An exemplary wound dressing generally includes a wound-contacting layer and a sensor array. The sensor array is positioned distally of the wound-contacting layer, and generally includes a substrate, a first sensor positioned on the substrate, and a second sensor positioned on the substrate. The second sensor surrounds the first sensor, and each of the first sensor and the second sensor has a corresponding and respective electrical characteristic that varies in response to contact with wound exudate.

A partially transparent dressing includes a fluid management core having a first side and a second, wound-facing side. The fluid management core includes an absorbent material and a plurality of optically transparent windows. The dressing includes a barrier layer coupled to the first side and a patient interface layer coupled to the second side. A fluid communication port is disposed in the second side. An opening is disposed in the patient interface layer. The opening is configured to receive fluid from a wound.

A negative pressure wound therapy (NPWT) dressing is formed from a transparent polymer and includes large-diameter passageways through the dressing for providing suction and irrigation to a wound. The NPWT dressing is formed so as to be non-compressible and non-collapsible to provide low resistance and maintain positive surface pressure at low vacuum settings. The NPWT dressing includes a docking port and suction dome for coupling the dressing to a suction source and an irrigation source. The NPWT dressing may be customizable, disposable, and/or expandable to treat a variety of wounds.

The invention relates to a method for assisting a user in capturing a digital image of a transparent wound dressing preferably for monitoring the healing process of a wound dressed with and visible through the transparent wound dressing, to a method for assisting a user in reviewing digital images of a transparent wound dressing, and to corresponding computer programs and computer readable media. Also, a system for assisting a first user in capturing a digital image of a transparent wound dressing and for assisting a second user in reviewing digital images of a transparent wound dressing is described. In order to enhance both user friendliness and reliability of the digital image acquisition, it is proposed to superimpose an overlay image with visual indications on the digital images currently obtained.
