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.

First claim

1 . A fluid delivery device comprising:
two septa that are not in contact with each other; and a needle guide in which one of the septa is at least partially positioned.

2 . The fluid delivery device of claim 1 , further comprising:
a body having first and second fluid delivery passageways, the second fluid delivery passageways being fed by an inlet port adapted for engagement with an infusion pump connector fitting.

3 . The fluid delivery device of claim 2 , further comprising:
a cannula having a portion that is coaxial with a portion of one of the first and second fluid delivery passageways; the fluid delivery device being configured such that fluid exiting the fluid delivery device into a living being must exit from the cannula.

4 . The fluid delivery device of claim 3 , further comprising:
a passageway closing structure oriented in a first position that at least partially prevents fluid from flowing through the first fluid delivery passageway while allowing fluid to flow unobstructed through the second fluid delivery passageway; the passageway closing structure being movable to a second position that at least partially prevents fluid from flowing through the second fluid delivery passageway while allowing fluid to flow unobstructed through the first fluid delivery passageway.

5 . The fluid delivery device of claim 3 , where the cannula is integrally formed with, and extends away from, the body.

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

7 . A fluid delivery device comprising:
a body having two fluid delivery passageways; a cannula having a portion that is coaxial with a portion of one of the two fluid delivery passageways, the cannula also having a cannula passageway having a smallest internal width; a needle guide having a portion positioned within one of the fluid delivery passageways; and a septum having a portion positioned within the needle guide, the septum also having an accessible portion that is accessible to an injection needle during normal use of the fluid delivery device, the accessible portion having a greatest width that is at least twice as great as the smallest internal width of the cannula.

8 . The fluid delivery device of claim 7 , where one of the fluid delivery passageways is fed by an inlet port adapted for engagement with an infusion pump connector fitting.

9 . The fluid delivery device of claim 7 configured such that fluid exiting the fluid delivery device into a living being must exit from the cannula.

10 . The fluid delivery device of claim 7 , where the two fluid delivery passageways comprise first and second fluid delivery passageways, and further comprising:
a passageway closing structure oriented in a first position that at least partially prevents fluid from flowing through the first fluid delivery passageway while allowing fluid to flow unobstructed through the second fluid delivery passageway; the passageway closing structure being movable to a second position that at least partially prevents fluid from flowing through the second fluid delivery passageway while allowing fluid to flow unobstructed through the first fluid delivery passageway.

11 . The fluid delivery device of claim 7 , where the portion of the needle guide also is positioned within the fluid delivery passageway.

12 . The fluid delivery device of claim 7 , where the cannula is integrally formed with, and extends away from, the body.

13 . The fluid delivery device of claim 7 , where the cannula includes a portion that is positioned within the first fluid delivery passageway.

14 . A fluid delivery device comprising:
a body having first and second fluid delivery passageways; a needle guide having a portion positioned within the first fluid delivery passageway; a first sealing mechanism that substantially prevents fluid from flowing through the first fluid delivery passageway, the first sealing mechanism having a portion positioned in the needle guide; a second sealing mechanism that substantially prevents fluid from flowing through the second fluid delivery passageway, the second sealing mechanism not being in contact with the first sealing mechanism; and a cannula having a portion that is coaxial with a portion of one of first and second fluid delivery passageways; the fluid delivery device being configured such that fluid exiting the fluid delivery device and into a living body must exit the fluid delivery device through the cannula.

15 . The fluid delivery device of claim 14 , where the second fluid delivery passageway is fed by an inlet port adapted for engagement with an infusion pump connector fitting.

16 . The fluid delivery device of claim 14 , further comprising:
a passageway closing structure oriented in a first position that at least partially prevents fluid from flowing through the first fluid delivery passageway while allowing fluid to flow unobstructed through the second fluid delivery passageway; the passageway closing structure being movable to a second position that at least partially prevents fluid from flowing through the second fluid delivery passageway while allowing fluid to flow unobstructed through the first fluid delivery passageway.

17 . The fluid delivery device of claim 14 , where the cannula is integrally formed with, and extends away from, the body.

18 . The fluid delivery device of claim 14 , where the cannula includes a portion that is positioned within the first fluid delivery passageway.
