Abstract:
1. An inhalation airflow regulation device suitable for use with one or more inhaler components, said inhalation airflow regulation device comprising: a tubular member having a first end, an opposite second end, and an air flow cross-sectional area between said first end and said opposite second end; an air outlet positioned proximate said first end; a first air inlet positioned proximate said opposite second end; an air flow regulating member positioned along said tubular member, said air flow regulating member comprising one or more coplanar sheets of material (i) positioned at a first location within said tubular member, (ii) secured to said tubular member so as to block a portion, but not all, of said air flow cross-sectional area so as to allow two-way air flow thru said tubular member at the first location, and (iii) secured to said tubular member so that at least a portion of said one or more coplanar sheets of material moves toward said first end within said tubular member in response to a threshold amount of an inhalation force applied thereon; and a medication inlet positioned along said tubular member between said air outlet and said first air inlet; said air flow regulating member being positioned along said tubular member between said medication inlet and said first air inlet so as to regulate air flow that passes thru said tubular member and by said medication inlet.
