Claims (15)
- 患者に呼吸ガスを供給し、密閉チャンバー内に設けられた可変容量部を含む呼吸回路と、前記可変容量部の容量を可変するため、前記密閉チャンバーが供給ガスによって加圧されるように前記密閉チャンバー内に設けられたガス供給通路と、所定の状況で、前記供給ガスが弁手段(酸素置換弁)を介して前記呼吸回路に直接入ることができるように設けられたガス供給用代替通路とから成り、前記密閉チャンバー内のガス供給通路は、ガスが前記密閉チャンバー内に入った結果、前記弁手段が閉じ状態に一層確実に偏移される人工呼吸装置。
- 請求項1に記載の人工呼吸装置であって、ガスが前記チャンバーに入る結果、前記弁手段の前記密閉チャンバー側の圧力が減少するように、前記密閉チャンバー内のガス供給通路が指向される人工呼吸装置。
- 請求項2に記載の人工呼吸装置であって、前記弁手段の前記密閉チャンバー側圧力は、前記呼吸回路側圧力に対して僅かに低くなっている人工呼吸装置。
- 請求項1乃至3のいずれかに記載の人工呼吸装置であって、前記弁手段を閉止状態に一層堅固に付勢する効果は、呼吸サイクルの吸気過程の初めに一時的に生じるようになっている人工呼吸装置。
- 請求項1乃至4のいずれかに記載の人工呼吸装置であって、ガス供給は、前記弁手段との導管接続部から離れるように前記チャンバー内に向けられる人工呼吸装置。
- 請求項5に記載の人工呼吸装置であって、前記弁から離れるように及び/又は前記可変容量部に向かうように前記供給ガスを指向するために、前記密閉チャンバーに邪魔板又は偏向器が設けられている人工呼吸装置。
- 請求項5に記載の人工呼吸装置であって、ガス供給管は、前記チャンバーと連通する出口端を有し、前記弁手段との管接続部を越えて延びている人工呼吸装置。
- 請求項1乃至7のいずれかに記載の人工呼吸装置であって、前記弁手段は、弁を閉じた状態で弁座に乗るように設けられた弁エレメントを含む人工呼吸装置。
- 請求項8に記載の人工呼吸装置であって、前記弁エレメントは、弁を開いた状態で前記弁座から持ち上がるように設けられた人工呼吸装置。
- 請求項1乃至9のいずれかに記載の人工呼吸装置であって、前記弁手段は、前記可変容量部が最大の収縮状態にあるとき、開くようになっている人工呼吸装置。
- 請求項1乃至10のいずれかに記載の人工呼吸装置であって、前記可変容量部は、可撓性バッグ又はポーチから成っている人工呼吸装置。
- 請求項1乃至11のいずれかに記載の人工呼吸装置であって、前記可変容量部は、伸縮性ベローズ装置から成っている人工呼吸装置。
- 請求項1乃至12のいずれかに記載の人工呼吸装置であって、患者にガス混合物を送給するのに用いられ人工呼吸装置。
- 請求項1乃至13のいずれかに記載の人工呼吸装置であって、前記可変容量部は、可撓性バッグ又はポーチから成り、前記可変容量部の壁は、拡張状態の前記可撓性バッグ又はポーチ部分に隣接して入れ子式には入り又は乗るようにした凹状の表面を含む人工呼吸装置。
- 患者に呼吸ガスを供給し、密閉チャンバーの内部に設けられた可変容量可撓性バッグ又はポーチを含む呼吸回路と、前記バッグ又はポーチの容量を可変するため、前記密閉チャンバーが供給ガスによって加圧されるように前記密閉チャンバー内に設けられたガス供給通路とから成り、前記密閉チャンバーの壁が、拡張状態の可撓性バッグ又はポーチの隣合う部分を嵌め込み又は抱え込む、即ちこの部分の形状に一致したへこんだ表面を含んでいる人工呼吸装置。
