First Claim
1. A base of an infusion set comprising:
- a substantially planar member having upper and lower sides;
a base cannula extending downwardly from the lower side;
a notched outer rim; and
a port extending upwardly from the upper side, the port being in fluid communication with the base cannula, the port comprising;
a septum adapted to seal said port from fluid communication therethrough, a funnel-shaped section disposed between the septum and the base cannula, wherein the septum is configured to extend downward from the port to the slanted walls of the funnel-shaped section, thereby supporting the septum and resisting downward shear when a member is pressed against the septum; and
an adhesive layer mounted to the lower 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).
