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.

The fluidic connector of claim 1, wherein the spacer material of each of the upper and lower fluid passages comprises at least one of a 3D knitted or 3D fabric material, foam, a porous material and non-woven material. 3. The fluidic connector of claim 1, wherein the upper fluid passage is configured to provide aspiration to the wound and the lower fluid passage is configured to provide irrigation fluid to the wound. 4. The fluidic connector of claim 1, wherein the opening in the film of the top layer is upwardly facing. 5. The fluidic connector of claim 1, wherein the one or more openings in the film of the bottom layer comprises a plurality of microporous openings in the film of the bottom layer. 6. The fluidic connector of claim 1, further comprising a fluid distributing layer positioned below the one or more openings in the film of the bottom layer. 7. The fluidic connector of claim 1, wherein a distal end of the spacer material of the lower fluid passage extends distally beyond a distal end of the spacer material of the upper fluid passage. 8. The fluidic connector of claim 1, wherein the lower fluid passage is configured to provide irrigation fluid to the wound site and comprises a plurality of radially extending arms at a distal end thereof. 9. The fluidic connector of claim 8, further comprising a plurality of openings along each of the radially extending arms. 10. The fluidic connector of claim 8, wherein the radially extending arms comprise spacer material therein. 11.

The fluidic connector of claim 1, wherein the corresponding layers of each of the upper and lower fluid passages have side portions along sides of the elongate spacer material that are parallel to and adhered to each other. 15. The fluidic connector of claim 1, wherein the fluidic connector is soft to conform to a patient's skin along a length of the fluidic connector. 16. A fluidic connector for providing aspiration and irrigation fluid to a wound site, comprising: a proximal end, a distal end and an elongate length extending therebetween;a top layer, a bottom layer and an intermediate layer positioned between the top layer and the bottom layer, wherein each of the top, the bottom and the intermediate layers is constructed from a flexible, liquid impermeable film,wherein each of the top, the bottom and the intermediate layers extends along the elongate length from the proximal end to the enlarged distal end,wherein each of the top, the bottom, and the intermediate layers has an enlarged distal end and the enlarged distal ends of the upper, intermediate and bottom layers overlap with one another;an upper fluid passage defined by the intermediate layer being welded around a perimeter thereof to the top layer, the upper fluid passage comprising a first layer of a flexible spacer material positioned between the top layer and the intermediate layer, the upper fluid passage configured to provide the aspiration to the wound site;a lower fluid passage defined by the intermediate layer being welded around the perimeter to the bottom layer, the lower fluid passage comprising a second layer of the flexible spacer material positioned between the intermediate layer and the bottom layer, the lower fluid passage configured to provide irrigation fluid to the wound site;an opening in the film of the top layer within the enlarged distal end of the top layer for providing the aspiration from the upper fluid passage to the wound site; anda plurality of microporous openings in the film of the bottom layer within the enlarged distal end of the bottom layer for distribution of the irrigation fluid from the lower fluid passage to the wound site. 17. The fluidic connector of claim 16, wherein the flexible spacer material comprises at least one of a 3D knitted or 3D fabric material, foam, a porous material and non-woven material. 18. The fluidic connector of claim 16, wherein the distal end of the first layer of the flexible spacer material of the upper fluid passage extends distally beyond the opening in the top layer. 19. The fluidic connector of claim 16, wherein the distal end of the second layer of the flexible spacer material of the lower fluid passage extends distally beyond a distal end of the spacer material of the upper fluid passage. 20. The fluidic connector of claim 16, wherein the lower fluid passage comprises a plurality of radially extending arms at the distal end thereof. 21.
