ABSTRACT:
A nebulizer cap for oxygen therapy and the like includes a cap body, having attachment means for sealingly connecting the cap body to a container for liquid to be neubulized. A dip tube is carried by the cap body to extend into the container, with the one end of the tube being in flow communication with conduit means defined by the cap body. The conduit means communicates with the liquid inlet of a nebulizing venturi, while a gas port passes through the cap body to the exterior, and is in communication with a gas inlet of the nebulizing venturi. The conduit leading from the dip tube to the liquid inlet of the venturi is defined by open channels, positioned on an upstanding portion of the cap body. A thin metal heat exchange shell is sealingly positioned over the upstanding portion of the cap body to enclose the channels, which preferably define a zig-zag flow pattern. A toroidal heater can fit over the shell when heating is desired.
