GAS GENERATION DISPENSER APPARATUS AND METHOD FOR ON-DEMAND FLUID DELIVERY

摘要

An on-demand fluid dispenser (30) to dispense fluid (63) in response to gas generation by a gas cell (48). The on-demand fluid dispenser (30) includes an expandable gas chamber (51), a fluid chamber (57), and an on-demand gas cell (48). The expandable gas chamber (51) includes a moveable plunger forming a wall of the expandable gas chamber. The moveable plunger also forms a wall (54) of the fluid chamber (57). The on-demand gas cell (48) is configured to generate the gas on demand. The on-demand gas cell (48) is also configured to direct the gas to the expandable gas chamber (51) to expand the expandable gas chamber (51). Expansion of the expandable gas chamber (51) moves the moveable plunger (54) to reduce a volume of the fluid chamber (57) and to dispense an amount of fluid (63) from the fluid chamber (57).
