Abstract:
1. An infusion set comprising: a substantially round base 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, and the port comprising a septum adapted to seal said port from fluid communication therethrough, the septum being substantially flush with a top edge of the port, and the port being substantially cylindrical and the port having an outer diameter substantially closer in size to the diameter of the septum than to the diameter of the base; an adhesive layer mounted to the lower side of the base; an introducer cap adapted to be pressed against the upper side of the base and removably coupled to the base, the introducer cap comprising upper and lower sides, and a needle extending downwardly from the lower side, the needle being adapted to extend through the septum on the upper side of the base and through the base cannula on the lower side of the base, whereby the attached base and introducer cap are adapted to be pressed against a patient's skin such that the introducer needle pierces the skin and the adhesive layer on the lower side of the base contacts the skin, the introducer cap having at least one retaining member configured to couple to the notched outer rim of the base and two tabs extending upwardly from the upper side of the introducer cap configured to decouple the at least one retaining member from the notched rim when a force is applied to at least one of the tabs; 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, 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.
