Abstract
The present invention is a dry powder inhaler that is operable to deliver a dry powder medication to the lungs of a patient without the use of a propellant. The inhaler device is a tubular shell with an opening at either end of the shell and an air passageway therethrough, a medication storage chamber, an axially moved air inlet closure member covering the air inlet opening(s), and a slidable medication dosing tray attached to the closure member. In use, the air inlet closure member is pulled in a direction away from the user while the patient inhales, causing the simultaneous introduction and flow of air through the air passageway, and dispersement of a dosage of the medication into the air passageway. The patient then inhales the air/medication mix which passes into the lungs.
