Description
本発明と関連して使用するポート本体が、そこ(ポート本体を通って意図的に提供される通路の外側)を通る液体又は気体の通過を制限又は効果的に防止する流体バリアを提供する材料で製造されることが好ましい場合がある。好ましくは、ポート本体に使用される材料は、身体部位に適合し、かつ接着するのを補助するために、比較的弾力性又は可撓性であり得る。いくつかの潜在的に適切な材料の例としては、例えば、プラスチック化されたPVC、ポリウレタン、シリコーン、ブロックコポリマーエラストマー(例えば、KRATON)、ポリオレフィン(メタロセンポリオレフィンを含む)、ポリアミド(例えば、PEBAX)、エラストマーポリエステル(HYTRELエラストマーを含む)等が挙げられる。エチレン−プロピレン−ジエンモノマー(EPDM)、ブチルゴム、ニトリルゴム、天然ゴム、ネオプレン等の熱硬化性エラストマーも適切であり得る。
本発明の医療用手当て用品は、好ましく、液体及び少なくともいくらかの気体の通路にバリアを提供する、適合裏材と併せて、有用である。典型的な裏材は、高分子フィルム及び他の同様の裏材を含み得る。好ましい好適な裏材は、半透明又は透明の高分子フィルムである。
いくつかの例では、本発明の医療用手当て用品で使用する裏材は、剥離ライナーが裏材から除去されるとき、裏材が患者の皮膚への包帯の円滑で無菌の適用を阻害して、それ自体を褶曲し、かつそれに接着する傾向があり得るような非常に可撓性及び柔軟であり得る。
好ましくは、本発明の医療用手当て用品及びポート本体に使用され得る感圧接着剤は、米国特許第RE 24,906号に記載されるアクリル酸コポリマー、具体的には、96:4のイソオクチルアクリレート:親油性コポリマー等の、典型的に皮膚に適用される接着剤を含み得る。別の例は、米国特許第4,737,410号(実施例31)に記載するとおり、70:15:15のイソオクチルアクリレート:エチレンオキシドアクリレート:アクリル酸ターポリマーを含み得る。他の潜在的に有用な接着剤は、米国特許第3,389,827号、同第4,112,213号、同第4,310,509号、及び同第4,323,557号に記載されている。米国特許第4,310,509号及び同第4,323,557号に記載されているように、薬剤又は抗微生物剤が接着剤に包含されることも想起される。
本発明の医療用手当て用品の使用に適切であり得る剥離ライナーは、スーパーカレンダー仕上げのクラフト紙、グラシン紙、ポリエチレン、ポリプロピレン、ポリエステル、又は任意のこれらの材料の複合物からなる可能性がある。好ましくは、ライナーは、炭化水素、フッ素性化学物質、シリコーン、又はこれらの組み合わせ等の離型剤で被覆される。例えば、米国特許第4,472,480号は、低表面エネルギーペルフルオロ化合物ライナーを記載する。好ましくは、ライナーは、紙、ポリオレフィンフィルム、ポリオレフィン被覆紙、又はシリコーン剥離材で被覆されたポリエステルフィルムの形状であり得る。市販のシリコーン被覆の剥離ライナーの例は、ポリオレフィン被覆紙上のシリコーン剥離である、POLY SLIK(商標)、フィルム上のシリコーン剥離である、FL2000(商標)、及びスーパーカレンダー仕上げのクラフト紙上のシリコーン剥離である、STICK−NOT(商標)、(全ては、Loparex社(Willowbrook,Ill.)から入手可能)、Akrosil社(Menasha,Wis.))のシリコーン被覆のスーパーカレンダー仕上げのクラフト紙、及びHuhtamaki Florchheim社(Florchheim,Germany)のシリコーン剥離フィルムである。別の潜在的なライナーは、Huhtamaki社から入手可能なシリコーン被覆(1630)低密度ポリエチレンである。
