Abstract

A set connector assembly for a fluid infusion device is provided. The set connector assembly includes a connector having a body. The body defines a graspable portion and a coupling portion, and the coupling portion is to be received within a portion of the fluid infusion device. The graspable portion has at least one wing that defines at least one locking tab for locking the connector to the fluid infusion device. The graspable portion is movable relative to the body to move the connector between a first, locked position and a second, unlocked position relative to the fluid infusion device.

Claims

1. A set connector assembly for a fluid infusion device, comprising:

a connector having a body, the body defining a graspable portion and a coupling portion, the coupling portion to be received within a portion of the fluid infusion device, the graspable portion having at least one wing that defines at least one locking tab for locking the connector to the fluid infusion device, the at least one wing includes a first arm and a first flange, and the at least one locking tab is defined on the first flange so as to extend beyond a perimeter of the body, the first flange includes a surface, and an area of the surface includes a marking, and the graspable portion is movable relative to the coupling portion to move the connector between a first, locked position and a second, unlocked position relative to the fluid infusion device,

wherein the marking comprises a trademark and a surface of the at least one locking tab includes the marking such that the marking extends over the area of the surface of the flange and the surface of the at least one locking tab.

2. The set connector assembly of claim 1, wherein the at least one wing comprises two wings, and the at least one locking tab comprises two locking tabs, with each of the locking tabs defined on a respective one of the wings.

3. The set connector assembly of claim 1, wherein the graspable portion includes a main branch that couples the graspable portion to the coupling portion, and the at least one wing is coupled to the main branch at one end.

4. The set connector assembly of claim 3, wherein the main branch couples the graspable portion to the coupling portion such that a gap is defined between the at least one wing and the coupling portion.

5. The set connector assembly of claim 3, wherein the main branch defines a bore for receiving a needle and a tube to define a fluid flow path out of the fluid infusion device.

6. The set connector assembly of claim 1, wherein the marking comprises at least one of a letter, a symbol and a graphical icon.

7. The set connector assembly of claim 1, wherein the at least one locking tab is defined near an end of the first arm.

8. The set connector assembly of claim 1, wherein the at least one locking tab is defined on a perimeter of the first flange so as to be defined between a first end and a second end of the first arm.

9. A set connector assembly for a fluid infusion device, comprising:

a connector having a body that defines a graspable portion and a coupling portion, the coupling portion to be received within a portion of the fluid infusion device, and the graspable portion including;

a first wing that defines a first locking tab to lock the connector to the fluid infusion device, the first wing includes a first arm and a first flange, the first locking tab defined on the first flange so as to extend beyond a perimeter of the body;

a second wing that defines a second locking tab to lock the connector to the fluid infusion device, the second wing includes a second arm and a second flange, the second locking tab defined on the second flange so as to extend beyond a perimeter of the body; and

a main branch having a first end and a second end, with the first wing coupled to the first end and the second wing coupled to the second end, the main branch couples the graspable portion to the coupling portion such that a first gap is defined between the first wing and the coupling portion, and a second gap is defined between the second wing and the coupling portion,

wherein the graspable portion is movable relative to the coupling portion to move the connector between a first, locked position and a second, unlocked position relative to the fluid infusion device, each of the first flange and the second flange include a surface, and the surface of each of the first flange and the second flange has an area that includes a marking, the marking comprises at least one of a letter, a symbol and a graphical icon, and the first locking tab and the second locking tab each include a second surface, and the second surface of each of the first locking tab and the second locking tab includes a portion of the marking.

10. The set connector assembly of claim 9, 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.

11. The set connector assembly of claim 9, wherein the first wing is coupled to the first end by a living hinge, and the second wing is coupled to the second end by a second living hinge.

12. The set connector assembly of claim 9, wherein the body defines a longitudinal axis, and the first flange and the second flange extend along an axis transverse to the longitudinal axis.
