Abstract: Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing may include a cover layer, an activator layer such as an acid providing layer and nitric oxide source layer, such as a nitrite providing layer. The activator layer may include acidic groups and may be hydrogel, xerogel, or other suitable material. The nitric oxide source layer may include a nitrite salt. Nitrite ions of the nitric oxide source layer may react with the acidic groups of the activating layer to generate nitric oxide. The wound dressing may further include a composite layer, such as a layer with an acquisition distribution layer embedded within an activator gel layer. Additional composite layers may include various absorbent materials embedded within an activator gel layer.

Abstract: Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing may include a cover layer, a nitric oxide source layer, such as a nitrite providing layer, an absorbent layer such as a foam, and a gel material adhered to the absorbent layer. The gel material may include perforations in a cured pattern structure. The perforations may define a plurality of fluid channels extending through the gel material. The gel material may form an active wound contact layer for use in generating nitric oxide.

Abstract: An ostomy pouch includes a front wall, a rear wall and an inlet for receiving human waste. The pouch has a comfort layer provided at least on the front wall. The comfort layer on the front wall has a colour with a value in the range L*=56.0 to 59.0, a*=+2.0 to +5.0 and b*=0.0 to +3.0 measured in the CIE L*a*b* colour code system.

Abstract: A monitoring and/or therapy apparatus can include a contact layer having a stretchable or substantially stretchable substrate, at least one strain sensor coupled with the contact layer, and electronic circuitry electronically coupled with the at least one strain sensor configured to determine an amount of an elongation of the at least one strain sensor based on a change in a resistance or capacitance of the at least one strain sensor. The at least one strain sensor can include a plurality of stretchable tracks positioned on the substrate, and can be configured such that the resistance of the at least one strain sensor increases as the contact layer is elongated and/ or curved. In some arrangements, the apparatus and/or the substrate can be attached to or adjacent to a user’s joint, and/or a wound, and can be configured to have reduced pressure applied to the space under the contact layer..
