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.

Claims

1. A nasal insert comprising:

a pair of dispenser devices adapted to be positioned within the nasal passages, each of said devices being formed of a resilient, cylindrical wall member;

a connecting strip extending between said cylindrical members and adapted to bridge across the septum;

an absorptive plug located within each of said cylindrical members and adapted to be saturated with a medicament;

a sidewall of each of said cylindrical members being established by a continuous cylindrical surface, an access opening being formed in a portion of said surface for receiving said plug;

a lower end of each of said cylindrical members including a filter element; and

an upper end of each of said cylindrical members including a means for retaining said plug in said member while permitting axial air flow.

2. The insert of claim 1, wherein said absorptive plug is washer shaped to enable axial air flow through its central aperture.

3. The insert of claim 1, wherein said retaining means includes a pair of mutually orthogonal cross members extending radially within said cylindrical member.

4. The insert of claim 1, including a parameter probe means positioned within an air flow path in at least one of said cylindrical members, means for dispensing a medicament within said nasal passages and means responsive to said probe means for controlling said dispensing means.

5. The insert of claim 1, including means for storing a medicament;

nozzle means adjacent said retaining means of at least one of said cylindrical members for dispensing medicament into an air flow path within said member; and

means for controlling said nozzle means to dispense predetermined quantities of the medicament.

6. The insert of claim 1, wherein said approximately cylindrical members each has an elliptical radial cross section, the major and minor axes of said members corresponding to the configuration of the nasal passage.

7. A nasal insert comprising:

a pair of dispenser devices adapted to be positioned with the nasal passages, each of said devices being formed of a resilient, cylindrical wall member;

a connecting strip extending between said cylindrical members and adapted to bridge across the septum;

a medicated plug located within each of said cylindrical members for dispensing a medication within said nasal passages;

a sidewall of each of said cylindrical members being established by a continuous cylindrical surface, an access opening being formed in a portion of said surface for receiving said plug;

a lower end of each of said cylindrical members including a filter element; and

an upper end of each of said cylindrical members including means for retaining said plug in said member while permitting axial air flow.

8. The insert of claim 7, wherein said plug is washer shaped.
