Abstract
The present invention provides a method of using a medical tubing with a pump for administering measured amounts of a beneficial fluid over time to a patient comprising the steps of providing a tubing having a first layer selected from the group consisting of ethylene homopolymers and ethylene copolymers, wherein the copolymers of ethylene are an ethylene monomer copolymerized with at least one monomer 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 having from 3 to 18 carbons, the tubing having been exposed to a sterilization dosage of radiation of from about 15 to about 45 kGys; and pumping fluid through the tubing with the pump.
