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 locking tab to lock the connector to the fluid infusion device, and 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.

First claim

What is claimed is:

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, and the graspable portion includes a hub coupled to the coupling portion and a locking arm having a first end coupled to the hub and a second end that has a locking tab to lock the connector to the fluid infusion device, the hub defines a bore that extends along a longitudinal axis of the connector, the first end of the locking arm coupled to the hub such that a space is defined between the locking tab and the hub to receive a portion of the fluid infusion device, the locking arm 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 and the locking arm extends a distance beyond a perimeter of the coupling portion to provide a force to bias the locking arm into the lock.

2. The set connector assembly of claim 1 , wherein the graspable portion includes a second arm opposite the locking arm.

3. The set connector assembly of claim 1 , wherein the graspable portion comprises at least one wing coupled adjacent to the locking arm.

4. The set connector assembly of claim 1 , wherein the bore is to receive a needle and a tube, to define a fluid flow path out of the fluid infusion device.

5. The set connector assembly of claim 1 , wherein the graspable portion includes a first wing and a second wing coupled to the hub such that the first wing is substantially opposite the second wing about the hub.

6. The set connector assembly of claim 5 , wherein the locking arm is coupled to the hub between the first wing and the second wing.

7. The set connector assembly of claim 5 , wherein at least one of the first wing and the second wing includes an undulating surface at an end.

8. A fluid infusion device, comprising:
a housing that includes a lock and defines an opening that receives a removable fluid reservoir, the lock spaced apart from the opening; and
a set connector assembly removably coupled to the housing to define a fluid flow path from the removable fluid reservoir of the fluid infusion device, the set connector assembly including a connector having a body, the body defining 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 hub coupled to the coupling portion and a locking arm having a first end coupled to the hub and a second end that has a locking tab that engages the lock, the hub defines a bore that extends along a longitudinal axis of the connector for defining the fluid flow path, the locking arm movable relative to the coupling portion to move the connector between a first, locked position and a second, unlocked position relative to the housing and the locking arm extends a distance beyond a perimeter of the coupling portion to provide a force to bias the locking arm into the lock.

9. The fluid infusion device of claim 8 , wherein the lock is coupled to a surface of the housing so as to be adjacent to a fluid reservoir system associated with the fluid infusion device.

10. The fluid infusion device of claim 8 , wherein the graspable portion includes a second arm opposite the locking arm.

11. The fluid infusion device of claim 8 , wherein the graspable portion comprises at least one wing coupled adjacent to the locking arm.

12. The fluid infusion device of claim 8 , wherein the graspable portion includes a first wing and a second wing coupled to the hub such that the first wing is substantially opposite the second wing about the hub and the locking arm is coupled to the hub between the first wing and the second wing.

13. The fluid infusion device of claim 8 , wherein the housing includes a retaining ring coupled to the housing that defines the lock, and the lock includes a pocket that receives the locking tab.

14. The fluid infusion device of claim 9 , wherein the bore is to receive a needle and a tube, the needle receivable within a fluid reservoir of the fluid reservoir system to define the fluid flow path out of the fluid infusion device.

15. A fluid infusion device, comprising:
a removable fluid reservoir;
a housing defining an opening that receives the removable fluid reservoir, the housing including a lock spaced apart from the opening; and
a set connector assembly removably coupled to the housing to define a fluid flow path from the removable fluid reservoir, the set connector assembly including a connector having a body, the body defining a graspable portion and a coupling portion, the coupling portion receivable within the housing and positionable about the removable fluid reservoir, the graspable portion having a hub and a locking arm that has a first end coupled to the hub and a second end that defines a locking tab that engages the lock, the hub coupled to the coupling portion and defining a bore that extends along a longitudinal axis of the connector to define the fluid flow path, the first end of the locking arm coupled to the hub such that a space is defined between the locking tab and the hub to receive a portion of the housing and the locking arm is movable relative to the coupling portion to move the connector between a first, locked position and a second, unlocked position relative to the housing and the locking arm extends a distance beyond a perimeter of the coupling portion to provide a force to bias the locking arm into the lock.

16. The fluid infusion device of claim 15 , wherein the housing includes a retaining ring coupled to the housing that defines the lock, and the lock includes a pocket that receives the locking tab.

17. The fluid infusion device of claim 15 , wherein the graspable portion includes a first wing and a second wing coupled to the hub such that the first wing is substantially opposite the second wing about the hub and the locking arm is coupled to the hub between the first wing and the second wing.
