The nebuliser has a driving gas pathway through a nebulising section and the gas pathway includes a pneumatic control valve operable between an open configuration in which gas is able to flow from a supply inlet through the nebulising section to create an aerosol and to an airway with outlet for onward delivery and a closed configuration in which gas flow to the outlet is stopped. With the nebuliser drugs in an aerosol form can be delivered to a patient during the inhalation phase only and earlier in the inhalation cycle than can be achieved using conventional pneumatically activated nebulisers. |
