Cutting template for a negative pressure wound therapy drape

A cutting template for use with a negative pressure wound therapy system, the cutting template comprising:

• a top surface configured to interface with a drape;
• a bottom surface configured to interface with a dressing;
• a first annular surface contiguous with the bottom surface and extending orthogonally from the bottom surface towards the top surface, the first annular surface defined by a first diameter;
• a second annular surface contiguous with the top surface and extending orthogonally from the top surface towards the bottom surface, the second annular surface defined by a second diameter different from the first diameter;
• and
• a lip surface contiguous with the first annular surface and the second annular surface.

A cutting template for use with a negative pressure wound therapy system, the cutting template comprising:

• a substantially rigid body, the body comprising:
• a top surface configured to engage a drape layer;
• a bottom surface configured to engage a dressing layer;
• a height defined between the top surface and the bottom surface, the height configured to create a gap between the drape layer and the dressing layer;
• a first annular surface disposed between the top surface and the bottom surface;
• and
• a second annular surface disposed between the top surface and the bottom surface;
• and
• a recess disposed substantially about a perimeter of the body;
• wherein the recess is configured to receive an edge of a cutting tool so that an opening is formed in the drape layer when the edge is traversed about the perimeter, and wherein at least part of the recess is formed between the first annular surface and the second annular surface.

• a recess disposed substantially about a perimeter of the body;
• wherein the recess is configured to receive an edge of a cutting tool so that an opening is formed in the drape layer when the edge is traversed about the perimeter, wherein one of the first annular surface and the second annular surface is inset relative to the other of the first annular surface and the second annular surface to form the recess.

A kit for use with a negative pressure wound therapy device, the kit comprising:

• a package defining a sterilized interior environment;
• a dressing layer disposed within the sterilized interior environment;
• a drape layer disposed within the sterilized interior environment;
• and
• a cutting template disposed within the sterilized interior environment;
• wherein the cutting template comprises a top surface, a bottom surface, and a recess disposed about a perimeter of the cutting template, the recess configured to receive an edge of a cutting tool, and wherein:
• the top surface is configured to interface with the drape layer,
• the bottom surface is configured to interface with the dressing layer, and
• the cutting template further comprises a first annular surface contiguous with the bottom surface and extending orthogonally from the bottom surface towards the top surface, and a second annular surface contiguous with the top surface and extending orthogonally from the top surface towards the bottom surface.

A method of cutting a drape for use with a negative pressure wound therapy device, the method comprising the steps of:

• placing a cutting template on a dressing;
• placing a drape over the cutting template such that the drape covers the cutting template and the dressing;
• pressing an implement against the drape such that the implement presses the drape towards the cutting template, thereby causing the drape to be cut;
• rotating, after pressing the implement against the drape such that the implement presses the drape towards the cutting template, the implement about the cutting template thereby causing a cutout to be separated from the drape and an aperture to be simultaneously formed in the drape;
• removing the cutout from the aperture;
• sealing a negative pressure lumen of the negative pressure wound therapy device about the aperture;
• rotating, prior to placing the cutting template on the dressing, the cutting template along a perimeter of a wound bed;
• and
• placing, prior to placing the cutting template on the dressing and after rotating the cutting template along the perimeter of the wound bed, the dressing over at least a portion of the wound bed.
