A method for manufacturing a wound dressing having a substrate, and a wound dressing manufactured by such a method are described. The method has a step of providing a sacrificial layer of material to be perforated by means of a hot pin perforator, in order to remove any molten residues on the heated pins of the hot pin perforator, before the same pins are used to make holes in the substrate. The presented method is cost effective, robust and reduces the risk of contaminating substances being embedded in the substrate during the hole making process.

Provided are buffered adhesive compositions comprising a high molecular weight non-neutralized polymeric acid and a high molecular weight partially neutralized polymeric acid and products such as wound dressings and ostomy skin barriers incorporating the compositions.

A disposable dressing forms a compartment around and above a wound site and a volatile antimicrobial compound is allowed to sublimate/evaporate into the compartment. A heating element is included in the dressing, with heat stimulating wound healing and simultaneously accelerating sublimation/evaporation of the antimicrobial compound.

A tissue bonding article includes a flexible material, an adhesive substance applied over at least a portion of a bottom side of the flexible material, and a polymerizable adhesive composition permeated throughout at least a portion of the flexible material.

Provided are buffered adhesive compositions comprising a high molecular weight non-neutralized polymeric acid and a high molecular weight partially neutralized polymeric acid and products such as wound dressings and ostomy skin barriers incorporating the compositions.

The present disclosure provides, inter-alia, an apparatus for wound-dressing. In particular, embodiments of the disclosure provide a wound-dressing apparatus comprising a wrapping element and a pad element, wherein the pad element is foldable and comprises at least one removable portion.

Wound dressings having a delivery system are provided.

Herein is disclosed a composition for application to a wound comprising: a first layer comprising a skin adhesive, wherein the first layer has a wound-facing side and a non-wound-facing side and, in a first area, apertures extend through the first layer from the wound-facing side to the non-wound-facing side; and a second layer disposed on a non-wound-facing side of the first layer, the second layer comprising a polymeric film that is continuous in that it extends over and covers each of the apertures of the first layer, the second layer having a moisture vapour transmission rate (MVTR) of at least 500 g/m.sup.2/24 hours, measured in accordance with BS EN 13726-2:2002, wherein the composition further comprises a third layer disposed between the first layer and second layer, the third layer being a supporting layer for the first layer, the third layer having apertures therethrough, substantially corresponding to the apertures in the first layer. A method of making such a composition is also disclosed.

Tapes and methods including an unbacked construction of at least one liquid layer adhesive that has been at least one of dried and cured. Occlusive tissue dressings, tapes and methods including an elastomeric drape and, for backed drapes and some unbacked drapes, a liquid component, at least partially cross-linked at least after one of drying and curing, suitable for application at a dressing-to-skin interface in order to create a substantially air-tight seal. The same or a different liquid component may be applied by a user at a tube-to-dressing interface of an elastomeric drape to create a similar air-tight seal around the tube, if not occlusively sealed during its manufacture. Featured are unbacked tapes, a drape with liquid sealant component, a liquid layered drape with liquid sealant component, and a liquid layered drape.

Provided are buffered adhesive compositions comprising a high molecular weight non-neutralized polymeric acid and a high molecular weight partially neutralized polymeric acid and products such as wound dressings and ostomy skin barriers incorporating the compositions.
