Dynamic, reduced-pressure treatment systems and methods

A method of manufacturing a dynamic, reduced-pressure treatment system for treating a tissue site on a patient, the method comprising the steps of:

• providing a manifold for placing adjacent to the tissue site and operable to distribute reduced pressure to the tissue site;
• providing a sealing member for coupling to an epidermis of the patient and operable to cover the manifold and to form a fluid seal between the sealing member and the tissue site;
• providing a reduced-pressure source for developing a reduced pressure;
• providing a reduced-pressure delivery member for delivering reduced pressure from the reduced-pressure source to the manifold, the reduced-pressure delivery member comprising a first lumen and a second lumen;
• segregating the first lumen from the second lumen with a liquid-impermeable-and-gas-permeable member, the liquid-impermeable-and-gas-permeable member adapted to substantially preclude liquid from entering the second lumen to provide a liquid flow in the first lumen and a gas flow in the second lumen;
• and
• coupling a wave generator in fluid communication with the first lumen, the wave generator for imparting a wave to the liquid flow in the first lumen.

A method for treating a tissue site on a patient, the method comprising the steps of:

• disposing a manifold adjacent to the tissue site, wherein the manifold is operable to distribute reduced pressure to the tissue site;
• placing a sealing member on an epidermis of the patient to cover the manifold and to form a fluid seal between the sealing member and the tissue site;
• fluidly coupling a reduced-pressure delivery member to the manifold;
• fluidly coupling the reduced-pressure delivery member to a reduced-pressure source;
• providing reduced pressure to the manifold from the reduced-pressure source;
• substantially segregating liquid and gas carried by the reduced pressure and transmitted through the reduced-pressure delivery member from the tissue site into a separate liquid flow and a separate gas flow in the reduced pressure delivery member;
• and
• coupling a wave generator in fluid communication with the separate liquid flow for imparting a wave to the liquid flow.
