SELECTIVELY ACTUATED FLUID DISPENSER

摘要

An apparatus (10) includes a selectively actuated fluid system having a plurality of selected fluid reservoirs (122, 124), for example replaceable cartridge-type fluid reservoirs. A first subset (120) of the reservoirs (122) can be selectively actuated to dispense an individual fluid from the selected reservoir (122). A second subset (130) of the reservoirs (124) can be simultaneously actuated to dispense two or more fluids in mixed form.
