Abstract
A flat-hose assembly has a proximal end and a distal end adapted for use with a negative pressure wound drainage system. The flat-hose assembly comprises a top layer, a bottom layer, and a filter layer. The bottom layer forms an opening at the distal end of the flat-hose assembly to allow exudates of a wound to flow into the flat-hose assembly. The filter layer is disposed between the top layer and the bottom layer. The top and bottom layer form a seal area along a periphery of the top layer and the bottom layer to seal the filter layer therebetween.
