Abstract
A wound treatment apparatus is provided for treating tissue damage, which comprises a fluid impermeable wound cover sealed over a site for purposes of applying a reduced pressure to the site. The apparatus also can include a cover with protrusions on its surface for purposes of monitoring pressure at the site. One or more sensors can be positioned under the cover to provide feedback to a suction pump controller. The apparatus can have a miniature and portable vacuum source connected to the wound cover.
Claims39
A method of treating a wound, comprising:
- positioning a wound dressing apparatus over the wound, comprising positioning an at least liquid impermeable cover over the wound so as to create a substantially sealed space between the cover and the wound;
- applying reduced pressure to the space between the cover and the wound;
- and
- monitoring the reduced pressure in the space between the cover and the wound by visually observing a change in color or a change in a shade of a color of at least a portion of the wound dressing apparatus in response to the amount of reduced pressure applied to the sealed space.

A method of treating a wound, comprising:
- positioning a wound dressing apparatus over the wound, comprising positioning an at least liquid impermeable cover over the wound so as to create a substantially sealed space between the cover and the wound;
- applying reduced pressure to the space between the cover and the wound so that at least a portion of the cover contracts in the direction of the wound;
- and
- monitoring the reduced pressure in the space between the cover and the wound by visually observing a plurality of protrusions supported by the wound dressing apparatus, the protrusions being made of a material that is a different color than a color of at least a portion of the cover.
1 more element
A method of treating a wound, comprising:
- positioning a wound treatment apparatus comprising a wound cover over a wound so as to create a substantially sealed space between the cover and the wound;
- applying negative pressure to the wound with a vacuum source to draw wound exudate away from the wound;
- and
- monitoring wound treatment with a plurality of monitors spaced along a layer of the apparatus, wherein each of the plurality of monitors is configured to provide a visual indication of a condition within the wound cover.

A method of treating a wound, comprising:
- positioning a wound dressing apparatus over the wound, comprising positioning an at least liquid impermeable cover over the wound so as to create a substantially sealed space between the cover and the wound;
- and
- applying reduced pressure to the space between the cover and the wound;
- wherein applying a reduced pressure to a space between the cover and the wound comprises supplying reduced pressure from a vacuum source that is supported by the cover and located within a periphery of the wound cover.
