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.
Claims19
A reduced-pressure treatment apparatus, comprising:
- a dressing comprising:
- a foam layer comprises a first area and a second area, wherein the foam layer is configured for placement over a wound;
- and
- a cover layer positioned over the first area and second area, wherein the first area is sealed from the second area;
- a vacuum system comprising a reduced-pressure source configured to be in fluid communication with the dressing, wherein the vacuum system is configured to create reduced pressure at the first area that is separate from the reduced pressure at the second area, wherein the vacuum system further comprises a reduced-pressure source controller for controlling the reduced-pressure source;
- and
- a temperature monitoring system connectable with the vacuum system.
A reduced-pressure treatment apparatus, comprising:
- a dressing comprising:
- a foam layer comprises a first area and a second area, wherein the foam layer is configured for placement over a wound;
- and
- a cover layer positioned over the first area and second area, wherein the first area is sealed from the second area;
- and
- a vacuum system comprising a reduced-pressure source configured to be in fluid communication with the dressing, wherein the vacuum system is configured to create reduced pressure at the first area that is separate from the reduced pressure at the second area, wherein the vacuum system further comprises a reduced-pressure source controller for controlling the reduced-pressure source.
A reduced-pressure treatment apparatus for treating a wound comprising:
- a dressing comprising:
- a foam layer configured for placement over the wound, the foam layer segmented into areas, wherein the foam layer segmented into areas comprises a grid pattern of areas formed across a horizontal plane of the segmented foam layer;
- and
- a cover layer positioned over the segmented areas;
- and
- a vacuum system comprising a reduced-pressure source configured to be in fluid communication with the dressing, wherein the vacuum system is configured to create reduced pressure at the segmented areas, wherein the vacuum system further comprises a reduced-pressure source controller for controlling the reduced-pressure source.
