Larger stepped connector to help prevent connection to IV tubes while still providing a secure fit with feeding tubes. Feeding ports are incompatible with luer lock or IV connections, reducing the risk of accidental connection or infusion. Purple color to indicate nutritional port, not for IV access. Feeding tubes are transparent, with purple Sentinel Line™ and Sentinel Eye™ radiopaque markings to assist in proper tube placement. Feeding tubes have markings placed every centimeter from 5-25 cm providing a visual indicator to assist in tube placement and to check migration. Bifurcated extension sets provide a section port for irrigation and medication delivery, preventing the clinician from having to disconnect the extension set.
