Abstract

A fluid ejection system (20) comprising a cartridge (24), an ejector (32, 300) and, optionally, a fill station (28) for filling the cartridge with a fluid, such as a vaccine. In some embodiments (52), the cartridge includes a transfer passageway (96) for receiving fluid from the fill station. In other embodiments (200, 400), the cartridge includes a vented fluid reservoir (208, 408) offset from an ejection chamber (224, 420). In yet other embodiments (500, 600), the cartridge includes a vented fluid reservoir chamber (512, 636) inline with the ejection chamber (508, 644). In still other embodiments (700, 1000, 1100), the cartridge includes first and second chambers (728, 736, 1036, 1048, 1136, 1148) initially fluidly sealed from on another by a valve, e.g., either a traveling valve (704, 800, 900, 1200, 1300) or a temporarily stationary valve (1004, 1104).
