放射線滅菌に容器をさらすステップと、

容器を収容するチャンバをガス滅菌にさらすステップと、
を含む。
体液排液システムのチャンバ内に放出されることとなる表面保護流体を収容する容器を用意するステップであって、容器が放射線滅菌にさらされたものであり、表面保護流体は、チャンバの内方表面に付着し、かつ他の流体が内方表面と接触するのを防止する、ステップと、
体液排液システムのチャンバ内に容器を挿入するステップと、
容器を収容するチャンバをガス滅菌にさらすステップと、
を含む。
本発明の文脈において、以下の用語および表現は、以下の意味を有して使用される。
尿などの体液は、特に体液測定システムなどの体液排液システムの内部の表面に対してなど、人造表面に対して非常に侵攻的である場合がある。本発明による体液排液システムは、例えばカテーテル、測定チャンバ、中間チャンバ、または分析チャンバなどのチャンバ、および収集バッグなどの、患者のドレナージに連結された配管システムを備えた閉システムであり得る。体液排液システムは、患者の身体の外部に、すなわち体外に位置する。配管システムは、患者から、静電容量非接触センサシステムが測定チャンバの壁部を通して信号を感知し、その容量を算出する測定チャンバなどのチャンバに体液を送る。好ましくは、チャンバ壁部は、医療用品用において容易に入手できる剛性ポリマー材料である。好ましくは、体液は、測定または分析された後に、収集バッグ内に収集される。好ましくは、かかる収集バッグは、可撓性ポリマー材料から作製され、チャンバの容積よりも著しく大きな容積を有する。
次に図1aおよび図1bを参照すると、本発明は、測定機能性および測定精度などの持続的な機能性および精度を改善するために体液排液システムの表面に物質を塗布することを教示する。
体液排液システムの内方表面に油混合物を塗布するステップ
を含む。
体液排液システムの内方表面に油混合物を塗布するステップ
を含む。
体液排液システムのチャンバ内に放出されることとなる表面保護流体を収容するチャンバを用意するステップと、
放射線滅菌に容器をさらすステップと、
体液排液システムのチャンバ内に容器を挿入するステップと、
容器を収容するチャンバをガス滅菌にさらすステップと、
を含む。
体液排液システムのチャンバ内に放出されることとなる表面保護流体を収容する容器を用意するステップであって、この容器が、放射線滅菌にさらされたものである、ステップと、
体液排液システムのチャンバ内に容器を挿入するステップと、
容器を収容するチャンバをガス滅菌にさらすステップと、
を含む。
好ましくは、例えば容器などの油放出デバイスは、水溶性材料から作製されたカプセル壁部を備えるカプセル105として実装される。カプセルは、ある量の油をカプセル封入する。好ましくは、カプセルは、円筒状、半球端部を有する円筒状、球状、楕円状、長円状、または丸み正六面体形状もしくは丸みタブレット形状、または目的に適した任意の形状からなる群より選択される形状のものである。
油は、用途選択された油である。粘度は、最大で600センチストークス(cSt、mm2/s)であり得る。好ましくは、粘度は、200〜600センチストークス(cSt、mm2/s)の間である。粘度は、300〜400センチストークス(cSt、mm2/s)の間であることがより好ましい。粘度は、345〜355センチストークス(cSt、mm2/s)の間であることがさらにより好ましい。最大で600cStのまたはこれらの間の粘度を有する油が、体液上に広がり、体液上に油の層を形成する。油は、体液の表面を覆って広がる。かかる粘度を有する油は、体液上に広がり、体液排液システムの内包表面と接触状態になり、上述の方法で体液排液システムの内方表面に塗布される。粘度が過度に高いと、結果として油は、体液の表面上に広がらず、そのため体液排液システムの内方表面と接触状態にならず、また体液排液システムの内方表面に塗布されることもない。代わりに、粘度が過度に高い油は、蓄積し、塊を形成する。
また、本発明者らは、上記に開示した用途選択された油が、カプセル以外の方法を利用して体液処理システム表面に塗布され得ることを一般化した。したがって、本発明の目的を達成するために、油の特定の使用がなされる。用途Yにおける化合物Xの使用が開示される。ここで、化合物Xは、シリコーン流体および鉱油またはそれらの混合物からなる群より選択される、ならびに最大で600cStの、好ましくは300〜400cStの間の、より好ましくは300〜400cStの間の、さらにより好ましくは345〜355cStの間の、および最も好ましくは約350cStの粘度を有する90〜100%の油を含む油混合物であり、用途Yは、体液処理システムまたは体液排液システムの管腔表面の処理である。ここで、「処理」という用語は、油が、体液処理システムの管腔空間内への油の配給方法にかかわらず、当該表面に塗布される活動を意味する。好ましい方法としては、管腔空間内への油の注入、噴霧、塗装、浸漬、液浸、放出、および水性流体の補助による配給が含まれる。水性流体は、体液であってもよい。特に、上述のようにカプセルからの油混合物の放出を伴う分配が好ましく、放出された油混合物が体液と共に管腔空間内に輸送される、かかるカプセルからの分配がさらに好ましい。特定の一実施形態では、容器はシリンジであり、表面保護流体はシリンジ内に収容される。この場合には、表面保護流体は、例えばシリンジのプランジャを押すことなどにより、シリンジからチャンバへと手動により放出される。好ましくは、表面保護流体は、排液システムの動作開始と連携してチャンバ内に配給される。この場合には、好ましくは、表面保護流体は、管腔空間内に輸送され、上述のように体液と共に管腔空間の表面を覆って広がる。
好ましくは、チャンバの材料は、医療用品用のポリマーである。より好ましくは、チャンバの材料は医療用品用のポリマーであり、このポリマーは親油性表面を有する。最も好ましくは、チャンバの材料はポリプロピレンである。親油性材料は、油をはじく撥油性材料とは対照的に、チャンバ表面に油を保持することが試験によって判明している。したがって、撥油性材料を用いた場合には、油は、時間と共にやや迅速に体液によって洗い流される。
