Publication number: 20230136007Abstract: Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing comprises a cover layer, an acid providing layer and a nitrite providing layer. The acid providing layer comprises acidic groups and may be hydrogel or Xerogel. The nitrite providing layer comprises a nitrite salt. The wound dressing may also include other layers, one or more acquisition distribution layers or masking layers. The masking layers can at least partially prevent visualization of the layer below the masking layer. Nitrite ions of the nitrite providing layer may react with the acidic groups of the acid providing layer to generate nitric oxide. The acid providing layer further includes one or more material layers to reduce the adhesiveness of the acid providing layer. The acid providing layer can also include perforations.Type: ApplicationFiled: April 1, 2021Publication date: May 4, 2023Inventors: Maria Aspioti, Varuni Rachindra Brownhill, Anthony Colin Dagger, Daniel James Fitzgerald, Nicholas Charlton Fry, Latifa Giaffar, Victoria Jody Hammond, Edward Yerbury Hartwell, Neill John Rawson, Anna Elizabeth Smith, Liam Thomson, Iain Webster

Publication number: 20220160931Abstract: Disclosed embodiments relate to wound care materials and methods that comprise a self-gelling composition, configured to form a gel upon contacting fluid. The self-gelling composition is a substantially homogeneous mixture, and comprises fluid-absorbent particles loaded with iodine-based antimicrobial agent, a dehydrated hydrogel powder, and a polymer base, configured to allow dispensing the self-gelling composition from a syringe or tube and to prevent the self-gelling composition from gelling prior to contacting fluid. The gel performs one or more of the following tasks during a wear time, when applied at the wound: absorbing fluid or exudate, releasing iodine-based antimicrobial agent, achieving antimicrobial activities at the wound, remaining structurally integral and cohesive, protecting the wound from exposure to microorganisms, and facilitating healing. After a wear time of at least three days, the gel can be removed in two pieces or less and leave less than 5% residue by weight.Type: ApplicationFiled: April 1, 2020Publication date: May 26, 2022Inventors: Anthony Colin Dagger, Nicholas Charlton Fry, Victoria Jody Hammond

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
