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.

A nebulizer device for use with a source of oxygen flow, a source of atmospheric gas, a fluid supply container and respiratory ducting equipment leading to a patient, comprising: a housing having means for coupling to said fluid supply container, a mixing chamber therein and an atmosphere inlet port opening into said mixing chamber; an oxygen duct having means for coupling to said source of oxygen flow, said oxygen duct having an oxygen outlet disposed in said mixing chamber; means for conveying fluid from said fluid supply container to said mixing chamber proximate said oxygen outlet; an atmosphere restricting gate movably mounted on said housing so as to move in a first direction and a second direction nonparallel to said first direction, said atmosphere restricting gate configured to adjustably close said atmosphere inlet port and thereby selectively restrict air flow therethrough as said atmosphere restricting gate is moved in said first direction an in said second direction; an oxygen restricting gate movably mounted on said oxygen duct so as to move in at least said first direction, said oxygen restricting gate coupled to said atmosphere restricting gate and configured to adjustably close said oxygen outlet and thereby selectively restrict oxygen flow therethrough as said atmosphere restricting gate is moved in said first direction, and said oxygen restricting gate coupled to said atmosphere restricting gate so as to not vary restriction of oxygen flow through said oxygen outlet as said atmosphere restricting gate is moved in said second direction.
