Description
− 小さく、保存又は運搬が容易な加湿器
− 誂える(プロファイルされる)、又は使用者によって設定することができ、使用者の状況、必要、又は快適性に対する希望に合う装置
− 非効率的な“パスオーバ”の(加熱機能のない)加湿器と、フル機能の加熱機能を有し、最も乾燥した気道の病気を治療するための加湿器との間のギャップを橋渡しするプロファイル加湿器
− 患者が寒い部屋が結露の増加の原因となると気づくだけで、患者自身が装置を高湿度の設定に調整したのであるから“レインアウト”又は結露に対して潜在的にほとんど不平は無いこと。
− 患者の治療のコントロール、修正及び微調整の能力
− 必要のないときに、湿度の供給を最小化することによる、水の使用及び必要とされる保存容積の削減と、それによる装置の大きさの削減。
− 快適さに対する期待値を満足するために設計面から妥協できる余地がほとんどない、OSA市場のための技術者に対する、大きさの制限の軽減。
− 一方では流量生成器は既にその大きさを削減され、他方で、加湿器は次世代の流量生成器より大きくなくとも、ほぼ同じ大きさであること。
このコンセプトによって、使用者は潜在的により軽く、移動しやすいより小型の寸法であるという感覚を持つ。
