This invention is an air conduit assembly (10) positionable within a patient having an inhalation gas pathway (14) and a separate exhalation (32) gas pathway, so that with each exhalation secretions are forced progressively out of the patient through the exhalation gas pathway. In one embodiment, the assembly includes a flexible partition (504) attached along its longitudinal extension, which defines the inhalation gas pathway and separate exhalation gas pathway. A collapsible distal valve (40) member may also be attached to one side of the air conduit to urge the flexible partition against the opposite interior wall of the air conduit during exhalation. An insertable embodiment (700) also includes a support frame (706, 708) that may be positioned within an air conduit and a flexible partition coupled to the support frame.
L'invention porte sur un tube de ventilation endotrachéal (10) se plaçant sur un patient et présentant un conduit d'inhalation (14) et un conduit d'expiration (32) séparé, de manière à ce que les sécrétions s'échappent progressivement par le conduit d'expiration (32) à chaque expiration. Dans une variante, l'ensemble comporte une cloison souple (504) longitudinale qui sépare le conduit d'inhalation du conduit d'expiration. Une valve distale effaçable (40) peut être placée à l'une des extrémités du conduit pour pousser la cloison souple contre la paroi intérieure opposée du conduit d'air pendant l'expiration. Il en existe également une réalisation insérable (700) comportant un cadre support (706, 708) pouvant se placer dans un tube de ventilation et une cloison souple reliée au cadre support.
