Description
a)発熱条件、及び/又は
b)患者の近く、すなわち、亜酸化窒素の分解のための装置に患者が直接接続された状態、
で分解が行われる、移動可能な装置に対する需要がある。
図2から明らかなように、図1を参照して上述したものと本質的に同じタイプの試験装置1を使用した。試験装置1には、さらに、亜酸化窒素濃度を測定するための0~100000ppmの測定範囲を有するIRタイプのガス分析器14と、当該試験装置に供給される亜酸化窒素の量を決定するための亜酸化窒素用のマスフローコントローラー15とを設けた。亜酸化窒素の質量流量は、0.5~100g/minであることができる。
空気ガス流量:2.6Nm3/h
N2Oの供給量:7g/min
反応器温度:400~450℃
ガス濃度N2O:85000ppm
実行時間:10~30分間
以下は、さまざまな実験の結果である。実験1は、活性炭手段の後への亜酸化窒素ガスの注入に関するものである。これは、亜酸化窒素ガスが活性炭手段を通過しないことを意味する。実験2は、活性炭手段の前への亜酸化窒素ガスの注入に関するものである。後者の場合、亜酸化窒素ガスは、触媒に供給される前に活性炭手段によって最初に吸収される。すなわち、活性炭手段は吸着/脱着手段4として機能する。
活性炭手段の利点は、亜酸化窒素の濃度が、システム内で徐々に上昇し、活性炭手段なしの場合よりも大幅に低いことである。これは、反応器内の温度上昇の低減をもたらす。
本発明に関連する発明の実施態様の一部を以下に示す。
[態様1]
患者からの呼気に由来するガス流中の亜酸化窒素の触媒的分解のための装置(1)であって、
a)前記呼気用のガス入口(3)を備えた入口設備(2)、

これらの装置の間の、c)亜酸化窒素のN 2 及びO 2 への分解を促進する触媒材料を含むスルーフロー分解室(9)、
を含み、
前記分解室(9)に供給される亜酸化窒素の濃度の変動を平準化するために少なくとも1つの亜酸化窒素吸着/脱着手段(4)が前記入口設備(2)に設けられていることを特徴とする、装置。
