The present invention provides a method for fabricating a medical tubing. The method includes the steps of: (1) providing a material selected from the group consisting of ethylene homopolymers and ethylene copolymers, wherein the ethylene copolymer are obtained by copolymerizing ethylene with a comonomer selected from the group consisting of lower alkyl olefins, lower alkyl olefins, lower alkyl esters of a carboxylic acid and lower alkene esters of a carboxylic acid, the lower alkyl and lower alkene each have from 3-18 carbons, or blends thereof; (2) providing an extruder with an extrusion die; (3) extruding the material into a medical tubing; (4) providing a surface modifier solution; (5) preheating the surface modifier solution to a temperature within the range of 50-80 ~C; and (6) applying the preheated solution onto the tubing as it exits the extrusion die when the tubing is in a molten state or a semi- molten state.

L'invention concerne un procédé permettant de fabriquer une tubulure médicale. Ce procédé consiste : (1) à prendre un métal choisi dans le groupe constitué d'homopolymères d'éthylène et de copolymères d'éthylène, dans lesquels l'éthylène joint au co-monomère choisi dans le groupe constitué d'oléfines d'alkyle inférieur, d'alkyle inférieur et d'alcène inférieur contiennent chacune entre 3 et 18 atomes de carbone, ou constitué de mélanges de ces éléments; (2) à produire un extrudeur au moyen d'une extrudeuse; (3) à extruder la matière sous forme d'une tubulure médicale; (4) à utiliser une solution de modification de surface; (5) à préchauffer cette solution de modification de surface jusqu'à ce qu'elle atteigne une température comprise entre 50 et 80 ·C, enfin (6) à appliquer la solution préchauffée sur la tubulure, à mesure qu'elle sort de l'extrudeuse lorsque la tubulure est dans un état fondu ou semi-fondu.
