Patent ID: 7731702

Claim:
A method of draining a wound, comprising: applying a self-adhering covering of moisture permeable gel without the use of an additional adhesive to a healthy skin surface outside of a wound area to form a wound cavity, the gel covering extending over the wound area without extending into the wound area, the gel covering adhering to the healthy skin surface outside the wound area, the gel covering remaining above the healthy skin surface without extending below the healthy skin surface, the wound cavity communicating with tubing having an inner conduit, a distal end and a proximal end, applying a porous material extending across an opening to the wound cavity below the distal end of the tubing so that material drawn from a wound into the tubing passes through the porous material, applying a reduced pressure to the inner conduit to draw material from the wound into the tubing, and collecting material drawn into the tubing from the wound in a container connected to a proximal end portion of the tubing.
