Abstract: A cap is configured to provide antimicrobial protection to a female luer port of an intravenous device. The cap distributes an antimicrobial solution within the intraluminal surfaces of the port when the cap is connected to the port. A cap may also be designed to distribute an antimicrobial solution around the exterior surfaces of the port. Once connected to a port, the cap can form a seal that minimizes the evaporation of the antimicrobial solution from within the lumen of a port. The cap can therefore provide antimicrobial protection against another device that is connected to the port once the cap is removed.
