Abstract

Systems and methods for a fluid reservoir for use with a fluid infusion device which is automatically filled are provided. A set connector for use with a fluid reservoir of a fluid infusion device includes a body for defining a fluid flow path out of the fluid reservoir. The body includes at least one locking tab that cooperates with a portion of the fluid infusion device to removably couple the body to a proximal end of the fluid reservoir. The body is movable between a first position, in which the fluid flow path is obstructed, and a second position, in which the fluid flow path is open.

Claims

1. A set connector for use with a fluid reservoir of a fluid infusion device, the set connector comprising:

a body for defining a fluid flow path out of the fluid reservoir, the body including at least one locking tab that cooperates with a portion of the fluid infusion device to removably couple the body to a proximal end of the fluid reservoir,

wherein the body is movable between a first position, in which the fluid flow path is obstructed, and a second position, in which the fluid flow path is open.

2. The set connector of claim 1, wherein the body has a top surface opposite a bottom surface, and the at least one locking tab is formed along a perimeter of the body near the bottom surface.

3. The set connector of claim 1, wherein the at least one locking tab has a ramp surface to engage a corresponding ramp surface of the fluid infusion device.

4. The set connector of claim 1, wherein the at least one locking tab has a lock surface to contact a corresponding lock surface of the fluid infusion device to prevent movement of the set connector relative to the fluid reservoir.

5. The set connector of claim 1, wherein the at least one locking tab comprises two locking tabs formed so as to be spaced apart along a perimeter of the body.

6. The set connector of claim 1, wherein the body includes an engagement feature to engage a portion of the fluid reservoir to move the portion of the fluid reservoir as the body moves from the first position to the second position.

7. The set connector of claim 1, wherein the body further comprises at least one pinch surface adjacent to the at least one locking tab.

8. The set connector of claim 7, wherein the at least one pinch surface comprises two pinch surfaces formed so as to be spaced apart along a perimeter of the body.

9. The set connector of claim 2, further comprising a hollow tubing, the hollow tubing coupled to the top surface of the set connector to define a fluid flow path from the set connector.

10. The set connector of claim 2, further comprising a hollow tubing, the hollow tubing coupled to the perimeter of the body between the top surface and the bottom surface to define a fluid flow path from the set connector.

11. The set connector of claim 1, wherein the set connector is needleless.

12. A set connector for use with a fluid reservoir of a fluid infusion device, the set connector comprising:

a piercing device for defining a fluid flow path out of the fluid reservoir; and

a body coupled to the piercing device, the body including at least one locking tab that cooperates with a proximal end of the fluid reservoir to removably couple the body to the fluid reservoir.

13. The set connector of claim 12, wherein the body has a first end and a second end, and the at least one locking tab is defined at the second end.

14. The set connector of claim 13, wherein the body comprises at least one pinch surface at the first end.

15. The set connector of claim 12, wherein the at least one locking tab includes a protrusion to engage a portion of the fluid reservoir.

16. A set connector for use with a fluid reservoir of a fluid infusion device, the set connector comprising:

a body for defining a fluid flow path out of the fluid reservoir, the body including a top surface and a bottom surface, with the top surface including an engagement feature to engage a portion of the fluid reservoir and the bottom surface including at least one locking tab,

wherein the body is movable between a first position, in which the fluid flow path is obstructed, and a second position, in which the fluid flow path is open, and the engagement feature moves the portion of the fluid reservoir as the body moves from the first position to the second position.

17. The set connector of claim 16, wherein the at least one locking tab has a ramp surface to engage a corresponding ramp surface of the fluid infusion device.

18. The set connector of claim 16, wherein the at least one locking tab has a lock surface to contact a corresponding lock surface of the fluid infusion device to prevent movement of the set connector relative to the fluid reservoir.

19. The set connector of claim 16, wherein the body further comprises at least one pinch surface adjacent to the at least one locking tab.

20. The set connector of claim 16, further comprising a hollow tubing, the hollow tubing coupled to the top surface of the set connector to define a fluid flow path from the set connector.
