ABSTRACT:
The septum includes a unit with two fill chamber sections, each having a corresponding needle penetrable seal member for sealing the respective fill chamber sections. The seal members are oppositely disposed and thereby permit access to a corresponding fill chamber section at two different orientations of the septum. Thus, when the septum has flipped over from its original position, one of the fill chamber sections continues to remain accessible for fluid infusion and/or fluid withdrawal. A needle stop portion in the unit which forms a partition between the fill chamber sections prevents a needle that has entered one of the fill chamber sections from passing out of the other fill chamber section. In several embodiments of the invention, the partitioning needle stop section is moveable and in other embodiments of the invention, the partitioning needle stop section is immoveable. Thus there is provision for expanding and contracting the fill chamber sections in some of the embodiments of the invention. In all embodiments of the invention the fill chamber sections are communicable.
