Abstract

A nebulizer and a method of breathing using the nebulizer is described. The nebulizer and breathing techniques are capable of delivering medicament into the sinus cavity of a user.

Claims

1. A nebulizer comprising:

a nasal adapter;

a vortex chamber in communication with the nasal adapter;

an outflow tube in communication with the vortex chamber; and

a housing, the housing having a medicine chamber in which the medicine is nebulized in communication with the outflow tube.

2. The nebulizer of claim 1, wherein the nebulizer is capable of delivery of particles sizes ranging from about 2 to about 50 microns,

3. The nebulizer of claim 1, further comprising:

a lid for covering the medicine chamber;

a cartridge capable of insertion into the medicine chamber; and

a nebulizing stem connected to the lid, the stem capable of insertion into the cartridge.

4. A method of delivering a medicament to the nasal cavity and paranasal sinuses comprising:

providing the nebulizer of claim 1; and

performing, using the nebulizer, a controlled particle dispersion breathing technique, wherein the medicament is delivered to the nasal cavity and paranasal sinuses.

5. The method of claim 4, wherein the nebulizer is capable of delivery of particles sizes ranging from about 2 to about 50 microns.

6. The method of claim 4, wherein the medicament is at least one of a treatment for conditions consisting of sinusitis, allergies, rhinitis, migraine headache, influenza, and the common cold.

7. A particle dispersion chamber comprising:

a housing having an external surface and an internal channel; and

a plurality of air outputs communicating with the internal chamber, whereby the air outputs are capable of causing a plurality of nebulized particles to randomly move in a vortex within the internal channel.

8. The particle dispersal chamber of claim 7, wherein the air outputs are positioned randomly along the internal channel of the particle dispersion chamber.

9. The particle dispersion chamber of claim 7, wherein the air output are positioned in a set array along the internal channel of the particle dispersion chamber.

10. The particle dispersion chamber of claim 7, wherein the air outputs are jets.

11. The particle dispersion chamber of claim 7, further comprising an inhaler having a mouthpiece, the mouthpiece associated with the particle dispersion chamber.

12. The particle dispersion chamber of claim 7, further comprising a nasal spray inhaler having an actuator, the actuator associated with the particle dispersion chamber.

13. The particle dispersion chamber of claim 7, further comprising a dry powder inhaler having an mouthpiece, the mouthpiece associated with the particle dispersion chamber.
