ABSTRACT:
A triple lumen catheter comprises a transfusion lumen (4), a blood feeding lumen (2) and a blood removing lumen (3). The transfusion lumen (4) has a distal end and a leading end portion (12, 12A), the leading end portion progressively reducing in diameter to a proximal end. A transfusion port (4a) is formed in the proximal end of the transfusion lumen. The blood feeding lumen (2) has a blood feeding port (2a) in a region of the proximal end of the leading end portion, the blood feeding port opening at least partially in an axial direction of the leading end portion. The blood removing lumen (3) includes a pair of blood removing ports (3a, 3b) provided in opposite side walls of the catheter, the blood removing lumen extending from a distal end at least to the blood removing ports.
