At present, the front end of the endotracheal tube at home and abroad extensively adopted in clinical anesthesia is inclined-plane, and inclined-plane, front end, in order to adapt to glottis " 1 " font crack, makes conduit more easily by glottis.Because the inclined-plane of endotracheal tube front end is larger, being often hampered by glottis, epiglottis and larynx than being easier to, making difficult intubation.Violence intubate is repeatedly easy to make inclined-plane damage throat, causes laryngeal edema, dysventilation until patient suffocates.The most common cause of patient death when this is tracheal intubation difficulty.When difficult tracheal intubation, no matter be use fiberoptic intubation or use intubation bougie auxiliary intubation, after branchofiberoscope or bougie are successfully inserted trachea, the situation often occurred send pipe difficulty.Reason is when the front portion of branchofiberoscope or bougie and endotracheal tube intussusceptum point angulation, the inclined-plane of endotracheal tube front end runs into Pyriform sinus, epiglottis or vocal cords etc., very easily be obstructed, send pipe to cause the damage, branchofiberoscope damage, difficult intubation etc. of vocal cords, epiglottis and larynx by force reluctantly.Usual clinically is both at home and abroad that conduit is moulding with leading core, and it is thinner that these lead core, do not exceed the front end of conduit.Often difficult intubation is there is, repeated multiple times intubate in this method use procedure, large to the upper respiratory tract damage of patient.The auxiliary intubation that abroad someone designs leads core for carefully cylindric, first injects trachea leading core during tracheal intubation, more seriously leads core and insert snorkel conduit.When this method inserts snorkel conduit, endotracheal tube is often hampered by vocal cords etc., causes difficult intubation and major injury.Reason is that the internal diameter of the diameter and endotracheal tube of leading core differs greatly, and the inclined-plane of catheter proximal end is often subject to the stop of vocal cords.
For this reason, what we designed a kind of assisted gas cannula leads core, and its front end is a hemisphere, and diameter is 1.5-5mm; Be front cylinder subsequently, long is 0-50mm, and diameter equals the diameter of front end hemisphere; Be a round platform subsequently, the diameter of starting section equals the diameter of front cylinder, and the diameter in rear cross section equals the diameter of rear cylinder, and length is 0-50mm; Be rear cylinder subsequently, diameter is 1.5-10mm, and length is 45-75cm, is finally rear quarter, and diameter equals the diameter of rear cylinder, and on rear cylinder, hemisphere 15-22cm place in distance front end establishes a front tooth labelling.First according to the thickness of patient's trachea, select the endotracheal tube of corresponding internal diameter, the diameter 0.5-1mm less of the internal diameter of conduit leading cylinder after core mated with catheter diameter.Originally the advantage leading core is front end is hemisphere, and front cylinder is comparatively thin, is easy to moulding, enters tracheal strips more easily by glottis, can reduce the damage to vocal cords and larynx.Simultaneously comparatively thin relative to endotracheal tube owing to leading core, make the laryngoscope downward view of intubate doctor less by the stop of endotracheal tube.Insert and send the front end hemisphere of leading core when leading core and front cylinder to be introduced into glottis, gradually increase thick round platform subsequently, rear cylinder enters glottis, the front tooth labelling of now leading on core is crossing with the front tooth of patient, stops inserting to send leading core, then endotracheal tube is inserted trachea along leading core.Be no matter common tracheal intubation or difficult intubation time, originally lead core and the visual field of intubate doctor can be made more clear, damage vocal cords, epiglottis and Pyriform sinus etc. can be avoided, the once success rate of intubate can be significantly improved.
Three, summary of the invention
This utility model design be a kind of assisted gas cannula lead core, by leading the front hemisphere of core, front cylinder, round platform, rear cylinder, rear quarter form, and on rear cylinder, hemisphere 15-22cm place in distance front end establishes a front tooth labelling.Originally the advantage leading core is front end is hemispherical, and front cylinder is comparatively thin, is easy to moulding, according to the thickness of patient's trachea, first selects the conduit of corresponding internal diameter, the diameter 0.5-1mm less of the internal diameter of conduit leading cylinder after core mated with catheter diameter.General estimation can first be inserted in endotracheal tube by leading core without the patient of obvious difficult intubation, the direction of leading core is consistent with the direction of endotracheal tube, expose the front tooth labelling of leading on core, trachea is inserted again leading core, the front portion of the front end hemisphere of leading core, front cylinder, round platform, rear cylinder is allowed to pass through glottis successively, in time leading the front tooth of the contact of the front tooth labelling on core patient, fixedly lead core, then insert snorkel conduit to correct position along leading core; To the patient estimating at difficult tracheal intubation, first can insert tracheal strips by leading core, the front portion of the front end hemisphere of leading core, front cylinder, round platform, rear cylinder is allowed to pass through glottis successively, in time leading the front tooth of the contact of the front tooth labelling on core patient, fixedly lead core, again endotracheal tube being inserted tracheal strips along leading core, extracting and leading core.Originally leading core can avoid conduit to the damage of patient's larynx, will make to send pipe to be more prone to, and the once success rate of intubate will improve greatly.
