Abstract (en)
[origin: WO2020198736A1] 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. A first separation is perpendicular to the elongate axis of the spring body, and extends from a first edge of the spring body across at least a portion of a width of the spring body. A second separation perpendicular to the elongate axis of the spring body extends from a second edge of the spring body across at least a portion of the width of the spring body.
