A breath sampling device has a body defining an interior space or bore with two open ends. The patient's breath is directed through the device from end to end, thereby continually purging the interior space. At a designated time during the breath, closure devices are actuated to shut both ends, desirably in response to a single actuation actuation thereby capturing a breath sample at a predetermined time. The continual purging action assures that the captured breath sample truly represents the breath at the designated time during the exhalation cycle.

Dispositif de prélèvement d'haleine constitué d'un corps formant un espace intérieur ou un alésage présentant deux extrémités libres. Le patient dirige son haleine à travers le dispositif, d'une extrémité à l'autre, éliminant ainsi continuellement l'air se trouvant à l'intérieur. € un moment précis durant l'exhalation, des dispositifs de fermeture sont actionnés pour boucher les deux extrémités, de préférence en réponse à une simple commande, ce qui permet d'obtenir un échantillon d'haleine à un moment prédéterminé. Grâce à l'action continue d'élimination, l'échantillon prélevé correspond réellement à l'haleine du patient au moment désigné durant le cycle d'exhalation.
