This invention is a breathing apparatus (10) having a main body (12) with a generally cylindrical inner cavity. The main body (12) has a main aperture (20) for the user to breath into, and at least two sets of outer opening (32, 34). An inner cylinder (14) is coaxially disposed within the inner cavity (22) of the main body (12) and is adapted to move relative to the main body (12). The inner cylinder (14) has an open end (28) adjacent the main aperture (20), and at least two sets of inner openings (42, 44) selectively mating with openings (32, 34) in the main body (12) upon movement of the inner cylinder (14) with respect to the main body (12). By selecting the appropriate alignment of openings (32, 34, 42, 44), either resistive, percussing, or pulsing breathing exercises can be performed.

Cette invention concerne un appareil respiratoire (10) comportant un corps principal (12) ayant une cavité interne globalement cylindrique. Ce corps principal (12) possède une ouverture principale (20) dans laquelle un utilisateur expire, et au moins deux ensembles d'orifices externes (32, 34). Un cylindre interne (14) est disposé coaxialement dans la cavité interne (22) du corps principal (12), et peut se déplacer par rapport à ce dernier (12). Le cylindre interne (14) possède une extrémité ouverte (28) située à proximité de l'ouverture principale (20), et au moins deux ensembles d'orifices internes (42, 44) pouvant correspondre de manière sélective aux orifices (32, 34) du corps principal (12) lors du déplacement du cylindre interne dans ledit corps principal (12). En choisissant un alignement adéquat des orifices (32, 34, 42, 44), il est possible d'effectuer des exercices respiratoires soit par effet de résistance, soit par percussions, soit par impulsions.
