Aerosol therapy device with high frequency delivery

摘要

The present invention relates to an aerosol therapy device, wherein an aerosol is generated in an aerosol generating device and is supplied through a nosepiece to a patient's nasal cavities via a single pulsed main aerosol flow.

主权项

1. An aerosol therapy device for delivery of an active agent to the paranasal sinuses of a patient comprising:
(a) an aqueous drug reservoir, said aqueous drug reservoir being connected to (b) an aerosol generator for the generation of aerosol particles, said aerosol generator being connected to (c) an air-flow supply device, said air-flow supply device producing a single airflow to carry said aerosol particles of (b), wherein said single airflow consists of a pulsating flow of air and comprises a pressure field produced by a pulsed pressure wave, wherein said pulsating airflow pulsates at a frequency from about 150 Hz to about 6000 Hz; and (d) a nosepiece to direct said single airflow comprising aerosol particles of (c) into one of the two alae of the nose of the patient wherein said nose piece is a twin-port nose piece, whereby said aerosol therapy device delivers aerosol particles comprising an active agent to the paranasal sinuses of the patient.
