Title
(EN) MOISTURE PERMEABLE CONDUIT FOR A BREATHING CIRCUIT
(FR) CONDUIT PERMÉABLE À L'HUMIDITÉ POUR CIRCUIT RESPIRATOIRE
Abstract
(EN)
There is provided a flexible, helically wound conduit for a breathing circuit comprising an inlet (1), an outlet (3), and an enclosing wall (2) defining a flow passage between said inlet and said outlet, wherein at least a region of said enclosing wall is permeable to water vapor and one or more of 02 and CO2, and wherein the axial tensile strength of the enclosing wall is greater than 40N. Further provided are limbs comprising the conduit, a method of manufacturing the conduit and the use of the conduit to remove water vapor and/or CO2 from gas exhaled by a patient.
(FR)
L'invention concerne un conduit flexible à enroulement hélicoïdal pour un circuit respiratoire comprenant une entrée (1), une sortie (3), et une paroi d'enceinte (2) définissant un passage d'écoulement entre ladite entrée et ladite sortie, au moins une région de ladite paroi d'enceinte étant perméable à la vapeur d'eau et à un ou plusieurs des éléments 02 et CO2, la résistance à la traction axiale de la paroi d'enceinte étant supérieure à 40N. L'invention concerne en outre des membres comprenant le conduit, un procédé de fabrication du conduit et l'utilisation du conduit pour éliminer la vapeur d'eau et/ou le CO2 des gaz expirés par un patient.
