Abstract: A neutral pressure split-septum luer access device is described for receiving a luer lock connector. The septum has a plurality of elastomeric columns projecting laterally within a chamber. Each elastomeric column is under sufficient compression so that the columns are bowed and the column strength is reduced by bowing, but the slit sealing force is high. This configuration places the lower portion of the slit in a tightly sealed configuration which is never-the-less receptive to penetration by the male luer which causes the columns to bow further and collapse precipitously with the elastomeric force of the collapsing mass of the columns being carried distally to displace and pop open the central slit distal the tip of the male luer. The septum further provides a transverse separation between the columns and a distal sealing portion so the force of the displacement force to the sealing portion is reduced.
