Microfluidic Delivery Cartridges for Use with Microfluidic Delivery Devices

摘要

A cartridge releasably connectable with a housing of a microfluidic delivery device is provided. The cartridge has a reservoir for receiving the fluid composition, and a microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in a horizontal direction or downward relative to the horizontal direction. The cartridge also includes an air flow channel disposed below the reservoir. An air flow channel extends from the fan to the air outlet. The air flow channel includes a first region disposed adjacent the fan, a second region disposed adjacent the air outlet, and a third region connecting the first region and the second region. At least the second region is inclined upwardly to the air outlet relative to the horizontal.
