Abstract: An infusion set comprising a base and a cap. The base can comprise a portion to be placed against skin, a first cannula extending downwardly below the portion to be placed against skin, and a septum. The cap can comprise a tube and a second cannula. The cap can be configured for removable attachment to the base such that the cap is rotatable with respect to the base while the first cannula, the second cannula, and the tube are in fluid communication.

Abstract: An infusion hub assembly, comprising: a hub received in a hole in a wing, the hub having a bore passing therethrough, with an upper portion of the circular hub having an attachment surface thereon; an infusion cannula extending downwardly away from the wing, the infusion cannula being in fluid communication with the bore passing through the hub; a cover having a bore passing therethrough and having an inner attachment surface adapted to mate with the attachment surface on the upper portion of the hub; and a septum positioned in alignment with the bore passing through the cover. An infusion connector set comprising: a first connector; a septum received in the first connector; a second connector; a septum received in the second connector; and a flanged needle which penetrates both the septums in the first and second connectors when the first and second connectors are connected together.
