Wound dressing

A wound dressing comprising a wound-covering layer suitable for extending over a wound of a patient, the wound-covering layer having a wound-facing surface and a non-wound facing surface, wherein the wound-facing surface comprises at least one supporting structure for connecting the wound-covering layer to the skin of the patient in use, such that in use the wound dressing can transition from an open configuration in which the wound and an area external to the wound dressing are in fluid communication via at least one opening configured to be between a perimeter of the wound-covering layer and skin of the patient and around the at least one supporting structure, wherein the wound dressing forms a non-linear fluid path between the aperture and the external area, and a closed configuration in which the wound-covering layer has collapsed around the at least one supporting structure and forms a seal over the wound.

A method of manufacturing a wound dressing, comprising connecting a base layer having a lower surface configured for facing the wound and an upper surface configured for facing away from the wound, and an aperture therethrough for locating over the wound, a top layer extending over the aperture and at least a part of the upper surface, and at least one supporting structure located between the top layer and the base layer, connecting the top layer to the base layer, such that the wound dressing can transition from an open configuration in which the aperture and an area external to the wound dressing are in fluid communication via at least one opening at a perimeter between the base layer and the top layer and around the at least one supporting structure, wherein the wound dressing forms a non-linear fluid path between the aperture and the external area, to a closed configuration in which the top layer has collapsed around the at least one supporting structure and forms a seal over the aperture.
