The present invention relates to a wound contact surface for a wound dressing. The wound contact surface can be incorporated into a wound dressing, such as a foam dressing, to provide a non-adherent layer between the dressing and the skin/wound. In aspects, the invention also relates to methods of preparation of the contact surface and dressings comprising same. The wound care surface and dressings comprising same have particular utility in the treatment of burns and blistering conditions such as epidermolysis bullosa.

An electrically-heatable plaster that comprises a self-adhesive skin contact layer, an electrically-conductive textile fabric in which electrically-conductive fibres are in contact with one another, as a heating element, and optionally at least one active substance, as well as to a method for production and the use of same for local heat therapy and/or transdermal application of active substances.

A wound packing material is provided, suitable for use in negative pressure wound therapy, including a body of a porous material, the body including frangible regions defining a plurality of portions, the frangible regions allowing the portions to be selectively removed from the body. Methods of manufacturing the wound packing material, and methods of its use are also provided.

A method of manufacturing a laminated dressing that includes providing a lower layer having a fiber material that directly contacts a patient's skin and a wound area, providing an upper layer that has a foam or foam-like material that absorbs exudate and moisture, and binding the fiber-based lower layer and the foam-based upper layer with a binder layer comprising a binder material, the binder layer including a series of perforations. The perforations in the binder layer are formed by removing material from the binder layer with a pattern coated adhesive sheet prior to binding the fiber-based lower layer and the foam-based upper layer.

A method for manufacturing a steel sheet having a yield strength YS of more than 1000 MPa, a tensile strength TS of more than 1150 MPa and a total elongation E of more than 8%, includes the steps of—preparing a steel sheet through rolling from a steel containing in percent by weight 0.19% to 0.22% C, 2% to 2.6% Mn, 1.45% to 1.55% Si, 0.15% to 0.4% Cr, less than 0.020% P, less than 0.05% S, less than 0.08% N, 0.015% to 0.070% Al, the reminder being Fe and unavoidable impurities; and soaking the sheet at an annealing temperature TA between 860° C. and 890° C. for a time between 100 s and 210 s, cooling the sheet to a quenching temperature QT between 220° C. and 330° C., from a temperature TC not less than 500° C. at a cooling speed not less than 15° C./s, heating the steel sheet during a time between 115 s and 240 s up to a first overaging temperature TOA1 higher than 380° C., then heating the sheet during a time between 300 s and 610 s up to a second overaging temperature TOA2 between 420° and 450° C., cooling the steel sheet to a temperature less than 100° C. at a cooling speed less than 5° C./s. The structure of the steel contains more than 80% of tempered martensite, more than 5% of retained austenite, less than 5% of ferrite, less than 5% of bainite and less than 6% of fresh martensite.

Described is a process for introducing perforations in a laminate that comprises a silicone gel. The process includes the following steps: bringing an array of perforating elements in contact with a deformable layer of a laminate that at least includes a substrate layer, a layer comprising a silicone gel and a deformable layer, wherein said deformable layer covers said layer including the silicone gel; applying ultrasonic energy to said laminate in order to simultaneously introduce a plurality of perforations into said laminate, while providing deformed portions in said deformable layer, wherein said deformed portions penetrate into the plurality of perforations in said laminate; after having introduced said plurality of perforations into said laminate, keeping said deformable layer in contact with said layer including the silicone gel, such that said deformed portions remain penetrating into said plurality of perforations, for at least 12 hours.

A wound dressing comprising a breathable film, a fluid-absorption layer and a fluid-wicking layer, use of the wound dressing for treating or preventing wounds and/or for securement of a device that has been at least partially inserted in the skin, and methods of making said wound dressings.

Described herein are adhesive support devices, which may include adhesive medical devices. In particular, three-dimensional adhesive medical devices from a single layer of material, typically by stamping or pressing (including cold pressing) a sheet of the material to form rigid and complex 3D shapes capable of use for a variety of medical and non-medical purposes. These adhesive support devices typically also include an adhesive material allowing the device to be attached to a subject's skin and/or mounted on a surface (e.g., wall, etc.). In particular, described herein are methods of manufacturing, assembling, and using adhesive support devices.

Provided is an adhesive sheet for affixation to the body which is excellent in enhancement and persistence of the blood circulation promoting action, has high affixability and conformability as a sheet, and is easily and widely applicable to the body in any use situation. That is, the present invention relates to an adhesive sheet for affixation to the body housed in a container, containing the following components (A) and (B): (A) bubbles containing carbon dioxide gas in a bubble fraction of 10% or more and 40% or less, and (B) water, wherein the total area occupied by bubbles having an imaginary diameter of 5 mm or more is 10% or less, in 100% of the surface area of the adhesive sheet for affixation to the body, a content of carbon dioxide gas in the total amount of the adhesive sheet for affixation to the body is from 100 to 20,000 ppm, and the adhesive sheet for affixation to the body is sealed in a low gas-permeable container.

Devices, kits and methods described herein may include a dressing that is pre-strained and stored for a period of time after which the dressing is applied to the skin of a subject.
