Abstract
A wound dressing for an aspirated wound dressing system, with a wound interface region for contacting or facing a wound site; an aspiration port for receiving suction for aspiration of wound exudate; a liquid permeable pressure barrier disposed between the wound interface region and the aspiration port for substantially preventing application of negative pressure from the aspiration port to the wound interface region; at least one atmospheric vent for equalizing with atmosphere the pressure at the wound interface region; and a liquid sensor for sensing liquid within the wound dressing for controlling application of suction by the aspiration unit.
