Apparatuses and methods for negative pressure wound therapy

A negative pressure wound therapy kit comprising:

• a wound dressing comprising a cover;
• and
• a fixation strip comprising:
• a wound sealing layer comprising a first adhesive surface, the first adhesive surface comprising a first adhesive,
• an adhering layer overlying the wound sealing layer and extending outward beyond the wound sealing layer, the adhering layer comprising a second adhesive surface comprising a second adhesive, and
• at least one protective liner removably adhered to the first adhesive surface of the wound sealing layer and/or the second adhesive surface of the adhering layer.

A method for sealing a wound dressing, the method comprising:

• positioning a wound dressing over a wound site and a periwound area surrounding the wound site, wherein the wound dressing comprises a cover;
• removing a central protective liner and a first outer protective liner from a first adhesive surface of a wound sealing layer and/or a second adhesive surface of an adhering layer of a fixation strip,
• wherein the fixation strip comprises the wound sealing layer comprising the first adhesive surface comprising a first adhesive, the adhering layer overlying the wound sealing layer and extending outward beyond the wound sealing layer, the central protective liner, the first outer protective liner, and a second outer protective liner, and
• wherein the adhering layer comprises the second adhesive surface comprising a second adhesive;
• positioning the fixation strip over the periwound area and partially over the wound dressing;
• removing the second outer protective liner from the first adhesive surface of the wound sealing layer and/or the second adhesive surface of the adhering layer;
• adhering the adhering layer of the fixation strip to the cover of the wound dressing;
• positioning an applicator of negative pressure on the cover of the wound dressing;
• and
• applying negative pressure to the wound site and the periwound area through the wound dressing for a period of time.

A method for sealing a wound dressing, the method comprising:

• cutting a wound dressing along a side portion of the wound dressing, the wound dressing comprising a cover;
• using a release handle of a first protective liner to remove the first protective liner from a first adhesive surface of a wound sealing layer of a fixation strip,
• wherein the fixation strip comprises the wound sealing layer comprising the first adhesive surface comprising a first adhesive, an adhering layer overlying the wound sealing layer and extending outward beyond the wound sealing layer, the first protective liner comprising the release handle of the first protective liner, and a second protective liner comprising a release handle of the second protective liner, and
• wherein the adhering layer comprises a second adhesive surface comprising a second adhesive;
• positioning the fixation strip over a periwound area surrounding a wound site;
• inserting the side portion of the wound dressing into the fixation strip between the wound sealing layer and the adhering layer;
• positioning the wound dressing over the wound site and the periwound area;
• using the release handle of the second protective liner to remove the second protective liner from the second adhesive surface of the adhering layer;
• adhering the adhering layer of the fixation strip to the wound dressing;
• positioning an applicator of negative pressure on the wound dressing;
• and
• applying negative pressure to the wound site and the periwound area through the wound dressing for a period of time.

An apparatus for sealing a wound site, the apparatus comprising:

• a sheet comprising a plurality of fixation strips and perforated portions, wherein each of the perforated portions is positioned between adjacent fixation strips, wherein each of the perforated portions comprises two perforated sections and a continuous cut section positioned between the two perforated sections, wherein the two perforated sections comprise a plurality of perforations separated by bridging portions that extend between adjacent fixation strips,
• wherein each of the plurality of fixation strips comprises:
• an adhering layer, and
• a first outer protective liner, a second outer protective liner and a central protective liner each removably adhered to the adhering layer, wherein the continuous cut section extends along at least an entire length of the central protective liner.
