Abstract
A system for stimulating the healing of tissue comprises a porous pad positioned within a wound cavity, and an airtight dressing secured over the pad, so as to provide an airtight seal to the wound cavity. A proximal end of a conduit is connectable to the dressing. A distal end of the conduit is connectable to a negative pressure source, which may be an electric pump housed within a portable housing, or wall suction. A canister is positioned along the conduit to retain exudates suctioned from the wound site during the application of negative pressure. A controller for automated oscillation of pressure over time is provided to further enhance and stimulate the healing of an open wound. A power management motor control for varying pump drive frequency and managing a portable power supply is provided to increase battery life and improve patient mobility.
