Abstract: A tubular flexible suction catheter for introduction into the trachea and the bronchial system, has at least one continuous lumen for suctioning fluids out of a lung and a distal end zone that is fashioned to be wavy in an approximately W-shape in the longitudinal extension of the suction catheter.

Abstract: Tubular flexible probe for insertion in the wind-pipe or in the bronchial system, in particular for use as a suction catheter with a tube (10) having an outside diameter of roughly 5-8 mm and a length of roughly 30-50 cm. Its end, which can be inserted in the wind-pipe or in the bronchial system can be designed as an annular collar (12) and in the region of the annular collar may have holes (21) with at least one channel (2) having a diameter of about 1 to a maximum of 2 mm for the conveyance of medicaments. Its inlet (23) is provided with a connection piece (3) for attachment of a syringe.

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.
