| 摘要 | A nasal delivery device for and method of delivering substance to a nasal cavity of a subject, the delivery device comprising: a container-receiving unit comprising a container chamber for receiving a substance-containing container which contains substance to be delivered to the nasal cavity of the subject, the container chamber including an inlet and an outlet; a nosepiece unit including a nosepiece for fitting to a nasal cavity of the subject and being in fluid communication with the outlet of the container chamber; a mouthpiece unit including a mouthpiece in fluid communication with the inlet of the container chamber and through which the subject in use exhales, such as to entrain substance from the container and deliver the same through the nosepiece; and moisture-mitigation means for mitigating an effect of moisture in an exhaled breath on the entrainment of substance from the container, which means are provided, for example, by providing the container in a replaceable container-containing member, by a pressure-sensitive valve which normally closes the fluid connection between the container chamber and the mouthpiece, and a temperature regulator upstream of the container chamber. | ||
