    Abstract: The illustrative embodiments described herein are directed to a manually-actuated pump and method for applying reduced pressure at a tissue site. The manually-actuated pump includes at least one variable volume chamber that is manually compressible into a plurality of positions. The manually-actuated pump includes a fixed volume chamber in communication with the at least one variable volume chamber. The manually-actuated pump also includes a filter housing having a hydrophobic filter that prevents liquid from entering the at least one variable volume chamber. The fixed volume chamber is coupled to the at least one variable volume chamber via the filter housing. The filter housing is located in between the at least one variable volume chamber and the fixed volume chamber. The fixed volume chamber has reduced pressure that is applied to the tissue site in response to a movement of the at least one variable volume chamber from a compressed position in the plurality of positions to an uncompressed position in the plurality of positions.

    Abstract: A reduced pressure treatment system includes a compressible chamber positionable beneath a foot of a user and being movable between an expanded position and a compressed position. The compressible chamber includes an inlet and an outlet. An inlet valve is in fluid communication with the inlet to prevent fluid within the compressible chamber from exiting the inlet, and an outlet valve is in fluid communication with the outlet to prevent fluid from entering the compressible chamber through the outlet. A biasing member is disposed within the compressible chamber to bias the compressible chamber toward the expanded position, and a manifold is positionable at a tissue site and in fluid communication with the inlet of the compressible chamber.

    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.

    Abstract: An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a healing manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing comprises a layer of porous foam material enclosed by sheets of elastomeric material punctuated by a number of appropriately placed holes. Multiple layers of porous foam may also be used. A suction tube connector is provided on an upper surface of a layer of foam for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope and through the foam.
