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 amo...
A nebulizer for inhalation therapy comprising a mixer housing having a mixing chamber therein with an open end, said housing having first and second input ports, a venturi tube mounted in said open end, said venturi tube including an input end having an entrance surface tapering inwardly toward the axis of said tube and toward said open end, nozzle means in said chamber connected to said first port for projecting a first stream of high velocity oxygen from said first port along a first axis in said chamber, an aspirating conduit having an end in said cha...
