Neutral pressure split septum luer access device

A luer receiving valve for receiving a male luer mounted within a threadable luer lock connector shroud, the valve comprising:

• a luer valve housing having a channel for fluid passage and an inlet, an outlet, and a proximal housing portion sized to be received into the luer lock connector shroud adjacent the inlet, and a distal housing portion having at least one transversely enlarged chamber defining at least one internal wall, the chamber having a diameter greater than the shroud, a septum positioned within the channel, the septum defining an upper septum portion with an outer face mounted adjacent the inlet, and a lower septum portion mounted within said transversely enlarged chamber, the lower septum portion having a proximal lower septum portion projecting laterally within the chamber, and a distal lower septum portion including a distal sealing portion in sealing contact with the distal housing portion, the septum further having a central slit through the face, the slit defining a longitudinal axis projecting distally from said face, the slit being configured to allow insertion and penetration of the male luer into the central slit, the lower septum portion further having a transverse separation extending between the proximal lower septum portion and the distal lower septum portion from adjacent an outer perimeter of the distal lower septum portion inwardly to such an extent that a central septum portion connecting said proximal lower septum portion and said distal lower septum portion has a width in a direction perpendicular to the longitudinal axis of said slit which is less than an inner diameter of said proximal housing portion, wherein said central septum portion has a width in a direction perpendicular to the longitudinal axis of said slit which is less than an outer diameter of said male luer.
