Aerosol devices and methods for inhaling a substance and uses thereof
View Patent ↗Devices, cartridges, and method are described herein for emulating smoking wherein a device generates an aerosol for inhalation by a subject by heating a viscous material that can have a tactile response in the mouth or respiratory tract, while reducing Hoffman analytes and mutagenic compounds delivered to the user as compared to a common tobacco cigarette.
1. A method of delivering an aerosol to a subject, the method comprising:
a) deploying an aerosol generating device comprising a heater and a vaporizable material in a vaporization chamber, wherein the vaporizable material comprises a tobacco product and an aerosol-forming medium, wherein the tobacco product comprises fine pieces of tobacco, wherein the fine pieces of tobacco are less than 2 mm in diameter, and wherein the aerosol-forming medium comprises glycerin or propylene glycol;
b) heating the vaporizable material in the vaporization chamber with the heater of the device to a target temperature, wherein the target temperature is 100° C. to 180° C.;
c) generating the aerosol in the vaporization chamber, wherein the aerosol contains at least 70% less Hoffman analytes than a common tobacco cigarette; and
d) delivering the aerosol directly to the subject for inhalation.
2. The method of claim 1 , wherein the Hoffman analytes include: ammonia, aminonaphthalenes, benzopyrene, formaldehyde, acetaldehyde, acetone, methylethylketone, butyraldehyde, hydrogen cyanide, nitrous oxides, tobacco-specific nitrosamines (TSNAs), pyridine, quinoline, hydroquinone, phenol, cresols, carbon monoxide, 1,3-butadiene, isoprene, acrylonitrile, benzene, toluene, and styrene.
3. The method of claim 1 , wherein the target temperature is 100° C. to 150° C.
4. The method of claim 1 , wherein the target temperature is about 150° C.
5. The method of claim 1 , wherein the aerosol contains at least about 80% less Hoffman analytes than a common tobacco cigarette.
6. The method of claim 1 , wherein the aerosol contains at least about 90% less Hoffman analytes than a common tobacco cigarette.
7. The method of claim 1 , wherein the aerosol-forming medium comprises glycerine and propylene glycol.
8. The method of claim 1 , wherein the vaporization chamber and heater are within a sealed cartridge, and wherein deploying the aerosol generating device comprises attaching the cartridge to a reusable portion of the device.
9. The method of claim 8 , further comprising removing the cartridge from the reusable portion when the vaporizable material is depleted.
10. The method of claim 1 , wherein the vaporizable material is a fluidic vaporizable material.
11. The method of claim 1 , wherein the tobacco product comprises fine pieces of tobacco, wherein the fine pieces of tobacco are less than 1 mm in diameter.
12. The method of claim 1 , wherein the aerosol comprises particles less than about 2 microns in diameter.
13. The method of claim 1 , wherein the aerosol-forming medium further comprises a natural or an artificial flavorant.
14. The method of claim 1 , comprising a natural flavorant, wherein the natural flavorant comprises lemon flavor.
15. An aerosol generating device comprising:
a heater; and
a vaporization chamber comprising a vaporizable material that comprises a tobacco product and an aerosol-forming medium, wherein the tobacco product comprises fine pieces of tobacco, wherein the fine pieces of tobacco are less than 2 mm in diameter, and wherein the aerosol-forming medium comprises glycerine or propylene glycol,
wherein the device generates an aerosol in the vaporization chamber upon heating the vaporizable material to a target temperature, wherein the target temperature is 100° C. to 180° C.,
wherein the aerosol in the vaporization chamber is deliverable directly to a user following generation, and
wherein the aerosol contains at least 70% less Hoffman analytes than a common tobacco cigarette.
16. The device of claim 15 , wherein the Hoffman analytes include: ammonia, aminonaphthalenes, benzopyrene, formaldehyde, acetaldehyde, acetone, methylethylketone, butyraldehyde, hydrogen cyanide, nitrous oxides, tobacco-specific nitrosamines (TSNAs), pyridine, quinoline, hydroquinone, phenol, cresols, carbon monoxide, 1,3-butadiene, isoprene, acrylonitrile, benzene, toluene, and styrene.
17. The device of claim 15 , wherein the target temperature is 100° C. to 150° C.
18. The device of claim 15 , wherein the target temperature is about 150° C.
19. The device of claim 15 , wherein the aerosol contains at least about 80% less Hoffman analytes than a common tobacco cigarette.
20. The device of claim 15 , wherein the aerosol contains at least about 90% less Hoffman analytes than a common tobacco cigarette.
21. The device of claim 15 , wherein the aerosol-forming medium comprises glycerine and propylene glycol.
22. The device of claim 15 , wherein the vaporization chamber and heater are within a sealed cartridge.
23. The device of claim 22 , wherein the cartridge is configured to be removed from a reusable portion of the device when the vaporizable material is depleted.
24. The method of claim 15 , wherein the vaporizable material is a fluidic vaporizable material.
25. A method of delivering an aerosol to a subject, the method comprising:
a) deploying an aerosol generating device comprising a heater and a vaporizable material in a vaporization chamber, wherein the vaporizable material comprises a tobacco product and an aerosol-forming medium, wherein the tobacco product comprises fine pieces of tobacco, wherein the fine pieces of tobacco are from 1 mm to 2 mm in diameter, and wherein the aerosol-forming medium comprises glycerin or propylene glycol;
b) heating the vaporizable material in the vaporization chamber with the heater of the device to a target temperature, wherein the target temperature is 100° C. to 180° C.;
c) generating the aerosol in the vaporization chamber, wherein the aerosol contains at least 70% less Hoffman analytes than a common tobacco cigarette; and
d) delivering the aerosol directly to the subject for inhalation.
