    摘要： 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.

    摘要翻译： 一种用于将液体引导到患者体内或身体上的一次性雾化装置。 雾化装置包括用于保持液体的容器和设置在容器中的液体入口管。 雾化喷嘴与液体入口管连通。 气体入口管与喷嘴连通并且可附接到压缩气体源。 雾化装置包括与气体入口管相邻的触发阀系统，用于将压缩气体从气体入口管控制释放到雾化喷嘴。 触发阀系统包括定位在由具有盖的阀壳体围绕的针支撑件中的针阀。 针支撑件可移动地与盖接合，用于将针阀保持在阀壳体内，并且针阀朝向帽弹性偏压。 阀壳体具有用于将管线压力降低到可接受水平的压力释放端口。 当针支撑件被操作者向内压下时，针阀将气体从气体入口管释放到喷嘴中，从而将液体从容器中排出到喷嘴中，使得当从喷嘴排出时液体被雾化。
