ABSTRACT:
A nebulizer device having an atmosphere adjusting collar both slidably and rotatably mounted on the housing so as to adjust restriction of atmosphere inlet ports on the housing. An additional high oxygen port on the nebulizing nozzle is restricted by a flow rate adjusting collar. The flow rate adjusting collar is coupled to the atmosphere adjusting collar so as to maintain rate of flow as the atmospheric inlet is adjusted, but the atmospheric inlet is automatically adjusted as the oxygen flow rate is adjusted. An atmosphere entraining valve located downstream of the nebulizer housing provides additional entrainment of atmosphere to further reduce the fraction of inspired oxygen in the humidified air.
