Abstract

A wound shield for exudate management may include a conformable frame to circumscribe a wound. The conformable frame may be formed of material for absorbing wound exudate. Exudate absorbing material may also be one of two or more layers of material forming the conformable frame. The layers may be arranged to keep the exudate absorbing layer at some selected distance from a patients skin. Any suitable dressing may be secured over the conformable frame providing separation between the wound and the dressing. The wound frame may provide pressure relief around a wound or pressure sore to permit healing. The conformable frame may be wrapped, in a spiral, around a wound providing an increasing pressure relief by increasing distance from the wound. A conformable frame may be composed of one or more layers of any suitable material and may include adhesive on one or more surfaces to secure the frame to the wound site and or to secure the dressing to the conformable frame. One layer of the two or more layers of material forming the conformable frame may be a wicking or conduit material that draws exudate from the wound and transports the exudate to any suitable media for exudate storage. The exudate storage may be one or more layers of a dressing covering the wound site, or it may be a removable reservoir.

Claims

1. A wound shield comprising:

a conformable frame circumscribing the wound in a spiral forming two or more wraps;

a cover engaging the conformable frame forming an enclosed wound space within the conformable frame spiral.

2. The wound shield of claim 1 wherein the conformable frame further comprises one or more absorbent layers with the absorbent layer adjacent the wound.

3. The wound shield of claim 1 wherein each wrap of the two or more wraps of the conformable frame have different heights, with the lowest height adjacent the wound and increasing height away from the wound.

5. The wound shield of claim 1 wherein the conformable frame has two or more zones and a first zone is adjacent the wound, the first zone comprising two or more layers with the layer adjacent the wound being absorbent.

6. The wound shield of claim 3 wherein the conformable frame has two or more zones and a first zone comprises the first wrap and is adjacent the wound, the first zone comprising two or more layers with the layer adjacent the wound being absorbent.

7. The wound shield of claim 1:

wherein the conformable frame has two or more zones and a first zone is adjacent the wound, the first zone comprising two or more layers with the layer adjacent the wound being absorbent; and

wherein a portion of the cover is transparent and the non-transparent portion is absorbent.

4. A method of protecting one or more wounds comprising:

applying a first end of a conformable frame proximate a wound to be protected;

circumscribing the wound to be protected with the conformable frame;

wrapping the conformable frame around the circumscribed wound in a spiral; and

securing a cover to the spiral wrapped conformable frame enclosing a space adjacent the wound to be protected.
