Abstract

An infusion set for use with a fluid infusion device is provided. The infusion set can include a mount including a projection having a bore. The projection can be surrounded at least partially by a recess defined through a surface of the mount, and the mount can include at least one rib that spans the recess. The infusion set can include a fluid outlet coupled to at least a portion of the bore of the projection and a coupling device to couple the infusion set to a user. The coupling device can be coupled to the surface and the at least one rib of the mount.

Claims

1. An infusion set for use with a fluid infusion device, comprising:

a mount including a projection having a bore, the projection surrounded at least partially by a recess defined through a surface of the mount, the mount including at least one rib that spans the recess;

a fluid outlet coupled to at least a portion of the bore of the projection; and

a coupling device to couple the infusion set to a user, the coupling device coupled to the surface and the at least one rib of the mount.

2. The infusion set of claim 1, wherein the mount has a distal end opposite a proximal end that includes the surface and the at least one rib.

3. The infusion set of claim 2, further comprising:

a connector to fluidly couple the fluid infusion device to the infusion set,

wherein the connector is coupled to the distal end of the mount to fluidly couple the fluid outlet with the fluid infusion device.

4. The infusion set of claim 1, wherein the at least one rib further comprises a plurality of ribs.

5. The infusion set of claim 4, wherein the projection is substantially annular and the plurality of ribs are substantially evenly spaced about a perimeter of the projection.

6. The infusion set of claim 4, wherein the coupling device is solely coupled to the surface and the plurality of ribs.

7. The infusion set of claim 6, wherein the coupling device further comprises an adhesive.

8. The infusion set of claim 1, wherein the bore has a first diameter that is about equal to a second diameter of the fluid outlet.

9. The infusion set of claim 2, wherein the projection extends from the distal end to the proximal end.

10. The infusion set of claim 1, wherein the infusion set is an insulin infusion set for use with an insulin infusion device.

11. An infusion set for use with a fluid infusion device, comprising:

a connector to fluidly couple the fluid infusion device to the infusion set;

a mount having a distal end coupled to the connector and a proximal end, the mount including a projection having a bore that extends along an axis, the proximal end including a plurality of ribs that extend from a surface of the proximal end to the projection, the plurality of ribs arranged to lie in a plane transverse to the axis;

a fluid outlet coupled to at least a portion of the bore of the mount to be in fluid communication with the fluid infusion device through the connector; and

a coupling device to couple the infusion set to a user, the coupling device coupled to the surface and each of the plurality of spaced apart ribs of the proximal end.

12. The infusion set of claim 11, wherein the projection is surrounded at least partially by a recess defined through the surface of the proximal end, and each of the plurality of ribs span the recess.

13. The infusion set of claim 12, wherein the plurality of ribs are substantially evenly spaced about a perimeter of the projection.

14. The infusion set of claim 13, wherein the plurality of ribs are symmetric with respect to the axis.

15. The infusion set of claim 12, wherein the projection is substantially annular and the plurality of ribs are substantially evenly spaced about a perimeter of the projection.

16. The infusion set of claim 11, wherein the coupling device is solely coupled to the surface and the plurality of ribs.

17. The infusion set of claim 16, wherein the coupling device further comprises an adhesive.

18. The infusion set of claim 11, wherein the bore has a first diameter of about 0.8 millimeters.

19. The infusion set of claim 15, wherein the projection extends from the distal end to the proximal end.
