ABSTRACT OF THE DISCLOSURE: A tubular flexible probe for introduction into the trachea or bronchial system, contains a continuous lumen with a connecting piece provided at the proximal inlet end for connection to a suction device. Beside this first lumen, there is a further lumen having a smaller diameter than the first lumen, wherein the wall of the smaller lumen has a recess in the zone of the proximal inlet end of the probe. One end of an elastic connecting hose is inserted in the smaller lumen in this recess. The probe allows for the alternating introduction of medicaments and irrigation solutions at a high exit velocity at the distal probe end through the smaller lumen and for removing secretions or the like by suction. The probe has a length of about 30-55 cm and an outer diameter of about 5-8 mm, the large lumen has a diameter of about 3 - 4.5 mm, the small lumen has a diameter of about 1 to maximally 2 mm, and the two lumina extend from the proximal end up to the distal, rounded end of the probe in side-by-side relationship and in parallel to the probe axis, and there is an attachment for a syringe at the inlet end of the connecting hose.
