Abstract
A bandage is provided for use with a wound having a wound surface. The bandage is connectable to a vacuum source and may include a flexible cover positioned over the wound and a collar coupled to the cover. The cover includes a port and is configured to seal to a patient's healthy skin surrounding the wound. The collar may be coupled to the cover and include a passageway in communication with the port of the cover. The passageway is configured to receive at least a portion of a tube in communication with the vacuum source. The bandage may also include a sealer coupled to the collar. The sealer may be configured to provide a substantially airtight seal between the tube and the passageway to create a sealed environment capable of maintaining a negative pressure between the cover and the wound surface.
