Nebulizer method
View Patent ↗An artificial cigarette, inhaler or other nebulizer device may include a housing, an air passage into the housing, a fog generator chamber within the housing connected to the air passage, a liquid source connected to the fog generating chamber, and a fog generator within the fog generating chamber for receiving liquid from the liquid source and creating an aerosol. The fog generator may be an ultrasonic nebulizer and/or a pneumatic nebulizer.
1. A nebulizer method comprising:
providing a nebulizer apparatus comprising a housing with a distal end and a proximal end, a fog generating chamber within the housing, an aerosol passageway fluidly connecting the proximal end of the housing with the fog generating chamber, a fog chamber valve regulating flow of gas between the aerosol passageway and the fog generating chamber, a liquid source in fluid communication with the fog generating chamber, and a fog generator within the fog generating chamber for receiving liquid from the liquid source and creating an aerosol,
fluidly contacting the air passage with a mouth,
inhaling through the nebulizer apparatus, and
wherein the inhaling activates the fog generator.
2. The method of claim 1 , wherein the fog generator is an ultrasonic nebulizer.
3. The method of claim 2 , wherein the ultrasonic nebulizer comprises a piezoelectric surface on a flat transducer.
4. The method of claim 2 , further comprising powering the ultrasonic nebulizer with a power supply.
5. The method of claim 4 , further comprising dissipating heat within the nebulizer apparatus with one or more heat sinks.
6. The method of claim 1 , wherein the fog generator is a pneumatic nebulizer.
7. The method of claim 6 , wherein the pneumatic nebulizer is a glass frit.
8. The method of claim 7 , further comprising creating a pressure differential across the pneumatic nebulizer with a compressed air supply.
9. The method of claim 1 , further comprising sensing movement of air through the air passage with one or more air flow sensors.
10. The method of claim 9 , further comprising controlling a liquid valve disposed between the liquid source and the fog generating chamber with the one or more air flow sensors.
11. The method of claim 9 , further comprising controlling a compressed air supply for creating a pressure differential across the fog generator with the one or more air flow sensors.
12. The method of claim 9 , further comprising controlling a power supply for powering the fog generator with the one or more air flow sensors.
13. The method of claim 1 , wherein the nebulizer apparatus further comprises a mouthpiece.
14. The method of claim 1 , further comprising preventing large aerosol droplets from exiting the fog generating chamber with a baffle.
15. The method of claim 1 , further comprising exhaling at least partially through the nebulizer apparatus.
16. The method of claim 15 , further comprising closing the fog generating chamber during exhalation into the nebulizer apparatus with a fog chamber valve.
17. The method of claim 15 , further comprising directing exhaled air out of the nebulizer apparatus with one or more aerosol exits connected to the air passage.
18. The method of claim 17 , further comprising closing the one or more aerosol exits during inhalation and opening the one or more aerosol exits during exhalation with one or more valves.
19. The method of claim 1 , wherein the liquid comprises a pharmacological active agent.
