Abstract

The nebulizing chamber (10) for aerosol therapy comprises a tube (14) fed at a first end with compressed air, the tube (14) being constricted internally at its second end prior to the relative exit orifice (16) to obtain a venturi effect. The orifice (16) of the tube (14) emerges from the free surface of a solution (22) of an aerosol therapy medicament, a nozzle (18) being concentrically mounted on the second end of the tube (14) such that between the tube (14) and nozzle (18) there remains an interspace (20) which communicates with the solution (22). A flow breaker device (26) is provided above the orifice (30) of the nozzle (18). The chamber (10) is provided with an exit (34) for the formed aerosol and an inlet (24) for entry of external air as a result of suction exerted by the patient on the exit (34). Means are provided to vary the distance between the orifice (16) of the compressed air tube (14) and the orifice (30) of the nozzle (18).
