A dressing for an open wound includes a cover layer dimensioned for positioning relative to a wound bed. The cover layer permits an evacuation of the space around the wound bed such that a sub-atmospheric pressure may be established to stimulate healing and facilitate the removal of fluid from the wound. Multiple performance zones in the cover layer allow the wound dressing to remain in position through repeated cycles of evacuation without placing undue strain on the wound bed. An outer peripheral zone may include a high peal-strength adhesive while an intermediate zone may include a shear resistant adhesive. A central zone may be devoid of any coating to maximize moisture transmission through cover layer.

The securement device eliminates the drawbacks of prior venous cannulas securement method by providing various plates, substrates and adhesive layers in the securement device which secures the article firmly onto the underlying substrate arresting movement in all axis that does not need any additional form of securement.

Medical tape suitable to be adhered onto a skin wound for healing of the skin wound or onto a scar for suppressing a thickening, an expansion and an extension of the scar after healing of the wound. The medical tape includes a flexible and stretchable substrate consisting of a plastic film or foil; a release paper which is adhered to one side of the substrate via a pressure-sensitive adhesive layer; and a peelable support consisting of two sheets of plastic films which are adhered to another side of the substrate via a silicone-coating layer and a slightly adhesive layer, in that order. The two sheets of plastic films are butted with each other at the midpoint of a longitudinal direction of the substrate, and over a widthwise direction of the substrate. The medical tape advantageously applies a shrinking force only to a wound surface or a scar surface.

Methods and compositions for securing to and removing adhesive tapes from substrates, e.g., delicate substrates such as skin, are described. The methods include providing an adhesive tape comprising an adhesive layer and a support layer in contact with the adhesive layer. A first adhesion level between the adhesive layer and the support layer is, or can be controlled to be, less than a second adhesion level between the adhesive layer and the substrate. The methods further include applying the adhesive tape to the substrate by contacting the adhesive layer to the substrate while the support layer remains in contact with the adhesive layer; and removing the support layer from the substrate by separating the support layer from the adhesive layer.
