Abstract
【解決手段】呼吸補助器械は、好ましくは、ガス供給及び加湿装置である。クリーニング方法は、特にガス供給及び加湿装置内に存在する内部エルボ導管を消毒するのに必要な訓練が最小限であるように自動化された消毒方法である。したがって、ガス供給及び加湿装置を取り外す必要は無く、したがって、ガス供給及び加湿装置の内部部品の不注意による損傷が回避される。本発明は又、加熱呼吸導管及び患者インターフェイスを消毒する方法を提供する。
【選択図】図3
Description
ハウジングを有し、
ハウジング内に設けられたガス供給手段を有し、
ハウジングに設けられていて、ガス供給手段と流体連絡関係にあり、ガスを加湿器に供給するために加湿器の入口と流体連絡関係をなすようになったガス出口を有し、
加湿器に設けられた出口を有し、
ハウジングに設けられた患者側出口を有し、
ハウジングに設けられていて、加湿ガスを加湿器から受け入れて加湿ガスを患者側出口に送るために加湿器出口と流体連絡関係をなすようになったガス戻り部を有し、患者側出口は、加湿ガスを患者に送り出す呼吸導管と流体連絡状態にあり又はこの呼吸導管と流体連絡関係をなすようになっており、
発熱体を備えていて、ガス出口と患者側出口を連結するようになった加熱型ガス導管を有することを特徴とする呼吸補助器械である。
発熱体を備えた加熱型ガス導管をガス供給手段の出口と患者への出口との間に連結するステップを有し、
ガス供給手段は、所定期間にわたり、所定流量のガスを消毒導管に送り、

本発明は、呼吸補助器械であって、この器械内に存在する内部導管をクリーニングする便利且つ有効な方法を実施する呼吸補助器械を提供する。図1に示すように、ガスの流れは、ガス供給手段又は流れ駆動装置(例えば、ブロワ、ファン又は圧縮機)、加湿チャンバ、加熱送り出し回路及び患者インターフェイスを順番に通る。
ガスは、患者インターフェイス2を経て患者に送られる。本発明の装置に用いられる患者インターフェイスは、フルフェースマスク、鼻マスク、鼻カニューレ、経口マウスピース又は気管切開連結部であるのが良いが、以下の説明及び図面は、鼻カニューレの使用を開示している。
ガス供給及び加湿装置4の部分組立て分解図が、図2に示されている。装置4は、ハウジング10に設けられたガス戻り部である入口端部13及びハウジング4の患者側出口である出口端部8を備えたエルボ型の連結導管12を有する。導管12は、加湿チャンバ5から加湿ガスを受け入れるために設けられており、したがって、入口端部13は、加湿チャンバの出口15に連結されている。加湿ガスは、導管の出口端部8から、患者への送り出しのための呼吸導管3(図1参照)内に差し向けられる。エルボ型連結導管12は、ハウジング4内の定位置に永続的に固定されることが好ましい。
本発明のブロワ形加湿装置4の第2の形態では、吸息導管3及び(又は)患者インターフェイス2を消毒する方法が開示される。
