Abstract
Thermoresponsive skin barrier assemblies are disclosed. One such wound treatment assembly includes a pump configured to expel a biosealant to a pump output port when subjected to a thermal stimulus, and an adhesive substrate layer for covering the wound. The adhesive substrate layer includes a conduit configured to transport the biosealant from the output port to the wound. The assembly further includes a control module in signal communication with a wound leakage sensor configured to activate a heating element disposed in proximity to the pump when wound leakage is detected.
Claims17
An ostomy apparatus, comprising:
- a substrate configured to adhere to a user's skin;
- an electrode array including a first electrode pair and a second electrode pair arranged on the substrate;
- and
- a control module coupled to the electrode array, the control module configured to determine:
- a first change in impedance of the first electrode pair to determine a first propagation direction of moisture absorbed by the substrate;
- and
- a second change in impedance of the second electrode pair to determine a second propagation direction of moisture absorbed by the substrate.
