Abstract

A sensor system serves for measuring, transmitting, processing and representing physiological parameters. The sensor system has least one sensor for measuring at least one physiological parameter. At least one data processing module is in a signal connection with the sensor via a signal cable. A display device serves to represent the sensor data. An expansion module serves to transmit telemetry data. The expansion module may be connected to the data processing module via an interface on the latter. Via a cable-free telemetry line, the expansion module is connected to the at least one sensor or at least one additional sensor for measuring at least one physiological parameter. There results a sensor system in which the patient'"'"'s freedom of movement is enhanced due to the possibility of using telemetry sensors.

Claims
