摘要

The tube (1) has a hydrophobic bacterial filter (4) e.g. pipette filter, arranged in an air path of a ventilation lumen (6), and a connection unit (2) formed at the proximate end of a multi-lumen suction tube (13). The connection unit is provided with a suction terminal (10), where a suction lumen (7) of a suction hose is opened in the suction terminal. The filter communicates with an air inlet opening (11) formed in the connection unit, and a closure stopper (3) is provided for closing the air inlet opening.
