Infusion set
First Claim
1. An infusion set comprising:
- a substantially planar base having upper and lower sides, a base cannula extending downwardly from the lower side, an outer ring having a notched edge along the lower side extending around the outer periphery of the base, and a port extending upwardly from the upper side, the port being in fluid communication with the base cannula, and the port comprising a septum adapted to seal said port from fluid communication therethrough;
an adhesive layer mounted to the lower side of the base adapted to be pressed against the skin of a patient;
an infusion cap comprising an upper side and a lower side and at least one retaining member configured to couple with the outer ring of the base such that the infusion cap is adapted to be pressed against the upper side of the base and removably coupled to the base at the outer ring, the infusion cap being adapted to rotate in a complete circle with respect to the base while coupled, the infusion cap comprising an infusion cannula extending downwardly from the lower side of the infusion cap, and an elongate flexible lumen in fluid communication with the infusion cannula, the infusion cannula being adapted to extend through the septum on the upper side of the base.

Abstract
An infusion set comprises a base member (60), an introducer cap (64), and an infusion cap (54). The base member (60) preferably comprises a soft cannula (52) extending from a lower side (118) of the base member (60), and a port (62) on an upper side (92) thereof. The port (62) is configured to be in fluid communication with the cannula (52). The port (62) also comprises a septum (130) adapted to seal the port (62) against unwanted fluid flow. The introducer cap (64) is adapted to be mounted to the base member (60) and has a needle (66) adapted to extend through the septum (130) and said soft cannula (52) in an assembled position. The infusion cap (54) comprises a lumen (160) adapted to receive an elongate flexible tube (162). The infusion cap (54) also comprises a hard cannula (170) adapted to be inserted through the septum (130) and to place said soft cannula (52) in fluid communication with said lumen (160).
