Patent ID: 6994315

Claim:
An injection port assembly for coupling to and uncoupling from a first fluid pathway of a first connector and for coupling to a device provided with a second connector so as to provide a fluid connection between the first and second connectors, said injection port assembly comprising: a first mating structure adapted to mate with the first connector and a second mating structure coupled to said first mating structure and adapted to mate with the second connector, a resilient barrier located between said first and second mating structures and movable from a first position in which fluid flow between said first mating structure and said second mating structure is blocked to a second position in which fluid flow between said first mating structure and said second mating structure is permitted, said resilient barrier includes a boot valve and a septum, and said septum has a lower frustrum and an upper frustrum of different diameter defining a shoulder, said upper frustrum having a continuous convex surface.
