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.
Claims7
A skin barrier appliance, comprising:
- a substrate comprising top and bottom surfaces and a central aperture, said substrate being disposed between upper and lower hydrocolloid layers;
- a first moisture sensor disposed on said top surface of said substrate;
- and
- a second moisture sensor disposed on said bottom surface of said substrate;
- wherein each of said first and said second moisture sensors are configured to detect effluent and send an activation signal to a pump containing a flowable substance upon the detection of said effluent;
- and
- wherein said first moisture sensor is configured to detect effluent flow in a radial direction from said central aperture, parallel to said top surface of said substrate, and said second moisture sensor is configured to detect effluent flow orthogonal to said bottom surface of said substrate.
A skin barrier appliance, comprising:
- a moisture sensor disposed between upper and lower hydrocolloid layers configured to detect moisture and send an activation signal to a pump containing a flowable substance upon the detection of said moisture;
- and
- an expandable fluid delivery channel formed from at least two overlapping sheets of a polymeric material;
- wherein said moisture sensor is configured to detect moisture flow in either of two substantially orthogonal moisture flow directions.
