Abstract

DISPOSITIVO DE AMOSTRAGEM É descrito um dispositivo para medir um componente na exalação compreendendo uma entrada (32) para receber a exalação, uma câmara de armazenamento temporário (31). Um primeiro duto de fluido (34a) fica em conexão fluida com a entrada e é adaptado para levar uma primeira porção (I') da exalação para a câmara de armazenamento temporário. A câmara de armazenamento temporário compreende uma saída (37) para descartar uma primeira parte da exalação recebida do primeiro duto de fluido e a câmara de armazenamento temporário é configurada para armazenar uma segunda parte da exalação recebida do primeiro duto de fluido. o dispositivo compreende um segundo duto de fluido (34b) em conexão fluida com a entrada e adaptado para levar uma segunda porção (I") da exalação para ser descartada, e um sensor (63) para medir um componente na exalação armazenada na câmara de armazenamento temporário.
