A negative pressure wound therapy kit comprising:
- a wound dressing;
- and
- a sheet separate from the wound dressing, the sheet comprising:
- a film having a length between first and second opposing edges of the film and a width between third and fourth opposing edges of the film, the film comprising an adhesive surface and a non-adhesive surface;
- a plurality of fixation strips formed in the film, wherein each fixation strip of the plurality of fixation strips has a length equal to the length of the film, and wherein the plurality of fixation strips are configured to secure the wound dressing during use;
- a carrier layer provided on the non-adhesive surface of the film;
- a central protective layer provided on the adhesive surface of the film;
- a first outer protective layer and a second outer protective layer provided on the adhesive surface of the film, the first outer protective layer provided at or near the first opposing edge and the second outer protective layer provided at or near the second opposing edge, each of the first and second outer protective layers comprising a folded handle extending along the width of film;
- and
- a plurality of perforation lines each extending the length of the film and configured to facilitate separation of the fixation strips from the sheet.
