Hydrogel dressing is a medical dressing based on hydrogels, three-dimensional hydrophilic structure. [1] The insoluble hydrophilic structures absorb polar wound exudates and allow oxygen diffusion at the wound bed to accelerate healing. [2]
Self-healing hydrogels are a specialized type of polymer hydrogel. A hydrogel is a macromolecular polymer gel constructed of a network of crosslinked polymer chains. Hydrogels are synthesized from hydrophilic monomers by either chain or step growth, along with a functional crosslinker to promote network formation.
It contains gel forming agents such as carboxymethylcellulose, gelatin and pectin. When the dressing is in contact with the wound, the wound discharge are retained to form gel which provides moist environment for wound healing. It protects the wound from bacterial contamination, absorbs wound discharge, and digests necrotic tissues.
“Alongside panthenol, which helps speed up regeneration and repair while moisturizing the skin, research shows that glycerin-based hydrogels help control infections in wounds, which lasers ...
[77] [78] [79] Hydrogels with reversible chemistry are required to allow for fluidization during injection/printing followed by self-healing of the original hydrogel structure. [80] Investigate cell biomechanical functions combined with holotomography microscopy; Provide absorption, desloughing and debriding of necrotic and fibrotic tissue
Traumagel is an algae-derived gel that comes in a pre-filled syringe and requires no manual pressure on the wound to create a blood clot, according to the company.
