- オリフィスから酸素ガスを噴射するノズル部材と、
前記ノズル部材のオリフィスと対応する位置に配置され該オリフィスから噴射された酸素ガスの気流によって水を吸引する吸引孔と吸引した水を微細なエアロゾルとするバッフルとを有するエアロゾル形成部材と、
前記ノズル部材のオリフィスからの酸素ガスの噴射に伴って空気を吸引する空気吸引孔と、を有し、
前記ノズル部材は、該ノズル部材の軸芯に沿って前記エアロゾル形成部材に向けて酸素ガスを噴射するオリフィスが形成され、且つノズル部材の側壁に酸素ガスの流出孔が形成され、更に、ノズル部材の外周であって前記流出孔に対向する位置にノズル部材に酸素ガスが供給されていない状態では流出孔を閉鎖し且つノズル部材に供給された酸素ガスの圧力に対応して流出孔を開く弁を設けて構成され、供給された酸素ガスの圧力に対応して該酸素ガスをオリフィスから噴射し又はオリフィスから噴射すると共に酸素ガスの流出孔から流出させるように構成されていることを特徴とするネブライザー。 - 前記ノズル部材の外側面には側壁に形成した酸素ガスの流出孔と対応する位置にリング状の溝が形成されると共にフランジを介して前記リング状の溝のオリフィス側に溝が形成され、前記オリフィス側の溝のノズル部材の先端側に形成されたフランジに該オリフィス側の溝から酸素ガスを流通させる孔が形成され、且つ前記弁は弾性と可撓性を有し且つノズル部材の外径と略等しい内径を有するチューブからなり、該チューブがノズル部材の外周に嵌め込まれて一端が側壁に止め付けられると共に他端が前記酸素ガスを流通させる孔が形成されたフランジに到達していることを特徴とする請求項1に記載したネブライザー。
