Abstract
【解決手段】減圧治療システムは、第1の側面及び第2の側面を有するバッキング基板141と、バッキング基板の第1の側面に配置された複数の突起部とを有する分配マニホルド115を具える。突起部の各々は実質上円形の断面形状を有し、かつ、約0.1ないし2.0ミリメートルの間の直径を有し、バッキング基板は第1の側面と、第1の側面の逆側の第2の側面との間で流体接続を可能にするように形成される複数の開口部を有する。減圧供給源は、開口部を通って、突起部間で、及び組織部位に対して減圧を伝えるべくバッキング基板の開口部に流体接続される。
【選択図】図4
Description
図6及び7によると、試験され、かつ気泡質発泡体と同様の成長誘発速度を証明した1の特定の分配マニホルド215は、50.8ミリメートル(2インチ)の直径のバッキング基板241を利用する。バッキング基板は断面形状においては一般的に円形であり、かつ、突起部がバッキング基板241と接触するベース部から内側にテーパリングされた複数の突起部251を具える。複数の開口部271はバッキング基板241に提供されて、突起部251間の分配チャネル261で流体接続を可能にする。開口部271は突起部251の行及び列の間に配置される行及び列に配列される。このパターンにおける開口部271の配置は、1の開口部271が矩形パターンに配置される各4の隣接する突起部251間の中央に置かれて生じる(図6を参照)。
図8によると、バッキング基板341中に配列された複数の柱状のボイド351を有する、例示的な分配マニホルド315の図示された写真の複製が提供される。バッキング基板341は約1.5mmの厚さであり、各ボイド351の幅(直径)は約0.35mmである。ボイド351はバッキング基板341を通って延在するため、各ボイド351の高さは約1.5mmである。ボイド351間の横方向の中心から中心までの間隔は約0.75mmである。ボイドの幅に対する高さの比率は約4.3:1であり、幅に対する間隔の比率は約2.1:1である。
