Description
a)呼吸筋が弱く、かつサーファクタントレベルが低いことによって、肺を開くのには不十分な圧力しか生じず、蘇生される場合、肺胞を開いた状態に保つ努力ですぐに疲れる。
b)肺胞を支持するには発育不十分の内部組織構造。
c)肺液の除去の遅れ。非常に早産の新生児では、流体は、出生後も肺胞に分泌され続ける可能性がある。
d)柔らかい胸壁、水平な肋骨、および平らな横隔膜が、深吸気量の低下に寄与する。
e)酸素に富む血液と酸素が少ない血液すなわち脱非酸素血液(deoxygenated blood)との混合により、肺における血圧を上昇させ、血管から肺組織への流体の移動量を増やす。血中酸素濃度の低下によって組織内の酸素が欠乏し、呼吸筋の筋力を低下させる。
f)頚筋が弱くかつ首に脂肪がないことによって上気道の安定性を低下させるため、吸気時の虚脱が発生し得る。
g)虚脱した、損傷した肺胞は、タンパク質を分泌し、サーファクタントの機能を低下させる。
圧力調整機器を、ガス経路に流体連通する第1の出口に接続するためのマウントであって、第1の出口を、少なくともある程度、選択的に遮断する弁部材を保持するように構成されたマウント;
マウントに可動に係合した制御部材であって、制御部材の操作によって、弁部材の特性を調整する、制御部材
を含み、
弁部材は、経路内のガスの圧力が、選択したレベルを下回るとき、第1の出口を少なくとも部分的に遮断するように構成されており、および前記ガスの圧力が、前記選択したレベルを上回るとき、前記ガスの少なくとも一部分が前記第1の出口から流出できるようにし、および
前記特性が、前記選択したレベルを含み、それにより、制御部材を操作することによって、圧力のレベルを最大レベルと最小レベルとの間で調整し、その調整レベルで、弁部材は、前記ガスの少なくとも一部分またはそれよりも多い部分を前記第1の出口から流出できるようにする。
Claims (7)
- ガス流路からの加圧ガスを受ける入口(602)と、患者まで加圧ガスを運ぶ第1の出口(604)とを有し、患者までのガス経路に沿って加圧ガスを運ぶ呼吸補助および/または蘇生装置(600)用の圧力調整器(601)であって、前記圧力調整器(601)が:

前記シート部材(611)の位置は使用者が前記マウント(613)に取り付けられた制御部材(622)を手で操作することにより、前記第2の出口(606)内で手動により調整でき、これにより前記弁部材(608)が開放される前記所定の圧力レベルが調整可能となる、圧力調整器(601)。 - 前記制御部材(622)が前記マウント(613)に回転自在に結合されているか、または前記制御部材(622)はオペレーターの指によって手動により調整でき、前記オペレーターは制御部材を回転させて前記所定の圧力レベルを調整する、請求項1に記載の圧力調整器(601)。
- 前記弁部材(608)がスカートまたは少なくとも1つのフラップ(612)を含み、前記弁部材(608)はシャフトにより前記マウントに結合され、前記弁部材が開放される前記所定の圧力レベルはスカートまたはフラップ(612)を前記シート部材(611)に対して相対的に移動させることにより調整される、請求項1または2記載の圧力調整器(601)。
- 前記第2の出口(606)に設けられたフランジを更に備え、このフランジはオペレーターが前記フランジに圧力を付与することができる構造をもつ、請求項1乃至3のいずれか記載の圧力調整器(601)。
- 前記シート部材(611)は加圧ガスの圧力が前記所定の圧力より下がった場合、弁部材(608)の一部が前記シート部材に当接するよう配置されているか、および/または前記シート部材(611)が前記制御部材(622)と係合して制御部材を操作することにより前記シート部材(611)を移動させて前記所定の圧力を調整するか、および/または圧力調整器(601)は前記制御部材(622)を操作することにより前記シート部材(611)を前記加圧ガスの流れと平行する方向に移動させるような構造をもつ、請求項1乃至4のいずれか記載の圧力調整器(601)。
- 前記制御部材(622)は前記シート部材(611)に対して回転方向に結合され、かつ前記シート部材(611)が前記マウント(613)にねじ係合して、前記制御部材(622)を回転させることにより、前記シート部材(611)の調整を行なう、請求項1乃至5のいずれか記載の圧力調整器(601)。
- 前記制御部材(622)は前記第2の出口(606)に取り付けられた時、前記第2の出口(606)から延びるカップ形状をなし、前記カップ形状の制御部材(622)に設けられたオリフィス(634)が加圧ガスを放出するか、および/または、オリフィス(634)はオペレーターの指または親指を配置することにより閉じられるか、および/または圧力調整器(601)は略一定の5〜15リットル/分の呼気終末陽圧(PEEP)を提供する、請求項1乃至6のいずれか記載の圧力調整器(601)。
