Abstract: A wound dressing including a nonwoven absorbent layer including a layer of fabric comprising gel-forming fibers. The absorbent layer is gathered in a longitudinal direction by stitching through the layer of fabric using one or more resilient threads or yarns and an inelastic thread or yarn. The resilient and inelastic threads or yarns gather the layer of fabric so that the layer of fabric in use is configured to maintain close conformability with a wound during movement, and to elongate by 35% to 85% and then recover.

Abstract: A method of manufacturing a laminated dressing that includes providing a lower layer having a fiber material that directly contacts a patient's skin and a wound area, providing an upper layer that has a foam or foam-like material that absorbs exudate and moisture, and binding the fiber-based lower layer and the foam-based upper layer with a binder layer comprising a binder material, the binder layer including a series of perforations. The perforations in the binder layer are formed by removing material from the binder layer with a pattern coated adhesive sheet prior to binding the fiber-based lower layer and the foam-based upper layer.

Abstract: Certain embodiments relate to a soft odor barrier material in a medical device. The soft odor barrier material includes an elastomer and an antiblocking agent. In certain forms, the antiblocking agent imparts an interior rough surface having an arithmetic mean surface roughness (Ra) not less than 0.1 μm. In certain forms, the antiblocking agent is non-blocking upon folding and packaging.

Abstract: An integrated system for assessing wound exudates from the wound of a patient is described. The system may contain functionality to detect, process and report various wound parameters. The system also may make treatment determinations based on these findings. The system may detect one or more physiological values of the wound exudates from the wound of the patient. The system may means for comparing the one or more detected physiological values to predetermined physiological values in order to obtain a comparison result in real time. The system may include a processor 15 which provides an electronic signal based on a comparison result in which the electronic signal may correspond to guidelines for treating the wound 13. The system may be integrated with other wound treatment devices, such as negative pressure wound therapy devices (NPWT) 9.
