a tracheal tube connectable to a mechanical ventilator, the tracheal tube having a main lumen for delivering a breathing gas from said mechanical ventilator into a lung of the patient; a cuff, mounted at a distal end of the tracheal tube, to be located in the subglottal region of the patient; a cuff inflation lumen for inflating said cuff, to form in the subglottal region a continuous volume which extends, within the subglottal region, from said cuff to the vocal cords of said patient; and at least three additional lumens, other than said main lumen and said cuff inflation lumen; and
a controller configured for performing, via said at least three additional lumens:
a delivery of liquid to said continuous volume, a suctioning of liquid from said continuous volume, and a venting said continuous volume;
wherein each of said at least three additional lumens ends with a port at said continuous volume and outside any cuff of said tracheal tube;
wherein said delivering said liquid is via a rinsing port at said continuous volume, said suctioning of said liquid is via a suctioning port at said continuous volume, and said venting is via a venting port at said continuous volume, wherein said rinsing port, said suctioning port, and said venting port are separated from each other, and wherein lumens that end with said rinsing port, said suctioning port, and said venting port are separated from each other.
