Description
本文献に使用される用語は、以下に記載する意味を有する:
「キャリッジ」は、ストラップおよびマスク本体に取り付けられ、使用時に着用者の顔面上でマスク本体を支持することを助ける構造部品(および/又は、部品の組み合わせ)を意味し;
「中心部分」は、マスク本体の鼻部分、顎部分、および頬部分の略中心に位置するマスク本体の部分を意味し;
「頬部分」は、マスク本体が着用されているとき、着用者の顔面の頬領域を覆って配置され、頬領域と接触していてもよいマスク本体の部分を意味し;
「顎部分」は、マスク本体が着用されているとき、着用者の顔面の顎領域を覆って配置され、顎領域と接触していてもよいマスク本体の部分を意味し;
「弾性限界」は、材料が受け、且つ、応力から解放されたとき、まだその元の形態に戻ることができる歪の限界を意味し;
「外部気体空間」は、人に着用されているときマスク本体を取り囲み、呼気がマスクの内部気体空間を出た後、それを最終的に受け入れる周囲大気気体空間を意味し、
「曲げ弾性率」は、ASTM790−03、「無補強および補強プラスチックおよび電気絶縁材料の曲げ特性の標準試験方法(Standard Test Methods for Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials)」に準拠して決定される曲げ弾性率を意味し、
「ハーネス」は、呼吸マスクの一部を形成し、人の顔面上でマスクを支持する役割をするデバイスを意味し、
「一体」は、後で一緒に接合される2つ以上の別々に製造された部品ではなく、同時に1個のものとして製造されていることを意味し、
「内部気体空間」は、マスクが着用されているとき、マスク本体と人の顔面との間に存在する空間を意味し、
「マスク本体」は、人の鼻および口を覆ってフィットするように形成され、外部気体空間から分離した内部気体空間を画定することを助ける構造部材を意味し、
「非エラストマー」は、弾性限界における伸びが約10%未満である材料を意味し、
「鼻部分」は、マスクが着用されているとき、人の鼻の鼻梁を覆って延びるマスク本体の部分を意味し、
「呼吸用マスク」は、人の顔面に着用され、その人に濾過された清浄な空気を供給するように構成されているデバイスを意味し、
「剛性インサート」は、着用者の顔面と接触し、着用者の顔面に概ね適合する追従性のより大きい部分に接合されるのと同時に、フィルタカートリッジおよび排気弁などの流体連通構成要素を取り付けるのに十分な構造を提供するために、呼吸用マスクに使用されてきた比較的堅い構造部材を指し、
「ストラップ」は、曲げ易い材料の細長く狭い細片又はコードを意味する。
着用時にフェースマスクに掛かる載荷力(loading forces)を模倣する荷重をマスクに加えることにより、マスク本体の撓みを決定した。本体が外向きのマスク外部上で支持されている時の、鼻部分および顎部分に加えられる荷重に応答するマスク本体の横方向の撓みを測定した。荷重を合計の力としてNで記録し、撓みをmmで記録した。頬部分の外周縁部の2点間のマスク本体の顔面にフィットする開口部に対応する、本体における位置でマスク本体の撓み測定を行った。鼻部分と顎部分によって画定される軸に沿ってマスク本体に荷重を加えた。
Claims (3)
- (a)剛性インサートがなく、非エラストマーであり、人の鼻および口を覆ってフィットするように構成されたマスク本体であって、鼻部分、顎部分、第1および第2の頬部分、並びに、前記鼻部分から前記顎部分まで延びる軸を有するマスク本体であり、マスク本体が静止状態に保持され、前記鼻部分と顎部分に力が及ぼされると、前記第1および第2の頬部分が前記軸を中心として互いの方に動くことができるように、変形するように構成されているマスク本体、および
(b)着用者の顔面上で前記マスクを支持することを助けるハーネス、
を備える呼吸用マスク。 - (c)前記マスク本体に取り付けられる1つ以上のフィルタカートリッジ、
を更に備える、請求項1に記載の呼吸用マスク。 - 前記マスク本体の中心部分に位置する排気弁を更に備え、前記ハーネスがキャリッジおよび少なくとも1つのストラップを備え、前記キャリッジが排気弁を覆い、前記マスク本体の中心部分に固定されている、請求項2に記載の呼吸用マスク。
