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.
Claims41
A fluidic connector for providing aspiration and irrigation to a wound site, comprising:
- a proximal end and a distal end and an elongate length extending therebetween;
- a top layer, a bottom layer and an intermediate layer each constructed from a flexible, liquid impermeable material and adhered to one another, wherein each of the layers has a proximal end and a distal end and elongate portions extending therebetween;
- an upper fluid passage between the top layer and the intermediate layer;
- a lower fluid passage between the intermediate layer and the bottom layer;
- one or more openings at or near a distal end of the upper fluid passage;
- and
- one or more openings at or near a distal end of the lower fluid passage;
- wherein each of the upper and lower fluid passages comprises a flexible, elongate spacer material between corresponding layers;
- and
- wherein one of the upper and lower fluid passages is configured to provide aspiration to the wound site, and the other of the upper and lower fluid passages is configured to provide irrigation fluid to the wound site.

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, the fluidic connector comprising:
- 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 defining an aspirant channel, wherein at least one aspiration opening at or near the distal end of the first layer of flexible film is configured to transmit aspiration to the wound, and
- a third layer of flexible film sealed around a perimeter to the second layer of flexible film, thereby defining an irrigation channel, wherein at least one irrigation opening at or near the distal end of the third layer is configured to transmit irrigation fluid to the wound,
- wherein each of the aspirant channel and irrigation channel comprises a flexible, elongate spacer material between corresponding layers.

A fluidic connector for providing aspiration and irrigation to a wound site, comprising:
- a top layer and a bottom layer each constructed from a flexible, liquid impermeable material, wherein each of the layers has a proximal end and a distal end and elongate portions extending therebetween, and wherein each of the layers has a left edge and a right edge and a center portion therebetween;
- a left seal extending along the length of the left edges of the top and bottom layers, a right seal extending along the length of the right edges of the top and bottom layers, and a middle seal extending along at least a portion of the length of the center portions of the top and bottom layers;
- a left fluid passage between the top and bottom layers, further defined by the left seal and the middle seal;
- a right fluid passage between the top and bottom layers, further defined by the middle seal and the right seal;
- one or more openings in the bottom layer at or near a distal end of the left and right fluid passages;
- and
- at least one applicator portion attached to or integral with the bottom layer at a distal end of the bottom layer;
- wherein each of the left and right fluid passages comprises a flexible, elongate spacer material between the top and bottom layers;
- and
- wherein one of the left and right fluid passages is configured to provide aspiration to the wound site, and the other of the left and right fluid passages is configured to provide irrigation fluid to the wound site.
A fluidic connector for providing aspiration and irrigation to a wound site, comprising:
- a proximal end and a distal end and an elongate length extending therebetween;
- a first fluid passage and a second fluid passage positioned side-by-side and joined together along at least a portion of the elongate length, each of the fluid passages containing an elongate spacer material;
- and
- at least one applicator portion at the distal end;
- wherein the first fluid passage is configured to provide aspiration to a wound site, and the second fluid passage is configured to provide irrigation fluid to the wound site.
