Sidestream gas sampling assembly (10, 54, 70) that does not substantially degrade the waveform of expired gases. The gas sampling assembly includes a sample cell portion (14, 14', 14", 14"') integrated with a filter portion (12, 12', 12") for separating undesired liquid condensate from respiratory gases to be monitored. The gas sampling assembly is configured to receive expired gases through a gas sampling line, filter undesired liquid condensate from the expired gases through hydrophobic fiber elements and communicate the filtered gases to a sample chamber which is in close proximity to the filter where measurements may be taken thereof e.g., optical or infrared sensing mechanisms. The gases that are substantially free of liquid condensate are then exhausted from the sample chamber.

L'invention concerne un ensemble de prélèvement latéral de gaz (10, 54, 70) qui n'abîme pratiquement pas la forme d'onde des gaz expirés. Cet ensemble de prélèvement de gaz comprend une partie de cellule échantillon (14, 14', 14", 14" ) intégrée et une partie de filtre (12, 12', 12") permettant de séparer le condensat liquide indésirable des gaz respiratoires à contrôler. L'ensemble de prélèvement de gaz est conçu de manière à recevoir des gaz expirés à travers une ligne de prélèvement de gaz, à filtrer le condensat liquide indésirable des gaz expirés au moyen d'éléments en fibres hydrophobes et à communiquer les gaz filtrés à une chambre de prélèvement qui se trouve à proximité du filtre, là où des mesures peuvent être prises, par exemple des mécanismes de détection optiques ou aux infrarouges. Les gaz qui ne contiennent pratiquement pas de condensat liquide sont ensuite évacués de la chambre de prélèvement.
