- 少なくとも1つの器具入口(11a)と、器具出口(15a)と、前記器具入口(11a)と前記器具出口(15a)の間の呼吸ガス経路(16a)とを有する人工呼吸器具(10)であって、前記呼吸ガス経路(16a)は、少なくとも1つの吸気の呼吸ガス経路(16a)および少なくとも1つの呼気の呼吸ガス経路と、呼吸ガス駆動部(12a)と、逆止め弁(13a)と、切換弁(14a)とを備え、前記逆止め弁(13a)は、前記吸気の呼吸ガス経路(16a)内に配置され、かつ、前記器具出口(15a)から前記器具入口(11a)への方向で呼吸ガス流を妨げるように構成され、前記切換弁(14a)は、前記呼気の呼吸ガス経路の遮断/障害の場合において前記吸気の呼吸ガス経路(16a)を介して患者の呼気を放出するように、かつ、前記器具出口(15a)から前記器具入口(11a)または別個の器具開口部への方向で呼吸ガス流を少なくとも一時的に可能にするように構成され、
少なくとも1つの前記切換弁(14a)は、前記逆止め弁(13a)のバイパス(17)を形成し、かつ、前記バイパス(17)を開放および/または閉鎖するようにセットアップされ、前記切換弁(14a)は自動的に切換可能なようにセットアップされ、
前記呼吸ガス駆動部(12a)は、前記逆止め弁(13a)と前記器具出口(15a)の間に配置されるとともに、前記器具出口(15a)の方向に呼吸ガスを送出するようにセットアップされ、
前記バイパス(17)は、前記器具入口(11a)と前記逆止め弁(13a)の間で前記切換弁(14a)へと分岐し、前記逆止め弁(13a)と前記呼吸ガス駆動部(12a)の間で再び前記呼吸ガス経路(16a)に連通し、
前記逆止め弁(13a)と前記器具出口(15a)との間に流動測定装置(18a)が配置され、前記流動測定装置(18a)は、前記呼吸ガス経路(16a)内の呼吸ガスの流動もしくは容積または圧力を検出し、患者に供給される呼吸ガスまたは患者から放出される呼吸ガスの流動もしくは容積または圧力に関するフィードバックを前記人工呼吸器具(10)へ供給し、かつ、前記流動もしくは容積または圧力に基づいて前記切換弁(14a)を自動的に切り換えるようにセットアップされる、人工呼吸器具(10)。 - 前記切換弁(14a)は、前記逆止め弁(13a)に対して前記バイパス(17)に配置されることを特徴とする、請求項1に記載の人工呼吸器具(10)。
- 前記バイパス(17)に追加して、第2の器具入口(11b)と少なくとも1つのさらなる逆止め弁(13b)とを含み、共通の前記器具出口(15a)の前で前記第1の呼吸ガス経路(16a)に連通する第2の吸気の呼吸ガス経路(16b)が構成されることを特徴とする、請求項1または2に記載の人工呼吸器具(10)。
