図9に示すように、爪部材68の移動長さを読み取るための目盛り82、定置板36の傾斜角度を読み取るための目盛り84、及び支持板42の傾斜角度を読み取るための目盛り86を備えても良い。この場合、爪部材68の移動長さを読み取ることにより、注入パイプ18及び排出パイプ20の開口部12へ挿入した長さを客観的に把握できる。また、異なる形状の培養容器14毎に、定置板36及び支持板42の傾斜角度を記録しておくことにより、培養容器14に最適な傾斜角度を瞬時に設定できる。
【0027】
また、培養液交換器10において、図10に示すように、注入パイプ18及び排出パイプ20をスライド方向へ微動させることのできる微動調節手段90を備えても良い。この微動調節手段90は、スライド手段24によってスライド部材62とともにスライドする摺動台92と、摺動台92に螺入されるとともにスライド部材62に連結された螺子94とを備え、螺子94を回動させることによりスライド部材62を摺動台92に沿って摺動させることができる。この場合、スライド手段24によって排出パイプ20の先端を培養容器14の底付近まで移動させた後、螺子94を回動させて排出パイプ20の先端を培養容器14の底面まで微動させることができる。これにより、注入パイプ18及び排出パイプ20を培養容器14内へ挿入した時に排出パイプ20の先端が培養容器14の底面に衝撃を加えることがなく、排出パイプ20の先端付近又は培養容器14の破損を防止できる。
【0028】
以上、本発明の実施形態について図面に基づいて説明したが、本発明は図示したものには限定されない。例えば、容器定置手段はスライド壁36によって培養容器12を挟持するものには限定されず、培養容器12の位置決めを行えるものであれば良い。例えば、培養容器を帯状金具又はベルト等によって固定するものであっても良い。また、容器角度調節手段及びパイプ角度調節手段は、4節連鎖機構に限定されず、1自由度の限定連鎖機構であれば良い。また、培養液交換器10の角度θ1 及び角度θ2 の調節作業において、パイプホルダ58等に注入パイプ18及び排出パイプ20と平行な視準線を有する視準器を設けておき、注入パイプ18及び排出パイプ20の後端側から目視して視準線が開口部12の略中央部に一致するように角度θ1 及び角度θ2 を調節しても良い。また、本発明は培養容器が定置された容器定置手段を固定しておいて注入パイプ及び排出パイプをスライドさせる構成には限定されず、注入パイプ及び排出パイプを固定しておいて培養容器をスライドさせることによって注入パイプ及び排出パイプを培養容器内へ挿入又は抜出させる構成であっても良い。
【0029】
その他、本発明の技術的範囲には、その趣旨を逸脱しない範囲で当業者の知識に基づき種々なる改良,修正,変形を加えた態様も含まれる。また、同一の作用又は効果が生じる範囲内で、いずれかの発明特定事項を他の技術に置換した形態で実施しても良い。
【0030】
【発明の効果】
本発明の培養液交換器によれば、スライド手段によって注入パイプ及び排出パイプをスライドさせて培養容器の開口部へ挿入して培養液の交換作業を行うことができる。このため、手でピペットを保持して培養容器の開口部周辺に液が付着しないように慎重に交換作業を行うのと異なり、効率良く交換作業を行うことができる。また、容器定置手段、パイプ支持手段及びスライド手段から構成されるため、コンパクトに構成できる。
【0031】
また、容器角度調節手段とパイプ角度調節手段とを備えた本発明の培養液交換器によれば、培養容器の形状等に応じて培養容器及び培養液パイプの角度を適宜変更することができる。また、容器角度調節手段とパイプ角度調節手段とにより、培養容器と注入パイプ及び排出パイプとの角度を別個独立に変更することができる。このため、培養容器の形状によって培養容器の方向と注入パイプ及び排出パイプの挿入方向とを異ならせる必要がある場合等に対応して、培養容器と注入パイプ及び排出パイプとの角度を適宜変更することができる。
【0032】
また、パイプホルダが着脱可能である本発明の培養液交換器によれば、培養液パイプに触れずに注入パイプ及び排出パイプを取り外して滅菌処理を行うことができる。

[0002]
[Prior art]
Conventionally, cell culture is performed in a culture vessel. Applications for culture vessels have also been filed (see, for example, Patent Document 1 and Patent Document 2). However, the operation of exchanging the culture solution in the culture container has been performed manually by holding the culture container and an instrument such as a pipette in hand and inserting the tip of the pipette into the opening of the culture container. This replacement work must be performed carefully in a clean environment because it is necessary to prevent the liquid from adhering to the opening of the culture vessel in order to prevent contamination. It was necessary work. In addition, replacement of a large number of culture vessels took time and was a laborious operation. For this reason, it was necessary to improve the efficiency of the replacement work.
[0003]
On the other hand, devices that perform this replacement work mechanically have also been devised (see, for example, Patent Document 3, Patent Document 4, and Patent Document 5). However, since such a device is large in scale and high in cost, it is difficult to introduce such a device at present.

[0016]
In consideration of the fact that the normal screw structure is a structure that is screwed in by rotating clockwise in the mechanism of the container placing means 16, if the knob 30 is rotated clockwise, the slide The member 32 slides in the right direction (direction of V11) in FIG. On the other hand, as shown in FIG. 7B, when the slide member 32 slides in the direction of V11, the upper end of the stationary plate 36 rotates in the direction of V13. In FIG. 7, V12 is the rotational speed of the upper end of the link 34. Thus, if the knob 30 is rotated clockwise, the slide member 32 slides in the direction of V11 in FIG. 7A, and the upper end of the stationary plate 36 is in the direction of V13 in FIG. 7A. To rise. Therefore, if the knob 30 is rotated clockwise, the upper end of the stationary plate 36 is raised, and if the knob 30 is rotated counterclockwise, the upper end of the stationary plate 36 is lowered. On the other hand, in the mechanism of the pipe support means 22, the upper end of the support plate 42 rises when the knob 48 is rotated counterclockwise, and the upper end of the support plate 42 when the knob 48 is rotated clockwise.
