Systems and methods for protecting incisions

Abstract

The present invention provides systems and methods for protecting wounds, such as surgical incisions. In one embodiment, a dressing for protecting a wound includes: a support cushion configured to surround the wound, the support cushion having sidewalls defining a major axis and a minor axis, the support cushion including at least two perforations that traverse the sidewalls at offset locations; a reservoir configured to be suspended over and in engagement with the support cushion; and a cover configured to be positioned over the reservoir. The at least two perforations may define first and second interlocking J-shaped portions. The support cushion may include a wicking portion configured to surround the wound and a hydrophobic portion configured to surround the hydrophobic portion. The wicking portion may be configured to transfer fluid from the wound to the reservoir. Methods of applying the dressing, and kits including the dressing, also are provided.

1 . A dressing for protecting a wound, the dressing comprising:
 a support cushion configured to surround the wound, the support cushion having sidewalls defining a major axis and a minor axis, the support cushion including at least two perforations that traverse the sidewalls at offset locations;   a reservoir configured to be suspended over and in engagement with the support cushion; and   a cover configured to be positioned over the reservoir.   
     
     
         2 . The dressing of  claim 1  wherein the at least two perforations define first and second interlocking J-shaped portions. 
     
     
         3 . The dressing of  claim 1  wherein the support cushion comprises a hydrophobic portion and a wicking portion, the wicking portion being configured to surround the wound and the hydrophobic portion being configured to surround the wicking portion. 
     
     
         4 . The dressing of  claim 3  wherein the wicking portion is configured to transfer fluid from the wound to the reservoir. 
     
     
         5 . The dressing of  claim 3 , wherein the cover is configured to retain the reservoir in engagement with the wicking portion. 
     
     
         6 . The dressing of  claim 3 , wherein the wicking portion defines a flange of the support cushion, the flange having a ledge to accept a portion of the reservoir. 
     
     
         7 . The dressing of  claim 1 , wherein the support cushion includes additional perforations that enable removal of selected portions of the support cushion along the major axis to reduce a length of the support cushion along the major axis. 
     
     
         8 . The dressing of  claim 1 , wherein the support cushion includes additional perforations that enable removal of selected portions of the support cushion along the minor axis to reduce a width of the support cushion along the minor axis. 
     
     
         9 . The dressing of  claim 1 , wherein at least a portion of each of the at least two perforations is curved. 
     
     
         10 . The dressing of  claim 1 , further comprising a plurality of perforations defined in the reservoir to enable removal of selected portions of the reservoir. 
     
     
         11 . The dressing of  claim 1 , wherein the support cushion further comprises a hydrophobic barrier. 
     
     
         12 . The dressing of  claim 1 , further comprising a biocompatible adhesive for securing the support cushion around the wound. 
     
     
         13 . The dressing of  claim 1 , wherein the reservoir comprises a first hydrophilic layer, a non-stretchable mesh or scrim, and a second hydrophilic layer. 
     
     
         14 . The dressing of  claim 1 , wherein the cover comprises a breathable material. 
     
     
         15 . The dressing of  claim 14 , wherein a vent is defined in the reservoir, the vent permitting humidity over the wound to escape through the vent and the cover. 
     
     
         16 . The dressing of  claim 1 , further comprising a biocompatible adhesive securing the cover to the reservoir. 
     
     
         17 . The dressing of  claim 1 , further comprising a biocompatible adhesive for securing the cover to the support cushion. 
     
     
         18 . The dressing of  claim 1 , further comprising means for repeatedly attaching and detaching the cover to the support cushion so that the wound is viewable without entirely removing the dressing. 
     
     
         19 . A method for protecting a wound, the method comprising:
 providing a support cushion configured to surround the wound, the support cushion having sidewalls defining a major axis and a minor axis, the support cushion including at least two perforations that traverse the sidewalls at offset locations;   surrounding the wound with a support cushion;   applying a reservoir over the support cushion; and   transferring fluid from the wound to the reservoir.   
     
     
         20 . The method of  claim 19 , wherein a plurality of additional perforations are defined in the support cushion, the method further comprising reducing a size of the support cushion along the major axis by removing selected portions of the support cushion. 
     
     
         21 . The method of  claim 19 , wherein the reservoir includes a plurality of perforations, the method further comprising reducing a size of the reservoir by removing a selected portion of the reservoir along at least one perforation of the plurality of perforations defined in the reservoir. 
     
     
         22 . The method of  claim 19 , wherein the support cushion includes a stepped profile that defines a ledge and a recess, the method further comprising fitting the reservoir within the recess so that the reservoir engages the ledge and is suspended over the wound. 
     
     
         23 . The method of  claim 22 , wherein the support cushion comprises a hydrophobic portion that defines the recess and a hydrophilic portion that defines the ledge. 
     
     
         24 . The method of  claim 19 , further comprising securing a cover to the support cushion with a biocompatible adhesive. 
     
     
         25 . A kit for a dressing for use in protecting a wound, the kit comprising:
 a support cushion configured to surround the wound, the support cushion having sidewalls defining a major axis and a minor axis, the support cushion including at least two perforations that traverse the sidewalls at offset locations;   a reservoir configured to be applied over the support cushion;   a backing upon which the support cushion and reservoir are mounted; and   instructions for use printed on the backing, the instructions for use describing steps for assembling the dressing.
