Abstract

A tubular flexible probe for introduction into the trachea and, respectively, into the bronchial system, has a continuous first lumen with a connecting piece provided at the proximal inlet end for connection to a suction device and, extending therebeside, a further small lumen having a smaller diameter than the first lumen. A wall of the smaller lumen has a recess in the zone of the proximal inlet end of the probe with an elastic connecting hose being inserted with one end in the smaller lumen in the recess. For the alternating introduction of medicaments and, respectively, irrigation solution 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 lenght of about 30-55 cm and an outer diameter of about 5-8 mm. The large first lumen has a diameter of about 3-4.5 mm, the small lumen has a diameter of about 1 to maxially 2 mm, and the two lumens 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. An attachment for a syringe is formed at the inlet end of the connecting hose.
