Abstract: 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.

Abstract: A flexible fluid junction that links three or more fluid ducts is provided. The junction includes a pair of flexible webs with at least three tubes or fluid ducts disposed between the flexible webs. The outer periphery of the webs is sealed together and around the tubes to define a chamber. An end of each tube terminates inside the chamber so that fluid may flow from each tube through the chamber. Still further, a method of manufacturing a flexible fluid junction and a method of using a flexible fluid junction are also provided.

Abstract: A system, a method and administration lines are provided for self-priming of a solution delivery system. The administration lines are arranged such that resultant forces acting on the lines create different forces applied on each lumen resulting in solution flowing in one of the lumen undergoing a higher isostatic pressure. The lumens forming the administration line may be formed from concentric tubings or formed from separate tubings extending varied lengths into the solution container. As a result, automatic priming of the administration line and the solution delivery system is provided.
