Probe for physiological pressure measurement in the human or animal body and method for monitoring the probe
First Claim
1. Probe for physiological pressure measurement in a human or animal body, comprising a probe head, a line, and a pressure transducer in the probe head, said probe head with said pressure transducer being disposed at a measuring site for measuring pressure, with said probe head being adapted for connection to an analyzer and display unit via said line, characterized in that a counter means is provide which records a number of operational applications of the probe, and characterized in that the counter means has additional means for monitoring and counting overload conditions of the pressure transducer.

Abstract
A probe for physiological pressure measurement in a human or animal body comprises a probe head, a line such as a catheter, and a pressure transducer, particularly an electric transducer, in the probe head. For measuring pressure, the probe head with the pressure transducer is disposed at a measuring site for pressure measurement, with the probe head being adapted for connection to an analyzer and display unit via the line. A counter or controller means is provided for recording a number of operational applications of the probe.
