Wound dressings and systems with remote oxygen generation for topical wound therapy and related methods

A system comprising:

• a dressing for facilitating delivery of oxygen to the target tissue, the dressing comprising:
• a first manifold that defines a plurality of gas passageways and is configured to allow communication of oxygen to the target tissue;
• a gas-occlusive layer configured to be disposed over the first manifold and coupled to tissue surrounding the target tissue such that an interior volume is defined between the gas-occlusive layer and the target tissue;
• and
• the gas-occlusive layer limits escape of oxygen from the interior volume between the gas-occlusive layer and the tissue surrounding the target tissue;
• a container outside the interior volume, the container having a sidewall that defines a chamber configured to be in fluid communication with the interior volume;
• and
• an oxygen-generating material disposed within the chamber of container and configured to release oxygen when exposed to water.

A method comprising:

• coupling dressing to a patient's tissue, the dressing comprising:
• a manifold that defines a plurality of gas passageways and is configured to allow communication of oxygen to the target tissue;
• a gas-occlusive layer configured to be disposed over the manifold and coupled to tissue surrounding the target tissue such that;
• an interior volume is defined between the gas-occlusive layer and the target tissue;
• and
• the gas-occlusive layer limits escape of oxygen from the interior volume between the gas-occlusive layer and the tissue surrounding the target tissue;
• and
• a port coupled to the gas-occlusive layer, wherein the port is configured to be releasably coupled to an oxygen-generating device and to allow fluid communication of oxygen between the oxygen-generating device and the interior volume;
• coupling the dressing to a container, wherein the container comprises:
• a sidewall that defines a chamber configured to be in fluid communication with the interior volume of the dressing;
• and
• an oxygen-generating material disposed within the chamber of container and configured to release oxygen when exposed to water;
• and
• introducing oxygen into the interior volume of the dressing.
