Tissue monitoring system for intravascular infusion
First Claim
1. A tissue monitoring apparatus comprising:
- a film barrier dressing comprising a flexible membrane integrating one or more sensor elements and an adhesive layer capable of coupling to a patient'"'"'s skin; and
a control unit capable of coupling to the one or more sensor elements in the film barrier dressing, the control unit capable of controlling the sensor elements, sensing one or more parameters indicative of tissue condition in three-dimensional space, and executing a three-dimensional pattern recognition operation on the one or more sensed parameters to determine a tissue condition.

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.
