近位側構造と遠位側構造との間に配置された疎水性および非吸水性を有するインサート構造とを有し、前記近位側構造は液体の効果の下で膨張できる物質からなり、該物質の膨潤により近位側構造と遠位側構造との間の距離が減少されて、液体は、近位側構造からインサート構造を通って遠位側構造に通ることができる。
製造中に、インサート22は、界面層23がインサート構造40に組付けられる前に、界面層23上の所定位置に置かれる。
試験は、23℃および33%および35%の湿度(hygrometry)で行われた。

・インサート22:Novathin(登録商標)J000950DTNBのペレット。ペレットの厚さは約1mm
・移送層32:セルロース(55%)およびポリエステル(45%)(Orsa社からのJettex(登録商標)1205C
・リザーバ形成層31:製造業者AMS社の商標MCF03を有する厚さ4.5mmの親水性PU発泡体
好ましくは、下方層401の開口501は5〜25mmの間、例えば8mmの直径(最大寸法)を有し、一方、上方層402の開口502は1〜10mmの間、例えば3mmの直径(最大寸法)を有する。
