Self-gelling wound contact materials with iodine delivery

Abstract

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.
