ABSTRACT:
A device for counting the number of usage cycles of a sensor, for intracorporeal electrophysiological measurement and/or therapy, has a counting unit, connected to the sensor, containing a specific identification code for the sensor, and a detection unit which detects the sensor's connection/disconnection to/from external measurement and therapy equipment. The detection unit causes a sensing unit to read a sensor identification code in the counting unit whenever the sensor is connected so as to determine, from information about sensor usage stored in a main computer, whether conditions for a new usage cycle have been met and, if so, increments the counter's contents by one usage cycle.
