While many valves may claim to be split septum, the split-septum devices described in the evidence cited by the CDC were BD Q-Syte^TM Luer Access Split Septum and Interlink. The 2011 Infusion Nursing Standards of Practice defi nes a split septum device as a simple needleless connector with a prepierced septum that can be of blunt cannula or luer-lock design. What makes the BD Q-Syte device a true split septum is the simple fluid path with no internal mechanism. This device eliminates the complexities of mechanical valves, and with them, the places that may harbor bacteria.
