Abstract
A collapsible inhalation valve is provided for administering asthmatic medication or the like. The valve comprises an upright cylindrical air chamber adapted to be held in the hand. A reciprocating member holds a pressurized cartridge of medication for reciprocation between storage position substantially within the air chamber and raised using position substantially exterior to the air chamber. A mouthpiece is pivoted on the air chamber and is movable between storage position substantially within the air chamber and using position projecting from the air chamber. A one-way valve is provided at the bottom of the air chamber to allow movement of air into the air chamber while preventing movement of medication out of the air chamber. Another one-way valve is provided at the entrance to the mouthpiece permitting inhaling of misted medication, but preventing exhaling into the air chamber.
