Abstract: A medication inhalation apparatus preferably formed of a single, unitary sheet of stock, includes an outer housing, movable between collapsed and expanded states, encompassing a first volume. An inner housing within the outer housing encompasses an inner or second volume. An inhaler opening to the first volume is within a wall of the outer housing at a first location. A mouth opening to the inner volume is within a wall of the outer housing and the inner housing at a second location. A one-way inhalation valve connecting the first volume and the inner volume is within a wall of the inner housing. A one-way exhalation valve connecting the inner volume and the exterior of the outer housing is within a wall of the outer housing and inner housing at a third location. The valve preferably includes an elongated spring body formed of a semi-pliant material with a strength and rigidity providing limited flexibility.

Abstract: A medication inhalation apparatus formed of a single, unitary sheet of stock, includes an outer housing, movable between collapsed and expanded states, encompassing a first volume. An inner barrier within the outer housing delineates a second volume. An inhaler opening to the first volume is within a sidewall of the outer housing at a first location. A mouth opening to the second volume is within a sidewall of the outer housing at a second location. A one-way inhalation valve connecting the first volume and the second volume is formed from a sidewall of the inner barrier. A one-way exhalation valve connecting the second volume and the exterior of the outer housing is formed from a sidewall of the outer housing and inner barrier at a third location. In the expanded state, gas flows from the inhaler to the first volume, the first volume to the second volume, and the second volume to a user's mouth.
