Abstract
Fluid collection apparatuses and methods of use in negative pressure therapies are provided.
Claims33
A fluid collection apparatus for negative pressure wound therapy comprising
- a collection vessel,
- a first fluid defining member configured to be in fluid communication with a source of negative pressure,
- a first impeding element positioned at a first end of the first fluid defining member,
- a second impeding element positioned at a second end of the first fluid defining member, and
- a second fluid defining member defining a pathway for dispensing fluid drawn from a wound site of a patient during negative pressure wound therapy into a collection region of the collection vessel;
- and
- wherein the first impeding element impedes fluid dispensed within the collection region from entering a first end of the first fluid defining member and the source of negative pressure, and the second impeding element impedes fluid dispensed within the collection region from entering a second end of the first fluid defining member and the source of negative pressure.

A multi-orientation fluid collection apparatus for negative pressure wound therapy comprising:
- a) a collection vessel comprising a first side and a second side,
- b) a cover connected to the first side of the collection vessel,
- c) a first fluid pathway in fluid communication with a source of negative pressure, the first fluid pathway positioned between:
- (i) a first impeding element positioned at an interior of the cover or interior of the first side of the collection vessel and a
- (ii) second impeding element positioned at an interior of the second side of the collection vessel, wherein the first impeding element and the cover or first side of the collection vessel are in substantially fluid tight communication, and wherein the second side is optionally opposing the first side;
- d) a filter positioned within the first fluid defining member and between the first impeding element and the second impeding element, and
- e) a second fluid pathway for introducing exudate into the collection vessel.

An orientation independent apparatus connected to a source of negative pressure for collecting wound exudate, the apparatus comprising
- a collection vessel;
- a first fluid pathway comprising a first and a second end with impeding elements at the first and second ends, said first fluid pathway and a first side of the apparatus in fluid tight or substantially fluid tight communication with the source of negative pressure;
- and
- a second fluid pathway for drawing fluid from a wound site into the apparatus.
