Abstract
A nebulizer for forming a liquid mist in a stream of gas. The nebulizing chamber carries a liquid suction conduit adapted to communicate with a supply of liquid below the nebulizing chamber. Accordingly, as suction is exerted on the nebulizing chamber, for example, by a patient breathing in, liquid is drawn upwardly into the nebulizing chamber through the suction conduit. When the liquid reaches a predetermined level it enters into the nebulizing apparatus of the device, with the result that nebulization only takes place at a predetermined minimum level of suction.
