Dressings, systems, and methods for treating a wound on a patient's limb employing liquid control

摘要

Wound dressings, systems, and methods are presented for treating a wound on a patient's limb, such as a venous leg ulcer. The dressings, systems, and methods involve creating airflow within the dressing to vaporize and remove liquid. The airflow may begin when the dressing becomes saturated. The dressings may be used to provide compression and reduced pressure to the wound. Other systems, methods, and dressings are presented herein.

1. A wound dressing for treating a wound on a patient's limb, the wound dressing comprising:
a tubular sleeve member for receiving the patient's limb; wherein the tubular sleeve member comprises:
an elastic compression member formed as a sleeve having a first side and a second, patient-facing side,a fluid-directing member having a first side and a second, patient-facing side, wherein the first side of the fluid-directing member is disposed proximate to the second, patient-facing side of the elastic compression member, and wherein the fluid-directing member is operable to inhibit fluids from flowing through the fluid-directing member, anda pathway member having a first side and a second, patient-facing side, wherein the first side of the pathway member is proximate to the second, patient-facing side of the fluid-directing member, wherein the pathway member is operable to transport a fluid under a pressure gradient; a pressure source fluidly coupled to the pathway member and configured to force a gas into the pathway member; at least one exhaust port fluidly coupled to the pathway member for allowing fluids to exit the wound dressing; and at least one filter fluidly coupled to the at least one exhaust port for removing odors.
