A liquid separator for a respiratory gas sample analyzer includes a closed container having a liquid trap filter chamber integral with the container. The liquid trap filter chamber includes an inlet compartment and an outlet compartment. The inlet compartment is interposed between a sample inlet port and a sample outlet port and includes a gas permeable, liquid impermeable filter element for separating liquid from a gas sample, the liquid separated from the gas sample passing to a collection chamber. The outlet compartment includes a further gas permeable, liquid impermeable trap filter element which is interposed between the collection chamber and a low pressure port, for preventing the flow of liquid' through the output compartment to the low pressure port.
L'invention concerne un séparateur de liquide pour analyseur d'échantillon de gaz respiratoire, comprenant un récipient fermé (12) dans lequel est intégré une chambre (16) équipée d'un filtre à liquide. La chambre équipée du filtre à liquide comprend un compartiment (26) d'entrée et un compartiment (30) de sortie. Le compartiment d'entrée est interposé entre un orifice (14) d'entrée d'échantillon et un orifice (18) de sortie d'échantillon, et comprend un élément filtrant (24) perméable aux gaz et imperméable aux liquides permettant de séparer le liquide d'un échantillon gazeux, le liquide séparé de l'échantillon gazeux passant dans un collecteur (20). Le compartiment de sortie comprend un autre élément filtrant (28) perméable aux gaz et imperméable aux liquides, interposé entre le collecteur et un orifice (22) basse pression, afin d'empêcher l'écoulement de liquide à travers le compartiment de sortie dans l'orifice basse pression.
