An apparatus for cleansing and applying therapy or prophylaxis to wounds, in which irrigant fluid containing a physiologically active material from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

L'invention concerne un dispositif de nettoyage et d'application de soins thérapeutiques ou prophylactiques à des plaies. Dans ce dispositif, un fluide irrigateur contenant une substance physiologiquement active provenant d'un réservoir relié à un pansement adaptable ainsi que l'exsudat libéré par le pansement sont recyclés par un organe qui conduit le fluide à travers un circuit d'écoulement qui passe par le pansement; des moyens permettent par ailleurs de purifier le fluide et de le renvoyer au pansement. Les moyens de nettoyage (lesquels peuvent être monophasiques, par ex. un système de micro-filtration, ou diphasiques, par ex. un système dialytique) éliminent les matières nuisibles à la cicatrisation de la plaie. Le fluide purifié, encore chargé de substances bénéfiques qui favorisent la cicatrisation des plaies, est renvoyé au lit de la plaie. L'invention concerne en outre un pansement et un procédé de traitement utilisant ce dispositif.
