Patent ID: 8342178

Claim:
A device for taking and analyzing breathing gas samples, the device comprising: a breathing gas line; a sensor operatively connected to said breathing gas line for recognizing the current phases of breathing; a first gas delivery device; a sample gas loop; a sampling line for sampling from said breathing gas line, wherein said sampling line is connected via said sample gas loop to said first gas delivery device; a sensor system with a second gas delivery device, said sensor system for the analysis of breathing gas samples; a measuring line from said sampling line to said sensor system; a valve in said sampling line for controlling breathing gas sample flow from defined current phases of breathing into said sensor system and into said sample gas loop, said valve comprising an open position and a closed position, said sample loop being in communication with said first gas delivery device, said sensor system with said second delivery device and at least a portion of said measuring line with said valve in said open position and said closed position; and a control unit connected at least to said sensor for recognizing current phases of breathing, to said first gas delivery device and to said valve so that a continuous volume flow of breathing gas samples can be fed to the sensor system from the defined current phases of breathing.
