ABSTRACT:
The nebulizing device (44') and apparatus (10) for supplying nebulized liquids or powders for inhalation is provided. The device (44') include a base (108) having a closed bore (50) and an annular passageway (60) extending from the bore to an outlet (62). At least one auxiliary passage (62) is provided which extends through the base from the bore and opens to the passageway. Compressed gas is supplied through a supply hose (52) to the bore. A liquid port (118) extends from a liquid supply to the passageway adjacent the outlet such than when compressed gas is supplied to the bore the gas flows through the passageway and is discharged from the outlet, generating a subatmospheric pressure region to draw the liquid through the port into the passageway, the gas further generating a vortex action to nebulize the liquid. A plurality of screens (88, 92, 100) may be provided in series to further slow and nebulize the liquid. The apparatus includes a container (12). A top (22) is affixed to the container and includes a cavity (40). Nebulized liquid passes, in series, through the screens which act in cooperation with the device (44, 44') to provide a nebulized liquid.
