Abstract
A cylindrical cartridge having a housing containing a replenishable water supply is employed as a water supply source for producing an aerosol with an oxygen stream for inhalation therapy through the agency of a nebulizer adapter which couples pressurized oxygen to the water cartridge. A venturi-type insert member is disposed vertically with the cartridge. The venturi draws water from the water supply and directs atomized droplets of water and oxygen into a mixing chamber located above the water level in the cartridge. The cartridge has a vertical tubular portion with a connection to a source of oxygen or air and terminates above the level of the water in the cartridge. The aerosol flows out of the cartridge through an outlet nozzle. The cartridge is an elongated housing having a capillary active cylindrical absorption surface means internally whereby water is drawn up along the cartridge's cylindrical body wall which serves as an evaporating surface.
