Hand-held inhalable vapor producing device and method
Described herein are systems, devices, and methods for generating and delivering an inhalable vapor or aerosol. In some embodiments, the systems, devices, and methods described herein are used to generate and deliver a vapor or aerosol containing tobacco for use in, for example, traditional smoking or, for example, to deliver a smoking cessation therapy. In some embodiments, the systems, devices, and methods described herein are used for generating and delivering a vapor or aerosol comprising a medicament. For example, in some embodiments, the systems, devices, and methods described herein are used to deliver an inhalable medicament to the lungs of a patient.
1. A hand-held inhalable vapor producing device comprising:
a plate that receives a liquid;
a thermal valve that controls delivery of the liquid to the plate, the thermal valve having a first conformation that prevents delivery of the liquid to the plate and a second conformation that enables delivery of the liquid to the plate; and
a heat source that applies heat to the thermal valve and the plate.
2. The hand-held inhalable vapor producing device of claim 1 , wherein the plate comprises a metal and/or a ceramic.
3. The hand-held inhalable vapor producing device of claim 1 , wherein application of heat to the thermal valve by the heat source changes a conformation of the thermal valve from the first conformation to the second conformation.
4. The hand-held inhalable vapor producing device of claim 1 , wherein application of heat to the plate by the heat source vaporizes the liquid received by the plate.
5. The hand-held inhalable vapor producing device of claim 1 , wherein the heat source selectively applies heat to the plate and/or the thermal valve.
6. The hand-held inhalable vapor producing device of claim 1 , wherein the heat source comprises a light source.
7. The hand-held inhalable vapor producing device of claim 6 , wherein the light source comprises a laser.
8. The hand-held inhalable vapor producing device of claim 1 , further comprising:
a cartridge carrying a volume of the liquid.
9. The hand-held inhalable vapor producing device of claim 8 , wherein the cartridge is removable from a remainder of the hand-held inhalable vapor producing device.
10. The hand-held inhalable vapor producing device of claim 8 , wherein the cartridge advances the liquid to the plate when the thermal valve is in the second conformation.
11. The hand-held inhalable vapor producing device of claim 10 , wherein the cartridge includes an ejector that advances the liquid to the plate when the thermal valve is in the second conformation.
12. The hand-held inhalable vapor producing device of claim 1 , further comprising:
a channel positioned to receive the liquid, the thermal valve being positioned to control a flow of the liquid into and/or through the channel.
13. The hand-held inhalable vapor producing device of claim 12 , wherein the channel advances the liquid to the plate by capillary action.
14. The hand-held inhalable vapor producing device of claim 12 , wherein the channel includes a first end that receives the liquid from a source and a second end opposite from the first end, adjacent to the plate, that widens into a reservoir from which the plate receives the liquid.
15. A method for delivering an inhalable vapor, comprising:
heating a thermal valve with a heat source to enable a liquid to be delivered pores-e plate; and
heating the plate with the heat source to vaporize the liquid for inhalation by a subject.
16. The method of claim 15 , wherein heating the thermal valve comprises changing a conformation of the thermal valve from a first conformation that prevents the liquid from being delivered to the plate to a second conformation that enables the liquid to be delivered to the plate.
17. The method of claim 15 , wherein heating the thermal valve and heating the plate occur selectively.
18. The method of claim 15 , wherein:
heating the thermal valve comprises directing light onto the thermal valve; and
heating the plate comprises directing the light onto the plate.
19. The method of claim 18 , wherein:
heating the thermal valve comprises directing a laser onto the thermal valve; and
heating the plate comprises directing the laser onto the plate.
20. The method of claim 15 , wherein heating the plate with the heat source to vaporize the liquid comprises heating the plate to vaporize a medicament for inhalation by the subject.
