Multilumen tracheal catheter to prevent cross contamination

摘要

A multilumen tracheal tube (12) or catheter is disclosed. The tube (12) has a plurality of ingress (44) and egress (45) lumens, each having a suction (40) or discharge (41) port as appropriate. At least one rotatable collar (38) is provided. The collar (38) is capable of selecting various combinations of suction (40) and discharge (41) ports without increasing the likelihood of cross contaminating any others .
