BREATH ACTUATED NEBULIZER WITH VALVE ASSEMBLY HAVING A RELIEF PISTON |
摘要 |
A breath actuated nebulizer for efficiently and reliably delivering aerosolized liquid to an inhaling patient is disclosed. The nebulizer includes a valve assembly having an actuator piston for quickly responding to an inhalation and beginning the nebulization process, and a relief piston to lower the inhalation effort required of the inhaling patient. Also provided is a method of providing breath actuated nebulization including the steps of moving an actuator piston connected to a diverter so that the diverter reaches a nebulizing position during an initial period of inhalation, and moving a relief valve to allow a greater flow of air, and thereby reduce inhalation effort, after the initial period of inhalation. |
