Infusion set
First Claim
1. An infusion set comprising:
- a base having upper and lower sides, a rigid base cannula permanently attached to and extending downwardly from a portion of the lower side in a substantially fixed orientation, below 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 substantially seal said port from fluid communication therethrough;
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, 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 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;
wherein the infusion cap is adapted to rotate with respect to the base cannula about an axis that is generally perpendicular to the lower side of the base while the base and the infusion cap are engaged and the infusion cannula and the rigid base cannula are in fluid communication.

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).
