Abstract
A wound leakage collection device is described wherein a chamber provides a volume wherein wound leakage material can be removed from vacuum tubing and said device can be easily removed from a wound and a negative pressure source.
Claims37
A wound leakage containment device comprising:
- substantially hollow vacuum tubing having a wall, said wall having an external surface, an internal surface, a first end in fluid communication with a source of negative pressure, a second end in fluid communication with and directly connected to a source of wound leakage, and a perforated portion between the first end and the second end having one or more perforations extending through the wall between the internal surface and the external surface, the perforations being effective for permitting wound leakage to pass through the wall of said substantially hollow vacuum tubing responsive to negative pressure;
- a chamber for enclosing and maintaining a vacuum around the external surface of the perforated portion of said substantially hollow vacuum tubing;
- an absorbent material disposed within said chamber adjacent to the external surface of the perforated portion of said substantially hollow vacuum tubing;
- and one or more vapor-permeable plugs disposed in the internal surface of said substantially hollow vacuum tubing between the first end and the perforated portion thereof.

A method for containing leakage from a wound, comprising:
- applying a vacuum from a source of negative pressure to a first end of a substantially hollow tube having a first end and a second end, and a wall having an interior and an exterior surface, the second end being in fluid communication with directly connected to a source of wound leakage;
- collecting wound leakage flowing through the substantially hollow tube responsive to vacuum through one or more perforations in a portion of the wall of the substantially hollow tube extending therethrough, forming a perforated portion having an internal surface and an external surface, the external surface thereof being in contact with absorbent material disposed in a chamber enclosing and maintaining a vacuum around the exterior surface of the perforated portion of the substantially hollow tube;
- and one or more vapor-permeable plugs disposed within the substantially hollow tube between the one or more perforations and the source of negative pressure.
A wound leakage containment device comprising:
- a.) a substantially hollow conduit section having a conduit wall, the conduit wall having an external surface, an internal surface, the internal surface defining a passageway extending from a first conduit termination to a second conduit termination, the passageway containing no absorbent material or desiccant, the first conduit termination being configured for fluid communication with a source of negative pressure, the second conduit termination being configured for fluid communication with a source of wound leakage, and the substantially hollow conduit section containing a perforated portion, the perforated section having one or more perforations extending through the conduit wall, the perforations being configured to permit wound leakage fluid to flow through said perforations to the external surface;
- b.) a chamber sealingly enclosing the perforated portion for enclosing and maintaining a vacuum around the external surface of the perforated portion;
- c.) an absorbent material disposed within the chamber adjacent to the external surface of the perforated portion;
- and
- d.) one or more vapor-permeable plugs disposed in the passageway between the first conduit termination and the perforated portion.
