Claim 1:
2. The integrity detection system according to claim 1, further comprising a further ultrasound transducer,
wherein the further ultrasound transducer is configured to emit a second ultrasound test signal in the wall of the vessel along a first path to the first ultrasound receiver and along a second path to the further ultrasound transducer,
wherein the first ultrasound receiver and the further ultrasound transducer are further configured to receive the second ultrasound test signal and to transmit the received second ultrasound test signal to the signal processing unit, and
wherein the signal processing unit is further configured to detect a second time of flight of the received second ultrasound test signal and to determine that the acoustic coupling of the first ultrasound transducer and the further ultrasound transducer is intact if the detected second time of flight corresponds to corresponding lengths of the first and the second paths of the received second ultrasound test signal.
