A pulmonary exercise device (10) comprises a tubular body (12) with an air inlet (32), an air outlet (34) and a mouthpiece (16). The air inlet (32) is closed by a one-way valve arrangement (36) which is resiliently biased closed by means of spring (52). The air outlet (34) is closed by a one-way valve arrangement (70) which is resiliently biased closed by means of spring (90). In another aspect the inlet (32) and outlet (34) are closed off by respective one way valves which prevent airflow in one direction and allow only a restricted flow in the other.
La présente invention concerne un dispositif d'exercices pulmonaires (10) comprenant un corps tubulaire (12) doté d'une entrée d'air (32), d'une sortie d'air (34) et d'un embout buccal (16). L'entrée d'air (32) est refermée par un dispositif de clapet anti-retour (36) qui est fermé par sollicitation résiliante au moyen d'un ressort (52). La sortie d'air (34) est fermée par un dispositif de clapet anti-retour (70) qui est fermé par sollicitation résiliante au moyen d'un ressort (90). Dans un autre aspect de l'invention, l'entrée (32) et la sortie (34) sont refermées respectivement par des clapets anti-retour qui empêchent le passage du flux d'air dans une direction et n'autorise le passage que d'un flux réduit dans l'autre direction.
