Gas based wound and tissue therapeutics
This invention provides articles of manufacture and bandages comprising compartments and layers comprising oxygen and other therapeutic gas storage forms and perfluorocarbons. This invention also provides for methods of delivering oxygen and other therapeutic gases to a tissue in a subject comprising a administering to the tissue a composition comprising a perfluorocarbon and a oxygen or therapeutic gas storage form, so as to thereby deliver oxygen or the therapeutic gas to the tissue.

127 . An article of manufacture comprising a therapeutic gas storage form and a perfluorocarbon, wherein when the therapeutic gas storage form is an oxygen storage form, it is in a first compartment and separated by a gas-permeable and liquid-impermeable material from the perfluorocarbon which is in a second compartment.
128 . The article of manufacture of claim 127 , wherein the oxygen storage form is hydrogen peroxide.
129 . The article of manufacture of claim 127 , wherein the therapeutic gas is nitric oxide, carbon monoxide, carbon dioxide, or hydrogen sulfide.
130 . The article of manufacture of claim 127 , wherein the perfluorocarbon is perfluoro-tert-butylcyclohexane.
131 . The article of manufacture of claim 127 , wherein the therapeutic gas storage form is in the form of a tablet.
132 . The article of manufacture of claim 127 , wherein the therapeutic gas storage form is in a first compartment and the perfluorocarbon is in a second compartment.
133 . The article of manufacture of claim 132 , wherein the first and second compartments are separated by a gas-permeable and liquid-impermeable material.
134 . The article of manufacture of claim 132 , wherein the first compartment further comprises a catalyst for releasing the therapeutic gas from the therapeutic gas storage form.
135 . The article of manufacture of claim 132 , in the form of a bandage, wherein a substantially gas-tight cover is on one side of the first compartment, the second compartment is on the opposite side of the first compartment, and a rayon mesh is on the side of the second compartment which is opposite first compartment.
136 . The article of manufacture of claim 127 , wherein the article of manufacture further comprises a second different therapeutic gas.
137 . A bandage comprising:
a) a substantially gas-tight cover;
b) a first layer comprising a therapeutic gas storage form;
c) a membrane;
d) a second layer comprising a perfluorocarbon; and
e) a rayon mesh
wherein the membrane separates the first and the second layers.
138 . The bandage of claim 137 , wherein the therapeutic gas is oxygen.
139 . The bandage of claim 137 , wherein the therapeutic gas storage form is hydrogen peroxide.
140 . The bandage of claim 137 , wherein the perfluorocarbon is perfluoro-tert-butylcyclohexane.
141 . The bandage of claim 137 , wherein the therapeutic gas storage form is in the form of a tablet.
142 . The bandage of claim 137 , wherein the membrane is gas-permeable and liquid-impermeable.
143 . The bandage of claim 137 , wherein the first layer further comprises a catalyst for releasing the therapeutic gas from the therapeutic gas storage form.
144 . A bandage comprising:
a) a substantially gas-permeable cover;
b) a layer comprising a perfluorocarbon; and
c) a rayon mesh.
145 . The bandage of claim 144 , wherein the perfluorocarbon is perfluoro-tert-butylcyclohexane.
146 . A method of delivering a therapeutic gas to a tissue in a subject comprising administering to the tissue a composition comprising a perfluorocarbon and a therapeutic gas storage form, wherein when the therapeutic gas storage form is an oxygen storage form, it is separated from the perfluorocarbon by a gas-permeable and liquid-impermeable material, so as to thereby deliver the therapeutic gas to the tissue.
147 . A method of delivering a therapeutic gas to a tissue in a subject comprising topically administering to the tissue a solid or semi-solid composition comprising a perfluorocarbon and a therapeutic gas storage form, wherein when the therapeutic gas storage form is an oxygen storage form, it is separated from the perfluorocarbon by a gas-permeable and liquid-impermeable material, so as to thereby deliver the therapeutic gas to the tissue.
148 . The method of claim 147 , wherein the oxygen storage form is hydrogen peroxide.
149 . The method of claim 147 , wherein the therapeutic gas is nitric oxide, carbon monoxide, carbon dioxide, or hydrogen sulfide.
150 . The method of claim 147 , wherein the perfluorocarbon is perfluoro-tert-butylcyclohexane.
151 . The method of claim 147 , wherein the therapeutic gas storage form is in the form of a tablet.
152 . The method of claim 147 , wherein the perfluorocarbon and the therapeutic gas storage form are separated by a gas-permeable and liquid-impermeable material.
153 . The method of claim 147 , wherein the composition further comprises a catalyst for releasing the therapeutic gas from the therapeutic gas storage form.
154 . The method of claim 147 , wherein the composition further comprises a second different therapeutic gas.
155 . The method of claim 147 , wherein the composition is in the form of a bandage.
