Abstract
Description
また、対象者からは、血液の他に尿等の液性成分を採取する場合があるが、この場合においても、対象者の採取位置と液性成分を採取する採取容器の設置位置との間に十分な落差を設けることは困難な場合があった。
先ず、本発明の液性成分採取装置の好ましい一実施形態に係る血液採取装置100の第1実施形態について、図1~図3を参照しながら説明する。
図1は、血液採取装置100により血液を採取している状態を示す図である。図2は、図1の部分拡大図である。図3は、血液採取装置100に好適に用いられる圧力調整補助具200を示す図である。
血液貯留容器21の側面は、血液貯留容器21内に貯留される血液を視認可能とする観点から透明性を有する材料から構成することが好ましい。可撓性を有する材料としては、ポリ塩化ビニル、ポリエチレン、ポリプロピレン、ポリウレタン、シリコーン、エチレン酢酸ビニル共重合樹脂、合成ゴム、各種エラストマー等の軟質合成樹脂を用いることができる。血液貯留容器21の一端である上端は開口となっており、第1キャップ23に嵌合されて密閉されている。血液貯留容器21の他端である下端部にはボトムキャップ210が嵌合されており、接着剤により接合されている。
第1接続部24は、その外径が第1収容容器22の開口における内径と略同一であり、第1接続部24の外周面に第1収容容器22の開口近傍が被嵌可能となされている。第2接続部25は、その外径が血液貯留容器21の開口の内径と略同一であり、第2接続部25の外周面に血液貯留容器21の開口近傍が被嵌可能となされている。
第1接続部24の外周面と第1収容容器22の開口近傍における内周面との間には、圧力調整空間26の密閉性を向上させるための密閉部材(図示せず)が介在配置されている。これにより、圧力調整空間26のより確実な密閉構造を確保できる。
密閉部材としては、例えば、シリコンゴムから構成される環状の部材を用いることができる。尚、密閉部材は、第1接続部24の外周面に被冠できる構成であればよく、素材としては、上記シリコンゴムに限られず、各種ゴム、各種エラストマー等の弾性部材を用いることができる。
また、密閉部材は、第2接続部25の外周面と血液貯留容器21の開口近傍における内周面との間に配置してもよい。
尚、第1キャップ23の下面における血液貯留容器21の内部空間に面する部分の形状は、図2に示すように、上方向に向かって漸次縮径してなる形状であるのが好ましい。更には、その頂部に貫通孔である第1連通路28が設けられてなる構成が好ましい。上記構成であれば、血液貯留容器21内に貯留された血液が誤って第1連通路28から流出することを防止できる。
第1連通路28と通気管42とは、第1キャップ23における第1連通路28が形成されている部分の上面側に設けられた第2突起部232に通気管42の端部を係合させることにより接続されている。
そして、注入手段により第2連通路29から流体を注入することにより、圧力調整空間26が加圧される。この際、圧力調整空間26の外側を形成している第1収容容器22は可撓性を有さないため、可撓性を有する血液貯留容器21が圧力調整空間26の加圧の影響を受けてつぶれるように変形される。また、圧力調整空間26が加圧されることによってつぶれるように変形した血液貯留容器21は、加圧された圧力調整空間26を減圧することによって、元の形状に復元する。このように、圧力調整空間26の加圧や減圧によって血液貯留容器21を変形させることにより、採血を無菌的かつ容易に行うことができる。
第1の手順では、まず、第2連通路29から圧力調整空間26に空気を注入し、圧力調整空間26を加圧しておく。これにより、血液貯留容器21は、つぶれるように変形する。
この状態で、採血針80を対象者(患者)に刺す。次に、第1連通路28に接続された通気管42から血液貯留容器21の内部空間の空気を吸引すると共に、第2連通路29に接続された流体注入チューブ291から圧力調整空間26の空気を吸引する。すると、血液貯留容器21の内部空間の空気が吸引されること、及び圧力調整空間26の加圧状態が解除されて血液貯留容器21が元の形状に復元することにより、血液貯留容器21内に陰圧が負荷される。これにより、採血針80から採取された血液は、血液貯留容器21側に強く吸引されて血液貯留容器21に導入される。
この状態で、採血針80を対象者(患者)に刺した後、採血チューブ5の経路を開放する。すると、血液貯留容器21の内部空間の陰圧により採血針80から採取された血液は、血液貯留容器21側に強く吸引されて血液貯留容器21に導入される。
第1の接続部430は、硬質の合成樹脂により構成され、第1空気流通路410の先端側に連結される。この第1の接続部430には、シリンジ(図示せず)等の空気吸引装置が接続される。
以上の圧力調整補助具400によれば、一対の第2の接続部440を、通気管42及び流体注入チューブ491に接続した状態で、第1の接続部430に空気吸引装置を接続して、この空気吸引装置により空気を吸引することで、通気管42及び流体注入チューブ291を介して、血液貯留容器21の内部空間の空気及び圧力調整空間26の空気を同時に吸引して、血液貯留容器21の内部空間及び圧力調整空間26の両方を同時に同程度減圧できる。
血液採取装置100を、可撓性を有する血液貯留容器21と、この血液貯留容器21を収容する硬質合成樹脂製の第1収容容器22と、血液貯留容器21と第1収容容器22との間に形成された圧力調整空間26と、を含んで構成した。これにより、圧力調整空間26を加圧したり減圧したりすることによって、採血を無菌的かつ容易に行うことができる。よって、対象者の血圧や対象者の採血位置と血液採取装置の設置位置との落差圧に依存することなく、簡易に血液の採取を行える。
尚、第2実施形態以降の説明にあたって、同一構成要件については同一符号を付し、その説明を省略もしくは簡略化する。
血液貯留容器21Aに収容された血液成分は、第1液性成分採取口214を注射針等の穿刺具にて破断穿刺することにより、採取することができる。この際に、第1液性成分採取口214の形成された領域には中空の円筒部215が形成されているため、穿刺具を確実に第1液性成分採取口214に穿刺することができる。
更に、第1液性成分採取口214の位置と、第1収容容器22の内面底部の位置との間の距離が、前記穿刺具が収容可能な距離に設定されているのが好ましい。上記構成であれば、穿刺具を第1液性成分採取口214に穿刺した状態で、第1収容容器22内部に収容させることができる。穿刺具に適宜連通可能な開閉機構を有していれば、血液貯留容器21A内の血液成分を所望に応じて採取・保存が可能になる。
血液貯留容器21Aの下端に第1液性成分採取部213を設けた。これにより、血液貯留容器21Aの下端側から、無菌的に血液成分を採取できる。よって、血液貯留容器21Aに貯留された血液成分のうちの血球成分等の沈降成分を、他の成分を混入させることなく容易かつ無菌的に採取できる。
また、本実施形態を液性成分採取装置としての細胞懸濁液の採取装置に適用した場合には、沈降成分としての細胞を、他の成分を混入させることなく容易かつ無菌的に採取できる。
第3実施形態の血液採取装置100Bは、血液貯留容器21Bの上端に第2液性成分採取部233が設けられている点で第2実施形態と異なる。より具体的には、第2液性成分採取部233は、第1キャップ23Bに設けられた液性成分採取路234と、この液性成分採取路234に接続された液性成分採取チューブ235と、この液性成分採取チューブ235の先端側に接続されシリンジ等の液性成分採取装置(図示せず)との接続が可能な接続部236と、を備える。
接続部236は、液性成分採取チューブ235の先端に嵌合又は螺合されて接続される。接続部236としては、例えば、シリンジの先端側が挿脱可能なスリット部を有する弁体を備える混注ポートを好適に用いることができる。
血液貯留容器21Bの上端に第2液性成分採取部233を設けた。これにより、血液貯留容器21Bの上端側から、無菌的に血液成分を採取できる。よって、血液貯留容器21Bに貯留された血液成分のうちの血清や血漿等の上清成分を、他の成分を混入させることなく容易かつ無菌的に採取できる。
尚、第3実施形態では、血液貯留容器21Bに第1液性成分採取部213及び第2液性成分採取部233を設けたが、これに限らない。即ち、血液貯留容器には、第2液性成分採取部のみを設けてもよい。
第1実施形態の血液成分分離収容装置1は、図6及び図7に示すように、少なくとも血液由来の液性成分と血小板とを含む流動体を貯留する血液貯留部2と、該血液貯留部に貯留された前記流動体のうちの少なくとも一部の成分を収容する成分収容部3と、該血液貯留部2と該成分収容部3とを無菌的に連結する連結部4とを備える。

ボトムキャップ210は、筒状の嵌合部211と、この嵌合部に連続する底部212とを備える。嵌合部211の径方向の断面は、楕円形状を有しており、その外径は、血液貯留容器21の内径と略同一である。ボトムキャップ210は、嵌合部211が血液貯留容器21の下端部に嵌合されている。底部212は、その径が下方に向けて漸減した後、底面が平坦となった形状を有している。
第1収容容器22は、血液貯留容器21内に貯留される流動体を視認可能とする観点から透明性を有する材料から構成することが好ましく、また、比較的剛性の大きい材料から構成されることが好ましい。第1収容容器22を構成する材料としては、具体的には、ポリカーボネート、ポリエチレン、ポリプロピレン、ポリエステル、ポリメチルペンテン、メタクリル、ABS樹脂(アクリロニトリル・ブタジエン・スチレン共重合体)、PET樹脂(ポリエチレンテレフタレート)、ポリ塩化ビニル等の硬質合成樹脂が挙げられる。尚、硬質合成樹脂とは、後述する流体の注入による容器の内部空間の圧力変動により容易に変形しない程度の硬さを有する合成樹脂をいう。
第1接続部24は、その外径が第1収容容器22の開口における内径と略同一であり、第1接続部24の外周面に第1収容容器22の開口近傍が被嵌可能となされている。第2接続部25は、その外径が血液貯留容器21の開口の内径と略同一であり、第2接続部25の外周面に血液貯留容器21の開口近傍が被嵌可能となされている。
第1接続部24の外周面と第1収容容器22の開口近傍における内周面との間には、圧力調整空間26の密閉性を向上させるための密閉部材(図示せず)が介在配置されている。これにより、圧力調整空間26のより確実な密閉構造を確保できる。
密閉部材としては、例えば、シリコンゴムから構成される環状の部材を用いることができる。尚、密閉部材は、第1接続部24の外周面に被冠できる構成であればよく、素材としては、上記シリコンゴムに限られず、各種ゴム、各種エラストマー等の弾性部材を用いることができる。
また、密閉部材は、第2接続部25の外周面と血液貯留容器21の開口近傍における内周面との間に配置してもよい。
尚、第1キャップ23の下面における血液貯留容器21の内部空間に面する部分の形状は、図7に示すように、上方向に向かって漸次縮径してなる形状であるのが好ましい。更には、その頂部に貫通孔である成分導出路28が設けられてなる構成が好ましい。上記構成であれば、血液貯留容器21内で分離された血清を成分収容容器31に導出する際に、血清を無駄なく導出することが可能となる。
そして、注入手段により注入孔29から流体を注入することにより、圧力調整空間26が加圧される。この際、圧力調整空間26の外側を形成している第1収容容器22は可撓性を有さないため、可撓性を有する血液貯留容器21が圧力調整空間26の加圧の影響を受けてつぶれるように変形される。また、圧力調整空間26が加圧されることによってつぶれるように変形した血液貯留容器21は、加圧された圧力調整空間26を減圧することによって、元の形状に復元する。このように、圧力調整空間26の加圧や減圧によって血液貯留容器21を変形させることにより、後述する血清等の成分の成分収容部3への導出や採血を無菌的かつ容易に行うことができる。
成分採取部34は、成分収容容器31の底面に形成された成分採取口341と、この成分採取口341の下方に設けられた中空の円筒部342と、を備える。成分採取口341は、成分収容容器31の底面の一部に、薄膜状の厚みの薄い領域を設けることにより形成されている。円筒部342は、成分採取口341の形成された領域に、成分収容容器31の底面から下方に突出している。成分収容容器31内に収容された血液成分は、成分採取口341を注射針等の穿刺具にて破断穿刺することにより、採取することができる。この際に、成分採取口341の形成された領域には中空の円筒部342が形成されているため、穿刺具を確実に成分採取口341に穿刺することができる。
更に、成分収容容器31の底部に設けられた成分採取口341の位置と、第2収容容器32の内面底部の位置との間の距離が、前記穿刺具が収容可能な距離に設定されているのが好ましい。上記構成であれば、穿刺具を成分収容容器31の成分採取口341に穿刺した状態で、第2収容容器32内部に収容できる。穿刺具に適宜連通可能な開閉機構を有していれば、成分収容容器31内の血清を所望に応じて採取・保存が可能になる。
第1実施形態においては、第2収容容器32は、上述した第1収容容器22と同一の材料から構成され、また、その形状及び大きさも第1収容容器22と同一である。
第2収容容器32の上端近傍における外側面にも、第1収容容器22と同様にねじ山が形成されており、このねじ山の形状に対応するねじ溝を有するカバーキャップ(図示せず)を螺合可能となっている。
第3接続部35は、その外径が第2収容容器32の開口における内径と略同一であり、第3接続部35の外周面に第2収容容器32の開口近傍が被嵌可能となされている。第4接続部36は、その外径が成分収容容器31の開口の内径と略同一であり、第4接続部36の外周面に成分収容容器31の開口近傍が被嵌可能となされている。
尚、図7に示すように、第2キャップ33には、貫通孔29aが設けられているが、この貫通孔29aは設けなくてもよい。
通気路38には、通気チューブ7の一端が接続され、通気チューブ7の他端には、通気フィルタ71が接続されている。通気フィルタ71とは、気体は通過させるが液体は通過させず、また、細菌等も通過させない性質を有するフィルタである。即ち、通気フィルタ71が連結された通気路38からは、成分収容容器31内に無菌的に空気を出し入れさせることができる。通気路38と通気チューブ7とは、第2キャップ33における通気路38が形成されている部分の上面側に設けられた第4突起部332に通気チューブ7の端部を係合させることにより接続されている。
血液貯留容器21における血液の収容量は、好ましくは5~200mlであり、より好ましくは5~50mlである。血液貯留容器21は、具体的には、その内径が好ましくは10~30mmであり、その高さは好ましくは50~150mmである。
成分収容容器31における血液成分の収容量は、血液貯留容器21に収容された血液から分離された液性成分を確実に収容する観点から、血液貯留容器21における血液収容量の40~100%であることが好ましい。
また、第1収容容器22及び第2収容容器32として、公知の遠心分離管を用いることも好ましい。第1収容容器22及び第2収容容器32として公知の遠心分離管を用いることにより、後述する血液成分分離操作における遠心分離工程において、当該遠心分離管を使用可能な通常の遠心分離機を用いて簡易に分離操作を行うことができる。
第1収容容器22及び第2収容容器32として公知の遠心分離管を用いる場合、遠心分離管の容量は、遠心分離工程における汎用性を高める観点から、好ましくは5~50mlのものである。
また、貯留工程S1後においては、血液貯留部2に採取された血液が成分収容部3の方に流れ込まないように、連結チューブ41の経路がクランプ(図示せず)等を用いて血液貯留部2の根元側で閉鎖されている。貯留工程S1は、採血時における患者の体調等を考慮して、所要量を採取し終了される。ここでいう所要量は、患者の体格や体調に問題がない場合には5~50ml程度である。
尚、導出工程S6においては、上記圧力調整空間26の加圧に併せて、成分収容部3に設けられた通気チューブ7の先端に位置する通気フィルタ71から空気を吸引してもよい。通気フィルタ71から空気を吸引することにより、成分収容容器31内及びそれに連通する連結チューブ41内に陰圧を負荷し、血液貯留容器21から成分収容容器31への血清81の導入をより容易に行うことができる。
また、血液貯留容器21を縦長の筒状としたことにより、採取した血液が比較的少量であった場合にも、血液成分を容易に分離することができ、また分離した成分を血液貯留容器21から容易に導出することができる。このように比較的少量の血液でも血液成分の分離及び収容が容易に行えることは、採取可能な血液量が制限されているような対象者の血液から血清を調製する際に特に有効である。尚、ここで比較的少量の血液とは、具体的には5~50ml程度の血液量を指す。
また、圧力調整空間26の加圧によってつぶれるように変形した血液貯留容器21は、加圧された圧力調整空間26を減圧することによって、元の形状に復元する。従って、血液の採取前に、血液貯留容器21を圧力調整空間26の加圧によりつぶれるように変形させておき、採血時に、圧力調整空間26を減圧することによって血液貯留容器21を元の形状に復元させ、血液貯留容器21内を陰圧として採血を容易に行うこともできる。
第2実施形態の血液成分分離収容装置1においては、成分収容部3は、図14に示すように、成分収容容器31の外面と第2収容容器32の内面との間に形成されている空間に流体を注入可能な第2注入孔29aを備えている。第2実施形態においては、第2注入孔29aは、第2キャップ33に設けられている。詳細には、第2注入孔29aは、第2キャップ33に設けられた貫通孔であり、第2キャップ33における第4接続部36の外側でかつ第3接続部35の内側の領域に形成されている。そして、第2注入孔29aには、第2流体注入チューブ291aの一端が接続されている。第2流体注入チューブ291aの他端は、一端が注入孔29に接続され、他端が流体注入手段(図示せず)に接続された流体注入チューブ291の両端部間における所定の部位に連結されている。
例えば、第1キャップ23と血液貯留容器21又は第1収容容器22との接続、及び第2キャップ33と成分収容容器31又は第2収容容器32との接続は、第1実施形態及び第2実施形態においては、嵌合により接続されていたが、これらの接続は、例えば螺合であってもよい。
また、ボトムキャップ210を、側面を構成する可撓性を有する部材にて構成してもよい。
このように、ボトムキャップ210を、可撓性を有する部材で構成することにより、血液貯留容器21は、圧力調整空間26の加圧により下端部においても変形しやすくなり、血清等の成分の成分収容部3への導出をより容易に行うことができる。
また、血液貯留容器21から成分収容容器31への血清の移送は、第1実施形態及び第2実施形態においては、圧力調整空間を加圧することによって血液貯留容器21を変形させて行ったが、通気路から空気を吸引して成分収容容器31内及びそれに連通する血液貯留容器21内に陰圧を負荷することによって血液貯留容器21を変形させて行ってもよい。
また、血液貯留容器21の下端部と第1収容容器22の底部との間、及び成分収容容器31の下端部と第2収容容器32の底部との間にスペーサー(図示せず)を配置するような構成であってもよい。
上記構成であれば、本装置の血液成分分離操作における遠心分離工程の際に、血液貯留容器21、成分収容容器31のそれぞれに負荷される荷重を軽減することが可能となる。
しかしながら、本構成は、第2キャップ33の頂部に貫通孔である通気路38が設けられてなる構成としてもよい(図15参照)。
これにより、通気路38から吸気を行って成分収容容器31内の減圧操作を行う場合に、成分収容容器31内に収容された成分(例えば血清)を吸引することなく、減圧操作を行うことができる。
