description PROBLEM TO BE SOLVED: To properly measure the average gas partial pressure in outflow blood by simply improving a sampling port.SOLUTION: A gas exchange chamber 3, in which a hollow fiber bundle is housed, is formed in a housing 1, and gas ports 9 and 10 for allowing oxygen-containing gas to flow in and out through the lumens of a hollow fiber membrane, a blood flow channel 4 traversing the hollow fiber bundle in the gas exchange chamber to allow blood to flow, blood inlet and outlet ports 5 and 6 provided so as to be opposed to the central parts of both end parts of the blood flow channel and the sampling port 11 branched from the blood outlet port are provided in the gas exchange chamber 3. The nozzle 20, which is provided to the lumen of the sampling port and of which the leading end is positioned in the blood outlet port, is provided and the inner diameter (d) of the leading end of the nozzle is smaller than the inner diameter F of the blood outlet port at the place where the leading end of the nozzle in the axial direction of the blood outlet port is positioned. A part of blood flowing out of the blood outlet port can be sampled through the nozzle.
