Description
当該操作者は、カテーテル14を通っての血液の進行を止めるためにカテーテル16をクランプし、通気プラグ22を取り除き、通気プラグ22を輸液セット連結器やルアーアクセス器具又はポート24と類似又は同一のルアー・アクセス・デバイスのようなもう1つの脈管アクセス器具に置き換え、カテーテル16のクランプを解除し、血液をカテーテル14から患者の脈管構造の中に洗い戻して、そしてカテーテル16を再度クランプする。代わりの通気部及び通気手順が切望されおり、図1の後に続く図面を参照して論じられる。
該通気挿入部90は、流体ではなく、空気又は他のガスが通過するのを許容する多孔質の材料を含む、如何なる通気材料から形成されてもよい。通気挿入部90は、先端部88の外面上に置かれ、先端部のハウジング32と器具24に連結されている他の如何なる脈管アクセス器具のハウジングとの間に通気部をもたらす。この方法で、通気挿入部90は、器具24に連結されている脈管アクセス器具を含む脈管外システムのために、液体ではなく空気の通気部として作用するであろう。図10Aに示されるように、図10の10A-10A線に沿ってとられた10A-10A断面は、ハウジング32の外面の通気挿入部90を示している、先端部88の頂部断面図を図解している。
Claims (4)
