Abstract
A priming assembly for a drug delivery device includes a hub, a base connected to the hub and moveable relative to the hub between a first position and a second position, with the base defining a passageway, a cap defining an interior chamber and a passageway in fluid communication with the interior chamber, and a needle connected to the hub and positioned within the interior chamber of the cap, where the passageway of the base is in fluid communication with the passageway of the cap when the base is in the first position, and where the passageway of the base is isolated from the passageway of the cap when the base is in the second position.
Claims20
A priming assembly for a drug delivery device comprising:
- a hub;
- a base connected to the hub and rotatable relative to the hub between a first position and a second position, the base defining a passageway;
- a cap defining an interior chamber and a passageway in fluid communication with the interior chamber;
- and
- a needle connected to the hub and positioned within the interior chamber of the cap, wherein the passageway of the base is in fluid communication with the passageway of the cap when the base is in the first position, and wherein the passageway of the base is isolated from the passageway of the cap when the base is in the second position.
A drug delivery device comprising:
- a housing;
- a cartridge received within the housing, the cartridge configured to receive a medicament;
- a drive assembly received within the housing and configured to engage the cartridge and dispense medicament from the cartridge;
- a needle actuator assembly received within the housing, the needle actuator assembly comprising a patient needle configured to pierce a user's skin;
- and
- a priming system comprising:
- a cartridge priming assembly comprising a first hub, a first base connected to the first hub and moveable relative to the first hub between a first position and a second position, wherein one of the first hub and the first base defines a first slot and the other of the first hub and the first base comprises a first projection received within the first slot, the first slot having a first end and a second end, and wherein, when the first projection is at the first end of the first slot, the first base is in the first position, and, when the first projection is at the second end of the first slot, the first base is in the second position;
- and
- a needle actuator priming assembly comprising a second hub, a second base connected to the second hub and moveable relative to the second hub between a first position and a second position, wherein one of the second hub and the second base defines a second slot and the other of the second hub and the second base comprises a second projection received within the second slot, the second slot having a first end and a second end, and wherein, when the second projection is at the first end of the second slot, the second base is in the first position, and, when the second projection is at the second end of the second slot, the second base is in the second position.
