Medical pump tubing having a first layer of ethylene copolymerized with alkyl olefins or alkyl and alkene esters of carboxylic acid

摘要

A medical tubing for use with a pump for administering measured amounts of a beneficial fluid over time to a patient comprises a sidewall of the tubing having a first layer of either ethylene homopolymers or ethylene copolymers wherein the tubing has been exposed to a sterilization dosage of radiation of from 15 to 45 kGys. The ethylene copolymers are ethylene co polymerized with a monomer being alkyl olefins, alkyl esters of a carboxylic acid and alkene esters of a carboxylic acid. The sidewall has a melt flow index of less than 5.0 g/10 minutes.
