Abstract: A nasal delivery device for and method of delivering substance to a nasal airway of a subject, the delivery device comprising: a nosepiece for fitting to a nasal cavity of a subject; a mouthpiece into which the subject in use exhales; a delivery unit, which comprises an actuation part which is manually displaceable to actuate the delivery unit to deliver substance from the nosepiece; and a valve assembly which is fluidly connected to the nosepiece and the mouthpiece, wherein the valve assembly comprises a body element and a valve element which is movably disposed to the body element between closed and open configurations by manual displacement of the actuation part of the delivery unit to provide for an air flow through the nosepiece simultaneously with delivery of substance.

Abstract: A nasal delivery device for and method of delivering substance to a nasal airway of a subject, the delivery device comprising: a nosepiece (117) for fitting to a nasal cavity of a subject; a mouthpiece (119) into which the subject in use exhales; a delivery unit, which comprises an actuation part which is manually displaceable to actuate the delivery unit to deliver substance from the nosepiece; and a valve assembly (127) which is fluidly connected to the nosepiece and the mouthpiece, wherein the valve assembly comprises a body element (128) and a valve element (131) which is movably disposed to the body element between closed and open configurations by manual displacement of the actuation part of the delivery unit to provide for an air flow through the nosepiece simultaneously with delivery of substance.

Abstract: A nasal delivery device for delivering substance to a nasal cavity of a subject comprises: a housing (15); a nosepiece (17) for fitting to a nasal cavity of the subject; a mouthpiece (19) through which the subject in use exhales; and a flexible coupling (20) which couples the mouthpiece to the housing, wherein the flexible coupling provides for asymmetric translation of the mouthpiece relative to the nosepiece.
