Methods and apparatus for delivering aerosolized medication
摘要
A metered dose inhaler (10) for use with a pressurized aerosol canister (18) includes a housing (12) defining a conduit (16) with a mouthpiece (56), and an actuator (26) with a nozzle discharge orifice (30) arranged to discharge aerosol into the conduit. An air tube (34) is arranged within the conduit with an inlet (38) of the air tube formed in the conduit wall (74) and an outlet (36) of the air tube in opposing relationship with the nozzle orifice. Inhalation through the mouthpiece causes air to be drawn into the inlet and flow out of the outlet of the air tube to form an air jet which impinges on an oppositely moving aerosol plume from the orifice.
