The invention refers to a device for collecting liquid from exhalation gas from a patient. The device includes a first pipe conduit (5, 8) for the supply of inhalation gas to the patient, a second pipe conduit (6, 9) for the removal of exhalation gas from the patient and a container device (1) for collecting liquid from the exhalation gas. The container device includes a first space (2), which forms a portion of the first pipe conduit (5, 8) and through which the inhalation gas thus flows, and a second space (3), which forms a portion of the second pipe conduit (6, 9) and through which the exhalation gas thus flows. The second space (3) is arranged to receive the collected liquid. The first space (2) is separated from the second space (3) by means of a wall member (4), which has a good thermal conductivity and permits transfer of heat from the exhalation gas to the inhalation gas.

La présente invention concerne un dispositif permettant de recueillir un liquide à partir d'un gaz d'exhalation d'un patient. Ce dispositif comprend un premier tuyau conduit (5, 6) destiné à délivrer un gaz d'inhalation au patient, un second tuyau conduit (6, 9) destiné à récupérer le gaz d'exhalation du patient et un dispositif récipient (1) destiné à recueillir un liquide à partir de ce gaz d'exhalation. Ce dispositif récipient comprend un premier espace (2), qui forme une partie du premier tuyau conduit (5, 8) et à travers laquelle, par conséquent, le gaz d'inhalation s'écoule, et un second espace (3), qui forme une partie du second tuyau conduit (6, 9) et à travers laquelle, par conséquent, le gaz d'exhalation s'écoule. Ce second espace (2) est agencé de façon à recevoir le liquide recueilli. Le premier espace (2) est séparé du second espace (3) au moyen d'une cloison (4), qui possède une bonne conductivité thermique et permet de transférer la chaleur du gaz d'exhalation au gaz d'inhalation.
