Abstract

A fluid infusion system includes a housing configured to be adhesively coupled to an anatomy of a user, and a tube configured to extend from the housing for insertion into the anatomy of the user. The tube includes a plurality of conduits defined within the tube. The plurality of conduits include a fluid delivery conduit configured to facilitate a fluidic connection between a fluid source and the anatomy of the user, and one or more conduits configured to accommodate a plurality of electrodes for determining a physiological characteristic of the user.

First claim

What is claimed is:

1. A fluid infusion system comprising:
a housing configured to be adhesively coupled to an anatomy of a user;
a tube configured to extend from the housing for insertion into the anatomy of the user, the tube comprising a plurality of conduits defined within the tube, the plurality of conduits comprising:
a fluid delivery conduit configured to facilitate a fluidic connection between a fluid source and the anatomy of the user, wherein the fluid delivery conduit terminates at an end of the tube, wherein the end of the tube is configured to be inserted into the anatomy of the user, and wherein the end of the tube comprises a fluid outlet, for delivery of fluid into the anatomy of the user, through which the fluid delivery conduit is configured to facilitate the fluidic connection, and
electrode receiving conduits configured to accommodate a plurality of electrodes for determining a physiological characteristic of the user, wherein each conduit of the electrode receiving conduits is configured to extend in parallel with the fluid delivery conduit through the tube,

wherein respective windows of a plurality of windows are each defined along an outer length of the tube at respective locations that are spaced apart from the end of the tube to create respective openings, at the respective locations that are spaced apart from the end of the tube, through the tube and parallel with respective conduits of the electrode receiving conduits, and wherein each window of the plurality of windows is configured to expose a respective electrode of the plurality of electrodes to the anatomy of the user.

2. The fluid infusion system of claim 1 , wherein the fluid source is a fluid delivery device comprising a fluid reservoir.

3. The fluid infusion system of claim 1 , wherein the plurality of electrodes comprises a reference electrode, a counter electrode, and a working electrode.

4. The fluid infusion system of claim 1 , wherein the fluid outlet is a first fluid outlet, and wherein the tube further comprises one or more additional fluid outlets configured to face away from the plurality of windows such that the fluid delivery and the physiological characteristic determination are capable of being performed at different locations of the anatomy of the user.

5. The fluid infusion system of claim 1 , wherein the tube further comprises an outer layer of heat shrink material used to form the electrode receiving conduits adjacent to the fluid delivery conduit, and wherein the respective windows create the respective openings through the outer layer.

6. The fluid infusion system of claim 1 , wherein the tube is inserted into the anatomy of the user using a needle that at least partially envelopes the tube.

7. The fluid infusion system of claim 1 , wherein the tube is inserted into the anatomy of the user using a needle that is extended through the fluid delivery conduit.

8. The fluid infusion system of claim 1 , wherein the fluid delivery conduit comprises a first fluid delivery conduit, wherein the tube further comprises one or more other fluid delivery conduits, and wherein the first fluid delivery conduit, the electrode receiving conduits, and the one or more other fluid delivery conduits are each a respective tubule.

9. The fluid infusion system of claim 1 , wherein the plurality of electrodes correspond to one or more wires of a ribbon cable, and wherein the fluid delivery conduit is defined by an enclosure formed using the ribbon cable.

10. The fluid infusion system of claim 1 , wherein a size of at least two of the plurality of windows is different.

11. A fluid infusion system comprising:
a housing configured to be adhesively coupled to an anatomy of a user;
a fluid delivery tube configured to extend from the housing for insertion into the anatomy of the user, thereby facilitating a fluidic connection between a fluid source and the anatomy of the user;
a shape-memory wire; and
a substrate that encases the shape-memory wire and on which a plurality of electrodes are formed, the plurality of electrodes being configured to determine a physiological characteristic of the user, the substrate being coupled to the fluid delivery tube, wherein the shape-memory wire is configured to move the plurality of electrodes or one or more fluid outlets defined in the fluid delivery tube between a first state where the plurality of electrodes and the one or more fluid outlets are separated by a first distance and a second state where the plurality of electrodes and the one or more fluid outlets are separated by a second distance that is greater than the first distance such that the plurality of electrodes are positioned to determine the physiological characteristic at a different location from where the one or more fluid outlets defined in the fluid delivery tube are positioned to dispense fluid.

12. The fluid infusion system of claim 11 , wherein the plurality of electrodes are configured to face a first direction, and wherein the one or more fluid outlets are configured to face a second direction that is opposite to the first direction.

13. The fluid infusion system of claim 11 , wherein the plurality of electrodes are configured to face a first direction, and wherein the one or more fluid outlets are configured to face a second direction that is perpendicular to the first direction.
