Abstract

The portable sensor device is connected with the arterial pressure measurement catheter by way of a pressure hose. The electronic pressure sensor is accommodated in the sensor housing. The analog sensor signal is output to the patient monitor by way of a cable. Aside from the channel for the analog sensor signal, additional channels are provided for communication between sensor device and patient monitor. A bidirectional channel serves for writing to and querying the memory module, in which patient data, such as age, gender, height/weight, etc., can be stored. The three-way cock possesses the settings “M” (measurement operation) and “0” (calibration measurement), in which the contactor is brought into connection with the contact. The switching contact is transmitted to the patient monitor, which thereby automatically recognizes zeroing of the sensor.
