NEGATIVE PRESSURE WOUND THERAPY DRESSING

摘要

A wound dressing suitable for use in negative pressure wound therapy system includes a cover layer adapted to establish a reservoir over a wound in which a negative pressure may be maintained. The cover layer includes an opening therein through which atmospheric gasses and wound exudates may pass through the cover layer. A vacuum port is affixed to the cover layer, and establishes a substantially fluid tight seal about the opening in the cover layer. The vacuum port includes a hollow interior in fluid communication with the opening in the cover layer and a connector to facilitate connection to a vacuum source. A packing member is affixed to the cover layer, to provide a wound dressing that may be applied in a single step process. The packing member is adapted to fill the wound and support the cover layer when a negative pressure is applied to the reservoir.

1. A wound dressing treatment system, which comprises:
a cover layer adapted to establish a reservoir over a wound in which a negative pressure may be maintained, the cover layer including an opening therein through which atmospheric gasses and wound exudates may pass through the cover layer; a vacuum port configured to be affixed to the cover layer to establish a substantially fluid tight seal about an opening formed in the cover layer, the vacuum port including a hollow interior configured to be in fluid communication with the opening in the cover layer, and a connector to facilitate connection to a vacuum source; and a packing member adapted to fill the wound and to support the cover layer when a negative pressure is applied to the reservoir, the packing member arranged in a continuous spiral configuration comprising a seam, the seam extending from a first end to a second end of the packing member.
