1. A nebulizer for delivering a mist of liquid, comprising:
- a housing;
a reservoir disposed internally to the housing for containing a liquid to be nebulized by the nebulizer;
a monolithic nebulizer tube having;
a gas channel having a first end for receiving a compressed gas and a second end for expelling compressed gas and nebulized liquid, the gas channel extending from a first end to a second end of the nebulizer tube, anda liquid feed channel having a first end in fluid communication with the reservoir for receiving the liquid from the reservoir and having a second end in fluid communication with the gas channel, whereby application of compressed gas to the first end of the gas channel creates a siphon in the liquid feed channel to draw liquid into the feed channel and to expel the liquid and compressed gas from the second end of the nebulizer tube; and
a tortuous passageway disposed within the housing between second end of the gas channel and an exit port of the nebulizer for directing the flow of nebulized mist therethrough to the exit port.

1. A nebulizer for delivering a mist of liquid, comprising:
-
a housing; a reservoir disposed internally to the housing for containing a liquid to be nebulized by the nebulizer; a monolithic nebulizer tube having; a gas channel having a first end for receiving a compressed gas and a second end for expelling compressed gas and nebulized liquid, the gas channel extending from a first end to a second end of the nebulizer tube, and a liquid feed channel having a first end in fluid communication with the reservoir for receiving the liquid from the reservoir and having a second end in fluid communication with the gas channel, whereby application of compressed gas to the first end of the gas channel creates a siphon in the liquid feed channel to draw liquid into the feed channel and to expel the liquid and compressed gas from the second end of the nebulizer tube; and a tortuous passageway disposed within the housing between second end of the gas channel and an exit port of the nebulizer for directing the flow of nebulized mist therethrough to the exit port. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)

9. A nebulizer for delivering a mist of liquid, comprising:
-
a housing; a reservoir disposed internally to the housing for containing a liquid to be nebulized by the nebulizer; and a monolithic nebulizer tube having; a gas channel having a first end for receiving compressed gas and a second end for expelling compressed gas, the gas channel extending from a first end to a second end of the nebulizer tube, and a liquid feed channel having a first end in fluid communication with the reservoir for receiving the liquid from the reservoir and having an annular passageway at a second end of the feed channel, the annular passageway disposed about the second gas channel end, whereby application of compressed gas to the first end of the gas channel creates a siphon in the liquid feed channel to draw liquid into the feed channel and to expel the liquid and compressed gas from the second end of the feed channel.

51. A nebulizer for delivering a mist of liquid, comprising:
-
a housing having an inlet port for receiving compressed gas and an exit port for delivering a mist of nebulized liquid; a reservoir disposed internally to the housing for containing a liquid to be nebulized by the nebulizer; a nebulizer tube in fluid communication with the liquid having an outlet from which the nebulized mist is provided, the outlet end disposed internally to the housing; and a tortuous passageway disposed within the housing between outlet end of the nebulizer tube and the exit port of the nebulizer for directing the flow of nebulized mist therethrough to the exit port. - View Dependent Claims (52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62)

63. A two-piece nebulizer for delivering a mist of liquid, comprising:
-
a two-piece housing having separate first and second housing portions; a reservoir monolithic to the housing for containing liquid to be nebulized by the nebulizer; and a nebulizer tube monolithic to the housing having; a gas channel having a first end for receiving compressed gas and a second end for expelling compressed gas and nebulized liquid, the gas channel extending from a first end to a second end of the nebulizer tube, a liquid feed channel having a first end in fluid communication with the reservoir for receiving liquid from the reservoir and having a second end in fluid communication with the gas channel, whereby application of compressed gas to the first end of the gas channel creates a siphon in the liquid feed channel to draw liquid into the feed channel and to expel the liquid along with compressed gas from the second end of the nebulizer tube. - View Dependent Claims (64, 65, 66, 67, 68, 69)
