Method and apparatus for supplying gas to an area

摘要

Embodiments of the present invention are directed to various designs and packaging methods for a gas delivery device and materials for supplying one or more predetermined gases to a target area as well as to application specific opthamological embodiments. With regard to the gas delivery device, the device may include a reservoir, a gas diffusion portion for communicating gas from the reservoir and one or more predetermined gases at concentrations greater than atmospheric contained within the reservoir, wherein the device does not generate gas and may be packaged prior to use with the one or more predetermined gases.

主权项

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.
