Methods for the manufacture of a medical tubing and medical use of a pipeline with a pump for the dosed quantities of a fluid administration benefit over time to a patient, and,The pipe ". The present invention provides a method for manufacturing a medical tubing.The method includes the steps of: (1) providing a material selected from the group consisting of ethylene homopolymers and copolymers of ethylene.In the ethylene copolymers are obtained by copolimerizau00e7u00e3o of ethylene with a comonomer selected from the group consisting of alkyl, lower alkyl olefins, olefin below,Lower alkyl ester of a carboxylic acid and alkene carboxylic acid esters of a lower alkyl, lower and lower alkene having, each, 3 to 18 carbons.Or mixtures thereof; (2) providing an extruder with a matrix of extrusion; (3) extrusar material in the form of a medical tubing; (4) to provide a solution of surface modifier; (5) pre AQUecer solution surface modifier at a temperature within the range of 50 - 80 198 C; and (6) to apply the solution preheated on the tubing, to the extent that it leaves the matrix of extrusion.When the pipe is in a molten state or semi melted.
