DEVICES AND METHODS FOR AIRWAY SUCTIONING

摘要

Described here are devices, systems, and methods for positioning a suction catheter in the airway of a patient. The systems may comprise a suction catheter, a delivery device, and/or a stylet. The delivery device may comprise an elongate shaft, an atraumatic distal end, an elongate passageway, and a retention element configured to releasably couple to an endotracheal tube. The suction catheter may be positioned in the elongate passageway, and the delivery device may help advance the suction catheter into the airway of a patient. In some variations, the delivery device may comprise elements configured to release the suction catheter in the airway after positioning.

1. A method of positioning a suction catheter in an airway of a patient intubated with an endotracheal tube, comprising:
advancing a delivery device into the airway, wherein the delivery device comprises an elongate shaft comprising a central shaft region and an atraumatic distal end; an elongate lumen configured to receive a suction catheter; a proximal alignment region; and a retention element configured to releasably couple to an endotracheal tube; aligning the proximal alignment region of the delivery device with an anatomical landmark to position a distal outlet of the elongate lumen of the delivery device about the vocal cords; and advancing a distal portion of a suction catheter out of the distal outlet of the elongate lumen to advance the distal portion of the suction catheter into an airway.
