Abstract
A coextruded tri-layered medical-surgical tubing for the administration of common medicines such as insulin and nitroglycerin solutions is disclosed. Improved flexibility and uniformity and increased peel strength are obtained by interposing a layer of an ethylene-vinyl acetate copolymer between an outer layer of polyvinyl chloride and a core layer of low-density polyethylene. The composite tubing exhibits excellent fluid flow characteristics and is readily employed in the transportation of intravenous fluids and the like without absorbtion or contamination difficulties.
