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.
Claims19
A fluid delivery device comprising:
- a body having a first inlet, a first fluid delivery passageway extending from the first inlet, and a second fluid delivery passageway;
- a cannula having a portion that is coaxial with a portion of one of the first and second fluid delivery passageways;
- and
- a passageway closing structure oriented in a first position that substantially prevents fluid from flowing from the first inlet through the first fluid delivery passageway and out of the body, while allowing fluid to flow through the second fluid delivery passageway;
- the passageway closing structure being movable to a second position that substantially prevents fluid from flowing through the second fluid delivery passageway while allowing fluid to flow through the first fluid delivery passageway.

A fluid delivery device comprising:
- a body having first and second fluid delivery passageways;
- a cannula having a portion that is coaxial with a portion of one of the first and second fluid delivery passageways;
- and
- a passageway closing structure oriented in a first position that at least partially blocks the first fluid delivery passageway while leaving the second fluid delivery passageway substantially unobstructed;
- the passageway closing structure being movable to a second position that at least partially prevents fluid from flowing through the second fluid delivery passageway and out of the body, while leaving the first fluid delivery passageway substantially unobstructed.
2 more elements
A fluid delivery device comprising:
- a body having first and second fluid delivery passageways, the second fluid delivery passageway meeting the first fluid delivery passageway at a junction location;
- a cannula having a portion that is coaxial with a portion of one of the first and second fluid delivery passageways;
- and
- a passageway closing structure oriented in a first position that at least partially prevents fluid from flowing in a downstream direction through a portion of the first fluid delivery passageway that is upstream of the junction location, 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 and out of the body while allowing fluid to flow unobstructed through the first fluid delivery passageway.
