A conduit (10) of relatively tough biocompatible material enclosing a longitudinally extending fluid flow lumen (90) has a proximal end configured as a catheter coupling hub (26). The conduit (10) is encircled at the distal end (46) of the catheter coupling hub (26) by a stabilization sleeve (16) made of a contrastingly resilient, soft material suitable for skin contact applications. A pair of stabilization wings (34) extend laterally from the stabilization sleeve (16) at an attachment location (60) separated by a strain relief region (66) from the portion of the stabilization sleeve (16) in which the catheter coupling hub (26) is received. The stabilization sleeve (16) is attached to the conduit (10) at the coupling hub (26) only. The portion of the conduit (10) distal of and adjacent to the catheter coupling hub (26) extends slidably through the stabilization sleeve (16), affording strain relief to the conduit (10).

L'invention concerne un conduit (10) de matériau biocompatible relativement résistant qui entoure une lumière d'écoulement de fluide étendue longitudinalement (90), dont l'extrémité proximale est conçue comme un embout de couplage de cathéter (26). Le conduit (10) est encerclé à l'extrémité distale (46) de l'embout (26) par un manchon de stabilisation (16) en matériau qui, par contraste, est flexible et souple, convenant aux applications de contact avec la peau. Une paire d'ailes de stabilisation (34) s'étend latéralement depuis ledit manchon (16) en un point de rattachement (60) séparé par une zone anti-tirage (66) de la partie du manchon (16) dans laquelle l'embout de couplage du cathéter (26) est reçue. Le manchon en question (16) est relié au conduit (10) uniquement au niveau de l'embout de couplage (26). La partie du conduit (10) distale par rapport à l'embout (26) et adjacente à celui-ci s'étend coulissante dans le manchon considéré (16), ce qui a un effet anti-tirage sur le conduit (10).
