Abstract
A wound treatment appliance is provided for treating all or a portion of a wound. In some embodiments, the appliance comprises a cover or a flexible overlay that covers all or a portion of the wound for purposes of applying a reduced pressure to the covered portion of the wound. In other embodiments, the wound treatment appliance also includes a vacuum system to supply reduced pressure to the site of the wound in the volume under the cover or in the area under the flexible overlay. Methods are provided for using various embodiments of the invention.
Claims26
A wound therapy device, comprising:
- a cover layer configured for positioning over a wound to create an area in which a reduced pressure may be maintained over the wound;
- a port on the cover layer, the port defining a fluid passage for fluid coupling with a reduced pressure supply conduit;
- and
- a filter at the port and positioned relative to the fluid passage, the filter dimensioned to prevent passage of wound exudate through the fluid passage of the port.
A wound therapy device, comprising:
- a cover positionable over a wound and configured to maintain reduced pressure under the cover at the site of the wound;
- a gasket positionable around a perimeter of the wound;
- and
- a source of reduced pressure configured to provide reduced pressure to the cover so that the volume under the cover at the site of the wound is supplied with reduced pressure;
- wherein the cover is removably attachable to the gasket to form an operable seal.
A reduced-pressure treatment system for treating a tissue site on a patient, the system comprising:
- an interface member sized and configured to be placed in contact with the tissue site;
- a gasket positionable around a perimeter of the tissue site;
- a cover positionable over the interface member and releasably sealable to the gasket, wherein the cover is configured to create a sealed space between the cover and the tissue site;
- and
- a reduced-pressure source fluidly coupled to the sealed space to deliver reduced pressure to the tissue site.
A method of treating a wound, comprising:
- positioning a gasket over tissue surrounding a wound;
- removably sealing a wound cover to the gasket to create a sealed space between the cover and the wound;
- and
- applying reduced pressure to the sealed space to deliver reduced pressure to the wound.
