First Claim
1. An infusion set comprising:
- a base having upper and lower sides, a base cannula extending downwardly from the lower side, 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; and
an infusion cap comprising;
an upper side and a lower side, the infusion cap being adapted to be pressed against the upper side of the base and removably attached to the base after disengagement of the introducer cap from the base, the infusion cap being adapted to rotate with respect to the base while engaged;
an infusion cannula extending downwardly from the lower side of the infusion cap;
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 upon engagement of the infusion cap and the base to place the flexible lumen and the infusion cap in fluid communication with the base cannula;
a guide section configured to align the infusion cap with the port of the base whereby the infusion cannula is directed toward the seal when the infusion cap is removably coupled to 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).
