초록 ▼

Many embodiments of wound filling devices and methods of their use in systems for the application of negative pressure therapy are described herein. In one embodiment, a wound filling device comprises: an inflatable bag member having at least one fluid carrying conduit operably connected thereto to inflate/deflate said bag member; a separate textured covering sock member at least partially covering the inflatable bag member. Another embodiment comprises a three-dimensional wound packing member, and may optionally comprise a plurality of such members linked together. Certain embodiments of wound packing members may comprise a porous bag member adapted to be non-adherent to the wound. Yet other embodiments may comprise a non-porous bag member provided with means to connect a fluid supply to the interior.

대표청구항 ▼

1. A wound healing system for promoting healing of a wound of a patient, the system comprising: a positive pressure source;a reduced pressure source;a sealing drape configured to form a sealed cavity over the wound;a foam sock member comprising an upper portion adjoining a lower portion, wherein the upper portion and the lower portion define a substantially enclosed chamber between the upper portion and the lower portion,wherein the lower portion is configured to be positioned in contact with the wound,wherein the upper portion is configured to be positioned between the lower portion and the sealing drape, andwherein the foam sock member comprises a plurality of channels over a surface of the foam sock member and is configured to provide an interface with the wound to drain fluid away from the wound, the plurality of channels being in fluid communication with the reduced pressure source; anda substantially impervious inflatable bag member comprising a top portion adjoining a bottom portion, wherein the top portion and the bottom portion define a substantially enclosed interior volume in fluid communication with the positive pressure source via a port passing through the upper portion of the foam sock member and adjoining the top portion of the inflatable bag member,wherein the interior volume is configured to he expanded under positive pressure applied by the positive pressure source, andwherein the inflatable bag member is enclosed within the chamber of the foam sock member. 2. The wound healing system of claim 1, wherein the positive pressure source and the negative pressure source are separate pumps. 3. The wound healing system of claim 1, wherein the foam sock member comprises a polyurethane, open-cell, reticulated foam. 4. The wound healing system of claim 1, wherein the foam sock member comprises a granulation-promoting surface in contact with the wound to induce microstrain at the wound when the filler member is expanded. 5. A wound healing system for promoting healing of a wound of a patient, the system comprising: a positive pressure source;a reduced pressure source;a sealing drape configured to form a sealed cavity over the wound;a foam sock member having a surface with a plurality of channels configured to be positioned in contact with the wound to drain fluid away from the wound, the plurality of channels in fluid communication with the reduced pressure source, the foam sock member having an upper portion and a lower portion, wherein the upper portion is configured to be positioned between the lower portion and the sealing drape;an inflatable bag member having a substantially impervious flexible wall defining an interior chamber, the interior chamber being in fluid communication with the positive pressure source via a port passing through the foam sock member and adjoining the inflatable bag member, wherein the inflatable bag member is positioned within and surrounded by the foam sock member and is configured to be expanded under positive pressure applied by the positive pressure source.
