Publication number: 20140114132Abstract: A device for supporting a tracheal tube during tracheal intubation. The device is applied to the blade of a laryngoscope, or similar instrument. It includes one or more planar elements, each element having a profile adapted to the curvature of the blade a the location in which it is placed. On command, each element protrudes out from the blade through a longitudinal groove, in order to create one or more fixed transversal walls. Once the walls are created, the tracheal tube is then inserted into the laryngoscope and its far end is moved across the walls, and towards the trachea of the patient. The device also includes a set of mechanical gears that are controlled by a sliding button such that moving the button from a back position to a front position moves each of the planar elements from the position within the blade to the protruding position.Type: ApplicationFiled: June 12, 2012Publication date: April 24, 2014Inventor: Andrea De Domenico
