Description
本出願は、オーストラリア仮特許出願第2008906390号(2008年12月10日出願)、オーストラリア仮特許出願第2009900327号(2009年1月29日出願)、オーストラリア仮特許出願第2009902731号(2009年6月12日出願)、及びオーストラリア仮特許出願第2009904236号(2009年9月4日出願)の利益を主張し、参照によってそれぞれがその全体を本明細書に組み込まれる。
nsible)」を有する構造とは、呼吸マスクの使用において通常遭遇する力を受けた際に、約5%未満、より好ましくは約3%未満の伸長しか有しないであろう構造を意味する。
柔軟な」(floppy)構造とは対照的である。
図に、本発明の別の実施形態によるヘッドギアを示す。図示された実施形態において、ヘッドギアはマスクに取り外し可能に取り付けられるように構成され、これによりマスクを、患者の顔における望ましい位置に保持及び維持する。ヘッドギアは、特殊な種類のマスクと共に用いられるように図示される場合があるが、それぞれのヘッドギアは他の適切なマスクと共に用いられるように構成することができる、ということが理解されるべきである。即ち、それらマスクは単なる例に過ぎず、それぞれのヘッドギア実施形態は、例えばフルフェイスマスク、鼻マスク、口マスク、ノズル又はパフ、鼻カニューレ等のような任意の適切なマスクとともに、任意の適切な構成(例えば前額部の支持の有無によらず)に用いられるように構成することができる。
好ましくは、それぞれのヘッドギアは2つの側部を、側部に接続する後部と共に含む。側部は、従来のヘッドギアと両立するようにした(例えば従来のヘッドギアを後付けするようにした)マスクとの4点接続を提供する。しかしながらヘッドギアは、例えばマスクとの2点接続、マスクとの3点接続、マスクとの5点接続のような、より多いか、又はより少ない接続点を提供するように構成することができる、ということが理解されるべきである。
ヘッドギアは、剛性又は半剛性を有する材料によって構成された1つ以上のリジダイザを含んでもよく、このリジダイザは剛性をヘッドギアに加え、使用中にヘッドギアを所定位置に固定するように構成される。リジダイザは、リジダイザの長さに沿って屈曲又は変形可能であってもよいが、リジダイザの長さ方向におけるヘッドギアの伸張に抵抗するか、又は伸張を妨げることができる。リジダイザは実質的に非伸張性であってもよい。リジダイザは弾力性があってもよい。本発明によるリジダイザは好ましくは1つ以上の以下の特徴を有する。
・形状を保持する
・ヘッドギアが、封止力ベクトルの向きを眼の周囲又は耳の周囲のような湾曲部に沿っ て変えることを可能にする、
・可撓性を有する、及び/又は
・特定の面において、所定の形状を維持するための構造を提供する
1つ以上のリジダイザは、例えば快適性、美観、有用性等のために、患者の頭部の別の部位と係合するように構成し、位置決めすることができる。
図1〜図3に、リジダイザを含むヘッドギアを図示する。このリジダイザは、患者の頭頂骨において、いずれの側にも略垂直な方向で適合するよう構成され、これによりヘッドギアを所定位置に固定する。
1つの本体62から患者の前額部を横切って患者の頭部の反対側において対向する本体62まで延在するように構成された単一の部品とすることができる。
図4〜図5に、患者の頭頂骨のいずれの側(即ち略垂直方向において)にも適合し、それによってヘッドギアを患者の後頭部における所定位置に固定し、且つ患者の頭部の前面と患者の頬骨とに延在するように構成されたリジダイザを含む、ヘッドギアを図示する。
図6〜図11に、略完全円/楕円形状(例えば、後頭部において切り離された、調節性のための円弧を有することができる形状)を形成するよう構成され、これによりヘッドギアを患者の後頭部における所定位置に固定するリジダイザを含むヘッドギアを図示する。図示されるように、リジダイザは患者の頭頂骨及び後頭骨に沿って延在する。
ザ7560のための、別の構成を示す。リジダイザは略電球形状に形成されてもよく、この形状には2つの略円形部位又は略湾曲部位が存在し、即ち使用の際に患者の頭部のほぼ頭頂骨領域に係合するように構成された上部部位7562と、使用の際に患者の頭部のほぼ後頭骨領域に係合するように構成された下部部位7564とを備えている。上部ストラップ7512は、マスク上部部位との係合のために上部部位7562に設けられ、下部ストラップ7514は、マスク下部部位との係合のために下部部位7564に設けられる。
1つ以上のリジダイザは、マスク及び/又は異なる物と、異なる構成において連結することができる。
ップへオーバーモールドされるか、又は超音波溶着されたもの)を設けてもよい。図13に示すように、スタッド665及び穴663はスナップフィット(snap fit)構成を設けるように構成される。下部ストラップ630の反対側の端部は、マスクに取り付けるために、ベルクロ(登録商標)タブを含んでもよい。
また図18に、弓状部又は屈曲部4000を有しうるリジダイザ3001を備えた、密閉された第一ストラップ3010を示す。屈曲部4000は、リジダイザ3001の限定された部位に設けられてもよく、これによりこの部位においてリジダイザを容易に曲げるか、又は蝶番状に折り曲げることが可能となる。このことは、より広い範囲の患者の頭部サイズに適合するために有益な場合がある。図18に示されるように屈曲部4000は、リジダイザの下部部位を患者の耳に向かって外側へ曲げるか、又は患者の頭部の中心に向かって内側へ曲げるかを可能にするように位置決めすることができる。屈曲部4000は脆弱部位であってもよく、これによりリジダイザ3001において同様の可撓性を達成することができる。例えば、屈曲部4000はリジダイザ3001における湾曲部位、横断面が薄化された部位、幅が狭くされた部位であってもよい。この屈曲部位は、例えばマスクシステムへの直接接続のための上部及び下部ヘッドギアストラップのような、ヘッドギアの異なる部位のように、張力をかけることはできない。
実施形態において、リジダイザ及びヘッドギアストラップの調節は、フックアンドループ(hook and loop)材料(例えばベルクロ(登録商標)、弾性体、押圧スタッド、等)によって提供することができる。
リジダイザは、2つ以上の材料を有する複合構造(より軟質であり、患者に接触する材料によって構成された被覆を有する、剛性又は半剛性を有する材料)を有してもよく、別の布地又はポリマー材料(三次元織物、編物、不織布、積層体)によって構成されてもよく、且つ別の方法において製造することができる。
好ましくは、ヘッドギアの製造方法は、生産量を最大化し材料の廃棄を削減することによってコストを低減し得る。例えばコンポーネントは、コンポーネントをバルク材料において接近してネスト式に配置させることが可能であるように形作られてもよく、これにより、個別のコンポーネントにダイカットする際に、廃材が減少し、従ってコストが低減される。
