The luer adapter of this invention includes a barbed portion having a generally cylindrical distal portion, a generally conical portion, a generally cylindrical portion and a generally outwardly tapered proximal portion. The shape of the barb is substantially the same as the shape of the lumen at the proximal end of a catheter but is slightly larger radially and slightly shorter axially than the proximal portion of the lumen. This ensures that when the barb is inserted into the proximal portion of the lumen the luer adapter is positively locked to the catheter.

Le raccord Luer de la présente invention comprend une partie cannelée ayant généralement une partie distale cylindrique, une partie généralement conique, une partie généralement cylindrique et une partie proximale généralement conique vers l'extérieur. La forme de la cannelure est essentiellement la même que celle de la lumière à l'extrémité proximale d'un cathéter mais elle est légèrement plus large radialement et légèrement plus courte dans l'axe que la partie proximale de la lumière. Cela permet d'assurer que, lorsque la cannelure est insérée dans la partie proximale de la lumière, le raccord Luer est solidement fixé au cathéter.
