Abstract:
1. A method of intravenously administering parenteral and other fluids to a patient comprising the steps of: providing a split septum unit including— a resilient septum body, wherein the body presents opposite proximal and distal faces and a slit extending therebetween to receive a cannula, said septum body including a terminal proximal face, an annular exterior surface, and a terminal distal face, a pressure-actuated flow control valve spaced distally from the septum body and being operable to selectively prevent fluid flow in a proximal direction, and a septum support assembly for housing the resilient septum body, said septum support assembly including a terminal proximal face defining a generally horizontal plane, an annular internal septum-engaging surface, and a terminal distal surface that presents a flow-through passageway, wherein upon placement of the septum body in the septum support assembly, the septum body is precompressed prior to the cannula being inserted in the septum body to substantially restrict distal displacement of the septum body when the cannula is inserted therein, wherein at rest prior to insertion of the cannula, said terminal proximal face of the septum body is substantially coplanar with the terminal proximal face of the septum support assembly; and inserting a cannula into the slit of the septum body, wherein upon insertion of the cannula into the slit, the septum body is displaced proximally to a greater degree than the septum body is displaced distally, wherein said proximal displacement of said septum body upon insertion of the cannula extends proximally beyond said horizontal plane defined by said terminal proximal face of the septum support assembly.
