Abstract:
1. A wound ventilation system for treatment of a wound, the system comprising: a wound dressing having an inlet and an outlet, the wound dressing being configured to form a substantially airtight cover over the wound; including a free flow of air and a controlled flow of oxygen that passes through a mixture plenum to provide the gas at atmospheric pressure the gas being in communication with the inlet of the wound dressing; a vacuum source in communication with the outlet of the wound dressing, the vacuum source being configured to draw gas through the wound dressing; a gas flow controller disposed between the mixture plenum and the inlet of the wound dressing, the gas flow controller being configured to regulate the flow of gas drawn by the vacuum source and thereby establish less than atmospheric gas pressure between the gas flow controller and the vacuum source; a humidifier humidifying the gas entering the inlet of the wound dressing, the humidifier receiving and humidifying the gas at no more than atmospheric pressure; a heater located prior to an exit of said humidifier; and a re-heater located after said exit of said humidifier configured to heat the gas flowing to the wound and to minimize any condensate that may be formed.
