Device for counting the number of uses of a sensor
First Claim
1. A device for counting the number of usage cycles of a sensor for intracorporeal use, comprising:
- a sensor adapted for intracorporeal use in a subject, said sensor requiring electrical energy for operation thereof;
a counting unit connected to said sensor and containing an identification code unique to said sensor;
extracorporeal equipment to which said sensor is connectable for supplying electrical energy to said sensor;
detection means for detecting each connection of said sensor to said extracorporeal equipment and disconnection of said sensor from said extracorporeal equipment and for generating a detection signal upon each connection and disconnection;
a computer containing stored information identifying previous usage of said sensor; and
sensing means connected to said detection means and to said computer for, upon receipt of said detection signal, determining from said information stored in said main computer whether conditions for a new usage cycle exist and, if so, for incrementing said counting unit by one usage cycle.

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.
