The tube drive device farìngeo to assist tracheal intubation.

摘要

b the tube guide device to assist tracheal intubation with pharyngeal d , manufactured in plastic material.Understood by a connection pattern 3 for adjusting the apparatus of ventilatory assistance, a balconete intermediary 1, a distal cuff 2, in addition to balloons and tubes pilots.The cuff 1 is intermediate in base 9 and in the lateral processes, 7, 8, a mold of the laryngo pharynx (Fig. 7).During the introduction of the guide tube in the patient's mouth, he is rotated on its axis in a counterclockwise direction and has its intermediate cuff inflated.The counterclockwise rotation of the guide tube allows its proximal end 11 is positioned to the left side of the mouth of the patient.Leaving the right hand free for the employment of laryngoscope and the introduction of a second tube 19.The cuff inflated with intermediate when the appropriate volume, has a diameter larger than the laryngo pharynx of and attached to the end of this structure anotu00f3mica.When the cuff fits in the laryngo pharynx (Fig. 2), its base is aligned with the back wall of the larynx 15.A tracheal tube passing over the guide tube to slide down the slope 10 progresses to the larynx and trachea.This operation can facilitate tracheal intubation, alleviate some limitations on the use of laryngoscope.Or even make it possible to tracheal intubation when the use of the laryngoscope is insufficient for its realization.With the cuff intermediary empty, the guide tube may be used as a tracheal tube.
