Subcutaneous infusion set with side port fluid connector

A method of coupling an extension set hub comprising a blunt cannula, with an infusion set comprising a base, an upper septum, a lower septum, an interface between said upper and lower septa, and a septum cap enclosing said upper and lower septa, said septum cap comprising at least one radial port and at least one axial port, the method comprising the steps of:

• affixing said base to a skin surface of a user;
• moving said extension set hub in a direction substantially parallel to said base until said blunt cannula passes through said radial port and between said upper septum and said lower septum within said septum cap;
• and
• rotating said extension set hub freely around said interface until reaching a desired position.
