Abstract
Description
本願は、参照することによってその全体として本明細書に組み込まれる、2018年6月27日に出願された、米国仮出願第62/690,403号の優先権を主張する。
開示される実施形態は、医療デバイスの分野に関し、特に、種々の形態の体外生命維持のための装着可能デバイスおよびそのようなデバイスを採用する方法を含み得る。いくつかの実施形態では、装着可能デバイスは、体外膜酸素化と体外持続的腎代替療法を組み合わせるが、多臓器不全治療/支援の一部として、肝不全、心不全、ならびに選択的脳灌流、およびそれらの組み合わせのための移動式支援にも等しく適用されるであろう。本デバイスはまた、エンドユーザ自己操作特性を用いた自宅および医療設備外での使用も支援し得る。
体外生命維持(ECLS)は、複数の形態の体外救援療法を含む。典型的には、急性の可逆的心不全または呼吸不全を患う患者における長期体外心肺バイパスの使用を指している。技術が、進歩するにつれて、肝臓、腎臓、心臓支援等のガス交換以外の臓器支援機能が、ECLSによって提供されている。加えて、ECLSは、脳死ドナーにおける臓器摘出のため、移植のための臓器の生存率を延長させるためにも使用されているだけではなく、そのような移植を待機している患者のために肺機能を提供するためにも使用されている。
開示される実施形態は、装着可能で移動式の自宅または外側病院外でのモジュール式の臓器支援、臓器代替、および持続的体外生命維持を可能にする、デバイスを含み得る。本デバイスは、例えば、意識がある状態で、挿管および機械的に換気される、麻酔される、無力化される、および寝たきりにされる必要なく、呼吸支援を患者に提供し得る。本デバイスはまた、肺膜の使用を通して、例えば、歩行可能体外CO2除去、部分的酸素化、および部分的肺支援を可能にし得る。本デバイスの開示される実施形態はまた、例えば、透析膜の使用を通して、代謝物、サイトカイン、炎症性媒介物、病原体、および他の血液含有化合物の歩行可能または自宅での使用による体外除去を可能にし得る。本デバイスはまた、肺膜および透析膜または任意の順序においてデバイスに接続される他の臓器支援デバイスの付随使用を可能にし得る。開示される実施形態は、臓器支援または臓器代替モジュール、デバイス、および/または構成要素を提供し得る。開示される実施形態は、肺、腎臓または腎臓部、肝臓、心臓、脳(脳専用の選択的灌流を介して)、腸(例えば、胃または他の腹部臓器)、またはそれらの組み合わせのための臓器代替または臓器支援を提供し得る。加えて、開示される実施形態は、支援の任意の組み合わせまたは群化において、任意の量の臓器のための統合された部分的または全体的臓器支援、臓器系支援、多系統臓器支援、および選択的臓器特有または組み合わせ臓器系支援を提供し得る。開示される実施形態は、脳死ドナーにおける臓器摘出および移植のための臓器の生存率の延長を提供し得る。例えば、移植を待機している患者のための肺機能または他の身体機能を延長させる。
ここで、本開示の本実施形態(例示的実施形態)が詳細に参照され、その実施例は、付随の図面に図示される。
