Abstract:
1. A gas delivery tissue dressing system for supplying one or more predetermined gases to a target environment, comprising; a top layer of non-permeable material; a reservoir; a bottom layer of permeable film providing control of gas diffusion in and out of the reservoir; a first seal sealing the top and bottom layers along an outer perimeter where the top and bottom layers meet; and packaging made from non-permeable material; wherein the reservoir is formed by the sealing of the top and bottom layers, the reservoir holding a volume of one or more first predetermined gases at concentrations at ambient levels and the package is hermetically sealed forming an internal volume receiving the entire reservoir, the packaging is charged with the one or more second predetermined gases above ambient levels then hermetically sealed and the second predetermined gases diffuse into the reservoir via the bottom layer causing the first predetermined gases to reach a concentration level higher than the ambient level and wherein the system does not generate gas.
