Patent ID: 8430847

Claim:
A medicine infusion pump system, comprising: an infusion site interface structure that is adhesively attachable a skin surface, the infusion site interface structure comprising: a frame with a lower surface facing toward the skin surface, a soft cannula coupled to the frame for extension below the lower surface of the frame and configured for subcutaneously insertion through the skin surface to at least partially define a fluid path, and a septum arranged in the fluid path and having a major surface that extends generally parallel to the lower surface of the frame; and an infusion pump device is releasably attachable to the frame of the infusion site interface structure so that a needle extending from the infusion pump device penetrates the septum of the infusion site interface, wherein when the infusion pump device is releasably attached to the frame of the infusion site interface structure, the infusion pump device dispenses a medicine through the fluid path from a medicine reservoir housed in the infusion pump device, through the penetrated septum of the infusion site interface structure, and through the soft cannula extending below the lower surface of the frame, wherein the fluid path is configured to be intermittently broken and re-established when the infusion pump device which houses the medicine reservoir is temporarily disconnected from and reconnected with from infusion site structure while the infusion site interface structure is adhesively attached the skin surface.
