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.

Abstract: An improved port protector (10) for removably sealing an opening located at an end of a tubular member. The port protector (10) comprises a cap portion (12) including a top (18) and side walls (17, 19) and defining an interior for receiving the end of the tubular member and removably sealing the opening of the tubular member. The cap portion (19) at least is constructed from a thermoplastic elastomer and the top (18) has a sufficiently thin cross-sectional thickness (a) to allow steam to pass through the top (18) into the opening of the tubular member during steam sterilization. Additionally, the port protector (10) includes means (14) extending from the cap portion (12) for allowing removal of the cap (12) from the tubular member. Additionnaly, the present invention provides an improved container assembly (30).
