Abstract

A wound dressing system comprising a wrap and a frangible ampoule is provided. The wrap is configured to contact/surround a wound site and includes an oxygen catalyst. The ampoule includes an oxygen precursor. The catalyst and precursor are configured to form oxygen when combined. A wound dressing system including a container is also provided that includes a powder, wrap, and frangible ampoule. The powder is disposed within the container, which is configured to allow the powder to be dispersed onto a wound site when activated. The wrap, which may include an oxygen catalyst, is also disposed in the container and is configured to contact/surround the wound site. The ampoule, also disposed in the container, includes a liquid containing an oxygen precursor. The liquid is configured to contact the wrap when the container is activated. Further, the catalyst and precursor are configured to form oxygen when combined.
