Abstract: A method, and apparatus for the controlled acceleration, and/or retardation of the body's inflammatory response generally comprises a foam pad for insertion substantially into a wound site, a heating, a cooling pad for application over the wound site, a wound drape or sealing enclosure of the foam pad, the heating, and cooling pad at wound site. The foam pad is placed in fluid communication with a vacuum source for promotion of the controlled acceleration or retardation of the body's inflammatory response. The heating, and cooling provision controls the local metabolic function as part of the inflammatory response.

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.

Abstract translation: 描述了腹部伤口敷料和使用方法，其能够以愈合方式对伤口部位施加负压，同时也限制了防止敷料除去的粘连的形成。 敷料包括由多个适当放置的孔标出的弹性材料片所包围的多孔泡沫材料层。 也可以使用多层多孔泡沫。 抽吸管连接器设置在泡沫层的上表面上，用于连接到负压源。 至少一层泡沫被包裹在弹性体材料中，并且与开放伤口内的组织直接接触。 流体通过负压通过位于弹性体外壳中的孔并通过泡沫来拉伸。
