Description
− 主チャネルを形成し、その遠位端を介して患者の気道に連通されている管状要素であって、その近位端は上記の患者に近い側に位置し、患者の呼吸系が上記の主チャネルを介して外側に連通されているものと、
− 呼吸用気体が供給され、上記の主チャネルに開口している補助チャネルと、
− 上記の補助チャネルを介して噴射された呼吸用気体の噴射流を上記の主チャネルの内側で相互に確実に収斂させる偏向手段と
からなり、
上記の管状要素が少なくとも1つの側方安全オリフィス(開口部)を備え、このオリフィスは上記の呼吸用気体の噴射流の収斂点に少なくともほぼ対向するその側壁を貫通し、上記の偏向手段の下流に位置する上記の呼吸用気体の噴射流の収斂点にほぼ対向する部分で環状要素の側壁を貫通して、主チャネルの一部分を外側に連通することができることを特徴とする。
− 本発明による装置が患者の顔に載せられるようになされたマスクの呼吸用気体入口および出口連結ピース(片)(この連結ピースは上記のマスクと一体あるいは着脱自在に取り付けられている)を構成する場合、上記の側方安全オリフィスそれ自体は外側に位置し、主チャネルの下流部分を直接周囲の空気と連通させ、この場合、上記の呼吸用気体の噴射流により生じ、上記の側方安全オリフィスを介して聞こえる騒音を、このオリフィスを、例えば、繊維製材料あるいは多孔性材料製の包みあるいはパッドで覆うことにより遮蔽することが望ましい。
− 反対に、本発明による装置が、患者の気道内に少なくとも部分的に導入されるようになされた(鼻腔あるいは口腔)プローブである場合、上記の側方安全オリフィスはそれ自体は上記の気道内に位置する。その際、上記の側方安全オリフィスは導管を介して周囲の空気に連通させるのが望ましい。そのような導管は、風船を形成し、上記の管状要素を囲む可撓性覆いにより形成されるのが望ましく、上記の側方安全オリフィスは上記の覆いに開口し、この覆い自体は、上記の管状要素の近位端で周囲の空気に開口する。そのような覆いは患者の粘膜の上記のプローブとの擦れに対し保護でき、上記の呼吸用気体噴流の騒音を少なくとも一部分吸収する役目も果たすことができる。然し、又、ここでも、上記の騒音を遮蔽するため繊維製あるいは多孔性材料で構成されたいずれかの補完手段を設けることができる。
Claims (6)
- 人工呼吸装置は、
− 主チャネル(7、27)を形成し、その遠位端(5D、25D)を介して患者の気道に連通されている管状要素(5、25)であって、その近位端(5P、25P)は上記の患者の外側に位置し、患者の呼吸系が上記の主チャネル(7、27)により外側に連通されているものと、
− 呼吸用気体が供給され、上記の主チャネル(7、27)に開口している補助チャネル(9、29)と、
− 上記の補助チャネル(9、29)を介して噴射された呼吸用気体の噴射流を上記の主チャネル(7、27)の内側で相互に確実に収斂させる偏向手段(8、28)と
からなり、
上記の管状要素(5、25)が少なくとも1つの側方安全オリフィス(開口部)(12、32)を備え、このオリフィス(12、32)は上記の偏向手段(8、28)の下流に位置する上記の呼吸用気体の噴射流の収斂点(C)にほぼ対向する部分で環状要素(5、25)の側壁を貫通して主チャネル(7、27)の一部分を外側に連通することができることを特徴とする人工呼吸装置。 - 上記の主チャネルの下流部分(7B、27B)が上記の側方安全オリフィス(12)を介して外側に直接連通していることを特徴とする請求項1に記載の人工呼吸装置。
- 上記の側方安全オリフィス(12)を通過する呼吸用気体噴流の騒音を遮蔽するための繊維製あるいは多孔性材料(13)を備えることを特徴とする請求項2に記載の人工呼吸装置。
- 上記の側方安全オリフィス(32)を外側に連通させる導管を備えることを特徴とする請求項1に記載の人工呼吸装置。
- 上記の導管が上記の管状要素(25)を囲む可撓性覆い(43)により形成され、この覆い(43)の近位端で外側に開口していることを特徴とする請求項4に記載の人工呼吸装置。
- 上記の主チャネル(7、27)の上流部分(7A、27A)が、この上流部分(7A、27A)の密封を阻止する内部障害物(15、35)を突出させていることを特徴とする請求項1から5のいずれか1項に記載の人工呼吸装置。
