A wound treatment system for treating a wound on a patient, the wound treatment system comprising: a treatment manifold for disposing proximate to the wound, wherein the treatment manifold has a first side and a second, patient-facing side; a first sealing member for disposing over the first side of the treatment manifold and a portion of intact skin to create a sealed space containing the treatment manifold, wherein the first sealing member comprises a high-moisture-vapor-transfer-rate drape; a reduced-pressure source for producing reduced pressure, wherein the reduced-pressure source is fluidly coupled to the sealed space for delivering reduced pressure thereto; a pressure source; and an evaporative subsystem comprising: an air-movement manifold having a first side and a second, patient-facing side, wherein the second, patient-facing side is disposed proximate to the first side of the first sealing member; a second sealing member disposed over the first side of the air-movement manifold forming a channel space; at least one port formed on the second sealing member for allowing air to exit the channel space; and a Coanda device coupled to the second sealing member and fluidly coupled to the pressure source and to the channel space, wherein the coanda device comprises: an annular nozzle forming a central opening and having an interior passage and a nozzle opening; and a Coanda surface proximate to and downstream from the nozzle opening, whereby fluid exiting the nozzle opening entrains additional fluid from the central opening and produces a combined fluid flow; and wherein the Coanda device is fluidly coupled to a Coanda opening in the second sealing member. a treatment manifold for disposing proximate to the wound, wherein the treatment manifold has a first side and a second, patient-facing side; a first sealing member for disposing over the first side of the treatment manifold and a portion of intact skin to create a sealed space containing the treatment manifold, wherein the first sealing member comprises a high-moisture-vapor-transfer-rate drape; a reduced-pressure source for producing reduced pressure, wherein the reduced-pressure source is fluidly coupled to the sealed space for delivering reduced pressure thereto; a pressure source; and an evaporative subsystem comprising: an air-movement manifold having a first side and a second, patient-facing side, wherein the second, patient-facing side is disposed proximate to the first side of the first sealing member; a second sealing member disposed over the first side of the air-movement manifold forming a channel space; at least one port formed on the second sealing member for allowing air to exit the channel space; and an air-movement manifold having a first side and a second, patient-facing side, wherein the second, patient-facing side is disposed proximate to the first side of the first sealing member; a second sealing member disposed over the first side of the air-movement manifold forming a channel space; at least one port formed on the second sealing member for allowing air to exit the channel space; and a Coanda device coupled to the second sealing member and fluidly coupled to the pressure source and to the channel space, wherein the coanda device comprises: an annular nozzle forming a central opening and having an interior passage and a nozzle opening; and a Coanda surface proximate to and downstream from the nozzle opening, whereby fluid exiting the nozzle opening entrains additional fluid from the central opening and produces a combined fluid flow; and wherein the Coanda device is fluidly coupled to a Coanda opening in the second sealing member. an annular nozzle forming a central opening and having an interior passage and a nozzle opening; and a Coanda surface proximate to and downstream from the nozzle opening, whereby fluid exiting the nozzle opening entrains additional fluid from the central opening and produces a combined fluid flow; and wherein the Coanda device is fluidly coupled to a Coanda opening in the second sealing member.
