  • Publication number: 20240024561
    Abstract: Systems and methods for treating a plurality of tissue sites include a multi-port therapy unit. The multi-port therapy unit includes a plurality of patient-side ports each fluidly coupled to a plurality of conduits and a fluid reservoir fluidly coupled to the plurality of ports. A plurality of pressure sensors are associated with the plurality of patient-side ports to determining a pressure associated with each conduit. A controller is operatively coupled to the plurality of pressure sensors to receive treatment pressure data, monitor pressure for each pressure sensor of the plurality of pressure sensors, and signal an alarm condition if the pressure is outside of a pre-selected range. The system includes a reduced-pressure source fluidly coupled to a dressing at each tissue site through the multi-port therapy unit.

  • Patent number: 11877912
    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.

  • Patent number: 11576818
    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.

  • Publication number: 20210402078
    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.

  • Publication number: 20200197227
    Abstract: Described herein is a wound dressing comprising: a composite island configured to collectively exhibit substantially elastic recovery under wound treatment conditions and comprising a foam layer and an absorbent layer coupled to the foam layer, the foam layer exhibiting substantially elastic recovery under wound treatment conditions and the absorbent layer not exhibiting substantially elastic recovery under wound treatment conditions; a backing layer having a margin that extends beyond the composite island; and an adherent layer disposed on at least the margin of the backing layer. In addition, described herein is a method of eliminating, minimizing, or reducing edema for a wound surrounded by tissue, by positioning the wound dressing over the wound, optionally such that at least a portion of the adherent layer contacts the tissue.
