Abstract:
1. A system for monitoring the pressure in a blood line comprising: a bloodline; a pressure transducer line branching off the blood line and leading to a pressure transducer for measuring the pressure in the pressure transducer line; a first pressure transducer protector filter in the pressure transducer line dividing the pressure transducer line into a blood line section between the blood line and the first filter, and a pressure transducer section between the first filter and the pressure transducer, the first pressure transducer protector filter being permeable by a gas but not by a liquid, a first sensor configured to detect the presence of a first liquid in the pressure transducer section of the pressure transducer line; and a second sensor configured to detect the presence of a second liquid in the pressure transducer section of the pressure transducer line, said second liquid being different than said first liquid and said second sensor for detecting said second liquid being of a different type or configured differently than said first sensor.
