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.

First claim

What is claimed is:

1 . A fluid infusion device, comprising:
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 including a connector having a body that defines a graspable portion and a coupling portion, the coupling portion receivable within the housing, the graspable portion having at least one wing that defines a locking tab for engaging the lock, and the at least one wing is movable relative to the body to disengage the locking tab with the lock.

2 . The fluid infusion device of claim 1 , wherein that housing includes an opening that receives a fluid reservoir, and a retaining ring is coupled to the housing about the opening and defines the lock.

3 . The fluid infusion device of claim 2 , 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.

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

5 . The fluid infusion device of claim 3 , 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.

6 . The fluid infusion device of claim 2 , wherein the coupling portion is coupled to the fluid reservoir.

7 . The fluid infusion device of claim 3 , wherein the graspable portion further comprises a main branch coupled between the first wing and the second wing, the main branch couples the graspable portion to the coupling portion and the main branch includes a bore that is in fluid communication with the fluid reservoir.

8 . The fluid infusion device of claim 3 , wherein the first wing includes a first arm and a first flange, and the first locking tab is defined on the first flange such that the first locking tab extends beyond a perimeter of the body.

9 . The fluid infusion device of claim 8 , wherein the first flange includes a surface, and an area of the surface includes a marking.

10 . The fluid infusion device of claim 9 , wherein the first locking tab includes a second surface, and the second surface and the area include the marking.

11 . The fluid infusion device of claim 10 , wherein the marking is a trademark.

12 . A fluid infusion device, comprising:
a fluid reservoir; a housing that includes an opening that receives the 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 housing and coupled to the fluid reservoir, and the graspable portion includes at least one wing that defines a locking tab for engaging the at least one lock, 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 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 fluid reservoir from the housing.

13 . The fluid infusion device of claim 12 , wherein the at least one wing is movable relative to the body to disengage the locking tab with the at least one lock.

14 . The fluid infusion device of claim 12 , 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.

15 . The fluid infusion device of claim 14 , wherein the first lock is spaced apart from the second lock about a perimeter of the retaining ring.

16 . The fluid infusion device of claim 14 , wherein the graspable portion further comprises a main branch coupled between the first wing and the second wing, the main branch couples the graspable portion to the coupling portion and the main branch includes a bore that is in fluid communication with the fluid reservoir.

17 . The fluid infusion device of claim 16 , 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 gap.

18 . The fluid infusion device of claim 16 , 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.

19 . The fluid infusion device of claim 18 , 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.

20 . The fluid infusion device of claim 12 , wherein the fluid infusion device is an insulin infusion device.
