Patent ID: 8651104

Claim:
A dry powder inhaler, comprising: an inlet channel through which air enters the inhaler; a chamber that receives air from the inlet channel, wherein the chamber has a longitudinal axis, and wherein the inlet channel is generally co-axial with the longitudinal axis; a single bead-like actuator disposed within the chamber, wherein the bead-like actuator has an outer surface to which a medicament is adhered; and an outlet channel through which air and the powdered medicament leave the inhaler to be delivered to a patient, wherein the outlet channel is generally co-axial with the longitudinal axis of the chamber; wherein the geometry of the inhaler is such that a flow profile is generated within the chamber that causes the bead-like actuator to oscillate generally co-axial with the longitudinal axis, thus detaching the medicament from the outer surface of the bead-like actuator to be entrained by the air and delivered to the patient through the outlet channel.
