Dressing for negative pressure therapies formed by a multilayer structure that comprises a first layer (1) and a second layer (2), joined together by their respective perimeter edges, in which the first layer (1) is formed for a laminar body that presents: - a first internal face (3), intended to face inward and face the second layer (2), - a first external face (4), intended to be oriented externally, - a plurality of first through holes (5) that allow the passage of fluid, the dressing being characterized in that the second layer (2) comprises: - two laminar bodies (6) jointly connected to each other, each of which comprises a plurality of second through holes (8) that allow the passage of fluid, and - a plurality of tubular elements (7) arranged between the sheet bodies (6), and inside which a gaseous fluid under pressure is housed and maintained, in which the first layer (1) and the second layer (2) overlap mutually so that the first (5) and second through holes (8) face each other, creating channels that allow the passage of negative pressure between two opposite faces of the dressing.
