    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 therapeutic apparatus for stimulating the healing of a wound site includes a polyurethane foam positioned at the wound site and a connector having a disc-like cup and an elbow-shaped spout. The connector is positioned in contact with the polyurethane foam, and the elbow-shaped spout is configured for connection to a tube that is capable of delivering negative pressure through the elbow-shaped spout and to the polyurethane foam. The therapeutic apparatus further includes a drape having a hole, the drape being positioned over the connector such that the elbow-shaped spout extends through the hole in the drape.

    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: A manually-activated reduced pressure treatment system includes a substantially rigid housing, and an end cap slidingly received by the housing. An inner chamber is disposed between the end cap and housing, and a volume of the inner chamber is variable in amount depending on the position of the end cap within the housing. The end cap is slidingly movable between an uncompressed position at which the volume of the inner chamber is at a maximum value and a compressed position at which the volume of the inner chamber is at a minimum value. A position indicating member is associated with the end cap and housing to indicate the position of the end cap relative to the housing at predetermined positions between the uncompressed position and the compressed position.
