Abstract:
1. A bandage for application to the skin of an animal to promote skin health, skin healing and tissue healing, the bandage comprising a reservoir containing perfluorochemical fluid, the reservoir having a top and a bottom, the top of the reservoir being sealed to the environment, the reservoir being sealed on the bottom by a gas-permeable membrane, the gas-permeable membrane being sealed to the environment with a releasable cover, the perfluorochemical fluid having at least one gaseous material dissolved therein, the at least one gaseous material comprising both oxygen and carbon dioxide, the perfluorochemical fluid containing less than a predetermined amount of carbon dioxide dissolved in the perfluorochemical fluid, the predetermined amount of carbon dioxide having a partial pressure of 0.1 mm Hg, the concentration of oxygen and carbon dioxide in the perfluorochemical fluid being selected so that when the bandage is applied to the skin, oxygen will diffuse across the membrane from the reservoir to the skin and carbon dioxide will diffuse across the membrane from the skin to the reservoir.
