Patent

CA 2390513

Apparatus is disclosed for applying negative pressure to a wound site to promote healing. The apparatus includes a porous pad for application to the wound, a suction tube linking the porous pad to a source of negative pressure, a container for collecting fluid exudate from the wound interposed between the porous pad and the source of negative pressure and a quick disconnect connector linking a first section of the suction tube leading to the porous pad with a second section leading to the container, said connector comprising two separable and non-interchangeable parts, said first section of the suction tube comprising a multi-lumen tube, one lumen being provided for applying suction to the porous pad and another being provided for monitoring pressure, said multi-lumen tube being fixedly attached at one end to the container and at the other end to one of said separable parts, said one separable part including sealing means whereby the lumens are connected in air-tight manner to said second section of the suction tube.

L'invention concerne un appareil pour l'application d'une pression négative sur une plaie, de sorte que la cicatrisation de cette dernière soit favorisée. Ledit appareil comprend un tampon poreux à appliquer sur la plaie, un tube d'aspiration reliant le tampon poreux à une source de pression négative, un récipient pour collecter l'exsudat fluidique provenant de la plaie, prévu entre le tampon poreux et la source de pression négative et un raccord à débranchement rapide, reliant une première partie du tube d'aspiration s'étendant jusqu'au tampon poreux à une deuxième partie s'étendant jusqu'au récipient. Ledit raccord comporte deux pièces séparables et non-interchangeables, la première partie du tube d'aspiration comprenant un tube à plusieurs lumières dont une permet l'application de l'aspiration sur le tampon poreux, et l'autre permet de contrôler la pression. Ledit tube à lumières multiples est monté fixe au récipient par une extrémité, et, par l'autre extrémité, à une des pièces séparables, laquelle comprend un moyen d'étanchéité, et les lumières sont reliées de manière hermétique à ladite deuxième partie du tube d'aspiration.
