ABSTRACT:
A sanitary chamber is described which operates at room temperature to nebulize or aerosolize a liquid utilized in inhalation therapy. The chamber is a disposable thin walled flexible reservoir for containing a supply of liquid and for dispensing breathable gas such as air in admixture with the liquid. The chamber includes a flexible diaphragm responsive to ultrasonic vibrations of an abutting electroacoustic transducer for admixing the liquid and gas. The chamber further includes integrally formed dispensing means which serves to direct the emanating gas-liquid admixture in an ascending vortex pattern to promote evaporation at ambient temperature. In a particular embodiment, the chamber comprises an inflatable bag constructed of low-cost plastic film material which lends itself readily to compact and sterile storage and disposal.
