Abstract

The disclosed inhalation apparatus is suited for easily administering aerosol medication via a metered dose pressurized canister. The apparatus has a collapsible tubular body comprised of axially nested rigid pieces including end pieces with opposite connections respectively for directing spray from the canister axially through the tubular body cavity from one connection toward the other connection serving as the user's tubular mouthpiece. The tubular body can be axially shifted between an expanded operational position of maximum body cavity volume and maximum separation between the end pieces and a collapsed storage position of minimum separation where the rigid pieces are nested together. The end pieces have end plates of substantially equal size with peripheries suited to be gripped by the user, and a tubular flange projected off of one end plate that cooperates in proximity with structure of the other end plate in the collapsed position, providing a protective housing overlying the rigid pieces when collapsed.
