Patent ID: 7470267

Claim:
A fluid delivery device, comprising: an electrochemical pump comprising a first electrode, a second electrode, and an anion exchange membrane positioned therebetween, at least one of said electrodes spaced from said anion exchange membrane, wherein the electrochemical pump is capable of transporting water; an electrochemical pump product chamber, wherein the electrochemical pump product chamber is capable of retaining water transported by the electrochemical pump; a displaceable member positioned between the electrochemical pump product chamber and a reservoir, wherein the displaceable member is controllably displaced upon transportation of water from the electrical pump; a reservoir, wherein the reservoir is capable of containing a fluid which is delivered upon displacement of the displaceable member; and a housing for containing the electrochemical pump, the electrochemical pump product chamber, the displaceable member, and the reservoir, said housing configured to allow fluid external to said housing to operably communicate with at least one of said electrodes.
