Claim:
A medical aerosol delivery device comprised of an actuator for a metered dose inhaler, said actuator having an inlet passage into which a pressurized medication canister is placed, said canister having a base surface thereby situated just outside of said inlet passage, said actuator having an outlet passage through which said medical aerosol flows upon actuation of said canister, said base surface and said inlet passage being covered by an actuator cap, said actuator cap obstructing the flow of air through said inlet passage when said actuator cap contacts said base surface, said actuator cap having a hole centered over said base surface, said hole connected to a mouthpiece such that upon lifting of said actuator cap from said base surface air is allowed to flow through said inlet passage and said hole and said mouthpiece, said outlet passage having a flexible bag chamber air tightly sealed around said outlet passage such that upon inflation of said bag chamber, said medical aerosol flows into said bag chamber upon actuation of said canister thereby allowing subsequent withdrawal by inhalation of a human subject of a portion of said aerosol from said chamber via said outlet passage and then said inlet passage and then said hole and then said mouthpiece.
