    摘要： A system for administering negative pressure therapy to a wound includes a screen adapted to be positioned at the wound. A reduced pressure source is in fluid communication with the screen, and a blood gas transducer is exposed to a reduced pressure provided by the reduced pressure source. The reduced pressure supplied by the reduced pressure source induces hyperperfusion of a blood gas at the wound.

    摘要： A biocompatible wound dressing comprised of a pad for insertion substantially into a wound site and wound drape for sealing enclosure of the foam pad at the wound site. The pad, comprised of a foam or other like material having relatively few open cells in contact with the areas upon which cell growth is to be encouraged so as to avoid unwanted adhesions, but having sufficiently numerous open cells so that drainage and negative pressure therapy may continue unimpaired, is placed in fluid communication with a vacuum source for promotion of fluid drainage, as known in the art. The pad is further comprised of an ultra-low density fused-fibrous ceramic, or a bioabsorbable branched polymer, or cell growth enhancing matrix or scaffolding.

    摘要： A wound closure apparatus having a housing that contains a vacuum pump and a chamber for holding a disposable wound fluid collection canister. The canister resides within the chamber and connects at an outlet with the vacuum pump at an inlet with a porous wound pad. The pad is placed over or within a wound and adhesively secured thereto. When the vacuum pump activates, it evacuates air from the canister resulting in wound fluids flowing from the wound into the canister. Due to the negative effect that a vacuum can impose on tissue when granulation tissue is pulled into the pad, the pad contains multiple pore sizes to prevent granulation tissue from migrating into the pad. The pad has an outer surface adjacent the wound with pore sizes of a diameter of approximately 100 microns or less to prevent tissue from growing into the pad and is treated for biocompatibility.
