Description
図1は、流体回路アセンブリ10を形成するための第1および第2の流体回路またはサブアセンブリそれぞれ16および18の一部として図示されている二つの流体導管の14a,bを接合する接続または合体12を含んでいる、流体回路アセンブリ10の一例を図示する。各流体流回路またはサブアセンブリ16および18は、追加のチューブ、容器、バルブ、分離チャンバー、および特定の用途に望まれる他の選択された処理または貯蔵装置を含むことができる。図示するように、各回路またはサブアセンブリの流体導管14a,bは、各自一以上のチューブ流体流回路20a,bおよび流体容器22a,bを含むことができるが、しかし各回路またはサブアセンブリの正確な部品は用途が必要とするように変化することができ、そして流体容器は一方または両方の流体導管において任意である。
シーリング部材26a,bは、任意の適切な構造、形状または寸法のものでよく、そして接着剤、溶剤または熱溶接によって導管14a,bへ取り付けることができ、そして同じまたは異なる構造もしくは材料のものでよい。後でもっと詳しく記載するように、シーリング部材は、接続操作の間導管の開放端の材料が溶融する上昇温度へ加熱される少なくとも一つの加熱エレメントを含むことができる。前もって滅菌された流体流回路またはサブアセンブリ16および18間に無菌接続を形成するため、上昇温度は、好ましくはシーリング部材または少なくともシーリング部材が導管の無菌の内腔へ露出される部分の滅菌を生じさせるのに十分に高い。
図4−8から見られるように、図示したシーリング部材26a,bは、各自細長い長方形のパネルであり、そして好ましくは、しかし必要ではないがパネルの一端近くの偏心位置のような位置においてそれぞれの導管14a,bの一端へ接合されている。この位置決めは、パネルの残りの部分を後で記載する目的のため把持または他のように係合する容易性を残す。
図4−9は、流体流サブアセンブリ16および18が個々に組み立てられ、そして所望により事前滅菌された後、無菌流体流アセンブリを形成するためそれらがどのように合体されるかを図解する。図4を参照すると、導管14a,bは、各自導管の先端を取り付け具から突出させてそれぞれの溶接もしくは接合取り付け具またはホルダー(この図には示さず)上に一時的に取り付けることができる。溶接または接合取り付け具は任意の適した特定構造または材料のものでよいが、しかし好ましくはシーリング部材26a,bの遠方表面を突き合わせ関係にして導管14a,bの開放端を軸方向に整列させるように構成される。
図10−15は、流体流導管14または流れ回路または流体流サブアセンブリ間に好ましくは無菌態様で接続を形成するための記載した方法を実施するための一般に40で指示した器具または装置の一つのバージョンを図示する。概して、装置40は二つの導管ホルダー42a,bと、パワー源44(図10に見られる)と、そしてシーリング部材ホルダーまたは引っ張り具46とを含み、装置の操作は、例えば後で記載する作業のシーケンスまたはその適切な一部を実行するようにプログラムされたプログラム可能なマイクロプロセッサーを使用するコントローラーによって自動的にコントロールすることができる。
今や図10−15に示した装置を使用する無菌接続の形成方法へ転ずると、図10は装填ステップが取られていない装置を示している。導管ホルダー42aおよび42bは装填位置に離れており、そしてシーリング部材ホルダー46は導管ホルダーから離れている。
図16および17は、無菌接続用途に対して多分好ましい構造として現在意図されている、導管14a,bとシーリング部材26a,bの具体例を図示する。そこに示されているように、導管14a,bは内部の内腔もしくはボアを有する中空チューブ状構造であり、そしてポリプロピレン(PP)材料か、または導管が溶融した時滅菌温度に達しおよび/または越えたことを確実にすることを助ける、好ましくは滅菌温度またそれより高い溶融温度を有する他の適切な材料でつくられる。チューブの寸法は特定の用途に必要なように変動し得る。図示したサンプルは、約4.1mmの内径と、約6mmの外径を有する。
図18は、流体回路アセンブリ70を形成するため、二つの流体流回路またはサブアセンブリ74を合体する接続アセンブリ72を含んでいる流体回路アセンブリ70の一例を図示する。各流体回路またはサブアセンブリ74および76は、特定の使用または最終用途のため記載したような、図示しないチューブ、容器、バルブ、分離チャンバーおよび他の選択した流体処理また貯蔵装置を含むことができる。最も広い意味でこの具体例は無菌接続に限定されない。しかしながらそれは、使い捨て無菌医療用流体流アセンブリのような、無菌流体流アセンブリまたはシステムの前もって滅菌された部品、流れ回路またはサブアセンブリ間に無菌接続の形成に特別の用途および利益を有することが認められるであろう。
好ましくは二つの前もって滅菌された流体流回路またはサブアセンブリの無菌接続による流体流アセンブリ70の形成方法は、本主題の特に有利な局面の一つである。この方法は、商業的販売のための製品の製造コースにある製造設備において、顧客またはユーザーが所望の構成に製品部品を接合することを許容する現場において、または他の目的のような任意の適切な環境において使用することができる。得られる流れ回路アセンブリは、血液、食塩水およびデキストロースのような静脈内溶液、無菌水、抗凝固剤、血液成分保存液または任意の他の所望の流体を含む医療用流体のものであることができる。もっと広い点においては、流体は気体であることもできる。
図26および27はシーリング部材の人手による運動に便宜を図る他の具体例を示す。もっと詳しくは、図26は接合すべき第1および第2の流体流回路またはサブアセンブリ120,122を示す。これら流体流回路は好ましくは事前に滅菌され、そして無菌性を保存する態様で合体される。流体流回路120はチューブ124と、剛直なハウジング126と、熱溶融し得る末端チューブセグメント128と、そして末端チューブセグメントの端をシールするシーリング部材(パネル)130を含んでいる。ハウジング126はチューブ124へ取り付けのため入口とそして末端チューブセグメント128へ取り付けのための出口を有する内部流体流回路132を有している。
本主題の他の局面に従えば、ここの滅菌/溶接時間は、全体または適切な部分において抗微生物性を有するシーリング部材を使用する上の装置、システムおよび方法のどれにおいても短縮することができる。有意な抗微生物性を有する表面を持ったシーリング部材の使用は、理論上、他のタイプのシーリング部材に比較して滅菌加熱時間を50%またはそれ以上短縮することが可能である。
