Abstract: This disclosure includes wound dressings and systems for effluent management of topical wound therapy and related methods. Some devices, which are configured to dilute therapeutic gas effluent flowing from a dressing, comprise a therapeutic gas source configured to provide therapeutic gas to the dressing; a container comprising a sidewall that defines a chamber configured to receive therapeutic gas effluent from the dressing; a negative pressure source configured to be coupled to the container such that the negative pressure source can be activated to draw fluid from the dressing through the chamber of the container; and a diluent gas source configured to deliver a diluent gas to dilute therapeutic gas effluent before the therapeutic gas effluent enters the negative pressure source.

Abstract: Provided herein is a system and method for coupling a wearable therapy system to a dressing and detaching the wearable therapy system from the dressing. One aspect provides a system including a drape with a switchable adhesive layer and a therapy system adhered to the drape via the switchable adhesive layer. The therapy system includes one or more radiation sources that can emit radiation wavelengths (e.g., light or electromagnetic waves) to impinge upon the adhesive and deactivate the adhesive when it is desired to remove the therapy system from the drape.

Abstract: This disclosure includes negative pressure wound therapy dressings with local oxygen generation for topical wound therapy. The dressings (18) for facilitating delivery of oxygen and application of negative pressure to target tissue include a manifold (46) that defines a plurality of gas passageways (50) and is configured to allow communication of oxygen to the target tissue; an oxygen-generating material (146) that is configured to release oxygen when exposed to water; a gas-occlusive layer (74) configured to be disposed over the manifold and the oxygen-generating material and coupled to tissue surrounding the target tissue such that an interior volume containing the manifold and the oxygen-generating material is defined between the gas-occlusive layer and the target tissue; and a port (94) coupled to the gas-occlusive layer and configured to be coupled to a negative pressure source.
