摘要:
Exemplary methods and devices can be provided for an improved wound dressing that facilitates healing. For example, the dressing can include a membrane that maintains a sterile enclosed volume over the wound. Pressure in the enclosed volume can be reduced by deforming the membrane and compressing a resilient open-cell sponge provided therein, facilitating a relatively unobstructed flow of air out of the enclosed volume. Oxygen and/or moisture can be introduced by a controlled flow of moist oxygen-containing gas into the enclosed volume. An oxygen-producing reaction within the enclosed volume using calcium peroxide or the like can also provide oxygen to the wound site. An external vacuum source that includes compressible foam can also be coupled to the enclosed volume to provide a reduced pressure therein. The external vacuum source can be attached to a user's body to maintain the reduced pressure without use of electricity.
