Disinfecting cap with pressure seal capability

A cap comprising:

• a housing having a proximal portion and a distal portion comprising
• a top wall positioned between the proximal portion and the distal portion,
• a cylindrical sidewall forming a first cavity, and
• an open bottom formed by the cylindrical sidewall with an opening to the first cavity within the housing for receiving a needleless connector having an open lumen;
• and
• an insert disposed within the first cavity, the insert having closed distal end comprising a distal wall, an open proximal end, a sidewall extending proximally from the distal wall toward the open proximal end, the sidewall having a split-thread protrusion/insert integrally formed with the distal wall, the split-thread protrusion/insert having an inner surface and an outer surface, the inner surface of the split-thread protrusion/insert defining a second cavity,
• an inner thread on the inner surface of the split-thread protrusion/insert, the inner thread being sufficient to interlock with a mating feature of a female needleless connector,
• an outer thread on the outer surface of the split-thread protrusion/insert, the outer thread being sufficient to interlock with a mating feature of a male needleless connector;
• a piston-shaped sealing foam;
• an absorbent reservoir material configured within the second cavity;
• a disinfectant or an antimicrobial agent;
• and
• a seal for maintaining the disinfectant or an antimicrobial agent within the second cavity prior to use of the cap.
