Gluocose sensing system with auxiliary display

A system for monitoring blood glucose concentration of a patient, the system comprising: a sensing device including: a blood glucose sensor (100) to sense blood glucose data, and sensor electronics (120) in electrical communication with the blood glucose sensor; and a patient monitor (300) adapted to communicate with the sensing device, wherein the sensor electronics are adapted to transmit device information to the patient monitor while the sensor is sensing the blood glucose data and to transmit sensed blood glucose data and wherein the patient monitor is adapted to send requests for device information to the sensor electronics.
