Description
本発明は、オゾンで体液を処理するための方法及び装置に関する。より詳細には、本発明は、オゾンで血液を処理するための方法及び装置に関する。
オゾンは強力な酸化剤で、殺菌剤として使用されている。腐食性で反応性の高いオゾンの性質にもかかわらず、血液中の特定の感染性因子を殺菌又は不活性化するためのオゾンの使用が検討されている。例えば、米国特許出願公開第2005/0189302A1号は、気液の物質移動を最大にする気液接触装置において、血液をオゾンに曝露することによって血液中のウイルスを不活性化する方法を開示している。接触装置は、血液の薄膜を形成するための球体又はロッドを含み、処理は好ましくは周囲温度で行われる。国際公開第2011/162805号は、米国特許出願公開第2005/0189302 A1号に開示されているものと同様の気液接触装置を用いて血液をオゾン・酸素混合物に晒すことによって、血液中の感染性プリオンタンパク質を不活性化する方法を開示する。
以下、添付の図面を参照して、本発明の特定の実施形態を説明する。もっとも、本発明は、多くの異なる形態で実施することができ、本明細書に記載の実施形態に限定されるものと解釈すべきではない。むしろ、これらの実施形態は、本開示が詳細かつ完全であり、本発明の範囲を当業者に完全に伝えるように提供される。添付の図面に示される実施形態の詳細な説明に使用される用語は、本発明を限定することを意図するものではない。図面において、同様の番号は同様の要素を示す。
