METHOD OF SURFACE MODIFYING A MEDICAL TUBING |
摘要 |
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 copolymers are obtained by copolymerizing ethylene with a comonomer selected from the group consisting of 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 at it exits the extrusion die when the tubing is in a molten state or a semi-molten state. |
