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 substantially 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 an 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 on the lower side of the infusion cap in close proximity to the infusion cannula, the guide section being configured to align the infusion cap with the port of the base whereby the infusion cannula is directed toward the septum when the infusion cap is removably coupled to the base, wherein the guide section extends downwardly from the lower side of the infusion cap beyond the infusion cannula, wherein the guide section is substantially cylindrical, wherein the infusion cap comprises at least one retaining member to attach to the base, and wherein the lowest surface of the guide section is upwardly spaced from the lowest surface of the at least one retaining member.
