Abstract
Aerosolizing delivery apparatuses can include cartridges configured to be detachably connected to a delivery device. The cartridges can include: a housing defining a reservoir and a cartridge outlet, the cartridge outlet configured to permit fluid communication between the reservoir and an exterior of the cartridge. A surface of the housing can be configured to define a bypass port between the housing and a surface of the delivery device when the cartridge is assembled with the delivery device.
Claims24
A cartridge configured to be detachably connected to a delivery device, the cartridge comprising:
- a housing defining a reservoir and a cartridge outlet, the cartridge outlet configured to permit fluid communication between the reservoir and an exterior of the cartridge,
- wherein the cartridge is configured to form a junction with the delivery device when the cartridge is assembled with the delivery device and an outer surface of the housing defines a flat region that is configured to define a bypass port at the junction between the outer surface of the housing and a surface of the delivery device to permit air flow into the delivery device.
A cartridge for a delivery device, the cartridge comprising:
- a connection portion configured to be detachably connected to the delivery device, the connection portion including a first end having an outlet, and a first sidewall disposed about the first end defining an outer surface, the outer surface of the connection portion first sidewall comprises a flat region configured to define a bypass port between the connection portion and the delivery device when the cartridge is connected to the delivery device, and
- a base portion, the base portion including a second end, a second sidewall disposed about the second end, and a post extending from the second end in parallel with the second sidewall so that at least a portion of the post is surrounded by the second sidewall,
- wherein the connection portion is engaged with the base portion to define a reservoir between the first end and the second end, and
- the connection portion is moveable relative to the base portion between a first position in which the outlet is open such that fluid communication exists between the reservoir and the exterior of the cartridge, and a second position in which the post is positioned within the outlet so as to close the outlet.
A cartridge and a delivery device:
- the cartridge comprising a housing defining a reservoir and a cartridge outlet, the cartridge outlet configured to permit fluid communication between the reservoir and an exterior of the cartridge,
- the housing forming a junction with the delivery device and an outer surface of the housing defining a flat region defining a bypass port between the outer surface of the housing and the delivery device at the junction to permit air flow into the delivery device.
