Dynamic gas-flow wound dressing assembly and method for enhancing the effect of generated gas flow across a wound

A dynamic gas-flow wound dressing assembly comprising:

• a medical dressing covering having an upper surface, a lower surface opposing the upper surface;
• a gas flow framing structure coupled to the medical dressing covering, with an outer surface and an inner surface opposing the outer surface of the gas-flow framing structure, and defining a gas inlet, a gas flow channel within the gas-flow framing structure, and a plurality of enclosed gas outlets disposed on the inner surface of the gas-flow framing structure and downstream of the gas inlet, the plurality of enclosed gas outlets each operably configured and oriented to direct a generated gas flow comprising air at about atmospheric pressure therethrough, and to a framing area defined by the inner surface of the gas-flow framing structure and disposed proximal to the lower surface of the medical dressing covering;
• and
• a scaffolding partition member of a flexible material, with a lower surface without any adhesive disposed thereon, with an outer surface, an inner surface opposing the outer surface of the scaffolding partition member, with an upper surface opposing the lower surface of the scaffolding partition member and having an adhesive material disposed thereon, with an edge having a height, the edge creating separation between the gas flow framing structure and a wound area on the skin, and defining an enclosed scaffolding treatment area and scaffolding treatment volume with the inner surface of the scaffolding partition member, the upper surface of the scaffolding partition member selectively removably directly coupled to the gas-flow framing structure in a contouring configuration therewith,
• the scaffolding partition member further having a plurality of intake ports aligned with the plurality of enclosed gas outlets, a plurality of outlet ports, and at least one gas transportation channel internally disposed within the scaffolding partition member and fluidly coupled to the plurality of intake ports and the plurality of outlet ports.

A method for enhancing the effect of generated gas flow across a wound, comprising:

• identifying a wound area on the skin;
• coupling a gas flow framing structure to a medical dressing covering, the gas flow framing structure defining a gas inlet, a gas flow channel within the gas-flow framing structure, and a plurality of enclosed gas outlets operably configured and oriented to direct a generated gas flow therethrough;
• deforming a resilient scaffolding partition member to fit the contours of the skin near the wound, the scaffolding partition member having an edge defined by a height, the edge creating separation between the gas flow framing structure and the wound area by applying forces to the skin and directing the gas flow, the scaffolding partition member further comprising a plurality of intake ports, a plurality of outlet ports, and at least one gas transportation channel internally disposed within the scaffolding partition member and fluidly coupled to the plurality of intake ports and the plurality of outlet ports;
• aligning the plurality of enclosed gas outlets of the gas-flow framing structure with the plurality of intake ports of the scaffolding partition member;
• engaging the gas flow framing structure with the scaffolding partition member, whereby the edge of the scaffolding partition member creates separation between the medical dressing and the wound, whereby the scaffolding partition member being directly coupled to the gas-flow framing structure in a contouring configuration therewith;
• introducing the generated gas flow into the gas inlet of the gas-flow framing structure, the generated gas flow being vented at the atmospheric pressure;
• and
• directing the gas from the gas flow framing structure or discharging the gas through the at least one gas transportation channel and the plurality of outlet ports of the scaffolding partition member, whereby the scaffolding partition member increases the treatment volume over the wound.
