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.

Claims

12. A method of operating an infusion pump system, comprising:

adhering an infusion site interface structure to a skin surface, the infusion site interface structure comprising;

a frame with a lower surface facing toward the skin surface and an upward facing surface that is opposite the lower surface, a soft cannula coupled to the frame and extending below the lower surface of the frame for insertion subcutaneously through the skin surface to at least partially define a fluid path, and a septum arranged in the fluid path and coupled to the frame in a position above the upward facing surface of the frame; and

releasably connecting an infusion pump device to the frame of the infusion site interface structure adhered to the skin such that the infusion pump device is mechanically coupled to the frame of the infusion site interface structure and a piercing member of the infusion pump device penetrates the septum of the infusion pump device, through the penetrated septum of the infusion site interface structure, and through the soft cannula inserted subcutaneously through the skin surface;

causing the infusion pump device to dispense medicine into a user'"'"'s body via the fluid path from the medicine reservoir housed in the infusion pump device, through the penetrated septum of the infusion site interface structure, and through the soft cannula inserted subcutaneously through the skin surface;

disconnecting and reconnecting the infusion pump device to the infusion site interface structure so that the fluid path is broken and re-established without replacement of the infusion site interface structure.
