An apparatus for cleansing wounds in which irrigant fluid from a reservoir (12) connected to a conformable wound dressing (3) and wound exudate from the dres sing are recirculated by a device (18) for moving fluid through a flow path which passes through the dressing and a means (17) for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. micro~filtration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing mate rials that are beneficial in promoting wound healing, is returned to the wound bed.

L'invention concerne un appareil permettant de nettoyer des plaies. Dans cet appareil, un fluide d'irrigation provenant d'un réservoir (12) relié à un pansement adaptable (3) et l'exsudat du pansement sont recyclés par un dispositif (18). Ce dispositif permet de déplacer ces fluides à travers une voie d'acheminement qui traverse le pansement et des moyens (17) de nettoyage de fluide et de les reacheminer ensuite vers le pansement. Lesdits moyens de nettoyage peuvent être un système à phase unique, tel qu'un système de micro-filtration, ou un système biphasé, tel qu'un système dialytique. Les moyens de nettoyage extraient des matières délétères à la cicatrisation de la plaie, et le fluide nettoyé, contenant encore des matières qui favorisent la cicatrisation de la plaie, est reacheminé vers le fond de la plaie. L'invention concerne ledit pansement et la méthode de traitement à l'aide dudit appareil.
