Abstract

A fluid infusion device is provided. The fluid infusion device includes a housing that includes a lock and a set connector assembly removably coupled to the housing to define a fluid flow path from the fluid infusion device. The set connector assembly includes a connector having a body that defines a graspable portion and a coupling portion. The coupling portion is receivable within the housing, and the graspable portion has at least one wing that defines a locking tab for engaging the lock. The at least one wing is movable relative to the body to disengage the locking tab with the lock.

Claims

1. A fluid infusion device, comprising:

a removable fluid reservoir;

a housing that defines an opening that receives the removable fluid reservoir and the housing includes a retaining ring having a lock, the retaining ring surrounds the opening; and

a set connector assembly removably coupled to the housing to define a fluid flow path from the fluid infusion device, the set connector assembly including a connector having a body that defines a graspable portion and a coupling portion, the coupling portion receivable within the opening of the housing and coupled to the removable fluid reservoir, the graspable portion having a main branch and at least one wing coupled to the main branch that defines a locking tab for engaging the lock, the main branch extending from the coupling portion, the main branch defines a bore that extends along a longitudinal axis of the connector to define the fluid flow path, the locking tab extends outward from the at least one wing beyond a perimeter of the coupling portion of the connector to engage the lock and the at least one wing is movable relative to the coupling portion to disengage the locking tab with the lock.

2. The fluid infusion device of claim 1, wherein the at least one wing of the graspable portion comprises a first wing defining a first locking tab and a second wing defining a second locking tab, and the retaining ring includes a first lock that receives the first locking tab and a second lock that receives the second locking tab.

3. The fluid infusion device of claim 2, wherein the first lock is spaced apart from the second lock about a perimeter of the retaining ring.

4. The fluid infusion device of claim 2, wherein each of the first lock and the second lock include a planar wall that cooperates with the first locking tab and the second locking tab to lock the connector to the housing.

5. The fluid infusion device of claim 2, wherein the main branch is coupled between the first wing and the second wing.

6. The fluid infusion device of claim 2, wherein the first wing includes a first arm and a first flange, and the first locking tab is defined on the first flange.

7. The fluid infusion device of claim 6, wherein the first flange includes a surface, and an area of the surface includes a marking.

8. The fluid infusion device of claim 7, wherein the first locking tab includes a second surface, and the second surface includes the marking such that the marking extends over the area of the surface of the flange and the second surface of the at least one locking tab.

9. The fluid infusion device of claim 8, wherein the marking is a trademark.

10. A fluid infusion device, comprising:

a removable fluid reservoir;

a housing that includes an opening that receives the removable fluid reservoir;

a retaining ring coupled to the housing about the opening that includes at least one lock; and

a set connector assembly removably coupled to the housing to define a fluid flow path from the fluid infusion device, the set connector assembly including a connector having a body that defines a graspable portion and a coupling portion, the coupling portion receivable within the opening of the housing and coupled to the removable fluid reservoir, and the graspable portion includes a main branch and at least one wing that defines a locking tab for engaging the at least one lock, the main branch extending from the coupling portion, the main branch defines a bore that extends along a longitudinal axis of the connector to define the fluid flow path and the locking tab extends outward from the at least one wing beyond a perimeter of the coupling portion,

wherein the connector is movable relative to the housing between a first position, in which the locking tab engages the at least one lock to retain the removable fluid reservoir within the housing, and a second position, in which the locking tab is disengaged from the at least one lock to enable the removal of the removable fluid reservoir from the housing.

11. The fluid infusion device of claim 10, wherein the at least one wing is movable relative to the coupling portion to disengage the locking tab with the at least one lock.

12. The fluid infusion device of claim 10, wherein the at least one wing of the graspable portion comprises a first wing defining a first locking tab and a second wing defining a second locking tab, and the at least one lock of the retaining ring comprises a first lock that receives the first locking tab and a second lock that receives the second locking tab.

13. The fluid infusion device of claim 12, wherein the first lock is spaced apart from the second lock about a perimeter of the retaining ring.

14. The fluid infusion device of claim 12, wherein the main branch coupled between the first wing and the second wing.

15. The fluid infusion device of claim 14, wherein the first wing and the second wing are coupled to the main branch so as to be spaced apart from the coupling portion by a first gap and a second gap, respectively.

16. The fluid infusion device of claim 14, wherein the main branch includes a first end and a second end, and the first end is coupled to the first wing and the second end is coupled to the second wing.

17. The fluid infusion device of claim 16, wherein the first wing is coupled to the first end such that the first wing extends from the first end in a direction towards the second end of the main branch, and the second wing is coupled to the second end such that the second wing extends from the second end in a second direction towards the first end.

18. The fluid infusion device of claim 10, wherein the fluid infusion device is an insulin infusion device.
