Description
別の方法は、針アセンブリをバレルの細長い先端に取付けるステップを含んでいる。針アセンブリは、基端部、末端部及びそれを貫通する内腔(a lumen)を有するカニューレ及び空所を含む開口基端部と内腔が空所と流体連通状態になるようにカニューレの基端部に取り付けられている末端部を有するハブを含んでいる。針アセンブリのバレルへの取り付けは、ハブの空所と細長い先端との間の摩擦係合による。この別の方法は、基端部、末端部及びそこを貫通する通路を有するカテーテル及びカテーテルに接続され、カテーテルの通路と流体連通状態にある内部空洞を有するハウジングとともに使用される。ハウジングは、内部空洞との流体連通を許容する隔膜をさらに含んでいる。流体連通は、カニューレの内腔がハウジングの内部空洞と流体連通状態になるように、隔膜を貫通してカニューレの末端部を強制的に押し込むことにより確立される。また、カニューレは、ハブを使用することなく針先端に永久的に取り付けられてもよい。
Claims (6)
- 流体を貯留する室を画定する内面、開口基端部及びそこから末端方向に延び、そこを貫通する通路を有し、前記室と流体連通状態にある細長い先端を有する末端壁を含む末端部を有するバレルであって、前記内面が、前記バレルの末端部において接触領域をさらに含んでいるバレルと、
