1. An infusion pump system, comprising:
- an infusion site interface structure that is adhesively attachable to a skin surface, the infusion site interface structure including;
a frame with a generally flat lower surface, a soft cannula coupled to the frame for penetration of the skin surface when the soft cannula extends below the lower surface of the frame, and an upward extension member that extends above the lower surface such that a septum coupled to the upward extension member extends substantially parallel to the generally flat lower surface of the frame and is positioned above the soft cannula when the soft cannula extends below the lower surface of the frame, wherein the infusion site interface structure lacks tubing above the septum coupled to the upward extension member;
an infusion pump body comprising an infusion site docking area to receive the upward extension member; and
a needle extending from the infusion pump body downwardly toward the lower surface of the frame to penetrate the septum of the infusion site interface structure, wherein the infusion pump body comprises;
a housing having a substantially flat lowermost surface and a substantially flat upper surface, a medicine reservoir in fluid communication with the needle, a drive mechanism, and a control system that governs actuation of the drive mechanism,wherein the infusion site docking area and the upward extension member comprise corresponding guiding members that, during engagement, restrict relative rotational and vertical motion between the pump body and the infusion site interface, andwherein a fluid path between the pump body and the soft cannula intermittently breaks and re-establishes as the pump body repeatedly disconnects from and reconnects with the infusion site interface structure while the infusion site interface structure remains adhesively attached to the skin surface.

Abstract
An infusion pump system is described that increases patient comfort and convenience. The infusion pump system includes an infusion site interface that is releasably connected to an infusion pump body, and has no tubing associated between the infusion site interface and the pump body. The infusion pump body may include a carrier frame that may be adhered to the skin of a user.

9. An infusion pump system, comprising:
-
an infusion site interface structure that is adhesively attachable to a skin surface, the infusion site interface structure including;
a frame with a lower surface, a soft cannula coupled to the frame for penetration of the skin surface when the soft cannula extends below the lower surface of the frame, and a septum that is positioned within a septum support member and above the soft cannula and extends substantially parallel to the lower surface of the frame when the soft cannula extends below the lower surface of the frame;an infusion pump apparatus; and a needle extending from the infusion pump apparatus downwardly toward the soft cannula to penetrate the septum of the infusion site interface structure, wherein the infusion pump apparatus comprises;
a medicine reservoir in fluid communication with the needle, a drive mechanism, and a control system that governs actuation of the drive mechanism, and a housing defining a docking area surrounding at least a portion of the needle and further defining a flat lower surface region adjacent to a lowermost edge of the docking area and proximate to the needle, wherein the docking area and the septum support member comprise corresponding guiding members that, during engagement, restrict relative rotational and vertical motion between the pump body and the infusion site interface, andwherein a fluid path between the infusion pump apparatus and the soft cannula intermittently breaks and re-establishes as the infusion pump apparatus repeatedly disconnects from and reconnects with from the infusion site interface structure while the infusion site interface structure remains adhesively attached to the skin surface. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
