Abstract:
1. An A disposable iontophoretic fluid delivery device comprising: a cationic chamber defining a volume in which to hold a cationic substance, a wall of said chamber having a first passageway permitting migration therethrough by ions; an anionic chamber defining a volume in which to hold an anionic substance, a wall of said anionic chamber having a second passageway permitting migration therethrough by ions, said first and second passageways being oriented and arranged on a surface of a container to enable creation of an ion conducting path, through a cooperating body, of an electrical circuit between said cationic and anionic chambers; a first electromotive cell comprising a mini battery configured to produce a single, approximately square-wave current discharge over the first electromotive cell's working life and comprising first and second poles of opposite electrical sign, said first electromotive cell being disposed in an electron conducting path configured to complete said electrical circuit; and a shunt resistance disposed in parallel with an ion conducting path between said cationic and anionic chambers, said shunt resistance selected to control the delivery of fluid from the iontophoretic fluid delivery device; wherein a quantity of energy from said mini battery is substantially exhausted after delivery of a treatment dose.
