CA 2606245

An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing 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. The apparatus also comprises means to apply high frequency vibrational energy, e.g. ultrasound, to the wound bed. The former removes materials deleterious to wound healing, while distributing materials that are beneficial in promoting wound healing over the wound bed. The latter promotes healing. The dressing and a method of treatment using the apparatus.

L'invention concerne un appareil de nettoyage de plaies dans lequel un liquide d'irrigation en provenance d'un réservoir en communication avec un pansement à forme adaptable et un exsudat en provenance du pansement sont déplacés par un dispositif (qui peut comprendre une pompe unique ou deux pompes) destiné à déplacer un liquide par l'intermédiaire d'un chemin d'écoulement traversant le pansement, une unité assurant une aspiration et une irrigation simultanées de la plaie. Cet appareil comprend également une unité destinée à appliquer une énergie vibratoire haute fréquence, et notamment des ultrasons, sur le lit de la plaie. La première unité permet d'enlever les matières empêchant la cicatrisation de la plaie tout en distribuant des substances favorisant la cicatrisation sur le lit de la plaie. La dernière unité contribue à faciliter la cicatrisation de la plaie. L'invention concerne également ce pansement et une méthode de traitement faisant appel audit appareil.
