Abstract

The improved medical nebulization device includes a head and a removeable depending liquid reservoir. The head has a closed top, closed sides and open bottom defining a central space in which is secured a nebulization chamber having closed sides and an open top and open bottom. A nebulization baffle is connected to the head top and extends into the nebulization chamber. A liquid draw tube is connected to the baffle and depends from the chamber into the reservoir. A nebulized aerosol output port extends between the space outside the chamber and a point peripheral of the head for supplying nebulized aerosol to a patient. An auxiliary multiple gas entrainment inlet port, with removeable cap, extends into the chamber at a point remote from the output port and is adapted to supply auxiliary gases such as a mixture of oxygen and helium. The liquid reservoir in one embodiment includes a graduated liquid measuring scale and is transparent. The baffle in one embodiment is an annular flow aerosol nozzle secured to the underside of the top of the head. The device permits accurate adjustment of the types of nebulized liquid-gas mixture supplied to a patient.
