Apparatus and method for selective ventilation of a patient

摘要

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.

1. 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 slidably received in the endotracheal tube 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, wherein the positioning means are adapted to also position the distal end of the endobronchial tube in a peripheral direction of the trachea, and the endobronchial tube extends through the positioning means, wherein the positioning means are arranged closer to the distal end than to the proximal end of the endobronchial tube and extend so far outside the periphery thereof during use that they come to lie on the carina of the patient, and wherein the positioning means are asymmetrical about the periphery of the endotracheal and/or 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.
