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.
