The present invention relates to a tracheostomy device with an inflatable balloon (1) attached to a hollow tube (2) by means of two areas of adhesion (la and lb) whose orthogonal projections are not contiguous or, in other words, are at an angle () other than 180 °. This balloon (1) communicates with the environment by means of a capped, valved flexible conduit (4) A movable flange (3) allows for extra fixation of the device around a patient's neck A displaceable inner tube (5) can be removed in case of severe acute obstruction, allowing for immediate establishment of air flow. The design and distribution of the components of this tracheostomy device contribute to increased safety and comfort of tracheostomies by: enhancing its anchorability, hence better stabilizing it within the trachea; improving its placement within the airway; increasing the volume, hence lowering the pressure inside its balloon (1); enhancing the balloon's (1) volume-to-pressure curve, completely sealing the trachea from the tracheostomy wound, larynx and pharynx, shortening the tube (2) size and providing a movable neck flange (3).

La présente invention concerne un dispositif pour trachéotomie comportant un ballonnet gonflable (1) fixé à un tube (2) en deux zones (1a et 1b) dont les projections orthogonales ne sont pas contiguës, c'est-à-dire qu'elles font un ( ) différent de 180 DEG . Ce ballonnet (1) communique avec l'extérieur par un conduit souple coiffé (4) à soupape (4). Une collerette mobile (3) renforce la fixation du dispositif autour du cou du patient. Un tube intérieur déplaçable (5) peut être retiré en cas d'obstruction aiguë grave pour rétablissement immédiat de la circulation d'air. L'agencement et la répartition des éléments constitutifs de ce dispositif de trachéotomie contribue à accroître la sécurité et le confort pour les raisons suivantes : meilleure fixation du dispositif, et donc stabilité plus grande dans la trachée, meilleure mise en place dans les voies respiratoires; augmentation du volume et donc moindre pression dans le ballonnet (1); courbe volume-pression plus favorables du ballonnet (1); trachée complètement isolée de l'incision de la trachéotomie, du larynx et du pharynx; tube (2) plus court et emploi d'une collerette (mobile()) (3).
