Subcutaneous infusion set with side port fluid connector
An infusion set preferably for use with an inserter is disclosed. The infusion set includes a septum cap that encapsulates an upper resilient septum and a lower resilient septum of a base, and includes at least one radial port to receive insertion of a blunt cannula when an extension set hub is engaged with the infusion set in a direction substantially parallel to the skin surface. The extension set hub is configured to provide a snap-fit engagement with the septum cap, wherein the blunt cannula of the extension set hub is guided through the radial port of the septum cap and penetrates the interface between the upper septum and the lower septum. The extension set hub and the septum cap can be rotated in a 360 degree manner about the base of the infusion set.
1. An infusion set, comprising:
a base;
an upper septum;
a lower septum, said upper and lower septa together forming a substantially cylindrical hollow body having a chamber therein;
a septum cap, comprising
a substantially cylindrical hollow body enclosing said upper and lower septa; and
a substantially circular exterior outer body, wherein
said septum cap comprises at least one radial port and at least one axial port; and
an extension set hub including a snap-ring comprising a substantially circular ring and a hinge configured to deflect to allow said circular ring to deflect, circumferentially surround and snap fit to said substantially circular exterior outer body of said septum cap.
2. The infusion set of claim 1 , further comprising:
a blunt cannula configured for insertion through said radial port and passing through an interface between said upper septum and said lower septum.
3. The infusion set of claim 2 , further comprising:
a plurality of guidance walls flexibly extending from said snap ring.
4. The infusion set of claim 3 , wherein said plurality of guidance walls is configured to releasably secure an outer circumference of said septum cap.
5. The infusion set of claim 3 , wherein said plurality of guidance walls is configured to guide said blunt cannula through said radial port and through said interface between said upper septum and said lower septum.
6. The infusion set of claim 1 , wherein said blunt cannula is configured to rotatably slide through an interface between said upper septum and said lower septum in a 360 degree manner.
7. The infusion set of claim 1 , wherein said septum cap is configured to rotatably couple with said base.
8. The infusion set of claim 1 , wherein the upper septum has a solid construction.
9. An infusion set, comprising:
a base;
a septum comprising a hollow body having a chamber enclosed therein;
a septum cap comprising
a hollow body enclosing said septum; and
a substantially circular exterior outer body, wherein
said septum cap comprises at least one radial port and at least one axial port; and
an extension set hub including a snap-ring comprising a substantially circular ring and a plurality of ring-shaped guidance walls extending therefrom that are circumferentially shaped to mate with the substantially circular exterior outer body of the septum cap.
10. The infusion set of claim 9 , further comprising:
a cannula configured for insertion through said radial port.
11. The infusion set of claim 9 , wherein said plurality of guidance walls is configured to guide said cannula through said radial port.
12. An infusion set, comprising:
a base;
at least one septum having an interface between upper and lower portions thereof;
a septum cap enclosing said septum, wherein said septum cap comprises at least one radial port and at least one axial port; and
an extension set hub having a blunt cannula configured for insertion through said radial port and through the interface between the upper and lower portions of said septum, said blunt cannula being inserted when said extension set hub is moved in a direction substantially parallel to a skin surface, and said blunt cannula being configured to continuously rotate up to 360° around said septum at said interface.
