Abstract:
1. A valve comprising a body having first and second open ends and a passageway for fluid between the ends, the first end including a coupling means for sealingly connecting the body about an opening of an external device and a first seal formed with the coupling means closing the open area of the first end, which in use is placeable in register with the opening of the external device, the valve further including a seal displacement means movable within the body so as to displace the first seal permitting fluid to pass along the passageway between the ends, the coupling means and the first seal presenting an external sterilisable mating surface for sealingly mating with a mating surface about the opening in the external device, and an actuation means for moving the displacement means in a first actuation between a ready state in which the first seal is intact and the valve is closed and an open state in which the first seal is separated from the coupling means and moved with the displacement means away from the mating surface so that the valve is open for passage of fluid, the actuation means being engaged with the displacement means via a connecting means and with the body, the connecting means enabling the displacement means to move linearly and non-rotationally along a straight path within the body without side deflection from said straight path; and wherein the displacement means includes a first plastically deformable portion encircling an outer surface of a member of the displacement means and the coupling means includes a second plastically deformable portion encircling its open area which becomes exposed when the first seal is separated therefrom, the displacement means being movable in a second subsequent actuation to bring the first and second plastically deformable portions into engagement so as to form a second seal between said first and second portions, the displacement means comprising a face continuous with the first portion so that the second seal and the face close the fluid passage.
