Abstract
【解決手段】比例障害弁(POV)は、入口、出口、及びバイパスを含む。ステッパモータにより制御される活栓は、患者への空気流の制御を可能にしながら、タービンを一定のRPMで動作させるようにして、バイパス及び出口を介して空気の流れを送る。人工呼吸器はまた、空気流制御を改善し、製作が容易な吸気弁アセンブリ及び呼気弁アセンブリを含む。吸気弁は、圧力センサが正確に空気流を測定可能にするためのオリフィスディスクを含む。呼気弁アセンブリは、乱流を低減し、センサ精度を高める翼を含む。呼気弁アセンブリは、凝縮が形成される可能性を低減するために、タービンを冷却させた暖かい空気をアセンブリ上に吹き付ける。人工呼吸器はまた、冗長性を有する電力源を備えた改善された電源を含む。
