Patent number: 8083712Abstract: 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.Type: GrantFiled: March 20, 2007Date of Patent: December 27, 2011Assignee: Neogen Technologies, Inc.Inventors: Lydia B.

Patent number: 8034038Abstract: A portable closed wound drainage system that uses a pouch shaped dressing which is inserted into a wound. At least a portion of the outer surface of the pouch 1 is porous to allow exudates to enter. Exudates are removed from the pouch by flexible tubing which is secured inside the pouch at one end, and secured at the other end to a portable drain/suction unit. The pouch contains porous material, and may optionally contain beads and fillers which are antibacterial in nature. The tubing can have a single or multi-lumen structure with perforations in the side walls of the end of the tube that is inserted in the pouch to allow body fluids to enter laterally. The portable drain/suction unit is preferably a portable battery powered device. The pouch and the tube are sealed by a flexible sealing material which is applied to the outer surface of the skin around the periphery of the pouch and the tubing as it exits the pouch.Type: GrantFiled: March 13, 2009Date of Patent: October 11, 2011Assignee: NeoGen Technologies, Inc.Inventors: John J.
