Patent ID: 7819115

Claim:
An inhaler system, comprising: an inhalation/exhalation structure including an inhalation/exhalation orifice; a medicament supply system including a medicament ejector disposed in fluidic communication with the inhalation/exhalation orifice, wherein the medicament supply system controllably ejects medicament droplets from the medicament ejector; and a flow control system in fluidic communication with the medicament ejector, the flow control system configured to provide an airflow substantially across a face of the medicament ejector wherein the airflow passes first through an inhalation valve and then across the face of the medicament ejector, wherein the airflow is oriented to entrain the medicament droplets and then pass the medicament droplets to the inhalation/exhalation orifice when a patient applies an in-breath to the inhalation/exhalation structure, and wherein the flow control system is configured to impede a flow of air from the inhalation/exhalation orifice to the medicament ejector when the patient applies an out-breath into the inhalation/exhalation structure.
