Abstract

PURPOSE: To make it possible to feed a fluid without exerting an undesirable influence on the measurement of a cardiac output by dividing the 1st and the 3rd lumens with the 1st partition, dividing the 2nd and 3rd lumens with the 2nd partition and positioning a temp. sensitive element on rather a base end side than an opening part.
CONSTITUTION: The inner cavity of a catheter main body 21 is divided into four parts with three partitions 21, 22 and 23 and a thermister lumen 24 is formed with the inner wall 20 of the inner cavity and the 1st partition 21. Thermisters 41 and 45 are positioned water-tightly in side holes 281 and 285 and a regurgitation hole 7 is positioned on rather a base end side than the thermisters 41 and 45. On the other hand, the 2nd partition 22 is formed on the facing position in the inner cavity and a lumen 26 for measurement of pressure is formed with it and the inner wall 20 of the inner cavity. In addition, the 3rd partition 23 is provided in a space constituted of the inner wall 20 and the partitions 21 and 22 to form a balloon lumen 27, and a lumen 25 for feeding an indicator liq. is formed between the partitions 21 and 22.
