Abstract: Disclosed herein are several embodiments of a negative pressure system and methods of using the same in the treatment of wounds. Some embodiments are directed to a system that utilizes a wound dressing with at least three layers. These embodiments are directed toward improved distribution of negative pressure to a wound and periwound site surrounding the wound.

Abstract: Disclosed herein are several embodiments of a negative pressure system and methods of using the same in the treatment of wounds. Some embodiments are directed to a system that utilizes a wound dressing with at least three layers. These embodiments are directed toward improved distribution of negative pressure to a wound and periwound site surrounding the wound. Some embodiments are directed to a fixation strip for sealing a wound dressing to a wound and periwound site. The fixation strip can comprise multiple layers including an adhering layer, a wound sealing layer and at least one protective liner.

Abstract: Disclosed embodiments related to a wound dressing for treating circumferential wounds for use in a negative pressure wound therapy (NPWT). The wound dressing can include a cover layer, a plurality of spacer sections, and a wound contact layer. The wound dressing can further include a port for connection to a source of negative pressure and a connector for fluidically connecting each of the plurality of sections with the port.

Abstract: Disclosed embodiments relate to wound therapy apparatuses and methods for use in negative pressure wound therapy (NPWT). Such wound therapy apparatuses and methods may reduce maceration during NPWT. The wound therapy apparatus may include a porous hydrophobic layer surrounded by a hydrophilic ring. The hydrophilic ring may serve to prevent passage of liquid while negative pressure is applied to the wound, but allow liquid passage to an absorbent ring when negative pressure is no longer applied. A transmission layer may also be included, underlying the absorbent layer.
