Abstract: A sonic nebulizer having an electronic powered piezo-electric crystal to produce mechanical vibrations which are transmitted through a coupling fluid and focused on a second fluid contained in a chamber having a tangentially directed pressurized air inlet and a central opening whereby the nebulized second fluid is entrained by the vortex air flow generated in the chamber and the resulting fluid mixture carried through the outlet. The coupling fluid, electric power oscillator, piezo-electric crystal and associated control apparatus are contained by a portable casing which presents a compact, lightweight and rugged unit particularly adapted for short or long term use in supplying medicated air or oxygen to a patient undergoing medical care. The chamber containing the nebulized second fluid is made of an inexpensive, transparent material which is quickly and easily mounted to the casing and attached to inlet and outlet hoses. The inlet and outlet hoses, like the chamber, may be made from inexpensive material and together with the chamber constitute a disposable portion to avoid contamination between patients.

Abstract: A vortex valve for use in a fluid oscillator circuit characterized by exhibiting a pronounced negative resistance characteristic in a portion of its operating range and by having a vortex chamber defined in part by a resiliently movable portion to provide a mechanical output in response to pressure variations in the chamber. This particular vortex valve is incorporated into a fluid oscillator arrangement to produce oscillatory pulses in the vortex chamber and responsive movements of the movable portion by adjusting the control and supply pressures and flows so as to be in the negative resistance range of the vortex valve while at the same time maintaining a constant supply flow.
