CA 2658598

A medical dressing (10) has a flexible panel (12) with adhesive on one side (16) for attaching to the skin of the patient about a wound. A one-way valve assembly (14) is mounted over an opening in the panel and includes a valve body (26) defining two separate fluid passages (66, 68). A valve member (64) is configured to permit air and or/other fluids to flow through a first of the passages (66) in an outward direction only so that air and/or other fluids are able to exit the wound through the first passage but are prevented from entering the wound through the first passage. A removable closure member (70) is provided for selectively closing the second passage (68) to prevent fluid flow through the second passage. The closure member (70) can be removed to enable direct access to the wound through the second passage (68). The dressing is particularly suitable for use in occluding an open chest wound.

L'invention concerne un pansement médical (10) doté d'un panneau flexible (12) muni d'un adhésif sur un côté (16) et permettant ainsi une fixation sur la peau saine entourant une plaie. Un ensemble de valve unidirectionnelle (14) est monté sur une ouverture du panneau et comprend un corps de valve (26) définissant deux passages de fluide séparés (66, 68). Un élément de valve (64) est configuré pour permettre à de l'air et/ou à d'autres fluides de s'écouler à travers l'un des deux passages (66) vers l'extérieur seulement de telle sorte que l'air et/ou les autres fluides peuvent sortir de la plaie par le premier passage mais ne peuvent pas entrer dans la plaie par le premier passage. Un élément de fermeture amovible (70) est prévu pour fermer de façon sélective le second passage (68) et empêcher un écoulement de fluide par le second passage. L'élément de fermeture (70) peut être retiré pour permettre un accès direct à la plaie par le second passage (68). Le pansement est particulièrement approprié pour occlure une plaie ouverte à la poitrine.
