CA 2718425

The present disclosure describes a dressing for use in a vacuum wound therapy procedure to promote healing of a wound. The dressing includes a cover layer for positioning over a wound to define a reservoir in which a reduced pressure may be maintained over the wound. A portal member is mounted relative to the cover layer and defines a fluid passage for fluid coupling with a reduced pressure supply conduit for creating the reduced pressure within the reservoir. A filter screen is mounted relative to the fluid passage and is dimensioned to minimize passage of tissue particles of predetermined dimension through the fluid passage of the portal member.

La présente invention concerne un pansement utilisable dans le traitement des plaies par pression négative afin de stimuler la cicatrisation dune plaie. Le pansement comprend une couche de fermeture que lon dispose sur une plaie de façon à définir un réservoir dans lequel une pression réduite peut être maintenue sur la plaie. Un élément formant porte est monté par rapport à la couche de fermeture et il définit un passage de fluide pour un couplage fluidique avec un conduit de pression réduite afin de créer la pression réduite à lintérieur du réservoir. Un tamis filtrant est monté par rapport au passage de fluide et il est dimensionné de façon à minimiser le passage de particules tissulaires dune dimension prédéterminée à travers le passage de fluide de lélément formant porte.
