  • Releasable medical drapes
    Patent number: 10912680
    Abstract: A releasable medical drape, and systems and methods having the same, includes at least a liquid-impermeable, vapor-permeable layer, a pressure-sensitive adhesive layer, and a soft-gel layer having a plurality of apertures. The soft-gel layer is configured to be disposed adjacent to a tissue site. A portion of the pressure-sensitive adhesive layer extends through the plurality of apertures in the soft-gel layer to contact the tissue site. The soft-gel layer forms a good seal with the tissue site and the pressure-sensitive adhesive layer extending through the plurality of apertures forms a firm—but releasable—coupling with the tissue site.

  • WOUND THERAPY SYSTEM WITH FLUID CANISTER VOLUME DETECTION
    Publication number: 20200289719
    Abstract: A wound therapy system includes a wound dressing fluidly connected to a fluid canister. The fluid canister is attached to a canister receiving attachment of a housing structure. A pump is fluidly coupled to the canister and is configured to draw a negative pressure within an interior of the canister. A controller of the wound therapy system is configured to operate the pump to apply a vacuum to the interior of the canister and to obtain one or more measurements representative of at least one or a flow rate of air that is exhausted from the canister interior, a pressure within the canister interior and pump ripple. The controller is configured to estimate the volume of the canister based on the comparison of the measured parameters against model data stored by the controller that is representative of the operation of the therapy system with canisters of varying volumes.
