Abstract

Fluid delivery devices, systems and methods. The fluid delivery devices may be used to delivery fluid (e.g., insulin) to a user. The devices may have one or more inlets, and may be configured for use with an injection device, such as a syringe, and/or with a pump.

Claims

1. A fluid delivery device comprising:

two septa that are not in contact with each other, the two septa comprising a first septum and a second septum;

a needle guide in which the first septum is at least partially positioned, the first septum having a width, and the needle guide having a length and an internal diameter along a majority of the length that is narrower than the width;

a body that includes a cap element permanently attached to a base element, the cap and base elements capturing the two septa, the body having first and second fluid delivery passageways;

a cannula coaxial with one of the first and second fluid delivery passageways; and

a second needle guide in contact with both the second septum and the cannula;

where the needle guide is distinct from the cap element and from the base element and the cap element contacts each of the two septa, and the fluid delivery device is configured such that fluid exiting the fluid delivery device into a living being must exit from the cannula.

2. The fluid delivery device of claim 1, where the cannula is integrally formed with, and extends away from, the body.

3. The fluid delivery device of claim 1, where the cannula includes a portion that is positioned within the second fluid delivery passageway.

4. The fluid delivery device of claim 1, where the first septum is positioned within the first fluid delivery passageway.

5. The fluid delivery device of claim 4, where the body includes two rotation-restricting recesses, and the fluid delivery device further comprises:

an insertion device comprising an insertion device hub that includes two rotation-restricting protrusions, each of which is configured to extend into a respective one of the two rotation-restricting recesses.

6. The fluid delivery device of claim 5, further comprising:

a needle guard coupled to the body.

7. The fluid delivery device of claim 6, further comprising:

an adhesive layer attached to the body.

8. The fluid delivery device of claim 7, where the first fluid delivery passageway feeds into the second fluid delivery passageway, the cannula is coaxial with and positioned partially within the second fluid delivery passageway, and the second needle guide is positioned within the cannula.

9. The fluid delivery device of claim 8, where the first fluid delivery passageway is closer to being parallel with the adhesive layer than to being perpendicular to the adhesive layer.

10. The fluid delivery device of claim 9, where the needle guide is positioned within the first fluid delivery passageway.
