Abstract MOUTHPIECE FOR INHALATION THERAPY DEVICES The invention concerns a mouthpiece for inhalation therapy devices. An opening (14) is located on the basic body (1) of the mouthpiece for exhalation into the mouthpiece so that the exhaled air can escape through it. The opening (14) is covered by a flat, elastic valve element (12) of a nonreturn valve (11) in such a manner that, for the most part, a simulation of the missing wall of the basic body (1) in the area of the opening (14) is achieved. This insures that the flow conditions in the interior of the mouthpiece remain nearly unaffected by the opening (14) when, during inhalation, the flat, elastic valve element (12) lies flat on a level wall section of the basic body (1) and closes the opening (14). 11
