Abstract
Disclosed herein are several embodiments of a negative pressure apparatus and methods of using the same in the treatment of wounds. Some embodiments are directed towards improved fluidic connectors configured to transmit irrigation fluid and to apply aspiration to a wound, for example using softer, kink-free conformable layers. Some embodiments may comprise a first channel for delivering irrigation fluid to the wound and a second channel for transmitting negative pressure and removing fluid comprising irrigation fluid and wound exudate from the wound, wherein the channels comprise a flexible spacer material. Some embodiments are directed toward an irrigation manifold attachable to or incorporated as part of a distal end of an irrigation and aspiration fluidic connector.
Claims20
A system for treatment of a wound, comprising:
- a sealing membrane for covering the wound;
- a wound filler adapted to be positioned in the wound;
- and
- a fluidic connector capable of being operably associated, in use, with the wound;
- a first conduit provided at a proximal end of a first fluid channel of the fluid connector and in fluid communication with the first fluid channel of the fluid connector;
- a second conduit provided at a proximal end of a second fluid channel of the fluid connector and in fluid communication with the second fluid channel of the fluid connector;
- and
- one or more therapy units configured to be placed in fluid communication with the fluidic connector;
- wherein:
- the fluidic connector comprises:
- a proximal end and a distal end and an elongate length extending therebetween;
- a first layer of flexible film;
- a second layer of flexible film sealed around a perimeter to the first layer of flexible film, thereby forming the first fluid channel of the fluidic connector;
- a first opening at or near a distal end of the first fluid channel configured to be in communication with the first fluid channel;
- a third layer of flexible film sealed around a perimeter to the second layer of flexible film, thereby forming the second fluid channel of the fluidic connector;
- and
- a second opening at or near a distal end of the second fluid channel configured to be in communication with the second fluid channel;
- each of the first fluid channel and the second fluid channel comprises a flexible, elongate spacer material between corresponding layers;
- the one or more therapy units is configured to be placed in fluid communication with the first conduit and the first fluid channel of the fluidic connector and to provide aspiration to the wound through the first conduit and the first fluid channel of the fluidic connector;
- and
- the one or more therapy units is configured to be placed in fluid communication with the second conduit and the second fluid channel of the fluidic connector and to provide a fluidic connection to the wound through the second conduit and the second fluid channel of the fluidic connector;
- wherein the second conduit is not in fluid communication with the first fluid channel and the first conduit is not in fluid communication with the second fluid channel;
- wherein the first conduit is positioned to extend into the proximal end of the first fluid channel and extend outwardly from the proximal end of the first fluid channel, the first conduit positioned between the first layer and the second layer, wherein the second conduit is positioned to extend into the proximal end of the second fluid channel and extend outwardly from the proximal end of the second fluid channel, the second conduit is positioned between the second layer and the third layer, the first conduit not in contact with the third layer and the second conduit not in contact with the first layer.
