Flat-hose assembly for wound drainage system
First Claim
Patent Images
1. A flat-hose assembly having a proximal end and a distal end adapted for use with a negative pressure wound drainage system, the flat-hose assembly comprising:
- a top layer;
a bottom layer forming an opening at the distal end of the flat-hose assembly allowing exudates of a wound to flow into the flat-hose assembly; and
a filter layer disposed between the top layer and the bottom layer, the filter layer including pores that allow the exudates to flow through the filter layer and between the bottom layer and the top layer;
wherein the top and bottom layer form a seal area along a periphery of the top layer and the bottom layer sealing the filter layer therebetween.

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.

15. A flat-hose assembly adapted for use with a negative pressure wound drainage system, the flat-hose assembly having a proximal end and a distal end and comprising:
-
a top layer forming a first opening and a second opening therethrough at the proximal end of the top layer, the openings being adapted to apply negative pressure to the flat-hose assembly; a bottom layer forming a third opening at the distal end of the bottom layer, the third opening allowing exudates of a wound to flow into the flat-hose assembly; a filter layer disposed between the top layer and the bottom layer, the filter layer being adapted to prevent contact between the top layer and the bottom layer other than at a periphery of the top layer and the bottom layer, the filter layer including pores that allow the exudates to flow through the filter layer and between the bottom layer and the top layer, the filter layer further adapted to trap large particles of exudates from a wound within the flat-hose assembly, the top layer and the bottom layer forming a seal area along a periphery of the top layer and the bottom layer sealing the filter layer therebetween; a first hose fitting protruding through a first opening formed in the distal end of the top layer adapted to connect the flat-hose assembly to the negative pressure wound drainage system; a second hose fitting protruding through a second opening formed in the distal end of the top layer adapted to connect the flat-hose assembly to the negative pressure wound drainage system; and an adhesive adapted to connect the flat-hose assembly to a wound dressing of the wound drainage system. - View Dependent Claims (16, 17, 18)
