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:

a body having an inlet port, a fluid delivery passageway extending from the inlet port, and an inlet boundary extending upstream and downstream from the inlet port parallel to an axis centered within a portion of the fluid delivery passageway;

a cannula having a portion that is coaxial with a portion of the fluid delivery passageway, the cannula also having a cannula passageway having a smallest internal diameter; and

a non-split septum having an outer surface that includes an exposed portion located within the inlet boundary and a remaining non-exposed portion, the exposed portion having a greatest width that is greater than twice the smallest internal diameter;

the fluid delivery device being configured such that an injection needle that enters the exposed portion of the non-split septum in a downstream direction and exits the non-split septum (a) through part of the remaining non-exposed portion that is substantially perpendicular to the axis or (b) through part of the remaining non-exposed portion that has a tangent that is not parallel to the axis and that borders open space within the fluid delivery passageway, exits the non-split septum into open space that is (c) within the first fluid delivery passageway and (d) downstream of the part through which the injection needle exited.

2. The fluid delivery device of claim 1, where the non-split septum has an outer surface area, the majority of which is in contact with other material of the fluid delivery device.

3. The fluid delivery device of claim 1, where the body has a convex shape.

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

5. The fluid delivery device of claim 1, where the outer surface of the non-split septum includes one or more sections that are parallel to the axis, and a majority of the one or more sections is in contact with a surrounding portion or portions of the fluid delivery device.

6. The fluid delivery device of claim 5, where the surrounding portion or portions of the fluid delivery device comprise body material.

7. The fluid delivery device of claim 1, where the non-split septum has a height that runs in a direction parallel to the axis and a middle that is one-half of the height, the middle being in contact with a surrounding portion of the fluid delivery device.

8. The fluid delivery device of claim 7, where the surrounding portion comprises body material.

9. The fluid delivery device of claim 1, where the non-split septum has a height that runs in a direction parallel to the axis and a middle that is one-half of the height, the middle being radially compressed by a surrounding portion of the fluid delivery device.

10. The fluid delivery device of claim 9, where the surrounding portion comprises body material.

11. A fluid delivery device comprising:

a body having an inlet port, a fluid delivery passageway extending from the inlet port, and an inlet boundary extending upstream and downstream from the inlet port parallel to an axis centered within a portion of the fluid delivery passageway;

a cannula having a portion that is coaxial with a portion of the fluid delivery passageway, the cannula also having a cannula passageway having a smallest internal diameter;

a septum having an outer surface that includes an exposed portion located within the inlet boundary and a remaining non-exposed portion, the exposed portion having a greatest width that is greater than twice the smallest internal diameter; and

a needle control portion configured to prevent a needle sized to inject fluid through the fluid delivery device and into a living being from piercing the cannula during normal fluid injection;

the fluid delivery device being configured such that an injection needle that enters the exposed portion of the septum in a downstream direction and exits the septum (a) through part of the remaining non-exposed portion that is substantially perpendicular to the axis or (b) through part of the remaining non-exposed portion that has a tangent that is not parallel to the axis and that borders open space within the fluid delivery passageway, exits the septum into open space that is (c) within the first fluid delivery passageway and (d) downstream of the part through which the injection needle exited.

12. The fluid delivery device of claim 11, where the cannula is integrally formed with, and extends away from, the body.

13. A fluid delivery device comprising:

a body having an inlet port, a fluid delivery passageway extending from the inlet port, and an inlet boundary extending upstream and downstream from the inlet port parallel to an axis centered within a portion of the fluid delivery passageway;

a cannula having a portion that is coaxial with a portion of the fluid delivery passageway, the cannula also having a cannula passageway having a smallest internal diameter;

a septum having an outer surface that includes an exposed portion located within the inlet boundary and a remaining non-exposed portion, the exposed portion having a greatest width that is greater than twice the smallest internal diameter; and
