First Claim
1. A fluid container comprising:
- a receptacle for retaining a fluid;
at least one conduit in communication with the receptacle; and
the at least one conduit defined, at least in part, by a port assembly,the port assembly including a housing with an opening and a bore therethrough, a slit septum disposed in the opening to control access through the opening, a base joined to the housing and having a membrane attached thereto, a perforator having a first end abutting the slit septum and a second end aligned with the membrane, and a resilient member disposed between the perforator and the base,the perforator having first and second lumens, the first lumen extending between the first and second ends of the perforator and the second lumen extending between a point between the first and second ends and the second end, a seal disposed about the first lumen at the first end of the perforator and a valve associated with the second lumen to limit flow of fluid through the second lumen in the direction of the second end.

Abstract
A port assembly includes a housing with an opening and a bore therethrough, a slit septum disposed in the opening to control access through the opening, a base joined to the housing and having a membrane attached thereto, a perforator having a first end abutting the slit septum and a second end aligned with the membrane, and a resilient member disposed between the perforator and the base. The perforator has first and second lumens, the first lumen extending between the first and second ends of the perforator and the second lumen extending between a point between the first and second ends and the second end. The perforator also has a seal disposed about the first lumen at the first end of the perforator, and a valve associated with the second lumen to limit flow of fluid through the second lumen in the direction of the second end.

18. A port assembly to be used in a conduit of a fluid container, the port assembly comprising:
-
a housing with an opening and a bore therethrough, a slit septum disposed in the bore to control access through the opening, the slit septum including a sleeve having first and second ends and an inwardly-depending ring disposed at the second end of the sleeve, a base joined to the housing and having a membrane attached thereto, a perforator having a first end abutting the slit septum, a second end aligned with the membrane, a passage between the first and second ends, and a bypass disposed at the first end of the perforator to permit fluid to flow between the passage and inbetween the inwardly-depending ring and an outer surface of the perforator; and a resilient member disposed between the perforator and the base.
