Abstract: An assembly used to promote wound healing through the creation of an oxygen gradient, whereby the oxygen gradient hastens the diffusion of oxygen from underlying capillaries and subcutaneous tissue up through and over an overlying target site of skin tissue. In an exemplary embodiment, the assembly provides a flush cycle and/or a negative pressure cycle to enhance the flow of oxygen from the subcutaneous tissue and the capillaries to the target site. In an exemplary embodiment, the assembly further comprises a means for maintaining a constant relative humidity over the wound site.

Abstract: A tissue oxygenation device for creating and oxygen gradient that promotes the diffusion of oxygen from underlying capillaries and subcutaneous tissue up through and over an overlying target site of skin tissue, comprising: a gas impermeable encasement which forms a chamber which surrounds the target site when the encasement is positioned over the target site; an oxygen scavenging member comprising an oxygen scavenger, wherein the oxygen scavenging member is contained within the chamber such that the oxygen scavenger is exposed to oxygen within the chamber, and further wherein the oxygen scavenger removes oxygen contained within the chamber at a continuous rate; and an adjustable cuff, wherein the adjustable cuff comprises a pliable body which is attached to the gas impermeable encasement on an end of the body and to the target site at another end of the body; wherein the gas impermeable encasement and the adjustable cuff jointly operate to seal the target site within the chamber.

Abstract: Based on diffusion principles and Fick's Law of difflision, Applicant has developed a method and two apparatuses to increase tissue oxygenation through a patient's damaged tissue to heal wounds quickly. Applicant's method is to create an enclosed environment, immediately outside a patient's damaged tissue, in which the oxygen concentration is reduced to prompt an outward supply of oxygen flows from blood capillaries to the damaged tissue and eventually out of the skin. Applicants' disclosed apparatuses use two different ways to reduce the oxygen: oxygen scavengers (e.g., oxygen-absorbing packets); and burning off the oxygen.
