Abstract
A nebulizer has a mixing chamber into which is projected a high velocity jet of oxygen that aspirates water from a container connected with the mixing chamber. A compressed air input port in the chamber projects a stream of compressed air adjacent to and alongside the oxygen jet to impinge upon the tapered entrance surface of a venturi tube that forms an exit from the mixing chamber. The percentage of oxygen in the output is effectively rendered independent of output back pressure, the lower limit of the amount of oxygen in the output is lowered, the amount of water entrained in the output is increased, and the amount of waste water is decreased.
