Description
本特許出願は、参照により本明細書に組み込まれている、2014年8月14日に出願したインド仮出願第3988/CHE/2014号、名称「DEVICE AND METHOD FOR REMOVAL OF SECRETIONS TO PREVENT VENTILATORASSOCIATED PNEUMONIA」の優先権を主張するものである。
本明細書で言及されているすべての刊行物および特許出願は、それぞれの個別の刊行物または特許出願が、本明細書に組み込まれることが特に、また個別に指示されている場合と同じ範囲にわたってそっくりそのまま本明細書に組み込まれる。
一般に、流体管理システムは、流体管路、センサー、コントローラおよびコントローラ用回路、および洗浄コンポーネントを備え得る。コントローラは、典型的には、流体管理システムコンポーネントの動作を監視する流体管理システムの一部分である。コントローラは、気管チューブに沿った領域から流体を吸引して除去する場合には、流体取り出し、または気管チューブが挿入されている口腔または呼吸管の特定の領域の洗浄の場合には、流体送達を調節するための回路およびマイクロコントロールを含むことができる。コントローラは、呼吸挿入デバイスを流体管理システムの感知、吸引、およびポンプ動作コンポーネントに連結する流体管路を接続し、維持する弁を含み得る。使用時に、コントローラは、感知、吸引、およびポンプ動作サイクルを調整するための回路を含むマイクロコントロールも備え得る。コントローラは、定期的に、自動的に、および独立して、圧力、吸引、または感知を各流体管路に施す。
述べたように、上で説明されている流体管理システムは、呼吸挿入デバイスに結合され得る。図17〜図30は、流体管理システムに接続されている呼吸挿入デバイスさらには企図されている呼吸挿入デバイスの異なる実施形態を説明している。
次の段落では、流体管理システムを呼吸挿入デバイスとともに使用する方法について説明する。使用者は、複数の開口部を有する呼吸挿入デバイスを被験者の呼吸管内に挿入する作業を、第1の開口部が口腔(たとえば、被験者の舌根の近く)に位置決めされ、第2の開口部が被験者の中咽頭に位置決めされ、第3の開口部が被験者の声門下部に位置決めされるように行うことができる。ある場合には、呼吸挿入本体部は、既存の気管チューブに取り付けられ、他の場合には、気管チューブを組み込んだ呼吸挿入本体部は、患者の気管に新たに挿入される。
