Abstract: A device and method are provided to monitor for early detection of anomalous conditions in a discharge fluid through a catheter tube. A liquid sensor is configured to detect the presence of liquid in the catheter tube. A unique photo-Darlington turbidity sensor may be configured to monitor turbidity of a discharge liquid exiting through the catheter tube. A color sensor may be configured to monitor color of the discharge liquid exiting through the catheter tube. A processing circuit may be coupled to the liquid sensor, photo-Darlington turbidity sensor, and color sensor and configured to determine whether an anomalous condition exists based on readings provided by the liquid sensor, photo-Darlington turbidity sensor, and/or color sensor. A warning device provides an alert if an anomalous condition is detected.
