A breath actuated dispenser there-shown has a generally L-shaped hollow body 1 with a mouthpiece 2. An aerosol drug can 3 is mounted in the body. The can has a dispensing spout 4, which engages a receptor moulding 5 incorporating a living hinge 11, a movable outlet member 8 and a kink valve 9. A flap member 31 is pivotally mounted between the can and the receptor moulding. Breathing in through the dispenser by the patient will cause the flap to be drawn down against its spring 34. The outlet member is then tipped down by the spring 37 to point out of the mouthpiece 2, whence the dose is dispensed by opening of the kink valve.

An aerosol generator such as a hand-held inhaler and method of delivering aerosol to a user inhaling on an outlet of a mouthpiece when a pressure drop is detected within the mouthpiece. A medicated fluid passing through a capillary passage is heated sufficiently to vaporize the fluid and form the aerosol by condensation of the vaporized fluid as it admixes with air. Air is supplied to the mouthpiece through an air passage which is initially closed during detection of the pressure drop. A metering chamber allows consistent delivery of precise doses of fluid to the capillary passage. The pressure drop is detected before air is supplied to the mouthpiece with the result that the aerosol can be quickly delivered to the user as the user begins to inhale on the mouthpiece. The quick delivery of aerosol provides more efficient use of the user's lung capacity.

A device and method for delivering a therapeutic drug to a patient in the form of an aerosol includes a heat generating chamber and an aerosol forming chamber separated by a heat conductor. A heating element is disposed within the heat generating chamber in heat conducting relation with the heat conductor. A substrate having a therapeutic drug and an aerosol forming agent deposited thereon is disposed within the aerosol forming chamber in heat conducting relation with the heat conductor. The heating element ignites a fuel source consisting essentially of a combustible liquefied gas to generate heat that is conducted to the heat conductor and then to the substrate via the heat conductor. The heat generated by the heating element activates the aerosol forming agent to volatilize the therapeutic drug into an aerosol drug contained within the aerosol forming chamber and made available to be inhaled by the patient.

An electronic gas flow triggering circuit for use in an aerosol drug dispensing device has a voltage source and a self-nulling circuit to which voltage is supplied from the voltage source. A hot wire anemometer filament forms a component of the bridge circuit which is adapted to maintain a constant resistance of the anemometer filament, the bridge drive voltage being dependent upon the gas flow across the anemometer filament. A comparator compares the bridge output voltage with a reference voltage and provides a triggering signal to operate the device if the bridge drive voltage is greater than the reference voltage.
