Description

FIELD OF THE INVENTION

[0001] This invention provides wound healing systems, which comprise dressings; which may be composed of at least two layers, which include a first absorptive and / or conductive and a second fluid impermeable layer and which system delivers oxygen to the wound bed and applies negative pressure thereto, where the source of oxygen and negative pressure are simultaneously applied to distal sites of the dressing. The system may comprise a fluid trap for collection of conveyed fluid and / or debris, which may further comprise a sensor for detection of changes in fluid volume or characteristics, a sensor to detect local pressure at the wound and distal limb, a controller to regulate differential vacuum levels and a means to regulate and synchronize application of negative pressure and oxygen. The invention is further directed to the application of oxygen and negative pressure wounds for use in treating such wounds, or treating or preventing anaerobic infection of such wo...
