Abstract
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.
