Abstract
【選択図】図2
Description
酸素は、呼吸器系又は他の病気を患う入院患者に処方される最も一般的な薬である。鼻カニューレ又はフェースマスクを介した酸素の送出は、息切れを訴える患者に有益である。吸入酸素濃度を増加することによって、酸素治療は、呼吸する労力が軽減され、結果として生じている低酸素症(組織内の酸素が低レベルであること)を矯正する。
ガスを通して引き込む入口を有するガス供給源と、
排気口を有する加湿チャンバを含み、ガスが入口から加湿チャンバを通り出口を出る加湿手段と、
ガス供給源吸気口又はその周囲に設けられ酸素又は他のガスをガスに加えることを可能にするマニホルドと、を備えている。
好ましくはマニホルドは実質的に矩形である。
好ましくはガス供給源は、呼吸支援装置を通って流れる酸素濃度を感知することができる内部センサを含む。
好ましくはガス供給源は、制御装置によって制御される表示装置を含み、該制御装置は、酸素濃度を表示装置上に表示及び更新する。
本発明の呼吸支援装置は、好ましくはガス供給源及び加湿装置を備え、又は後から組み込み可能であるマニホルドを含む。マニホルドによって、酸素濃縮器からのガスをガス供給源及び加湿装置を通る流れ、最も一般的には空気と組み合わせることが可能となる。次に、酸素及び他の呼吸ガス(空気)の組み合わされた出力が加湿される。
本発明のこの呼吸支援装置及びマニホルドは、ガス供給源及び加湿装置の入力空気流に酸素を加える安全な方法を提供する。酸素をマニホルドに送る管体からの全酸素出力は、装置の使用中に該装置中に引き込まれるが、装置のスイッチが切られると、マニホルド中に送られる酸素はアパーチャ16、17を通って分散し、従って、装置4の外側に留まる。従って、酸素は装置(例えばブロワなどのガス供給源)中に蓄積せず、火災の危険を生じない。その結果、マニホルドは、ブロワ又は呼吸導管内でスパークが発生した場合の火災リスクを低下させる。
