The nebulizer of claim 1, wherein the fluid reservoir holds a volume of fluid between about 1 ml and about 10 ml.ġ0. The nebulizer of claim 5, wherein the predetermined expiratory pressure is in a range of about 10 cm H 2O to about 30 cm H 2O when the gate is in the first channel and the predetermined expiratory pressure is less than about 10 cm H 2O when the gate is in the second channel.ĩ. The nebulizer of claim 6, wherein the first face of the flutter valve has an upper edge with a lip and a lower beveled edge.Ĩ. The nebulizer of claim 5, wherein the flutter valve has a first face and a second face angled relative to the first face, and wherein the first face is positioned over the second channel and the second face is positioned over the first channel.ħ. The nebulizer of claim 1, wherein the aerosol delivery channel has a divider and a gate, the divider positioned so the aerosol delivery channel comprises a first channel and a second channel and the gate positionable between the first channel and the second channel to selectively direct the fluid into one of the first channel and the second channel.Ħ. The nebulizer of claim 3, further comprising an arm connected to the valve switch and extending at least partially into the aerosol delivery channel to limit the movement of the flutter valve from the closed position to the open position.ĥ. The nebulizer of claim 1, further comprising a valve switch supported by the body and operably connected to the flutter valve to adjust the predetermined expiratory pressure necessary to open the flutter valve.Ĥ. The nebulizer of claim 1, wherein the flutter valve is pivotally connected to the body and oscillates between the closed position and open position when the fluid is flowing through the aerosol delivery channel toward the second end of the body.ģ. A nebulizer, comprising: a body having a first end, a second end, an aerosol delivery channel extending through the body from the first end to the second end, and a fluid reservoir receiving compartment in communication with the aerosol delivery channel, the first end of the body having a mouthpiece a fluid reservoir positioned in the fluid reservoir receiving compartment, the fluid reservoir containing a volume of fluid and having a vibrating mesh disc for delivering the fluid to the aerosol delivery channel in an aerosol form upon the vibrating mesh disc being energized and a flutter valve positioned in the aerosol delivery channel of the body near the second end of the body, the flutter valve moveable between a closed position and an open position when an expiratory pressure greater than a predetermined expiratory pressure is exerted on the flutter valve.Ģ. ![]()
