A recently granted patent (Publication Number: US11918773B2) discloses a method for cleaning a catheter hub using a unique cleaning cap with external threads and a cleaning member. The cleaning cap includes two or more threaded members with helical threads that flex radially to engage with the external threads of the hub. The cleaning member, which can be made of foam or fabric, contains disinfecting substances or antiseptic fluids to ensure thorough cleaning of the hub.

Additionally, the cleaning cap features actuation pins for engagement with a cleaning apparatus, a cleaning pin for intra-valvular cleaning, and a self-cleaning solution that renders the hub superhydrophobic after cleaning. The method involves rotating the cleaning cap relative to the hub while applying a constant axial force and leaving the cap on the hub to maintain a sterile environment. The cap also includes indicators for wetness or dryness of the cleaning solution, making it a comprehensive solution for catheter hub cleaning.
