ABSTRACT:
An infusion system has a capability to monitor infusion complications such as extravasation, tissue necrosis, infiltration, phlebitis, and blood clots. The infusion system has at least partially transparent flexible film barrier dressing in a flexible membrane that incorporates a plurality of sensors capable of detecting tissue condition and a control unit capable of coupling to the film barrier dressing that monitors signals from the sensors. A device is capable of executing non-invasive physiological measurements to characterize physiologic information from cross-sectional surface and subcutaneous tissue to detect the presence or absence of tissue conditions such as infiltration or extravasation during intravascular infusion. In some examples, the device utilizes depth-selective methods to sense, detect, quantify, monitor, and generate an alert notification of tissue parameters.
