An apparatus (1) for cleansing wounds (5) in which irrigant fluid from a reservoir (12) connected to a conformable wound dressing (2) and wound exudate from the dressing are moved by a device (which may be a single pump or two pumps) for moving fluid through a flow path which passes through the dressing and a means for providing simultaneous aspiration and irrigation of the wound, and means for supplying physiologically active agents to the wound. The former provides a desired balance of fluid at a controlled nominal flow rate that removes materials deleterious to wound healing, while distributing materials that are beneficial in promoting wound healing over the wound bed. The latter maintains physiologically active agents at a level that promotes wound healing.
L'invention concerne un appareil (1) conçu pour nettoyer des plaies (5), dans lequel le fluide irriguant provenant d'un réservoir (12) relié à un pansement épousant les formes (2) et l'exsudat de la plaie provenant du pansement sont déplacés par un dispositif (qui peut consister en une pompe unique ou deux pompes) conçu pour déplacer le fluide dans un passage d'écoulement qui traverse le pansement. Il comprend également un élément conçu pour assurer une aspiration et une irrigation simultanées de la plaie, et un élément conçu pour alimenter la plaie en agents actifs au plan physiologique. Cet élément fournit l'équilibre de fluide souhaité à un débit nominal contrôlé, qui élimine les matières délétères afin de permettre la cicatrisation de la plaie, tout en fournissant les substances facilitant la cicatrisation sur le lit de la plaie. Ce dernier maintient les agents actifs au plan physiologique à un niveau qui facilite la cicatrisation.
