Patent ID: 6886557

Claim:
An inhalation device comprising: an inhalation chamber; control electronics having an information storage portion; first and second microfluidic aerosol generators governed by the control electronics, the first and second microfluidic aerosol generators capable of contemporaneously emitting droplets of a first material and a second material, respectively, into the inhalation chamber to form a single inhalable composition, wherein the first and second materials are pharmacologically different from each other; a reservoir in fluid communication with the first and second microfluidic aerosol generators and including a plurality of chambers with a first chamber and a second chamber in fluid communication, respectively, with the first and second aerosol generators, the first chamber configured to contain the first material and the second chamber configured to contain the second material; wherein the information storage portion stores a regimen of doses to enable the control electronics to direct quantities of the first and second materials to be emitted with each activation of the inhalation device as the single inhalable composition, and to direct the quantities of the first and second pharmacologically different materials to vary with respect to each other to alter the concentration of the first material relative to the second material in the single inhalable composition over the regimen of doses.
