A disposable atomizer device for directing a liquid into or on the body of a patient. The atomizer device includes a container for holding a liquid, and a liquid inlet tube disposed in the container. An atomizing nozzle is in communication with the liquid inlet tube. A gas inlet tube is in communication with the nozzle and is attachable to a source of compressed gas. The atomizer device includes a trigger valve system adjacent to the gas inlet tube for providing controlled release of compressed gas from the gas inlet tube to the atomizing nozzle. The trigger valve system includes a needle valve positioned in a needle support surrounded by a valve housing with a cap. The needle support is movably engaged with the cap for retaining the needle valve within the valve housing, and the needle valve is resiliently biased toward the cap. The valve housing has a pressure relief port for reducing line pressure to an acceptable level. When the needle support is depressed inwardly by an operator, the needle valve releases compressed gas from the gas inlet tube into the nozzle, thereby withdrawing the liquid from the container into the nozzle such that the liquid is atomized when discharged from the nozzle.

[ What is claimed and desired to be secured by United States Letters Patent is:] [1.] An atomizer device, comprising:(a) means for holding a liquid;(b) an atomizing nozzle in communication with the means for holding a liquid and a gas outlet tube; and(c) a trigger valve system for providing controlled release of compressed gas to the atomizing nozzle, the trigger valve system including a tapered needle valve positioned in a needle support surrounded by a valve housing with a cap, the needle valve slidably disposed in a valve channel in the valve housing and in substantially coaxial alignment with the gas outlet tube the valve housing having a pressure relief port in communication with the valve channel, the needle support being movably engaged with the cap for retaining the needle valve within the valve housing, the needle valve being resiliently biased toward the cap;wherein when the needle support is depressed inwardly, the needle support seals the pressure relief port while the needle valve releases the compressed gas to flow through the valve channel into the gas outlet tube and to the atomizing nozzle, thereby withdrawing the liquid into the atomizing nozzle such that the liquid is atomized when mixed with the compressed gas in the atomizing nozzle.
