ABSTRACT:
An intranasal device for filtering nasal air and dispensing medication to be inhaled comprises a pair of approximately cylindrical resilient containers joined together by a bridging member. The containers are adapted to be positioned within the nasal passages with the bridging member extending across the septum. The lower end of each container is formed of a filter material and a washer shaped plug saturated with a medicament is located within each container downstream of the filter. The washer shaped absorptive plug is conveniently inserted into and removed from each container through an access opening formed in the sidewall of the container. The plug is retained within each container at the end by a pair of cross members which permit axial flow-through of air. The device may be provided with at least one temperature sensor or other measurement probe to monitor characteristics of air flow within the nasal passages. The device may further be provided with at least one nozzle to dispense an antibiotic or other substance in addition to the medicament into the nasal air flow.
