ABSTRACT:
A cylindrical cartridge having a housing containing a replinishable water supply is employed as a water supply source for producing an aerosol with an oxygen stream for inhalation therapy to the agency of a nebulizer adapter which couples pressurized oxygen to the cartridge module. The cartridge module is separated in two compartments by means of a metallic disc positioned horizontally in the approximate center thereof and having a tube extending above and below the disc. Water is drawn from the water supply through the tube and into the mixing chamber located above the disc in the cartridge module. The cartridge has a vertical tubular portion with connections to a source of oxygen or air which terminates above the top of the tubing extending through the disc. The aerosol flows out of the cartridge through an outlet nozzle. The cartridge is an elongated housing having a temporary active cylindrical absorption surface means internally above the disc which serves as an evaporating surface.
