Description
図2は、第1実施形態における装着具の使用状況を説明する図である。ここでは、使用者が呼吸用マスク8を装着具14により装着したときの正面図と側面図とが示される。フレキシブルホース4bと連結され鼻孔を覆う呼吸用マスク8の両側部には、装着具14が連結される。装着具14は、長手形状を有し1つの端部が呼吸用マスク8の両側部のいずれかに連結される一対の連結部材であるストラップ10と、ストラップ10の他の端部に連結される一対の固定部材であるプラグ12とを有する。なお、以下の説明では装着時における使用者を基準として、左右、前後、及び上下の各方向を規定する。
図5は、固定部材としてのプラグ12の第1実施例について説明する図である。図5(A)〜(D)は、プラグ12の側面方向からの外観を示す図である。図5(A)に示す例では、プラグ12は外耳道の入口付近に挿入される挿入部12dをさらに有する。挿入部12dは、すくなくともその一部が外耳道の直径と同等かそれよりもやや大きい直径を有する、略円柱形状もしくは略円錐台形状(一点鎖線で図示)に形成される。かかる挿入部12dを設けることで、プラグ12が耳珠内側の窪みに嵌合することに加え、挿入部12dの外壁と外耳道との摩擦力によりプラグ12の脱落がより高い確度で防止される。特に、連結部12bを矢印T2が示す方向に回動させるような外力が連結部12bに作用した場合に、かかる外力に連動してプラグ12は矢印T3が示す方向に回動しようとする。このとき挿入部12dを有することでその摩擦力及び抗力によってかかる回動に対抗でき、挿入部12dを設けない場合より高い確度でプラグ12の脱落を防止できる。
図7は、固定部材としてのプラグ12の第2実施例を説明する図である。図7(A)には、右側のプラグ12を例としてその平面図が示され、図7(B)には同側面図が示される。ここでは、理解を容易にするために、連結部12bの図示は省略される。また、図8は、第2実施例の使用状況を説明する図である。図8には、右側の耳を例として、耳の各部名称と、プラグ12が嵌め込まれた状態が点線で示される。
図11は、固定部材としてのプラグ12の第3実施例について説明する図である。第3実施例は、プラグ12の脱落をより高い確度で防止するうえでさらに好ましい実施例である。第3実施例は単独で、または上述した第1、第2実施例のいずれかと同時に実施可能である。
図13は、装着具14の第2実施形態について説明する図である。この装着具14は、ストラップ10の呼吸用マスク8に連結される端部と反対側の端部に設けられ、使用者の耳の位置で固定される。図13は、例として右耳用の装着具14を示し、紙面の右方が前方、紙面の左方が後方に対応する。
第3実施形態では、装着具14は、その長手方向に沿って設けられる支持部材を有する。
第4実施形態では、装着具14は、その長手方向に沿って設けられる支持部材を有する。この支持部材は、呼吸用マスク8に固定される第1の板状部材と、前記連結部材に固定される第2の板状部材とを有し、前記第1、第2の板状部材は、回動可能に構成される。第4実施形態は単独で、あるいは第1、第2実施形態、あるいは他の装着具のいずれか一つ以上と同時に実施することが可能である。また、第4実施形態を実施する際の呼吸用マスクは、鼻孔部周辺のみを覆う呼吸用マスク8でもよいし、鼻孔部と口とを覆う呼吸用マスクでもよい。
まず、図23を用いて呼吸用マスク8の概略構成を説明する。呼吸用マスク8は、その外郭を形成するとともにフレキシブルホース4bと連結されるフレーム20と、このフレーム20と組み合わせて用いられ、使用者の鼻孔周辺部に接触してこれを覆うクッション30とを有する。
呼吸用マスクの第2実施形態では、フレーム20にL字管28を一体成型して設けることで呼吸用マスク8の部品点数とコストを低減させることができる。そして、フレーム20とクッション30とが嵌合する部分、つまり吸排気ポート22、32と、嵌合溝26、嵌合条38とを180度回転対称の形状に形成する。それとともに、フレーム20とストラップ10に設けられるパネル16との嵌合部27を180度回転対称の形状に形成する。そうすることで、ユーザの好みに応じてL字管28の先端部の向きを左右どちらに向けても呼吸用マスク8を構成でき、装着具14により装着することができる。これにより、使用者が横臥したときにフレキシブルホース4bを体で押しつぶすおそれが少ない方向に予めフレキシブルホース4bを向けて呼吸用マスク8を装着できる。よって、フレキシブルホース4bを押しつぶして呼吸用気体の供給が阻害されることを防止できる。
