Abstract
A catheter connector has a hydrophobic end cap or washer located around the end opening to the connector's lumen. The diameter and length of the lumen below the washer is sufficiently large enough to accommodate an absorbent tubular filter that changes color when exposed to fluid. The washer acts to limit the size of the water droplet that might adhere to the end of the catheter and help maintain surface tension on the droplet to prevent it from entering the lumen. The hydrophilic tubular filter absorbs any water that might pass by the washer and thus keeps the lumen hole open.
