Smart connector for a medical device

A sensor assembly that is configured to measure characteristics of a fluid entering or exiting a patient via a catheter, comprising:

• a flow tube that is configured for coupling to a dialysis machine and to accept the fluid at a first end of the flow tube and expel the fluid at a second end of the flow tube;
• a tube-shaped docking station having a plurality of sensors disposed therein, the plurality of sensors including at least one IR temperature sensor that is external from a housing of the dialysis machine and configured to measure temperature of the fluid, at least one contact temperature sensor that is configured to measure temperature of the fluid, at least one clarity sensor that is configured to measure cloudiness of fluid from the patient, and at least one pressure sensor that is external from the housing of the dialysis machine and configured to measure pressure of the fluid, wherein information from the contact temperature sensor is combined with information from the IR temperature sensor to provide temperature measurement of fluid in the flow tube and wherein sensor information from the IR temperature sensor is given less weight when combined with information from the contact temperature sensor if information from the clarity sensor indicates that the fluid is cloudy;
• and
• a tube-shaped connector that is configured to be coupled to the docking station and is connected to the flow tube, wherein the docking station is provided in two parts that swing together on a hinge to close around the connector to couple the docking station to the connector.
