Publication number: 20210372975Abstract: Disclosed herein are devices, wound dressings and methods for determining the pH of fluid or a wound exudate at a wound. Example devices include a device comprising a surface configured to contact the fluid or wound and a pH indicator covalently bound thereto or applied to the surface, wherein the pH indicator has a first colour prior to contact with the fluid or the wound exudate and changes colour as a function of the pH of the fluid or wound exudate. Example devices include a device which indicates wound exudate loading within a wound dressing and wound dressing comprising an absorbent layer and a moisture indicator which indicates would exudate loading within the dressing, wherein the visibility of the moisture indictor changes as a result of a physical transformation of a first material within the dressing. Systems, devices, and methods are provided for monitoring wound status and progression by measuring pH levels indicated by pH-sensitive wound dressings.Type: ApplicationFiled: May 14, 2021Publication date: December 2, 2021Inventors: Sebastien Antoine Yves Cuvelier, Anthony Dagger, Nicholas Charlton Fry, Victoria Jody Hammond, Edward Yerbury Hartwell, John Kenneth Hicks, Alexander Speirs Laurie, Helene Anne Lecomte, Dorothy McCulloch, Ella Lynn Mumby, Mark Richardson, Carl Saxby, Rhianna Ward, Benjamin Wicks
