The invention relates to a device for selective ventilation of one or both lungs of a patient, comprising an endotracheal tube to be arranged in the trachea of the patient and having a proximal and a distal end, an endobronchial tube connected thereto and having a proximal and a distal end, the distal end of which extends beyond the distal end of the endotracheal tube, and means for positioning by feel the distal end of the endobronchial tube in at least a longitudinal direction of the trachea. The positioning means are herein adapted to also position the distal end of the endobronchial tube in a peripheral direction of the trachea. The positioning means can be arranged close to the distal end of the endobronchial tube and can extend so far outside the periphery thereof during use that they come to lie on the carina of the patient. The positioning means can also be asymmetrical relative to the periphery of the endotracheal and/or endobronchial tube and can be adapted for co-action with the trachea wall. The positioning means can comprise a balloon or a resiliently deformable member.
A device for selective ventilation of one or both lungs of a patient, comprising:
A method for selective ventilation of one or both lungs of a patient, comprising of arranging in the trachea of the patient an endotracheal tube with a proximal and a distal end and inserting an endobronchial tube with a proximal and a distal end through the endotracheal tube into the trachea, wherein the distal end of the endobronchial tube extends beyond the distal end of the endotracheal tube, and wherein the endobronchial tube is positioned by feel in at least a longitudinal direction of the trachea such that the distal end thereof extends into a bronchus of the patient, wherein the endobronchial tube is positioned by feel in a peripheral direction of the trachea such that the distal end thereof extends into a chosen bronchus of the patient, wherein positioning means are arranged closer to the distal end than to the proximal end of the endobronchial tube which extend outside the periphery thereof during use, wherein the endobronchial tube extends through the positioning means, and the endobronchial tube is inserted so far that the positioning means contact the carina of the patient and wherein the positioning means are arranged asymmetrically about the periphery of the endobronchial tube and are adapted for co-action with a part of the trachea wall between the mouth of the patient and the carina of the patient so as to urge the endobronchial tube out of the centre of the trachea, wherein the endobronchial tube is guided into the chosen bronchus of the patient by rotating the positioning means in the trachea.
